We installed Talend Open Studio for DI in order to create some tansformation jobs.
As we are accessing production databases with personnal datas, the installation of TOS had been done on Windows 10 VM that have no access to internet (offline network).
We install TOS, we add additional module for JDBC connexion by downloading JDBC jar directly from Oracle, put it on the Talend host. It works fine, we can test the connexion with success.
Now, when we want to change advanced properties on tDbInput or tDbOutput, Talend hangs and we have to close the window. If we try to open other transformation module, it does the same.
I think that Talend try to connect on internet to download some stuff, but it is blocked as the host is not connected, and will not be connected.
Is there something we must configure ? Or how can we download the Talend stuff it searchs, put it on the Talend host and force the local installation ?
On the logs, we can see that sometimes it trys to connect to talend-update.talend.com, and on our Firewall we can see the Talend network dropped from the Talend host.
Hi @DEBOEUF Cédric, I cannot be certain of this but I believe your issue could be that Talend Studio is trying to download Jars required by the components that you are using. For licensing reasons and the size of the download, we do not provide all of the Jars that you will need for all components. Talend will request many of these when you use a component that requires them for the first time. This could very well be your issue.
A way around this when using Talend Open Studio is to build your jobs on a machine that has access to the internet (against a development data source), then export your built jobs to run them on your production system. Once a job is built, this requirement to download missing Jars will no longer be required. It will also allow you to easily use scheduling tools to run the jobs, since they are essentially just Java applications run from the command line.
