Revisar Planes de Mantenimiento Base de datos
Muchas veces necesitamos consultar rápidamente como se encuentran configurado los planes de mantenimineto de una base de datos de forma rápida y ágil sin necesidad de tener que abrir el ambiente gráfico y tener que ver cada uno de los planes de mantenimentos que tenemos configurado en nuestro entorno de base de datos.
La manera más sencilla es consultando la tabla [msdb].[dbo].[sysschedules] en la base de datos msdb. El problema es que existen una series de campos que si no conocemos el significado, nos dejará un poco confundido con la información que estamos consultando.
