updating listener.ora for extproc in RAC

Hello

Trying to update listener.ora in a 1 node RAC for mgw-extproc requirements and need some input on this please?

In the presence of endpoints_listener.ora, I skipped the host & port values from the listener.ora.

Is the correct way to do it? ...or those should be included?

Below is what I added to listener.ora

--listener.ora ---

LISTENER =

(DESCRIPTION_LIST =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = IPC)(KEY=EXTPROC))

)

)

SID_LIST_LISTENER =

(SID_LIST =

(SID_DESC=

(ORACLE_HOME=/u01/app/oracle/product/12.1.0.2/dbhome_1)

(SID_NAME= mgwextproc)

(ENVS="LD_LIBRARY_PATH=/u01/app/oracle/product/12.1.0.2/dbhome_1/jdk/jre/lib/amd64:/u01/app/oracle/product/12.1.0.2/dbhome_1/jdk/jre/lib/amd64/server:/u01/app/oracle/product/12.1.0.2/dbhome_1/lib")
