Control blocks

Figure 70 illustrates some of the control blocks used to support remote DL/I.

Figure 70. Some control blocks used for remote DL/I support
 CSADLI, the DL/I interface entry, points to DLP, the DL/I interface parameter list. DLP includes DLPDLI (entry point for DFHDLI), DLPEDPEP (entry point for DFHEDP), DLPRPEP (entry point for DFHDLIRP), and DLPRPDIR, which points to PDIR, the remote PSB directory. TCARSBA, the DBCTL remote scheduling block address, points to RSB, the remote scheduling block.

The DL/I interface parameter list (DLP) is described in DL/I interface parameter list (DLP).

The remote PSB directory (PDIR) contains an entry for each remote PSB that can be used from an application program.

The remote scheduling block (RSB) is acquired when a CICS® task issues a PSB schedule request for a remote PSB. The RSB is freed when the task issues a SYNCPOINT or a DLI TERM request.

See CICS Data Areas for a detailed description of these control blocks.
