1·If you have a read-heavy workload, you might want to set isolation to uncommitted read (UR) at the connection level so that you don't have to specify it in each statement.
如果有一个包含大量读取操作的工作负载，那么您可能想将隔离级别设置为未提交读取(UR)，从而不需要在每个语句中设置隔离级别。
2·The initialization of the split mirror as snapshot performs a crash recovery, rolls back all uncommitted transactions, and makes the database available for any read or write operation.
将分割镜像初始化为快照时，将执行崩溃恢复，回滚所有未提交的事务，并使数据库可以被所有读或写操作访问。
3·When DB2 performs an index or table scan, DB2 will block on a row lock when it comes across an uncommitted row which another transaction has exclusively (X) locked.
DB2 在执行索引或表扫描时，如果遇到一个被另一个事务独占 (X) 锁定的未提交行，那么 DB2 将阻塞在行锁上。
4·Locks prevent uncommitted changes made by one application process from being accessed by other processes.
锁可以防止一个应用程序进程所做的未提交更改被另一个进程访问。
5·If this row lock is protecting an uncommitted UPDATE or DELETE action, DB2 cannot process or ignore the row until the outcome of the change is known.
如果这个行锁在保护一个未提交的UPDATE或DELETE动作，那么DB 2不能处理或忽略该行，直到变化的结果已知。
