DUMP view

This tabular view displays the virtual storage for an IBM CICS region or the BBI-SS PAS that controls the target in the context. You must be in target mode to display this view.

PK is an alias for the DUMP view.

To display the contents of CICS virtual storage, issue one of the following commands:

DUMP or PK

The following figure is displayed:

Usage notes

  • You do not have to shut the system down or take a snap dump before displaying virtual storage with the DUMP view.
  • The DUMP view allows you to display virtual storage from the following sources:
    • CICS region
    • BBI-SS PAS

  • The Block/Table name field contains the name of a block that you want to view. You can use this field to select and examine CICS control blocks such as FCT or PPT entries. When displaying CICS control blocks, prefix the name of the block with DFH. Some control blocks, such as the FCT entries, can accept additional input such as DFHFCT filename.

    The Block/Table name field also supports finding the load or entry point for programs loaded by CICS using the command CPROG pgmname to identify a program. To find the entry point, use the command CPROGE pgmname.

    See the online help for a list of named control blocks supported by the DUMP command.

  • The value in the offset field provides an offset into the block specified in the Block/Table field.
  • The Job/STC field provides the job or STC name of the address space whose storage the view displays. The value in this field defaults to the name of the BBI-SS PAS that controls the target in the context when you enter the DUMP command. If you hyperlink to this view, the field defaults to the target name of the context.
  • The Hex ASID field provides the hexadecimal ID of the address space (ASID).
  • The Hex Address field provides the 64-bit address of storage.
  • You can navigate to other addresses by entering one of the following hyperlink action characters followed by an address, and pressing Enter:
    • an exclamation mark (!) to hyperlink to a 64-bit address: !address
    • a question mark (?) to hyperlink to a 31-bit address: ?address
    • a percentage sign (%) to hyperlink to a 24-bit address: %address
  • You can also use any of the following three fixed hyperlinks in the fixed section to navigate through the stack of storage displays:
    • Back returns to the previous storage display in the stack.
    • Fwd moves forward to the next storage display in the stack.
    • Clear clears all storage displays in the stack (and the current entry remains).
Warning

Because of the implications of being able to view storage, which might contain sensitive business information, you should carefully consider who is granted user access to the DUMP view.
