This section discusses the configuration parameters used with HotStandby.
There are four types of parameters:
▪Server-side parameters in the server-side solid.ini configuration file
▪There are two HotStandby-specific sections in the server-side solid.ini configuration file: [Cluster] and [HotStandby].
▪Various other parameters can also affect HotStandby functionality.
▪Client-side parameters in the client-side solid.ini configuration file
▪High Availability Controller (HAC) configuration parameters in the solidhac.ini configuration file
▪High Availability Manager (HAM) configuration parameters in the HAManager.ini configuration file
Tip: If you use the Watchdog sample provided with the solidDB® package, the solid.ini will also contain watchdog-specific parameters in a [Watchdog] section. For information, see the section Watchdog sample.
Access mode
The access mode of a parameter defines whether the parameter can be changed dynamically, and when the change takes effect. When the value of a parameter is changed with an ADMIN COMMAND, the change might not apply immediately, nor the next time that the server is started. If a parameter value is written to the solid.ini file, it will take effect the next time that the server starts.
Access mode values
The possible access modes are:
▪RO (read-only): the value cannot be changed; the current value is always identical to the startup value.
▪RW: can be changed through an ADMIN COMMAND, and the change takes effect immediately.
▪RW/Startup: can be changed through an ADMIN COMMAND, and the change takes effect the next time that the server starts.
▪RW/Create: can be changed through an ADMIN COMMAND, and the change applies when a new database is created.
