  • a report interval, move the cursor to the line you want, enter one of the following selection letters, and press Enter.
    A
    Thread history by Plan. For more information, see the description of panel Thread History By Plan.
    B
    Thread history by Authid. For more information, see the description of panel Thread History By Authid.
    C
    Thread history by Plan, Authid. For more information, see the description of panel Thread History By Plan, Authid.

Fields

Report Interval
The time interval by which the report period is partitioned. For more information, see the description of panel Near-Term Thread History Filter Options.
Start
The start date and time of the first interval in the display.
Report Filtered
This field shows YES if thread filter values were used to create this display. Otherwise, NO is displayed.
End
The end date and time of the last interval in the display.
Time
The time of the start of the report interval.
Thrds
The number of threads completed in this interval.
Commit
The number of successful commits performed in this interval. For attachments that use two-phase-commit protocol, this count represents the number of phase two commits. For others, this count represents the number of single-phase commit (sync) requests.
Abort
The number of successful rollbacks performed in this interval.
DML
The number of DML calls issued in this interval.
DLk/TOut
The number deadlocks and timeouts occurred in this interval.
In-DB2 Elap Tm
The elapsed time spent in Db2 for this interval. Accounting class 2 data is required. Displays N/A if accounting class 2 data is not available.
In-DB2 CPU Tm
The CPU time spent in Db2 for this interval. Accounting class 2 data is required. Displays N/A if accounting class 2 data is not available.
In-DB2 Wait Tm
The time spent waiting in Db2 for this interval. Accounting class 3 data is required. Displays N/A if accounting class 3 data is not available. Db2 Accounting class 3 wait events are:
  • Synchronous I/O waits
  • Asynchronous Read I/O waits
  • Asynchronous Write I/O waits
  • Lock/latch waits
  • Page latch waits
  • Drain lock waits
  • Drain of claims waits
  • Db2 service task waits
  • Archive Log Mode(QUIESCE) waits
  • Archive read from tape waits
Getpage
The number of Getpage requests issued in this interval.
GetP/RIO
The ratio of Getpage requests to synchronous Read I/Os for this interval.
