Prerequisites
Make sure that the paths to the required system variables are set. Identify a process appropriate for using as a security domain controller. The security domain controller should be a process which is expected to remain running for the life of a metaspace. It is recommended to use
as-agent for this purpose because the overhead of the domain controller is relatively low. Also, in high availability configurations, where more than one controller with identical policy files is used, you can have one
as-agent per system configured as a domain controller.
Note: Remember that a security domain requestor is any client process trying to join a secure metaspace that is not already a security domain controller.
