Release : 11.0
Component : CA-11
The U/2700 abend is an indication that the Mant task had a problem. The SVC99 R15=0004 S99ERROR=0210 reason and return codes indicate that the dataset is already in use. Messages similar to the following will also appear in the CA 11 joblog.
IKJ56225I DATA SET CAI.CA11.PURGE.FILE ALREADY IN USE,
IKJ56225I DATA SET IS ALLOCATED TO ANOTHER JOB OR USER
This can occur in instances when more than one CA 11 is attempting to run the Mant task at the same time against the same database. If you have more than one CA 11 in a sysplex and they use the same Datacom/AD MUF, only one of those CA 11 can run the Mant task and that is the one residing on the same LPAR as the Datacom/AD MUF. The other CA 11's will need to have MAINTTME=0 specified in the config file.
