I need to add new instance of CA 7. Is there a way to add this instance dynamically without GLOBAL DELETE + GLOBAL INIT?
Yes, you can add an new CA 7 instance without having to perform a GLOBAL DELETE + GLOBAL INIT. All you need is to run CAIRIM with only a CA 7 statement in the RIMPARM and L2OPTS input as such:
//L2OPTS DD *
CA7x ADD [options]

As always, please contact CA Technologies support for CA 7 if you have further questions.
