Remote DL/I support is included in CICS® Transaction Server for z/OS®, and works with one of the supported levels of IMS™, (see above for
details of these).
Usually, you use remote DL/I support,
with either MRO or ISC connections, to access databases owned by another CICS region. You can also use CICS remote DL/I support to access, through
another CICS region connected to DBCTL, databases owned by DBCTL. CICS regions accessing
databases owned by DBCTL (that is, connected to DBCTL) must be running on
the same MVS™ image as the DBCTL system. A simple overview is given in Figure 24.
For information about accessing DL/I databases owned by DBCTL, see the CICS IMS Database Control Guide .
To add support in CICS for remote database access, you must:
Code entries in a program specification block directory (PDIR), to indicate the identity of the remote CICS region, or regions, to which you want CICS to function ship DL/I requests. You do this by coding the SYSIDNT parameter in DFHDLPSB TYPE=ENTRY macros, which you assemble and link-edit to create a PDIR. You must also code the MXSSASZ parameter. You can, optionally, code the RMTNAME parameter to define the name by which the PSB is known in the remote CICS region. For information about creating PDIRs, see the CICS Resource Definition Guide .
The following is a summary of the DL/I parameters that you can, or must, code as CICS system initialization parameters:
PDIR={YES|xx} SUFFIX OF PSB DIRECTORY
(MANDATORY for REMOTE DL/I)
PSBCHK={NO|YES} SECURITY CHECK OF REMOTE TERMINAL INITIATING A TRANSACTION
XPSB={YES|name|NO} PSB ENTRIES TO BE CHECKED BY RACF
For details of these (and other) system initialization parameters, see CICS System Definition Guide..
