Data processing failures
Several problems can cause data processing failures.
- Issues with NULL values in input columns in Parallel Engine Transformer stage
InfoSphere® Information Server 8.5 changed the way that the parallel engine transformer stage handles columns that contain null values. - InfoSphere DataStage jobs have transformer compile errors after you upgrade to version 8.1 or later
InfoSphere DataStage® Version 7.0 jobs that have a transformer stage where a stage variable is set to null do not compile on InfoSphere DataStage Version 8.1. - Converting a nullable source warning message in InfoSphere DataStage
- Problems when you run multiple instances of a job from a job sequence, or from a script that uses dsjob.
A number of related problems can occur when you are running multiple instances of a job from job sequence, or a script that sequences jobs with the dsjob command. - InfoSphere DataStage job monitor fails to initialize
IBM® InfoSphere DataStage job monitor is running but does not generate monitoring information. - Unexpected results in InfoSphere DataStage Parallel Engine Transformer derivations when AsXxx() function results are concatenated with Strings
The parallel engine transformer functions AsInteger(), AsFloat(), and AsDouble() behave differently from other transformer data conversions functions when they are used in derivations where the result is a string. - Unable to open descriptor file to update
An IBM InfoSphere DataStage job fails with the error message Unable to open descriptor file to update: Permission denied.
