Error description
Leak of a WOLA connection pool when issuing a Display from CICS to the WebSphere server that does not succeed. A display command against the WebSphere server which CICS was connected to, and noticied that the connection pool for these registrations was growing, with a large number of connections in "Err" state: 22.23.58 STC00799 BBOA0000I: TYPE: e JOBNAME: YOURJOB NAME: BBOAMVCSERVICE 22.23.58 STC00799 BBOA0001I: JOBNUM: 0 ACTIVE: true ACTIVE-CONNECTIONS: 7 22.23.58 STC00799 BBOA0002I: MIN-CONN: 1 MAX-CONN: 100 STATE: 00 TRACELEVEL: 00 22.23.58 STC00799 BBOA0024I: ID LSCB State 22.23.58 STC00799 BBOA0025I: 0x000002001607a2e0 0x7f1512b8 Rdy 22.23.58 STC00799 BBOA0025I: 0x0000020016079f20 0x7f153b78 Err 22.23.58 STC00799 BBOA0025I: 0x0000020016017930 0x7f153718 Err 22.23.58 STC00799 BBOA0025I: 0x00000200160172f0 0x7f1531a0 Err 22.23.58 STC00799 BBOA0025I: 0x0000020016017110 0x7f0f9aa0 Err 22.23.58 STC00799 BBOA0025I: 0x0000020016016e90 0x7f0f9640 Err 22.23.58 STC00799 BBOA0025I: 0x0000020016016ad0 0x7f0f90c8 Err Reviewing the logs, there is one Err connection for each time the WebSphere server is recycled. It appears that we are leaking one connection in the 'Err' (or Error) state for each WebSphere server recycle. If this were to continue, the link server would not be able to get a connection to process new requests, and it would appear to be hung. It would not process any more requests.

Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM WebSphere Application * * Server V8.0 and V8.5 * **************************************************************** * PROBLEM DESCRIPTION: Leak in a WOLA connection pool is seen * * when issuing a Display from CICS to the * * WebSphere server that does not * * succeed. * **************************************************************** * RECOMMENDATION: * **************************************************************** When a WebSphere server is either turned off, recycled or goes down for any other reason the WOLA connection in use may not be returned to the connection pool and instead leaks. This can happen if the client is using the BBOA1RCA service, or if the client is the WOLA CICS link server. If this occurs too many times, the connection pool will become exhausted and no connections can be obtained.
Problem conclusion
Code has been altered so that all connections will be returned back to the connection pool in all scenarios. APAR PM94136 is currently targeted for inclusion in Fix Packs 8.0.0.8 and 8.5.5.2 of WebSphere Application Server.
