Can some one plz tell me which customization tool should be used to package Adobe Audition CS6
Sorry, you will have to give us a LOT MORE DETAIL about what exactly you are trying to do!
As written, I'm afraid your question makes no sense. Why do you need to "package AA CS6"?

Can some one please tell me what is the problem in the below pl/sql block
Hi, I have problem with the following pl/sql block, I need this with bulk operation.
-- Assume the following scenario, we are validating dept (master) and emp(child) which are my temporary tables and updating the status back to
-- dept ( for all the validation errors, even if we have any validation at child it has to update the header record with error message),
-- upon successful validation insert the data into dept3, and emp3 interms of batches
-- I have give the sample example with dept and emp, but i have around 10 million records which has around 30-40 validations,
-- I would like to process them in terms of batches using bulk collection as this would do fast processing
-- Can some one please tell me how to insert them in terms of bulk with every set of 1000 records in each batch in this example,for every set of 1000 records
-- i need update batch id with unique number in dept table
-- with current data i can have 50 batches , I need to pass, deptno as parameter to my emp cursor.
-- can some one please tell me how to make this validation and insertion more efficient. so that while inserting the data for every batch it should insert batch id
-- Tried with LIMIT clause as well but not working
-- I am correcting the code as per your comments Request you to please suggest me so that I can correct , I am new to PL/sql, started learning now.

Message was edited by: 888025Hi, I have problem with the following pl/sql block
Well, as Hoek already said, that is the understatement of the century.
I can't be absolutely certain but I think that set of DDL and code that you posted has just about every possible error and design issue that there is! It would make an excellent addition to BluShadow's FAQs an an example of what NOT to do.
I don't think it is even possible to 'fix the basics first' as Hoek suggested. IMHO the first step needs to be to create a functional requirements document (FRD) that explains in detail WHAT needs to be done. That doc should also contain info about how any errors/recovery/restart is to be handled. It is premature to try to implement ANY solution without first knowing what is needed functionally.
Once the FRD is done you should do a walk-through based on your current architecture and sample data to make sure that the document really covers ALL of the steps that need to be performed and that it adequately explains how to deal with any processing or data issues that might arise.
The next document you need is the TRD - Technical Requirements Doc that covers the different technical implementions of the FRD that can be done and the advantages/disadvantages of each.
Then you can start working on a prototype.
1. The DDL you posted isn't coherent - there are CREATE table statements and then later ALTER statements that add additional columns. There doesn't appear to be any reason for not including ALL of the columns in the CREATE table statement.
2. You are using PL/SQL types instead of SQL types. That makes it impossible to use those types in SQL statements and makes it much more difficult to test since it is much easier to test a query in SQL (e.g. using sql*plus) that to embed the query in PL/SQL.
3. You are defining the same type twice but giving it different names.
TYPE dept_t
IS
TABLE OF dept%ROWTYPE
INDEX BY binary_integer;
TYPE dept_i_t
IS
TABLE OF dept%ROWTYPE
INDEX BY binary_integer;
Those are both based on the same DEPT table! Why the duplication?
Also you are using associative arrays instead of just using nested tables. Get rid of the INDEX BY clause.
4. You have some serious architectural and data model issues
-- Assume the following scenario, we are validating dept (master) and emp(child) which are my temporary tables and updating the status back to
-- dept ( for all the validation errors, even if we have any validation at child it has to update the header record with error message),
Why would you do that? You say 'it has to update the header record ...'. Says who? That is just one indication that you are trying to implement a 'solution' before you have adequately defined the 'problem'.
Typically you would NOT alter any of the data tables; any validation errors/issues would get inserted into a table specifically designed to hold/log those issues. That table would contain key field values to correlate with the source of the error.
Those 'master' and 'child' entities are two SEPARATE things. Issues with a 'master' row have NOTHING to do with any possible child rows.
And issues with a 'child' row have NOTHING to do with any possible master rows. The ONLY connection between 'child' and 'master' is the foreign key that correlates them.
So you don't necessarily have to validate the 'child' rows in sync with their 'master' row. In many cases you would have a procedure that performs validation of the entire set of 'master' rows and log those issues/problems. You would use a different procedure to validate the entire set of 'child' rows and log their issues.
Those validation procedures can often work with ALL of the data using SQL statements instead of bulk processing.
5. You are using loop constructs that are not valid for the type of processing you are using
LOOP
FETCH c1 BULK COLLECT INTO hdr_tbl;
EXIT
WHEN c1%NOTFOUND;
END LOOP;
There can be NO exit since the bulk collect with either get EVERYTHING or NOTHING. Possibly that is just a holdover from your attempt to use the LIMIT clause but you removed that clause from the FETCH; I don't know.
There is so much wrong with what you posted it is really rather pointless to try to 'fix' it.
I suggest you start over and clarify and DOCUMENT the actual requirements without prejudice about the solution that someone seems to want to force on you. -
Can some-one please tell me how to transfer photos from my ipad to my macbook air ? thanks
Can some-one please tell me how to transfer photos from my ipad to my macbook air ? thanks
To copy photos to your Mac that were taken with the iPad, copied to it via the camera connection kit, or saved from emails/websites then see this page - on a Mac you can use Image Capture, iPhoto and Aperture.
To copy photos that were originally synced from a computer you will need a third-party app such as Simple Transfer which can copy them off via your wifi network. But as photos are 'optimised' when they are synced to the iPad, any that you then copy back to a computer may not be exactly the same as they originally were on your computer. -
In new iPad 4g, when sim card is not inserted, I can not find the enable 4g tap in the setting-cellular data tap, can some one please tell me if this is normal and if so, then when it appears, thanks
If the SIM is out of your phone, find my phone needs a data connection, so could use wifi - IF in range of a wifi and one that it can join (ie. a known network or one that is wholly open so no login required). Your phone could also simple be turned off, so not findable, or it may have been restored (plugged into iTunes and restored as new) again, making it permanently unfindable. Honestly, for someone stealing an iPhone, this is likely the first thing they do - restore as new and it is theirs forever.
Find my iPhone is tied to the users iCloud account - the find function is part of the iCloud account's services and it communicates with the iCloud servers over a data connection - either wifi or 3G.
Have you set up your iCloud account on your replacement phone, and is it working properly on that phone? -
I have iphone 4g and have updated to ios6 an updated itunes 2, but while sync itunes freezes and iphone is not sybc fully, finally i have to disconnect my iphone for itunes to shunt down. Can some one please tell why this is happening?
I am having this problem. At first with the new iPhone 5, and then with the iPad 2. I am not sure why this is happening.
My gut feeling is this is an iO6 issue and here's why -
The problem mainly occurs with apps. I have about 150 apps, and when I plugged in the phone, iTunes went to sync all of them. The process would hang up after about 20 - 30 apps were loaded onto the phone. I could tell where about the process hung up because the apps on the phone showed up as "waiting".
Then on the iPad 2 I plugged in to sync and saw there was a huge "Other" component in my storage. It required me to restore the iPad 2 from backup. With this restore the same issues occurred - putting the apps back on the iPad would hang up. The videos on the iPad also got stuck - maybe after about 10 hours of videos transfered iTunes crashed.
My solution has been to soft reset the device, restart Windows, and continue the process until it's complete. This is remarkably inefficient and time-intensive but everything works with patience.
I have been wondering if others have had these same problems. -
Can anybody help I have no sound apart from wen I use it threw Bluetooth
Hi Donh1981,
I apologize, I'm a bit unclear on the exact nature of your issue. If you are saying that you are not getting any sound from your iPhone through either the external speaker or the headset jack, you may find the troubleshooting steps/articles listed in the Acoustic section of the following article helpful:

Can some one please tell me how to apply wine on apps?
i have downloaded wine but i dont know how to use it????can someone please help me....
First, WINE is almost completely useless except for running the Windows version of Microsoft Office (which you have no reason to do) and some games.
If you want to do the latter, you should test a commercial product called "CrossOver Mac." -
I have had my IPhone 4S for a little over a week now. My battery life was at 90% It Died, Dead, Does not work at all. Can someone tell me what in the heck is going on here. I have had all of the Apple Phones and They all had their little quirks..But This is ridiculous is it just with the Black 4S or the White 4S or both. Help?
The Basic Troubleshooting Steps are:
Restart... Reset... Restore from Backup... Restore as New...
Restart / Reset
http://support.apple.com/kb/ht1430
Try this First... You will Not Lose Any Data...
Turn the Phone Off... ( if it isn’t already )
Press and Hold the Sleep/Wake Button and the Home Button at the Same Time...
Wait for the Apple logo to Appear and then Disappear...
Usually takes about 15 - 20 Seconds... ( But can take Longer...)
Release the Buttons...
Turn the Phone On...
If that does not help... See Here:
Backing up, Updating and Restoring
http://support.apple.com/kb/HT1414
If you try all these Steps and you still have issues... Then a Visit to an Apple Store or AASP (Authorized Apple Service Provider) is the Next Step... Be sure to make an appointment first... -

Windows on Intel Macs
There are presently several alternatives for running Windows on Intel Macs.
1. Install the Apple Boot Camp software. Purchase Windows XP w/Service Pak 2 or Vista. Follow instructions in the Boot Camp documentation on installation of Boot Camp, creating Driver CD, and installing Windows. Boot Camp enables you to boot the computer into OS X or Windows.
2. Parallels Desktop for Mac and Windows XP, Vista Business, or Vista Ultimate. Parallels is software virtualization that enables running Windows concurrently with OS X.
3. VM Fusionand Windows XP, Vista Business, or Vista Ultimate. VM Fusion is software virtualization that enables running Windows concurrently with OS X.
4. CrossOver which enables running many Windows applications without having to install Windows. The Windows applications can run concurrently with OS X.
5. VirtualBox is a new Open Source freeware virtual machine such as VM Fusion and Parallels that was developed by Solaris. It is not yet fully developed for the Mac - some features are not yet implemented - but it does work otherwise.
6. Last is Q. Q is a freeware emulator that is compatible with Intel Macs. It is much slower than the virtualization software, Parallels and VM Fusion.
Note that Parallels and VM Fusion can also run other operating systems such as Linux, Unix, OS/2, Solaris, etc. There are performance differences between dual-boot systems and virtualization. The latter tend to be a little slower (not much) and do not provide the video performance of the dual-boot system.
See MacTech.com's Virtualization Benchmarking for comparisons of Boot Camp, Parallels, and VM Fusion.
Boot Camp is only available with Leopard. The Boot Camp Beta that was used with Tiger has expired and is no longer available for use. So contrary to the other poster's comment, Boot Camp isn't truly "free." You must purchase Leopard to get it. -
Can some one tell me a better way...
Hi All..
I work on a web application. I create user ids for people logging into my application. here I have a small problem.. This is what I am currently doing...
When I create a new user, I assign a new user id to the user and store all hi info.
All our user ids are stored in User_ID table and user info in User_Info table.
First I get the max user id from the User_Id table.
int iuserid = select max(User_ID) from User_ID;
Then I add ' 1 ' to this and assign it to new user.
iuserid = iuserid+1;
insert into User_id values(iuserid, <ssn> );
Then I store all user info in User_info table..
insert into User_info(iuserid, <first_name>, <last_name>,...);
Both these SQLs are executed as a transaction.
The problem that I have...
It works fine in a normal environment and in my testing.
But when the load inceases, before I insert into the User_info, another user tries to get the max User_id from User_ID table, then it conflicts..
I have seen occurences of User_Info storing the info of a different user against the User_id when many people are accessing the app at the same time.
Can some one tell me a better way to handle this scenario..
Appreciate all you help..
TIA..
CKHi,
assuming that the requirement for user_id is only for uniqueness (primary key requirement) not continuosly.
perhaps can try this,
1) create a table to keep the max id for each table's key.
e.g.
create table key_id_lookup
key_name char(n),
current_value number(m)
where n & m is the size of the field
2) for each creation of entry in the user_id table, lookup the value in the key_id_table and increment it after retrieval.
e.g. current_id = select current_value from key_id_lookup where key_name = 'user_id_key';
current_id+=1;
update key_id_lookup set current_value = current_id where key_name = 'user_id_key';
something similar to use of sequence if your database support it.
3) continue with the creation of record in other tables. now obtain the time stamp of creation and append with the current_id obtained. e.g. timestamp = 132456872; size of m is 5, user_id = 132456872 x 100000 + current_id;
this should give you a unique key at creation time.
There should be other better ways of resolving this(like locking the table for the update operation but affect performance, etc), depending on the feature supported by the database in use.
Hope this can help as last resort if other options not available. -

That's an entirely different issue, unrelated to your iOS devices.
