Collecting data for WebSphere MQ Java™ Message Service (JMS) problems with IBM WebSphere Application Server. Gathering this information before calling IBM support will help familiarize you with the troubleshooting process and save you time.
Note: This MustGather document applies only to WebSphere Application Server V5.1 and messaging that does not involve service integration technologies in V6.0, V6.1, V7.0 and V8.0. For problems involving service integration technologies, refer to MustGather: Service Integration Technology.
To improve the accuracy of complete data collection, IBM recommends you use the automated data collectors within IBM Support Assistant. Not only will the automated collector gather the equivalent of the manual process, it will also provide a secure file transfer of the collection to IBM.
Collecting data using the IBM Support Assistant Data Collector
- Go to the ISA Data Collector site for WebSphere Application Server.
- Start the ISA Data Collector:
- To run online, select the option to collect from this system using the current browser and click Start Collection.
- To run locally, select the option to collect from this or another system using a downloadable utility. Download and extract the zip file to your WAS_HOME directory. From a command line, run isadc.[sh|bat] or launch index.html to use the web interface.
- To run online, select the option to collect from this system using the current browser and click Start Collection.
- Select the Connectors > JMS Problem collector and click Start.
- Follow the prompts to automatically submit the collected data to IBM Support.
- What is the exact version and the edition (for example: base, Enterprise, WebSphere Business Integration Server Foundation, or Network Deployment) of WebSphere Application Server that is installed?
- What messaging system is your application connecting to (WebSphere Embedded Messaging, WebSphere MQ, or a Generic JMS Provider)?
- If you are using Publish-Subscribe messaging, what broker are you using (for example: Embedded broker, WBI Event Broker, WBI Message Broker, WebSphere MQ Pub/Sub Broker)?
- IMPORTANT: If you are using WebSphere Application Server (WAS) V7 or V8 and are connecting to WebSphere MQ, ensure the WebSphere MQ Resource Adapter on WAS has been updated after installation of a WAS Fix Pack. Here is a link to a document which lists the WAS V7 and V8 Fix Pack levels and corresponding WebSphere MQ Resource Adapter version:
Which version of WebSphere MQ is shipped with WebSphere Application Server?
Here are links to Information Center articles on maintaining the WebSphere MQ Resource Adapter and how to ensure the latest version is utilized, respectively:
WebSphere Application Server V8
Maintaining the WebSphere MQ resource adapter
Ensuring that servers use the latest available WebSphere MQ resource adapter maintenance level
WebSphere Application Server V7
Maintaining the WebSphere MQ resource adapter
Ensuring that servers use the latest available WebSphere MQ resource adapter maintenance level
- Provide a full description of the problem that you have encountered, including the stack traces of any errors or exceptions that are occurring. Provide any logs that contain the errors or exceptions.
- Under what circumstances does the problem occur? Does it occur every time a certain task is done or does it occur intermittently? Has this problem always occurred? If not, was a change recently made before the problem started to occur?
- If you are using the WebSphere JMS Provider (Embedded Messaging) or the WebSphere MQ V5.3 JMS Provider, provide the output from the mqver command. Example of the output:
Name: WebSphere MQ
Version: 530.10 CSD10
CMVC level: p530-10-L050419
BuildType: IKAP - (Production)
If you are using WebSphere MQ V6.0, provide the output from dspmqver -p2 instead of mqver.
- If you are using WebSphere MQ and the MQ server is remote, provide the output from the mqver (for MQ V5.3) or dspmqver -p2 (for MQ V6.0) command on the client side.
- If you are using the WebSphere JMS Provider (Embedded Messaging) or the WebSphere MQ JMS Provider, provide the output from the dspmq command. This will show the names and status of all queue managers on your system.
- If you are using Embedded Messaging, do the embedded queue manager and broker start successfully? Check for the following lines in the SystemOut.log file of the application server or the jmsserver (if running in a Network Deployment environment):
MSGS0050I: Starting the Queue Manager
MSGS0051I: Queue Manager open for business
MSGS0052I: Starting the Broker
MSGS0053I: Broker open for business
- What are the names and JNDI names of the JMS connection factories and destinations that are involved in the problem scenario? If a message-driven bean (MDB) is involved in the problem, what is the name of the listener port and the MDB?
- Send the SystemOut.log file for the application server or jmsserver on which the problem occurs:
- For WebSphere Application Server V6, V7, V8, and V8.5, the file is located in the following directory:
install_root/profiles/profile_name/logs/server_name
- For WebSphere Application Server V5, the file is located in the following directory:
install_root/logs/server_name
- For WebSphere Application Server V6, V7, V8, and V8.5, the file is located in the following directory:
- If you are using the WebSphere JMS Provider (Embedded Messaging) or the WebSphere MQ JMS Provider, send the WebSphere MQ error logs located in the following directories:
MQ_install_root/errors
MQ_install_root/qmgrs/queue_manager_name/errors
It is recommended that you clear all of these logs, and then reproduce the problem to produce a fresh set of logs to ensure that the data in the logs is from the current problem.
- Enable a WebSphere Application Server trace (NOTE: see step 4 to ensure the WebSphere MQ Resource Adapter is updated for WebSphere Application Server v7 and v8 prior to generating trace data) .
- Using ISA Lite
- Start ISA Lite.
- Select Connectors > JMS Problem.
- Follow the prompts to gather the trace and information about your problem.
- Start ISA Lite.
- For WebSphere Application Server V6, V7, V8, and V8.5:
- In the Administrative Console, expand Troubleshooting and select Logs and Trace.
- In the Logging and Tracing page, select your server and then Diagnostic Trace.
- Ensure that Enable Log is selected.
- Under Trace Output, select File, and accept the defaults.
- Click OK and save your configuration.
- Again expand Troubleshooting and select Logs and Trace.
- In the Logging and Tracing page, select your server and then Change Log Detail Levels.
- Enter the following trace string:
WebSphere Application Server V8.0 and V8.5:
*=info:JMSApi=all:Messaging=all:com.ibm.mq.*=all:WAS.j2c=all:Transaction=all
WebSphere Application Server V6 and V7.0:
*=info:JMSApi=all:JMSServer=all:Messaging=all:JMS_WASTraceAdapter=all:com.ibm.mq.*=all:jmsApi=all:WAS.j2c=all:Transaction=all
Note: The preceding trace specifications should be entered as one line with no breaks or spaces.
- Click OK and save your configuration.
- If WebSphere MQ V7 is being used as the JMS Provider, set the following JVM Custom Property (Application Servers > server_name > Process Definition > Java Virtual Machine > Custom Properties):
com.ibm.msg.client.commonservices.trace.standalone=false
- Click OK and save your configuration.
- Restart the application server.
- Reproduce the problem.
- Send the resulting trace output file.
- In the Administrative Console, expand Troubleshooting and select Logs and Trace.
- For WebSphere Application Server V5:
- In the Administrative Console, expand Troubleshooting and select Logs and Trace.
- In the Logging and Tracing page, select your server and then Diagnostic Trace.
- Ensure that Enable trace with the following specification is selected.
- In the Trace Specification field, enter the following:
Messaging=all=enabled:JMSServer=all=enabled:JMSApi=all=enabled:WAS.j2c=all=enabled:EJBContainer=all=enabled:jmsApi=all=enabled
Note: The preceding trace specification should be entered as one line with no breaks or spaces.
- Under Trace Output, select File, and accept the defaults.
- Click OK and save your configuration.
- Restart the application server.
- Reproduce the problem.
- Send the resulting trace output file.
- In the Administrative Console, expand Troubleshooting and select Logs and Trace.
- Using ISA Lite
- If you are using the WebSphere JMS Provider (Embedded Messaging) or the WebSphere MQ JMS Provider, enable a WebSphere MQ trace concurrently with the WebSphere Application Server trace.
- Run the collector tool to produce a JAR file containing your WebSphere Application Server configuration files and other logs that are useful to the WebSphere Application Server support team.
- Follow instructions to send diagnostic information to IBM support to send the files mentioned in the preceding steps.
