Question

我有一个4节点的全局集群。在每个节点上，我有一个从SQL作业调用的存储过程，该作业使用PowerShell获取服务器名称。（PowerShell脚本不能在作业中工作，但可以作为sql脚本工作。）根据名称，我调用一对备份作业，一个用于备份数据库，另一个用于事务日志。其中两台服务器位于北方，两台服务器位于东方。两个数据库备份作业似乎都运行了两次。请让我知道我需要更改什么才能让这个存储过程只调用一次作业。非常感谢提前!!!

这是我得到的错误：

Message
Executed as user: Domain\User1. SQLServerAgent Error: Request to run job Backup_DB - FULL - North (from User Domain\User1) refused because the job is already running from a request by User Domain\User1. [SQLSTATE 42000] (Error 22022).  The step failed.

这是给我错误的存储过程：

我遇到的问题是，在每个NetBackup作业中，我创建了相同的.bch文件。因此，当t-logs备份作业启动时，它将创建一个名为Backup123.bch的文件。然后，当完整备份作业运行时，它将尝试创建相同的.bch文件并提供错误"the job is already running."。

最重要的是，一旦我更改了Veritas要创建的每个作业的.bch文件名，该过程就会按预期工作。

存储过程以根据服务器名称运行作业
