264 VLDB 2012 Track All DB2 Address Spaces Real and Virtual Storage in IFCID 225

With DB2 Ver 10 ECSA consumption has shifted from DB2 DIST address space to the DB2 MSTR address space. This is thread related storage and increases as the number of active DBAT connections increases. There is a need to track this for each individual DB2 member as we scale up DB2 with more data base connections and yet try to fit within the defined ECSA of an LPAR.

We also need to track the occurrence of memory leaks in DB2 MSTR ECSA in such a way that we can have DB2 PM or some other interface to automation alert us. We have already experienced a DB2 MSTR ECSA leak in V10.

Today only DB2 DIST and DB2 DBM1 have their ECSA consumption recorded in IFCID 225. So to begin with we need DB2 MSTR ECSA usage tracked in IFCID 225.

Carrying this request to it's logical conclusion we need the real and virtual storage of all DB2 address spaces including DBM1, MSTR, DIST, IRLM, WLM Stored Procedure MSTR and Servers, and those yet to be invented tracked in IFCID 225.

    Thank you for submitting this enhancement request. While we view all the enhancement requests we receive as valuable and we would like to implement all of them, in an effort to have maximum transparency we are closing the ones that don’t currently appear on our two year product roadmap. This is not to say that these enhancements may not still be implemented at some point in the future as we do evaluate our requirements on the basis of customer demand and technical impact, to deliver maximum value to our customers.

    We appreciate your input to the Db2 for z/OS development team.  And we hope that you will continue to submit enhancement suggestions for improvements as customer feedback is a key component to shaping the future direction of Db2 for z/OS.
