Help connecting to a postgresql Database

Anonymous — Sat, 16 Nov 2024 11:03:16 GMT

I am brand new to Talend, and watched a youtube video on how to connect to an Amazon Redshift postgresql database using the metadata on Talend. When I press the "check connection" button, it says the connection was successful. When I go to retrieve the schema, it says the connection failed. When I go back to edit my connection, my database "string of connection" is changed. Any idea what's happening? Thanks

Hi jmontgomery,

On which official version did you get that? Is there any error log which is located in <Talend Studio installation path>/workspace/.metadata/.log ?

Best regards
Sabrina

xdishi, I am running version 6.0. Here is the error log I am receiving when trying to retrieve the schema(note, when I initially set up the connection to the database, it says the connection is good, it is only after this does the connection not work anymore):
Connection failure, check the database settings or contact your database administrator.

Hi,
Does this issue repro on your another studio(5.6.x)? Can you connect to your postgresql DB successfully through client without using Talend tool now?
