When you configure a session with multiple partitions at the target instance, the Integration Service creates one connection to the target for each partition. If you configure multiple target partitions in a session that loads to a database or ODBC target that does not support multiple concurrent connections to tables, the session fails.
When you create multiple target partitions in a session that loads data to an Informix database, you must create the target table with row-level locking. If you insert data from a session with multiple partitions into an Informix target configured for page-level locking, the session fails and returns the following message:
WRT_8206 Error: The target table has been created with page level locking. The session can only run with multi partitions when the target table is created with row level locking.
Sybase IQ does not allow multiple concurrent connections to tables. If you create multiple target partitions in a session that loads to Sybase IQ, the Integration Service loads all of the data in one partition.
