CICS Transaction Monitor

The ExpeTune CICS Transaction Monitor provides an alternative method to
Watchlists for auto-submitting FreezeFrame requests. Whereas Watchlists cater for
analyses based on historical SMF data, the CICS Transaction Monitor provides
exception-based request triggering.

The monitor consists of a set of CICS programs that are designed to run in a CICS
region where application modules will be driven (a CICS AOR). Their purpose is
to monitor the progress of CICS transactions, and to initiate a FreezeFrame request
if a transaction exceeds its thresholds in terms of allowed execution time, or
allowed CPU time. A log file is created of all FreezeFrame observations requested.
The data is written to the DDNAME EXOLOG in the CICS JCL.

The user dictates the monitor policy by means of a configuration file. This is a
standard text file, prepared using a standard text editor. The file is read when the
monitor starts, and can be refreshed by user request. The file is identified by the
DDNAME EXOCFG in the CICS JCL. If required the configuration file can be
shared between CICS systems.
