When you configure a session with multiple partitions at the target instance, the PowerCenter Server 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
不太明白!
