Question:  I'm getting the following error when trying to install Oracle12c:

Error in invoking target 'irman ioracle' of makefile '/u01/12c/12c-2/rdbms/lib/ins_rdbms.mk'.

See '/home/oracle/oraInventory/logs/installActions2015-06-02_03-39-30PM.log' for details.

How do fix this Oracle install error?

Answer: You have not followed the pre-install verifications. This "error invoking target irman ioracle of makefile" error comes when required library is missing, disk temp space is low or swap space is low.

If you run into the error "error invoking target irman ioracle of makefile" while trying to install Oracle Database, and the log shows a missing ljavavm12 library, you may need to copy the java library like so:

cp ./u01/app/oracle/product/12.1.0/db_1/javavm/jdk/jdk6/lib/libjavavm12.a ./u01/app/oracle/product/12.1.0/db_1/lib/
