Preventing Monopolization of the Consumer

NOTE

At the end of this procedure, all supplier servers will have mutual replication agreements, which means that they can accept updates from each other.

NOTE

After creating a replication agreement, the connection type (SSL or non-SSL) cannot be changed because LDAP and LDAPS connections use different ports. To change the connection type, re-create the replication agreement.

5.4.Preventing Monopolization of the Consumer in Multi-Master Replication

One of the features of multi-master replication is that a supplier acquires exclusive access to the consumer for the replicated area. During this time, other suppliers are locked out of direct contact with the consumer. If a supplier attempts to acquire access while locked out, the consumer sends back a busy response, and the supplier sleeps for several seconds before making another attempt. Normally, this is all right; the supplier simply sends its update to another consumer while the first consumer is locked and then send updates when the first consumer is free again.

A problem can arise if the locking supplier is under a heavy update load or has a lot of pending updates in the changelog. If the locking supplier finishes sending updates and then has more pending changes to send, it will immediately attempt to reacquire the consumer and will most likely succeed, since the other suppliers usually will be sleeping. This can cause a single supplier to monopolize a consumer for several hours or longer.

Two attributes address this issue, nsds5ReplicaBusyWaitTime and nsds5ReplicaSessionPauseTime.

•nsds5ReplicaBusyWaitTime. The nsds5ReplicaBusyWaitTime attribute sets the amount of time in seconds a supplier should wait after a consumer sends back a busy response before making another attempt to acquire access. The default is 3 seconds.

•

nsds5ReplicaSessionPauseTime. The nsds5ReplicaSessionPauseTime attribute sets the amount of time in seconds a supplier should wait between update sessions. Set this interval so that it is at least one second longer than the interval specified for nsds5ReplicaBusyWaitTime. Increase the interval as needed until there is an acceptable distribution of consumer access among the suppliers. The default is 0.
