Turning on this option can degrade IM performance. Because all inbound messages are already logged, do not enable this setting unless you are using IM compliance in intercluster or federated networks.
For each node, assign a database from the External Database option.
If you are using one external database for your cluster, assign all nodes to the same external database. If you are using more than one external database for your cluster, assign the nodes to the external databases based on your capacity requirements.
Start the Cisco Message Archiver service (if this service is not already started).
Restart the Cisco XCP Router.
If you make any subsequent changes to the Message Archiver configuration, restart the Cisco XCP Router Service.
(All releases) If you switch between IM compliance deployment options (for example, switch from the Third-Party Compliance Server option to the Message Archiver option), you must restart the Cisco XCP Router Service.
The Cisco XCP Message Archiver service must be running for the compliance feature to operate correctly on IM and Presence.
If you do not assign an external database to a node for the compliance feature, IM and Presence does not permit you to turn on the Cisco XCP Message Archiver service.
Select Cisco Unified IM and Presence Serviceability > Tools > Service Activation.
Select the server from the Server list box.
Select the radio button next to the Cisco XCP Message Archiver service in the IM and Presence Services section.
If the Cisco XCP Message Archiver service fails to start, but the System Troubleshooter (Cisco Unified CM IM and Presence Administration > Diagnostics > System Troubleshooter) shows that the status of the external database connection is ok, we recommend that you unassign the external database from the node, and reassign it again.
