POSIX(ON) Run-time Option

TIBCO EMS Client for z/OS (CICS) requires that it be able to creates a TCB with POSIX(ON) in the CICS address space.

Because of a z/OS limitation, only one TCB in an address space can have the POSIX(ON) run-time option. If you have other software that also requires this run-time option, that software and TIBCO EMS Client for z/OS (CICS) have to be in separate CICS regions.

For additional information on POSIX, see IBM Language Environment Programming Reference.
