We are looking at applying z14 RSM enhancement PTF UA93213 which includes apar OA51864. This adds " freemained frame" support for high private. http://publibz.boulder.ibm.com/zoslib/pdf/OA51864.pdf
On a z13 z/OS V2R2, RSM had support for " freemained frame" for low private. This caused " Applications that issue the TPROT instruction or reference storage that was freemained will not always get a condition code of 3 or an 0C4 system abend". The solution was to use VSMLOC and VSMLIST services as alternatives to TPROT or use the IARBRVER and IARBRVEA services which are higher performance callable services that provided the same results as TPROT. Does anyone have this enhancement on with their z14's ? I would assume that vendors fixed their code for z13 support for "freemain frame" support that they fixed in in all their code for both low and high private ? I understand that we could turn off this support with a DIAG but then we would lose the performance benefit of the enhancement.
