Oracle Enterprise Manager Configuration Guide Release 9.2.0 Part Number A96673-01 |
|
This section provides guidelines for determining storage requirements and disk space allocation for your Oracle Enterprise Manager repository.
Space requirements can vary greatly as a result of what Oracle Enterprise Manager tools you are licensed to use and the amount of data generated by the work you perform. In addition, the growth of the repository could vary slightly depending upon the database version in which the repository is created.
If you choose to create a new repository from a typical installation session and accept the default configuration for the repository, a new OEM_REPOSITORY tablespace will be created. The OEM_REPOSITORY tablespace contains repository objects for the Oracle Enterprise Manager Console and all separately licensable Packs regardless if you have installed or purchased licenses for them. In addition, depending on the database version in which the repository is created, the repository could initially allocate between 6 - 26 MB of hard disk space.
Depending on how you actually use Oracle Enterprise Manager products, the repository size may increase. To determine by how much your repository could grow, refer to the table below. To accommodate an increase in repository size, the default OEM_REPOSITORY tablespace is automatically configured to autoextend. For example, if you have created the default OEM_REPOSITORY tablespace which allocates 4 MB for using Capacity Planner for a single, small database, but you actually plan to use Capacity Planner on a more regular basis - for example, for three large databases - then you should expect the size of your repository to increase by approximately 16 MB. In such situations, the tablespace would autoextend automatically to accommodate the increase.
If you choose to create a new repository from a typical installation session and want to use an existing tablespace, follow these steps to determine how much disk space the repository will use:

For example, if you:
The total of all these space allocations (7 MB + 45 MB + 4 MB + 32 MB) is 88 MB. Thus, you should allocate approximately 88Mb for your repository.
