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 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.
