OPatch failed to locate Central Inventory.
Possible causes are:
The Central Inventory is corrupted
The oraInst.loc file specified is not valid.
LsInventorySession failed: OPatch failed to locate Central Inventory.
Possible causes are:
The Central Inventory is corrupted
The oraInst.loc file specified is not valid.
OPatch failed with error code 73
The reason for the error is that the content from file /var/opt/oracle/oraInst.loc is different from the content of file $ORACLE_HOME/oraInst.loc (where is supposed it has be the correct info). Usually the problem is that the file is owned by a different user/installation.
Workaround: Check the contents for the correct file $ORACLE_HOME/oraInst.loc and the contents of /var/opt/oracle/oraInst.loc
0. Rename the file: $ mv /var/opt/oracle/oraInst.loc /var/opt/oracle/oraInst.loc.old
1. Copy the new one: $ cp $ORACLE_HOME/oraInst.loc /var/opt/oracle/oraInst.loc
2. Run again the $ opatch lsinventory
$ cd $ORACLE_HOME/OPatch
$ opatch lsinventory
