Chapter 3: User Scenarios
The following user scenarios refer to the CMS servers as “Primary” and
“Secondary”. You should perform your day-to-day administrative
functions on the Primary CMS server and use the Secondary CMS server
only when the Primary is down. These user scenarios describe how to
perform normal CMS tasks in your High Availability configuration so that
the CMS servers are kept synchronized.
Agent Trace -
Modification
3
For maximum reliability, it is recommended that you initiate all Agent
Traces on both the Primary and Secondary CMS servers. This will
ensure that there is a backup for the Agent Trace information in case one
of the servers goes down.
1. Access the
Agent Administration: Activate Agent Trace window on
the Primary CMS server.
2. Modify the trace on the Primary CMS server.
3. Access the
Agent Administration: Activate Agent Trace window on
the Secondary CMS server.
4. Modify the trace on the Secondary CMS server.
Base Load
Upgrades with
High Availability
3
When a CMS base load upgrade is performed on High Availability (HA)
systems, the upgrade procedure can be performed in a manner that
avoids system downtime and synchronizes data between the two HA
servers.
For a description of the procedure used to perform a base load upgrade
on CMS HA systems, see “
CMS Base Load Upgrade Procedure for High
Availability Systems”.
