OS level Cluster and Oracle Database...

Is there a way to install one oracle database, on two servers that are set up in a Cluster on Operating System level so it can see it as one machine, that is: I want to use the capabilities of two servers, but to have Oracle Database see it as one server with two processors, drives etc.? Thanks,

A pure OS cluster can only act as a failover cluster, but it cannot emulate RAC functionality.
The database (single instance) runs on one node, in case of node down, it can be switched to the other node.

Using Coherence and Oracle Database as the CacheStore

We are working on implementing a solution using Coherence and Oracle Database as the CacheStore. We initially implemented the Cache as a distributed-scheme which in turn uses the backing-map-scheme. We are trying to introduce transaction management and I used a scheme-ref in a transactional-scheme to point to an already existing distributed-scheme. However when I bring up the server, my custom coherence-cache-config.xml file is not recognized and Coherence comes up with the default setting. Given below is the snippet of my configuration file.
1)     I would like to understand why the below configuration doesn’t work and am I doing it the right way? If not, what is the correct way of doing it?
2)     There are a multiple transaction management options given in the documentation. Which are the ones that will work with a distributed-scheme and read-write-backing-map-scheme?
3)     If transactional-schemes cannot work with distributed-scheme, what is the best way to have a distributed cache with a oracle database as a cache store?

</init-params>
</class-scheme>
</cachestore-scheme>

</read-write-backing-map-scheme>
</backing-map-scheme>
<autostart>true</autostart>
</distributed-scheme>

Hi,
If you look at the documentation for transactional-scheme here: http://docs.oracle.com/cd/E24290_01/coh.371/e22837/appendix_cacheconfig.htm#BHCIABHA
you will see that it says The transactional-scheme element defines a transactional cache, which is a specialized distributed cache. That means that a transactional-scheme is already a distributed-scheme.
You will see from the same documentation above that there is no way in a transactional-scheme to configure things like cache-stores or listeners or even the backing-map-scheme as these are not supported on a transactional-scheme - so you cannot use a cache store.
Personally I would not use transactional-scheme unless you have some really big reason to do so - the restrictions far outweigh any perceived advantage of having a transaction. There are better ways to build applications so they do not require transactions, that is what we have been doing for years with Coherence so far, and there is no real reason to change that.

Help: Creating a cluster for Oracle Database

In school, we've been testing the grid infraestructure, ASM and oracle database
but now, for a research, we should be able to install, Grid+Asm and oracle database Using at least 3 computers
where should we start?
we want to install all of them since the begining, I mean, A network. Operating system on each computer, disk slices for the ASM, and the Oracle database.
thanks in advance!

1. Install OS
2. Set IPs on DNS
3. Prepare the disk storage for ASM
4. create users,groups and directory,
5. install package requirements (see documentations or MOS)
6. runclufy to verify if the systems are ready to be installed
7. install grid infra
8. create diskgroup in asm
9. install oracle software
10. create database
11. verify installation
and the last one is please read http://download.oracle.com/docs/cd/E11882_01/install.112/e17214/toc.htm for full details. post here if you encounter problems
Cheers

No they cannot send you a document that is available only to those with access to MOS.
That would violate the conditions of having such service contract credentials.
Asking someone to violate such privileges is a serious offense and could get that other person's organization banned from all support and all their support contracts cancelled.

Slow Problems with Oracle Forms 10g and Oracle Database 11g

Hi, I wonder if there is a compatibility problem between Version 10.1.2.0.2 32 Oracle Forms and Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production. This is because my application runs correctly on a version of Oracle Database 10g, and when we migrated the database to an Oracle Database 11g, slowness problems came out.
Thanks.

We have the same issue happening with our custom forms and with some of the standard forms in EBSO. So far we have found that the form invoking a view causes ridiculous slowness in opening the form (40 mins). Using a table access has shortened the open time significantly. At this time Oracle DBAs at OOD have no clear idea why it is happening.
we are on 11.1 database with 11.5 EBSO

32 Bit Installation or Oracle Linux and Oracle Database 10g

I have an old E-Machine that I wanted to put Oracle Linux and Oracle Database Express 11G on. I was just wanting to do some testing and development on the system. I'm pretty sure the machine is 32bit.
I just burned a copy of 32 bit Oracle Linux onto a CD. Is there a version of Oracle Database Express that will run on it?
It seems like there is only a 64 bit version of Oracle Express Database 11g. Is Oracle Database Express 10g installable on Oracle Linux 32 bit?
Let me know! Thanks in an advance.

One (or two) caveats with the 10g version, XE can not be patched and the 10.2.0.1 XEs were created before the current daylight savings time rules went into effect.
If you have access to My Oracle Support there is a method to get updated timezone files for the oracle binaries, you need at least version 4 of the DST files. I've got the MOS docIDs somewhere let us know if needed and I'll dig 'em up.

Database locking using JSP and Oracle database

Dear All
I am reading about how to do database locking in general and i want to implement these mechanisms using JSP pages and oracle database, but i have the following questions:-
1.If i write a “select for update” quesry in the JSP page will it locks the record ? or it will not lock the record because the connection between the JSP pages and the server will be stateless in most online systems?
2.If i write all my jave code in transaction , something like this:-
• Begin transaction
• Commit or
• Rollback
Then should i be worried about the locking issues or the database manger will handle the locking mechanisms to insure data integrity(and what the default mechanism (if any) that the oracle database manger use to do the locking)?
3. If the answer for question 2 is no, then how can i handle the optimistic and the pentemistic locking using JSP pages?
BR

One way to solve this issue is as follows:
* You add a new column to each database table called 'version' which is of int type.
* Each time you alter any field in a record, you increament the version number.
* When you read a record and display it, you store the version number in your code
* when you go to update the record, you write your sql something like this:
update person set firstName=? where personId=? and version=?
Where the version is whatever you stored locally. If someone altered the record in the database while your
end user was looking at it, the version numbers will not match and the sql statement will
return zero as the number of records it altered. If its zero, inform the end user someone altered the record
while he was looking at it and weather or not he wants to proceed.
The chances of two people altering the same record in a table while both are logged in and viewing the same set of data is small so such collisions will be few.
You only need transactions if you are updating more than one record at a time (in the same table or multiple tables).
You dont need it for reading records if you use a single sql statement to read (for example: to join multiple tables).
In general, you get a (pooled) connection, use it, and close it as quickly as possible in a try/catch/finally block. You dont hold onto it for the duration of the user's session. A book on JDBC should help clarify this.

Sharing in Symetrics Array an Oracle datawerehouse and oracle database 9i

I
i want to know if someone have an sharing in Symetrics Array an Oracle
datawerehouse and oracle database 9i, or any array for high
availability. This because i have to do implement an installation
datawarehouse and db9i on the same arrary. Just know any comment if
whichever with share with me your expertise from any situation with
this, please.
Thanks

Thanks for the reply.
Actually I thought that the OCCI forum was for Object oriented OCI, so while I'm using C++, I'm not using the object oriented side of OCI, just using the normal OCI calls. Guess I should have been a little clearer in my original post.
But my main question really concerned the version of the client and the version of the database which you answered.
Thanks,
Nick

How should I try out Oracle Grid and Oracle database?

I want to try out Oracle Grid and Oracle database in a virtualized test environment. I have already downloaded the Oracle VM VirtualBox for Windows platform. The OS for the production environment is RHEL. So, do I just need to download Oracle Linux? How about the VM Manager, VM Server, and Oracle programs?

You can use the standard distribution media from http://www.oracle.com/technetwork/indexes/downloads/index.html and https://edelivery.oracle.com/linux to install Oracle Linux and Oracle 11g in Virtualbox. Virtualbox can use real disk media as well as .iso disk image files. Oracle Linux 6 is not certified for any Oracle database product yet. Your best option will be to install Oracle Linux 5.7 and then install the Oracle-Validated software package to prepare Oracle Linux for the Oracle database installation.
Virtualbox and Oracle VM are different products. Oracle VM, including OVM server and manager installs its own operating system and is designed for installations on bare metal machines. Virtualbox is an application that requires a primary host OS, e.g. Windows, MacOSX, Linux, to install one or more virtual machines with Windows or Linux guest systems.

CAN I INSTALL BOTH (ORACLE 9IAS AND ORACLE DATABASE )INTO SAME MACHINE.

oracle 9ias and oracle 9i database in same machine Feb 25, 2003 11:22 PM
Reply
Dear Friends,
I installed oracle 9ias. and then i hosted my form,report into that server . All was working properly.
at this time my database was into another machine.
then i installed oracle 9i database into the same machine
(as the oracle 9ias was installed)
at the instalation of oracle 9i database one error comes
and shows that Agent configuration Assistant Installation
fail.
but After installation of database it work properly.
there is no problem.
but when I try to run from through web(by using oracle 9ias)
it gives Internal error(500).
i check and find that my appache server for 9ias is working properly and in services of windows 2000 no error comes.
HOW CAN I INSTALL BOTH (ORACLE 9IAS AND ORACLE DATABASE )INTO SAME MACHINE.
With regards
