This chapter describes the minimum hardware requirements you must meet before installing Oracle Management Service (OMS), Oracle Management Agents (Management Agents), and Oracle Management Repository (Management Repository).
In particular, this chapter covers the following:
CPU, RAM, Heap Size, and Hard Disk Space Requirements for Oracle Management Service
CPU, RAM, and Hard Disk Space Requirements for Oracle Management Repository
Note:
The hardware requirements outlined in this chapter can relate to either physical or virtual hardware. If you are allocating virtual resources, you must ensure that the underlying physical hardware is not over subscribed and can support the allocated virtual resources.
Table 1-1 describes the minimum CPU, physical memory (RAM), heap size, and hard disk space requirements for installing an OMS (including a Management Agent that comes with it).
Note:
If you plan to have the OMS and the Management Repository on the same host, then meet the requirements described in Table 1-1 and Table 1-3, and make sure the CPU, RAM, and hard disk space requirements are a combination of the values mentioned in both tables.
Caution:
The requirements mentioned in Table 1-1 indicate the minimum configuration required at the time of installation. Understandably, over a period of time, depending on the use of Enterprise Manager resources, you might have to upgrade to a higher configuration than the one you maintained at the time of installation. For example, the hard disk space required at the time of installation is 18 GB, but depending on the use of Oracle Software Library, generation of log files, and so on, you might require more space eventually.

The physical memory mentioned here includes .5 GB of RAM required for Oracle BI Publisher. At the time of installation, if you choose not to configure Oracle BI Publisher, then the actual physical memory required can be .5 GB less than what is mentioned here.
The following are the minimum CPU, RAM, and hard disk space requirements for installing Oracle Management Agents (Management Agent), Hybrid Cloud Agents, and Hybrid Cloud Gateway Agents.
Caution:
The requirements mentioned in this section indicate the minimum configuration required at the time of installation. Understandably, over a period of time, depending on the use of Enterprise Manager resources, you might have to upgrade to a higher configuration than the one you maintained at the time of installation. For example, the hard disk space required at the time of installing a Shared Agent is 15 MB, but depending on its use, generation of log files, and so on, you might require more space eventually.
Note:
The CPU cores can be shared with other processes.
For a Hybrid Cloud Agent and for a Hybrid Cloud Gateway Agent, the requirements are the same as the requirements mentioned for a standalone Management Agent.

Table 1-3 describes the minimum RAM and hard disk space requirements for configuring a Management Repository:
Note:
If you plan to have the Management Repository and the OMS on the same host, then meet the requirements described in Table 1-3 and Table 1-1, and make sure the CPU, RAM, and hard disk space requirements are a combination of the values mentioned in both tables.
Caution:
The requirements mentioned in Table 1-3 indicate the minimum configuration required at the time of installation. Understandably, over a period of time, depending on the use of Enterprise Manager resources, you might have to upgrade to a higher configuration than the one you maintained at the time of installation. For example, the hard disk space required at the time of installation is 19 GB, but depending on the use of the Management Repository over time, you might require more space eventually.
