I just ran into the same problem as noted here and not sure what stage in my job caused this error. Could you show me how to disable operation combination? Thanks.

Add $APT_DISABLE_COMBINATION to the job and set it to TRUE.

Thank you - Still showing the same messages, not any more that I can pin point to where the error is...

Shouldn't be the same... similar but not the same. Post the messages here.

APT_CombinedOperatorController(0),0: Failure during execution of operator logic. (shown few times)
APT_CombinedOperatorController(0),0: Internal Error: (!exportLog_->hasError()): checksum/checksum.C: 391
Traceback: Could not obtain stack trace; check that 'dbx' and 'sed' are installed and on your PATH
JnPocLocHierSK.LnChecksum_Sort,1: Failure during execution of operator logic.

Then it wasn't added or set correctly, it would seem. Can you double-check that it was added to the job and the value you set it to? Also, one of the first log messages should show all of the environment variables in play when the job runs, is it listed there?

This is very strange that the job ran for a few months and now error out with Chksum again...

$NTZ_DATA_SOURCE = NZSQL [$PROJDEF]
$APT_CONFIG_FILE = /opt/IBM/InformationServer/Server/Configurations/default.apt [$PROJDEF]
$APT_DISABLE_COMBINATION = True

Error:

Checksum,1: Internal Error: (!exportLog_->hasError()): checksum/checksum.C: 391
Traceback: Could not obtain stack trace; check that 'dbx' and 'sed' are installed and on your PATH

Time to get you into your own post... and here we are.

Next question is always going to be - what changed?

I wonder if a NULL value appearing in the column being checksum'ed could cause such an error.

We had a similar issue involving a lookup. Solution was to use a transformer with function NullToZero() on the lookup column.
