We are looking at V12 of DB2. DB2 V12 has a requirement of setting NON_VSAM_XTIOT=YES in DEVSUPxx and am wondering if any issue with MAT.
More info from IBM:
Examine programs that call dynamic allocation, issue RDJFCB, or open
datasets which might have been dynamically allocated with the XTIOT
(extended TASK INPUT/OUTPUT table), UCB nocapture, and
DSAB-above-the-line options of dyna location, to see if they require
updates. As appropriate, modify the programs and specify the DCBE
option LOC=ANY to signify that the programs support the XTIOT,
UCB nocapture and DSAB-ABOVE THE LINE options of dynamic
allocation, or that they are not impacted by the support.
