UCMDB Support Tip: uCMDB History Database Purging and Maintenance mechanism

For optimal performance and history database application maintenance, the Database Administrator should review the database guide for the respective database used by UCMDB Application. There is comprehensive information available about database settings and maintenance. It is important that database application should comply with the information provided in the database guide.
