Advantage for use undo_management MANUAL oracle 9i DWH
Hi,
I have a questions,
What is the advantage for use undo_management MANUAL oracle 9i in DWH vs undo_management AUTO?
I need to obtain the UNDO_BLOCK_PER_SEC, but when I try to obtain the information in the view v$undostat, appear "no rows selected", exist any form to obtain this information?
Thanks for your help!!
Regards!!
To add to what SB said, do not tune what does not need tuning. That is, do not make changes till you have developed a case to support the change.
In order to learn how to work with rollback segments look in your DBA Administration manual. Since Oracle now puts the emphasis on automatic undo management I would look for an earlier version of the documentation set and reference it since there is probably more information in the manual where manual RBS management was the only method.
If you are a warehouse I would expect the number of users performing DML to be low and the update jobs to be large so I would expect a low number of large RBS segments to be allocated.

Configuration of XSQL for use with non-Oracle dbs
If anyone has positive experiences with configuring XSQL for use with non Oracle databases I'd like to hear how they did it, see tutorials, configuration files, etc.
Specifically setting up to use MySQL or Postgresql on Linux/FreeBSD would be very interesting.
Also, does anyone use this without setting mime types? How would you go about this so you could point to the relevant servlets in the page?
JoshI don't understand how setting up for Non-Oracle DB's is related to not setting up the servlet as an extension-mapped servlet.
It might work, but would you run JSP's
that way? XSQL behaves very similiarly
inside to how a JSP runner works, which
wants to be servlet-mapped.
However, OAS 4.0.8.1 does not support
extension mapping and XSQL works there
so i'm assuming it would work on other
servers set up that way. It's not
a configuration we test/certify.

Support for using TNSNAMES with Oracle Thin Driver?
Hi.
In the official Oracle JDBC FAQ (http://www.oracle.com/technology/tech/java/sqlj_jdbc/htdocs/jdbc_faq.htm), they say that from the "10.2.0.1.0" release, the Thin driver hast support for using TNSNAMES entries. Thus, you can use URLs like this:
jdbc:oracle:thin:@GL (thin driver, but connection info defined in tnsnames.ora)
Does anyone know how could I use an URL like this? Do I have to install the Oracle client? or can I simply copy a tnsnames.ora file someplace on disk and specify its ubication through an environment variable or something like that?
I haven't find util information in the Oracle site....any ideas are much appreciated.
Thanks in advance.I just found some info here:

Advantage of using RAW devices for storing database
Hi,
Marry Christmas to all.
Oracle 10g version 10.2.0.1.0 (rac)
OS : HP-UX 11i
I am new to this enviornment. We are using raw devices for storig the database.
Please tell what are the advantages for using raw devices for storing the database?
Thanks.http://www.fors.com/orasupp/unix/37914_1.HTM
The above link explains the raw devices and advantages. -
What are the advantages of using Map IDs?
Hi:
I am trying to find out the advantages for using map ids as
opposed to just using the file names for the topics, but I couldn't
find this information in the RH7 Help or the forums. Can you please
list the advantages and disadvantages.
Also, I am describing how I wish to implement the context
sensitive help feature for my application and you can tell me which
approach is better. We make an application that is packaged within
a Java IDE. We want to launch context sensitive help topics from
the wizards and cheat sheets. Now, this context sensitive help can
be either be installed on the local machine or network (file://
protocol) or available on our portal (https:// protocol). We do
have the infrastructure in place to let the user decide whether
he/she wants to access the local help topic or the one over the
internet. Will map ids work for both the scenarios?
Thanks,
KIt sounds like your application call needs to call an online
version of the help first and if this is not available to point to
a local copy. Is that right? If so, how this happens is entirely in
the hands of your developers. I know it can be done, just sketchy
on the actual procedure.
As far as the CSH in the help is concerned, you can use
mapids for both versions of the help if you want. If using webhelp
you'd do well to check out
this
link on Peter Grainge's site. -

Hello guyz... I never even tried to use oracle in my projects.. but I am curious what are the advantages of using Oracle compared with the other database....
plus the warm fuzzy feeling of creating employment for hungry Oracle DBAs :)
Just kidding. Oracle is a good database to know just because it's used so much.
So even if it weren't exceedingly powerful, stable, and versatile you'd still be doing yourself a disservice by not knowing at least something about it. -
Advantages of using Oracle with Unix over Windows server
Hi there,
I want some article/document which depicts the advantages of using Oracle with Unix (say HP-UX or Solaris backend). Actually the plan is to use some Data Warehousing applications using Cognos Poweplay, ReportNet and either Decision Stream of Cognos or Oracle Warehouse builder may be used as ETL tool. For Data mining applications we are planning to use SPSS Clementine. The Data volume will be substantial one. At present we are developing some prototype in Windows 2003 advanced environment. We are plaiing to use Risc server and RAID-5. Pl. advice some ideal architecture for us, as you know, it's typically a Govt. level application data (mostly archival data). The reports will be published using Report Net, Adhoc query etc, OLAP analysis will be done using Powerplay.

What are the advantage of using Oracle Database when compare to SQL SERVER
Hi all
Please tell anyone about
what are the advantage of using Oracle Database when compare to SQL SERVER

Balamurugan Suser12842738 wrote:
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,
MuraliDharan VHi MuraliDharan V,
It would had been better if you had searched first;
Here is one
Advantage for Linux64-bit Versus Solaris-x86_64 OS in RAC
And beside that your question is incomplete:
-What Oracle? Database, etc
-Which Version? 9i, 10g, etc
Aside from that a simple search on google might have answered your question as well.
But I think there is some new trend of dumping questions here before searching.

Notes on Transferring OverDrive MP3 Audiobooks…
Most MP3 capable devices should play OverDrive MP3 Audiobooks.
If you intend to transfer OverDrive MP3 Audiobooks to an Apple® device, note the following…
iTunes® v9.0.2 (or newer) is required.
The Apple device must be formatted for use with Microsoft® Windows®.
The iTunes setting 'Manually manage music…' must be enabled for the device before you can complete the transfer. Adjust this setting in iTunes as follows…
Connect the iPod® to your computer.
If it does not launch automatically, open iTunes v9.0.2 (or newer).
In iTunes, locate the device in the left vertical navigation panel (under heading 'DEVICES'), and click the device.
The 'Summary' screen is displayed.
Place a checkmark next to 'Manually manage music…'.
Click the 'Apply' button.
The iTunes 'Summary' screen refreshes, and the changes are saved.
If desired, close iTunes.
Note that if an Apple device is connected to your computer, you can choose to simultaneously transfer a title to the iTunes Library and the Apple device. If you wish to only transfer a title to the iTunes Library, you must first disconnect the Apple deviceRecovering your iTunes library from your iPod or iOS device: Apple Support Communities
Also you said " I want to add them to my iCloud, and also back to my computer. " Note that unless subscribe to iTunes match, only iTunes purchases are stored in iCloud.

If I use the same iCloud account for my ipad and iPhone, will changes I make on one change on the other as well? I'm not sure of the advantage of using teh same iCloud for both devices.
No, it only mirrors changes to synced data. This includes mail, contacts, calendars, reminders, safari bookmarks, notes, iWork documents and data, and photo stream photos (assuming you choose to sync all this data). Changes to iTunes data such as music, apps, podcasts, etc., are not synced using iCloud. In your example, if you delete an app from one device it will remain on the other until deleted there too.

Can an Oracle VM be converted for use in VMWare or VirtualBox?
Does anyone know how to convert / export an Oracle VM for use in VMware Server or in VirtualBox? I've successfully converted VMware images to OVM and VirtualBox images to OVM, but I've not been able to figure out how to get an Oracle VM to convert for use in VMWare or in VirtualBox.
-Dan
Edited by: user723595 on Apr 16, 2010 4:10 PMThe ovs-agent will recognize any strorage device on your VM server which:
a) is unused and free of any partition, so basically a blank drive
b) the drive must be recognized by the multipath daemon, so it must be present under /dev/mapper
So basically, you can't throw in a big drive, partition it, install OVM on it and hope to use the remaining space for your storage pool, you will need the system to recognize at least two independent drives - how ever you going to achieve that is up to you, but the most easy way is to have indeed at least two separate drives installed. -
Hi All,
I am new to TestStand. Still in the process of learning it.
What are Parameters? How are they differenet from Variables? Why can't we use variables for passing data from one sequnece to another? What is the advantage of using Parameters instead of Variables?
Thanks in advance,
LaVIEWan
Solved!
Go to Solution.Hi,
Using the Parameters is the correct method to pass data into and out of a sub sequence. You assign your data to be passed into or out of a Sequence when you are in the Edit Sequence Call dialog and in the Sequence Parameter list.
