Start Timing a File or Database Request

Many CICS transactions make file or database requests that are not performed using CICS functions.

The start clock function request does the following:

• Lets the transaction communicate the non-CICS file requests to the MEI
• Records the elapsed time of the request
• Optionally, records the request type

Pair this start clock MEI request with the stop clock request to stop the timing of the request.

Use the following CICS command level program example to code this function:

....+....1....+....2....+....3....+....4....+....5....+....6||7..
