What is the consistency control?
Consistency check is a strategy used to harmonize data found in the computer system. The idea of checking is to ensure that all data are synchronized between primary and secondary data groups, also known as protective groups and replicas. Consistency control can be configured to take place in the specified times or implemented manually if there is a suspicion of any type of conflict in the data since the last completed check.
The solution of internal conflicts is the main focus of consistency control. Many systems include what is known as Data Protection Manager that checks data in blocks, make sure the protective group and replica are in harmony. If the data update appeared in the Protection Group, but not with a replica, the manager adds an update to the secondary data group and resolves the conflict.
The process of controlling consistency control varies somewhat from one system to another. Usually the sys manager canThe same to create a repeating schedule for checking at least every twenty -four hours. For example, the check can be set to appear every day just before midnight. It is also possible to set recurring checks on specific days of the calendar month or occur on weekly or twice a week. Determination of a schedule of permanent or repeating inspections does not limit the ability of the administrator to perform accidental checks when and as needed.
The actual process of carrying out consistency control may take some time. This is because the control not only looks for exceptions, but actively compares every block of data between the two groups. This allows you to identify any corruption that may have occurred in one or the other group and provides a chance to repair damage. Some systems will indicate discrepancies, allowing the system administrator to check Confridata CTING before it actually gets feltHe knows the chances.
attempt to restart the system while consistency check is usually not recommended. This process can damage data or cause some other bad effect based on how the system is configured. If an emergency consistency check is initiated, it is usually a good idea that end users will stay to use the system for any reason until the check is completed.
In addition to taking time to complete, the consistency control can also slow down other activities in the system. This means that end users may notice changes in how quickly they are able to access different databases or use any of the other programs associated with the system. For this reason, the computer's consistency is often set at the time outside the top, for example, after completing the working day or at night when computer users sleep.
