Bug #: 50004054 (SQL Hotfix); 50004028 (SQL Hotfix)

Microsoft distributes Microsoft SQL Server 2005 or SQL Server 2008 fixes as one downloadable file. Because the fixes are cumulative, each new release contains all the hotfixes and all the security fixes that were included with the previous SQL Server 2005 or SQL Server 2008 fix release.

SYMPTOMS

Consider the following scenario:
  • In Microsoft SQL Server 2005 or Microsoft SQL Server 2008, you set up a transactional replication.
  • The transactional replication contains some articles.
  • For one of the articles, you use stored procedures to deliver the insert command, the update command, and the delete command. For example, you set statement delivery to use Call <stored procedure> in the Article Properties window. Or, you specify the commands by using the @ins_cmd parameter, the @del_cmd parameter, and the @upd_cmd parameter of the sp_addarticle stored procedure.
  • For another article, you use Transact-SQL commands to deliver the statements.
  • You make some changes to the articles. The changes are delivered to the subscriber in the same execution batch.
  • The sum of the parameters that are required to deliver the batch exceeds 2,100.

    Note If you use SQL Profiler Trace to capture a trace, you may find the sp_executesql stored procedure for the batch that is called by Distribution Agent.
  • You synchronize the data.
In this scenario, some changes may not be replicated to the subscriber correctly.

Note You can verify that this issue occurs by using the table comparison tool (Tablediff.exe).

Additionally, the statement that occurs at the end of the batch is missed. By default, a batch contains 100 transactions.

Note You can view the replicated commands by using the sp_browsereplcmds stored procedure in the distribution database.

In this situation, if the missed statement performs an INSERT operation, a row may be missed on the subscriber. Then, if later DML operations occur on the missed row at the publisher, Distribution Agent fails, and you receive the following "error 20598" message:
The row was not found at the Subscriber when applying the replicated command.

CAUSE

Distribution Agent should detect if the 2,100 maximum parameter limit for stored procedures is exceeded. Then, Distribution Agent should move the overflowing commands to the next execution batch. However, because of a bug, the last command is skipped and is not processed.

RESOLUTION

SQL Server 2005 Service Pack 3

Note For push subscriptions, apply Cumulative Update 1 on the distribution server. For pull subscriptions, apply Cumulative Update 1 on the subscribers.

SQL Server 2008

The fix for this issue was first released in Cumulative Update 3. For more information about how to obtain this cumulative update package for SQL Server 2008, click the following article number to view the article in the Microsoft Knowledge Base:
960484 Cumulative update package 3 for SQL Server 2008

Note For push subscriptions, apply Cumulative Update 3 on the distribution server. For pull subscriptions, apply Cumulative Update 3 on the subscribers.

WORKAROUND

To work around this issue, use one of the following methods.

Method 1

Decrease the value of the CommitBatchSize parameter for Distribution Agent. Therefore, you can avoid exceeding 2,100 parameters per batch of committed transactions.

Method 2

Use the same command delivery mechanism for all articles in the publication. Avoid mixing the command delivery mechanisms for articles in the same publication.

To avoid error 20598

Error 20598 may occur as a side effect of this issue. To avoid error 20598, you can use the -SkipErrors 20598 switch. After you enable this switch, Distribution Agent logs the error and then continues to process the additional rows that have to be delivered. After Distribution Agent skips error 20598, data integrity remains compromised because of the missing row. You may have to delete the row and then insert the row again at the publisher to deliver the changes to all the subscribers.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
