NNMi Dependency on Oracle in High Availability Environments

When Oracle and NNMi both run under High Availability (HA), the NNMi HA resource group must include a shared disk for the NNMi data that is not stored in the Oracle database.

Additionally, consider the following information:

  • If the HA product supports dependencies, the recommended approach is to configure each product to run in a separate HA resource group. The Oracle HA resource group must be fully started before the NNMi HA resource group starts. If both HA resource groups are in the same HA cluster, you can modify the cluster configuration to set resource group ordering. If the HA resource groups are in different HA clusters, make sure that the NNMi HA resource group dependency on the Oracle HA resource group is met.
  • If the HA product does not support dependencies, include the Oracle systems and the NNMi systems in the NNMi HA resource group.
