Expedite the OTMA ACEE cleanup

Some IMS customers have many cached OTMA ACEEs for RACF userids. Searching through hash synonym chains for OTMA ACEEs is using much CPU. The number of hash chains should be increased from the current 509. Also – if the ACEEs were chained in ascend...

Moving LSAVs into OTMA ITASK block itself for removing any storage management overhead

Add the 20 save areas into the main OTMA ITASK block DSECT, for example DFSYQAB. Get the one block, chain its save areas together, and then pass SA1 to DFSCIR. This will get rid of LSAVs and the DFSBCB GET for save areas all together.
