可用性——测量系统的正常运行时间，并包括高可用性和故障恢复。
Availability a "measures the system 'up-time, and includes high-availability and disaster recovery."
在本文中，我将重点介绍这些可利用来影响SLA中正常运行时间有效性的漏洞。
For this article, I'll highlight those exploitable vulnerabilities that would impact the uptime availability in the SLA.
第一个软目标指定必须保证达到99%(举例而言)或更多的正常运行时间可用性。
The first soft goal specifies uptime availability that must be guaranteed to achieve, say, 99% or more of the time.
使用该脚本，我们可以获取命令行上提供的每个主机的正常运行时间列表(请参见清单6)。
Using the script, we can get a list of the uptimes for each host supplied on the command line (see Listing 6).
如果在过程中过晚回退，会影响正常运行时间，或者让问题复杂化，到了不可能回退的程度。
If the changes get rolled back too late in the process, you could affect uptime or complicate the problem to the point where no back-out is possible.
当正常运行时间可用性将要低于承诺的时间，那么必须要将中断阈值作为性能指标包含进来。
It is important to include the thresholds as a performance indicator when the uptime availability will be less than the guaranteed time.
正常运行时间开始下降会降低到服务水平协议(SLA)上所规定的保证水平之下。
Uptime availability begins to slide down from the guaranteed level set forth in a service level agreement (SLA).
在实现RAID - 1、4和5时，将其视作一种延长正常运行时间的技术是非常重要的。
When you implement RAID-1, 4, or 5, it's very important that you view the technology as something that will enhance uptime.
对于通过SNMP公开其状态的计算机，系统与SNMP代理正常运行时间之间可能存在偏差。
For computers that expose their status through SNMP, there may be a discrepancy between system and SNMP agent uptime.
硬件状态MIB包括有关硬件状态的信息，如温度、日期、固件版本、正常运行时间等等。
The hardware status MIB includes information about the state of the hardware, such as temperatures, date and time, firmware version, uptime, and so on.
如果在一段规定时期之后不再保证正常运行时间有效性，那么将提供信用服务，以下情况除外。
Service of credits will be given if uptime availability is not guaranteed after a specified period of time with the following exceptions.
清单5显示了一个非常简单的脚本，此脚本将获得命令行上提供的每个主机的系统正常运行时间。
Listing 5 shows a very simple script that will obtain the system uptime for each of the hosts supplied on the command line.
通常，HA解决方案的设计由两个因素驱动，正常运行时间(uptime)需求和事务一致性。
In general, HA solution design is driven by two factors, uptime requirements and transactional consistency.
用户必需充分定义所有的安全性策略以确保正常运行时间的可用性保证，而没有或很少有中断阈值。
You must adequately define all security policies to ensure uptime availability guarantees with little or no interruption thresholds.
我考虑了使用SLA来涵盖drm资源，探讨了关于共享资源的正常运行时间可用性的性能测量标准。
I consider covering Shared DRM resources with SLAs. I talk about performance measurement criteria on uptime availability of Shared resources.
策略还应该包含允许企业管理员可以直接与本地管理员通信的特权，以满足正常运行时间的可用性保证。
The policy should also include the privileges that allow the enterprise administrator to directly communicate with the local administrator to meet the uptime availability guarantees.
