DFS0565I cccc COMMAND NOT PROCESSED DB=xxxxxxxx IN USE BY PSB=psbname, REG=region-number
Explanation
The named DL/I database, xxxxxxxx, cannot be processed in response to a /DBDUMP, /DBRECOVERY, or /START command. It is still in use by an active batch message processing program.
region-number is the number of the region in which a program is using database xxxxxxxx.
The MPP region identified in this message can occur to break a potential deadlock condition between Online Change, a DBR or STA command against a database being used by the MPP, and an application running in the MPP issuing an ICMD or CMD call.
System action
The command is not processed for the database named in the message, but processing continues for any other databases specified in the command.
If the NOFEOV keyword is not specified on /DBR or /DBD, a new log volume is mounted.
If /DBD or /DBR is entered, a simple checkpoint is taken.
Operator response
Wait for the program to terminate, and reissue the /DBDUMP, /DBRECOVERY, or /START command
