dbug

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 Dynamically

Changes made dynamically with SET GLOBAL are not durable and will be lost when the server is stopped. To be durable, changes must be set in the configuration file.

The dbug option can be set dynamically using the SET GLOBAL command. Setting wsrep_provider_options dynamically does not change the value of other wsrep_provider_options.

To set dbug dynamically:

SET GLOBAL wsrep_provider_options='dbug=NO';

To dynamically set multiple options in a single statement:

SET GLOBAL wsrep_provider_options='dbug=NO;cert.optimistic_pa=NO';
