39.1 Description
The adbstart command starts the HADB server. If the multi-node function is used, executing the adbstart command on a node that has been disconnected from the multi-node configuration returns that node to the running multi-node configuration.
The HADB server's startup mode is as follows:
-
Normal start if the HADB server's previous termination mode was normal termination
-
Restart if the HADB server's previous termination mode was forced termination or abnormal termination. When the HADB server is restarted, recovery processing is performed on any transaction whose processing was underway at the time of the termination.
This command can also be used to specify the HADB server operation mode as an option. The four HADB server operation modes are as follows:
-
Normal mode
-
Quiescence mode
-
Offline mode
-
Maintenance mode
For details about the HADB server operation modes, see HADB server operation modes in Starting and terminating the HADB server and its operation modes in Scheduled Operations in the HADB Setup and Operation Guide.
The SQL statements and commands that can be executed depend on the HADB server operation mode. For details, see 39.3 SQL statements and commands that can be executed in each HADB server operation mode.
