DB2 SRM BPM Attributes

Use the DB2 SRM BPM attributes to create situations to monitor buffer pool activity.

Allocated Pages The total number of pages allocated to the buffer pool: It includes pages that are currently read or updated, updated pages, and available pages. Valid entry is an integer of up to four digits.

Get Page Rate The number of get page operations per second over last interval. Valid entry is an integer of up to four digits.

Hiperpool Size The size of the hiperpool. Valid entry is an integer of up to four digits.

Interval Time The number of seconds since last sample. Valid entry is an integer of up to four digits.

Origin Node Name The node name of the DB2 system. Valid entry is an alphanumeric text string, with a maximum length of 32 characters.

Pages In Use The number of virtual buffer pool pages in use at the end of the interval (a snapshot value of the current number of non-stealable buffers): A non-stealable buffer is either one which has an outstanding Getpage (someone is currently looking at this page) or one which has been updated and not yet written out to DASD. Valid entry is an integer of up to four digits.

Pool ID The buffer pool ID. Valid entry is an integer of up to four digits.

Prefetch Request Rate The number of prefetch requests issued per second over the last interval. Valid entry is an integer of up to four digits.

Read IO Rate The number of read I/O operations per second over the last interval. Valid entry is an integer of up to four digits.

Time The date and time, as set on the monitored system, indicating the instance when the agent collects information.

The timestamp format for SCAN and STR functions is CYYMMDDHHMMSSmmm (as in 1100315064501000 for 03/15/10 06:45:01) where:
  • C = Century (0 for 20th, 1 for 21st)
  • Y = Year
  • M = Month
  • D = Day
  • H = Hour
  • M = Minute
  • S = Second
  • m = Millisecond

Utilization The percentage of the buffer pool currently in use: It is calculated as: (Pages In Use / Allocated Pages) * 100; the buffer pool may be too small if this is greater than 50%. The range of valid entries is from 0.0 to 100.0.

VP Size The size of the virtual buffer pool. Valid entry is an integer of up to four digits.

Write IO Rate The number of write I/Os performed per second over last interval. Valid entry is an integer of up to four digits.
