Back up the metadata in the RDBMS at the same time that you back up the data files in the volume storage locations. A carefully coordinated backup ensures that a one‑to‑one correspondence exists between each entry in the volume metadata database and the data files.
The metadata backup on the RDBMS must be done before the backup of the data files in the volume storage locations. Files that are partially created when the metadata backup begins are either not yet registered in the database or are marked incomplete in the database. The metadata database does not retain a record of incomplete files.
When contacting Actuate Support to troubleshoot problems, it is best to provide a snapshot of the BIRT iHub System configuration, including the following items and information:
A database backup of the cluster and volume metadata schemas
The names of the volume schemas and users that iHub uses to connect to the RDBMS
A copy of the acserverconfig.xml file containing BIRT iHub configuration information
