Problem summary
**************************************************************** * USERS AFFECTED: All IMS V13 users using REXX SPOC API * **************************************************************** * PROBLEM DESCRIPTION: IMS REXX SPOC API function CSLULGTP * * goes into a 100% CPU loop if the OM * * task is missing. * **************************************************************** * RECOMMENDATION: INSTALL CORRECTIVE SERVICE FOR APAR/PTF * **************************************************************** The IMS REXX SPOC API function CSLULGTP() - Retrieve command responses directly to REXX stem variables - goes into a loop if the OM task is missing because of a logic error in module CSLULFM1. CSLULFM1 calls an internal procedure within a loop. When OM is missing the procedure returns with RC=8. In this situation CSLULFM1 does not set the required controls to exit the loop and begins looping forever.
Problem conclusion
GEN: KEYWORDS: *** END IMS KEYWORDS *** The following part was updated: CSLULFM1 The CSLULFM1 routine was modified to set the proper controls when a non-zero RC is received from internal procedure calls to prevent the endless loop.
