VCTRSAVE
- Default
- OFF (Non-CICS®); N/A (CICS)
- Recommended
- OFF (Non-CICS); N/A (CICS)
- Considerations
- The VCTRSAVE option specifies whether any language in the application
uses the vector facility when the user-provided condition handlers
are called.
If you do not have user-written condition handlers registered with CEEHDLR, or your user-written condition handlers do not get vector facility instructions generated by INSPECT statements with ARCH(11), then you should run with VCTRSAVE(OFF) to avoid this overhead.
Performance considerations using VCTRSAVE: On the average, VCTRSAVE(ON) was equivalent to VCTRSAVE(OFF).
