In my last blog I mentioned “Step by step installation of OEM13c on Windows server”.

This blog contains all the hardware requirements for all three components. “Oracle Management Service, Oracle Management Agent and Oracle Management Repository {Database}

Mentioned below are the three different tables which will help you understand what all ammo {Hardware} is required before you leave for war.{OEM13c Installation}

NOTE: If you wish to install OEM13c on single host {both OMS and OMR (database) on single machine} than make sure you meet hardware requirments mentioned in TABLE 1 and TABLE 2 together.

Minimum CPU, RAM, Heap Size, and Hard Disk Space Requirements Per OMS

TABLE 1

  Evaluation or Simple Installation Advanced Installation (SMALL) Advanced Installation (MEDIUM) Advanced Installation (LARGE)
Deployment Size Evaluation or Simple Small Medium Large
Configuration 1 OMS, <100 Targets, <10 Agents, < 3 Concurrent User Sessions 1 OMS, <1000 Targets, <100 Agents, <10 Concurrent User Sessions 2 OMSes, >=1000 but <10,000 Targets, >=100 but <1000 Agents,>=10 but <25 Concurrent User Sessions 2 OMSes, >=10,000 Targets, >=1000 Agents, >=25 but <=50 Concurrent User Sessions 4 OMSes, >=10,000 Targets, >=1000 Agents, >=25 but <=50 Concurrent User Sessions
CPU Cores/Host

(Can be shared with other processes)

2 4 6 12 6
RAM

(With Oracle BI Publisher and JVMD Engine)

10 GB 10 GB 12 GB 24 GB 12 GB
Hard Disk Space

(With Oracle Software Library, Oracle BI Publisher, and JVMD Engine)

24 GB 24 GB 24 GB 24 GB 24 GB
Temporary Directory Hard Disk Space 10 GB 10 GB 10 GB 10 GB 10 GB
Oracle WebLogic Server JVM Heap Size 1 GB 1.7 GB 4 GB 8 GB 4 GB

Note:  The physical memory {RAM} 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.

Minimum CPU, RAM, and Hard Disk Space Requirements for Management Repository

TABLE 2

  Evaluation or Simple Installation Advanced Installation (SMALL) Advanced Installation (MEDIUM) Advanced Installation (LARGE)
Deployment Size Small Medium Large
Configuration 1 OMS, <100 Targets, <10 Agents, < 3 Concurrent User Sessions 1 OMS, <1000 Targets, <100 Agents, <10 Concurrent User Sessions 2 OMSes, >=1000 but <10,000 Targets, >=100 but <1000 Agents,>=10 but <25 Concurrent User Sessions > 2 OMSes, >=10,000 Targets, >=1000 Agents, >=25 but <=50 Concurrent User Sessions
CPU Cores/Host 4 6 12
RAM 7 GB 10 GB 18 GB
Hard Disk Space 23 GB

(SYSTEM: 600 MB, MGMT_TABLESPACE: 15 GB, MGMT_ECM_DEPOT_TS: 1 GB, MGMT_AD4J_TS: 3 GB, TEMP 3 GB, ARCHIVE LOG OFF)

147 GB

(SYSTEM: 600 MB, MGMT_TABLESPACE: 100 GB, MGMT_ECM_DEPOT_TS: 1 GB, MGMT_AD4J_TS: 10 GB, TEMP 10 GB, ARCHIVE LOG AREA: 25 GB)

455 GB

(SYSTEM: 600 MB, MGMT_TABLESPACE: 300 GB, MGMT_ECM_DEPOT_TS: 4 GB, MGMT_AD4J_TS: 30 GB, TEMP 20 GB, ARCHIVE LOG AREA: 100 GB)

649 GB

(SYSTEM: 600 MB, MGMT_TABLESPACE: 400 GB, MGMT_ECM_DEPOT_TS: 8 GB, MGMT_AD4J_TS: 50 GB, TEMP 40 GB, ARCHIVE LOG AREA: 150 GB

CPU, RAM, and Hard Disk Space Requirements for Oracle Management Agent, Hybrid Cloud Agent, Hybrid Cloud Gateway Agent

NOTE: Mentioned below in TABLE 3 are the different ways you can install Oracle Agent 13c, the hardware required will entirely depend on the method you adopt to install Oracle Agent. Please select accordingly.

TABLE 3

  CPU Cores Per Host

 

RAM Agent Base Directory Space Swap Space Temporary Directory Space Stage/Working Directory Space Agent Instance Home
Agent Installation Using the Add Host Targets Wizard or Any of the Silent Methods 2 512 MB 1.5 GB 500 MB 1 GB N/A Included as part of the Agent Base Directory space.  
Agent Cloning Using the Add Host Targets Wizard or Any of the Silent Methods 2 512 MB 1.5 GB 500 MB 500 MB N/A Included as part of the Agent Base Directory space.  
Agent Installation Using Agent Gold Images 2 512 MB 1.5 GB 500 MB 500 MB 750 MB Included as part of the Agent Base Directory space.  
Agent Gold Image Creation N/A N/A N/A N/A N/A 1 GB N/A  
Agent Gold Image Staging N/A N/A N/A N/A N/A 1 GB N/A  

 

I hope this will help you do design your server before you install Oracle Enterprise Manager 13c on that. Make sure you do meet minimum requirements as listed above in the three table, failing in same will result in Poor Performance and if unlucky your system might also get crash. It happened with me very first time. 😉

Play Safe…

Thanks
