Setting Credentials for the Job System to Work with Enterprise Manager

Windows systems require that you set the correct credentials for the Jobs system to work properly in Enterprise Manager. By default, the Management Agent service is installed as a LocalSystem user. When submitting jobs, such as stopping or starting the database, the user submitting the job must have the Log on as a batch job privilege enabled.

Perform the following steps to establish that privilege for any operating system user who needs to submit an Enterprise Manager job.

1 .  Start the Local Security Policy tool:

      Windows 2000: From the Start menu, select Control Panel, Administrative Tools, then Local Security Policy.

     Windows 2003: From the Start menu, select Administrative Tools, then Local Security Policy.

     Windows XP: From the Start menu, select Control Panel, Administrative Tools, then Local Security Policy.

     Windows Vista: From the Start menu, select Programs, Administrative Tools, then Local Security Policy.

2.   Under the Security Settings list, expand the list to Local Policies.

3.   Under Local Policies, double-click User Rights Assignment.

4   Under Policy, search for the "Log on as a batch job policy".

在安装ORACLE的用户或组添加到这里就可以了。
