Types of Replication System Problems

The types of problems that occur in a replication system roughly correspond to the different stages of development of the replication system. A replication system consists of Replication Server components (Replication Servers, Replication Agents, data servers, routes, connections) connected together such that data is copied reliably from source tables to destination tables.

• Configuration Problems
  Configuration problems occur during Replication Server set-up, such as when Replication Servers, RepAgents, and data servers are added to the replication system using rs_init.
• Subscription Problems
  Subscription problems occur when subscription materialization or dematerialization fails.
• Replication Problems
  Replication problems occur when data changes at the primary database are not applied to the destination database.
• Manual Recovery Problems
  Manual recovery problems occur during the recovery of a failed partition, truncated primary database log, primary database failure, or Replication Server System Database (RSSD).
