Upon activating the OPSWEB STC the failure screen is shown with message:
Current processing status: FAILURES
This is what happened during initialization:
N85723 AOM START FAILED, REASON, SUBREASON 003-003.
N85724 DESC: SSI (SSAB) SETUP FAILED, RC: NO SSCT FOUND
NetMaster tried to initialize /PARM group OPSYSIDS--but could not find
(AOM) SSID=OPER defined on the system.
From the online help of N85724 (for 003-003):
003 SSI (SSAB) SETUP FAILED. RC: reason
SSAB is the NetMaster SubSystem Anchor Block. There is one SSAB for each
SSI acquired by NetMaster, pointed to by the operating system SSCT (Sub-
System Communications vector Table) for the SSI. When AOM attempt-
ed to perform SSI setup, an error occurred. The following errors
NO SSCT FOUND (SSID BAD). The supplied AOMSSID cannot be
found. Possibly, it is misspelt, or not in the subsystem definition
member (for example, IEFSSNnn on MVS systems).
The OPER subsystem was created dynamically and the problem was resolved.
