Interpreting the Transaction Analysis report

Using the Log Analysis report produced by the IMS Transaction Analysis utility, you can obtain statistics for individual transactions that are processed in any system.

The Log Analysis report also includes definitions for the format of the detailed report records produced by the IMS Transaction Analysis utility and a list of processing type codes. The absence of times for a message GU call or MPP termination in the report lines indicates an input source or intermediate system report line.

The processing type field is an important one for the interpretation of the detailed report lines. The S code indicates that this line shows a send or receive event for the transaction. You can trace the progress of a cross-system conversation using the codes C, D, P, X, and Y.

The report headings include a column headed ID after the column for the GU to the message queue time. The number shown in a report line under the ID heading matches the sequence in which log input is fed to the Log Merge utility. The field corresponds to starting position 102, the 3-digit field named SYSTEM ID, in the detailed report records.

You can use the sort step to reorder the report records in any order you want, for example, by system ID within transaction code. The default order is the input sequence.
