DL/1 PCB List (5.4.2)

The DL/1 PCB List screen (5.4.2) allows you to view a list of DL/I PCBs in a PSB. A PCB defines the segments in a DL/I database that can be accessed, and the type of access that can occur. Throughout the DL/I (5.4) functions of Code Debug CICS, a DBD is associated with a PCB. Access a DL/I database via a PCB number (the number displayed prior to the DBD name). The list is displayed in the order that the PCBs have been defined in the PSB.

To position in the list, use the UP, DOWN, TOP, BOTTOM, and LOCATE commands.

Access this screen by typing the number 4.2 on the File-Utility-Menu-5, typing 2 on the DL-1-Database-Menu-5-4, or as described in Transferring Between Screens.

Input Fields

SEL

Enter S to select a PCB for further processing via the DL-1-Segment-List-5-4-3 screen.

PSBNAME

Use the PSB to define a set of DL/I databases that can be accessed from a program. When a PSB name is selected from the DL-1-PSB-List-5-4-1 screen, Code Debug CICS automatically displays it in this field. You can also enter a valid PSB name in this field. Code Debug CICS checks the PSB name and displays an error message if it is invalid for the CICS region or the DBCTL region to which this CICS region is connected. Always select a PSB to access a DL/I database.

Output Fields

DBCTL STATUS

Displays the status of DBCTL in this CICS region.

DBCTL ID

Displays the ID of the DBCTL region to which this CICS region is connected.

PCB#

Number of a PCB that was selected on the .DL/1 PCB List (5.4.2) v17.02 screen. Code Debug CICS uses this number to identify which PCB to use to access a DL/I database from the selected PSB. Code Debug CICS uses the PCB number instead of the DBD name because multiple PCBs can access the same DBD using the same or slightly different views of the database.

DBD

Name of the DBD that defines the database associated with a PCB.
