Using the Db2 Attach feature

The Db2 Attach feature enables you to end the attachment between Catalog Manager and the current SSID, and then establish an attachment to a different SSID on the same z/OS system. You are still able to use all Catalog Manager features.

Db2 Attach has the following requirements:

• Catalog Manager must be installed on the target z/OS system at the same maintenance level as the product instance from which you are connecting.
• The target SSID must be on the same z/OS system as Catalog Manager.
• The Db2 Call Attach Facility (CAF) must be installed.

When you attach to a different subsystem, the installation options and profile that were invoked on your original Catalog Manager session are still in effect. If you make changes to your options while attached to another Db2 subsystem, the changes apply to your original session as well. The following figure shows a current attach and a possible attach of a Catalog Manager session to another Db2 subsystem.
