客户机重路由
automatic client reroute is a db2 feature that redirects client applications from the primary database to the standby database immediately after a failover operation is performed.
在执行故障转移(failover)操作之后,automaticclient reroute这个db2特性立即把客户机应用程序从主数据库重定向到备用数据库。
and if automatic client reroute is used in conjunction with hadr, client applications can automatically be rerouted to the dr database copy or site in the event of a failover.
如果结合使用automaticclient reroute和hadr,在发生故障转移时,客户机应用程序可以自动地重新路由到dr数据库拷贝或站点。
you could also mingle automatic client reroute technique with the hadr databases.
您还可以混合使用自动客户端重新路由技术与hadr数据库。
websphere application server doesn「t need to know anything about the standby machine, since the high availability and client reroute features are supported on the db2 server side.
websphereapplicationserver不需要知道有关备用计算机的任何信息,因为在db2服务器端支持高可用性和客户端重新路由功能。
notice that the last command in listing 2 enables the automatic client reroute capability for db2 hadr and port 60000 is the db2 instance port number on the standby machine.
注意,清单2 中的最后命令可以为db2hadr启用自动客户端重新路由功能,并且端口60000是备用计算机上的db2实例端口号。
the essential function of db2 v8.2」s client reroute capability is to move a database connection from one sever to another.
db2v8.2客户机重路由特性的重要功能是将数据库连接从一台服务器转移到另一台服务器。
by default, the db2 automatic client reroute feature retries to establish a connection to the database repeatedly for up to 10 minutes.
在缺省情况下,db2自动客户端重新路由功能每10分钟重新尝试建立到数据库的连接。
when the automatic client reroute feature has been enabled, the db2 reroute logic will check whether or not the standby server can be found.
在启用自动客户端重新路由功能时,db2重新路由逻辑将检查是否可以找到备用服务器。
in addition, db2 hadr is associated with an automatic client reroute (acr) capability to make the failover behavior virtually transparent to its client applications.
另外,db2hadr还与自动客户端路由 (acr)功能相关联,使灾难恢复行为对其客户端应用程序实际上是透明的。
the complimentary technology of automatic client reroute is discussed in a later section.
自动化客户机重路由的互补技术将在后面的一个小节中讨论。
in addition, the automatic client reroute must be updated to point to the primary machine.
另外,必须更新自动客户端重新路由,以指向主要计算机。
step 5: configure databases for automatic client reroute
步骤5:为自动客户机重路由配置数据库
on the primary server (node1), execute the following command from the db2 clp to enable the automatic client reroute feature of hadr
在主服务器(node1)上,从db2clp执行以下命令,从而启用hadr的自动客户机重路由特性
server assisted client reroute for partitioned database environments
用于分区数据库环境的服务器辅助客户机重路由
refer to the db2 documentation on automatic client reroute configuration for the equivalent db2 registry variables and additional details.
请参阅db2文档中有关自动客户端重新路由配置的说明,了解等效的db2注册表变量和其他详细信息。
websphere application server takes the advantage of the technologies provided by db2 udb hadr and the automatic client reroute feature to provide a highly available environment for your applications.
websphereapplicationserver利用了db2udbhadr提供的技术和自动客户端重新路由功能为您的应用程序提供了高可用性环境。
when a db2 hadr takeover occurs, websphere application server re-establishes its connection, leveraging the db2 automated client reroute feature automatically to the standby hadr server.
当db2hadr接管发生时,websphereapplicationserver 将利用db2自动客户端重新路由功能自动重新建立与备用hadr服务器的连接。
