In the Active/Active configuration below, both Node1 and Node2 are primary LifeKeeper servers for WebSphere MQ resources. Each server is also the backup server for the other. In this example, Node1 protects the shared storage array for queue manager QMGR1. Node2 protects the shared storage array for queue manager QMGR2 as the primary server. Additionally, each server acts as the backup for the other, which in this example means that Node2 is the backup for the queue manager QMGR1 on Node1, and Node1 is the backup for the queue manager QMGR2 on Node2.
Figure 9 Active/Active Configuration with Shared Storage
Configuration Notes
- The clients connect to the queue manager QMGR1 using the LifeKeeper floating IP 192.168.1.100.
- The clients connect to the queue manager QMGR2 using the LifeKeeper floating IP 192.168.1.101.
- There are heartbeats configured on each network interface.
- Each queue manager has modified the listener object to contain a unique port number.
- QMGR1 data is located on a volume group on the shared storage with two logical volumes configured. Each logical volume contains a file system that is mounted on QMDIR or QMLOGDIR
- QMGR2 data is located on a secondary volume group on the shared storage with two logical volumes configured. Each logical volume contains a file system that is mounted on QMDIR or QMLOGDIR
