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

Por alguma razão quando o $ORACLE_HOME é removido do inventário, o DBA irá encontrar o erro “Inventory load failed… OPatch cannot load inventory for the given Oracle Home” quando se tentar executar o utilitário do opatch (localizado em $ORACLE_HOME/OPatch/opatch) para verificar os patches aplicados no ambiente de banco de dados Oracle.
Com isso, neste post estarei exemplificando como resolver este problema.

Causa raíz: Por alguma razão o $ORACLE_HOME foi removido do inventário.

Solucao: Simplesmente adicione novamente o ORACLE_HOME ao inventário do banco de dados Oracle.

(Exemplo para 3 ORACLE_HOME de 3 versoes diferentes 11.2.0.3, 11.2.0.4 e 12.1.02:


$ORACLE_HOME/oui/bin/runInstaller -silent -attachHome ORACLE_HOME=/opt/oracle/product/11203 ORACLE_HOME_NAME=dbhome11203  -invPtrLoc /etc/oraInst.loc
$ORACLE_HOME/oui/bin/runInstaller -silent -attachHome ORACLE_HOME=/opt/oracle/product/11204 ORACLE_HOME_NAME=dbhome11204  -invPtrLoc /etc/oraInst.loc
$ORACLE_HOME/oui/bin/runInstaller -silent -attachHome ORACLE_HOME=/opt/oracle/product/12102 ORACLE_HOME_NAME=dbhome12102  -invPtrLoc /etc/oraInst.loc

OPatch succeeded.

For some reason when $ORACLE_HOME was removed from the inventory,the DBA will encounter the “Inventory load failed … OPatch can not load inventory for Oracle Home” error when attempting to run the opatch utility (located in $ ORACLE_HOME / OPatch / opatch) to check the patches applied in the Oracle database environment.
With this, in this post I will explain how to solve this problem.

Solution: Simply re-add the $ORACLE_HOME to the inventory.

(An example of adding 3 ORACLE_HOME):

$ORACLE_HOME/oui/bin/runInstaller -silent -attachHome ORACLE_HOME=/opt/oracle/product/11203 ORACLE_HOME_NAME=dbhome11203  -invPtrLoc /etc/oraInst.loc
$ORACLE_HOME/oui/bin/runInstaller -silent -attachHome ORACLE_HOME=/opt/oracle/product/11204 ORACLE_HOME_NAME=dbhome11204  -invPtrLoc /etc/oraInst.loc
$ORACLE_HOME/oui/bin/runInstaller -silent -attachHome ORACLE_HOME=/opt/oracle/product/12102 ORACLE_HOME_NAME=dbhome12102  -invPtrLoc /etc/oraInst.loc

Root cause: For some reason the $ORACLE_HOME were removed from inventory.

Here an example / DEMO:
