Hi All,

I am facing an fatal error "main_program: Unable to open descriptor file to create: Permission denied" while running a job on Linux Grid.

Job is to create a Lookup FileSet from sequential fileSet.

I have used 2 grid env variable in job, APT_GRID_ENABLE = YES and APT_GRID_COMPUTENODES=1.

Please provide a resolution.

Thanks

There are more grid environment variables you will need to set. The obvious one is APT_GRID_PARTITIONS (companion of APT_GRID_COMPUTENODES). For the Sequential File stage the pathname should be preceded by a reference to APT_GRID_SEQFILE_HOST or APT_GRID_SEQFILE_HOST2 (since sequential file I/O can not be processed on the conductor node unless that is also a compute node, not IBM recommended practice).

You also must provide the Resource Manager Queue name in the $APT_GRID_QUEUE.

Hi Ray,

Thanks a lot for guidance .... I have added Env var APT_GRID_PARTITIONS =1 and APT_GRID_SEQFILE_HOST in Seq. File stage path.

Still the same error persist . Can there be any problem with the permission granted on ID , I am using for creating job.??

Thanks in advance.
