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。
Somewhat obviously, they can be used to check the validity of a block of data such as a journal transaction.
显而易见，这种方式也可以被用来检查写入数据(比如日志事务)的有效性。
If something goes wrong, the catch block rolls back all changes made since the transaction was started, and then prints out an error message.
如果发生了错误，catch块可以回滚事务开始以来发生的所有更改，并打印出一条错误消息。
So if a transaction reached the end of the dosync block, and the STM sees that another transaction has finished since the current one started, then the current one will be rolled back and run again.
Clojure会确保在事务中间该值没有发生改变，因此，如果事务到达了dosync块的结尾，并且，STM可看到在当前事务启动以来有另一事务已经完成了，那么当前事务将回滚并再次运行。
In Listing 6, your multiple API calls inside the batch block guarantee that all the information relative to a purchase order will be updated in a single transaction.
在清单6中，batch块中的多个API调用确保与一个购物订单相关的所有信息将在一个事务中得到更新。
A way to counter the journal corruption is to compute a checksum of the transaction log and write it as part of the commit block process.
对付该问题的一个办法就是，计算一个事务日志的校验和，并把它作为commitblock过程的一部分写到日志中。
Once the entire transaction log has been written to the journal, then a “commit block” is written indicating that the transaction log in the journal is complete.
一旦整个事务内容被写入日志文件中，会写一个“commitblock"到日志文件，以表明日志文件中的事务日志写操作完成。
Furthermore, the behavioral theory of the firm serves as an important building block in transaction costs theory (Williamson, 1975).
此外，企业行为理论还是交易成本理论(Williamson, 1975)的重要基石。
In the current implementation, a new block is generated about every 10 minutes, so it takes at least 10 minutes or so to get a transaction confirmed.
在当前实现中，一个新的数据区块的生成花费大约10分钟，所以至少需要10分钟左右来确认交易。
