12.4.1 Destination Topologies

Figure 12–7 shows the possible destination topology after transforming the Administration Server for Cold Failover Cluster with the following characteristics: ■ The Administration Server Domain Home is moved out onto a shared disk that is mountable by both Node1 and Node2, but is mounted by either one of the two at any given point in time. ■ It continues to use the original Middleware Home available on Node1 and Node2. ■ The Listen Address of the Administration Server is moved to a virtual IP.

12.4.2 Cold Failover Cluster Transformation Procedure

To transform the Administration Server in an existing domain: 1. Shutdown the cluster of the component Managed Servers and Administration Server. 2. Shutdown the Node Manager process on each of the nodes if it is running. 3. Back up of the entire domain. 4. Provision the Virtual IP on Node1. For example: For Linux: ifconfig eth0:1 IP_Address netmask netmask sbinarping -q -U -c 3 -I eth0 IP_Address Where IP_Address is the virtual IP address and the netmask is the associated netmask. In the example below, the IP address is enabled on the interface Local Area Connection. ifconfig eth0:1 130.35.46.17 netmask 255.255.224.0 sbinarping -q -U -c 3 -I eth0 130.35.46.17 For Windows: netsh interface ip add address interface IP_Address netmask Where IP_Address is the virtual IP address and the netmask is the associated netmask. In the example below, the IP address is enabled on the interface Local Area Connection. netsh interface ip add address Local Area connection 130.35.46.17 255.255.224.0 Node 2 Middleware Home Node 1 Shared Storage Admin Server Domain Directory cfcvip.mycompany.com Admin Server Admin Server EM Managed Server CompApp1 Middleware Home Domain Directory CompApp2 Managed Server CompApp1 Domain Directory CompApp2 Admin Server Admin Server EM Active-Passive Topologies for Oracle Fusion Middleware High Availability 12-57 5. Start the Administration Server from the local Domain Home. cd DOMAIN_HOMEbin .startWeblogic.sh 6. Transform the Administration Server instance to Cold Failover Cluster: Log into the Oracle WebLogic Server Administration Console. Create a Machine for the Virtual Host.
