IMS resource utilization files (IRUFs)

The BMC AMI Ops Monitor for IMS Offline product components get their input from IMS resource utilization files (IRUFs). IRUFs are sequential data sets in variable blocked spanned (VBS) format. They can be detailed, summarized, or extracted files. The Performance Reporter and the Transaction Accountant generate their performance and accounting reports using IRUFs as input.

Key concepts

IRUFs and the BMC AMI Ops Monitor for IMS Offline product transaction accounting system are based on the BMC AMI Ops Monitor for IMS Offline customer ID field. This field associates all resource usage measurements and costs with a specific user. The default value for the customer ID field is the LTERM name. Both the IRUF transaction accounting record (TAR) and the IRUF terminal (LTERM) accounting record (LAR) maintain a record of the customer ID.

BMC AMI Ops Monitor for IMS Offline uses customer ID information for summarization and charge-out billing. The Transaction Accountant program uses the customer ID information to associate resource usage charges with specific customers. All charges are calculated at the transaction level and are accumulated for each customer category.

You can gain access to each record processed from the IMS log and to all the IRUF data records through exit routines in the Log Edit process (see Log-Edit).
