Configuring OID onto the existing IDM domain

Easy enough, when you know how ;)

Start database & listener (of course, your environment is set):

lsnrctl start sqlplus / as sysdba<<EOF startup EOF

Start nodemanager.

/oracle/middleware/wlserver_10.3/server/bin/startNodeManager.sh &

Start the managed servers:

/oracle/middleware/user_projects/domains/OAM_domain/startWebLogic.sh &

Now, start the OID configuration:

/oracle/middleware/Oracle_OID/bin/config.sh

I will be expanding the existing domain

so I need to provide the admin server credentials.

Once that's done, I can choose were to put the
software

Always go for Automatic - see my earlier
article about OID not wanting to run
on privileged ports.
