Very long time for retrieving Oracle Schema with Oracle JDBC driver

[Anonymous]

Hi everybody,
I'm using Talend Studio 4.1 and I have a pb with the retrieving schema function on my oracle connection.
I'm using Oracle 8 and when I want to retrieve the schema it's very very very long.
I see in the workspace log this message :

Any idea?

Hi,
if ORA-00942 error comes in Oracle thaen it means the Table name which you have specified does not exist in database

Tks for your reply, but I don't specify any table name, I try to retrieve the list of all table of my Oracle schema.
I just click on the "retrieve schema" choice on the contextual menu of my metadata dbconnection.
After a very long time, the list of my tables in my schema is present.
If I select one of these tables to retrieve the list of columns, Talend takes 20 minutes to recover (even on a table with 2 columns of 5 records)
Maybe it is my Oracle schema that is rotten

Empty the recycle bin and try retrieving schema...it'll work fine
