The tips below are applicable for ORDS 18.x standalone, for example after a deployment on an OCI dbsystem.
#1 To configure the access.log, update the file standalone.properties available from the /u01/app/oracle/product/ords/config/ords/standalone/standalone.properties configuration file to add the following property
Where /tmp/ords is going to be a directory that will hold the daily logfiles. Then restart the ords standalone process.
standalone.access.log=/tmp/ords
#2 To implement some redirect for the internal ords port to be accessible from the standard https port 443, instead of the native port 8443, create the file https (for example) in /etc/xinetd.d, with the following content:
service jetty-https { disable = no type = UNLISTED socket_type = stream protocol = tcp wait = no redirect = localhost 8443 port = 443 user = nobody }
Then restart the xinetd.d service
service xinetd restart
Check that the firewall and the ingress rules allow inbound access to 443.
