4 Meeting Hardware Requirements

This chapter describes the 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.

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

Table 4-1 describes the 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 4-1 and Table 4-2, and make sure the CPU, RAM, and hard disk space requirements are a combination of the values mentioned in both tables.

Note:

While installing an additional OMS (by cloning an existing one), if you have installed BI publisher on the source host, then ensure that you have 7 GB of additional hard disk space on the destination host, over and above what is mentioned in Table 4-1.

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

The following are the 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.

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

Table 4-2 describes the RAM and the 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 4-2 and Table 4-1, and make sure the CPU, RAM, and hard disk space requirements are a combination of the values mentioned in both tables.
