Problem:

Customers using MFA Drag & Drop to move very large files encounter a Changeman error:

"CMNerror-RC=16 REASON=0020 Reply Buffer Exceeded"

Resolution:

There is a CONFIGPARM that will increase the size of the ChangeMan buffer from 1 Megabyte to the maximum of 3 Megabytes.

CHANGEMAN_XMS_SIZE=3           --- CMN XMS 3 MEGABYTES

Add this to the parmameter dataset pointed to by the  "//XDBIN    DD ..." statement of the MFA started task. Then stop and restart the MFA Started Task.
