How RESLEVEL can affect the checks made

Depending on how you set up your RESLEVEL profile, we can change which user IDs are checked when access to a resource is requested. The possible checks are:

• Check the IMS region address space user ID and the second user ID or alternate user ID.

• Check IMS region address space user ID only.

• Do not check any user IDs.

The following table shows the checks made for IMS connections.
