EXAMPLES
Display Current Value
wsrep_provider_options
define optional settings the node passes to the wsrep provider.
To display current wsrep_provider_options
values:
SHOW GLOBAL VARIABLES LIKE 'wsrep_provider_options';
The expected output will display the option and the value. Options with no default value, for example SSL options, will not be displayed in the output.
Set in Configuration File
When changing a setting for a wsrep_
Options are set in the my.cnf
configuration file. Use the ;
delimiter to set multiple options.
The configuration file must be updated on each node. A restart to each node is needed for changes to take effect.
Use a quoted string that includes every option where you want to override the default value. Options that are not in the list will reset to their default value.
To set the option in the configuration file:
wsrep_provider_options='socket.ssl_cert=/path/to/server-cert.pem;gcache.debug=YES;gcs.fc_limit=NO;socket.send_buf_size=NO;evs.keepalive_period=PT3S'
Set Dynamically
The socket.ssl_cert option cannot be set dynamically. It can only be set in the configuration file.
Trying to change a non-dynamic option with SET
results in an error:
ERROR 1210 (HY000): Incorrect arguments to SET
