Handling Procedure

Check the database status of the active and standby management nodes.

1. Log in to the active and standby management nodes respectively as user root. Run the su - ommdba command to switch to user ommdba, and then run the gs_ctl query command to check whether the following information is displayed in the command output.

   Command output of the active management node:

    Ha state:  
           LOCAL_ROLE: Primary  
           STATIC_CONNECTIONS            : 1  
           DB_STATE                      : Normal  
           DETAIL_INFORMATION            : user/password invalid  
    Senders info:  
           No information

   Command output of the standby management node:

    Ha state:  
           LOCAL_ROLE: Standby  
           STATIC_CONNECTIONS            : 1  
           DB_STATE                      : Normal
