Understanding the SQL Server Compact Edition Server Agent Log

  • Artykuł

The Microsoft SQL Server Compact Edition Server Agent log file contains information about each replication synchronization and Push, Pull, or SubmitSQL in remote data access (RDA) operations. The log file, always called sqlcesa30.log, uses the following abbreviations to represent actions in replication and RDA operations:

  • Replication Session Control Block (RSCB)
    An automatically incremented structure that uniquely identifies each client's operation.

    When Sqlcesa30.dll is loaded, the RSCB begins at 1. Sqlcesa30.dll is unloaded only when Microsoft Internet Information Services (IIS) restarts, or the computer running IIS is restarted.
