Grid computing in oracle 10g

Hello Everybody :) I want to make an application which will be added to grid computation (it will be inverting a matrix with dimension 1000x1000 in loop with lenght of 999999 ).
I have got few questions.
1 How to make grid?? I' ve used Oracle 10gXE for making an application and I know it quite well, but I can't find anything obout making a grid (how to do it). Do I have to install Oracle Application Server 10g or oracle Enterprise MAnager 10g? If I have to, how to do grid (do I have to make clustres or does the grid will be made automatically when I give IP adresses for the server)? I have got 3 computers in LAN network, 1 of them has got Oracle 10gXE.
2 the application inverting the matrix is written ic C++. How to add this application to grid computing using SQL (I want to see the result of computing in C++ application)?
Do I have to use something like ODBC in C++?
3 If points 1 & 2 have got solutions for me (I hope so) is there any chance for remote control for grid computing (I want to control grid computing from applicayion i C++)?
Thank You very much for all answers
Marcin Migdal from Poland
here is my e-mail [email protected]

OK I have also read that if I want to make grid computing I need following things.
1 Oracle databade 10g which provides computing
(Express Edition is a standalone databse such as Access but it has multithread and is used standard applications such us sample application in XE (shop,forums etc.) )
2 Oracle Application server but I don't know if I need it couse it can be useless if I've got database
3 Oracle Enterprise manager 10g Grid Control

Install Oracle 9i client on a computer with Oracle 10g Client

Hello all!!
I'm using a computer with Oracle 10g client, and I access two databases. One server has Oracle 10g server, and the other server has Oracle 9i server.
I want to install 9i client, to have it also in my computer. I haver read that I just have to install it in a different ORACLE_HOME, but I have a doubt.
If I install 9i client, would I be able to use the utilities, (exp, expddp, sqlldr) of both versions, or which version will be used in the command line for the utilities.
Thanks a lot!!!

To start with, Home Selector is a "9i thing" (and older), in 10g there's the OUI -> Installed Products... -> Environment tab instead.
About the 9i dbca with other Oracle products installed. If you use launch.exe to start via dbca start menu shortcut, it uses ora92\assistants\dbca as working directory ("start from"). So when not looking for "numbered dlls" like oracore9.dll, a later/different version will be loaded if earlier in path, since loading goes through jre directories, ora92\assistants\dbca, then the dir's from path variable. From there it may start to link in libraries from different homes (on my laptop, "launch.exe dbca" uses files from 2 additional home paths!)
But, if you instead use dbca.bat started from ora92\bin, it will look in the right directories first and there's no dll mess-up. (But only when using the correct cwd!)
Plain and simple: stay very far away from multiple-general-home installs. It is possible to install allright, in different homes and all very nicely, but there will be pain when you decide to use the stuff (perhaps with sql*plus as the only exception, but I've run into bugs with that too).

Grid Concept in Oracle 10g

Hi everyone!!!
what is Grid in Oracle 10g ? How Grid works ? How is it beneficial (I am not asking for additional features of 10g , but advantage of Grid over non grid vesions (prior to 10g) ) .
Thanks.......Have a nice DAY!!!!

Grid computing

Very Good morning experts ;
I need some information about grid computing. Oracle 10g is first grid based database.
Grid technology , how it acts really ?
Getting bit confused from following term.
Grid computing enables the creation of a single IT infrastructure that can be shared by multiple business processes.

A grid, or cluster, is a logical computer processing platform that consists of a number of physically hardware resources.
Oracle RAC consist of the follow basic infrastructure components:
multiple database server platforms
a public network for accessing these platforms and/or cluster
a private network (called an Interconnect) between these platforms as a high-speed communication cluster backbone (server platforms need to coordinate cluster processing, resources, and so on)
a shared I/O fabric layer (typically fibre) to a storage system that provides the cluster's data storage (same cluster storage disks are available for I/O on each and every server platform - NAS is also used)
Oracle RAC is a shared-everything-cluster. This means that if you have access to a single cluster server, you have access to all the database resources and data available on that cluster database.
Other database cluster technology makes certain database cluster resources available via certain cluster servers only. If that resource (e.g. table, schema, datafile, etc) is only available on a single server, and that server fails, that cluster resource is no longer available.
With Oracle RAC you can loose any cluster server - without loosing any cluster resources. The same data and resources are available on each and every cluster node. A server failure will not result in a client no longer being able to access specific rows, or tables, or schemas.

What exactly is the Grid in oracle 10g

Please anybody can help on this.
Thanks
ARIZ

There are many definitions of 'Grid computing'. And when you pick a working definition, you will find there are many products and product features that can be said to support that definition.
I suggest your read Oracle's "Technical White Paper: Grid Computing with Oracle" found here to get their definition and at least part of their product and feature list.

Sun grid engine interface with 10g grid services

Hi,
I am a Graduate student in Comp Science. for my parallel class I am looking at interfacing sun Grid engine with Oracle 10g services.But I could not find ant API in oracle for me to use globus or any other oracle native API to call the job scheduling ( or even job submitting) functions in 10g. could any one please enligten me on this.I saw a marketing paper on Oracle globus development kit.But could not find any technical documentation on that regard.
thanks,
saji

Hi Sajindra,
Check out the Unified scheduler feature of Oracle Database 10g. Unified scheduler allows you to submit jobs that can be both database jobs or non-database jobs (i.e. executed outside the database).
cheers,

Is oracle 10g really oriented for grid computing?

Hello all,
Microsoft's article "http://www.microsoft.com/sql/prodinfo/compare/oracle/mythandreality.mspx" reads as follows:
"Oracle's purported Grid enablement in 10g is based on its Oracle Real Application Clusters (RAC) technology that is no more than a local cluster. RAC is a local cluster of computers with no geographic distribution capabilities. This marketing campaign relabeled existing features to exploit current industry trends. "
is microsoft article right? why o why not is oracle grid is a local cluster instead of grid computing oriented?
Thanks in advance.
Hernán.

The distance limitations are not due to the RAC product itself but rather network technology limitations.. Unable to deliver data between sites at a very high speed.
I think Oracle is the only product available in the market today that can provide a close to Grid solution. Its also important to note that Grid computing in general is not ready because there are no set standards for heterogeneous systems to communicate with each other.. for example we cannot have Windows and Linux as a clustered configuration. While these limitations do affect the overall Grid strategy, there is definitely a grid within the Oracle paradigm. meaning an Oracle Grid does exist.

Oracle Database 10g Express Edition support Grid Computing ?

Hi
May I know if I install the Oracle Database Express Edition on Linux, which Linux O/S
that can support Grid Computing ?
And if I install this database on Windows, which Windows platform that support Grid Computing ?
Thanks.
Vivi

Hi.
What do you mean by support Grid?
I'm assuming you are actually asking about support for RAC. If so, then:
- Oracle XE does not support RAC.
- There are a number of Linux distributions that are supported for RAC, including Red Hat Advanced Server and SUSE Linux Enterprise Server. Basically, if it is free, Oracle don't support it. That's not to say it doesn't work, but it's not supported.
- I guess the only sensible Windows choice is Windows 2003. It would work in Windows 2000 or XP, but these aren't sensible options as both are very old and one is a desktop OS.
These answers also apply to the Grid Control.
Cheers

Oracle 10g on windows - RAC & grid ?

From the materials that I have read, got to know that Grid computing concept exploits uses RAC technology and few others like ASM, Transportable Tablespaces, distributed SQL features, Oracle Streams etc
So, what is Grid Control Management ?
Grid Control Management CD is not avaible for Windows yet
(not listed in - http://otn.oracle.com/software/products/oem/index.html)
But 10g RAC for windows is available
Foll document specifies installation details for the same http://otn.oracle.com/pls/db10g/db10g.to_toc?pathname=..%2F..%2Fhtml%2FB13829_01%2Ftoc.htm&remark=portal+%28Getting+Started%29
So, I think I can configure 10g RAC on Windows and thus can get the basic configuration of grid done
Only thing is I won't be having any utilities or GUI tools etc to control the grid
Am I right ?
Please let me know the details
Thanks

What is missing, I suspect, is reading the installation docs.
http://docs.oracle.com
If that doesn't work then come back and ask specific requestions referencing the appropriate document and naming the actual version you are trying to install (ps 10g is a marketing name not a version number).

Grid And RAC in oracle 10g

Hi Experts,
I'm new to Grid And RAC implementation.
Is there any good links which I can learn the basics and implementation methods of Grid.???

Grid computing is a concept. Wikipedia has a fairly decent description at http://en.wikipedia.org/wiki/Grid_computing and there is even an infocenter on the concept at http://www.gridcomputing.com/
Oracle leans toward the 'Utility Computing' idea in that wiki. This is especially true in the Oracle Application Server (subject for a different forum). In that mode of Grid, you add or drop out instances of programs as demanded by the load, just like you would add or drop electrical generators on the power grid.
Taking generators off line permits maintenance, reduces wear and tear when the beasts are idle, and allows the minimum number of fully-loaded generators (and therefore minimum support personnel, support expenses) to be used as compared to lots of partially used ones - why not do that with computers as well?
In the database world, Oracle provides RAC as a coordinated cluster of database instances. The cluster may be grown or shrunk, not without some care, in a fashion similar to the power generators.
And just as with the electrical generators, people have to design the new instance, manage how and when it is added to or taken off the cluster, even figure out how to balance the load across the various units. Once designed, and put in place, it is relatively easy to add or remove an instance from the RAC, and (if done correctly) there is a minimum disruption to running applications.
Be aware that the analogy is less-than-perfect.
I recommend getting the Apress book Pro Oracle Database 10g RAC on Linux: Installation, Administration, and Performance as the basic manual for understanding and learning RAC. Read that and then use the demos and examples from Howard's site at http://www.dizwell.com and Jeff's setups at http://www.oracle.com/technology/pub/articles/tech_dba.html#linux And finally, go through the RAC material at http://www.oracle.com/technology/tech/grid/index.html

ORACLE 10G: Grid or not?

The following is an excerpt from Ian Foster's article on What is a Grid?.
<....coordinates resources that are not subject to centralized control
(A Grid integrates and coordinates resources and users that live
within different control domainsfor example, the users desktop
vs. central computing; different administrative units of the same
company; or different companies; and addresses the issues of
security, policy, payment, membership, and so forth that arise in
these settings. Otherwise, we are dealing with a local management
system.)>
My main point of confusion is that going from ORACLE 10G's capabilities, especially with new features like the 10G Database ASM, Streams, Transportable Tablespaces, 10G Application Server APM, Workload Management and all of 10G Enterprise Manager Grid Control array of features, systems built on this infrastructure cant be referred to as a grid, atleast from the foregoing excerpt.
Please can someone put me right, assuming i am going wrong. I am researching into grid technology and where Oracle technology fits.
Thank you.

Hi,
you shouldn't confuse - Oracle Grid is just hype
but seriously this one is enterprise grid computing or
computing on demand or utility computing.
It's different from academic (classics) grid.
Main goal of enterprise grid - reduce TCO of datacenters.
It's based on usual "idiots" report of Gather (or may
be IDS) that server's CPUs are too underload (idle).
So you should dynamically distribute workload between
few servers in RAC cluster (now named as Grid).
And of course, it will be work automagically
so bosses can fire all datacenter's personnel
and manage just push one red button.

Is Oracle Grid Computing a product or concept

I have read some of the threads and I have a basic question.
Does oracle have a comprehensive infrastructure grid product that actually takes servers, storage, network, and provide a provisioning system that one can install a operating environment and software products etc. If it does not have such a product then what is the deal about "oracle grid compute"
I have gone through the OEM 10gR2 install guide, I'm not too sure this mentions about grid computing. ASM comes close as far as storage is concerned, but what about CPU,RAM, Network and OS.
I also got that part that oracle products are ready for the grid - which product is not ready in that sense. The Grid should enable any Op Env and consequently any product - unless ofcourse they (OS) are still under test.

When someone talks about grid computing, I think of a system where I can seemlessly bring systems in and out of use at will to support the requirements at that time. So if I have 10 servers, in the morning I might want to run 6 app server nodes and 4 database nodes, whilst at night I might want to run 2 app server nodes and 8 database servers. The same kit serving different functions to meet the business demands.
Oracle does not provide this type of functionality. It allows you to add and remove nodes from a cluster (database and app server), but the seemless mix and match approach is not possible in a real environment.
The Grid Control allows you to monitor and manage your whole infrastructure, but this doesn't really warrant the "Grid" tag in my opinion. It is only an evolution of the OEM Management Server available in previous releases, and that was never given the "Grid" title.
I guess everyones definition of grid computing is slightly different. Oracle doesn't meet my definiton, but it may surpass the definition used by others.
Marketing aside, the 10g Database is a erally cool bit of kit :)
Cheers

How to setup Oracle 10g grid on a node other than SERVER

Hi,
We are in a process of moving the database residing on Windows servers to IBM AIX5L servers. For this purpose I came up with an idea of installing database on AIX and operate it remotely on Windows platform using 10g Grid Control and 10g Client. For this to happen perfectly, I am in middle of implementing same concept on Windows platfrom. I have made a test database on a Windows based server and I am trying to connect it with another Window based node. I know hwo to connect it using a client software but I am more interested to do it on Grid Control.
At this stage, I have created database on server and have also configured Oracle Management Agent along with Oracle 10g Grid Control. I read oracle documentation that it is necessary to install Oracle Management Agent on server machine in order to let other nodes get connected with the server.
I would extremely appreciate anyone who could help me in setting up 10g grid control on another node. Please note I wish to operate the database using grid control remotely. For know you can consider both computers on same network, I will go on VPN once I am able to do it on local network.
Looking forward for your reply
Shez

Hi Xaheer,
Thanks for looking into this matter. I had agent and grid running on the server and I have almost installed 10g Grid control 10.2.0.2. The place where I am stuck now is the OMS Configuration script that run after the installation in Configuration Assistant window. It just stuck here for some minutes and then displays the error. Let me paste here the lines in that appears in the detail panel of installation wizard.
Output generated from configuration assistant "OMS Configuration"
Command = oracle.sysman.emcp.oms.OmsPlugIn -configureOms
Operation Stopping OPMN Processes is in progress.
Operation EM Deploying is in progress.
Operation Creating OMS Respository is in progress.
Configuration assistant "OMS Configuration" failed
The "d:\OracleHomes\agent10g\cfgtoollogs\configToolFailedCommands" script contains all commands that failed, were skipped or were cancelled. This file may be used to run these configuration assistants outside of OUI. Note that you may have to update this script with passwords (if any) before executing the same.-----------------------------------------------------------------------------
According to the oracle installation guide, I had to deconfigure the database before running the setup. I did it using this command,
emca -deconfig dbcontrol db -repos drop
AS far as i think, I am getting this error becouse of sysman schema which was droped during the installation and was recreated( as I read in the oracle installation guide ) is not found by the script. So in order to b ring back sysman schema, I recreated the repository using following commands.
emca -deconfig dbcontrol db -repos drop
emca -config dbcontrol db -repos create
Now, the database on server is not starting up. I can just see RED downword error, u know what i mean right ? Everyting is down, Database instance, Listener and Agent Connection to Instance, and on the top pf page I can see " Enterprise Manager is not able to connect to the database instance. The state of the components are listed below."
When I try to startup the database using the grid control it gives me this error.
Couldnot contact the agent. Verify that the url for the agent is null.
I am stuck in here. If you know how to fix this agent , i would really appreciate that.
Thanks

Error while installing Oracle 10G Grid control in RHEL

I was installing Oracle 10G Grid control in RHEL. Got the following error. Any idea what this means and what is the remedy?
=======================================
Output generated from configuration assistant "Oracle Net Configuration Assistant":
/home/oracle/jre/1.1.8/bin/../bin/i686/native_threads/jre: relocation error: /home/oracle/jre/1.1.8/bin/../lib/i686/native_threads/libjava.so: symbol __libc_wait, version GLIBC_2.0 not defined in file libc.so.6 with link time reference
Configuration assistant "Oracle Net Configuration Assistant" failed
=======================================
regards,
Anjan

I saw this once but I forgot how I solved it. I believe that I made a softlink to the libc.so.6 from another libc. Have a look on Metalink, becauses I've got the idea for my solution there.
