The Software Library is a very important and critical “core” part of Oracle Enterprise Manager . It is a file system repository associated with the Enterprise Manager system, and the prime purpose of this library is to store various software entities used by Enterprise Manager – such as Software patches, Reference gold images, Deployment procedures, Virtual appliance images and so on. This can be seen in the screenshot below (choose Enterprise.. Provisioning and Patching.. Software Library from the Enterprise Manager console after you have logged in to Enterprise Manager as an administrator with appropriate privileges, such as a super-admin or as a provisioning/patching operator or designer): The software library is used extensively by Enterprise Manager components and functions – for e.g., by the Self-update capability of Enterprise Manager, and also by Enterprise Manager jobs, procedures etc. Here are some set up tips. As a general best practice, use the ‘ OMS Shared File System ’ storage option for best performance as compared to the other option of ‘ OMS Agent File System ’. In the case of a multi-OMS setup, make sure that the shared file system is mounted between all OMS servers as a storage location. For this purpose, the supported file systems are - NAS Storage via NFS (this is the recommended option), ACFS or ZFS, or DBFS. For sharing on Windows, use the recommended OCFS2 cluster file system. In the case of large software entities to be stored in the Software Library, you can consider using ‘ Referenced File Locations ’ to save time and space. This capability, first added in Enterprise Manager Cloud Control 12c, allows you to stage large files to existing hardware in your data center – such as file servers or web servers or storage systems. In effect, the software Library entities refer to files stored on other servers. However, referenced file locations are read-only for the purpose of the software library. Such locations will not be used to upload files. For this purpose, use the option of “Upload File Locations”.
