Oracle10g Grid Vs RAC

Oracle 10g : Grid computing is the combination of computer resources from multiple administrative domains for a common goal.
VS.
RAC: Oracle RAC allows multiple computers to run Oracle RDBMS software simultaneously while accessing a single database, thus providing a clustered database.
What are the major differences? Doesn't Oracle 10g (Grid) computing provides the features/functions of RAC ? as its name says Grid Computing?

You can have grid without RAC
RAC without grid
or both.
Why, year after year, they keep confusing a perfectly clear and simple message ... confuses me too.Sir, I have read this in oracle documents too.... Interviewer asked me this question in interiview, but I could not explain.
Sir, if we can have grid without RAC then why we need RAC ?
I think with only RAC we can have multiple instances accessing the single database/datafiles. Whereas with GRID we can not have such feature/functionality.

RAC database cannot be connected after Grid and RAC DB have been installed

Folks,
Hello. I am installing Oracle 11gR2 RAC using 2 VMs (main VM rac1 and slave VM rac2) with Oracle Linux 5.6
according to the website http://appsdbaworkshop.blogspot.com/2011/10/11gr2-rac-on-linux-56-using-vmware.html
Grid and RAC database have been installed successfully for both VMs rac1 and rac2. I am using the slave VM rac2 to test Grid and RAC database.
I have run the commands as below:
[ora11g@rac2 bin]$ pwd

Its output: cannot connect to the server at https://rac2.localdomain:1158/em
As we see the outputs for commands above, Grid is running at the beginning but now is not running. SQLPLUS and SQLdeveloper cannot connect with database. Browser url cannot connect to the console https://rac2.localdomain:1158/em.
My question is:
Do any folks understand how to solve the above 4 problems ?
Thanks.

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

Will Oracle9i Dataguard broker work with Oracle10g Grid control ?

Hello all,
I have recently configured Oracle9i dataguard using Dataguard broker and it's currently working fine but I am not sure if this could be managed with Oracle10g Grid control as it does for Oracle10g dataguard (i.e. Switch-over, Protection mode switching and so on ..)
I would appreciate if anyone could enlighten me further on this as I have not been able to find any proper document to provide me with the appropriate answer .
Thanks..

Ram,
For your JBCL questions:
JBCL 2.0 WILL be included in the production release of JDeveloper
2.0, but will not be visible on the palette by default. You can
add it back in if you really want to use JBCL.
For more info on this decision and why we are recommending Swing,
over JBCL see the post titled 'Which Oracle JDeveloper 2 GUI Lib
for database access' dated March 26. It includes plenty of
detail.
As for your gridControl question:
You can use a picklist with a gridcontrol, but there's not an
'automatic' way to do it (i.e. via the properties sheet). You
need to create a new rowsetinfo object that contains your query
for the picklist. Then bind this rowsetinfo object to a Swing
list control or combobox control. Finally, you need to hook the
list control to the cell of the grid you want the list to appear
in.

Oracle Grid Infrastructure / RAC Provisioning

Using the OEM GC Provisioning and Automated Patching Pack, you are able to provision a complete Oracle RAC Cluster, including the Grid Infrastructure and creation of an ASM Instance and a RAC Database.
In this paper I show an example of how I was able to do the provisioning of Grd Infrastructure and Oracle RAC on a 2 node OracleVM Cluster.
http://oemgc.wordpress.com/2010/07/14/oracle-grid-infrastructure-rac-provisioning/

Good one mate, I have recently installed OEM 11g on 2 nodes, and I am expected to set this (provisioning) up on OEM 11g soon, documents like this come in definitely handy, have seen your site too, looks very good and informative, thanks and keep writing.

•Case 2: Patching Oracle RAC or Oracle RAC One Node Database Homes
•Case 3: Patching GI Home Alone
•Case 4: Patching Oracle Restart Home
•Case 5: Patching a Software Only GI Home Installation
•Case 6: Patching a Software Only Oracle RAC or Oracle RAC One Node Home InstallationHere we in bit confussion which case we need consider case 3 or case 5.
We are haing another PSU 9 patch for oracle also.
Please help me how to proceed .
Thanks & Regards,
Venkata Poorna Prasad.S

Hi Venkata,
Case 3 you need to being down complete database as it will patch all node of the cluster by reading cluster configuration files from Grid Infrastructure.
Case 5 you can patch each node locally keeping other cluster db nodes up

Hi All,
I want to install Oracle 10g Release - 2 RAC (2 Node) on HP-UX 11.23 using OCFS-2. Please send me a link or docs which describes about step by step instruction of OCFS-2 and RAC on HP-UX 11.23.
Thanks,
Subhankar

Subhankar,
Check this link out
http://download.oracle.com/docs/cd/B19306_01/install.102/b14202/toc.htm
and make sure you have met all the pre-requisites (patches to install oracle on hp-ux 11- you can refer to oracle domentation for the required patches.
Aslo, if you have access to metalink you can refer to this Doc ID: Note:182177.1 Step-By-Step Installation of RAC on HP-UX. Actually this was created for 9i but it will give you a general idea.

How to install oracle10g grid control

hi
i want,how to install oracle10g grig control on windows...
i installed Db server 10g R2..

Installing Oracle10g Grid Control - - - management service hostname

Oracle 11g R1 RHEL 4 64bit
Grid Control 10.2.0.4
HI All,
I am installing the Oracle agent and when I get to the 'Specify Oracle Management Service Location' screen it asks for the 'Management Service Host Name'. Is this the same as my database server hostname? I'm not sure what to put here. When I do put the database server hostname in, then it says it can't locate port 4889 on that server. However, if you keep going through the install everything succeeds in the end. BUT, when I go to the link http://<management_service_hostname>:4889/em then nothing shows up. I am new with grid control. Anyone have any ideas?
Thanks.

Great. Thanks for your reply Bobcatalog!
Now I just want to get this all cleared up before I proceed with the installation. So here is what I am thinking of doing and please tell me if I am wrong, missing something or should do it another way.
1. Install OEM Grid Control 10.2.0.3 on a new host (server) which has nothing on it (i.e. no Oracle products - - - clean host) and then patch it to 10.2.0.4.
- I will use the create new database option, which will create the EM Repository database
- I will (or it will) install the OMS as well as the OMA (Oracle management Agent)
(Question: Should I install OEM Grid Control on just a regular filesystem or use ASM with it? I heard that there are issues with using ASM. If it will increase my chances of failure, then I will stay away from it...even though all our environments (DEV, PROD, QA) use ASM.
2. Install the OMA agent on each of the database servers (which are called 'targets') that I want to monitor.
And that is all that I will need to do, correct?
Thank you.

Cannot Startup Grid in 11gR2 RAC after Install Grid Successfully

Folks,
Hello. I am installing Oracle 11gR2 RAC using 2 VMs (main VM rac1 and slave VM rac2) with Oracle Linux 5.6 according to the website http://appsdbaworkshop.blogspot.com/2011/10/11gr2-rac-on-linux-56-using-vmware.html
Grid and RAC database have been installed successfully for both VMs rac1 and rac2.
I am using the slave VM rac2 to test Grid and RAC database because rac1 disk is full.
The problem is that OCR file is not available or currupted in the slave VM rac2.
I have created a pfile and add entry in the file sqlnet.ora in the slave VM rac2. By now, I still cannot startup Grid as below:
[ora11g@rac2 /]$ cd u01/app/grid/bin/
[ora11g@rac2 bin]$ crsctl status resource

I have checked that there is no the file init+ASM2.ora in the directory '/u02/11g_db/ora11g/dbs'.
As we see the outputs above, my question is:
Can any folk help to solve the issue to start up Grid ?
Thanks.

Folks,
Hello. Thanks a lot for replying. Let's analyze 3 cases as follows:
Case 1:
If don't export ORACLE_SID=+ASM2, the output is below:
[ora11g@rac2 /]$ cd u01/app/grid/bin
[ora11g@rac2 bin]$ ./sqlplus / as sysdba

ORA-15077: could not locate ASM instance serving a required diskgroup
SQL> startup pfile='/u01/app/grid/dbs/pfile'

Case 2:
If export ORACLE_SID=+ASM2, the output is below:

[ora11g@rac2 bin]$ ./sqlplus / as sysdba
SQL*Plus: Release 11.2.0.1.0 Production on Tue Mar 27 12:41:33 2012

SQL> startup pfile='/u01/app/grid/dbs/pfile'
ORA-01031: insufficient privileges
SQL>
Case 3:
Now, as you indicated, I export ORACLE_SID=racdb2, the output is below:
[ora11g@rac2 bin]$ pwd
/u01/app/grid/bin
[ora11g@rac2 bin]$ export ORACLE_SID=racdb2
[ora11g@rac2 bin]$ ./sqlplus / as sysdba
SQL*Plus: Release 11.2.0.1.0 Production on Tue Mar 27 12:33:48 2012

SQL> startup pfile='/u01/app/grid/dbs/pfile'
ORA-01031: insufficient privileges
SQL>
As we see the ouputs above, export ORACLE_SID=racdb2 doesn't have any effect. My question is:
Can any folk help to solve the above 3 issues to start up Grid ?
Thanks.

RAC VS GRID

Dear all,
what's the difference between GRID and RAC if any?
I know that services in RAC is a key component of GRID but i need a broader definition
Thanks

Note that I said "RAC is Oracle's implementation of
grid computing for the database'.
Specifically meaning that there are other components
of grid, even in Oracle technology stack. However,
the database component of grid (that which uses
several disparate resources to provide compute power
to manipulate database) is called RAC. I did note what you wrote. That's why I wrote what I wrote in reply.
Are you saying that Resource Manager isn't a "database component". Or ASSM? Or ASM? Or ASMM? Or LMT?
I would say that they are all database components. They all "manipulate database". And they are thus all part of Oracle's implementation of grid computing for the database.
What you are saying is that RAC is Oracle's implementation of grid computing for the database. I'm saying, it's just one component of an entire database-specific set of technologies which, taken together, represent an implementation of grid computing for the database.
That's a clear difference between us and it doesn't help to blur it away by pretending I didn't read what you wrote closely enough.
Therefore I request you quote the entire phrase and
use it as intended ...Well, no. Because it's cumbersome. We're on an Oracle forum; discussing Oracle; and discussing Oracle's implementation of grid-like technologies. I think that's plenty enough context in which it is clear that 'grid computing' means 'grid computing as it relates to database use and administration'.
And yes, Resource Manager is one of the technologies
that may be used to CONTROL the resources in the RAC.
But it is not the multi-resource coordinating
piece.It is central to "grid computing for the database". It doesn't just "control" it. It makes the transparent operation of database computing power a reality: Just as everyone switching on their kettles at the ad break during a tv movie premier is the cause of extra powerstations starting up and handling the peak load transparently for the tea-brewer, so RM's ability to scale people down and scale them back up means the RAC (or the single instance) provides appropriate computing power for queries transparently.
And it can be used to good effect *without RAC*. That is the point, of course. You go around oversimplifying and claiming that RAC=GCFTD (no, I won't keep quoting the entire lumbrous phrase. It's why I simplified as I did) and I think you do people a grave disservice. You underplay what grid is, what Oracle's implementation of grid is, what it can do for people and the fact that gridness (in any context) is a spectrum of possibilities, not a black and white issue.
And the 'does not mean transparency to
administrators' is taken in the same way as in a
power grid - to the user of electricity, the source
of the electricity (which gen station) is completely
transparent, but to the administrator it is not [as]
transparent. Yes, I realise that. That's why I just said it's a spectrum of possibilities. Glad to discover that you agree with me. But my point is that it's a spectrum of possibilities for users AND administrators, no exceptions. That different groups will "feel" any given point on that spectrum in different ways is obvious, but that the spectrum applies to all should be equally obvious ...but didn't seem to be from your earlier comments.

Hi Anil,
It says some library packages are missing .Did u check the cluster verify utility on all nodes in RAC? Its very mandatory. If not, Install all required packages on all nodes in a cluster and then try again.

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
