Solution en https://metalink.oracle.com
Apply the patch for Bug 7039896.
Until this solution was found, the only workaround was to disable Automatic
Shared Memory Management (ASMM) i.e Setting SGA_TARGET=0
Lo appliqué y no jalo


Hice esto y nada:
1. In $ORACLE_HOME/network/admin/listener.ora, of the database where the
Metadata Repository is to be loaded, add the line:
INBOUND_CONNECT_TIMEOUT_LISTENER = 0
2. In the Oracle Server 10g sqlnet.ora, add the line:
SQLNET.INBOUND_CONNECT_TIMEOUT = 0


Hice esto y tampoco:
Solution
As of now only workaround is to disable Automatic Shared Memory Management
(ASMM) i.e Setting
SGA_TARGET=0

EVENT="10235 trace name context forever, level 2"
