Need to understand basics of Oracle RAC and Grid technology, for training

I need to understand Oracle RAC and Grid infrastructure, from a manager's / training perspective.
I see links here and here, so a couple questions:
- what's the basic difference from a layman's (e.g., a manager's) perspective ?
- What training options are available for a generic 11g DBA to learn this new technology ? I've seen this course from an Oracle partner ("Course:Oracle 11g: RAC and Grid Infrastructure Administration Accelerated Release 2"), for a boat load of money, for 5 days I think. So we're looking for something a little more reasonable (and accessible), e.g., books, online, etc.

For a very basic definition, RAC is technology that is used by the database and GI is the infrastructure that makes RAC work. In a forum reply, that's probably all what can be said about both. For a very lengthy answer, you should read the links that you have quoted.
For #2, the course that you are looking at is called Accelerated as it combines two courses in a single week training-RAC(4) and GI(3). So it's a 7 day curriculum that one would be doing in a 5 day course and that should justify its cost. But let me say, it's a really really good course. But on the other side, it can be quite overwhelming for someone who doesn't know about these technologies already. So I shall suggest that you send your team to each course individually and probably after doing some homework . They can start reading the following books,
Pro Oracle Database 11g RAC on Linux
https://www.mheducation.co.in/html/9781259004063.html
And this doc link,
Oracle Database Online Documentation 11g Release 2 (11.2)

Oracle RAC and crossover cable for private network

Hi,
I have the following configuration: two database servers, each has four network cards, two for public network and two for private, cluster network. Each public card has own IP-address and both have virtual IP-address, defined in operation system (SLES-9) for redundancy. Because I have only two machines in the cluster I want to connect the two machines for private with crossover cable without switch. For redundancy I want to make two connections between machines. Is it at all possible? How should I defined all network interfaces and what should be included in /etc/hosts for properly work of Oracle cluster?
Best Regards,
Jacek

Hi,
You can build a RAC witch CROSSOVER, but the Oracle no homolog.
As you have 4 cards, 2 to public (redundancy) and 2 to interconnect (redundancy) you need of a software to to make a TEAM, and create a card virtual that will have a IP address.

RAC and Grid Computing

Hi,
I am trying to understand the connection between RAC and Grid Computing.
In RAC, we can have multiple instance of the same physical database and if all these instances are running on n* separate machines then we have n+ set of processes to take care of computation.
Isn't this summarise the Grid computing as well or is it something entirely different. Please share.
Thanks in Advance

Hi,
Billy already answered well.
Litte Note:
Timeline of Oracle Databases:
1992: Oracle version 7 appeared with support for referential integrity, stored procedures and triggers.
1997: Oracle Corporation released version 8, which supported object-oriented development and multimedia applications.
1999: The release of Oracle8i aimed to provide a database inter-operating better with the Internet (the i in the name stands for "Internet"). The Oracle8i database incorporated a native Java virtual machine (Oracle JVM, aka "Aurora").
2001: Oracle9i went into release with 400 new features, including the ability to read and write XML documents. 9i also provided an option for Oracle RAC, or "Real Application Clusters", a computer-cluster database, as a replacement for the Oracle Parallel Server (OPS) option.
2003: Oracle Corporation released Oracle Database 10g, which supported regular expressions. (The g stands for "grid"; emphasizing a marketing thrust of presenting 10g as "grid computing ready".)
2005: Oracle Database 10.2.0.1—aka Oracle Database 10g Release 2 (10gR2)—appeared.
2007: Oracle Corporation released Oracle Database 11g for Linux and for Microsoft Windows.
Future (*Just a guess*): Oracle Database will release version 12c. (The c stands for "cloud"; emphasizing a marketing thrust of presenting 12c as "Cloud Computing ready".)
Oracle has released products with "C" of the "Cloud" (e.g Oracle Enterprise Manager 12c)

New implementation - Client having issues with RAC and Grid on Windows

Client is starting a new implmenetation on Windows 2008 R1, Oracle 11.1.0.7. They have a 3 node RAC and Grid Control. They are having a number of issues and support is working through those issues. They are asking if there are clients on RAC and Grid on Windows. The Wiki shows a few customers on Windows, but was hoping to get some feedback. Tks.

There are lots of customer applications that are based on Windows RAC. And as mentioned above, it is very well supported by Oracle.
However, because of the security vulnerabilities of Windows, I've observed that most of the financial institutions and listed companies opt for unix based servers for all high profile applications and run only low to medium risk application on Windows.
Regarding maintanence issues, I guess it's going to be pretty much the same; there shall always be lots of bugs, lots of patches and updates just like an yother software; doesn't really matter if you are on Unix or Windows systems. As long as you purchase support, it's all good.
It's pretty much same concern regarding Grid Control on windows.
Cheers.

"Java and BAPI Technology for SAP" by by Ken Kroes - Is this book useful?

Howdy partners,
I've got a 'book' called "Java and BAPI Technology for SAP" by by Ken Kroes, Anil Thakur, Gareth M. deBruyn, Robert Lyfareff.
Now, does anyone know if the info in this book is still relevant to the modern SAP world? I mean its still talking about ITS and stuff like that?
Any input will be appreciated.

With the blue cover? I have one with the something similar title, but it's quite out of date. There was lot of improvement on the Java side.
So I would prefer something newer from SAP-PRESS. Check the SAP-PRESS site.
BTW I don't consider ITS as an old technology...it was just integrated recently into WAS 640 to make it more powerful. This is the only available technology, which converts classic Dynpro to Webpage dynamically.

Which is the difference between Oracle RAC and Oracle Clusterware?

Hi all, maybe this is a stupid question, but I've read the documentation, and still don't understand which is the difference between RAC and Clusterware.
Can anybody explain it to me?
Thanks in advance!

RAC is database option part of Oracle Database software needed to have database running in cluster mode; see http://download.oracle.com/docs/cd/E11882_01/server.112/e16508/glossary.htm#CNCPT2076.
Clusterware is separate software needed to run Oracle Database in cluster mode: you can use Oracle Clusterware without Oracle Database but you cannot use Oracle Database with RAC option without Oracle Clusterware.
See http://download.oracle.com/docs/cd/E11882_01/rac.112/e16794/intro.htm#BABCHEEE.

Oracle rac and TDE?

We are running oracle rac on 10.2.0.3 linux Itanium platform. I am setting up TDE for the first time and I setup my wallet location to be on an ocfs file system so that each node in the cluster will have access to the key. Is that all we will need to do and is this a supported configuration for TDE in a rac environment?
Do you have to open the wallet on each instance during instance startup when running rac?
Also we have a physicla standby server configured and I setup the same wallet location on the physicla standby and copied the wallet file over, Is that all we need to do for the standby server?
Thanks.

Peter,
Good info and your video makes everything look easy.
In addition to the encrypted wallet file (ewallet.p12), I also have a cwallet.sso file in the local file system (not ACFS) on both RAC nodes of my Primary and both Standby nodes.
If I start the database and then run: SELECT * FROM V$ENCRYPTION_WALLET; it says the wallet status is open. However, as soon as a user tries to connect through our application (using jdbc), I get the "ORA-28365: wallet is not open" errors in the alert log. So then I have to run: ALTER SYSTEM SET ENCRYPTION WALLET OPEN IDENTIFIED BY "<Wallet Password>"; on each node and then users can connect through the application.
Any ideas why auto-login doesn't work and why everything is grayed out on the Wallet Tab drop down menu in OWM?
Thanks.

Database replication between Oracle RAC and Oracle Standalone DB

Hi,
We have currently 4 node RAC environment and Oracle RAC implementation with 4 Oracle instances. We want to move the one instance and make it Standalone with Oracle database due to availability issue. Thus we will remain with 3 nodes on the RAC database and one Standalone database. We want to implement Oracle replication on this solution, where partial database of RAC environment needs to be replicated to Standalone node.
We will have Oracle 9i database server for both RAC and Standalone machine.
The partial data that we are looking for replication are of size 25GB. Some of questions we have:
1. Is there any other replication mechanism apart from Materilzed view for this solution?
2. Is it feasible to sychronize around 25GB data between servers?
3. What can be estimated time for refresh or Synchronization?
Thanks in advance for help.

The methods that we are evaluating currently for this replication are:
1. Multi Master replication
2. Oracle 9i Datagaurd.
Please let me know if we need to look for some other methods of replication also.

2. Is it feasible to sychronize around 25GB data between servers?Sure. Depending on the rate of change, your latency requirements, whether the standalone database has the horsepower to apply all the changes generated by to other three nodes, etc.
3. What can be estimated time for refresh or Synchronization?Depends on the architecture, the network connection, whether you are doing incremental refreshes, etc. And it depends on what time you're measuring-- you might be measuring the latency between the RAC cluster and the standalone database, you might be measuring the time it takes to incrementally refresh a single materailized view when there have been no changes, you might be measuring the time it takes to do a complete refresh of an entire refresh group, pulling 25 GB of data over the network.
The methods that we are evaluating currently for this replication are:
1. Multi Master replication
2. Oracle 9i Datagaurd.DataGuard is not an option if you only want to replicate a subset of the data. The two realistic options are materialized views and Streams. Are you anticipating that you will be making changes on both nodes? If not, you can use simple materialized views rather than multi-master replication.
Since 9.2 is not longer covered by Premier Support, are you planning to upgrade to a supported version in the near future? In particular, Streams works a lot better in later versions of the database.

Install SAP cluster ORACLE RAC and SCS

I need to install SAP ECC SR3 in an environment in cluster.
O.S: Linux Red Hat B.D: Oracle 10.2.0.4
I am trying to follow the official manual of SAP, but this very confused, would like the you aid.
The environment is the following one:
2 machine (Node A and Node B)
1 area of storage shared for datafiles of Oracle. /oracle/PRD.
It goes also to be installed ORACLE RAC.
My doubt is the following one: Which the steps that I have that to follow so that everything of certain.
When I go to install ORACLE RAC? Before, later or during the installation of SAP?
I go to need to install the central office services (SCS) in the two servers? Or only in one?
Somebody could help with some document or detail me of what I go to need to make?
Please!
Thanks!

Hi Alan,
Please go through this link [http://www.oracle.com/newsletters/sap/docs/wp-o10g-rac-config-unx.pdf] Hope this should help you.

SC 3.1/3.2 Oracle RAC and EMC replication

hi,
i need to cluster existing 2 node Oracle RAC for disaster recovery. The secondary site is about 180 km away, there is another site 10 km away which is planned to be use for bunker replication (SRDF/STAR). Is it possible to build such topology with Sun Cluster 3.1/3.2? Network connection to all sites is provided (min. 10Gbp).
What is needed to complete this task with SC?

I would recommend that you read my Blueprint from April 2006 (Architecting Availability and Disaster Recovery Solutions) as this has a lot of background on the subject.
First, you will need to implement it as a two node cluster plus a single node disaster recovery system. Ideally, the two node cluster would be configured between the two 'local' sites, i.e. with the site that is 10Km away. The remote site, at 180Km, would then be used for the disaster recovery system.
The recently announced Sun Cluster 3.2 Geographic Edition adds support for SRDF, so you could use Sun Cluster 3.2 and Geo Edition with SRDF for this. I would add that disk block based replication is not ideal for this as it does involve a lot of unnecessary replication data traffic compared with something like Oracle Data Guard. This would be my preferred option, although this is not currently integrated with Geo Edition.
If you need any more info or help, please post again.
