Question:

Why would DBID 010 be being opened automatically in one CICS regions but not others?

Answer:

When coding DBCVTPR macro please note that:

- AUTO parameter: List the URTs defined to be opened when required by a program.

- DEFer parameter: List the URTs defined to be opened only by an explicit DBOC/DBEC command (DEF is a valid abbreviation).

- PLT parameter: List URTs opened at CA Datacom CICS Services startup, that is to say those not defined for AUTO or DEFer 

Additional Information:

If one environment open URT 010 (with success or not) then it means that DBURT010 module exists in CICS concatenation loadlib.

Other environments which do not open URT 010 must NOT have that module in CICS concatenation loadlib.
