Starting CICS Transaction Gateway

CICS Transaction Gateway can be started either as a batch job (the recommended option) or from the command line.

When you start the CICS Transaction Gateway, it reads configuration information from ctg.ini, ctgenvvar, and stdenv. When you issue the ctgstart command, you can specify startup options to override this configuration information. These options and their values are described in Options on the ctgstart command.

If XA support is enabled, the recoverable resource management services (RRMS) of the z/OS® sync point manager are required.CICS Transaction Gateway accesses RRMS through CTGRRMS services which run in a separate address space. This address space is started in these circumstances: The CTGRRMS address space remains for the life of the z/OS image. See Enabling CTGRRMS services for information about CTGRRMS services. See Starting, stopping or refreshing the CTGRRMS services for information about how to start, stop and restart CTGRRMS services.

A Gateway daemon cold start option startup is provided. Cold start is for use with XA transactions and ensures residual records in RRS are cleaned up after failure of a transactional component, or by manual intervention by an operator through the RRS panels. For more information see Cold start.
