Preparing to access CICS resources from File Manager

File Manager for z/OS® can access files, transient data queues, or temporary storage queues defined to and owned by a CICS® subsystem.

Installation requirements for accessing CICS resources from File Manager depend on the way in which File Manager is being invoked. File Manager can use FM/CICS to access CICS resources from the following environments:
  • CICS via the ADFzCC server
  • CICS via a batch job
  • TSO/ISPF
  • Batch JCL
  • Eclipse client
CICS via the ADFzCC server
FMN3POPT specifies the option START=TASK, and FM/CICS is run from a CICS terminal via the CICS transaction defined in hlq.SFMNSAM1(FMNCINST). The CICS transaction communicates with the common server via the PORT and, optionally, the HOST address specified in FMN3POPT to spawn an address space to run File Manager that communicates with the CICS transaction via TCP/IP. The spawned address space runs until the FM/CICS session is terminated.

The FM/CICS user interface is an ISPF-like interface which uses the ADFzCC feature called Interactive Panel Viewer (IPV) to display panels under CICS.

See Checklist for installing and customizing File Manager to access CICS resources for the tasks that need to be completed.

CICS via a batch job
FMN3POPT specifies the option START=BATCH, and FM/CICS is run from a CICS terminal via the CICS transaction defined in hlq.SFMNSAM1(FMNCINST). The CICS transaction submits a batch job that executes a procedure based upon sample member hlq.SFMNSAM1(FMN3CICB) that runs File Manager to communicate with the CICS transaction via TCP/IP. The batch job runs until the FM/CICS session is terminated.

The FM/CICS user interface is an ISPF-like interface which uses the ADFzCC feature called Interactive Panel Viewer (IPV) to display panels under CICS.

TSO/ISPF
You can access CICS resources from a File Manager ISPF invocation or keyword from REXX under ISPF. ISPF communicates directly with the CICS region to access its resources.

See Checklist for installing and customizing File Manager to access CICS resources for the tasks that need to be completed.

Batch JCL
You can access CICS resources by executing File Manager from batch JCL.

See Checklist for installing and customizing File Manager to access CICS resources for the tasks that need to be completed.

Eclipse client
You can access CICS resources by invoking File Manager from the Eclipse client.

See Checklist for installing and customizing File Manager to access CICS resources for the tasks that need to be completed.

There are a number of installation steps you need to perform to access CICS resources from File Manager. Some of the steps are common regardless of the environment from which File Manager is invoked, and others are specific to the environment. See Checklist for installing and customizing File Manager to access CICS resources.

Before you can install and customize File Manager to access CICS resources, you must have installed the File Manager base function. These topics assume you have installed File Manager CICS component into the same target and distribution libraries as File Manager base function, with one exception: File Manager CICS load modules are installed by default into FMN.SFMNMOD2, whereas File Manager base function and the other File Manager component load modules are installed into FMN.SFMNMOD1.
