RAC Installation ---- Hardware Requirment Doubt

Hi All,
I have to install 10g RAC at home for learning purpose. I have two PC's with same version of
linux (Oracle Enterprise Linux 32 bit each) installed, but having different hardware. One machine is laptop and
other is desktop. So, will it be possible to install RAC on these machines. Is it a pre-requestie to have same
hardwre at both machines.
Please give your valuable suggestions.

Hi,
You can istall RAC with the combination of Desktop and Labtop. You need NIC cards for both the Machines. You need shared storage. for that You can use either scsi disks or fireware disks. To use fireware you need fireware slots on both the machines. There are two ethernet cards you need one for Private interconnect between the nodes and one for Public. and you need switch, Then you have to connect the shared storage in fireware slots. You need to install the clusterware, before that you can use Openfiler to partition the disk or anything to partition the disk for ocr and votingdisk etc. Then you can install the ASM for Filesystem and Volumemanger for disk and Fra group. Then you can install enterprise agent if you want to use enterprise manager grid control. Then you can install software.

RAC Installation Requirements

Hi Gurus
We would be thinking to install RAC for new application.
My requiremets are as follow.
These are all general requirements and no specific to OS and any thing
1> What could be the Hardware requirements (Like Nodes should be same hardware or change can also possible in RAC)
2>Software requiremets (Like what all softwares are required for installing RAC,Any software depedency)
3>Network requirement
and last one
Can i have different node in RAC as 1 node running in London and other in New York ?
Thanks in Advance !!!!!!
Regards

You should be able to find most of your answers in the "Oracle® Real Application Clusters
Installation Guide" - for 11g R2, that document can be found here. See Chapter 1 Section 2, "Overview of Server Hardware, Network and Operating System."
Although not required, ideally you would want the hardware configuration of each node to be identical. However, it is entirely acceptable for the hardware configuration of each node in the cluster to be configured differently (different number of CPUs, physical memory, etc.). Oracle recommends that the Operating System release/version/patch level be the same on all nodes in the cluster.
As for your question regarding the distance between nodes in a cluster, there is the concept of a "[Stretch Cluster|http://www.google.com/search?source=ig&hl=en&rlz=&q=oracle+stretch+cluster&aq=f&oq=&aqi=g1]," whereby nodes in a cluster can be placed up to a finite distance apart from one another to prevent situations where the loss of a data center takes out both/all nodes. The distance between London and New York likely exceeds the limitation for a stretch cluster, though. You could perhaps consider having two clusters: One in New York and one in London and having Data Guard set up between them. ;-)

Can any one say that list of hardware for 11gr2 2node rac installation? thank in advance

can any one say that list of hardware for 11gr2 2node rac installation? thank in advance

Hi ,
Hardware Requirements
Physical memory (at least 1.5 gigabyte (GB) of RAM)
An amount of swap space equal to the amount of RAM
Temporary space (at least 1 GB) available in /tmp
A processor type (CPU) that is certified with the release of the Oracle software being installed
A minimum of 1024 x 786 display resolution, so that Oracle Universal Installer (OUI) displays correctly
All servers that are used in the cluster must have the same chip architecture, for example, all 32-bit processors or all 64-bit processors
Adequate disk space in the software installation locations to store the Oracle software
You need at least 5.5 GB of available disk space for the Grid home directory, which includes both the binary files for Oracle Clusterware and Oracle Automatic Storage Management (Oracle ASM) and their associated log files, and at least 4 GB of available disk space for the Oracle Database home directory, or Oracle home directory.
About Shared Storage
These Oracle Clusterware components require the following disk space on a shared file system:
Three Oracle Clusterware Registry (OCR) files, 300 MB each, or 900 MB total disk space
Three voting disk files, 300 MB each, or 900 MB total disk space
If you are not using Oracle ASM for storing Oracle Clusterware files, then for best performance and protection, you should use multiple disks, each using a different disk controller for voting disk file placement. Ensure that each voting disk is configured so that it does not have share any hardware device or have a single point of failure.
Network Hardware Requirements
When you configure the network for Oracle RAC and Oracle Clusterware, each node in the cluster must meet the following requirements:
Each node must have at least two network interface cards (NIC), or network adapters. One adapter is for the public network interface and the other adapter is for the private network interface (the interconnect). Install additional network adapters on a node if that node meets either of the following conditions:
Does not have at least two network adapters
Has two network interface cards but is using network attached storage (NAS). You should have a separate network adapter for NAS.
Has two network cards, but you want to use redundant interconnectsIn previous releases, to make use of redundant networks for the interconnect, bonding, trunking, teaming, or similar technology was required. Oracle Grid Infrastructure for a cluster and Oracle RAC can now make use of redundant network interconnects, without the use of other network technology, to enhance optimal communication in the cluster. This functionality is available starting with Oracle Database 11g Release 2 (11.2.0.2).Redundant Interconnect Usage enables load-balancing and high availability across multiple (up to 4) private networks (also known as interconnects).
However, When you install Oracle software, Oracle Universal Installer (OUI) automatically performs hardware prerequisite checks and notifies you if they are not met.

Questions on the Hardware requirement mention in the 12c installation guide

Hello experts,
I have a confusion on the Hardware requirements mentioned in the 12c installation guide where they mentioned as below.
RAM with ADP1, JVMD2 8 GB 12 GB 20 GB
1 ADP Manager is Application Dependency and Performance
2 JVMD is JVM Diagnostics
Question 1: what does this RAM with ADP or JVMD mean. is it just the additional RAM space required in the server or does is that special requirement ??
Oracle WebLogic Server JVM Heap 1.7 GB 4 GB 8 GB
Size
Question 2: What is this JVM Heap size ? how do we configure this in the server ??
Thanks in Advance for your Help.

Hi,
#1: It means if you also want to install ADP and JVMD, the total RAM required is a small (e.g. < 1000 targets), medium (e.g. > 1000 targets and < 10000 targets), large EM deployment (e.g. > 10000 targets) is 8 GB, 12 GB, 20 GB, respectively. That is the memory requirement for an OMS host.
#2: The heap size for the OMS java process. You can adjust the heap size by changing the -Xmx<heapsize> (see an example below) in the following file:
<middleware_home>/gc_inst/user_projects/domains/GCDomain/bin/startEMServer.sh
An example of OMS heap size setting of 2048 MB:
if [ "${SERVER_NAME}" != "EMGC_ADMINSERVER" ] ; then
USER_MEM_ARGS="-Xms256m -Xmx1740m -XX:MaxPermSize=768M -XX:-DoEscapeAnalysis -XX:+UseCodeCacheFlushing"
if [ "${JAVA_VENDOR}" = "Sun" ] ; then
if [ "${PRODUCTION_MODE}" = "" ] ; then
USER_MEM_ARGS="-Xms256m -Xmx2048m -XX:MaxPermSize=768M -XX:-DoEscapeAnalysis -XX:+UseCodeCacheFlushing -XX:+UseConcMarkSweepGC -XX:+UseParNewGC -XX:+CMSClassUnloadingEnabled -XX:CompileThreshold=8000 -XX:PermSize=128m"

Hardware requirement for Fusion Applications HCM installation

Hi Team,
I want to install fusion applications for HCM.
Can any one suggest the minimum hardware requirement for installation.
Please help me with any documents.
Thanks,
Chandra

Dear Chandra,
Please note that Fusion Applications installation involves following components.
1. Oracle Identity and Access Management components (Middleware infrastructure)
2. Oracle Database for IDM
3. Oracle Database for Fusion Apps
4. Fusion Applications Domains (includes Admin and managed servers for Fusion Applications)
I have posted a guide on installing Fusion applications on 2 node setup and if you have sufficient hardware to host 2 VMs then it can be done on single server as well.
http://www.oratraining.com/blog/2013/03/oracle-fusion-applications-installation-step-by-step-guide-11-1-6/
This will explain the 2 node architecture which I have prepared.
http://www.oratraining.com/blog/2013/03/fusion-applications-architecture-for-2-node-setup/
The minimum memory requirement changes if you select more products since in Fusion apps each products have their own domain and if you select more products then there will be more application managed servers (even if you don't select a product family, it will still create some managed weblogic servers based on dependency with selected products)
The minimum memory requirement to host IDM and consolidated DB in 1 node is 10-12 GB
The minimum memory requirement to host Fusion Applications domains on 2nd node is 64 GB (for 1 product family, for all products selected then 128 GB)
Please note that these are "minimum" requirements based on my experience, not as per the documents since what we are talking about is installing for "learning", not for production, where you will host various components in separate nodes.
Thanks

Hardware required for RAC setup at home

Hi All,
Could you please suggest the Hardware required for practicing RAC at home.
Regards,
VN

Hi, "user7202581",
For practicing purposes, you could consider a VBox / OVM based setup at home. We have used those for Hands On Labs in the course of Oracle Open World more than once. I recommend you use a machine with at least 8GB memory and dual core (HT enabled) processors. Some configuration examples: Lenovo Laptop, ThinkPad, 8GB, 320GB HDD, i5 dual core, 2.5 GHz, Win 7 or a Mac Mini, latest version, i5 dual core, 2.3GHz and 8GB memory would do the trick for a two node cluster. Note that I mention the hosting OS in case you use VBox. For OVM based setups you either have to use a dual boot system or use a dedicated machine. You will be somewhat restricted with respect to the hardware failures you can impose on this system obviously (due to the VM setup), but for practicing purposes, you should find those environments sufficient, I think. Also see: RAC on OVM templates: http://www.oracle.com/technetwork/server-storage/vm/rac-template-11grel2-166623.html
Hope that helps. Thanks,
Markus

Hardware Requirements for Android Adobe Air Installation or certification requirement?

Hi, Friends,
I am newbie on Adobe Air and tried to install Air apk on my android ICS device from Google Play.
However, it complains that the device is not compatible with the software package.
I wonder if there are any hardware requirements or certification requirement for new android phone device on the market.
Regards
-Charles

Well, my theory is it only works on 4g phones, at least with Metro PCS phones!
Using the following 3g phones, I got "device is not compatible"
- Hawai ascend OS (3g) ~incompatible
- HTC (3g) ~incompatible
- Samsung Admire (3g) ~incompatible
But after buying my $300+ 4g LG phone, also from Metro PCS, the Adobe AIR installed sucessfully.
Also, I as fyi, noticed that Adobe Air app did not show up in the Google play list on the 3g phones.
I hope this info helps.

The requirements depend on the operating system and the database used for the installation.
Go to http://service.sap.com/instguides -> SAP Netweaver -> Release 04 -> Installation -> SAP Web AS -> SAP Web AS 6.40 SR1 and Related Documentation -> Choose your database (Ex: Oracle ) -> Planning and Preparation -> Select SAP Web AS ABAP for Windows.
Look at Page 37, minimum RAM is 1 GB (because XI is Unicode), ABAP system 25GB.
You should check the same for Web AS Java also.
one more small thought...
You also need to find the how the end user will access your system. In case an end user access outside of the LAN (say via WAN or dial-up) using https, it will have additional requirements for your hardware as you will need compression enabled for improved response time for WAN. Adding compression or SSL may add additional hardware if you based your sizing based on LAN.
And also One easy approach is after you define your test case, run some load test on your QA/Staging system. Use the load test data and find out the hardware requirements based on load test. If your requirement is larger than the staging system, you may have to take a staged approach. In that case you roll-out the system to a certain number of users and monitor the system and plan for additional users based on the monitored results.
Also for RAM memory, HDD size you can check this document:

Oracle 11gr2 RAC installation

Hi Gurus,
In new project we have proposed to have 2 nodes single site RAC database Oracle 11gR2 64 Bit . We are going to have OEL 5.4 64 Bit Linux as OS and IBM as machine .
We are migrating standalone 10g R2 database to 11r2 Rac and from HP-UX to OEL Linux . We are migrating from different datacenter .
What would be the pfile configuration (i mean memory size doubles ) in RAC ?
We are going to use IBM storage . Need light on followings . Pls help me out
1>Requirements for installation
2>Grid installation requirements
3>ASM instance is physical database instance or just service ?
4>Any oracle document for installation of 11gR2 Grid and RAC?
If you provide me authorized links of RAC installation that would be better .
Thanks & Regards

And this is as a valid answer as any other to your question. You can run Oracle 10g XE on a notebook. You can run Oracle 10g Enterprise on a 64 CPU HP Superdome. You can run Oracle 10g RAC on a 60 blade servers, each with 8 dual-core CPUs and 64GB RAM.
So what is the best configuration? That depends entirely on WHAT you are planning to do using the Oracle RDBMS product. And it should be a concern that your approach is thinking that Oracle RDBMS is like Microsoft Excel and you can quickly and easily determine am optimal h/w and RAM config for it. Oracle RDBMS is not a desktop product like Excel. You do not fit h/w to it. You fit h/w to your requirements - as you would fit your choice of Oracle products to use to your requirements.
