Your senior DBA just spent 20 minutes trying to remember which port number connects to the Distribution Service. Again. Your new team member has a bookmark folder with 12 different Oracle GoldenGate URLs. Each with a different port. Half of them don’t work anymore because someone changed the configuration last month. And your security team just sent another email. Another quarterly audit. Another spreadsheet asking you to justify why your GoldenGate Microservices deployment has 15 ports exposed to the network. This is what Oracle GoldenGate 23ai Microservices Architecture gives you: incredible power for real-time data replication. And a port number management nightmare that slowly drives your team insane. I know because I’ve sat in 30 different conference rooms/conversations this year. Same whiteboard diagram. Same conversation. Smart IT leaders pointing at their GoldenGate architecture explaining which microservice runs on which port. And why their DBAs spend more time managing access than managing data. Here’s what nobody tells you when you deploy GoldenGate Microservices: The microservices work great. The port management? That’s the hidden tax you’ll pay every single day. The Port Number Tax: What It’s Really Costing You Let me paint a picture from a $2.8 billion retail operation we worked with recently. Brilliant IT team. Oracle GoldenGate 23ai running perfectly. Real-time replication working like clockwork. But they had this massive three-ring binder. I’m not kidding. A physical binder. Titled “GoldenGate Access Guide.” Inside? Service Manager: Port 9100 Administration Server: Port 9101 Distribution Server: Port 9102 Receiver Server: Port 9103 Performance Metrics Server: Port 9104 And that’s just deployment one. They had four deployments. Each with its own set of ports. Each requiring documentation. Each demanding that DBAs remember or look up which number goes where. Their lead DBA told me something I’ll never forget: “I spend more time explaining port numbers to new team members than I spend teaching them about GoldenGate replication.” Think about that. Oracle built this incredible technology for real-time data integration. And the best talent in the organization is teaching port number memorization. That’s not a training problem. That’s a port number tax. And you’re paying it every single day. What Your Team Actually Needs When I talk to CIOs and VPs of IT about Oracle GoldenGate Microservices deployments, the port number frustration comes up every time: First frustration: “My DBAs waste hours managing port number documentation instead of optimizing our data pipelines.” Your team knows Oracle GoldenGate inside and out. They understand replication topology. They can troubleshoot lag issues in their sleep. They’re experts at what matters. But they’re spending time maintaining wiki pages, updating spreadsheets, and answering Slack messages about which port connects to which service. That’s not why you hired them. Second frustration: “Every security audit turns into a port number interrogation.” Your quarterly security review always includes the same conversation: “Why are ports 9100 through 9115 exposed?” “Why does each microservice need its own port?” “Can’t we consolidate this?” You explain that GoldenGate Microservices Architecture works this way by design. You explain that each service needs its own port. You explain that it’s all necessary. And the security team documents another finding. Another item requiring justification. Another complexity to explain next quarter. Third frustration: “New team members take weeks to learn our access patterns.” Onboarding a new DBA or integrating a contractor should take days, not weeks. But when someone joins your team, they need: A bookmark folder with 15+ URLs Documentation explaining which service lives on which port Training on your specific deployment naming conventions A cheat sheet they’ll refer to for months That’s not onboarding. That’s port number orientation. And it delays the real work by weeks. The Solution: Eliminate Port Numbers From Your Team’s Vocabulary Here’s what changes when you implement NGINX reverse proxy for Oracle GoldenGate: Your entire team accesses everything through one URL. No port numbers. No memorization. No documentation to maintain. Just: https://goldengate.yourcompany.com Service Manager? Same URL. Distribution Server? Same URL. Performance Metrics? Same URL. The reverse proxy handles routing. Your team handles data replication. Your security team sees one exposed port. Not 15. Not 12. Not even 5. One. Port 443. Standard HTTPS. Everything else runs internally, protected behind your reverse proxy. Every security audit gets simpler. Every compliance review gets shorter. Every risk assessment shows improvement. Your onboarding time drops from weeks to hours. New team member? Give them one URL. One set of credentials. Done. They’re productive on day one because they’re not memorizing your port number scheme. Why RHEL 8 Teams Hit a Specific Challenge If you’re running RHEL 8 or Oracle Linux 8, you’ve probably discovered that the default NGINX installation doesn’t meet Oracle GoldenGate 23ai requirements. The default NGINX 1.14 stream won’t work. You need 1.19.4 or higher. And nobody tells you this until you’re troubleshooting connection failures at midnight. We’ve walked 13 teams through this exact scenario. The fix takes mear minutes when you know what to do: # Reset module configuration dnf module reset nginx # Enable the right stream dnf module enable nginx:1.20 # Install NGINX dnf install nginx But discovering you need to do this? That’s cost teams days of troubleshooting. The RheoData Difference: We’ve Done This Before Here’s what we bring to Oracle GoldenGate reverse proxy implementations: We know the gotchas. RHEL 8 module streams. SSL cipher configurations. Certificate chain requirements. The specific settings Oracle’s ReverseProxySettings utility needs. We’ve documented every one through 30+ implementations. We understand your constraints. You can’t take GoldenGate offline during business hours. Your security team needs specific cipher suites. Your monitoring tools need to integrate. Your DBAs need training on the new access patterns. We plan for all of it. We deliver in phases. Quick win in 90 days: Your team gets simplified access and you get your first full night of sleep. Six months: Your security posture improves measurably. Twelve months: You’ve converted infrastructure complexity into a competitive advantage. What Success Looks Like Three months after implementing reverse proxy for that $2.8 billion retailer, here’s what changed: That three-ring binder? Gone. The lead DBA recycled it during an office cleanup. Nobody even noticed it was missing because nobody needed it anymore. Their port number documentation? Deleted. Security audit findings related to exposed services? Disappeared. Time spent onboarding new DBAs? Cut from three weeks to three days. But the real win? Their senior DBA told me: “I finally have time to work on the replication optimization project we’ve been delaying for a year. We’re not managing port numbers anymore. We’re managing data again.” That’s what happens when you eliminate infrastructure friction. Your team remembers why they chose database engineering in the first place. The Investment: Time and Expertise Implementing NGINX reverse proxy for Oracle GoldenGate takes expertise. Not just in NGINX. Not just in GoldenGate. But in how IT operations actually work. You need someone who understands: Why your GoldenGate deployment must stay online during implementation How your security team evaluates cipher configurations What your DBAs need to remain productive during the transition Where your monitoring tools integrate with the new architecture You could spend six months building this expertise internally. Watching videos. Reading documentation. Troubleshooting RHEL 8 module streams at 2 AM. Or you could work with a team that’s done this time and time again and knows exactly how to avoid every pitfall. Your Next Step If you’re tired of infrastructure complexity stealing time from strategic initiatives, let’s talk. Not a sales pitch. A real conversation about your Oracle GoldenGate environment. Your team’s pain points. Your security requirements. Your timeline constraints. We’ll tell you honestly if reverse proxy makes sense for your situation. And if it does, we’ll show you exactly how we’d implement it without disrupting your operations. Schedule a 30-minute GoldenGate infrastructure assessment. No cost. No obligation. Just an experienced perspective on your specific challenges. Because you didn’t become CIO to manage port documentation. You became CIO to drive business value through technology. Let’s make your infrastructure work that way. Why Partner With RheoData?
