With Oracle GoldenGate (Microservices) running on Linux, there is a setting that needs to be configured. I you are like me, the internal firewall (firewalld) on many flavors of Linux always sneaks up on you. When installing Oracle GoldenGate (Microservices), you’ll need to open ports on this internal firewall either for standard ports (80 or 443); or you can just turn it off. Seeing that most security professionals would prefer not to turn off the firewall, this means you have to open ports.
To open ports on an internal firewall on Linux, the following should be done:
1. List all allowed ports:
$ sudo firewall-cmd —list-ports
2. Add the port that needs to be opened
$ sudo firewall-cmd —add-port=443/tcp
Note: When using Oracle GoldenGate (Microservices), port 443 or port 80 is only used when running behind an NGINX reverse proxy
3. Make the change permanent
$ sudo firewall-cmd —runtime-to=permanent
After performing these three steps, you should now be able to access the GUI for Oracle GoldenGate (Microservices).

I’m Bobby Curtis and I’m just your normal average guy who has been working in the technology field for awhile (started when I was 18 with the US Army). The goal of this blog has changed a bit over the years. Initially, it was a general blog where I wrote thoughts down. Then it changed to focus on the Oracle Database, Oracle Enterprise Manager, and eventually Oracle GoldenGate.
If you want to follow me on a more timely manner, I can be followed on twitter at @dbasolved or on LinkedIn under “Bobby Curtis MBA”.
