ArcSDE Upgrade direct connect error

[RolandKnietzsch]

I want a database to Oracle 11.2.0.3 and ArcSDE10 SP4 migrate.

ESRI Upgrade Workflow: http://help.arcgis.com/EN/arcgisdesktop/10.0/help/index.html#/Upgrading_an_ArcSDE_geodatabase_in_Ora...

My client PC: Windows XP SP3
                    ArcCatalog 10 SP3
                    Oracle 11g client 32bit

My remote server:  Windows Server 2008 64bit
                             Oracle 11.2.0.3 64bit
                             ArcSDE Schema 9.2


I would like to create a direct connect to perform the upgrade.
sde.oracle11g: db_servicename

The following error is displayed.                 Failed to connect to database. Underlying DBMS error[Unknown errorNo extended error.]

Oracle client works correctly.

Direct connect to other database oracle 11.2.0.1 32bit works fine.

Who can help me?

Service: sde: oracle10g ( you had sde.oracle10g, dont know if that was a typo use : instead of .)
Database:
