This parameter specifies the location where the contact information used for notification by the Scheduler and the Health Monitor is stored.
The location is defined to be a DB2 administration server's TCP/IP hostname. Allowing contact_host to be located on a remote DAS provides support for sharing a contact list across multiple DB2 administration servers. If contact_host is not specified, the DAS assumes the contact information is local.
This parameter can only be updated from a Version 8 command line processor (CLP).
