Managing the backup and recovery of Encyclopedia volume metadata and data files
A complete Encyclopedia volume backup must include the following items:
A database backup of the Encyclopedia volume schema containing the metadata
A copy of the folders from all Encyclopedia volume disk partitions containing file data
A copy of the acserverconfig.xml file containing iHub configuration information
In the Windows BIRT iHub environment, the default AC_SERVER_HOME path is:
C:\Program Files (x86)\Actuate\iHub2
The default AC_DATA_HOME path is:
C:\Actuate\iHub\data
The default Encyclopedia volume path is:
C:\Actuate\iHub\data\encyc
The default acserverconfig.xml file path is:
C:\Actuate\iHub\data\config\iHub2
Back up the Encyclopedia volume metadata in the RDBMS at the same time that you back up the disk partition data files. 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 Encyclopedia volume metadata backup on the RDBMS must be done before the backup of the data on the disk partitions. 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 Encyclopedia volume configuration, including the following items and information:
A database backup of the Encyclopedia volume schema containing the metadata
The name of the Encyclopedia volume schema and user that iHub uses to connect to the RDBMS
A copy of the acserverconfig.xml file containing iHub configuration information
A copy of the iHub logs
