Oracle Intelligent Adapters and Oracle 8.1.7.4.0

We are running into some problems. When we query the oracle database, for resultset more than 128 characters length, the adapter is not able to parse the packets send by oracle database but for queries with resultset less than 128 characters length the query works fine. But the same query when joined with some other database irrespective of resultset less/more than 128 characters does not respond i.e. not able to parse.

If somebody else has experienced this problem please respond.
