Defining a CTC physical link

CTC links are usually used only when the IMS systems are in the same data center. You can assign only one logical link to a physical link that uses the CTC connection type.

You can use either the CREATE MSPLINK type-2 command or the MSPLINK stage-1 system definition macro to define the physical link and its attributes.

To use the CREATE MSPLINK command, dynamic resource definition must be enabled in your IMS system. The CREATE MSPLINK command is logged.

If dynamic definition is not enabled in your IMS system, you must use the MSPLINK macro to define your physical links. During system definition, define all physical connections that might potentially be used, even if several might be for backup purposes or might not be intended for continual use.

For CTC links, you must add an address parameter value. Each CTC link must have a unique address.

If you create a CTC link by using the MSPLINK system definition macro, you must also add a DD name.
