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).
