Applies to:
Oracle Server - Enterprise Edition - Version: 9.2.0.1 to 11.1.0.99
 
This problem can occur on any platform.
Although this problem was first identified on x86 and x86_64 Linux, it is a generic potential issue when the TMPDIR variable is incorrectly set.
Symptoms

Immediately following my 10.2.0.1 install onto RHEL 4 u3 x86_64 (“default-RPMs”), when the DBCA starts to create the initial DB, the following error pops up:

ORA-12157: TNS:internal network communication error

Changes

First attempted use of the DBCA tool, whether manually, or by "install-requested" automatic instance creation.
Cause

You have the environment variable TMPDIR set to a directory that does not exist.

Solution
Ensure that the TEMP and TMPDIR environment variables are set to a valid file system with at
least 400 MB of writable free space.
