The Software Library: Admnistration page
One important point to be aware of when creating your Software Library is that you need to ensure that the
location you create the Software Library in is accessible from each OMS, if at some stage you believe your EM12c
deployment will require some level of high availability. This can be achieved by using the same network file system
(NFS) share mounted on each OMS, or any other technology that allows sharing file systems between machines.
The EM12c release includes several new features related to the Software Library:
•
In this release, the Software Library becomes the single location for a lot more entities, such
as directives and assemblies. (These new entities are explained in Chapter 5.) Many of these
entities are self-updateable, so we now have integration with Self Update.
•
Oracle has also expanded the storage-type support, so you now have support for NFS
filesystems being shared between OMSs as well as any filesystem that we can reach (that is,
agent filesystems can now be used to host the Software Library as well).
•
Referenced locations are now supported for the Software Library, so if you have a centralized
location for serving these entities that is separate from the OMS, you can now reference those
via HTTP, NFS, and so forth. In this case, the OMS stores the metadata about where this
referenced location is, and the software bits are stored externally.
•
A range of other capabilities exist in this release. You can, for example, attach support notes
or readme files to Software Library entities. The library includes improved search capabilities,
and of course the new privilege model allows the use of fine-grained privileges for entity
access.
Management Tools
So right about now, you're probably asking, “Well, what about all those other management tools that Oracle has?”
Often you'll find there's some level of confusion about what all these tools are, how to differentiate between them,
and of course when to use which one. Let's spend some time discussing that now.
First, the main point of differentiation between Cloud Control and the other Oracle management tools such as
Database Control (DB Control) and Fusion Middleware Control (FMW Control) is the architecture. Cloud Control is
designed to manage your entire data center, and as such it has a much more robust, multi-tier architecture than you'll
find in the other tools.
