Issue/Introduction
XCOM on z/OS is looping and consuming high CPU during a transfer job with an INQUIRE step. Had to cancel xcom and rerun the transfer which is now successful. Is there a solution to prevent the xcom loop situation?
TYPE=INQUIRE step in the transfer job abended with an 853 abend.
IGD300I AN ABEND OCCURRED DURING SMS PROCESSING
ABEND SYSTEM CODE=000 ASID=xxxx
COMPONENT NAME=SMS COMPONENT ID=DF101
Environment
XCOM™ Data Transport® for z/OS
Cause
This indicates that the MAXMOUNTWAIT timed out before a dataset allocation was completed. SVC99 didn't complete before the timeout value. It appears the INQ dataset got archived after the schedule. In any case, the INQ dataset wasn't available
Resolution
Increase your MAXMOUNTWAIT Config member parameter. It is specified in minutes and can go up to a maximum of 255. The default is 10 minutes.
The period of MAXMOUNTWAIT is not spent LOOPING. The CPU consumption came AFTER the MAXMOUNTWAIT time had expired. Increasing the MAXMOUNTWAIT time will cause XCOM to WAIT longer for the system to provide the necessary resources to continue processing.
