Log manager functions
There are two XPI log manager functions. These are the DFHLGPAX calls:
INQUIRE_PARAMETERS
SET_PARAMETERS
These calls allow you to inquire upon, and set, the log manager parameter,
KEYPOINT_FREQUENCY. The value in this parameter specifies the activity
keypoint frequency of the CICS region.
The INQUIRE_PARAMETERS call
INQUIRE_PARAMETERS returns information about the activity keypoint frequency
of the system.
