Message Options

The Plan Optimization Options panel allows you to request that optimization messages be produced by CA Datacom/DB when SQL queries are prepared or executed. These are diagnostic messages that are written to the MSG table. You can view them online using the Display Messages PF key or you can query the MSG table through online CA Dataquery or in DQBATCH.
