If RECOVER_DETAILS YES is present in the server configuration file when the server is started, the server logs the time spent for each phase of recovery to the server status log. This option provides a way to more specifically monitor the progress of automatic recovery. The server writes the entry for each recovery phase upon completion of that recovery phase, so the current recovery phase can be determined by examining the contents of the server status log.
See the section "Server Startup Hangs or Takes Excessive Time" of this document for more details on monitoring automatic recovery.
