Verifying the HA for TimesTen Installation and Configuration

After you install, register, and configure HA for TimesTen, verify this installation and configuration to determine whether the HA for TimesTen data service makes your TimesTen database highly available.

How to Verify the HA for TimesTen Installation for Failover Configurations

1. Assume the root role on a cluster node that is to host the TimesTen component.
2. Ensure that all the TimesTen resources are online.

   For each resource, perform the following steps:

   1. Determine whether the resource is online.

      # clresource status TimesTen-rs

   2. If the resource is not online, bring the resource online.

      # clresource enable TimesTen-rs

3. Switch the resource group to another cluster node, such as node2.

   # clresourcegroup switch -h node2 TimesTen-rg

4. Confirm that the resource is now online on node2.

   # clresource status TimesTen-rs

How to Verify the HA for TimesTen Installation for Scalable or Multiple-Master Configurations

1. Become superuser on a cluster node that is to host the TimesTen component.
2. Ensure that all TimesTen resources are online.

   Perform these steps for each resource.

   1. Determine whether the resource is online.

      # clresource status TimesTen-rs

   2. If the resource is not online, bring the resource online.

      # clresource enable TimesTen-rs

   3. If the resource is online, bring the resource offline, and online again.

      # clresource disable TimesTen-rs
      # clresource enable TimesTen-rs

3. Confirm that the resource is now online on all nodes in the node list.

   # clresource status  TimesTen-rs
