CONNX for CICS/VSAM supports CICS remote file access for VSAM Key-Sequenced Data Sets (KSDS). When two or more CICS regions are configured to communicate using either intersystem communication (ISC) or multiregion operation (MRO), the CONNX CICS / VSAM programs installed on one CICS region can access CICS remote files defined on separate CICS regions.  

Example:

CONNX for CICS/VSAM is installed on region CICS. An MRO link is defined to another region, CICSBETA, which is started on the same OS/390 system. Two instances of the CONNX sample VSAM KSDS Customer file are defined on region CICS; the first (CNXCSTK) is local; the second (CNXCSTX) is remote and refers to a copy of the CNXCSTK file defined on region CICSBETA.

Remote File Definition

The screen shot below demonstrates how the remote file CNXCSTX is defined to the local CICS RDO file:




The remote attributes map file CNXCSTX to file CNXCSTK on remote system CICB, which is defined as an MRO link to region CICSBETA:
