OPatch failed with error code 73

If users copy the ORACLE_HOME from one system to another unix system, make sure you run the clone command. If not the ORACLE_HOME information will not be registered in the oraInventory.

Some times users may get below errors when they copy ORACLE_HOME, ORACLE Inventory from a different system. Note that the path and SID may not be same.

Inventory load failed... OPatch cannot load inventory for the given Oracle Home.

Possible causes are:
   Oracle Home dir. path does not exist in Central Inventory
   Oracle Home is a symbolic link
   Oracle Home inventory is corrupted
LsInventorySession failed: OracleHomeInventory gets null oracleHomeInfo

OPatch failed with error code 73

By running ORACLE_HOME "Clone" command will create new inventory (if missing) and also takes care of re-linking of libraries..etc

$ORACLE_HOME/oui/bin/runInstaller -clone ORACLE_HOME="/home/oracle/product/v11203" ORACLE_HOME_NAME="Ora11203_home1" ORACLE_BASE="/oracle" oracle.sysman.ccr:PRE_REQUISITE=true

Before you run above command make sure you have /etc/oraInst.loc file with inventory_loc and inst_group.
