DISPLAY variable not set: debugging not possible

saraswati · Post by **saraswati** » Sat May 11, 2013 7:48 pm

Hello Friends,

I am trying to debug an operator, in this case - DB2 Stage in my Job because it has aborted with log: Failure executing operator logic.

From the dump, I see the operator number as 52. Hence I have set:
APT_DEBUG_OPERATOR to 52.

However during job run my job aborts with this message for the DB2 Stage:
"DISPLAY variable not set: debugging not possible"

Can any one point out what am I missing here.

Thanks.

Set your DISPLAY environment variable?

The DISPLAY environment variable is used to specfy which display to use. You can find more about it using an internet search.
