This document discusses the new Default Cache feature in Cisco Information Server (CIS) Version 7.0.2 and later.
There is no Default Cache feature present on my Version 7.0.2 server.
If you patched your CIS instance up to v7.0.2 (SP-2) from v7.0.1 or earlier, you might not see the "/lib/sources/defaultCacheDataSource" resource or see the checkbox option "Use Default Cache Database" in a resource's Caching tab.
The reason is likely that you have not yet manually run the /bin/cis_upgrade_patch.sh (.bat if on Microsoft Windows) script after installation of the SP-2 level hotfix. This script enables this new caching feature and deploys an additional local Postgres instance dedicated as the cache target platform. This new cache feature combines the ease of use as with the legacy "Automatic" (file) mode cache, but utilizes three relational tables for a multi-table style cache target.
Note: This script is not to be confused with the earlier /bin/update_patch.sh file (.bat if on Microsoft Windows) that you might have used in prior SP upgrades. The use of this file has been deprecated in v7.0.2 and later, but the file might still be present from earlier hotfix installs.
If your v7.0.x instance was created from a v7.0.2 installer build, then the Default Cache should never be missing, as it is automatically configured in the installation process.
