2 Meeting Hardware Requirements

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:

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.

WARNING:

Do not install Enterprise Manager Cloud Control 12c on servers of SPARC series: T1000, T2000, T5xx0, and T3-*. For more information, see My Oracle Support note 1590556.1.

2.1 CPU, RAM, Heap Size, and Hard Disk Space Requirements for Oracle Management Service

Table 2-1 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 2-1 and Table 2-2, 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 2-1 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.

2.2 CPU, RAM, and Hard Disk Space Requirements for Oracle Management Agent

The following are the minimum CPU, RAM, and hard disk space requirements for installing Management Agents.

  • For a standalone Management Agent, ensure that you have 2 CPU cores per host, 512 MB of RAM, and 1 GB of free hard disk space.

  • For a Master Agent, ensure that you have 2 CPU cores per host, 512 MB of RAM, and 1 GB of free hard disk space.

  • For a Shared Agent, ensure that you have 2 CPU cores per host, 512 MB of RAM, and 15 MB of free hard disk space.

Note:

The CPU cores can be shared with other processes.

2.3 CPU, RAM, and Hard Disk Space Requirements for Oracle Management Repository

Table 2-2 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 2-2 and Table 2-1, 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 2-2 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.
