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 18 (page 324), 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” (page 348)
• “Configuring the read-only replica on the consumer server” (page 350)
• “Configuring the read-only replica on the hub” (page 351)
• “Setting up the replication agreements” (page 355)
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.
