Websphere 7集群部署
我们有一个 J2EE 应用程序作为 EAR 文件,部署在 WAS 7 中,为了使应用程序可用性尽可能高,需要部署在 3 个集群中。我们有一个 Quartz Scheduler 类,其工作是每天凌晨 2:00 将数据从一个数据库上传到另一个数据库。
现在的问题是,如果将ear部署在3个不同的节点上以实现负载均衡和高可用性,则所有3个ear文件将同时触发上传。我们该如何处理这个问题。是否可以在WAS 7环境中进行一些配置。任何帮助/建议将不胜感激。
谢谢
We have a J2EE application as EAR file which is deployed in WAS 7, for making the application availability as high it needs to be deployed in 3 clusters. We have a Quartz Scheduler class whose job is to upload data from one database to another daily at 2:00 am.
Now, the problem is if the ear will be deployed in 3 different nodes for load balancing and high availability, all the 3 ear file will trigger the upload at the same time. How we can handle this. Is it possible to do some configuration in WAS 7 environment. Any help/suggestion would be appreciated.
Thanks
