Recovery Performance

Recovery Performance

When you recover a session that reads durable subscription messages, the following factors can impact recovery performance:
  • Message priority.
    During recovery, the PowerCenter Integration Service processes new messages from the JMS publisher if the messages have a higher priority than the recovery messages.
  • Message volume.
    During recovery, the PowerCenter Integration Service processes all messages that the JMS publisher sent after the session failed. The JMS publisher can send a large number of messages between the time that the session fails and the time you recover the session.
