这是因为export工具被绑定为具有游标稳定性(CS)隔离级别(有关DB 2隔离级别的描述，请参阅侧栏)。

That is because the export utility is bound with the cursor stability (CS) isolation level (for a description of the DB2 isolation levels, see the sidebar).

我一直认为read_committed (DB 2调用游标稳定性(CS))意味着你不锁上读，那你只能读提交的数据。

I've always thought that READ_COMMITTED (DB2 calls it Cursor Stability (CS)) meant that you do NOT lock on reads, and that you only read the committed data.

释放行锁，以便其他应用程序可以对表执行SELECT、INSERT、UPDATE和DELETE(例如，使用游标稳定性(curs or stability)隔离级别或未提交读(uncommitted read)隔离级别)。

Release the row locks so that other applications can SELECT, INSERT, UPDATE, and DELETE from the table (for example, use isolation level cursor stability or uncommitted read).
