OEM Grid "Failed to connect to database instance: ORA-03135

Susan YangJan 8 2009 — edited Jan 14 2009

Hello all,

Did anyone know why we get the error in the OEM grid:

Failed to connect to database instance: ORA-03135: connection lost contact (DBD ERROR: OCISessionBegin).

We checked the listener and it is running fine. Can someone advice where to look? Thanks.
