Procedure for SVC dump

SVC dumps invoked by the SDUMP macro are usually written as a result of an entry into a functional recovery routine (FRR) or ESTAE routine. The component recovery routine specifies the addresses that are dumped and directs the dump to one of the SYS1.DUMPxx data sets. The SVC dump contains enough information for you to build the keyword string.

You can find the structured search keywords in the Summary Diagnostic Worksheet Figure 1 under the section RETAIN® SEARCH ARGUMENT. Use these keywords in freeform searches.

If the abend code is X'08B', then SMS has experienced a "data in virtual" (DIV) abend. Do the following:

Obtain the registers from the time of abend, using either the IGD300I message or the system diagnostic work area (SDWA).
Examine the contents of register 15. The two low-order bytes contain the DIV reason code related to the abend. Append the reason code to the keyword prefix RC. and record it on the Keyword worksheet.
See the description of the applicable DIV reason code listed under abend code 08B in z/OS MVS System Codes. It might help you define more closely the source of the failure. If it indicates that the problem is external to DFSMSdfp, continue the diagnosis process within the component involved.

If the abend code is X'0F4', then an error occurred during program management binder, DCME, HFS, PDSE, or VSAM RLS processing. Do the following:

Review SYS1.LOGREC for X'0F4' software records, PDSE symptom records, and any other records produced at the time of the error. Program management binder, DCME, HFS, PDSE, and VSAM RLS symptom records are primarily used to identify incidents identified with program management binder, DCME, HFS, PDSE, and VSAM RLS X'0F4' abends. When program management binder, DCME, HFS, PDSE, or VSAM RLS symptom records occur without an X'0F4', use the symptom strings to search for matching problems in the IBM® software support database, and if no errors exist, contact the IBM Support Center.
Prior to the ABEND error, a return code is placed in general register 15, and a unique reason code is placed in general register 0 describing the exceptional condition. Append the reason code from general register 0 to the keyword prefix RSN and record it as a modifier keyword on the Keyword worksheet. Remove the leading zeroes from the return code from general register 15 and append it to the keyword prefix RC. Record it as a modifier keyword on the Keyword worksheet. Using the information from Figure 1 as an example, the modifier keywords would be as follows:
```
abend0f4   rsn21042716  rc24
```
PDSE reason codes are used primarily for searching the IBM software support database; therefore, reason code descriptions are not documented in this information.

To determine keywords for SVC dumps, do the following:

Use IPCS to print the summary dump (SUMDUMP). See z/OS MVS IPCS User's Guide.
The title page of the Summary Diagnostic Worksheet contains the dump header and title page, which provide failure-related symptoms extracted from the dump. (See the example in Figure 1.) One or more of the following symptoms should be present:
- ABENDnnn
- Module or CSECT name or both
- Component Identifier
- Release Level
- Service Level
- FMID
Refer to z/OS V2R2 Problem Management, z/OS MVS Diagnosis: Reference, and z/OS MVS Diagnosis: Tools and Service Aids for a detailed explanation of each symptom.
If you can identify the ABEND CODE by using the dump header and title page, see Building the Abend keyword.
If the dump does not have a header title or does not otherwise enable you to identify the ABEND CODE, use the SUMDUMP printed from the SYS1.DUMPxx data set and continue with Procedure for SYSABEND, SYSMDUMP, or SYSUDUMP.
