While testing our silent Oracle Grid agents installs I ran into error below when (re-)installing into a non-empty Oracle home directory. …

$ ./runInstaller -silent -responseFile /home/oracle/additional_agent.rsp -invPtrLoc /var/opt/oracle/oraInst.loc
.
.
ERROR: Error:"${ORACLE_HOME}/agent11g" subdirectory already exists in Oracle Inventory. Specify another home location.
.
.

This error can easily be overcome by manually editting the ‘inventory.xml file in your ${ORACLE_INVENTOY}/ContentsXML direcotry. …

Find the directory of your Oracle inventory – locatino is defined in the pointerfile oraInst.loc (which on most os-es resides in /var/opt/oracle/oraInst.loc) …

Go to the Oracle inventory root directory and cd to the ‘ContentsXML’ directory, …

Backup your existing inventoy xml file, …

Remove the entry <HOME></HOME> entry in inventory.xml for the Oracle home where you want to re-install. …

Before edit: …

$ cat inventory.xml
<?xml version="1.0" standalone="yes" ?>

</HOME_LIST>
</INVENTORY>

After edit: …

And off you go – reinstalling in your existing Oracle Home is not a problem anymore – because – Oracle deos not know this is an Oracle Home anymore … …

This was carried out on a test system – seems totally harmless to me in this scenario but still use at your own risk. …
