R12.2 Installation Fails with the error "Database pre-install checks failed"

Issue: 

R12.2 Installation Fails with the error "Database pre-install checks failed"

Cause: 

 I have created R12 Stage directory under root $HOME where as I am performing a single node installation with oracle user. Oracle user could not write to /root directory and the error message is populating continuously. The permissions issue was not reported anywhere in the logs.

Solution:

Moved the Stage directory from /root to /u01 and given ownership to oracle user then the installation moved further.

[root@R12PRODDB ~]# pwd

/root

[root@R12PRODDB ~]# cd R122_Stage

[root@R12PRODDB R122_Stage]# pwd

/root/R122_Stage

[root@R12PRODDB /]# mv /root/R122_Stage/ /u01

[root@R12PRODDB /]# cd /u01

[root@R12PRODDB u01]# ls

app  R122_Stage

[root@R12PRODDB u01]# ls -ltr

total 8

drwxr-xr-x. 3 root   root     4096 Jun  6 10:01 app

drwxrwxrwx. 6 oracle oinstall 4096 Jun 25 17:01 R122_Stage






If this error encounters, check for the permissions on stage area. Oracle & applmgr user should be able to read/write to the stage directory. cd to stage area with oracle & application users.
