TROUBLESHOOTING

Tools for troubleshooting replication
Database access control list problems, server crashes, protocol problems, and incorrectly configured Connection documents are common causes of replication errors. Use these tools to troubleshoot replication.

Cluster replication

The log file (LOG.NSF) provides helpful information for troubleshooting replication problems within a cluster.

Log file

To access the log, from the IBM® Lotus® Domino® Administrator, click the Servers - Analysis tab and select the log file for the server you want to check. Then check for replication problems in these views:

Tip You can also check replication events from the Replication tab in the Domino Administrator.

Edit the NOTES.INI file to include the Log_Replication setting, which allows you to display detailed replication information in the log.

Monitoring Configuration

The Monitoring Results database (STATREP.NSF) is a repository for pre-configured and custom statistics. It is created when you load the Collect task, if it doesn't already exist. You can set alarms for some of these statistics. For example, you might set an alarm to generate a Failure report when more than three attempted replications generate an error. You can also report statistics to any database designed for this purpose, although typically the database is the Monitoring Results database (STATREP.NSF).

Note that you can edit the NOTES.INI file to include the Repl_Error_Tolerance setting, which increases the number of identical replication errors between two databases that a server tolerates before it terminates replication. The default tolerance is 2 errors. The higher the value, the more often messages such as "Out of disk space" appear.

If you run the Event task on a server, you can set up an Event Monitor document to report replication problems. You can also create a Replication Monitor document that notifies you if a specific database fails to replicate within a certain time. To view events from the Domino Administrator, click the Server - Analysis tab, click Statistics - Events, and then view the desired report.

Replication history

The replication history for a database describes each successful replication of a database. To view the replication history of a database, select a database icon and choose File - Application - Properties (or File - Application - Replication - History).

Replication schedules

You can see a graphical representation of the replication schedules of the servers in your Domino system. To view replication schedules, from the Domino Administrator, click the Replication tab.

Replication topology maps

Create a replication topology map to display the replication topology and identify connections between servers. To view replication topology maps, from the Domino Administrator, click the Replication tab. You must load the Topology maps task before you can view a replication topology map.
