2 Meeting Hardware Requirements

This chapter describes the hardware requirements you must meet before installing Oracle Management Service (OMS), a standalone Oracle Management Agent (Management Agent), and Oracle Management Repository (Management Repository). In particular, this chapter covers the following:

• CPU, RAM, Heap Size, and Hard Disk Space Requirements for OMS

• RAM and Hard Disk Space Requirements for Standalone Management Agent

• RAM and Hard Disk Space Requirements for Management Repository

CPU, RAM, Heap Size, and Hard Disk Space Requirements for OMS

Table 2-1 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).

Table 2-1 CPU, RAM, Heap Size, and Hard Disk Space Requirements Per OMS

	Small	Medium	Large
	(1 OMS, <=1000 targets, <100 agents)	(2 OMSes for <=10,000 targets and <1000 agents)	(> 2 OMSes, >=10,000 targets, >=1000 agents)
CPU Cores/Host	2	4	8
RAM	4 GB	6 GB	8 GB
RAM with ADPFoot 1 , JVMDFoot 2	6GB	10 GB	14 GB
Oracle WebLogic Server JVM Heap SizeFoot 3	512 MB	1 GB	2 GB
Hard Disk Space	7 GB	7 GB	7 GB
Hard Disk Space with ADP, JVMD	10 GB	12 GB	14 GB

^Footnote 1 ADP Manager is Application Dependency and Performance

^Footnote 2 JVMD is JVM Diagnostics

^Footnote 3 Default heap size is 512 MB. For higher heap size, set the size manually.

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, so a total of 14 GB.

RAM and Hard Disk Space Requirements for Standalone Management Agent

Table 2-2 describes the RAM and hard disk space requirements for installing a standalone Management Agent:

Table 2-2 RAM and Hard Disk Space Requirements Per Standalone Management Agent

	Small	Medium	Large
	(1 OMS, <=1000 targets, <100 agents)	(2 OMSes for <=10,000 targets and <1000 agents)	(> 2 OMSes, >=10,000 targets, >=1000 agents)
RAM	512 MB	512 MB	512 MB
Hard Disk Space	1 GB	1 GB	1 GB

RAM and Hard Disk Space Requirements for Management Repository

Table 2-3 describes the RAM and the hard disk space requirements for configuring a Management Repository:

Table 2-3 RAM and Hard Disk Space Requirements for Management Repository

	Small	Medium	Large
	(1 OMS, <=1000 targets, <100 agents)	(2 OMSes for <=10,000 targets and <1000 agents)	(> 2 OMSes, >=10,000 targets, >=1000 agents)
CPU Cores/HostFoot 1	2	4	8
RAM	2 GB	4 GB	6 GB
Hard Disk Space	50 GB	200 GB	400 GB
