Clustering in Oracle 11g/10g

Hi
We have 40000 records in our database (Oracle 11g/10g), in which each record holds 2 to 3 images and so each record will be of some MBs.
Do we need to perform clustering to get a better performance?
Thanks
Shoba Anandhan

Thanks for the immediate replies.
We have a Windows 2003 Server, where in we have the Microsoft Visual Studio 2008 and Oracle 11g database.
Our web application will be developed using Microsoft Visual Studio 2008 having Oracle as backend.
At at time we are assuming 100 users to work with the web applications. We connect to the database everytime to display data in the web page.
100% performance is expected.
The Windows 2003 Server has a 4 GB of RAM. Is 4 GB enough to process these database requests or do we need more?

Oracle 11G,10g and DB2 replication?

Oracle 11G,10g and DB2 replication?
=======================================
We are using Oracle 11gR2. We have a table in Oracle filled with partial data (over 200K+, it may grow to 1M). The rest need to be obtained from DB2. It is not from one DB2 table.
The DB2 is configured to run Oracle 10g within it. We have given http interface, where we need to supply(Push) the partial data using HTTP_UTIL package for each row, then DB2/Oracle 10g return the result as XML.
It is a network heavy, slow and not reliable.
Are we able to replicate tables between Oracle 11g and DB2/oracle 10g?
We like to leverage the features on 11gR2 effectively.
I find some interesting folks in this forum.
Did anyone face such situation?
I like to know the best approach with good performance options.
Any idea?
Thanks in helping.

why is DB2 required to produce XML?

hi,
I have installed VM WARE on my laptop now want to download linux ISO and Oracle ISO. Red Hat, Centos and Oracle Enterprise Linux are almost identical. The major differences are:
- Red Hat and Oracle Enterprise Linux are officially supported by Oracle to be used under Oracle products;
- CentOS is NOT officially supported
- the newer Oracle Enterprise Linux (OEL) includes an 'oracle-validate' rpm to reduce configuration guessing
Each Distro has it's purpose. I use SUSE and OpenSUSE for my office. And for general servers I use RedHat (when I need commercial support) and CentOS. I fully support CentOS and the CentOS community effort.
However, for the past year I have ONLY used Oracle Enteprise Linux under Oracle product. It is free, it is officially supported, if I need commercial support I can get it, and it has the Oracle Validated RPM to minimize my config effort. http://edelivery.oracle.com
So, as compared to the other respondent - I encourage using OEL and NOT CentOS.

Problem migrating ear from Oracle AS 10g to 11g.

Hi
I need to deploy an ear file in Oracle AS 11g. The ear has war in it.
The ear file has uix pages and the supporting files (EOs and VOs).
Using Oracle AS 10g:
Here, i used to create a OC4J container and deploy the ear in this container.
Using Oracle AS 11g:
As there is no OC4J container support here, I have to deploy the ear in the
weblogic server. I am facing problems doing so.
In weblogic console,
1) I have created a server and got it running.
2) Went to 'Deployments' page and clicked on 'Install'.
3) Entered the path for the ear file and pressed 'Next'
I am getting the following error:
X - Error Unable to access the selected application.
X - Message icon - Error Exception in AppMerge flows' progression
X - Message icon - Error Exception in AppMerge flows' progression

X - Message icon - Error Bean already exists: "weblogic.j2ee.descriptor.ParamValueBeanImpl@bdc14d68(/[uix]/InitParams[oracle.cabo.ui.UIExtensions])"
Can someone tell me if how this can be done or point me to an appropriate tutorial.
It will be of great help.

Difference in select for update of - in Oracle Database 10g and 11g

Hi, I found out that Oracle Database 10g and 11g treat the following PL/SQL block differently (I am using scott schema for convenience):
DECLARE
  v_ename bonus.ename%TYPE;
BEGIN
  SELECT b.ename
    INTO v_ename
    FROM bonus b
    JOIN emp e ON b.ename = e.ename
    JOIN dept d ON d.deptno = e.deptno
   WHERE b.ename = 'Scott'
     FOR UPDATE OF b.ename;
END;
/While in 10g (10.2) this code ends successfully (well NO_DATA_FOUND exception is raised but that is expected), in 11g (11.2) it raises exception "column ambiguously defined". And that is definitely not expected. It seems like it does not take into account table alias because I found out that when I change the column in FOR UPDATE OF e.empno (also does not work) to e.mgr (which is unique) it starts working. So is this some error in 11g? Any thoughts?

It seems that my question was answered here - http://stackoverflow.com/questions/2736426/difference-in-select-for-update-of-in-oracle-database-10g-and-11g

The behaviour seems like it really is a bug and can be avoided using non-ANSI syntax. (It makes me wonder why Oracle maintains two query languages while dumb me thinks that this is just a preprocessor matter and query engine could be the same).

Issues expected in oracle 9i/10g to 11g upgrade

Hi.
We are planning to migrate some 95 odd applications from Oracle 9i/10g to 11g. The upgrade method we are planning to use is to setup 11g target servers and move databases from source to target using import/export. Then do the necessary changes in the app code and connect the application to the new target server and test.
The source OS may be RHEL 3/4/5 or Solaris 8 and target OS will be RHEL 4/5 or Solaris 10.
My questions are:
1. What can be the expected database side issues possible while moving the structure+data+views/sps etc from old version to new version using import/export.
2. How much time may it take to move the database from source to target for say a 100GB database?
3. Will the change of OS have any implications on the movement from source to target?
4. What are the application side issues possible considering that most apps use odbc/jdbc to connect to the datastores?
5. Can any application side inline queries be affected?
6. Will there be any changes to the column data types from 9i/10g to 11g which can impact the code?
Thanks,

1. What can be the expected database side issues possible while moving the structure+data+views/sps etc from old version to new version using import/export. If you complete the steps in (Interoperability Notes Oracle EBS 11i with Oracle Database 11gR2 (11.2.0.2) [ID 881505.1]) please see these docs.

2. How much time may it take to move the database from source to target for say a 100GB database? Depends on many factors -- Try this on a test instance with similar hardware configuration and setup to production to estimate the time.
3. Will the change of OS have any implications on the movement from source to target?No, but you may relink the executable files -- How to Relink Oracle Database Software on UNIX [ID 131321.1]
4. What are the application side issues possible considering that most apps use odbc/jdbc to connect to the datastores? If you run AutoConfig with no errors when there should be no issues with ODBC/JDBC connectivity.
5. Can any application side inline queries be affected? It should not be affected expect if you custom code use some features which are no longer available in 11g database.
6. Will there be any changes to the column data types from 9i/10g to 11g which can impact the code?Typically no, however you need to do full and proper testing to verify.

Need help regarding upgrading Oracle 10g Forms to Oracle 11g Fusion Middlew

Hi All,
I am trying to create a workshop on a VM for showing the migration / upgrading of Oracle Forms 10g to Oracle 11g FMW using the Upgrade Assistant tool available in <ORACLE_HOME>/bin/ua.bat.
As per my understanding of pre-requisites:
1)     I need to install Oracle SOA Suite 10g on my VM.
2)     I also need to install Oracle SOA Suite 11g on my VM.
3)     I need to install Oracle Forms/Reports Services 10g on my Oracle SOA Suite 10g installation.
4)     I need to run Oracle Forms/reports installer on my Oracle SOA Suite 11g installation.
5)     I need to run upgrade assistant tool on my VM to upgrade my form from source(Oracle SOA Suite 10g) to destination(Oracle SOA Suite 11g). Is it mandatory for this migration that I should have Oracle SOA Suite 10g and Oracle SOA Suite 11g on the same system ?
Having all these software installed on one VM would be difficult. So just wanted to check can I avoid any software to install on VM ?
If there is any alternative suggestion then please let me know.
Regards,

What do you want to do with the SOA-suite? At least for Froms10G is is not necessary.

Hi all,
I would like to know what the differences between Oracle and other NoSQL database are.
When and why should we use Oracle?I suggest that you start here:
http://www.oracle.com/technetwork/database/nosqldb/overview/index.html
Is Oracle NoSQL database link with Big Data Appliance?Yes, Oracle NoSQL Database will be a component of the Big Data Appliance.
Can we use map-reduce on a single personal computer? How should we install Oracle NoSQL database to use map reduce on a single personal computer?Yes, I believe you can run M/R on a single computer. Consult the various pieces of documentation available on the web. You may run Oracle NoSQL Database on the same computer that you are running M/R on, but it is likely that they will compete for CPU and IO resources and therefore performance may suffer.
Do we also have eventual consistency with Oracle NoSQL database? Yes.
Can we lose data if master node fails?If you run Oracle NoSQL Database with the default (recommended) durability settings, then if the master fails, a new one will be elected and data is not lost.
Are transactions ACID with Oracle NoSQL database? How can we prove it?Yes, each operation is executed in an ACID transaction. The API has the concept of "multi" operations which allow the caller to perform multiple operations on sets of records with the same major key, but different minor keys. Those operations are also performed within a transaction.

Differences between Oracle Discoverer 10g and 11g (EBS & Desktop)

We are in the process of upgrading from Oracle Discoverer 10g testing to Oracle Discoverer 11g.
We have had several requests (from functional users) for documentation that might reflect the changes in this release level. Does anyone have relevant documentation that might help explain what has changed so that they can be better prepared.

We are in the process of going from 10 desktop to 11 plus. I do not like it as other end-users I have talked to don't either. In desktop, I could have multiple reports open at one time, move tabs from one report to another so I wouldn't have to rebuild the report again. Also, there are times I have 3 or more sessions of desktop running with multiple reports running in them. In plus, I am limited to one session and one report. That slows down productivity big time. In desktop, exporting crosstabs to excel is more user friendly than plus. For desktop, it will fill in the cells below with the data above it if it changes. In plus, it looks like a pivot table. I have read other posts on how to work around that, but not always functional. Using Dense_Rank() works sometimes depending on how the report is written. IT is researching another way but haven't heard back from the consultants. Or, I will have to modify all my excel files with formulas to do that for me. Also in desktop, I can select all and copy paste the results into excel and all data comes in. The row and column headers, page items and even the title section will paste into excel. Plus only gives you the data, no row or column headers. So I have to export it every time I need the data. I have formatted excel files that all I need to do is copy paste and data flows beautifully. As for organizing and saving reports, desktop is much better. I can save reports out on our network under different folders so I can find them faster by topic. Granted, if that directory is an open one, anyone can change/delete it. In plus, the only advantage of saving it on the database is I can sort and search for reports or users. If you make any changes in plus and then walk away from your desk, plus will shut down after a certain time period. If you didn't save it, you have to start over. Don't know if this is something IT can fix???
As we see it, plus is a step back in technology. I hope someone can change that opinion. Don't know if we are not getting the best support from whoever is working with us (Oracle or 3rd party) or we are missing something???? If so, please share.
Thanks.

Oracle 11g- Straing behaviour of query after importing from Oracle 10g

Hi,
I have a table in Oracle 10g as follows:
Create Table xyz (col1 varchar2(50), col2 varchar2(50));
With following Data
Col1     Col2
A     320
A     110
A     290
A     380
B     ABC
B     256
B     LMN
I am running following Query
select * from xyz
Where Col1='A' and Col2=110
It works fine. But when I export this table and import it in Oracle 11g. It says invlid identifier.
But if I enclose 110 in single quotes. It works fine.
Also If I recreate this table in Oracle 11g like
Create table xyz1
as select * from xyz;
Now alos I am able to run this query smoothly.
select * from xyz1
Where Col1='A' and Col2=110
What is wrong exporting this table from 10g to 11g.
Any comments/suggestion??
Aarbi

The check in your where clause
Col2=110Is comparing a string (Col2 is defined as a VARCHAR) with a numeric literal, so there will be an implicit conversion taking place from character to number. The query then fails due to the B LMN row when 'LMN' fails number conversion.
I'm guessing there was there an index on the table in your 10g installation which would allow the query to be satisfied without checking the B ABC or B LMN rows but is not present or not used in the 11g installation so a full table scan results in an attempt to convert 'ABC' and 'LMN' to a number. Check the explain plans.
Or it could even just be a difference in the order in which the two conditions in the where clause are evaulated between the two versions.
The solution, as you have already found is to do a string comparision
Col2='110'Edited by: Cyn on Dec 7, 2009 12:38 PM

Oracle 10g vs Oracle 11g query performance

Hi everyone,
We are moving from Oracle 10g to Oracle 11g database.
I have a query which in Oracle 1g takes 85 seconds to run, but when I run the same query in Oracle 11g database, it takes 635 seconds.
I have confirmed that all indexes on tables involved are enabled.
Does anyone have any pointers, what should I look into. I have compared explain plans and clearly they are different. Oracle 11g is taking a different approach than Oracle 1g.
Thanks

Pl post details of OS versions, exact database versions (to 4 digits) and init.ora parameters of the 10g and 11g databases. Have statistics been gathered after the upgrade ?
