KD2_X_DB2_SDUMP_SVC_SYS1_DUMP
Confirm shutdown option
- Description
-
SDUMP specifies the type of dump CT/Engine takes whenever an abend occurs.
- Y
- CT/Engine will issue the MVS SDUMP macro to take a dump to the system's dump data sets. This is the default if the CT/Engine jobstep is APF-authorized.
- N
- CT/Engine will not issue SDUMP. This is the default when the jobstep is not authorized.
- S
- CT/Engine will write only a summary dump to the RKLVSNAP DD statement. Please note that IBM Support Services cannot perform problem diagnosis with only a summary dump.
- M
- CT/Engine will request a machine readable dump to the SYSMDUMP DD statement.
Usage Notes:
- 1.
- If SDUMP(N) is specified or defaulted, CT/Engine will take a formatted dump to the RKLVSNAP data set.
- 2.
- If SDUMP(Y) is specified or defaulted, but the SVC dump fails (perhaps the data set is too small), CT/Engine will proceed as if SDUMP(N) was coded.
- 3.
- In all cases a summary listing of the abend is written to RKLVSNAP. The list will contain an abend summary and a dispatcher summary.
- 4.
- If you specify SDUMP(Y), the address space must be APF-authorized; otherwise it will abend. Authorization is not required for the other options.
- 5.
- We recommend that you allow SDUMP to default to the appropriate value.
- 6.
- SYSMDUMP dumps are the same as SVC dumps and must be analyzed using IPCS.
- 7.
- SVC and SYSMDUMP dumps provide several benefits. They complete faster than the formatted dump, reducing the time the address space is non-dispatchable. They cost less to ship than paper dumps. IBM support personnel can perform problem determination faster, using specialized IPCS verb exits and formatting routines.
- 8.
- Only the first dump taken will be written to the SYSMDUMP data set unless the CT/Engine JCL specifies DISP=MOD. In that case subsequent dumps are appended to the end of the data set.
- 9.
- CT/Engine automatically initializes the SYSMDUMP data set with an end-of-file mark during start up. Unless DISP=MOD is specified, any existing dumps in the data set will be overwritten.
- 10.
- If SDUMP(M) is specified, and the SYSMDUMP DD is missing or the data set initialization fails, an error message is issued and CT/Engine terminates.
- 11.
