Hi experts,
I’m going to describe our current scenario as detailed as possible.
The following dump is being constantly obtained in our ERP 6.0 EHP7 system (Windows 2012/Oracle 11.2.03):
Category Installation Errors
Runtime Errors DBSQL_SQL_ERROR
- Except. CX_SY_OPEN_SQL_DB
Date and Time 12.04.2015 12:47:04
----------------------------------------------------------------------------------------------------
|Short Text |
| SQL error "SQL code: 3113" occurred while accessing table "TSPOPTIONS". |
----------------------------------------------------------------------------------------------------
|What happened? |
| Database error text: "SQL message: ORA-03113: end-of-file on communication |
| channel
Reviewing the developer trace in addition to the above oracle error the ora-03114 and ora-03135 are also present. Please see below>

Even when it’s seems to be a very common issue, almost all notes and SCN questions point me to a solution for distributed system but in my case this is a central one.
The following note describes the scenario exactly as the one we have, but again it seems to apply for distributed systems: 2064591 - work processes reconnect to Oracle database with error ORA-03135. The proposed solution has been tested but with no lack. Also the solution presented in the bellow links but with no result either:
http://www.oracle-experts.info/ora-03135-connection-lost-contact
http://www.inthebasis.com/solve-ora-03135-connection-lost-contact/
Just in case the Windows Firewall has been completely turned off and the NIPING self test is OK.
In addition, the data base library (lib_dbsl_215-10012499.sar) has been updated and we are planning to update the whole kernel and oracle instant client.
Could you please suggest what to check or what would be the recommended troubleshooting?
Thanks
