Hi,
As I don't want to use the /tmp, I have created a folder /etl/IS/Temp for processing the temp files.
But still I have seen some ade. files created in the temp folder, I have done the below changes but still I have faced this issue.
1) I have changed the /tmp path in the configuration files.
2) Changed the /tmp path in the UVconfig file
3) Disabled the resource tracker.
Please do the need ful.

Check environment variables TMPDIR and, possibly, TEMP.

Did you regenerate the .uvconfig file after changing the uvconfig file?

Yes I regenarated it and changed the TMP_DIR value too but still these files created in the /tmp folder.

Can you tell by the filenames if there's a certiain stage or activity that is creating files in /tmp?

What is the value of UVTEMP in the uvconfig file?
If it's empty, then the engine will use /tmp for some of its temporary files.

I'm not sure what Parallel processes would create ade files. I've seen them in the past generated from the shared memory segments RTI/ISD jobs use and also from Server jobs with IPC stages. Assuming something similar is happening here...

I see ade files under /tmp on version 8.5 that correspond with stage types. For example:
/tmp/ade.DS_project_name.ws_DS_job_name.1316215706774.isd_out
It would appear to be coming from the ISD Output stage. For every web service job (parallel jobs) and every ISD Input and Output stage, I have an ade* file in /tmp.
In this case however, it's a new server. We have not yet gone an changed any settings to move away from /tmp. For example, the uvconfig still has:
UVSPOOL /tmp
UVTEMP /tmp
It seems like I ran into this earlier with Lookup stage errors on a 7.x server where we had pointed everything away from /tmp, but I don't recall for sure, especially whether or not "ade" is in the file name under /tmp.

"ade"is a generic identifier in DataStage. User shared memory segments have a key that begins with "adeb", hashed files have a magic number that begins with "adef", and so on. A different identifier is used when an -itag installation is performed.

I have changed above mentioned path in the UV config and regenarte it but still the files are created.

What are the filenames under /tmp that shouldn't be there?
