The ability to achieve high availability for information systems is not just about technology Technology does not operate in a vacuum The most important factors influencing availability include people, processes, and matching the right availability technology to the current business problem Operational systems are managed by people People implement operational procedures Let s look in more detail at some of the factors that go into creating a highly available environment

typically perform numerous administrative tasks daily, and it only takes one poor choice and a couple of seconds for an administrative or operations error to cause a system failure or to corrupt a database, but it could take hours or even days to recover from that error Human error is unavoidable in even the best of circumstances; however, the resulting downtime usually is avoidable with preparation If you are planning to create a highly available environment for your organization, planning for the ability to recover from human errors must be a priority for your organization You can proactively take steps to minimize downtime and to recover from these errors Human error stems from two main sources: administrative errors and end user errors End user errors can cause any number of data corruption issues such as mistakenly deleting critical data or incorrectly updating a database with the wrong information These types of errors often require the database to be rolled back to a point in time before the corruption Administrative errors can be more serious Administrative errors such as incorrectly changing a database schema or submitting incorrect T-SQL update batches can cause the applications to fail and even require complete database restores Several steps can help reduce both the number of human errors as well as the time required to recover from those errors The first step in reducing the human error factor starts with hiring the best and most qualified personnel for your administrative and operational duties The next step is the establishment of a regular training routine for your administrative personnel to ensure they are up to date with the operational best practices and the technologies in use Additionally, one of the most important steps to curtail potential downtime due to user error is restricting all users access to just the data and services that are required for them to perform their jobs Application developer errors can also have a major impact on application availability For example, coding errors that delete rows from the wrong table or a coding error that results in corrupt data being written to the database can require application updates and even the need to roll back and restore the database To reduce the possibility of such errors, it s important to increase awareness of management about the complexities and responsibilities that are associated with continuous information availability This translates to establishing or maintaining training budgets, as well as ensuring proper development and practices like code walkthrough where peer developers review each other s code changes and adequate quality assurance (QA) processes

The organization should possess written procedures for performing routine operational tasks as well as for performing the steps required to recover from various types of predictable and probable system failures The establishment of standard problemresolution procedures can help operational staff to identify common problem scenarios and give them the ability to more quickly diagnose and resolve a variety of situations These documented operational procedures are usually referred to as run books Lack of documentation leads to haphazard recovery from service outages Inadequate or missing documentation increases the likelihood of omitting required steps or procedures It can also increase the overall time required to troubleshoot a problem or to recover from a system or service failure Additionally, the lack of documentation for routine operational procedures increases the possibility of operator error This is especially true where there is a change in personnel due to either illness or other factors like changes in personnel The establishment of standard change management procedures can also be an important factor in systems availability Change management procedures enable an organization to keep track of the application and database schema changes that occur over the lifetime of an application In addition to providing a standard mechanism for tracking source code and database schema changes, the establishment of change management procedures also enables an organization to roll back to prior know-good configurations in the event that an application or database change results in an error The absence of change management procedures can lead to gross recovery errors, where database schema and application updates can be lost or overridden by subsequent changes that failed to incorporate more recent updates Similarly, the establishment of a standardized QA process will result in higher application quality and fewer code failures Standardized QA processes ensure that code is tested in a safe QA setting before it is deployed in a production environment Two other important processes that have a direct bearing on availability are the creation of standardized hardware and software configurations Whenever possible it s advantageous to create a standardized environment for both the hardware and software configurations your data centers on On the hardware side, uniform hardware components make it easier to effect system repairs and/or replacements in the event of hardware failure In the same way, consistent software configurations make routine operations easier and reduce the possibility of operator error For example, ideally, all servers should be running with the same operating system and service pack level Likewise, all database servers should use the same version of SQL Server with the same service pack level and client data access components Further, systems should utilize standard naming convention and setup practices For instance, all servers should use a standard naming scheme and have standardized drive letters, mapped directories, and share names Likewise, all database servers should use standard database- and object-naming conventions The lack of standard hardware and software configurations
