SYMPTOMS

Consider the following scenario. In an instance of SQL Server 2000, you configure a transactional publication or a merge publication. You upgrade the instance of SQL Server 2000 to SQL Server 2008. When you try to open Replication Monitor in SQL Server Management Studio, you receive the following error message:
Msg 515, Level 16, State 2, Procedure sp_replmonitorrefreshdata, Line 386
Cannot insert the value NULL into column 'isagentrunningnow', table 'distribution.dbo.MSreplication_monitordata'; column does not allow nulls. INSERT fails.
The statement has been terminated.

CAUSE

This issue occurs because the isagentrunningnow column in the MSreplication_monitordata table does not allow NULL values after you upgrade the instance to SQL Server 2008.

RESOLUTION

The fix for this issue was first released in Cumulative Update 3 for SQL Server 2008 Service Pack 1. For more information about this cumulative update package, click the following article number to view the article in the Microsoft Knowledge Base:

Note Because the builds are cumulative, each new fix release contains all the hotfixes and all the security fixes that were included with the previous SQL Server 2008 fix release. Microsoft recommends that you consider applying the most recent fix release that contains this hotfix.

By default, any hotfix that is provided in a SQL Server service pack is included in the next SQL Server service pack.

WORKAROUND

To work around this issue, run the following statement to set the isagentrunningnow column to allow NULL values:
ALTER TABLE MSreplication_monitordata
	ALTER COLUMN isagentrunningnow [bit] NULL
