Central Inventory is locked by another OUI instance No read permission to Central Inventory Failed in Oracle Opatch Apply 18650065

Hi,

When I apply 18650065 patch to Oracle database 12c, I got ”  Central Inventory is locked by another OUI instance No read permission to Central Inventory ” errors.

I have created Test database from Production database in the new Server. When I apply 18650065 patch to test database i got error like following.

[oracle@MehmetSalih 18650065]$ opatch apply

OPatchSession cannot load inventory for the given Oracle Home /oracle/12.1.0/dbhome_1. Possible causes are:
No read or write permission to ORACLE_HOME/.patch_storage
Central Inventory is locked by another OUI instance

The lock file exists in ORACLE_HOME/.patch_storage
The Oracle Home does not exist in Central Inventory

OPatch failed with error code 73
[oracle@MehmetSalih 18650065]$

This errors are related with incorrect oraInventory parameters.

I have checked oraInventory, parameters are the Old one like following.

[oracle@MehmetSalih ContentsXML]$pwd
/home/oracle/oraInventory/ContentsXML
[oracle@MehmetSalih ContentsXML]$ 
[oracle@MehmetSalih ContentsXML]$ cat inventory.xml
<?xml version="1.0" standalone="yes" ?>

</HOME_LIST>
<COMPOSITEHOME_LIST>
</COMPOSITEHOME_LIST>
</INVENTORY>
[oracle@MehmetSalih ContentsXML]$

I have corrected HOME NAME with new Home like following.

[oracle@MehmetSalih ContentsXML]$ cat inventory.xml
<?xml version="1.0" standalone="yes" ?>
<!-- Copyright (c) 1999, 2011, Oracle. All rights reserved. -->

</HOME_LIST>

Now When I try to apply patch again, it is successfull like following.
