Termination of cold standby configuration |
Normal termination of cold standby configuration |

This is the normal termination mode. When HA Monitor's monend command is executed after the adbstop command has terminated normally in the active system, the HADB server terminates normally, and then the cold standby configuration terminates normally. |
Normal termination |
|
2 |
Forced termination of cold standby configuration |
monend |
When only HA Monitor's monend command is executed in the active system, the HADB server is terminated forcibly, and then the cold standby configuration is terminated forcibly. |
Forced termination |
|

3 |
Abnormal termination of cold standby configuration |

When operations cannot be continued due to an error, the HADB server is terminated immediately without waiting for completion of the current transaction. If there is no standby system, the cold standby configuration is terminated abnormally. |
Abnormal termination |

Occurrence of hot standby |
Normal termination of HADB server in the active system |
