I found this sentence in the installation guide:
Important! For OPSVIEW to be fully functional, the OPS/MVS load library must be in a STEPLIB or in the LINKLIST.
For OPSVIEW, I would like to know which function or option, may be not functional if the OPS/MVS load Library is not in the STEPLIB or not in the LINKLIST.
OPSVIEW access will just be about totally useless if the TSO user does not have access to the CA OPS/MVS load library via a STEPLIB or LINKLIST. So, if the library is not accessible, most options of OPSVIEW will fail.
