You can suspend and resume the self-describing capability for your environment by using the tacmd suspendSda and tacmd resumeSda commands without having to recycle the monitoring server. You can suspend the self-describing capability for various reasons such as, when modifying the self-describing installation options or when going into maintenance mode.
The tacmd suspendSda and tacmd resumeSda commands dynamically change the self-describing behavior only when the hub monitoring server is configured with KMS_SDA=Y. Issuing the tacmd suspendSda and tacmd resumeSda commands will not override the KMS_SDA=N setting. If the tacmd resumeSda command is issued when KMS_SDA=N, the command is ignored until KMS_SDA=Y.
Issuing either the tacmd suspendSda or tacmd resumeSda commands updates the TAPPLPROPS table. This setting is saved regardless of the KMS_SDA setting. Best practice is to set the hub monitoring server environment variable to KMS_SDA=Y, then run the tacmd suspendSda or tacmd resumeSda commands.
