OCI Networking: implementing Route Table Configuration Leading to Intermittent Connectivity Problems
I keep running into I'm trying to implement I'm having a hard time understanding I'm working on a project and hit a roadblock. This might be a silly question, but I'm working with intermittent connectivity issues with my OCI virtual cloud network (VCN) setup. I have a setup where my application instances are behind a load balancer, and everything seems fine most of the time. However, I occasionally experience timeouts when trying to reach certain services, with errors like `Connection timed out` or `No route to host` appearing in the logs. I have a route table configured as follows: ```json { "cidrBlock": "10.0.0.0/16", "routeRules": [ { "cidrBlock": "0.0.0.0/0", "destination": "Internet Gateway", "networkEntityId": "<IGW_ID>" }, { "cidrBlock": "10.0.1.0/24", "destination": "Subnet", "networkEntityId": "<SUBNET_ID>" } ] } ``` The routing works as expected most of the time, and I have checked the security lists. The inbound rules allow traffic on necessary ports, yet the issues continue intermittently. I’ve tried restarting the load balancer and the instances, but that doesn’t seem to resolve the scenario either. Additionally, I've reviewed the logs but do not see any specific patterns or spikes in traffic that correlate with the timing of the connectivity loss. The instances are running a Java application, and I'm using the OCI Java SDK version 2.12.0. Should I consider increasing the timeout settings or is there a specific best practice for route table configurations that I might be overlooking? Any insights would be greatly appreciated! My development environment is macOS. I recently upgraded to Java 3.11. Is there a better approach? The project is a mobile app built with Java. The stack includes Java and several other technologies. What's the best practice here?
