What resources are used for "create index" ?

In the context of creating an index on a heavily loaded table....
What Oracle resources are consumed>? Any caches or buffers? Sort files? Temp Tables?
(trying to speed up an index create)

Like any other read/write database activities, CREATE INDEX uses blocks in the buffer cache. If your table is large, I would recommend increase your buffer cache.
No temporary tables is used as far as I know. There are no sort files in Oracle. Temporary tablespace may be used because sorting is generally needed when creating an index, but I am not sure about that.
When creating a index, Oracle creates a temporary segment in your permanent tablespace: if the CREATE INDEX fails, the temporary segment is removed. If the CREATE INDEX succeeds, the temporary segment is made permanent.

What is the use for CREATING VIEW WITH CHECK OPTION?

Dear Legends,
I have a doubt
What is the use for creating view?
A: First Data Integrity, Selecting Particular Columns..
What is the use for creating a view with check option?
A: As per oracle manual I read that its a referential integrity check through views.
A: Enforcing constraints at DB level.
A: using CHECK OPTION we can do INSERTS UPDATES for a view for those columns who have no constraints... is it right??
A: If we do a INSERT OR UPDATE for columns who have constraints it will show error... is it right???
Please clear my doubt's Legends
Lots of Thanks....

Hi, Karthick,

... What is the use for creating view?
A: First Data Integrity, Selecting Particular Columns..Most views are created and used for convenience. A view is a saved query. If the same operations are often done, then it can be very convenient to code those operations once, in a view, and refer to the view rather than explicitly doing those operations.
Sometimes, views are created and used for security reasons. For example, you many want to allow some users to see only certain rows or certain columns of a table.
Views are necessary for INSTEAD OF triggers.
What is the use for creating a view with check option?
A: As per oracle manual I read that its a referential integrity check through views.The reason is integrity, not necessarily referential integrity. The CHECK option applies only when DML is done through the view. It prohibits certain changes. For example, if a user can't see certain rows through a view, the CHECK option keeps the user from creating such rows.
A: Enforcing constraints at DB level.I'm not sure what you mean. Please give an example.
A: using CHECK OPTION we can do INSERTS UPDATES for a view for those columns who have no constraints... is it right??No. Using CHECK OPTION, you can do some inserts and updates, but not others. The columns involved may or may not have constraints in either case.
A: If we do a INSERT OR UPDATE for columns who have constraints it will show error... is it right???If you try to violate a constraint, you'll get an error. That happens in views with or without the CHECK OPTION, and also in tables.

What techniques are used to create these images?

The artist who created the pictures shown on the links below uses Photoshop. Does anyone know what tools are used for this?

Did you click on each of those images to see them reach full size in Flash animation?
Here are crops from the bottles and cell phones at 100% resolution:
The Flash zoom-out and zoom-in animation is done in programming the code of the web page, as you can see by "Inspecting the Element" on the web browser page:
I cannot give you any further information or assistance, as I don't deal with web programming.
As far as I can tell, the "technique" used here is pretty straight forward:
Take a picture with a digital camera, then program the web page to repeat the image a bunch of times and display the zooming in and out in Flash animation.

What ports are used for handshaking signals?

I want to use Handshaking Digital I/O on an AT-MIO-16DE-10, and I want to know if there are extra digital I/O lines used for this, or if there are independant handshaking connections. I can't seem to find any documentation which warns that you can only get 7 bits out of a port if you use handshaking. Or you can only use ports 2,3,4 because port 0 is used for the handshaking signals.
Any hints would be appreciated.

Great, actually, I found this information, and would like to re state my question. Now that I know what ports I should be using (this is described in detail in the hardware manual for the E series), I would like to see some definite information about what I must do in my external device to make use of these signals.
I'm a little confused by some comments in the documentation that some of the facilities of Port C (on the 8255) are only avialable if I use register level commands (as if using the parallel port). If I use the DIG_Prt_Config and set to handshaking (input) on a port, then I assume I set up my external hardware as if Port C was in Mode 1(input), and then follow the timing described in the E Series manual.
It's just a shame that everything o
n the PC side is well described, but there are no application notes that I can find about building an external device that can use the handshaking signals.
If 'you' (anyone) can confirm what my assumptions, or point me in the right direction, I would appreciate it greatly.
Thank you.

Anyone know what these are used for??

Hi All,
I am putting together some documentation for a CUP implemenation and I have come accross three configuration options in CUP that I have no idea what they pertain to and I can't find any documenation on them.
1. What is the "SAP EP LDAP" connection type used for?
2. What are SOD Review Process Rejected and UAR Review Process Rejected background jobs used for?

About "What are SOD Review Process Rejected and UAR Review Process Rejected background jobs used for?", I just talked to an SAP person today to explained to me that this is a job your sec admin would run for example in a UAR review when a particular user in a request had been "rejected" (e.g. "this person doesn't work for me, so I need to reject him so he can get sent to the right mgr"). When the reviewer (mgr) rejects the user, then the admin figures out based on the reason (e.g. changed jobs, terminated, etc) what action to take. For instance may be to cancel the request for termination. If the user has changed jobs, then the sec admin would need to go to the LDAP (or whatever source you use) to fix up the mgr<->employee relationship info, then run this "Process Rejected" job. The rejected user will then be put into a new request, and the rest of the original request can be processed by the 1st mgr. I haven't tried all this yet, but sounded reasonable to me...

What accounts are used for video iChat between two Macs?

I need to set up video iChat between a 10.6.8 Snow Leopard laptop and a 10.5.8 iMac. The machines are not on the same network. I have read all the posts and the help for iChat but the explanations of accounts are confusing. What accounts can be used for Mac-to-Mac video chat and how do we set them up?

Hi,
AIM or Jabber.
AIM valid accounts include any @mac.com ID (Lapsed, paid for (originally) or a Trial account) Any @me.com account that was linked to iCloud at the change to iCloud from MobileMe. And of course any @icloud.com ID.
If you have an Apple ID that started as one of these and "Migrated" to the other services other the years and is linked for Email they will work as separate IDs/Valid Screen Names with the AIM servers.
Effectively this then works Mac to Mac in Messages or iChat.
Jabber IDs.
Many servers http://www.jabberes.org/servers/ (this is only some and the site also list many that are Off line)
Also Google run what was called the GoogleTalk server which means Google Mail IDs can be used as Jabber IDs
Facebook run a separate Chat ID/Server which you have to sign up for at Facebook.
AS most server are what is called "Federated" you can add Jabber Buddies form one server to a Buddy List of another.
Therefore you may have a Google Buddy list as such but you can add Facebook Buddies or other Buddies on other Jabber servers.
Audio and Video Chat are Mac to Mac. You cannot Video or Audio chat to Web Browser login even if the Browser has the video plugin for that service (Basically web browser to web browser chat require the Video plugin for that service/server).
FaceTime will not work.
You can download FaceTime for the Snow Leopard Computer as it is an Intel only app.
However it cannot be downloaded for the Leopard computer.
Summary.
You may have IDs that will work in iChat 4 and 5 already (Apple IDs as AIM Names or Googlemail or Facebook IDs)
Chats are then Mac to Mac (and also AIM to AIM or Jabber to Jabber but not AIM to Jabber).
iChat will allow you also to do Screen Sharing as well as Audio Only chats

Does anyone know what software is used for creating this?

I have seen this effect on a few television adverts and wondered how I would go about creating it.
In this click the ball is kicked and as it gets to the screen it "breaks" into pieces and the ball comes out of the screen - I know this isnt the same ball as seen in the clip and it had been recreated in probably a 3d package such as cinema 4d but how do I get the breaking into pieces like that -
http://img226.imageshack.us/my.php?image=picture1ij2.png
In this clip the person just starts breaking into pieces -
http://img227.imageshack.us/my.php?image=picture2gc2.png
I guess they are both done using the same software and effect and all I really want to know is the software and effect used. Any additional help would be appreciated but I would like to try and work out the rest for myself - I'm halfway along a learning curve!
PS - Both stills are taken from the OneSize Showreel.

Well, After Effects has a shattering effect, but I'd guess it was a 3D app that created those effects. To see what you can do with Motion, check out this thread:

HT6160 What ports are used for Apple Configurator to function with IPads?

Need to know what ports need to be allowed for Apple Configurator to function.

Apple Configurator runs locally on an OS X computer. It requires a USB connection. So no ports required for connecting Configurator to iPads.
However, there are some ports that need to be opened for iPads to work with Apple's server if you are behind a firewall. Here is a list of known TCP and UDP ports used by Apple software products: http://support.apple.com/kb/HT6175?viewlocale=en_US
To use iPads behind a firewall (Configurator or not), you'll want to definitely open 5223 for Apple Push Notification and the standard ports for HTTP/HTTPS (80 and 443). If you're using an MDM, you will likely need to open 2195 and 2196 as well. If you still have issues port watch and see what an iPad does when trying to get to the store.
Hope this answers your question!

When dragging photos to desktop, what settings are used?

When a photo is dragged out of iPhoto and dropped anywhere in the Finder, what settings are used for that implicit export? E.g., what JPEG quality? It seems to export the full size.
Can't seem to find this documented anywhere!

In tests Old Toad reckoned that it was equivalent to about 8 on Photoshop's scale of 12.
Typically when I export via the file menu I select the highest quality. If iPhoto uses something less than that, then I'll stop dragging and return to the file menu export.
Doesn't quite work like that.
If you have an edited photo then there is a single generation of compression applied. If you export at any setting other than Maximum the file will be smaller. At maximum the file will quite likely be larger - less compression applied to the data.
As to which is best to use? Depends on what you're using this jpeg for - but remember this, exporting via dragging gets none of the metadata you've added in iPhoto (Keywords, Location, titles, descriptions etc)

What PDF settings are used when creating DPS articles?

When you create a PDF file using Acrobat Distiller or InDesign you can modify settings such as font subsets, image down-sampling and compression which will have an impact on the final file size. Does anyone know what settings are used when articles are rendered in PDF format in DPS and can the settings be modified? Specifically, what type of compression is applied to images? If I were to place two images on a page, a png and a jpg with medium quality, would they be embedded in the PDF as is or re-compressed in another format and/or level of quality?

Thanks for your help.
So images placed in an InDesign retain their original file format and are unzipped when the article is loaded in the app.
I'm assuming that if compression is applied to the original image files it can have an impact on performance. If you were to use jpeg files in a document they would need to be unzipped and decompressed. I've read other forum posts that suggest the iOS jpeg decompression engine is too slow to present a fluid user experience in a DPS app. The combined processing time of unzipping and decompressing jpegs files may steer me towards the png format.

What port numbers are used when creating temporary queues

Using the following code as an example, what port(s) are used when creating temporary queues? Is it a range of ports? Is it random? And is it configurable? If you have any insight on this, please let me know. Thanks.
QueueConnection con = connectionFactory.createQueueConnection();
QueueSession session = con.createQueueSession(true, Session.AUTO_ACKNOWLEDGE);
TemporaryQueue replyQueue = session.createTemporaryQueue();

The only ports I know about are the defaults ports:
JMS 7676
IIOP 3700
Are these the only ports that are used, even for temporary queues?

What the steps are useful for us while designing the database by Performanc

Dear Experts
Plz tell me.
What the steps are useful for us while designing the database by Performance point of view.
Like Proper indexing and table assing to specific tbalespace etc

Oracle manuals would do the best for you. There is no step by step rules for tuning the database , had this be true , then Oracle must've write a programme , application or sql script to achive it . I would advise you to go through oracle performance and tuning guide .

What cast type are used for?

In the example attached to this question is a simple VI application that cast, using type cast of LabVIEW, one value to different other type. My understanding of type cast, in C, C++ and to my best knowledge, was an implicit adaptation of a numerical value in a specific format to an other format. The value should remain the same. Unless the type in which the value is assigned is not enough large or adapted to contain such a number ex:
I8 = 500;
U32 = -1;
But in my example all the assigned indicator are large enough.
I have the same problem in LabVIEW 5.1.1 and 6.1
If someone could only tell me what it is used for?
Best regards,
Nitrof

The type cast function is really helpful for typecasting "unusual" data to a more convienient data format. It can also be used to coerce data, like in your example, but coercion is usually not always a good thing because it can cause bad values.
There are lots of good examples of typecasting.
For example, I use the typecast function to change refnums to unsigned 32 integers (U32), just so I can pass the refnums between VI's easier.
Another VERY common typecast is if you want to display the ASCII value of a character. Run the string character "A" into a typecast, and set the output type as a Unsigned 8 bit number (U8), and you will see 0x41. Take a look at my example VI's to see what I mean.
