Hi, I've installed SQL Developer 3.2 build MAIN-09.30 under Windows 7 64 bit and Client 11g 64 bit.
Wherever server I try to connect, when I click on a table I have the connection reset and it tries to fetch data with no success, i.e. the Results display show with the gauge moving and nothing more, while in backgroup I have a message box that suggets to reset the connection. If I stop task and choose some other thing, such as data, I can see tha data inside the table. Getting back to Columns, I have to click on refresh button but I don't see anything.
More, I have the following errors:
SEVERE 51 2348 oracle.dbtools.db.DBUtil Avvertenza. Eccezione non gestita: Errore di I/O: Size Data Unit (SDU) mismatch.
SEVERE 50 22991 oracle.dbtools.db.DBUtil Avvertenza. Eccezione non gestita: Errore di I/O: Size Data Unit (SDU) mismatch.
"Avvertenza. Eccezione non gestita: Errore di I/O" is italian for Warning: Unhandled exception: I/O Error
Can U help me please???
Thanks a lot

The case you describe is not familiar to me, but you may want to review this thread with a similar error: java.sql.SQLRecoverableException Io exception Size Data Unit (SDU) mismatch
The comment there about a "recent JDBC driver upgrade to ojdbc6.jar" is interesting. I encountered a different error within the past couple weeks (can't recall exactly what), but noticed that the ojdbc6 jar files in 64-bit SQL Developer 3.2.09 and Instant Client's do not match. The SQL Developer jar is newer. Copying the one from the Instant Client (126.96.36.199) and replacing the SQL Developer version (supposedly 188.8.131.52 also) fixed whatever issue I faced. Comparing the manifest.mf files shows this:
ojdbc6.jar from SQLDeveloper 3.2.09.23 64-bit -> Repository-Id: JAVAVM_184.108.40.206.0_LINUX.X64_110829
ojdbc6.jar from Instant Client 220.127.116.11 64-bit -> Repository-Id: JAVAVM_18.104.22.168.0_LINUX_120621
This is just my best guess at this point.
Let us know if this helps,
