Command Reference

Command Reference

DISPLAY Command

DISPLAY Command

Prints summary and detail-level statistics on DB2 ECCR activity to the EDMMSG data set. Also writes DB2 ECCR. summary statistics to the JES job log and MVS hardcopy log.

Syntax

Use the following command syntax:
MODIFY
task_name
,DISPLAY[,SQ|ST]
Alternatively, you can use the following command syntax:
F
task_name
,DI[,SQ|ST]
The
task_name
variable is the DB2 for z/OS ECCR started task name or job name.

Parameter Description

The following parameters are optional:
SQ
Prints the detail-level statistics report in message PWXEDM177085I to the EDMMSG data set. This report shows counts of the SQL inserts, updates, and deletes captured for each table since the ECCR started.
Also prints the summary statistics in message PWXEDM177084I to the JES log and MVS hardcopy log.
If you specify the SQ parameter, do not also specify the ST parameter.
ST
Prints the detail-level statistics report in message PWXEDM177085I to the EDMMSG data set. This report shows the total changes that the ECCR captured since the ECCR started and during the current statistics reporting interval. It also includes the average number of changes that the ECCR captured per second during the current statistics reporting interval.
Also prints the summary statistics in message PWXEDM177084I to the JES log and MVS hardcopy log.
If you specify the ST parameter, do not also specify the SQ parameter.

Example Output

The following summary statistics are written in response to a DISPLAY command to the EDMMSG data set:
PWXEDM177084I KHADB201 capture statistics at 2013-10-23 16.39.13 031 DB2 Log Location 00000000000060D9DD3B.0000.0000 DB2 Log Timestamp 2013-10-23 16.30.01 Current Delay= sec Average Delay= sec DB2 Log records REC_TOT REC_INTV REC_PSEC 5,475 0 0 EDM Messages MSG_TOT MSG_INTV MSG_PSEC 2 0 0
These summary statistics are also written to the JES log and MVS hardcopy log in response to a DISPLAY, SQ or DISPLAY,ST command.
The following summary and detail-level statistics report is written to the EDMMSG data set in response to a DISPLAY,ST command:
PWXEDM177084I KHADB201 capture statistics at 2013-10-24 16.24.30 DB2 Log Location 00000000000061148000.0000.0000 DB2 Log Timestamp 2013-10-24 16.10.52 Current Delay= sec Average Delay= sec DB2 Log records REC_TOT REC_INTV REC_PSEC 7,136 5 0 EDM Messages MSG_TOT MSG_INTV MSG_PSEC 2 0 0 PWXEDM177085I DETAIL LEVEL STATISTICS FOLLOW BELOW MSG_TOT MSG_INTV MSG_PSEC TABLE_NAME 2 0 0 KHALL1.TENCHAR 0 0 0 SYSIBM.SYSTABLESPACE 0 0 0 SYSIBM.SYSTABLES 0 0 0 SYSIBM.SYSCOLUMNS 0 0 0 SYSIBM.SYSFIELDS 0 0 0 SYSIBM.SYSCOPY
In this report, the detail-level statistics in message PWXEDM177085I show totals of changes captured for each table across different time periods.
The following summary and detail-level statistics report is written to the EDMMSG data set in response to a DISPLAY,SQ command:
PWXEDM177084I KHADB201 capture statistics at 2013-10-24 16.24.42 DB2 Log Location 00000000000061148000.0000.0000 DB2 Log Timestamp 2013-10-24 16.10.52 Current Delay= sec Average Delay= sec DB2 Log records REC_TOT REC_INTV REC_PSEC 7,136 0 0 EDM Messages MSG_TOT MSG_INTV MSG_PSEC 2 0 0 PWXEDM177085I DETAIL LEVEL STATISTICS FOLLOW BELOW TABLE: KHALL1.TENCHAR 2 INSERTS, 0 UPDATES, 0 DELETES
In this report, the detail-level statistics in message PWXEDM177085I show counts of inserts, updates, and deletes captured since the ECCR started for each table.
The following table describes all of the fields in the summary and detail-level reports:
Report Field
Description
DB2 Log Location
Displays the RBA of the current location of ECCR processing in the DB2 log.
DB2 Log Timestamp
Displays the time stamp of the last DB2 log record that the ECCR read. This time stamp reflects the date and time that the record was written to the DB2 log.
Current Delay
Displays the delay, in seconds, for the last change record. The delay is the difference between the time when a change record was written to the DB2 log and the time when the ECCR read the record.
Average Delay
Displays the average delay, in seconds, for processing a change record during the statistical reporting period. The delay is the difference between the time when a change record was written to the DB2 log and the time when the ECCR read the record.
REC_TOT
In the DB2 Log records section of the summary report, displays the total number of DB2 log records that were read by the ECCR since the ECCR started.
REC_INTV
In the DB2 Log records section of the summary report, displays the number of DB2 log records that were read by the ECCR since the last statistics reporting interval.
REC_PSEC
In the DB2 Log records section of the summary report, displays the average number of DB2 log records that the ECCR read per second during the current statistics reporting interval.
MSG_TOT
In the EDM Messages section of the summary report, displays the total number of changes that the DB2 ECCR captured since the ECCR started. This count includes backout records.
The PWXEDM177084I message shows a grand total across all tables, whereas the PWXEDM177085I message from a DISPLAY,ST command shows the total for each table.
MSG_INTV
In the EDM Messages section of the summary report, displays the total number of changes that the DB2 ECCR captured since the last statistics reporting interval. This count includes backout records.
The PWXEDM177084I message shows a grand total across all tables, whereas the PWXEDM177085I message from a DISPLAY,ST command shows the total for each table.
MSG_PSEC
In the EDM Messages section of the summary report, displays the average number of changes that the ECCR captured per second during the current statistics reporting interval. This average includes backout records.
The PWXEDM177084I message shows the average across all tables, whereas the PWXEDM177085I message from a DISPLAY,ST command shows the average for each table.
TABLE_NAME
In the EDM Messages section of the summary report, displays the name of the table for which the MSG_TOT, MSG_INTV, and MSG_PSEC statistics are reported.
TABLE
In the detailed SQL operation statistics report, displays the name of the table for which the INSERTS, UPDATES, and DELETES statistics are reported.
INSERTS
In the detailed SQL operation statistics report, displays the total number of inserts on the table since the ECCR started.
UPDATES
In the detailed SQL operation statistics report, displays the total number of updates on the table since the ECCR started.
DELETES
In the detailed SQL operation statistics report, displays the total number of deletes on the table since the ECCR started.
