Oracle connection problem via vpn

Anonymous — Sat, 16 Nov 2024 13:48:49 GMT

When I click Guess Schema on a tOracleInput component I get a The Network Adapter could not establish the connection. The weird thing is I can create a connection with the same exact properties in the DBConnections in the Metadata section. I can also connect with TOAD, EntMan, and Sql Plus. I looked in the log and it has the following error:
java.sql.SQLException: Io exception: The Network Adapter could not establish the connection

I am seeing this exact same issue with Talend Open Studio version 3.2.1 build id r31371-20091020-0242 against:
Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bit Production
With the Partitioning, Real Application Clusters, OLAP, Data Mining
and Real Application Testing options
I can connect to the database outside of Talend from this host, I can create a connection under metadata and it works. I can even use sql builder from the component mode for the component I have created for this connection/schema/table space and the query returns data from the table, but I cannot "Guess schema" in order to get a clean, error free listing of the columns to use in my tMap interface. I don't see in this thread how this user got past the issue. Can someone point me to the answer please? Many thanks!
