Hi,

I used copy with IEBGENER but I got the following messages in spool. Why is SYNCSORT is being invoked?

SYNCSORT COPY FEATURE CALLED - RC = 0

Is it a normal behavior? What if I need to invoke only IEBGENER specifically? Can that be done?

because when Your support installed SYNCSORT decided ( when possible )
to force the use of SYNCSORT rather than that of IEBGENER ( Better performance )

In most of the shops, IEBGENER now defaults to using the SORT product unless the control statements override the use of the SORT product. As in your example, you've invoked IEBGENER for a straight copy (SYSIN DD DUMMY) and that has invoked the SORT product to do the copy instead.

As per SyncSort, if you are running SyncSort for z/OS and the BetterGener function has been enabled (installed) - in straight copy tasks, as per SyncSort, it offers improved performance over IEBGENER and under the covers SyncSort is invoked. Once BetterGener is activated, eligible IEBGENER job streams are automatically processed by SyncSort and that's why, as Enrico has said, you see that behavior.
