nsds5ReplicaBusyWaitTime. The longer interval gives waiting suppliers a better chance to
gain consumer access before the previous supplier can re-access the consumer.
• If either attribute is specified but not both, nsds5ReplicaSessionPauseTime is set
automatically to 1 second more than nsds5ReplicaBusyWaitTime.
• If both attributes are specified, but nsds5ReplicaSessionPauseTime is less than or
equal to nsds5ReplicaBusyWaitTime, nsds5ReplicaSessionPauseTime is set
automatically to 1 second more than nsds5ReplicaBusyWaitTime.
If Directory Server has to automatically reset the value of nsds5ReplicaSessionPauseTime,
the value is changed internally only. The change is not visible to clients, and it not saved to the
configuration file. From an external viewpoint, the attribute value appears as originally set.
Replica busy errors are not logged by default because they are usually benign. To see the errors,
turn on the replication error logging, log level 8192. The log levels are described in more detail
in the HP-UX Directory Server configuration, command, and file reference.
8.6 Configuring cascading replication
This section provides information on setting up cascading replication. The steps described in
this section provide a high-level overview of the procedure, and cross-references to the detailed
task descriptions are provided at each step.
Setting up cascading replication, as shown in Figure 8-4 “Cascading replication”, has three major
steps, for each server in the scenario, the supplier on Server A, which holds a read-write replica;
the consumer/supplier on hub Server B, which holds a read-only replica; and the consumer on
Server C, which holds a read-only replica:
• “Configuring the read-write replica on the supplier server”
• “Configuring the read-only replica on the consumer server”
• “Configuring the read-only replica on the hub”
• “Setting up the replication agreements”
8.6.1 Configuring the read-write replica on the supplier server
Next, configure the supplier server, which holds the original copy of the database:
1. Specify the supplier settings for the server.
a. In the Directory Server Console, select the Configuration tab.
b. In the navigation tree, select the Replication folder.
c. In the right-hand side of the window, select the Supplier Settings tab.
