The New Enterprise Manager Ops Center "Harvester" utility

Did you know that you can run Enterprise Manager Ops Center is a totally "disconnected" mode for networks that are detached from the internet?  There is a cool utility we call the "Harvester" that helps you do this and we've just put out a major upgrade to it.  

If you haven't used the Harvester before, here is a quick overview. It uses your credentials to log into My Oracle Support and download all of the patch meta data and other content you require and bundles it up into a nice, crisp tar ball ready to be moved onto your dark network and loaded into the Ops Center Enterprise Controller.  Once you've done this, Ops Center's patching and configuration management functions will work just as if it is attached to the internet.

Now, here's what's new in Harvester 2.0:

  • Major performance improvements - at least 8 times faster. This will allow customers to initiate and continually refresh their offline environments without having to wait for hours and days for the content to download.

  • Ability to download patches from a certain date - this will allow dramatic reductions in the size of the offline bundle customers have to carry with them to a dark environment.

  • Ability to download a customized, predefined list of patches - this will allow customers to download only certain patches that they deem important in their environment.

  • Support for incremental downloads - automatically flag which patches were downloaded in each run, allowing customers to copy only the new files to the disconnected EC.

  • Disk space optimization - a major complaint of customers is that the old Harvester created a huge TAR ballwhich made it frustrating to 1) create 2) transfer and 3) upload to the disconnected EC. The new Harvester resolves this issue on all levels.

  • Ability to run the Harvester on Linux - the old version only runs on Solaris.

  • Self auto update mechanism - allows customers to enjoy additional features and bug fixes immediately, without having to upgrade their EC.

  • Simplified user interface - special attention was given to simplifying the Harvester and disconnected process for new customers.

This new Harvester will be bundled with the next Ops Center update release, but will also work with all versions of 2.5 and 11g ECs.
