Prior to reading the online transaction logs, the Extractor requested a list of active VLFs for the specified database from Microsoft SQL Server but failed to execute the DBCC LOGINFO command. After this warning, the Extractor continues to read the online transaction logs but determines the VLFs directly from the log. This Extractor behavior might degrade performance and cause a delay when processing the online transaction logs. For Microsoft SQL Server Express Edition sources, the Extractor always determines the VLFs directly from the log.
