Community edition & jdbc

#Development Environment #JDBC #InterSystems IRIS

Hi all,

I'm trying to access via JDBC my community installation but the connection is always rejected. The same code (python code) using the stand-alone version of Intersystems IRIS works fine.

Is the community edition limited in this case? I can't see it in the official documentation: https://irisdocs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page...

Product version: IRIS 2020.3
$ZV: IRIS for UNIX (Ubuntu Server LTS for x86-64 Containers) 2020.3 (Build 221U) Thu Oct 1 2020 11:29:35 EDT

Hi Dmitriy,

Correction: it's not ODBC by JDBC

Actually, when the container is running the error is different than when it's stopped, so I guess my python script really reaches the jdbc server but somehow is not accepted.

Container running:

java.sql.SQLException: java.sql.SQLException: [InterSystems IRIS JDBC] Communication link failure: Communication error:  Server closed communication device

Container stopped:

java.sql.SQLException: java.sql.SQLException: [InterSystems IRIS JDBC] Communication link failure: S’ha refusat la connexió (Connection refused)

Hello David,

Can you double check that you have the port forwarding set up correctly when you start the container? This is the error you will get if you try to connect via JDBC to a port that was forwarded to something other than the instance's SuperServer port. The SuperServer port is 1972. For instance, if you start the container with:

docker run -p 51776:1972 -p 52776:52773 containers.intersystems.com/intersystems/iris-community:2020.3.0.221.0

You should be able to connect using the connection string: "jdbc:IRIS://localhost:51776/USER/". In general, you should be able to connect via JDBC to the community edition containers.
