I have two instances in one already has a apex with tomcat and ORDS ,now I want to install another apex in the other instance using the same Tomcat, it's posible?
Yes. You can server two APEX instances installed in different databases, or with Oracle DB 12c installed in two different PDBs using ORDS and Apache Tomcat.
Refer the following thread : One ORDS - Multiple databases
