Kathey Marsden commented on DERBY-728:
--------------------------------------
Thank you Rick for looking at this.
I too am concerned about the DRDA 255 byte character string limit. I had
thought of it especially in terms of this feature as users may have much longer
paths for database name. I think this general limit extension needs to be
addressed as a different ACR. I think we should open a separate issue for it
and pursue it as a separate ACR with opengroup.
