IBM Tivoli Monitoring, Version 6.3 Fix Pack 2
Enable or disable self-describing agent capability
The self-describing agent environment variable is set to Y to enable the self-describing agent capability on all components by default, with the exception of the hub monitoring server.
The environment variable KMS_SDA is disabled...
KMS_SDA=N
...by default only on the hub monitoring server. All components that connect to the hub monitoring server adjust their self-describing agent function to disabled if the hub monitoring server has the self-describing agent function disabled, or if the hub monitoring server is older and does not support self-describing agents.
This allows control of all self-describing agent enablement from a single point - the hub monitoring server.
A best practice is to only use the KMS_SDA variable at the hub monitoring server to control self-describing agent enablement, but it can be controlled at each component:
Component environment variable Tivoli Enterprise Monitoring Server KMS_SDA Tivoli Enterprise Portal Server TEPS_SDA Self-describing agents TEMA_SDA
You can also use tacmd commands to enable or disable the state of the self-describing agent function at the hub monitoring server, without having to recycle any hub monitoring servers. This control is only applied when the hub Tivoli Enterprise Monitoring Server is configured for self-describing agent capability using the environment variable KMS_SDA=Y.
