Content maintenance tasks can check for inconsistencies within the content store due to missing data or obsolete data or between the content store and external namespaces.
Missing data within the content store may cause updates to fail. Obsolete data may prevent you from creating new objects. When a content store maintenance task fixes the content store, it adds default values for the missing data, which you can update later. It also permanently deletes any obsolete data. To ensure that you do not lose any data that you wanted to keep, we recommend that you choose the find mode first and check the results before fixing the content store.
When you find and fix the data, the content store is not fixed while the content maintenance task is running. Instead, Content Manager fixes the inconsistencies in the content store the next time it starts up.
Important: After you run a content maintenance task to find and fix the content store, back up your content store before you restart Content Manager.
We recommend that you perform internal maintenance checks regularly, but it is particularly important to do so before you upgrade, to ensure the consistency of the content stores.
When you delete users in external namespaces using a third-party
authentication provider, user account information remains in the
content store. You can use the Cognos Administration to find user
information that still exists in the content store and fix the content
store by deleting any users that do not exist in your external namespaces.
You can also delete individual user profiles from the content stores .
If you want to run a content maintenance task on more than one namespace, do one of the following:
If you want to run the content maintenance task now, simply log on to the namespaces and create the content maintenance task.
If you want to schedule a content maintenance task to run in the future or on a recurring basis, keep in mind that a scheduled content maintenance task runs against the namespaces that you select when you create the content maintenance task. Before you schedule a content maintenance task, ensure that your credentials contain logon information for each namespace by renewing the credentials after you log on to every namespace that you select to run the content maintenance task against.
Tip: Click My Area, My Preferences, click the Personal tab, and then click Renew the credentials.
You must have logon permission for each selected external namespace and read permission for all user accounts on each external namespace.
If you do not have read permission for a user account on the external namespace, it is assumed that the user was deleted from the namespace. When you run a content maintenance job, the user information on the content store is either listed as inconsistent (for find) or automatically deleted (for find and fix).
You must have the required permissions to access Cognos Administration functionality. See Secured Functions and Features.
