System dump statistics

This section contains the following statistics:

Dump domain: Global statistics - system dump

These statistics fields contain the global data collected by the dump domain for system dumps.

These statistics can be accessed online using the EXEC CICS® COLLECT STATISTICS SYSDUMPCODE command, and are mapped by the DFHSDGDS DSECT. For programming information about the EXEC CICS COLLECT STATISTICS command, see the CICS System Programming Reference manual.

Table 43. Dump domain: Global statistics - system dump
DFHSTUP name Field name Description
Dumps taken SYS_DUMPS_TAKEN is the number of system dumps taken by the whole system during the present run of CICS. This number does not include suppressed dumps. A set of related dumps may be taken across the sysplex if the dump code includes the RELATED option. In this case, the count is incremented by one for the CICS system which initiated the dump. The number is unchanged for all other CICS systems even if they have issued a dump as part of the related request.

Reset characteristic: reset to zero

 

Dumps suppressed SYS_DUMPS_SUPPR is the number of system dumps, requested from the dump domain by CICS or by a user, which were suppressed by one of:
  • A user exit
  • The dump table
  • A global system dump suppression.

Reset characteristic: reset to zero

Dump domain: Resource statistics - system dump

These statistics fields contain the data collected by the dump domain for system dumps, by dump code. They are available online, and are mapped by the DFHSDRDS DSECT.

Table 44. Dump domain: Resource statistics - system dump
DFHSTUP name Field name Description
Dumpcode SDRCODE is the system dump code. This code is a CICS message number with the DFH prefix and the action code suffix (if any) removed. For guidance information about CICS messages, see the CICS Messages and Codes manual.

Reset characteristic: not reset

 

Dumps SDRSTKN is the number of system dumps taken for the dump code identified in the Dumpcode (SDRCODE) field. A set of related dumps may be taken across the sysplex if the dump code includes the RELATED option. In this case, the count is incremented by one for the CICS system which initiated the dump. The number is unchanged for all other CICS systems even if they have issued a dump as part of the related request.

Reset characteristic: reset to zero

 

Dumps suppressed SDRSSUPR is the number of system dumps, for the dump code identified in the Dumpcode (SDRCODE) field, which were suppressed by one of:
  • A user exit
  • The dump table
  • A global system dump suppression.

Reset characteristic: reset to zero

 

NOT IN THE DFHSTUP REPORT SDRTTKN & SDRTSUPR These fields are always zero. They exist here only for compatibility with the transaction dump statistics record format. A transaction dump can force a system dump to be taken as well (it is an option in the transaction dump table), but a system dump cannot force a transaction dump to be taken.

Reset characteristic: not applicable

 

Dump domain: Summary global statistics - system dump

Summary statistics are not available online.

Table 45. Dump domain: Summary system dump global statistics
DFHSTUP name Description
Dumps taken is the total number of system dumps taken by the whole system during the entire run of CICS. This number does not include suppressed dumps. A set of related dumps may be taken across the sysplex if the dump code includes the RELATED option. In this case, the count is incremented by one for the CICS system which initiated the dump. The number is unchanged for all other CICS systems even if they have issued a dump as part of the related request.
Dumps suppressed is the total number of system dumps, requested from the dump domain by CICS or by a user, which were suppressed by one of:
  • A user exit
  • The dump table
  • A global system dump suppression.

Dump domain: Summary resource statistics - system dump

Summary statistics are not available online.

Table 46. Dump domain: Summary resource statistics - system dump
DFHSTUP name Description
Dumpcode is the system dump code. This code is a CICS message number with the DFH prefix and the action code suffix (if any) removed. For guidance information about CICS messages, see the CICS Messages and Codes manual.

 

Dumps is the total number of system dumps taken for the dump code identified in the Dumpcode field. A set of related dumps may be taken across the sysplex if the dump code includes the RELATED option. In this case, the count is incremented by one for the CICS system which initiated the dump. The number is unchanged for all other CICS systems even if they have issued a dump as part of the related request.

 

Dumps suppressed is the total number of system dumps, for the dump code identified in the Dumpcode field, which were suppressed by one of:
  • A user exit
  • The dump table
  • A global system dump suppression.
