Troubleshooting Tools (Replication)

Troubleshooting Tools (Replication)

In addition to the tools listed above, the following tools can be used to troubleshoot replication.

Data validation

Transactional and merge replication allow you to validate that data at the Subscriber matches data at the Publisher. Validation can be performed for specific subscriptions or for all subscriptions to a publication.

Validating Replicated Data

tablediff utility

The tablediff utility is used to compare the data in two tables for non-convergence, and is particularly useful for troubleshooting non-convergence in a replication topology. This utility can be used in conjunction with validation: if validation indicates that data at the Publisher and Subscriber do not match, the tablediff utility can be used to identify which rows do not match; it can also generate Transact-SQL to bring the Publisher and Subscriber into convergence.

System Monitor

System Monitor provides a number of counters associated with replication agents and can be used to troubleshoot replication performance.

Monitoring Replication with System Monitor

SQL Server Profiler

SQL Server Profiler is another tool that can be used to troubleshoot replication performance. You can capture and save data about server events to a file or table to analyze later. For example, you can monitor a replicated database for stored procedures or other processes that are taking a long time to complete.

Introducing SQL Server Profiler

Error and event logs

Microsoft SQL Server logs certain system events and user-defined events to the SQL Server error log and the Microsoft Windows application log. Use the information in the SQL Server error log to troubleshoot problems related to replication.

Monitoring the Error Logs

Error Reporting

The Error Reporting feature is enabled by default. If a fatal error occurs in the SQL Server Database Engine, in SQL Server Agent, or in Analysis Services, a report is automatically sent to Microsoft. The information provided by Error Reporting can also be useful if you need to contact customer support.

Error and Usage Report Settings

SQLdiag utility

The SQLdiag utility is a general purpose diagnostics collection utility that can be run as a console application or as a service. You can use SQLdiag to collect logs and data files from SQL Server and other types of servers, and use it to monitor your servers over time or troubleshoot specific problems with your servers. SQLdiag is intended to expedite and simplify diagnostic information gathering for Microsoft Customer Support Services.
