It’s been a few months since I did an install of Oracle Enterprise Manager 11g. I am however talking about some experiences from a real world implementation that I performed a while back at the UKOUG’s Management and Infrastructure SIG on the 27th. (you can book for this event here ) I thought therefore that it made sense to revisit the install again.
For those that don’t know EM 11.1 is built upon Weblogic Server 10.3.2. This is a new technology for Oracle DBA staff and is updated by means of the Smart Update Utility. This utility has to be invoked during the installation of a base weblogic server for Grid control because there are some mandatory patches. The installation guide and various guides you’ll find on the internet talk about using smart update to download those patches from Oracle Support. This isn’t too much of a hassle in my view since you’ll want to allow internet communications with Oracle Support for your OMS server anyway to get the most out of the product.
I duly downloaded WebLogic Server, installed the base product and then ran Smart Update. The very first dialog box presented to me asked me to update the updater (and that happens far too frequently these days in my opinion). This I did. I then reran the updater, but there is now no option for obtaining patches from Oracle Support. It turns out that this is a new feature in Smart Updater 3.3.0, rather than download patches through the updater, all patching is essentially offline. The process is now.
- log into MOS via a web browser
- find and download the patches you require
- copy them to the patch cache directory for each instance of Weblogic Server you have (this can be on shared storage)
- manually unzip the patches
- run the patch updater and it will detect the patches and allow application.
