Oracle Clustre, Oracle Cluster with RAC and Oracle 10g

Is there a difference between Oracle Cluster and Oracle Cluster with RAC? Please explain. Do existing database codes run unmodified in Cluster or Cluster with RAC environment? What needs to be modified to make existing SQL codes RAC-aware. How to achieve 'all automatic' in case of failure and resubmission of Queries from failed instance to a running instance?
In 10g environment, do we need to consider licensing of RAC as a separate product? What are additional features one derives in 10g that is not in Cluster +RAC?
Your comments and pointers to comparison study and pictorial clarification will be very helpful.

Oracle cluster like failsafe before or Veritas Cluster or other vendor's cluster is meant for HA (high availability) purpose. Which 2 nodes or more can see a shared disk with 1 active node. Whenever this active node failed through heartbeat other machine will know and will take the database over from there.
Oracle RAC is more for HA and load balance. In Oracle RAC 2 or more nodes are accessing the database at the same time so it spread load across all these nodes.
I believe Oracle 10g RAC still need seperate license for it. But you need to call Oracle or check the production document to verify it.
Oracle 10g besides improvement in RAC. It's main improvement is on the build in management of the database itself. It can monitored and selftune itself to much furthur level then before and give DBA much more information to determine the cause of the problem as well. Plus improvement on lots of utility as well like RMAN , data pump etc... I don't want to get into too much detail on this you can check on their 10g new features for more detail view.
Hope this help. :)

Parameters of NFS in Solaris 10 and Oracle Linux 6 with ZFS Storage 7420 in cluster without database

Hello,
I have ZFS 7420 in cluster and OS Solaris 10 and Oracle Linux 6 without DB and I need mount share NFS in this OS and I do not know which parameters are the best for this.
Wich are the best parameters to mount share NFS in Solaris 10 or Oracle Linux 6?
Thanks
Best regards.

Hi Pascal,
My question is because when We mount share NFS in some servers for example Exadata Database Machine or Super Cluster for best performance we need mount this shares with specific parameters, for example.
Exadata
192.168.36.200:/export/dbname/backup1 /zfssa/dbname/backup1 nfs rw,bg,hard,nointr,rsize=131072,wsize=1048576,tcp,nfsvers=3,timeo=600 0 0
Super Cluster
sscsn1-stor:/export/ssc-shares/share1 - /export/share1 nfs - yes rw,bg,hard,nointr,rsize=131072,wsize=131072,proto=tcp,vers=3
Now,
My network is 10GBE
What happen with normal servers only with OS (Solaris and Linux)?
Which parameters I need use for best performance?
or are not necessary specific parameters.
Thanks.
Best regards.

Select query differences between oracle 9 and oracle 8.

Hi,
I have a problem using the select query between oracle 7 and oracle 9i I don't have the same result :
ex:
With oracle7
SQL> select 'champ1','champ2' from DUAL;
'CHAMP 'CHAMP
champ1 champ2
With Oracle 9
SQL> select 'champ1','champ2' from DUAL;
'CHAMP1' 'CHAMP2'
champ1 champ2
So Can someone tell me how to solve this problem ? Is there a parameter in oracle 9 to set?
Thanx.

Whenever you are posting anything over internet forums like this - you should be very careful about not just posting the details which requires to solve the problem - also should be sensible about your question.
This is not at all desired when you are posting such question. It may be because - you may not well aware of the fact.
My suggestion is -> First Go through the basics Of SQL in general.
Then go for any specific product like Oracle/ SQL Server/ Sybase etc.
And, finally learn the advanced commands of that DB.
You asked it - may be you thought the difference in output in terms of lines. But, that is not your actual output. That is the graphical display part only.
Anyway,
You can get the quite familier output by first type the following command ->
set lin 310Regards.

Differences between Oracle 8i for a UNIX Platform and Oracle 8i for a Linux Platform

Hello,
J would like to know if there are some differences between Oracle 8i for a UNIX Platform and Oracle 8i for a Linux Platform.
I know that there are some differences on Oracle 8i Parallel Server and i know that some products are not include like precompiler (Mod*Ada, Pro*FORTRAN) on a Linux Platform.
Thank you.

We have installed Oracle 8i on Solaris 8 and it had a great performance, of course that the hardware and licence invested here was costed my the office where i work. Personaly i'd installed linux reh hat 8 and oracle 8i, imagine that, it could be implemented by any individual that has the time to do so.
By buyinng from a company that has a good background you could be sure that you will have support.
Bottom line, if you have the $ to buy great hardware go for a unix platform. But if you don't a Red Hat Linux Server Licence with a 1 year sopport and Oracle data base is about 3500Dls.

Differences between Oracle BAM and Oracle BI and Question BAM Data Objects

Hi,
I have two questions.
1. Can someone tell me differences between Oracle BAM and Oracle BI?
My understanding about Oracle BAM is, we use BAM to build Dashboards or Reports.
We can also build DashBoards or reports using Oracle BI.
I am not able to understand why Oracle has two tools for same purpose?
Which tool is more powerful and user friendly(Oracle BI or Oracle BAM)?
2. Every time we plan to develop Dashboard or report in BAM, we need to create BAM ADC Data Object to store Data (i.e first step is to get data from external database or application and second step is to store data in BAM ADC data object).
My understanding is we have an extra step(i.e creating Data Object) in Oracle BAM to develop a report or DashBoard
I am wrong pl correct me?

Shanti Nagulapalli.

Architectural Difference between Oracle 8i and Oracle 9i

hello there
anybody can tell me precisely what is the architecture difference in Oracle 8i and Oracle 9i.
or provide me the link where i can get it.
waiting for reply

What do you mean by "architectural differences"? Fundamentally, Oracle architecture hasn't changed a whole lot in a couple of decades. Certain implementations within the overall Oracle architecture will change over time, normally to support some new feature.
Locally managed tablespaces, for example, automatic segment space management, and automatic extent allocation are pretty important new features, but they don't fundamentally change the architecture of allocating space for objects to store data.

What is Difference between ANSI SQL and ORACLE SQL

Hi,
I am going to take the assesment test for ANSI SQL Programming before that i want to know any difference between ANSI SQL and ORACLE SQL?
I am studying for SQL but the test will be ANSI SQL please let me give an idea about the both.
Thanks
Merina Roslin

Basically there is syntax difference between both of them.
Lets say i want to join two table EMP and DEPT based on DEPTNO.
With Oracle SQL format its like this.
select e.*
from emp e, dept d
where e.deptno = d.deptnoHere the joining condition goes in the WHERE clause.
With ANSI SQL format its like this.
select e.*
from emp e
join dept d
on e.deptno = d.deptnoHere the join condition is mentioned separately and not in WHERE clause.
Oracle supports ANSI SQL starting from 9i version.
You can read more about the syntax difference Here
