Cannot check metadata db connections and retrieve schemas anymore

[Anonymous]

Good morning,
since this morning, and without apparent reasons, i'm not able to connect to database anymore within TOS (ie. metadata connection checks, sql builder, schema retrieve, schema guess...). This is true for all my workspaces and perhaps is something related to my System, however all my oher apps works properly...
When i run a job that uses tOracleInput or similar, connection goes ok...
here's a stack trace of metadata log i hope it could help
best regards,
gabriele

Hi
There are three possibilities to cause "The Network Adapter could not establish the connection" exception.
1. Wrong ip.
2. Behind a firewall.
3. The listener of Database doesn't start up.
According to your description, I think this may be caused by firewall issue.

Pedro

Hello Pedro,
i checked twice, but proxy settings were definitively correct.
To solve the issue, i had to reinstall TOS. Luckily, i was able to point the fresh install to the old workspace, preserving my settings.
I absolutely have no idea of what wen corrupted
tnx for your support,
gabriele

Hi
I agree with you. Maybe some files of TOS have been corrupted.

Hi PatriceD,
What's the DB type do you want to connect? Is the server running? On which build version you got this issue?
Best regards
Sabrina

Hi,
I have a similar problem for MSSQL Server. Check connection works fine from 'Edit connections'. However, 'Retrieve Schema' fails with the following: This is the same driver that is used in 'Edit connections'
Connection failure, check the database settings or contact your database administrator.

Hi  Dan,
What's the sql server version you are using? 2008 or 2012?
Have you already checked document about:TalendHelpCenterupported systems databases and business applications by Talend components?
