db2adutl performance

When we are deleting logs in TSM every week, we encounter very poor

performance for deleting > 1000 logs for each DB2 partition. There

are 131 DB2 partitions. Deleting the same amount of logs with dsmc del .

. . . . works much faster. We assume db2adutl deletes log by log

sequentially per DB2 partition. The command is "delete logs older than

<logfile> db <db> dbpartitionnum X without prompting" We

call db2adutl with db2_all per single DB2 partition in configurable

chunks (8 - 16 DB2 partitions in parallel)"

Wanted to know if db2adutl can be multi threaded and can do this operation in parallel?

    This idea will look at changing the way we do delete from one by one to batching as many as the TSM server allows.

    If this is not adequate then we will have to look to idea https://bigblue.aha.io/ideas/ideas/DB24LUW-I-994
