CreateOUIProcess(): 13 Permission denied

Error:

Preparing to launch Oracle Universal Installer from /tmp/OraInstall2013-03-19_06-52-06PM. Please wait ...Error in CreateOUIProcess(): 13
: Permission denied







When: While running ./runinstaller

Cause: oracle specific osuser unable to execute temp files from /tmp file system as execute permissions on /tmp was not allowed

$ ls -ld /tmp
drwxrwxrwt. 13 root root 4096 Mar 19 18:48 /tmp
 

Have look at the "." after drwxrwxrwt which means some restriction 



Solution:

1.   Refer below /etc/fstab output for tmp filesystem (rest is truncated from below o/p)



$ cat /etc/fstab
# /etc/fstab
# Accessible filesystems, by reference, are maintained under '/dev/disk'
# See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info
#
/dev/mapper/root_vg-lv_tmp /tmp  ext4  defaults,nodev,nosuid,noexec    1 2
tmpfs              /dev/shm    tmpfs   defaults,nodev,nosuid,noexec        0 0
 



Remove ,nodev,nosuid,noexec  flag , save file . Re-login & run installer
File should look as below (for tmp specific file system only)

$ cat /etc/fstab
# /etc/fstab
# Accessible filesystems, by reference, are maintained under '/dev/disk'
# See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info
#
/dev/mapper/root_vg-lv_tmp /tmp  ext4    defaults    1 2
tmpfs                   /dev/shm    tmpfs   defaults       0 0


Also it is suggested to un-mount & re-mount the /tmp

2.  If solution specified in 1 does not work then set TEMP variable to some valid location having sufficient space & re-try it should work 

$ TEMP=/oradump/11.2.0.1_software/
$ export TEMP

$ ./runInstaller
