This section describes how to start CICS® regions.
It assumes that you have already carried out any customization of
CICS, generated any additional support required, and defined all the
necessary CICS system definitions.
About this task
You can start CICS in one of two ways:
Procedure
- Use the MVS™ START command
to start CICS as a started task.
- Submit a CICS batch job to the MVS internal reader.
What to do next
In both methods you determine how CICS starts, and the facilities
and resources that it can use. You do this by specifying values for
system initialization parameters that are used by the CICS startup
procedure. You would normally specify the system initialization parameters
before starting CICS. However, after you have started the initialization
of CICS, you can override the system initialization parameters specified
before startup; for example, to enable a specific facility for that
run of CICS.
