Oracle Laptop Network Checks | Generated by AI
Port 1521 is closed on all visible devices on your network. This means we need to check a few things on the Oracle laptop.
Can you please do the following checks on the Oracle laptop and tell me the results?
1️⃣ What is its IP address?
Run this in Command Prompt on the Oracle laptop:
ipconfig
Look for the IPv4 Address under your active network adapter (e.g., 192.168.1.xxx)
2️⃣ Is the Oracle listener running?
Run this in Command Prompt:
lsnrctl status
3️⃣ Is port 1521 open in the firewall?
Run this in Command Prompt (as Administrator):
netsh advfirewall firewall show rule name=all | find "1521"
OR to add the firewall rule if missing:
netsh advfirewall firewall add rule name="Oracle 1521" dir=in action=allow protocol=TCP localport=1521
Once you tell me the IP and the listener status, I’ll guide you through the rest (creating the database user and updating jdbc.properties on your dev machine).
