INQUIRE SYSDUMPCODE

Description

You can use the INQUIRE SYSDUMPCODE command to look at some of the information in a system dump code table entry.

The table entry tells CICS® what actions to take when a system dump request with this code occurs, and how many times to take them (the MAXIMUM option). Requests received after the maximum is reached are counted (the CURRENT option), but are otherwise ignored.

CICS provides a system dump table with entries for some CICS-defined system dump codes. CICS builds table entries, using default values, when it receives a dump request with a code for which it does not have an entry. You can add your own entries with the SET SYSDUMPCODE command or a CEMT transaction. Entries you add remain over executions of CICS until an initial or cold start occurs, but the entries that CICS builds are considered to be temporary and are discarded at shutdown. Consequently, if you enquire about a code that is not explicitly defined before it appears in a dump request, you get a not found response.

Browsing

You can also browse through all of the entries in the system dump code table by using the browse options (START, NEXT, and END) on INQUIRE SYSDUMPCODE commands. See Browsing resource definitions for general information about browsing, including syntax, exception conditions, and examples.

Options

CURRENT(data-area)

Returns a fullword binary field that shows the number of dump requests with this dump code made since the count was last reset.

The count is reset automatically at CICS shutdown and can be reset explicitly with a SET SYSDUMPCODE command or its CEMT equivalent. The count includes requests that do not result in a dump because either CICS or MVS™ suppressed it.

DAEOPTION(data-area)

Returns a CVDA value that shows whether a dump produced for this dump code is eligible for subsequent suppression by the MVS Dump Analysis and Elimination (DAE) component. CVDA values are as follows:

DAE

The dump is eligible for DAE suppression.

NODAE

The dump is not eligible for DAE suppression. If CICS determines that a dump should be written, MVS does not suppress it.

However, be aware of the SUPPRESS and SUPPRESSALL options in the ADYSETxx parmlib member. These are controlled by the VRADAE and VRANODAE keys in the SDWA, and can lead to dump suppression even though NODAE is set here. For information about DAE, SUPPRESS, and SUPPRESSALL, see z/OS MVS Diagnosis Tools and Service Aids.

DSPLIST(data-area)

Returns a list of data spaces to be dumped. Data space names are separated with commas. This field contains up to 255 characters.

DUMPSCOPE(cvda)

Returns a CVDA value that shows whether a request for a dump with this dump code should cause an SDUMP (system dump) request to be sent to related z/OS® images.

A related z/OS image is one that contains a CICS region doing work on behalf of your CICS region. Specifically, it is a region that has one or more tasks doing work under the same APPC token as a task in your region.

The sending of SDUMP requests occurs only when the table entry for this code specifies a dump (that is, the SYSDUMPING value is SYSDUMP), and only in a sysplex environment executing under MVS/ESA Version 5.1 or later and the z/OS Workload Manager.

CVDA values are as follows:

LOCAL

SDUMP requests are not to be sent.

RELATED

SDUMP requests are to be sent.

Note: A setting of DUMPSCOPE(RELATED) results in a single dump being taken for each affected z/OS image. This dump contains the output from all the affected CICS regions in the image. For more information, see Automatic dump data capture from related CICS regions.

JOBLIST(data-area)

Returns a list of address spaces to be dumped. Address space names are separated with commas. This field contains up to 134 characters.

MAXIMUM(data-area)

Returns a fullword binary field that shows the maximum number of dumps with this code that CICS will take. A value of 999 means the default of no limit.

SHUTOPTION(cvda)

Returns a CVDA value that shows whether the CICS system is to be shut down after a request for a dump with this dump code. CVDA values are as follows:

NOSHUTDOWN

The CICS system is not to be shut down.

SHUTDOWN

The CICS system is to be shut down.

SYSDUMPCODE(data-value)

Specifies the 8-character system dump code about which you are inquiring. A valid code contains no leading or imbedded blanks.

SYSDUMPING(cvda)

Returns a CVDA value that shows whether a dump request with this code should produce a dump or not. Even when a dump is specified, CICS will produce one only when the CURRENT value is no greater than the MAXIMUM, and when system dumps are not suppressed globally (see the DUMPING option of the INQUIRE SYSTEM command. MVS can also suppress the dump if appropriate (the DAE option). CVDA values are as follows:

NOSYSDUMP

A dump is not to be produced.

SYSDUMP

A dump is to be produced.

Note: Dumps from the kernel domain of CICS are not subject to suppression and are taken regardless of SYSDUMPCODE value.
