I have an old Oracle installation running since 1998. I have an UNIX-HP-UX Workstation with Oracle 8.0.5 Database. The Clients are running on Windows machines. Some processes are running on the Server itself with connection to this Oracle 8.0.5 database. These processes are developed in C with Oracle ProC.
Now i'm changing the HP-UX server to an Win2003-Server with Oracle 11g database. My Windows Client program is now connecting to this Oracle 11g DB. But the Unix processes cannot switch at one time to the new system. For a short time, I want to run these processes on the Unix system, but with connection to the new Oracle 11g database.
But now, i get the error ORA-02248 " invalid option for ALTER SESSION" while starting my unix-process or while starting sqlplus.
Has anyone an idea if (and how) it is possible to connect an Oracle8 client to an Oracle11 database.
Thanks in advance
