Replication Agent may fail if it cannot read the primary database log.
An instance of Replication Agent for Oracle or Replication Agent for Microsoft SQL Server may fail to function properly on Windows if User Account Control (UAC) is enabled and the instance is not started with the Run as administrator option. This problem occurs when Replication Agent does not have permission to read the primary database log on Microsoft Windows Vista, Microsoft Windows Server 2008, Microsoft Windows Server 2008 R2, and Microsoft Windows 7. The Replication Agent system log file may contain messages indicating a problem accessing the primary database log:
java.io.FileNotFoundException: C:\SOMEPATH\REDO01.LOG (Access is denied)
Failed to synchronize log device with message C:\SOMEPATH\MSSQL\DATA\pdb_log.ldf (Access is denied)
