We have the follow scenario :
Two Oracle servers running on two different machines connected by a LAN (TCP/IP). One of them (GSEE8i) is running the Oracle8i Enterprise Edition Release 8.1.7.0.0 version and the other (GSEE9i) is running the Oracle9i Enterprise Edition Release 9.2.0.1.0 . I've created a database link on the GSEE8i to connect to the GSEE9i, and it works fine using SQL*Plus or even with the ODAC components at design time.
At runtime the applications are rising an "ORA-03113: end-of-file on communication channel" error

Can anybody help me please on this matter ?
