Issue/Introduction

Question:

If the ITKSTC started task needs to be restarted with option "COLD" (e.g. after applying maintenance to the IMS tools loadlib), all IMS control regions which are connected to this ITKSTC region, also need to be recycled (stopped/re-started).

Answer:

To identify which IMS control regions actually need to be recycled, use this MODIFY operator command to display all IMS control regions which are currently connected to ITKSTC :

/F ITKSTC,DIS ACTIVE

Note 1 - "ITKSTC" is the standard name of the IMS tools started task (your name can be different)
Note 2 - issue this MODIFY command before stopping the started task
