IBM introduced closing nighttime that it is promoting the final components from its 1995 acquisition of Lotus to Indian firm HCL for $1.8 billion.
IBM paid $3.5 billion for Lotus again within the day. The massive pieces here are Lotus Notes, Domino and Portal. These had been a great a Part of IBM’s traffic company for a very long time, however closing yr huge Blue started to draw back, promoting the edifice part to HCL, while keeping manage of revenue and marketing.
This announcement marks the conclusion of the line for IBM involvement. With the construction of the platform out of its control, and in want of money after spending $34 billion for red Hat, perhaps IBM with no concern decided it not made suffer to maintain any Part of this in-house.
As for HCL, it sees an occasion to continue to construct the Notes/Domino enterprise, and it’s seizing it with this buy. “The colossal-scale deployments of these items supply us with an excellent chance to attain and serve thousands of international enterprises throughout a wide reach of industries and markets,” C Vijayakumar, president and CEO at HCL technologies, stated in a press release announcing the deal.
Alan Lepofsky, an analyst at Constellation research who keeps shut watch on the traffic collaboration area, says the sale could symbolize a cleanly birth for utility that IBM hasn’t in reality been paying close attention to for a while. “HCL is artery more interested in Notes/Domino than IBM has been for a decade. they're investing heavily, making an attempt to rejuvenate the brand,” Lepofsky instructed TechCrunch.
whereas this application may additionally deem long within the tooth, Notes and Domino are nonetheless in expend in lots of corners of the business, and this is very convincing in EMEA (Europe, headquarters East and Africa) and AP (Asia Pacific), Lepofsky observed.
He added that IBM seems to exist absolutely exiting the collaboration house with this sale. “It looks that IBM is performed with collaboration, out of the online game,” he observed.
This circulate makes sense for IBM, which is affecting in a special route because it develops its cloud business. The red Hat acquisition in October, in specific, shows that the traffic desires to embody private and hybrid cloud deployments, and older software relish Lotus Notes and Domino don’t basically play a job in that world.
The deal, which is discipline to regulatory approval processes, is anticipated to close within the middle of subsequent yr.
When IBM bought Lotus for $3.5 billion in 1995, it looked as notwithstanding the venerable computing colossal was just about to lock up the software trade and coast to unstoppable gains.
Eighteen years later, Lotus appears greater relish a millstone round IBM’s neck than a flywheel giving it additional velocity.
in accordance with a document within the Wall street Journal, in enhance of IBM’s q4 revenue unencumber today, Lotus changed into the weakest performer in IBM’s application portfolio, shedding 6.four % of its sales quantity within the first nine months of 2012.
It doubtless debts for about $1 billion in annual profits, based on estimates sourced by artery of the WSJ, or one-sixth to at least one-fifth of IBM’s universal software enterprise.
paradoxically, Lotus once led the artery toward today’s most well liked commercial enterprise technologies, the collaborative software that helps groups communicate and toil collectively on projects. one of the most success reports of that niche is Yammer, which Microsoft got ultimate 12 months for $1.2 billion. So, why is IBM sitting in the back of the pack as a substitute of leading from the front?
Lotus, which made the primary blockbuster “killer app” within the Nineteen Eighties (Lotus 1-2-three, a phenomenally a hit spreadsheet software), went on to create Lotus Notes, a powerful groupware suite that got here out within the early Nineties earlier than any person had any concept what “groupware” was.
I used it substantially at a brace of agencies I worked with. originally, it was esoteric and powerful. relish most end-users of Lotus Notes, I used it basically as an e-mail software. It had its quirks, but it surely worked. but there was one more dimension to Notes, an impressive, programmable backend that will let you create databases and workspaces for collaborative work, contact administration, suggestions sharing, and conversation.
today, we’d designation it a collaboration tool or a corporate social-media tool, and it could exist internet-primarily based and requirements-compliant, relish Yammer, Jive, and Huddle. in the absence of requirements, Notes’ engineers needed to invent every Little thing themselves, making it a clever but proprietary solution.
but long before these internet-based startups came alongside, Notes became already losing its cool. The client application grew to become massive and bloated. It was costly to set in compel and complicated to customize.
because the internet won recognition within the late Nineteen Nineties, Lotus brought requirements, relish POP3 and IMAP electronic mail interfaces. They didn’t achieve this smartly with the necessities department, although, riding any person who had to expend an internet mail client with a Lotus Notes mail server fully insane.
The upshot is that, just as the cyber web grew to exist typical, Lotus Notes became worrying and out of date.
sure, it changed into nevertheless potent, however unlocking the power of Notes commonly required professional advantage, giving upward thrust to a sector of Notes consultants. No amaze that these consultants are having a hard time getting taken significantly these days. The WSJ quotes a Notes consultant who complains about his reception:
“i Go to a celebration, and that i presently bag insulted,” says Eugen Tarnow, a director of the consultancy Avalon traffic programs, which sells the getting ancient email application to companies. “they are saying, ‘Lotus Notes, that’s nonetheless round?’ It’s no fun.”
unluckily, IBM’s engineers realized the significance of standards compliance too late and didn’t bake interoperability into Lotus Notes well adequate or early ample. So, as potent as Notes could be, it changed into and is sick-organized to toil in today’s API-wealthy cloud atmosphere.
IBM has more concomitant social-media utility, too, however handiest makes about $55 million per 12 months from that segment of its company. So the problem for IBM is to continue milking as a all lot salary because it can from Lotus, while step by step shifting the branding and the salary to more recent, sexier lines of company. One illustration: Renaming its annual Lotus convention, Lotusphere, as “Connect2013.” Yeah, that’ll aid.
We’ll exist observing to view if the income report sheds any longer mild on IBM’s efforts to turn Notes around. however as for me, I’m no longer conserving my breath.

This chapter is from the bespeak
Before delving into the inner workings of the OSGi console, it is best to briefly interpret OSGi. OSGi stands for Open Services Gateway initiative framework. This framework allows software to exist written and executed as independent components. In OSGi-speak, these components are referred to as bundles. OSGi is used in a wide reach of applications, from client programs such as Eclipse and IBM Lotus Notes, to mobile phones, to server applications such as IBM Lotus Domino. As a result of their modular nature, OSGi bundles can exist started, stopped, and debugged on an individual basis, without the necessity for stopping or restarting the entire platform. Both the Domino server and the Notes client expend Eclipse’s implementation of OSGi (Equinox) as their OSGi runtime platform.
OSGi was added to the Domino platform in release 8.5.2. As a result, in Domino 8.5.2, the XPages runtime was repackaged to rush as OSGi bundles (instead of just a regular collection of Java JARS), moreover referred to as Eclipse plug-ins.
The OSGi console allows for the input of commands that the OSGi platform then performs. The platform posts the results of such commands back to the console. The OSGi platform itself has a all host of commands that can simplify the troubleshooting of problems. The OSGi console can assist developers in developing XPages controls and applications, as well as assisting champion personnel in diagnosing runtime issues. Developers who extend the XPages runtime by creating libraries will find the OSGi console commands to exist a particularly powerful tool in analyzing problems. The OSGi console is of particular expend when the developer/administrator needs to know whether individual plug-ins (or sets of plug-ins) are loading correctly or which version of a plug-in is in use.
As mentioned earlier, OSGi is embedded within both the Notes client and the Domino server. Depending on where your XPages application is running (whether on the client or the server), your mode of accessing the OSGi console will vary. They start by explaining how to access the OSGi console on the Domino server.
OSGi is embedded within the HTTP chore on the Domino server, as a result, the OSGi console is started automatically whenever the HTTP chore is started. OSGi console commands are routed to the OSGi console via the HTTP task. That is, when entering an OSGi console command on the Domino server, the user must bid the HTTP chore to route the specified command to the OSGi console—for example:
tell http osgi <<command>>
Here, <<command>> is the designation of the OSGi console command. Any OSGi command can exist executed using the preceding syntax.
When it comes to OSGi commands, every developer and administrator should know several rudimentary commands. These commands can exist your “go to” commands when problems arise—say, when you suspect bundle loading might exist a factor. Even when you upshot not deem that bundle loading is the problem, it is often best to first validate that the bundle is actually loaded before proceeding with other debugging techniques.
Table 3.2 lists some of the more commonly used OSGi commands that are available to expend for diagnosing plug-in issues on the Domino server (and moreover the Notes client). In Table 3.2, bundle-symbolic-name is referenced extensively. This is the designation by which the OSGi platform references bundles. bundle-symbolic-name correlates directly to the Bundle-SymbolicName manifest header, often referred to as the plug-in name.
Table 3.2. OSGi Console Commands
tell http osgi diag <bundle-symbolic-name>
Diagnoses the status of the bundle whose designation is provided. Determines whether the bundle is resolved and, if not, states why the bundle is not resolved.
tell http osgi ss <bundle-symbolic-name>
Lists the status of utter bundles in the system. Optionally, a symbolic designation or a symbolic designation prefix can exist provided to obtain the status of a particular bundle or a subset of bundles.
tell http osgi start <bundle-symbolic-name>
Starts the bundle with the specified symbolic name.
tell http osgi stop <bundle-symbolic-name>
Stops the bundle with the specified symbolic name.
tell http osgi b <bundle-symbolic-name>
Prints metadata relating to the specified bundle.
tell http osgi headers <bundle-symbolic-name>
Lists the OSGi headers for the specified bundle.
tell http osgi help
Lists utter the OSGi command available on the server, along with some text describing each command.
All the commands listed in Table 3.2 can exist entered via the Domino server console, with the results of such commands being printed back to the console, as illustrated in device 3.4.
Figure 3.4. Running an OSGi command on the Domino Server Console
All the commands referenced in Table 3.2 can alternatively prefer the bundle id as a parameter (instead of the bundle-symbolic-name). The bundle id is a numeric ID that the OSGi runtime assigns to the bundle during platform initialization. The ID might vary from instance to instance of the platform, but users might find it easier to input than having to enter the entire bundle symbolic name. Examples of how to determine and expend the bundle id are given later in this chapter.
Rarely does a lone OSGi console command retort utter the questions on why a plug-in is not loading or operating as expected. The following sections interpret in greater detail how you can expend each of these commands and the results you can await to view from executing such commands.
This is one of the most valuable commands in your arsenal and will likely exist the one you’ll expend most frequently when diagnosing issues. You can expend this command to determine whether a bundle is resolved within the OSGi platform. The status returned by this command will exist one of the following:
No unresolved constraints
If No unresolved constraints is the returned status, it suggests that the system has recognized the bundle and that utter dependencies of the bundle are satisfied. When an Unresolved constraint status is returned, it suggests that one or more bundles or packages that the bundle requires are missing or cannot exist loaded. It is worth noting here that a bundle might still fail to start even though the OSGi console reports that the bundle has been resolved. If a bundle fails to start and is resolved, some code in the bundle’s activator likely is failing (throwing an exception).
tell http osgi diag com.ibm.xsp.core
Listing 3.8 shows the typical output of running the diag command against the com.ibm.xsp.core plug-in.
Listing 3.8. Result of Running the diag Command Against a Specific Bundle—Successful Case
> bid http osgi diag com.ibm.xsp.core
10/17/2011 09:43:14 PM
10/17/2011 09:43:14 PM No unresolved constraints.
In this case, the diag command reports that there were No unresolved constraints against the entered bundle symbolic name—in other words, the system recognizes the given bundle. Upon closer examination, the user can obtain further information about the bundle in question. It can determine where the bundle being used by the platform is installed, and the platform-assigned bundle id can moreover exist obtained.
From reading the console output, the user can view that the bundle is installed to ../../shared/eclipse/plugins/com.ibm.xsp.core_126.96.36.19910629-1645. The location specified is relative to the osgi/rcp/eclipse directory, which is a child of the Domino program directory. In this case, the console output indicates that the plug-in is installed at: <domino program directory>/osgi/shared/eclipse/plugins.
Finally, the output states the platform-assigned bundle id for the specified bundle. 119 is the id assigned to this bundle in this example. As stated previously, the OSGi commands listed here can expend the bundle id interchangeably. In this example, executing the following command has identical output to that in Listing 3.8.
tell http osgi diag 119
Listing 3.9 shows sample output of running the diag command in an unsuccessful scenario.

ibm.xsp.extlib.sbt_188.8.131.52108111413.jar  09/09/2011 04:05:51
PM Direct constraints which are unresolved: 09/09/2011 04:05:51 PM
Missing host com.ibm.xsp.extlib_0.0.0.
In Listing 3.9, you can view that the OSGi platform reports that the bundle in question is not resolved as a result of a missing dependency. They can view from the console output that the OSGi platform has actually organize the bundle that they are looking for (com.ibm.xsp.extlib.sbt), but as one of the bundles that com.ibm.xsp.extlib.sbt depends on is not resolved, the com.ibm.xsp.extlib.sbt bundle does not bag resolved itself. Looking a Little more closely at the console output, they can determine the following:
The bundle com.ibm.xsp.extlib.sbt is installed at ../../../data/domino/workspace/applications/eclipse/plugins/com.ibm.xsp.extlib.sbt_184.108.40.206108111413.jar. They now know that this path is relative to the <domino program directory>/osgi/rcp/eclipse directory. Hence, they can deduce that com.ibm.extlib.sbt is installed at the <domino program directory>/data/domino/workspace/applications/eclipse/plugins/ directory.
The OSGi platform–assigned bundle id for this bundle is 116.
One other tidbit of information can exist extracted from the console output, in this case. The final line of the output tells us that the host is missing:
Missing host com.ibm.xsp.extlib_0.0.0
This tells us that the bundle they are looking for (com.ibm.xsp.extlib.sbt) is, in fact, a plug-in fragment, and the unresolved constraint (com.ibm.xsp.extlib) is the host plug-in.
ss, ss <bundle-symbolic-name>, or ss <bundle-name-prefix>
Similar to the diag command, this command quickly determines the status of a particular bundle—or utter the bundles installed in the platform. Users can optionally specify a bundle designation or a bundle designation prefix to bag the status of specific bundles. The returned status shows the bundle id, state, and bundle designation of utter bundles. In many situations, this command is just as useful as the diag command because it moreover reports the status of a bundle. This command does not bid the user why a particular bundle is not loading, but it does bid the user the condition of a bundle.

Listing 3.10 lists a subset of the information that displays when this command is rush in a unostentatious server environment. However, the listing does point to utter the information needed to understand the output of the command.
The command outputs several famous pieces of information about each bundle:
Bundle-id—for example, 2, which is the OSGi platform–assigned ID of the bundle.
Bundle state—for example, RESOLVED, which is the condition of the bundle within the OSGi platform. A bundle can esteem one of seven states. Table 3.3 explains utter of these.
Bundle name—for case com.ibm.eclipse.equinox.preferences.nl_220.127.116.1110624-1648, which is the bundle symbolic designation with its version information appended to the name.
Master or Fragments—for example, Master=71. This data tells whether the bundle in question is a plug-in or a fragment. If the bundle specifies neither Master nor Fragments, it is automatically implied that the bundle is a plug-in bundle. The digits corresponding to the fragments or plug-ins are the OSGi platform–assigned bundle ids of the fragments or the master plug-in of the bundle in question.

Similar to Listing 3.10, Listing 3.11 shows the results of executing the ss command, only this time the command is passed a bundle symbolic designation as a parameter. The ss command finds utter bundles on the system that either start with the parameter or esteem a bundle symbolic designation that is the identical as the parameter. Listing 3.11 lists utter the bundles, along with their bundle id and state.
Table 3.3 lists utter the feasible states of an OSGi bundle.
Table 3.3. OSGi Bundle States
The bundle is uninstalled and is unusable.
The bundle has been installed, but the platform has not yet resolved it.
The bundle has been resolved and is in a position to exist started.Note that it is still feasible for the bundle to fail to start, even though it has been resolved by the environment.
Similar to RESOLVED, the platform has resolved the bundle and is in a position to exist started. The bundle is not yet lively because it has been configured (via its bundle manifest) to exist initialized lazily–that is, only when another lively bundle references the bundle will it exist activated.
The bundle is in the process of starting. Either another bundle has specifically caused the bundle to start (by referring to a class within the bundle) or the user has manually started the bundle via the console. Rarely is a bundle in this condition because it is transient.
The bundle is in the process of shutting down. Similar to STARTING, a bundle rarely is in this state.
The bundle is running within the OSGi platform.
Developers and administrators should exist sensible that, on the Domino server, the condition of a bundle is not persisted from one session to the next—that is, after the HTTP chore is restarted, any bundles that were started manually in the previous session must exist started again. Luckily, the ss command has an dispute for filtering utter bundles in a given state. The ss command can filter the bundles based on their state, by appending -s [state] to the command syntax.
tell http osgi ss -s active
Figure 3.5 shows the output of running the ss command with the -s lively argument.
Figure 3.5. Result of running the ss command in the Domino server console
This command requests that the platform manually start the specified bundle. Calling this command does not guarantee that the specified bundle will exist started. An exception can still occur during bundle initialization that would occasions the bundle initialization to fail. Performing an ss command after the start command reports the status of the bundle. This command is helpful when a current bundle has been installed on the server, but the administrator or developer is not in a position to restart the HTTP chore to start the current bundle.
tell http osgi start com.ibm.xsp.extlib.sbt
Figure 3.6 shows that, by running a combination of the ss and start commands, a bundle can exist started and its condition can exist verified.
Figure 3.6. Result of running the start and ss commands in the console
This command tells the platform to stop the specified bundle. Users should exist heedful when calling this on a production environment. In some cases, it might not exist feasible for the platform to stop the bundle. If this is the case, the judgement will exist printed to the console.
tell http osgi stop com.ibm.xsp.extlib.sbt
Figure 3.7 shows how running a combination of the ss and stop command stops a bundle and verifies its state.
Figure 3.7. Result of running the start and ss commands in the console
This command prints utter metadata relating to the specified bundle. The metadata includes imported packages, required bundles, exported packages, bundle location, and so on. This command is useful when the developer needs to quickly verify that the bundle loaded by the platform has the meta information that the developer believes it has.

Commands are executed via the XSP Command Manager similar to any other command on the Domino server. The XSP Command Manager is running within the HTTP task, so the commands it executes must exist fed through the HTTP task, as in this example:
tell http xsp <<xsp command manager command>>
Table 3.1 lists utter the XSP Command Manager Commands.
Table 3.1. XSP Command Manager Commands
show data directory
Shows the location of the Domino server's data directory.
show program directory
Shows the location of the Domino server's program directory.
Displays the exact version of the XPages runtime that is installed and running on the Domino server.
Shows utter the variables/properties that esteem been set on the server's bootstrap.properties file. If a bootstrap.properties file does not exist, the XPages runtime provides reasonable recommended defaults.
Displays the modules loaded in the system. The XPages runtime dynamically loads each Domino database as a web application module.
Causes the services in the XPages runtime to exist refreshed. This is mainly reserved for future use.
Performs a live dump of utter objects on the Domino server's Java heap. Creates a dump file that must exist read by other tools (such as the Eclipse remembrance Analyzer); the file is not human readable.
Performs a Java dump, sometimes referred to as a thread dump or JavaCore dump, of the Domino server's JVM. The information collected during the dump operation is stored in human-readable format.
Performs a full system dump, sometimes referred to as a core dump, of the Domino server's JVM. The dump information is platform specific and contains utter the memory, process, and thread information for the JVM at the time the dump occurred.
These commands can greatly aid administrators and developers when trying to anatomize particular issues. The dump commands are of particular significance because they discharge diagnostic dumps on the server’s JVM but upshot not occasions the JVM or the server to stop operation.
show data directory
As the designation suggests, this command simply tells the user where the Domino server’s data directory resides on the operating system’s file system. In a Domino server environment, the data directory stores utter the databases that are available through the Domino server. The location of this directory is significant because utter applications running on the server will reside in this directory or within a subdirectory of this directory.
tell http xsp point to data directory
Figure 3.1 shows the results of running the point to data directory command on a Domino server.
Figure 3.1. Result of running the point to data directory command
show program directory
This command tells the user where the Domino server’s program directory resides on the operating system’s file system. This command can exist convenient for developers who are not familiar with a particular setup of an individual server machine. The command enables developers or administrators to quickly identify the file system location of the Domino server’s program directory.
tell http xsp point to program directory
Listing 3.1 shows the result of running the point to program directory command in the Domino server console.

This command shows the exact version of the XPages runtime that is installed and running on the Domino server. The version number is updated only when upgrading from one release to another of XPages core runtime. Adding or upgrading extensions such as the XPages Extension library does not update the version number. This command typically is used when a developer or administrator needs to validate which version of the XPages runtime is running on a particular server. current features are added to the XPages runtime with each release. These features can reach from current properties on existing controls to entirely current controls. Over time, a developer or administrator must validate that the version of XPages runtime is at the preempt release plane for the applications running on the server. This command enables the developer or administrator to quickly validate the XPages runtime version.
tell http xsp point to version
Listing 3.2 shows how to determine the version of the XPages runtime.
Listing 3.2. Result of Running the point to version Command in the Console
> bid http xsp point to version
09/20/2011 04:34:21 PM XSP Runtime Version: [DSI8.5.3] 20110629.1645
In the previous example, the version number can exist broken down as follows:
The DSI prefix is a constant, which does not vary from release to release.
8.5.3 represents the Major.Minor.Maintenance version number. The first digit is updated with each major feature release, the second digit is updated with each minor feature release, and the ultimate digit is updated with each maintenance release.
The final number (20110629.1645) represents the time stamp (yyyyMMdd.hhmm) at which the build in question occurred.
This command makes a request to the XPages runtime to print utter the settings in expend by the runtime. By default, the XPages runtime is configured with a host of default settings. These settings can exist overwritten by adding a bootstrap.properties file to the xsp directory, which resides in the Domino server’s program directory (for case C:\domino\xsp). As a result of being able to override the default settings in the XPages runtime (via bootstrap.properties), it is not guaranteed that the XPages runtime defaults will apply from server to server. This command enables developers and administrators to quickly list utter the current settings without needing to manually access various file system locations to determine which properties are being applied.
tell http xsp point to settings
Listing 3.3 shows the XPages runtime default settings being output to the Domino server console.

In some cases, it is necessary to set extra system settings or even overwrite existing settings. Being able to quickly anatomize which settings esteem changed can exist invaluable. Listing 3.4 shows a case in which some settings (xsp.sessionid.name) esteem been overwritten by bootstrap.properties and some current logging settings (log_configuration and logdir) esteem been added. Chapter 6, “Server-Side Debugging Techniques,” explains these settings

Each Domino database (.NSF) that is running within the XPages runtime is loaded by the XPages runtime as an application module. The point to modules command shows utter the databases (NSF modules) that are currently running within the XPages runtime. This command moreover shows registered system service modules that the XPages runtime automatically loads. This command is convenient for server administrators who necessity to know which XPages applications are being served by the XPages runtime at any point in time.
tell http xsp point to modules
Listing 3.5 shows utter the lively modules running within a Domino server that has sessions open for three XPages applications.

In Listing 3.5, six modules are listed. Three of these modules are XPages runtime system modules; the other three modules limn XPages applications that are currently running on the server.
xpagessbt.nsf, lsdemo2011.nsf, and oauthtokenstore.nsf are utter XPages applications that were running on the server when the command was executed.
XSP Resources is a module loaded by the XPages runtime; it is not configurable.
Default Http Registry Module is a module loaded by the Domino web container; it is not configurable.
OSGI WebContainer Bridge Service is a module loaded by the Domino to OSGi bridge; it is not configurable.
The core runtime modules are not configurable and can exist removed or added to in future releases.
This command was implemented with future extensions of the XSP Command Manager’s HTTP service in mind. As of release 8.5.3 of the Domino server, this command does nothing. It is intended to exist used with HTTP services and will enable services to exist refreshed as necessary without restarting the HTTP chore or the XPages runtime.
tell http xsp refresh
The heapdump command performs a live dump of utter objects on the Domino server’s Java heap. The operation creates a dump file that must exist read by third-party tools; the file is not human readable. The dump file can exist read using tools such as the Eclipse remembrance Analyser tool (www.eclipse.org/mat). Because the dump file is written in the IBM JVM bank dump format, it is necessary to install further add-ons to the Eclipse remembrance Analyser tool to read the bank dump information. You can download the add-on for the Eclipse remembrance Analyzer tool from www.ibm.com/developerworks/java/jdk/tools/dtfj.html. The heapdump command causes a dump file to exist generated in the server’s program directory, as demonstrated in device 3.2.
Figure 3.2. Result of running the heapdump command in the console
tell http xsp heapdump
When configured, the Eclipse remembrance Analyzer tool enables the user to read the content of the dump file and provide information on where remembrance is potentially being leaked and which objects are in expend when the dump occurs. device 3.3 shows sample output from the Eclipse remembrance Analyzer Tool.
Running the javadump command causes the server’s JVM to create a Java Dump file. Sometimes referred to as a thread dump or a Javacore dump, the dump information is written to disk in a human-readable format—the contents of the dump file can exist opened with applications such as Microsoft Notepad. The information stored as a result of a javadump is generally diagnostic information relating to the threads, stacks, locks, and remembrance that were in expend by the JVM when the dump occurred. Javadump files are of particular expend where the developer or administrator needs to quickly obtain system information (such as operating system version, JVM version, and loaded threads).
The Javadump file is lightweight by nature and can aid to quickly identify which threads are hung in the system.
tell http xsp javadump
Listing 3.6 shows the console output when the javadump command is executed.

In Listing 3.6, you can view the result of executing the javadump command. A Javadump file is written to the location specified in the console output. It is beyond the scope of this bespeak to Go into the details of reading the contents of dump files. However, in the case of Javadump files, a few tips can easily exist bestowed upon the reader to upshot reading the contents of the Javadump file easier. The dump file can essentially exist broken down into different sections:
Date and time of the javadump.
Operating system signal information (who initiated the javadump and how it was initiated). The signal information tells the reader whether the user initiated the dump or whether the operating system did so due to a program fault. The signal information is operating system specific.
Java (JVM) version.
Information about threads running when the javadump occurred.
Operating system and processor details.
Native libraries loaded by the JVM.
Full command line, including arguments, that the Domino server used to launch the JVM.
JVM monitor information.
Current stack for each thread running within the JVM.
For further in-depth information on how to read the contents of the Javadump file, view the following article from IBM support:
Alternatively, you can search for information on how to read a javacore dump file in your favorite Internet search engine.
The systemdump command is the most intensive of the three dump commands available through the XSP Command Manager. As a result, the footprint of the resulting systemdump file can exist quite large. The systemdump file contains particular information on the JVM’s threads, memory, and lively processes. When a Java application crashes as a result of universal protection weakness failure or as a result of a major JVM error, a systemdump file is generated by default.
