Error description This APAR addresses defects in WebSphere Application Server V4.0.1 for z/OS and OS/390.Local fix Problem summary **************************************************************** * USERS AFFECTED: All users of WebSphere Application Server * * V4.0.1 for z/OS and OS/390 * **************************************************************** * PROBLEM DESCRIPTION: APAR PQ70831 addresses various problems * * in WebSphere Application Server V4.0.1 * * z/OS and OS/390. * **************************************************************** * RECOMMENDATION: * **************************************************************** APAR PQ70831 addresses the following problems in WebSphere Application Server V4.0.1 for z/OS and OS/390: (MD15465) DB2 SQL Exception results because WebSphere is trying to execute on a closed connection. The WebSphere stacked transaction counter is not properly keeping track of how many stacked transactions has occurred. A trace similar to the following will result: Trace: 2003/01/13 22:08:47.736 01 t=AD46E8 c=4.79 key=P8 (13007002) FunctionName: com.ibm.ejs.container.EJSContainer SourceId: com.ibm.ejs.container.EJSContainer Category: WARNING ExtendedMessage: Bean method threw unchecked exceptionorg.omg.CORBA.portable.UnknownException: minor code: 0 completed: Maybe Trace: 2003/01/13 22:08:48.158 01 t=AD46E8 c=4.79 key=P8 (13007002) FunctionName: com.ibm.ejs.container.EJSDeployedSupport SourceId: com.ibm.ejs.container.EJSDeployedSupport Category: WARNING ExtendedMessage: Unchecked exception detected:com.ibm.ejs.persistence.EJSPersistenceException: find failed:; nested exception is: java.sql.SQLException: setInt method is not valid on a closed DB2SQLJPreparedStatement. Trace: 2003/01/13 22:08:49.116 01 t=AD46E8 c=4.79 key=P8 (13007002) (MD15613) SSL Client hang connecting to the HTTP SSL Transport. Server could issue error trace log, pthread_mutex_init failure. (MD15890) With the application of APAR PQ69259/ PTF UQ73459, heap corruption can occur due to a storage overlay when using the error log browser bborblog to view an error log entry greater than 4096 bytes long. The error occurs because no allowance is made for an extra byte of CR/LF that is added when formatting error log entries. For large entries, this single extra byte can overlay storage causing heap corruption.Problem conclusion APAR PQ70831 provides the following problem resolution: (MD15465) Support has been modified to correctly keep track of stacked transactions. This modifed suppport addresses the issue of executing with closed prepared statements. (MD15613) On an asynch I/O failure on the HTTP SSL Transport, the incorrect internal work element(ACRW) was queued, so the connection would not get cleaned up. Support has been modified such that the correct ACRW will now be created. (MD15890) Support have been modified to correctly obtained the storage required for formatting error log entries. APAR PQ70831 is associated with SERVICE LEVEL W401500 of WebSphere Application Server V4.0.1 for z/OS and OS/390.Temporary fix Comments
