[INS-30043] The grid infrastructure home does not exist or is empty

I have gotten this error while attempting to re-install Oracle on the UNIX server.

The old version of Oracle was not de-installed properly, and so when new version was being installed, I got an error "[INS-30043] The grid infrastructure home '/u10/app/oracle/product/11.2.0/grid' does not exist or is empty".sion i was installing was and the folder 11.2.0 didn't even exist.

The resolution was quite simple though - manually editing inventory.xml file. It can be found in $ORACLE_BASE/oraInventory/ContentsXML directory. I had to remove the entries pointing to the deleted folders and my issue was resolved.

inventory.xml file lists all the Oracle products installed on the machine and when directories are deleted manually, the entries are not removed from inventory.xml file. That's why it is a good idea to perform a deinstallation when removing any Oracle products from the server as opposed to just manually removing directores (applies to 11.2.0 and higher)
