A CA/MAT measurement of a production CICS system shows ICVBTGGC CSECT of VPEHJN71 module as the top issuer of EXEC CICS GETMAIN requests. Is it correct? Is there any way to reduce the number of these GETMAINs?
Release : 15.1
Component : CA IDEAL
All the IPC GETMAIN requests are routed through that routine (ICVBTGGC) as it's the VPE storage interface to CICS.
The excessive/incorrect use of RELEASE PROGRAM in Ideal can force storage to be repeatedly released and re-acquired. This is often done as a quick but incorrect way to re-initialize data areas.
