TMPDIR variable usage

[benny.lbs]

Would you please let me know when the environment variable $TMPDIR be used ?

I have a job generate so large file with name "APT****" in TMPDIR and final abort.

Per the manual:

TMPDIR. This defaults to /tmp. It is used for miscellaneous internal
temporary data, including FIFO queues and Transformer
temporary storage. As a minor optimization, it can be better to
ensure that it is set to a file system separate to the DataStage
install directory.

Most of the temporary storage locations used by PX are covered by the APT_CONFIG file, this is the exception. I've seen lots of named pipe files created in the directory pointed to by the TMPDIR environment variable but they don't take up a lot of space.

It is likely that TMPDIR and your config file point to the same directory and you need to change the APT_CONFIG locations instead of TMPDIR.

Further, named pipes shouldn't get all that large, since there should be a process draining them as fast as the process that is filling them.

But, if your /tmp file system is small (as is often the case on Solaris systems particularly) you would do well to point TMPDIR to a file system with lots of free space.

After setting the TMPDIR environment variable in each project , should the server be restarted for it to take in effect ?
Because i don't see any files created in the TMPDIR and still it created in /tmp directory only.

It would appear that this may be the case. Try it and let us know.
