This error is occurring when running an OPS/REXX program that requires ISPF services on an OPSOSF server.
OPS3092H ISPT036 Table in use -/- TBOPEN issued for table ISPPROF that is in use, ENQUEUE failed.
OPS/MVS
Multiple OPSOSF servers or LPARs are attempting to allocate and open the same ISPPROF dataset concurrently, leading to an ENQUEUE failure.
Review the ALLOCSPF REXX program (sample delivered in the CCLXSAMP library) to make sure it is allocating different ISPF profile datasets for each OPSOSF server.
