Changing the location of data files

You can change the location of the data folder, which contains data files created by Cognos Analytics components.

The default location of this folder is installation_location/data

Important: The data folder must reside locally on the active Content Manager computer as well as on each standby Content Manager computer.

If you specify that data files reside on a shared network drive, then the active and standby Content Manager computers will try to access the same Search Index files in the data/search folder. As a result, users will see this message:

Unable to retrieve activities at this time. ADM-ERR-001

In addition, error messages will be logged and the index may get corrupted. Here is an example of a logged error message caused by the data folder being configured on a shared disk: Already closed: MMapIndexInput(path="\\myshare\cognos11\data\search\collections\cm\data\index\_c0d_Lucene50_0.tim") at ~[lucene-core-8.2.0.jar:8.2.0 31d7ec7bbfdcd2c4cc61d9d35e962165410b65fe - ivera - 2021-04-19 15:05:56]
