gpactivatestandby

1. Description

The gpactivatestandby tool can activate the Standby instance and use it as a new Master instance of the MatrixDB cluster. The user must run the tool on the Standby host to activate.

After Standby is activated to become the new master, there is no new Standby in the MatrixDB cluster. Users need to regenerate using the gpinitstandby tool.

2. Parameter options

Parameter name	Description
-a	Do not prompt the user to confirm.
-d standby_master_datadir	Absolute path to the activated Standby data directory. If this option is not specified, the $MASTER_DATA_DIRECTORY environment variable setting will be used.
-f	Use this option to force activate Standby. This option can only be used if it is determined that Standby and Master are consistent.
-l logfile_directory	Directory to write to the log file. The default is ~/gpAdminLogs.
