Full and Partial Data ExtractsBecause syndicated data loading does not use EIM to maintain synchronization between the server and the remote databases, you must force a resynchronization step at the end of each direct load. Force resynchronization either by re-extracting an entirely new remote database for each mobile user or by performing a partial extract that includes only the refreshed syndicated data. A new, full database extract creates a database snapshot file for a given mobile user. A partial extract contains only S_SYND_DATA table data. Some users receive syndicated data updates once a week, while some might receive syndicated data updates monthly or quarterly. Therefore, partial extract is preferred. Possible Data LossSometimes remote users connect to Siebel Server using unstable dial-up connections that prevent the data file from being transferred correctly, so that the data file does not reach the remote server. Siebel Server does not verify that the data file reached its destination successfully. At the end of the transfer step, Siebel Server removes the data file from the server. In the case in which a data file is lost and removed from the server, you must extract a new data file for users. CAUTION: The loss of data or files can occur without warning. You might not be able to automatically determine the success or failure of a particular transfer. As a result, sales representatives might be using incorrect data for up to several months without realizing it. |
