One way that I know of for sure is to reinstall the binaries for 8.0.6.. That will rebuild oraInventory, and you can upgrade from there -----Original Message----- From: askdba-bounce@xxxxxxxxxxxxx [mailto:askdba-bounce@xxxxxxxxxxxxx] On Behalf Of Chirag DBA Sent: Tuesday, May 10, 2005 3:31 PM To: askdba@xxxxxxxxxxxxx; Oracle-L Freelists; dba gurus Cc: satyesh.jaiswal@xxxxxxx Subject: [askdba] how to rebuild oraInventory if currupted. Hi Team, One of my DBA friend has 2 machines. On one he was running 8.0.6. To put it on different machine he tar the binaries of the oracle and untar on another machine. DB is working but now he is unable to upgrade. It is asking to do with DISK and it requires lots of configurations. OraInventory was copied over from othere system along with oracle home and installed in different filesystem. =20 Path structure is not same on both machines. Orainventory seems to to get corrupted. Any idea how to rebuild corrupted orainventory?
