Hi, this is quite a long mail, thus be patience.

Can anybody share with me how can I gain access to CICS resources from the OS/390 USS application daemon and vise versa.

I have read through the some IBM manuals and the solution to this, is to make use of the CICS External Interface (EXCI) feature and also involve some IRC (Interregion Communication) configuration. To this, I have implemented the IBM sample application which documented in Chapter 3.7 of CICS External Interface Guide. But the problem is, I am not able to get the CICS IRC OPEN. This is what I got from the CICS log whenever I tried to SET IRC OPEN.

DFHIR3780 DEVCICS Unable to start interregion communication. Return code=X'000000D8', Reason code=X'00000004'

DFHME0116 DEVCICS

(Module:DFHMEME) CICS symptom string for message DFHIR3780 is PIDS/565501800 LVLS/530 MS/DFHIR3780 RIDS/DFHAPATT

I have no idea what the symptom string was in message DFHME0116. However, I have reported this to the local IBM support as per recommendation from the manual. Whereas for message DFHIR3780, I have ensure the following requirement are satisfied as stated in the manual.

1. DFHIRP has already defined in the MVS link pack area (LPA). Verified via "D PROG, LPA" command.
2. CICS has already defined as an operating system subsystem. The uniqe subsystem name is DEVC.
3. The XCF??? Not application.
4. The userid of the CICS job is authorized to log on to the CICS interregion program (DFHIRP) using the generic applid specified. Racf command are,

permit DFHAPPL.DEVCICS CLASS(FACILITY) ID(STARTU) ACCESS(READ)
rdefine facility (DFHAPPL.DEVCICS) UACC(NONE)

5.The CICS region has a unique generic applid named DEVCICS.
6. Sample CICS group DFH$EXCI & DFH$FILA have already installed using RDO.

What else could I miss out ??


P/S:
a) CICS and USS are running within the same box.
b) CICS is a started task.
c) The sample non-CICS program which provided by IBM, is written in C (DFH$DXCC). It is responsible to make calls to CICS resources through EXCI.

To my knowledge, you are not allowed to change the name of the subsystem.
It is supposed to be CICS. The x'D8' may be found in the Data Areas manual
under the IRC entry. It is IRERRENV - Subsystem notification error (MVS
only).
