Target Authentication Best Practices Credential System

Do not set preferred credentials for group/common accounts, e.g., SYSMAN. The following SQL statement gives you the result of preferred credential setting:

SELECT

t.target_name,tc.user_name,tc.credential_set_name FROM MGMT_TARGET_CREDENTIALS tc, MGMT_TARGETS t WHERE tc.target_guid=t.target_guid

Keep track of the operations on credential by enabling auditing the corresponding actions

Use emcli verbs to synchronize credentials between Enterprise Manager and its database targets

emcli update_db_password

user_name=“DBUserName”

change_at_target=yes
