While testing i found below issue while accessing OPSVIEW panel- Option 6 Command:
Cannot find program OP600000 in SYSEXEC
Other possible message if the DD SYSEXEC is not even allocated to the TSO session:
Cannot find program OP600000 SYSEXEC DDNAME is not allocated
Release:
Component: OPSMVS
Make sure you have the CA OPS/MVS CCLXEXEC library allocated in the SYSEXEC concatenation of your TSO session. It has to be SYSEXEC, LIBDEFs are not allowed for this library
