Controlling CICS operation

While CICS® is running, you can control its operation by changing CICS system definitions and by deleting and installing resource definitions. Use the CICS Explorer® to control your CICS systems.

About this task

The CICS Explorer operation views provide a view of the CICS resources that support day-to-day operation and management of the enterprise.

If you are running your CICS regions in a CICSplex, you can use CICSPlex® System Manager functions to control the operation of CICS. For information, see Introduction to CICSPlex SM.

CICS supplies a number of transactions that you can use to control CICS and its resources while it is running. It also supplies a variety of utility programs, some of which you can use to help with system management.

Restriction: Some system attributes defined with system initialization parameters cannot be changed while CICS is running; you must restart CICS with changed system initialization parameters.
