DS_USE_OSHSCRIPT was used when customer's converted from DataStage version 7 to the earlier versions of Information Server version 8 for customer's who may or may not have had GRID (GTK) installed. This is no longer needed with GTK 4.1.5
Diagnosing the problem
If you have GRID (GTK) version 4.1.5 - then the resolution below will resolve the issue. This will also work for customer's who do not have GRID installed.
Resolving the problem
Remove DS_USE_OSHSCRIPT from all DataStage projects and make sure it also doesn't exist in dsenv (located in DSEngine directory). If it is in dsenv, after removing the environment variable, restart DataStage and ASBAgent services.
