Creating the Central Inventory when it is lost or corrupted

Oracle Universal Installer enables you to set up the Central Inventory on a host or register an existing Oracle home with the Central Inventory, when it is lost or corrupted. You can set up the Central Inventory by using the -attachHome flag of Oracle Universal Installer using the following syntax


./runInstaller -silent -attachHome -invPtrLoc ./oraInst.loc
ORACLE_HOME="Oracle_Home_Location" ORACLE_HOME_NAME="Oracle_Home_Name"
"CLUSTER_NODES={node1,node2,...}" LOCAL_NODE="node_name"

You can use the session variables ORACLE_HOME, ORACLE_HOME_NAME, CLUSTER_NODES, REMOTE_NODES, and LOCAL_NODE.

In a cluster installation, if you don't pass the CLUSTER_NODES session variable, Oracle Universal Installer takes it from the $ORACLE_HOME/inventory/ContentsXML/oraclehomeproperties.xml file.


You may pass the REMOTE_NODES variable if you want to specify the list of remote nodes. If you want to set up the Central Inventory in the local node, you need to pass the -local flag and the REMOTE_NODES variable empty. The syntax is as follows:


./runInstaller -silent -attachHome -invPtrLoc ./oraInst.loc
ORACLE_HOME="Oracle_Home_Location" ORACLE_HOME_NAME="Oracle_Home_Name"
"REMOTE_NODES={}" -local

When you use the -local flag, it performs the action on the local node irrespective of the cluster nodes specified.


For a non-Real Application Clusters setup, you need not pass the LOCAL_NODE variable, and the CLUSTER_NODES variable is empty. The syntax is as follows:

./runInstaller -silent -attachHome -invPtrLoc ./oraInst.loc
ORACLE_HOME="Oracle_Home_Location" ORACLE_HOME_NAME="Oracle_Home_Name"

If the Central Inventory does not already exist, Oracle Universal Installer creates the Central Inventory in the location specified by the oraInst.loc file.
