IBM Tivoli Monitoring, Version 6.3 Fix Pack 2
Agents
Coexistence and interoperability statements for Agents.
IBM Tivoli Monitoring V6.3 agents (and application agents using the V6.3 agent monitoring framework) require a V6.3 Tivoli Enterprise Monitoring Server and Tivoli Enterprise Portal Server. In other words, the V6.2.3 (and earlier) monitoring server and portal server do not support V6.3 agents.
Pre-V6.3 agents cannot coexist on the same machine as V6.3 Tivoli Monitoring server components, and must be upgraded at the same time as the V6.3 Tivoli Monitoring server components.
Back-level agents can connect through up-level monitoring servers. In particular, V6.2.1 agents will work with the V6.2.1, V6.2.2, V6.2.3, and V6.3 Tivoli Enterprise Monitoring Server and Tivoli Enterprise Portal Server.
Agents that use dynamic affinity cannot connect or fail over to a pre-V6.2.1 remote monitoring server.
An agent upgrade elevates the user credentials of agents that have been set at deployment time to run with reduced (non-root) credentials. Use one of the following steps to stop the agent and restart it with the appropriate user credentials:
- After stopping the agent, log in (or invoke su) as the desired user, and then run the itmcmd command to start the agent in that user's context.
- Edit the startup file, and add the following line to change the default user context for starting agents:
/usr/bin/su - dbinstancename-c "itmhome/bin/itmcmd agent -h itmhome -o dbinstancename start product_codewhere:
- product_code
- is the two-character product code for the agent (for example, ud for DB2 for Linux, UNIX, and Windows).
The Tivoli Monitoring Universal Agent and Tivoli Monitoring UNIX Log Alert Agent are no longer provided with IBM Tivoli Monitoring V6.3. The V6.1.x and V6.2.x versions of those agents will continue to connect to V6.3 monitoring servers.
