OB0956 DATA SET HAS WRONG NUMBER OF COLUMNS - REFORMAT
Explanation
The /ATTACH command generates this message. The cross system data set used for cross system session initialization was formatted for a different screen size (via the COLS= parameter) than that of the director terminal.
System action
OMEGAMON cancels the request.
User response
Reformat the cross system data set with KOBXDSK and specify the proper COLS= value.
