  • Session level

    sys tenants and all user tenants can execute the SHOW VARIABLES statement or query the SYS.TENANT_VIRTUAL_SESSION_VARIABLE view (Oracle-compatible mode) or the information_schema.SESSION_VARIABLES view (MySQL-compatible mode) to obtain the value of a session system variable.

• Modify variables

  • Global level

    • sys tenants can directly modify the value of a global system variable.

    • MySQL user tenants must have the SUPER or ALTER SYSTEM privilege to modify the value of a global system variable.

Usage notes

At session startup, the session wait_timeout value is initialized to the value of the global wait_timeout or interactive_timeout variable, depending on the client type. The client type is determined by the CLIENT_INTERACTIVE option in the mysql_real_connect connection options. For more information about the wait_timeout variable, see wait_timeout.

Examples

Set the number of seconds the server waits for activity before closing an interactive connection to 28800.

• Session level

  obclient> SET interactive_timeout = 28800;
  

• Global level

  obclient> SET GLOBAL interactive_timeout = 28800;
