Moving DataStage from SAN to NAS
Posted: Mon Jun 18, 2007 2:23 pm
This is created an FYI for others who might experience this issue.
The Unix SA was copying the DataStage software and Projects as well as other filesystems from SAN disks to NAS disks. Server jobs ran just fine but Parallel jobs failed with "main program: Fatal error: Duplicate name registration for: splitsubrec, APT_SplitSubRecOperator".
It was finally determined that the filesystems were copied in such a way as to NOT create the symbolic links. Rather all of the files only were copied. After stopping the DataStage daemon again, they recopied the files and all symbolic links. Parallel jobs ran successfully after this was done.
There are many symbolic links in the PXEngine/lib directory. I am sure there are others also.
