Searching the Internet, I found this reference to a DD statement (not a parameter) named VIOCTL that is used for a product called VIOPLUS:

Quote:

Check with the Software Group on the use of VIOPLUS, Coding a special DD statement can improve a batch jobs CPU and run time performance. You can reduce the number of EXCP to a VSAM dataset by up to 50% with correct choices, along with reducing run time or response time by 70%. In fact the best performance can be gained by adding the follow statement to any JCL step that uses VSAM.

//VIOCTL DD DISP=SHR,AMP='AMORG',VOL=REF=SYS1.LINKLIB,
// DSNAME=ACTIVATE.NLSR512


I couldn't find anything on XIOCTL.
