The following request can be used to place a checkpoint entry into a journal table:

     CHECKPOINT account_db.jnl_table, NAMED daily_pay_maint;

When this request is executed, all update activity is ceased on tables that write journal images to the journal table, (jnl_table) and an event number is returned.

A row containing the daily_pay_maint label is placed into the journal table. The label can then be used in rollforward or rollback operations.
