Error description
A Cobol batch job using WOLA service hung indefinitely. A dump of the job shows that there is a thread hung waiting for a response from a zWAS server that has already been recycled. The thread native and linkage stacks show the flow of control between the following modules leading up to the wait in BBOCLSCC for Comm Local Connect() processing. BBOAINV -> BBOAAPI -> BBOATRUP -> BBODPCN8 -> bbodpcrt -> BBOCLSCC. The root cause is a narrow window between server shutdown and application startup. This APAR was taken to improve product reliability by augmenting the WOLA client to take advantage of the local comm timeout introduced by PM61861. With this code change the WOLA batch job thread will timeout allowing the job to terminate gracefully.

Problem summary
**************************************************************** * USERS AFFECTED: Users of WebSphere Application Server * * using Optimized local Adapters for * * WebSphere V8.0 and V8.5 * **************************************************************** * PROBLEM DESCRIPTION: WebSphere Optimized Local Adapter * * (WOLA) cllents hang when connecting to * * a Websphere server that is being * * shut down. * **************************************************************** * RECOMMENDATION: * **************************************************************** The existing wait time defined on the WOLA API's BBOA1CNG, BBOA1RCA, BBOA1INV and BBOA1SRV was not being honored when creating a connection to the server. In addtion the WOLA API BBOA1REG does not have a connection timeout defined when establishing new connections for the connection pool
Problem conclusion
The wait time parameter defined on the WOLA API's BBOA1CNG, BBOA1RCA, BBOA1INV and BBOA1SRV is now honored when connecting to the server. In addition, a default wait time of 60 seconds is used by the BBOA1REG API when establishing new connections for the connection pool. APAR PI49306 is currently targeted for inclusion in Fix Packs 8.0.0.13 and 8.5.5.10 of WebSphere Application Server. In addition, sysroute APAR PI61046 will provide the fix in WebSphere Application Server V7.0 Fix Pack 7.0.0.43.
