Error Cannot Find The Pool Manager Reference
Most exceptions that occur when a data source is used to connect to a database will have the com.ibm.ws.rsadapter package in the stack trace of the exception. You should fix the application code to resolve the problem. good luck. The application must wait for a free connection to become available. http://haywirerobotics.com/error-cannot/error-cannot-resolve-a-multiname-reference-unambiguously.html
The reason code helps you to understand the root cause of the problem. This can occur for numerous reasons, including the following: 1 The application tries to get a connection and fails, as when the database is not started. 2 A connection is no When there is a stale database connection, WebSphere Application Server issues a StaleConnectionException. Some additional information on the J2CA0020E error can be found in the following technote: http://www-01.ibm.com/support/docview.wss?uid=swg21206150 Resolving the problem Change the following properties for connection Pool and Session Pool properties: Unused timeout http://www.ibm.com/support/docview.wss?uid=swg21206150
When the server stops successfully, the stopServer.log file contains the following in the last two lines: Server stop request issued. No, continue to question 5. Each connection in the connection pool has its own session pool.
- The Control Panel folder displays.
- Setting these properties to zero mean that JMS Connections and JMS Sessions will no longer be closed off by the WebSphere Application Server Connection Manager if they have either been unused
- Connection wait problems and slow application performance when using connection pooling can occur when the web container is not configured properly.
- Are you seeing J2CA0045E errors withConnectionWaitTimeoutExceptions or slow performance in getting a connection?
- Troubleshooting JMS connection problems This section will help you to troubleshoot problems that occur when using a JMS connection factory to establish a connection to a messaging system such as WebSphere
- Refer to your database documentation or your DBA for more information about why a particular error or exception might have occurred.
Enjoy Back to top hhoang Posted: Fri Aug 20, 2004 7:22 am Post subject: NoviceJoined: 14 Nov 2002Posts: 21 I thought lowered the max connection pool help solve the problem but Yes, go to the Troubleshooting JMS connection problems section. The way the code appears to be written at the moment, the application will never be able to recover from the situation where the JMS Connection it is using has been Yes, the root cause of the problem is that the JNDI lookup of the data source by the application fails.
The problem is the connectivity between the appserver and the DB is getting disconnected some times and we are getting the following exception in the SystemErrlog. 2/7/09 22:08:33:877 GST 0000003a SystemErr I notice that every now and then my server throws an error and stops one of my message listener ports. No, continue to question 7. http://www.ibm.com/support/docview.wss?uid=swg21247168 I did a test yesterday by restart the MQ machine and I start seeing the same error messages on WAS site.
You should see one or more linked exceptions. com.ibm.ejs.j2c.ConnectionManager.allocateMCWrapper(ConnectionMa nager.java:1005) at . The required JVM environment entries might be different for other databases. If the JNDI name is jdbc/ds, you should see this entry in the SystemOut.log: WSVR0049I: Binding ds as jdbc/ds Also, check the application code and ensure that it is looking up
Troubleshooting stale connection problems This section will help you to troubleshoot problems with stale or invalid connections in the connection pool. at . Has anybody seen this before and if so could they point me in a direction towards removing it altogether? Yes, this means that there is a thread that has been running as long as the threshold defined in the hang detection policy.
Yes, the problem can probably be resolved by using the WSCallHelper class, provided by WebSphere Application Server. this content This doesn't necessarily indicate a problem, but you should review this technote for more details. Read about the Services utility in the Windows online help. Read the topic about the WASService command for information about adding and removing Windows services. Review this technote to resolve the problem.
Yes, continue to question 4. Mismatches between the two can also cause the java.lang.UnsatisfiedLinkError. If a direct JDBC connection fails with the same error that occurs within WebSphere Application Server, the problem is not specific to your WebSphere Application Server environment. weblink Close any JMS Connections being used by the application.
The Administrative tools folder displays.
Yes, this is not necessarily a problem. It is also preferable for you to have access to the source code for your application(s). J2CA0086W: Shareable connection MCWrapper id 686bbdf9 Managed connection [email protected] State:STATE_TRAN_WRAPPER_INUSE from resource jdbc/ds was used within a local transaction containment boundary. If the application tries to use the session again, the exception is issued.
they thought that the db was timing out but WAS was keeping the connection open. To troubleshoot this type of problem, you should have access to the administrative console and the SystemOut.log for your application server. This should help address common issues with this component before calling IBM support and save you time. check over here To troubleshoot this type of problem, you should have access to the SystemOut.log for your application server.
