ORA-3115 occuring after migration to Oracle 11.1.0.6 on Red Hat

Question

Our application has been running on Tru64 5.1b, Oracle v9 for years quite happily. Since migrating to Red Hat Linux, Oracle 11 we've encountering ORA-3115 errors sporadically from a Pro*C call.
Our C executable maintains a connection to the database. Once the 3115 error occurs it occurs on every query to the database from that executable (other processes continue OK, something with the connection?). Our proram uses Pro*c queries with dynamic binds.
There seems to be no pattern to the frequency with which the error occurs.
The offending bit of code is usually:
EXEC SQL SELECT
UPDATE_INHIBITED,
LAST_UPDATE_TIME,
TO_CHAR(LAST_LIVE_UPDATE, 'HH24:MI:SS DD-MM-YYYY'),
LAST_TRANSACTION,
LAST_TRANSACTION_DG
INTO
:sql_update_inhibited,
:sql_last_update,
:sql_last_operational_update,
:sql_last_trans,
:sql_last_trans_dg
FROM SET_DETAILS
WHERE SET_ID = :sql_set_id;
This code has been unchanged for years. The fact that it usually occurs here probably more because this is the first database call completed as part of a scheduled process.
This problem is having an operational impact (as the updates do not occur) and I really need to get a resoltuion before the Christmas break.
As I said we've just migrated to a new server. There may be configuation parameters that are not perfect. Any suggestions on what we could double check?
Has anyone seen this before? Any ideas how I can work around this?
Thanks,
Beck
