Options for SDUMP, SYSABEND, SYSUDUMP, and SYSMDUMP

SDUMP options

ALLNUC

All of the DAT-on nucleus, including page-protected areas, and all of the DAT-off nucleus.

ALLPSA or NOALLPSA or NOALL

Prefix storage area for all processors. NOALLPSA or NOALL specifies that these areas are not to be dumped.

COUPLE

XCF related information in the sysplex.

CSA

Entire Common storage area including the high virtual CSA storage and virtual storage for 64-bit addressable memory objects created using one of the following services:

• IARV64 REQUEST=GETCOMMON,DUMP=LIKECSA
• IARCP64 COMMON=YES,DUMP=LIKECSA
• IARST64 COMMON=YES,TYPE=PAGEABLE

GRSQ

Global resource serialization (ENQ/DEQ/RESERVE) queues.

Notes:

1. When the GRS is running in STAR mode, the output of the GRSDATA subcommand is dependent on the GRSQ option setting of the parmlib member GRSCNFxx. For more information about the GRSCNFxx GRSQ setting, see the z/OS MVS Planning: Global Resource Serialization.
2. GRSQ is used for cases where ENQ resources need to be collected. See the "Formatting global resource serialization dump data" section in z/OS MVS Diagnosis: Reference for more information about problems related to GRS itself.

HCSAByASID

High virtual CSA storage that is owned by the ASIDs for which SDUMP captures data. See the ASID parameter for details about the ASIDs that are dumped. The HCSAByASID option was introduced to provide a control that limits the amount of DUMP=LIKECSA dumpable attribute data that is captured; you can elect to capture the data for one subsystem and not another subsystem.

Attention: When this option is specified alone, it might result in the inclusion of none of the above the bar CSA storage in the dump.

This and the other HCSAxxxx options are filters that are introduced as CHNGDUMP options. They assist during installation by controlling the amount of storage that is captured for an SVC dump.

The following table describes how HCSAByASID, HCSANoOwner, and HCSASysOwner affect the CSA storage that is captured in an SVC dump:

Table 1. 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.

HCSANoOwner

High virtual CSA storage for which the owner has ended.

Attention: When this option is specified alone, it might result in the inclusion of none of the above the bar CSA storage in the dump.

HCSASysOwner

High virtual CSA storage that belongs to the SYSTEM.

Attention: When this option is specified alone, it might result in the inclusion of none of the above the bar CSA storage in the dump.

LPA

Link pack area.

LSQA

Local system queue area and virtual storage for 64-bit addressable memory objects created using one of the following services:

• IARV64 REQUEST=GETSTOR,DUMP=LIKELSQA
• IARCP64 COMMON=NO,DUMP=LIKELSQA
• IARST64 COMMON=NO

NUC

Non-page-protected areas of the DAT-on nucleus.

PSA

Prefix storage area of the dumping processor.

RGN

Entire private area and virtual storage for 64-bit addressable memory objects created using one of the following services:

• IARV64 REQUEST=GETSTOR,DUMP=LIKERGN
• IARV64 REQUEST=GETSTOR,SVCDUMPRGN=YES
• IARCP64 COMMON=NO,DUMP=LIKERGN
• IARST64 COMMON=NO

SERVERS

Requests that the registered IEASDUMP.SERVER dynamic exits receive control.

Be warned, however, this setting also causes all synchronous dumps to be converted into asynchronous dumps, which can result in unexpected behavior if the dump requestor was expecting the dump to complete before control was returned to the program. The use of this option is therefore not recommended for general use, so IBM® has defaulted the SERVERS option for all operator initiated and SLIP trap SVC dumps.

SQA or NOSQA

System queue area and virtual storage for 64-bit addressable memory objects created using one of the following services:

• IARV64 REQUEST=GETCOMMON,DUMP=LIKESQA
• IARCP64 COMMON=YES,DUMP=LIKESQA
• IARST64 COMMON=YES,TYPE=FIXED
• IARST64 COMMON=YES,TYPE=DREF

NOSQA specifies that this data not be dumped.

Requests the summary dump function. For a description of NOSUM the summary dump function, see z/OS MVS Programming: Authorized Assembler Services Reference LLA-SDU.

NOSUM or NOSUMDUMP

Requests that the function not be performed.
