Well ...thanks for you help.

For your information : A software company who sold us an Oracle based application advised us against using MTS because of the strange behaviour. We made our servers (8i on VMS) dedicated. At this moment however we are 'forced' to use Multi Threaded Server because some components under w2k are transactional AND uses databaselinks. (or else ORA 24777: Use of Non-migratable database link not allowed). We did investigate and our DBA is at a loss. Traces don't work en 'killing' some database-processen is the only way (apart from a restart) to make the instances responsive again.

Furher 'investigation' made us find out that a 'pull' mechanisme works fine. So
insert into tableA_at_instanceA select field1, field2, field3 from
tableB_at_instanceB

when we log-on to instanceA (pull) works fine (...uh...we haven't had the Oracle instances hanging YET)

but when we log-on to InstanceB (so we push data to instance A) we still have the hanging problem (to be more exact: 1 row works)
