Abstract
Architecture for replicating a database through log shipping. A replication service replicates data using one or more new internal application program interfaces (APIs), a replay configuration API which abstracts configuration information for each destination (or target) instance. APIs for log file management as part of the replication process are provided for opening communications for log shipping, tracking success of log shipping and closing out log shipping communications. Log shipping APIs are also provided for log truncation control. A ship control object is provided as a base class which includes an API for other components of the replication service to operate on log files when the log files are placed into a log directory. The ship control API is utilized by the replication service and for interaction with storage system log files.
