ORA-17503: ksfdopn Failed to open file

The ORA-01565 ORA-17503 ORA-01034 ORA-27121 error is related with the Oracle utility permission for both users grid or oracle users in my Case.

To solve this error, I have run the following commands. I have changed executable oracle binary ownership to grid:oinstall and permission to 6751 as follows.

If the problem was related with Oracle database, then you need to do same action for Oracle home instead of Grid Home.

[grid@msdbadm03 grid]$ cd $GRID_HOME/bin/
[grid@msdbadm03 bin]$ 
[grid@msdbadm03 bin]$ ls -ltr oracle 
-rwxr-x--x 1 grid asmadmin 420392488 Sep 9 17:37 oracle
[grid@msdbadm03 bin]$ 
[grid@msdbadm03 bin]$ 
[grid@msdbadm03 bin]$ chown grid:oinstall oracle 
[grid@msdbadm03 bin]$ 
[grid@msdbadm03 bin]$ 
[grid@msdbadm03 bin]$ ls -ltr oracle 
-rwxr-x--x 1 grid oinstall 420392488 Sep 9 17:37 oracle
[grid@msdbadm03 bin]$ 
[grid@msdbadm03 bin]$ 
[grid@msdbadm03 bin]$ chmod 6751 oracle
[grid@msdbadm03 bin]$

 

If you are still getting same error, then go to Oracle database’s Oracle Home and do same action for Oracle database software as follows.

[oracle@msdbadm03 oracle]$ cd $ORACLE_HOME/bin/
[oracle@msdbadm03 bin]$
[oracle@msdbadm03 bin]$ ls -ltr oracle
-rwxr-x--x 1 oracle oinstall 420392488 Sep 9 17:37 oracle
[oracle@msdbadm03 bin]$
[oracle@msdbadm03 bin]$
[oracle@msdbadm03 bin]$ ls -ltr oracle
-rwxr-x--x 1 oracle oinstall 420392488 Sep 9 17:37 oracle
[oracle@msdbadm03 bin]$
[oracle@msdbadm03 bin]$
[oracle@msdbadm03 bin]$ chmod 6751 oracle
[oracle@msdbadm03 bin]$

 

Now you can startup database successfully.
