Permanent Sysplex Variables created with OPSVASRV function couldn't be backed up to VSAM datasets.
CSV463I NO MODULES ARE ASSOCIATED WITH EXIT CA_VARDATA_CHG
Issue the following command to display the dynamic exit used by the CAVARSRV component :
D PROG,EXIT,EXITNAME=CA_VARDATA_CHG,DIAG
if the response is
CSV463I NO MODULES ARE ASSOCIATED WITH EXIT CA_VARDATA_CHG
then
Set the GLVNOTIFYRULES OPS parm to YES from OPSVIEW 4.1.1 and issue the following command:
/F OPSS,RELOAD(OPVASREX)
Reissue the D PROG,EXIT,EXITNAME=CA_VARDATA_CHG,DIAG command.
You should now see the OPVASREX module associated with the exit.
Try to update or create a new GLVPLXP variable and see if it's written to the VSAM file.
