I/O Delays by Transaction view (IDLTRIO)


For each transaction processed, the I/O Delays by Transaction view displays the percentage of elapsed time an I/O event contributed to the transaction's response time.

The view identifies any I/O activity delays that occurred for:

  • Database reads and writes
  • PSB reads for programs
  • DMB reads for a database
  • Intent list reads for a program
  • Program fetch
  • Log write-ahead calls

You can access the IDLTRIO view by hyperlinking from the:

  • %I/O Dly field in the IDLTR view of transaction delays
  • Trancode field in the IDLTR view and then selecting the I/O Delays option from the IDLMT Transaction Delay Menu
