Hello,
Recently I tried to connect to JDBC on IRIS 2020.3+ and I came across the following error:
SQL Error [461] [08S01]: [InterSystems IRIS JDBC] Communication link failure: Communication error: Server closed communication device
This error implies that the port is not open.
Checking with the netstat command:
irisowner@78c3e30b7f41:/opt/irisapp$ netstat -a
Active Internet connections (servers and established)
