The following information contains guidance about parameters that are important in the definition of remote data resources that are to be accessed by function shipping. Those data resources are:

  • Remote files
  • Remote transient data queues
  • Remote temporary storage queues

Reference IBM:

Defining remote files:

A remote file is a file that resides on another region. CICS uses function shipping for file control requests that are made against a remote file.

CICS application programs can name a remote region explicitly on file control requests by means of the SYSID option. If this is done, you need not define the remote file in the local region.

More generally, however, applications are designed to access files without being aware of their location, and in this case you must define the remote file in the local File Definitions (FD) entry.

Note:
The definition of the file in the system that is named in the SYSID parameter can itself be a remote definition.

Defining remote transient data queues:

A remote transient data queue is one that resides on another region. CICS uses function shipping for transient data requests that are made against a remote queue.

CICS application programs can use the SYSID option to name a remote region explicitly on transient data requests. If this is done, you do not need to define the remote transient data queue on the local region.

More generally, however, applications are designed to access transient data queues without being aware of their location, and in this case you must define the remote queue in the local Transient Data Definitions (TDD).

Defining remote temporary storage queues:

CICS application programs use temporary storage queues to store data for later retrieval. A remote temporary storage queue is one that resides on another region. CICS uses function shipping for temporary storage requests that are made against a remote queue.

CICS application programs can use the SYSID option to name a remote region explicitly on temporary storage requests. If this is done, you need not define the remote temporary storage queue on the local region.

More generally, however, applications are designed to access temporary storage queues without being aware of their location, and in this case you must define the remote queue in the local Temporary Storage Definitions (TSD).
