调度设施的设计不要求存放工具目录数据库和计划运行任务的 DB2 UDB 服务器是同一个服务器。

The scheduling facilities are designed such that the tools catalog database does not need to reside on the same DB2 UDB server where the tasks are scheduled to run.

youdao

工具目录数据库包含在 DB2 UDB 服务器上调度运行的所有任务的元数据（比如计划在每个周日早上一点钟运行的备份任务）。

The tools catalog database contains all the metadata about the tasks that are scheduled to run on the DB2 UDB server (for example, a backup task scheduled to run every Sunday at 1:00 a.m.).

在这种情况下，DB 2 UDB服务器上的调度程序需要连接到工具目录数据库，以便检索运行任务需要的信息。

In this case, the scheduler on the DB2 UDB server needs to connect to the tools catalog database in order to retrieve any required information about the tasks to be run.
