need to control pts/number assignment Linux servers

We just installed 2 LINUX red hat servers with Oracle RAC. When users lofg into each server they are assigned a pts/number. Is there any way to specify a range of pts numbers for each node. So if I log into node one I do not get the same pts number already assigned.

The reason being the two nodes share data and some temp files are dynamically built using the pts number. If each node can have the same pts number assigned the temp files will have conflicts.

We ported from OpenVMS and their cluster software handled this, so it would be could if we could do this from LINUX without having to change programs.

You can't control that. The pts entries don't exist until one is requested, then it is created by the driver.

If temp files are generated using the pts entries then you need to replace the generator. This is a security problem as otherwise anyone could create such a tempfile and gain access to data they shouldn't.

Thanks for info I did change our routines to build temp files by host and pts. This solved our problem.
