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. Run with VCTRSAVE(OFF) to avoid the overhead, except in the following cases:
- You have user-written condition handlers registered with CEEHDLR.
- Your user-written condition handlers get vector facility instructions. This can happen for INSPECT statements at ARCH(11) or above and for zoned and packed computations at ARCH(12) or above.
Performance considerations using VCTRSAVE: On the average, VCTRSAVE(ON) was equivalent to VCTRSAVE(OFF).
