I have a 9.2.0.6 DB that was created with AMERICAN US7ASCII character set. When our heavy PC client inserts into a LONG type column and the number of characters is more than 2k we get ORA-03106: fatal two-task communication protocol error If we explicitly set NLS_LANG= AMERICAN_AMERICA.US7ASCII Then the client works fine and we can insert up to 32k characters. We want to do something at the server level (db level) because we can't modify the client because we have 100s of clients that would need to be modified. Any ideas?
