Cause:

Problem in locating the correct Oracle Inventory.

The /etc/oraInst.loc is pointing to a wrong location Cluvfy internally uses the inventory location and if proper inventory location is not found, it will report this error


$ls -la /etc/oraInst.loc

-rwxr-x--- 1 root root 63 Dec 19 2006 oraInst.loc

$ cat /etc/oraInst.loccat

: oraInst.loc: Permission denied


Solution:

Check the /etc/oraInst.loc file and and see if it is pointing to the correct inventory location.

If it is not, correct it to point to the the actual inventory location and then retry the cluvfy operation

#id

uid=0(root) gid=0(root) groups=0(root)

#ls -la /etc/oraInst.loc

-rwxr-x--- 1 root root 63 Dec 19 2006 /etc/oraInst.loc

......It's wrong!

# chmod 644 /etc/oraInst.loc

$ id

uid=500(oracle) gid=500(oinstall) groups=500(oinstall),501(dba)
