Customized contents using the SDATA parameter

The IBM-supplied default contents and the contents available through customization are detailed in Table 1. The tables show dump contents alphabetically by the parameters that specify the areas in the dumps. Before requesting a dump, decide what areas will be used to diagnose potential errors. Find the areas in the tables. The symbols in columns under the dump indicate how the area can be obtained in that dump. The symbols are:
C
Available on the command that requests the dump
D
IBM-supplied default contents
M
Available on the macro that requests the dump
P
Available in the parmlib member that controls the dump options
X
Available on the CHNGDUMP operator command that changes the options for the dump type
blank
No symbol indicates that the area cannot be obtained.
Note: System operator commands and assembler macros use the parameters in the table to specify dump contents.

The order of the symbols in the following table is not important.

Start of changeThe following table describes how HCSAByASID, HCSANoOwner, and HCSASysOwner affect the CSA storage that is captured in an SVC dump:
Table 2. Affects on the CSA storage captured in an SVC dump
Specified SDATA option or options CSA storage that is included in the dump
CSA All above the bar and below the bar CSA storage
CSA, HCSAByASID, HCSANoOwner, HCSASysOwner All below the bar CSA storage, high virtual CSA storage that is owned by the ASIDs that are included in the dump, high virtual CSA storage for which the owner has ended, and high virtual CSA storage that belongs to the SYSTEM.

The dump does not include high virtual CSA storage that is owned by the ASIDs that are excluded from the dump.
HCSAByASID, HCSANoOwner, HCSASysOwner All high virtual CSA storage that is owned by the ASIDs that are included in the dump, high virtual CSA storage for which the owner has ended, and high virtual CSA storage that belongs to the SYSTEM

No below the bar CSA storage is included in the dump.
(Neither CSA nor any of the HCSAxxxx options) None of the CSA storage is included in the dump.
