Address space sharing will depend upon system defaults as the environment variable '_BPX_SHAREAS' is not set
The ctgstart script has determined that the environment variable '_BPX_SHAREAS' has not been defined.
The ctgstart script continues.
If the environment variable _BPX_SHAREAS is not set, then whether or not the Gateway daemon runs in a single address space will be subject to the system default. Verify your preferred setting for _BPX_SHAREAS and add the appropriate definition to the environment variable configuration. The recommended setting is _BPX_SHAREAS=YES.
