"system summary information" section from status command says that host is down when is it up and replication is working. There are no errors in the event_log and data is flowing. Is there a problem?
"system summary information" section gets its information from file statusdb, which often contains outdated information. As a result most of the time "system summary information" section contains old information.
command sp_ctrl>clear status all clears some error messages from statusdb but not all. Unfortunately there is no way to clear every thing under "system summary information" section unless you run ora_cleansp, but these messages will return once the config file is activated and there is interruption in connection between source and target.
The event_log and the top section of the status commands will signal if there is a problem. If the event_log does not show any errors and data is replicating then ignore everything under "system summary section". If you are writing a script to monitor shareplex then just have it skip that section.
