DTRTRAN

The DTRTRAN system initialization parameter specifies the name of the transaction definition that you want CICS to use for dynamic transaction routing.

DTRTRAN={CRTX|name|NO}
This is intended primarily for use in a CICS terminal-owning region, although you can also use it in an application-owning region when you want to daisy-chain transaction routing requests. In a dynamic transaction routing environment, the transaction defined for DTRTRAN must be installed in the CICS terminal-owning regions if you want to eliminate the need for resource definitions for individual transactions.
Note: DTRTRAN does not apply to non-terminal EXEC CICS START requests where the distributed routing program is invoked.
The transaction name is stored in the catalog for recovery during CICS restarts.
CRTX
This is the default dynamic transaction definition. It is the name of the CICS-supplied sample transaction resource definition provided in the CSD group DFHISC.
name
The name of your own dynamic transaction resource definition that you want CICS to use for dynamic transaction routing.
NO
The dynamic transaction routing program is not invoked when a transaction definition cannot be found.
