Reconfigure Oracle Enterprise Management Tool orcale Enterprise Manager (OEM)

Source: Internet
Author: User

Due to Database Server IP changes and other issues, the need to re-build the OEM for Oracle 10g basic process.

First, you must know the Instance name, port, and SYS password, and then perform the following steps:

1. Change the password of Dbsnmp to clear old configuration-related roles, users, and synonyms.

2. Use the ECMA command to recreate the configuration information (emca-config dbcontrol DB-repos recreate)

3. check em running status (emctl status dbconsole)

4. Access the management page through the new em address

The interaction process on the console is as follows (the comment is in the black body ):
