Constraints defined on Java columns of remote tables must be checked on the remote server.
If the constraint checking is attempted on the local server, it fails. Therefore, you must enable trace flag 11220 when you insert, update, or delete data for which constraint checking is done on Java datatypes.
There are two error messages that are specific to Java use with remote data access:
Error 11275 – a statement referencing an extended datatype contained syntax that prevented it from being sent to the remote server. Rewrite the statement or remove the extended datatype reference.
Error 11276 – an object in column '<colname>' could not be deserialized, possibly because the object was truncated. Check that the value of @@textsize is large enough to accommodate the serialized object.
