OnePopAllRealms Scenario
The main purpose of the OnePopAllRealms scenario is to illustrate how to configure redundancy. This scenario uses the same centralized and distributed configurations of hosts as the OnePop scenario.
Three realms are configured:
- IP realm
This realm uses essentially the same resolution process as the IP realm for the OnePop scenario. However, some of the constraints differ.
- Shared IP
The resolution process is identical to that for the OnePopShared scenario.
- DN realm
This realm uses essentially the same resolution process as the MultiPop DN realm. However, some of the constraints differ.
This realm also uses the same agents as the MultiPop DN realm. The names of agents and resolvers are essentially the same as those in the MultiPop configuration, although they do not include a POP identifier. By reviewing the scenario, Figure 45 and Figure 46, you can determine exact pictures of the DN realms for the centralized and distributed configurations.
Figure 45 shows the centralized configuration for the scenario. Host DemoHost supports all resolvers and agents. However, because host DemoHost is configured for redundancy, its redundant hosts (DemoHost/One and DemoHost/Two) perform the host function. The redundant hosts are on different machines, and both hosts support the resolvers and agents assigned to the parent host.
The parent host DemoHost also supports two SAE plug-in agents, IpVr and DnVr, which share an event collector. Each SAE plug-in agent has a redundant agent called Demo; these redundant agents also share an event collector. The redundant agents and their shared event collector are assigned to both redundant hosts DemoHost/One and DemoHost/Two.
The redundant agents form a community called nicsaeDemo with the monitor DemoMonitor, which tracks them. The redundant agents are identified in the community by the names DemoHost/One and DemoHost/Two; these names specify their hosts and provide unique identifiers for the redundant agents.
The redundant hosts form a community called DemoHost with the monitor DemoMonitor, which tracks them.

Figure 46 shows the distributed configuration for the scenario. Host OnePopBO supports two resolvers for each realm and a directory agent that is used by different realms. However, because host OnePopBO is configured for redundancy, its redundant hosts (OnePopBO/One and OnePopBO/Two) perform the host function. The redundant hosts are on different machines, and both hosts support the resolvers and agents assigned to the parent host.
Host OnePopH1 supports one resolver for each realm and agents that are used by different realms. Host OnePopH1 is also configured for redundancy, and its redundant hosts (OnePopH1/One and OnePopH1/Two) perform the host function. The redundant hosts are on different machines, and both hosts support the resolvers and agents assigned to the parent host.
However, host OnePopH1 also supports two SAE plug-in agents, IpVr and DnVr, which share an event collector. Each SAE plug-in agent has a redundant agent called onePop; these redundant agents also share an event collector. The redundant agents and their shared event collector are assigned to redundant hosts OnePopH1/One and OnePopH1/Two.
The redundant agents form a community called nicsae with monitor nicSaeMonitor, which tracks them. The redundant agents are identified in the community by the names OnePopH1/One and OnePopH1/Two; these names specify their hosts and provide unique identifiers for the redundant agents.
The redundant hosts OnePopBO/One and OnePopBO/Two are members of a community called OnePopBO. This community supports the monitor, BoClient, which is installed on the machine that supports the NIC proxy. BoClient tracks the connections between the redundant hosts OnePopBO/One and OnePopBO/Two from the point of view of the NIC client (NIC proxy).
Similarly, the redundant hosts OnePopH1/One and OnePopH1/Two are members of a community called OnePopH1. This community has one monitor, H1Monitor, which is located on the same machine as the SAE and tracks the connections among the redundant hosts in the same community, their primary host, and the other hosts in the configuration.
H1Monitor and nicSaeMonitor are part of the monitor process OnePop, which is also installed on the same machine as the SAE. BoClient is part of the monitor process OnePopClient, which is installed on the same machine as the NIC proxy.
