Description
The XDMSSN parameter is available only for z/OS with CRAM-XDM.
The XDMSSN parameter passes a z/OS secondary subsystem name that overrides the value stored in the CRAM IGCLM244 module. That value, a maximum of four characters, is initially specified during CRAM installation.
Example: XDMSSN=SS03
On the client side, the XDMSSN parameter applies to the following IODEV threads and can be in the form:
subsystem:channel
where subsystem is a 4-character name, separated by a colon (:) from channel, which is an 8-character name.
| IODEV thread | Example or discussion |
|---|---|
| 11 | TSO: CALL ’DSN(M204FS)’ ’M204:M204FULL’ CICS: M204 M204:M204FULL DATA logon superkluge |
| 13 | Passed as part of the SQLConnect CLI function call via server name |
| 23 | Passed as part of the IFSTRTN |
| 29 | Passed as part of the IFDIALN HLI via the CHAN parameter and Batch2 |
The subsystem name stored in IGCLM244 can also be overridden by BATCH2 or IFAM2 jobs as shown in the following examples:
- Program Communication facilities:
//BATCH2 EXEC PGM=BATCH2,PARM='[ssn:channel][,[OMC={Xhh | ddd}] [,URCTYPE={N | O | B}]]'
- IFSTRTN (IFAM2) (HLI function):
IFSTRTN|IFSTRN (RETCODE,LANG_IND,LOGIN,THRD_TYP,THRD_ID,[SSN:]CHAN)
- IFDIALN (HLI function):
IFDIALN|IFDILN (RETCODE,LANG_IND,[SSN:]CHAN,BUFFER,IO_LEN)
