A user encountered the error OPS1423E while attempting to access the OPSLOG via the OPS/MVS OB (OPSVIEW Browser).
The OPS1423E message is written when the OPS/MVS security exit denies the current user access to the OPSLOG.
The OPS1423E error is triggered when the OPS/MVS security exit determines that the current user ID does not have the required access to the OPSLOG at that moment. Security implementation depends on your system configuration, which can be verified via the EXTSECURITY parameter:
External Security (ESM): If the EXTSECURITY parameter is set to ON, OPS/MVS delegates security checks to your External Security Manager (e.g., RACF, ACF2, or Top Secret).
Internal AOF Security Rules: If the EXTSECURITY parameter is set to OFF, security is managed via OPS/MVS Automation Object Facility (AOF) security rules.
Additional Troubleshooting If the issue is intermittent and resolves after re-logging in, verify if there was a temporary issue with the user's security session or context at the time of the failure. If the error persists, monitor OPSLOG and Security Audit events to track denied access attempts in real time.
