Hi Experts,
We are trying to perform patch update for Oracle 11.2.0.2.0 to 11.2.0.4.0 on HP-UX system but getting below error message. can you help us ?

having enough space in /tmp and no environment variables are set for TMP or TMPDIR . it is single instance installation only but having two databases running on same host with different user accounts. we are trying to update one of the database from them.
thanks
Venkata
