    IMS SINGLE TCB per TMEMBER BOTTLENECK

    The current IMS design has a single TCB per TMEMBER, resulting in bottlenecks once transaction volume approaches the critical limit (which is unknown at this time). While IMS performance testing has shown IMS can handle 100K trxs per second, the b...

    Dynamic calculation of YTIB and TPIPE limits according storage available

    IMS should enhancement the TPIPEs and YTIBs blocks allocation, calculating dynamically the limit to be created according the amount of extended private available. This could be by client choice, for example, setting a parameter MAXTP=MAX instead M...

    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.
