在参与事务中的锁超时事件前执行的所有sql语句信息,如语句文本、使用的隔离级、执行顺序等等。
Information about all SQL statements executed before the lock-timeout event in the participating transactions, such as statement text, isolation level used, order of execution, and so on.
支持表级和行级锁以及4个隔离级别:RR(可重复读)、RS(读可靠)、CS(默认——游标可靠)和UR(未提交读)。
Supports table and row level locking and 4 isolation levels, RR (repeatable read), rs (read stability), CS (default - cursor stability) and ur (uncommitted read).
使用SETISOLATION在会话级、使用with子句在sql语句级或使用数据库配置参数在数据库级设置隔离级别。
ISOLATION level is set at the session level using set ISOLATION, set at the SQL statement level using the WITH clause or set at the database level using a database Configuration parameter.
在接下来的部分,我们不仅会对置于数据库连接上的隔离级有所了解,还将会使用访问意图策略来确定应用服务器是怎样设置这些隔离级的。
The isolation level is set on the database connection and, as we will see later, the access intent policy in use will determine how the application server will set this parameter.
这个隔离级只有当一个事务对同样的数据进行两次读操作而其他事务修改了两次读操作之间的数据,从而导致了每个读操作的结果不同时才会发生。
This happens when a transaction reads the same data twice, while another transaction modifies the data between the two reads, resulting in in a different result for each read.
当其他外部应用程序访问同样的数据库时,了解WebSphereApplicationServer将哪个隔离级置于它和该数据库的连接上是非常重要的。
Knowing what level of isolation WebSphere application Server puts on its connection to the database can be important if there are other external applications accessing the same database.
然而WebSphereApplicationServer中不同的访问意图策略将会为所支持的数据库选择一个合适的隔离级,为开发人员减轻了该细节上的不少麻烦。
However each access intent policy in WebSphere Application Server will choose an appropriate isolation level for supported databases, relieving the developer from this level of detail.
它们提供的环境用于隔离应用程序及其资源,支持应用程序级的检查点、重新启动和重新定位。
Instead, they provide an environment for segregation of applications and their resources to enable checkpoint, restart, and relocation at the application level.
操作系统级的虚拟化是一种服务器虚拟化方法,在这种方法中,操作系统的内核支持多个相互隔离的用户空间实例。
Operating system-level virtualization is a server virtualization method where the kernel of an operating system allows for multiple isolated user-space instances.
这样,被转子磁场隔开的铝罐周围就会产生一个二级磁场,实际上也就能将铝罐与其它废料隔离开来。
This creates a secondary magnetic field around the cans that is repelled by the magnetic field of the rotor, literally ejecting the aluminium cans from the other waste materials.
对应用和服务级安全的支持很广阔,涵盖了从多租户的流程、文件系统和用户级隔离到整个hypervisor一级的隔离。
Application and service level security can range from multi-tenant, with process, file system, and user level isolation, to full hypervisor level isolation.
这种综合流程在不改变原有电路设计的前提下同时采用了门控时钟、操作数隔离和门级功率优化来降低功耗。
This flow could use the gated clock, the operand isolation and the gate level optimization to decrease the power consumption without changing the original design.
本文介绍了模块级可重构计算机HIT -FTC2的冗余管理技术,包括:故障检测,故障屏蔽,故障隔离,系统重构与故障恢复等技术。
The redundancy management technique of modular-level reconfiguration computer system HIT-FTC2 is introduced: fault detection, fault masking, fault isolation, reconfiguration and fault recovery.
在此基础上,通过综合考虑测试与测试、测试与故障隔离结论的关系,提出了系统级故障隔离的间接熵法。
Then, examined the relationship of tests and tests, tests and fault isolation conclusions, an indirect-entropy algorithm for system-level fault isolation strategy is proposed.
系统中采用线性光偶和隔离电源,使前级放大电路和后级电路隔离,保证了系统的安全性。
The EMG preamplifier circuit and other circuits are isolated by high-linearity octocoupier and isolated power that reject the industry interference and improve the security of the system.
