The process for applying updates is essentially as follows:
Check for the latest updates available from Oracle.
Download the updates you want to apply to the Software Library.
Apply the update.
Review the following sections to learn how to apply an update:
Updates must be downloaded to the Software Library (the local store) before they can be applied. You can review the latest available updates from the Self Update console.
Note that Enterprise Manager must have access to the Enterprise Manager Store via the Internet to download available updates. If this access is not possible, you can download entities in offline mode. See Applying an Update in Offline Mode for details.
Under certain circumstances, such as in high security environments, an active Internet connection between Enterprise Manager and the Enterprise Manager Update Store may not be available. In such situations, the Self Update feature can be used in offline mode.
The update process still requires that a computer exist at your site that has Internet access, as a connection to the Enterprise Manager Update Store is still required to obtain the updates. Update files from this computer can then be transferred to a computer behind your firewall.
The generic offline mode update procedure is as follows:
emcli import_update_catalog
command to import the file into the Oracle Management Service instance or the Management Agent you want to update.
