16.4.3 HADB server operation modes when the multi-node function is used
On the master node, you can use the adbchgsrvmode command to change the HADB server operation mode.
In the case of a slave node, its HADB server operation mode is always the quiescence mode. Therefore, you cannot execute the adbchgsrvmode command.
In addition, to check the HADB server operation mode, execute the adbls -d srv command on the node running the HADB server you want to check. For details, see 10.2.3 HADB server operation modes.
Note that if a master node switchover occurs, the HADB server operation mode is carried over to the new master node.
