Oracle runInstaller – CreateOUIProcess(): 13 : Permission denied

It is lack of execute permission on filesystem or device when we see Oracle runInstaller die there:
…
Preparing to launch Oracle Universal Installer from /tmp/OraInstall2010-0*-**-**-52-53PM. Please wait …Error in CreateOUIProcess(): 13
: Permission denied

Workaround? easy, $ export TMP=$HOME/tmp, then resume it without any issues.
Let us trace problem now:
$ pwd
/tmp/OraInstall2010-**-**_**-**-**PM/jre/1.4.2/bin

$ ./java
-bash: ./java: Permission denied
Yeah, it is the reason.

$ file java
java: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for GNU/Linux 2.0.0, dynamically linked (uses shared libs), for GNU/Linux 2.0.0, stripped
file is ok, not corrupted.

? interesting. Found good one: http://kb.dbatoolz.com/tp/2817.error_in_createouiprocess_13.html

$ grep -i /tmp /etc/fstab
LABEL=/tmp /tmp ext3 defaults,nosuid,nodev,noexec 1 2
