原文: SQL Server 作業(yè)監(jiān)控

在講解SQLServer Agent Jobs之前，先要講解msdb。

Msdb是SQLServer的系統(tǒng)數(shù)據(jù)庫之一，用于存儲SQLServer的配置、元數(shù)據(jù)等信息。包括：

l? SQLServer Agent Jobs,Job Steps,Job schedules,Alerts,Operators,等等。

l? Service Broker,Log Shipping,Backups/restore信息,維護計劃、數(shù)據(jù)庫郵件、基于策略管理信息等等。

l? SSIS包。

在這部分，主要集中在msdb的以下部分：

l? Job setup/configuration Information

l? Job Execution Information

l? Job Step(s) Setup/Configuration Information

l? Job Step(s) Execution Information

l? Schedule Information

SQLServer 允許在Replication,SSIS,存儲過程,批處理上創(chuàng)建和執(zhí)行各種自動化任務。允許使用GUI 或者T-SQL腳本創(chuàng)建。這些信息存儲在msdb中。SQL Server Agent Job Setup andConfiguration Information：

可以在SSMS中執(zhí)行以下腳本查找作業(yè)信息：
