How to Create a SQLServer2000 failover Cluster How to Create a SQL Server 2000 failover Cluster Before creating an SQL Server 2000 failover cluster, you must Configure Microsoft cluster service (MSC) and use the Cluster Administrator in Microsoft Windows NT4.0 or Windows 2000 to create at least one cluster disk resource. Before running the SQL Server installer,

Load balancing and failover 1, mission objectivesThis task is to solve the server load balancing and failover, this load balancing is to achieve a true sense of load balancing, the actual use, according to the server's various performance indicators for task allocation, in order to achieve fast response, experience high effect. Second, failover is a complement to

OverviewIn the RAC environment to configure Ogg, in order to achieve the RAC node failure, Ogg can automatically failover to the normal node, to ensure that two points:1. ogg's CHECKPOINT,TRAIL,BR file is placed on the shared cluster file system, and the RAC nodes can access the2. Cluster software is required to monitor the Ogg process and automatically restart Ogg (failover) on the normal node in the event
