How to Clone Oracle Inventory if existing Oracle Inventory corrupted

 Cloning Oracle Inventory

perl <ORACLE_HOME>/clone/bin/clone.pl ORACLE_BASE=/sid/oracle/product ORACLE_HOME=/sid/oracle/product/112 ORACLE_HOME_NAME=<home name>

If you get error like 'Oracle home already exist' first detach the home with the below syntax and try clone.pl script.

cd $ORACLE_HOME/oui/bin
./runInstaller -silent -detachHome -invPtrLoc /sid/oracle/product/112/oraInst.loc ORACLE_HOME="/sid/oracle/product/112" ORACLE_HOME_NAME="home name"

You can get the existing home name in inventory.xml (under /sid/oracle/oraInventory/ContentsXML)

Example

-bash-3.2$ ./runInstaller -silent -detachHome -invPtrLoc /sid/oracle/product/112/oraInst.loc ORACLE_HOME="/sid/oracle/product/112" ORACLE_HOME_NAME="home name"
