Error in writing to directory /tmp/OraInstall


firstly, i hope you are not executing runinstaller as root, because it has to be done as oracle. But From what i can make out there’s obviously some issue with your temp directory. So change the /tmp folder. Here’s how to do it.

First, as root:

Code :
mkdir /newtmp

then change owner of newtemp to oracle

Code :
chown oracle:oinstall /newtmp


Code :
chmod 777 /newtmp

then as oracle:

Code :
export TMP=/newtmp
export TEMPDIR=/newtmp

Now try and execute runinstaller and see what happens.
