- Install FlexDeploy application on two separate Physical Server or Virtual Machines.
- WebLogic
- Install two separate WebLogic Domain to two distinct Managed Servers in single WebLogic domain.
- Deploy FlexDeploy application to both Domains or Managed Servers.
- Tomcat
- Install two separate Tomcat as per Installation instructions.
- Both installation will have configuration for JDBC connection to RAC database.
- WebLogic
- Setup Database cluster for FlexDeploy. This would be RAC cluster for Oracle database. Follow guidelines setup by database vendor for clustering.
- Make sure to use JDBC connect string for database cluster nodes when defining Data Source definitions.
- Use shared file systems for the Artifact Repository directory and the plugins subdirectory of the server Working directory, so that active node and passive node will have access to the files.
- The Artifact Repository location is specified in the flexagon.fd.install.root Java system property of the server.
- The Working Directory location is specified in the flexagon.fd.repository.root Java system property of the server. There is no need to place the entire working directory on a shared file system. The requirement is for the plugins subdirectory only.
- Configure Load Balancer to route all FlexDeploy users to Active Application Server. You can automate the process of fail over to Passive node if necessary.
- Make sure that only one of the Application Server process is running. This is absolutely necessary even when Load Balancer is routing traffic to only one of the server.
- This can be achieved by leaving out some configuration details on the Passive node. For example, you can omit Data Source configuration on Passive node, so that it does not start processing request if it is started by mistake.
