Disabling constraints in DB2

I am making a JDBC-based application that generates sql scripts to migrate data between databases (even between db vendors). I have one for SQL2000, now I need one for DB2.
The schema has foreign key (FK) constraints, so the mass import needs to shut this off before calling sql insert statements.
In SQL2000, I use this command to disable FK constraints:
ALTER TABLE APPTABLENAME NOCHECK CONSTRAINT ALL;
This does not work in DB2. It does not like the "NOCHECK" part. Anyone know I can fix this?

Don't know for DB2. Probably your best source of info would be the DB2 documentation.
One thing that would be a more generic solution would be to drop the key and add it back upon completion.
I agree. Here's the link:
