Is there a way to estimate storage savings for Hybrid Columnar Compression

Hi Experts
Is there a way to estimate the storage savings for Hybrid Columnar Compression (HCC) in Oracle Exadata x3-2 machine ? ?
Urgent Please...
Cheers
Kumar

That is correct. Basically, the newest partitions (most likely to be queried) were given the least compression (none) whereas the oldest partitions (unlikely* to be queried as the table contains 7 years' of data) were given the most compression (archive high).
As long as you keep your global stats up to date, it really seems transparent to the end user. I have not listened to a single complaint since this table was HCC'd :)
In all seriousness, end users haven't commented. I wouldn't be surprised to hear that some queries might run faster with HCC, some did in testing. It certainly hasn't caused any problems - it's a rarity: a new technology that worked exactly as it promised on its first try!
It is definitely worth implementing - just make sure the 'range' of data you use for a compression unit is large enough for you to see significant compression.
* without becoming a victim of DBARage: "exactly WHY do you need to get 7 years of data - and HOW are you going to use 4.5Tb of information, precisely? Someone might find they're not able to login to the EDW for more than 2 minutes at one time tomorrow...,etc "

What are the solutions offered by Oracle to handle length based products

We are on 11.5.10. Current version treats beams as each, we have 30 feet beams, 20 feet beams etc.
We do not want to set-up different items for each length of beam.
We need ability to tell we have 10 pieces of 26 feet beams in inventory.
Currently we can only tell we have 260 feet of beams.
Current solution treats it discretley. We need ability to sell length based items, receive length based items, do inventory management based on length based items.
a) What are the solutions offered by Oracle in latest releases for Length based products or for Mill products.
b) If there are any solutions offered by Oracle to handle length based or mill products, can these be back ported to Oracle 11.5.10?

Please do not create duplicate posts across the forums -- What are the solutions offered to handle length based or mill products?

Hi,
Just check below link..would be helpful..
http://www.oracle.com/global/ap/openworld/ppt_download/database_manageability%2011g%20overview_230.pdf
and
Each release of Oracle has many differences, and Oracle 10g is a major re-write of the Oracle kernel from Oracle 9i. While there are several hundred new features and other differences between 9i and 10g, here are the major differences between Oracle9i and Oracle10g:
Major changes to SQL optimizer internals
Oracle Grid computing
AWR and ASH tables incorporated into Oracle Performance Pack and Diagnostic Pack options
Automated Session History (ASH) materializes the Oracle Wait Interface over time
Data Pump replaces imp utility with impdp
Automatic Database Diagnostic Monitor (ADDM)
SQLTuning Advisor
SQLAccess Advisor
Rolling database upgrades (using Oracle10g RAC)
dbms_scheduler package replaces dbms_job for scheduling
and you need to refer oracle documentation for sql, plsql references where you will know particular enhancements made...
thanks

What are the advantage of using Oracle Database when compare to SQL SERVER

Hi,
There are various differences between the two.
1. SQL Server is only Windows, but Oracle runs on almost all Platforms.
2. You can have multiple databases in SQL Server, but Oracle provides you only one database per instance.Given that the very term 'database' has s different meaning in the two products, this "difference" is absolutely meaningless.
3. SQL Server provides T-SQL for writing programs, whereas Oracle provides PL/SQLWhich means what? Both products have a procedural programming language. They named them differently, and the languages are not interchangeable. Means nothing in comparing the features/strengths/weaknesses/suitability to purpose.
4. Backup types in both are the same. (Except Oracle provides an additional backup called Logical Backup.)You make that sound like "Logical Backup" is something more than it is. It is nothing more than an export of the data and metadata. Many experts don't even consider it a backup. I'm sure SQL Server provides the same functionality though they probably call it by some other name.
5. Both provide High Availability.Well, I guess they both have a suite of features they refer to as "High Availability". But what does that really mean? The devil is in the details. Remember, the two products don't even agree on what constitutes a "database".
6. Both come in various distributions.???

If you are going for an Implementation, you can try SQL Server Express Edition and Oracle XE which are free to use.
Then you can choose whichever is comfortable for your needs.
Thanks.

What is the best platform for Oracle Server?

What is the best platform for Oracle Server?
What is your criterion?
Thanks,
Somsak B.

I believe that Oracle is developed and coded on a Solaris
platform and then ported to other operating systems. If that is
the case, you can assume that Solaris is the best platform or at
least the safest in terms of performance and risk.
If anyone knows anything to the contrary, pls correct me.

What is the solution of non-oracle exception erro 100501

what is the solution of non-oracle exception erro 100501

I'm guessing that the TRUE parameter in My_Alert causes the procedure to raise a form_trigger_failure. In that case you could do this:
Declare
A number(10);
Begin
SELECT Sif_Code
INTO A
FROM Pro_Stp_Rcp_Item
WHERE Sif_Code = :Pro_Stp_Rcp_Item.Sif_Code
AND Rou_Code = :Routes.Rou_Code;
My_Alert('Item Code Already Registered',1,TRUE);
Exception
When form_trigger_failure then
    raise;
When No_Data_Found Then null;
When Too_Many_Rows
    Then My_Alert('Item Code Already Registered',1,TRUE);
When Others
    Then My_Alert(Sqlerrm||' - '||sqlcode,1,TRUE);
End;As Steve says, the problem is really caused by When Others here. I've got no problem with trapping "Others" but in forms you might be better off having a generic catch-all in the on-error trigger.

What are Built In's in Oracle forms. Are they like built in trigggers. how

What are Built In's in Oracle forms. Are they like built in trigggers. how r they different from triggers which r also bulit in.
thanks

a trigger is something, which runs, when an event fires.
a built-in is like a function or procedure, which helps you doing your work.
e.g.
go_block ('myBlock'); - navigates to the block
execute_query - starts a query
exit_form -ends the form
you can's compare triggers and built-ins. They are totally different.
In a trigger you can use built-ins to establish a functionality

What are the steps to apply Oracle Patch?

What are the steps to apply Oracle Patch?

Hi,
apply patch != apply patchset
Generally, patch is apply with opatch tool (from 9i), and there is an exe for patchset.
But, as it already said, the reading of readme is always a good idea...

What are the installation steps for Oracle Fusion HCM

Hi all
I will like to ask, what are the installation steps for Oracle Fusion HCM as well as can it work on Windows or only on virtual machine?
Thanks

If you're looking to install Fusion HCM, your best bet is to install on linux, eg, Oracle Enterprise Linux. It's up to you whether you put that in a Virtual Machine or not. I don't think Windows is an available platform for Fusion Apps at the moment, although am prepared to be corrected if you find anything to the contrary!
If you're looking to do an install on your own PC/laptop, you're probably out of luck - you'll be needing around 128GB of RAM. Check out this post:
http://onlineappsdba.com/index.php/2011/11/02/fusion-applications-128-gb-memory-and-500-gb-disk-space-are-you-ready/
Atul has also posted some good stuff on installing:

What is the communication technology for 3D Active shutter?

Hello,
I purchase Toshiba 3D screen 46tl438, the TV supplied with two active 3D glasses model: FPT-AG02G.
I look pretty much everywhere (including the manual and on the glasses themselves) what is the communication technology? IR, RF or BP?
I also try in Toshiba web but with no success.
Thanks in advanced,
Kobi

I think its IR because the module is placed in the middle of the glasses and the same info about IR can be found on other webpages.
