Starting with Oracle Database 10g, Enterprise Manager (EM) has integrated the Oracle MetaLink support vehicle for up-to-date patch advisories and notifications. From the EM home page, under the Critical Patch Advisories subheading, you can access and configure the Oracle MetaLink Credentials link to register your environment for this service. In order to register your environment, you will need a valid CSI (customer support identifier) with MetaLink. Log in as SYSDBA to perform the registration. When you click the Not Configured link, you will be directed to the Patching Setup screen, shown in Figure 21.1, to enter your MetaLink user ID and password.
