DataStage® Release: 11x
Job Type: Parallel
OS: Unix
Additional info: Sequential File
Hi,

I have a job that reads from a sequential file, and then links to a transformer and does several other things after that.

This job was written by someone else, and I am trying to tune it.

The job reads from a fixed width file - about 130 GB in size. I am trying to see if I can improve performance by either increasing the "number of readers" or "read from multiple nodes"

However, this, as well as several other options like "Filter" are not visible in this stage.

If I plop a brand new instance of the sequential file stage, and add a output link, I see all the options.

If I use the link to the transformer as the output link, the options are not visible anymore.

Any insights into why these options disappear will be greatly appreciated.

Gaelyn

Never mind -- I answered my own question Smile .. it's because I was reading from file pattern and not a single file.

I need to change the job, because we are reading a single file, not multiple
