To avoid any operational issues, a DBA must be aware of the following aspects of the unitymgmt user. This user helps Unity monitor connectivity to the managed Teradata systems.
- This unitymgmt user must be excluded from all backup jobs running on the Teradata system. It has no data to store in backups. Executing a backup on this database can result in locks that block incoming requests and result in an unintended outage.
- The unitymgmt user must be prioritized in the TASM rule set as a high priority tactical user (never queued). Failing to do so could result in database locking issues that lead to unintended outages.
