There is an activity in our organization to migrate the existing OS environment from RHEL 6.5 to RHEL 8.6. All the old solution have NetBackup agent configured and backups were running smoothly. We provided the team with fresh OS (RHEL 8.6) and configured the NetBackup Client (9.0). Instance registered with ORACLE & OS credentials. Now, the Database backups are failing with status code 1 while all the file level backups are healthy.
