Is there a better way to set up the BMP environment for the FMP for IMS, other than as follows?
IMS has the following Dynamic allocation for ACBLIB
File Master for IMS has the following for the BMP environment
ACBLIB #1 ===> 'IMST.ACBLIBF'
#2 ===> __________________
#3 ===> __________________
DOPT ACBLIB ===> 'IMST.IXP.ACBLIB'
DBDLIB #1 ===> 'IMST.DBDLIB'
We have a automatic process that perform an IMS online change (/MODIFY PREPARE + /MODIIFY COMMIT) every 15 minutes along the day. In rare occasions, we faced the message
DFS3488 ERROR DURING ENQUEUE FOR DDNAME IMSACBx
What we have realized by researching the log is this message DFS3488 when occurs, always there is someone using the File Master in the BMP environment listed above.
What we think is IMST.IXP.ACBLIB is causing the contention. FMP for IMS allocates the IMST.IXP.ACBLIB to build the dynamic ACB while IMS is trying to perform the online change for ACBLIB.
