High Availability and Disaster Recovery deployment options
This section is intended for system administrators responsible for setting up Database Servers for Disaster Recovery or High Availability, or both configurations. Use the following menu options to navigate the SL1 user interface:. This section includes the following topics:. You can configure SL1 to replicate data stored on a Database Server to a Disaster Recovery appliance with the same specifications. You can install the Disaster Recovery appliance at the same site as the primary Database Server although this is not recommended or at a different location.
If the primary Database Server fails for any reason, you must manually perform failover. Failover to the Disaster recovery appliance is not automated by SL1. You can cluster Database Servers in the same location to allow for automatic failover.
A cluster includes an active Database Server and a passive Database Server. The passive Database Server provides redundancy and is dormant unless a failure occurs on the active Database Server. SL1 uses block-level replication to ensure that the data on each Database Server 's primary file system is identical and that each Database Server is ready for failover if necessary.
If the active Database Server fails, the passive Database Server automatically becomes active and performs all required database tasks. The previously passive Database Server remains active until another failure occurs. Each database cluster uses a virtual IP address that is always associated with the primary Database Server. No reconfiguration of Administration Portals is required in the event of failover. There are several differences between these two distinct features:. In all configurations, the primary Database Server or All-In-One Appliance is responsible for processing all inbound email.
To prevent duplicate emails from being processed, all inbound email must be delivered to only the current primary Database Server. When Disaster Recovery is configured, the mail process is configured to be running only on the current primary Database Server. Skip To Main Content. All Files. Submit Search.

Pro SharePoint Disaster Recovery and High Availability
It seems that you're in Germany. We have a dedicated site for Germany. Companies and other organizations depend more than ever on the availability of their Information Technology, and most mission critical business processes are IT-based processes. Business continuity is the ability to do business under any circumstances and is an essential requirement modern companies are facing. High availability and disaster recovery are contributions of the IT to fulfill this requirement.
This chapter describes the MarkLogic features that provide high availability and disaster recovery. The main topics are as follows:. MarkLogic supports online backups and restores, so you can protect and restore your data without bringing the system offline or halting queries or updates. Backups are initiated via administration calls, either via the web console or an XQuery script. You specify a database to backup and a target location.
A DI failure may be typically caused by a hard disk or network failure. In case of software failure, please contact support as soon as possible as the same problem may occur on the DI backup node. To meet these requirements, you can use the Integration cluster pattern deployment. A HA backup node, connected to the main node for data replication, is ready to be switched as main in case the main node fails. The backup node continuously downloads data from the main node in order to be a clone of the main node. However, active features are deactivated computing, data integration,

It seems that you're in Germany. We have a dedicated site for Germany. Few IT professionals take the time to learn what needs to be known to do disaster recovery well.
High Availability HA provides a failover solution in the event a Enterprise Control Room service, server, or database fails. Disaster Recovery DR provides a recovery solution across a geographically separated distance in the event of a disaster that causes an entire data center to fail. We do not provide an internal HA or DR solution. Rather the Automation Anywhere components and configuration leverage your existing HA and DR infrastructure, load balancing, and failover systems to protect your bots and related data.
И развязали против Стратмора непримиримую войну.

Сьюзан и Стратмор в недоумении посмотрели друг на друга. - Что это? - вскрикнула Сьюзан между сигналами. - ТРАНСТЕКСТ перегрелся! - сказал Стратмор. В его голосе слышалось беспокойство. - Быть может, Хейл был прав, говоря, что система резервного питания подает недостаточное количество фреона. - А как же автоматическое отключение.
Времени на сборы ему не дали, да какая разница: ему же обещали, что путешествие будет недолгим - туда и обратно. Двигатели снизили обороты, и самолет с залитого солнцем летного поля въехал в пустой ангар напротив главного терминала. Вскоре появился пилот и открыл люк. Беккер быстро допил остатки клюквенного сока, поставил стакан на мокрую столешницу и надел пиджак. Пилот достал из летного костюма плотный конверт.
