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
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.
IM and Presence Serviceability > Tools > Service
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.
