Can I start a second Naming Service for the same backing store when persistent storage is used?

You can start multiple Naming Services against the same backing store. However, there may be problems when the clients are using things like BindIterators and Clusters. These things have states and may cause confusion during load balancing between the same BindIterator and Cluster on the two different Naming Servers. Since the Naming Servers have not been certified for this particular scenario and its attendant issues not yet addressed, we strongly advised against doing this.

These things have states and may cause confusion during load balancing between the same BindIterator and Cluster on the two different Naming Servers. However, you can go for a Master-Slave configuration with two Naming Servers accessing the same backing store whereby one of them is in a standby mode to provide failover support [NS702].
