OCA Translation Mode
OCA can process bound, executable object programs generated by B40 and later
versions of the C, COBOL85, FORTRAN, Pascal, and TAL compilers. OCA processes
executable object programs that run only in the Guardian environment. (You cannot
accelerate object programs generated by the COBOL 74 compiler.)
OCA Translation Mode
On TNS/E systems, TNS objects are not run in accelerated mode by default.
You must explicitly accelerate your TNS program as part of the build or install process.
If you explicitly accelerate your program in this way, you are immediately alerted of any
error conditions.
If you have an accelerated object (with the corresponding IPF region) and no longer
want it accelerated, use the Binder CHANGE OCA ENABLE OFF command to disable
acceleration. See CHANGE Command on page 3-15.
Cross-Platform Acceleration
OCA is supported on D-series, G-series, and H-series systems, enabling you to
accelerate TNS object files on the TNS/E platform for execution on the TNS/E platform.
(A file with a TNS region only cannot be executed on the TNS/E platform). The TNS/R
acceleration equivalent, Accelerator, is supported on G-series RVUs, enabling you to
accelerate TNS object files on the TNS/R platform for execution on the TNS/R
platform. Having both accelerators available on both platforms enables you to use
either the TNS/R or TNS/E platform to create files that can be executed with improved
performance on either platform.
