This section outlines the restrictions and limitations of WebSphere Message Broker and WebSphere Event Broker, by component.
The WebSphere Message Broker Extensions, Samples, and Demos CD, which is described in the Installation Guide and in the information center topic "New function added in Version 6.0 fix packs", is available on Windows XP only.
On any UNIX platform, if you install the Configuration Manager component without the Broker component, and subsequently install the Broker into the same directory, several file symbolic links will be missing from the Broker's lil and lil64 directories. To avoid this problem, either:
To upgrade the Message Brokers Toolkit to Version 6.0.2.0 (from Version 6.0, Version 6.0.0.1, or Version 6.0.0.2), you must use the Rational Product Updater (RPU), which must be at level 6.0.2 or later. If you are currently using an earlier version of the RPU, you must upgrade it to Version 6.0.2 before upgrading the Message Brokers Toolkit. For information on upgrading the RPU, see the WebSphere Message Broker Installation Guide.
You can use the RPU to install the Message Brokers Toolkit (V6.0.2.0) either directly from the Web, or from a local system. The procedure for upgrading to Version 6.0.2.0 using the RPU is documented in the WebSphere Message Broker Installation Guide.
Additional instructions for upgrading the Message Brokers Toolkit and the Rational Product Updater are available from the WebSphere Message Broker and Event Broker V6.0.2.0 support page.
Warning: The RPU might show the installed product as Version 1.0.0. It might also display a "License not found" error, either in the logs, or as a pop-up window when you start the Toolkit. You might also see the following error reported in the installation logs:
"Command failed: D:\Program Files\IBM\MessageBrokersToolkit\6.0\rationalsdp.exe -clean -nosplash -application com.ibm.jxesupport.initialize"This problem and the solution are described in the following technote:
If you are using the RPU to install the package from a local system (rather than directly from the Web), the package you need to download varies according to the version that you currently have installed:
After you have upgraded to Version 6.0.2.0, you need to complete the following steps:
When you install RAC, you must enter the location of the Java runtime file java.exe on the Java Runtime page of the installation wizard. You must specify the location of a Java runtime file that is already installed. Do not specify the JRE installed with WebSphere Message Broker for this purpose; you must use an alternative JRE.
Technotes are available that cover several important issues that relate to the installation of Message Broker and Event Broker Toolkits with Rational Application Developer (RAD) or Rational Software Architect (RSA) products. You are strongly advised to refer to these Technotes when installing the Message Brokers Toolkit. Information on how to access these Technotes is given in the Support section of this readme file.
The first time that you run the Default Configuration wizard, it fails when creating a listener. To solve this problem, run the Remove Default Configuration wizard, and then run the Create Default Configuration wizard again. If this fails to correct the problem, you will need to start the listener manually by issuing the following command in the MQSI command window, and then running the Create Default Configuration wizard again:
runmqlsr -t tcp -p 1414 -m WBRK6_QUEUE_MANAGER
When you use response files for silent installation, they can contain an incorrectly set flag. As a result, if you select one or more specific components to be installed (rather than the full product), the selections are ignored and the full product is installed. To overcome this problem, you need to edit the response file and modify the appropriate flag as follows:
Change the following line:
-W setupTypes.selectedSetupTypeId=custom
to:
-W setupTypes.selectedSetupTypeId=
(that is, set to nothing) to prevent the default typical or custom installations (which install all components) from running.
If you develop message flows that use WebSphere MQ Real-time Transport with Multicast PGM support, you must install WebSphere MQ Version 6.0 or later on each affected broker system. You also need to apply APAR IC47032 and USERMOD ANPGM01.
WebSphere Message Broker is supported in the Global zone or a whole root non-global zone, and must be installed separately in each.
If you have one or more components of WebSphere Message Broker already installed on a computer, and you then try to install any additional components, InstallShield checks for sufficient free disk space to install the entire product and not just the additional components that you want to install. As a result, you might be unable to install the additional components even though enough space is available on the computer. If enough space is available to install the whole product, you can install the selected components successfully. If not, you will need to uninstall the previously installed components and start again.
The Command Assistant Wizard cannot currently administer Configuration Manager components. A fix will be made available to rectify this situation.
If you want to install the WebSphere MQ V6 Explorer plug-ins for use with WebSphere Message Brokers Toolkit, you can use the Eclipse Update Manager. However, you must first install the V6.0.1 refresh pack for WebSphere MQ V6.
From the Eclipse toolbar, select Help > Software Updates > Find and Install. Select the New features option. Add <WebSphere MQ installation directory>/eclipse as a new local source and the Explorer features will be shown as available for installation.
As a workaround before the availability of the V6.0.1 update, you can manually copy the directories containing the WebSphere MQ Explorer features and plug-ins into the WebSphere Message Brokers Toolkit directory. After restarting the WebSphere Message Brokers Toolkit, you can open WebSphere MQ Explorer as a new perspective.
When you use the -options-record flag to create a response file for use during silent uninstallation, the response file contains an incorrectly set flag. As a result, if you select one or more specific components to be uninstalled (rather than the full product), the option is ignored and the full product is uninstalled.
To overcome this problem, you need to edit the response file and modify each line that specifies whether an individual component is to be uninstalled. This means that you need to change all instances of the following string:
-P feature.active=trueto the following string:
-P feature.activeForUninstall=truewhere feature is the name of the component to be uninstalled.
You also need to change all instances of the following string:
-P feature.active=falseto the following:
-P feature.activeForUninstall=falsewhere feature is the name of the component that you do not want to uninstall.
You must ensure that one of these statements (either activeForUninstall=true or ctiveForUninstall=false) exists for every component.
However, in the generated response file, activeForUninstall statements might be present that relate to components that have not been installed. If such statements exist, ensure that the activeForUninstall option for each of these components is set to true. If the activeForUninstall option is set to false for these components, the uninstallation program fails.
If you use the following Dublin Adapter solutions, contact Dublin Adapters Support (dubadsup@ie.ibm.com) for a version of the solution that has been tested on Version 6 of the Message Broker. Do not simply migrate the Version 5 solution as this can result in some subtle differences in behavior from Version 5:
Before attempting a migration of the solution to Version 6, if you use the following Dublin Adapter solutions, contact Dublin Adapters Support (dubadsup@ie.ibm.com) to check whether a version is available that has been tested on Version 6 of the Message Broker, and whether there are any further issues:
If you are migrating a message set from WebSphere MQ Integrator Version 2.1, and the message set contains an industry standard TDS physical format such as SWIFT, and if you intend to deploy the message set to a Version 2.1 broker (or to a Version 5 broker that is at a service level prior to Fix Pack 3), you might need to complete the following steps after using the mqsimigratemsgsets command.
If you do not make this update, the following message appears when you add the message set to a bar file (CSD3 in this message refers to Fix Pack 3):
BIP0202W This dictionary requires a version 5 CSD3 or above broker. TDS Format "SWIFT" uses "Strict Numeric Checking". This option is not supported by brokers earlier than version 5 CSD 3.
You must correct this error before you can deploy the bar file successfully.
When using the Real-timeInput node with publish/subscribe applications, a memory leak in the DataFlowEngine process might occur on all distributed platforms. The memory used by the DataFlowEngine process constantly increases, depending on the platform and the number of publish/subscribe clients.
If the DataFlowEngine process runs out of memory, it stops. On Windows, an ABEND file and a dump are generated in the 'errors' folder. On other systems, an ABEND file and a core file are generated. The DataFlowEngine process then restarts.
For example, using a single message flow (with no additional instances) in one broker with one execution group, and 80 publish/subscribe clients on a 4 way - 4GB computer running Windows, the DataFlowEngine process stopped after approximately 1.5 hours.
You are likely to see errors in the system event log such as:
Java Virtual Machine OutOfMemoryError occurred. The JVM has reported an OutOfMemoryError situation.
The ABEND File might contain errors like:
File: F:\build\S000_P\src\DataFlowEngine\JavaNodeLibrary\ImbJmsIpJNIJmsIpNode.cpp Line: 417 Function: Java_com_ibm_broker_server_JmsIpNode_logFatalError AbendAction: 3
To resolve this problem, it might be necessary to stop and restart the broker, and increase the Java Virtual Machine Heap size. You can eliminate some memory issues if you use the Real-timeOptimizedFlow node instead of the Real-timeInput node.
On z/OS platforms: If you include a Trace node, with its destination property set to "User Trace", in a high throughput message flow, the owning execution group might stop (abend S2C1). Because Trace nodes are always active, they should not normally be included in production flows. But to avoid this problem, ensure that connected Trace nodes are not included in high throughput flows because, as they are always active, these nodes have a high I/O overhead.
In order for the Mapping node to work with the MIME domain parser, you must use either the mime_multipart.xsd or the mime_nested_multipart.xsd provided by the Message Brokers IBM Supplied Message Definitions.
To enable subscribers to receive retained publications, you need to stop and restart the brokers in your Publish/Subscribe domain.
If you want to use the flow debugger, the names of a broker and execution group must be in English alphabet characters, whatever the locale of the computer.
On AIX, an XA enabled WebSphere MQ queue manager (on WebSphere MQ Version 5) fails to start cleanly if a link from /usr/lib to the Oracle supplied 32-bit client library 'libclntsh.a' has not been created.
To resolve this problem, issue the following command (as root):
ln -s $ORACLE_HOME/lib32/libclntsh.a /usr/lib/libclntsh.a
This command allows the queue manager to start cleanly.
This problem does not apply to WebSphere MQ Version 6.
If you have Oracle9i or Oracle10g and DB2v8 installed on the same HP-UX system you might experience a problem using the broker with an Oracle broker database.
The broker is prevented from starting and an abend file is created. In the file you see symbols from the Oracle libraries resolved in a DB2 library, giving rise to a segmentation violation.
If you want to use Oracle with the broker, and have DB2 installed on the same HP-UX computer, disable the <install_dir>/lib/imbdfdb2.lil file by renaming imbdfdb2.lil to something else. The rename stops the broker getting DB2 libraries that the HP-UX operating system then uses to resolve the Oracle symbols.
Oracle XA is not supported with 64-bit execution groups on AIX, Solaris, and HP-UX.
The manipulation of Unicode data in databases is not supported.
In addition to the restrictions described in the "Supported Databases" topic in the information center, note that only the 32-bit Informix Dynamic Server and 32-bit Client SDK are supported. The 64-bit Informix server and client are not supported.
The minimum required version of the Informix client is SDK V2.90 with UC4X8 fix pack; contact Informix to request this fix pack.
You cannot deploy message flows to 32-bit execution groups in a broker started on HP-UX (PA-RISC platform) and HP-UX (Integrity platform) systems that are running HP-UX 11.23 with DB2 Version 9.1.
Deployment to 64-bit execution groups is unaffected.
The information center topic that describes the sample obbc.ini file (topic ah14449_) is incomplete:
The WebSphere Message Broker Installation Guide and the WebSphere Event Broker Installation Guide refer to HP-UX (Itanium platform), which has been renamed HP-UX (Integrity platform).
In Chapter 1 of the WebSphere Message Broker Installation Guide, the table containing information about supported databases (Table 4) contains incorrect information about Informix support. The correct details for Informix support are:
Platforms not listed above do not support Informix databases.
In the information center topic that describes the ROUND function, the examples show an underscore character between MODE and RoundingMode, which is incorrect. The underscore character should be replaced by a space. For example:
ROUND(5.5, 0 MODE_ROUND_UP); returns 6is incorrect, and the correct form is:
ROUND(5.5, 0 MODE ROUND_UP); returns 6
The following topics in the information center describe the ability to drag and drop elements in the Mapping Editor:
However, in Linux, the drag and drop function does not work correctly in the Mapping Editor. Therefore you cannot drag and drop a source element from the source pane to a target element in the target pane, or drag a source element from the source pane to the edit pane. In addition, you cannot move elements up or down by dragging and dropping an element in the MapScript pane. Alternative methods of performing these actions are documented in the information center. To move elements in the MapScript pane, you can use either Copy and Paste, or the Delete and Recreate/Populate actions.
In the information center topic about ACL permissions (topic ap12520_), the table should include a section for the ConfigManagerProxy object, as shown in the following table:
| Object | Permission | Rights |
|---|---|---|
| ConfigManagerProxy | Full control |
|
| View |
|
In addition, the following information should be added to the Topology section of the table:
| Object | Permission | Rights |
|---|---|---|
| Topology | Full control | Full control permission for all Brokers |
The authorization that is required for the commands mqsicreateaclentry (topic an23030_), mqsideleteaclentry (topic an23040_), and mqsilistaclentry (topic an23050_) is incorrect in the information center. The following authorization is required:
The user ID used to invoke this command must have full control permissions for the object being changed; see "ACL permissions" (topic ap12520_) for more information. In addition, for Linux and UNIX systems, the user ID must be a member of mqbrkrs.
The GoogleAPINode sample for the JavaCompute node, one of five JavaCompute samples in the Samples Gallery, now fails because of a change in the Google API it uses. You cannot use this sample at this time.
On Linux and Windows, some of the samples have minor usability problems. Before using them, refer to the
