(Dist) serverQuiesce.py script

Use the serverQuiesce.py script to decrease workload to a SIP container over an interval, and optionally stop the server. We can also cancel the quiesce during a set time interval if certain conditions are met.

With this script, we can gradually decrease workload to a SIP container over an interval. We can also optionally stop the server.

(ZOS) Restriction: Intelligent Management does not support SIP features on the z/OS operating system.

The serverQuiesce.py script is located in the app_server_root/bin directory.

Run the following command.

./wsadmin.sh -f serverQuiesce.py <operation> [options]

Replace the <operation> and [options] variables with the appropriate operation and options for our task.
