After the Tomcat install and deploy, you find the following error messages in the MAT server for the GUI interface.
BPXP014I ENVIRONMENT MUST REMAIN CONTROLLED FOR DAEMON (BPX.DAEMON) PROCESSING.
CSV042I REQUESTED MODULE TUNGRGIF NOT ACCESSED. THE MODULE IS NOT PROGRAM CONTROLLED
CSV028I ABEND306-42 JOBNAME=MATGSRVR STEPNAME=SERVER
According to the description of this error, it means the TUNGRGIF load module is not program controlled. This module is in the main load library of the Mainframe Application Tuner (MAT) product, usually found under HLQ.CEESPLD.
It means the security settings are such that the load library is not program controlled by default. The instructions on how to set that depends on the security product.
For RACF it should be possible using the RALTER PROGRAM command.
