Does OC4J has a JDBC realm ? can some one clearify ?

Hi
Thank you for reading my post
does Oracle application server 10.1.3.1.0 (the new developer preview version) has JDBC realm ?
where i can find it?
thanks

Hi,
A Realm is a collection of resources that are controlled by a defnied policy. You can use JNDI to lookup OC4J realms.
I think you are referring to the DataSources in OC4J. You can get more information about DataSources at this link :-

Hi bibisandoval,
Thanks for visiting Apple Support Communities.
If the movie has completely downloaded, I recommend deleting the movie and downloading it again from your list of purchased movies. See this article for the steps:
Downloading past purchases from the App Store, iBookstore, and iTunes Store

If you are still not able to play the movie, you can report an issue with this purchase using the steps in this article:

You're in the wrong forum. Post to iPhoto for iLife, not iPhoto for iOS.

HT1373 Can some one please assit me. I have purchased a new laptop and copied accross my file of music from Itunes I can see the music in my files, however i can copy music from CDs, however the Itunes file does not connect or will not interface into itun

Hello can some one assit me please. I have purchased a new lap top and copied my old itunes files accross so i do not loose all my music, and have to start again. I can play and see allof my tunes and play these. However I am unable to access the Itunes store through my itunes files. It will not interface at all. I can access itunes store through the Web, but not through the my ituntes file. I have gone in and authorised the laptop through the various process. Highly frustrated already paided a computer person to fix this. However hed deleated all files and started again he had it work and then I turned computer on again and it will not interface from the itune file to itunes, So if I copy a CD it will not tell you the name of the track. I cannot asscess the itunes store to action anything. Please assit me
Regards
Karen

I am not an expert, but assuming that you have a Windows or Mac folder with music in it and want to move that to a new laptop, I think you have to import it into iTunes. iTunes needs to associate each file with a link, so copying it over will not associate a link.
Delete the files and try importing.

Please please can some one tell me how do you charge ur ipad with ur laptop. it doesn't chage wen I put use the wire. only charges when I plug the socket in.

please please can some one tell me how do you charge ur ipad with ur laptop. it doesn't chage wen I put use the wire. only charges when I plug the socket in. Iv never used an ipad b4 so don't really know much. Hope some one knowz.

The quickest way (and really the only way) to charge your iPad is with the included 10W or 12W USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (2.5W, most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.

At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night.

I was facing problem while connecting to oracle database.Can some one help me soon!!!!!

Hi all,
I was facing problem from last week.Suddenly i was getting ora-12505 error while connecting to the database through toad.I tried to change tnsnames.ora & listener.ora in multiple ways,but no luck...Inspite i was getting different errors like ora - 01034: ORACLE not available / ora - 27101: shared memory realm does not exist...When i try to connect using sys / sys as sysdba,connection is establishing and when issue the command startup it was throwing the error ORA-01821: date format not recognized......Fed up solving these issues....Can some one help me out...It's very very urgent..
Thanks in advance,

Well, the obviously solution is to use separate Apple ID's for iCloud.

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..
CK

Hi,
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.

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.

Hi, 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

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.

hi Samberl
thanks a lot for the fast reply.
I was dragging folders from main folders on the laptop-desktop onto the external drive icon - to copy them across....
Your suggestion sounds very promising - I didn't know about 'cloning'.
Yes the idea is to backup the laptop -    I thought I would just move it all now, new - and then keep saving/dragging physically   across to the new drive myself each day or two...
Would this be the sizeof the internal hard drive = c.500 gb ?   =   under the HD icon on desktop is written :
" 499.76gb , 311.5 gb free "
I can erase and start agin on the new external drive - so this plan is to make two partititions, rather than the one at present, and make one of them 500 gb ?
I have found CCC [carbon copy cloner] googling - looks good.
When CCC site says it backs up the hard drive - would this mean all my files [over 100 gb] that are mostly in folders on the desktop, plus the others in itunes, iphotos etc found in the HD icon, would all copy across successfully [wherever they are in the computer ] ?
thanks again, hope you can clarify these things and then I will go for it.
It would be great and amazing if this 'lack of permission' message doesn't show up in the process of doing this ccc transfer - hopeful!

I am not able to install my 'Complete National Geographic' cd on my Mac mini which runs Lion OS. The error message I get says 'Can't open installer as classic environment is no longer supported' can some one suggest a solution

I am not able to install my 'Complete National Geographic' cd on my Mac mini which runs Lion OS. The error message I get says 'Can't open installer as classic environment is no longer supported' can some one suggest a solution.

It means the software is PowerPC code, which is no longer supported in Lion. Your choices are to go back to Snow Leopard, run Snow Leopard Server in a virtual machine within Lion, see if the vendor has an updated version of National Geographic that will run on an Intel Mac, or run the software on an older Mac separately.

HT1338 After I installed OS X Mountain Lion system, I can't use my Safari to log into my online banking and some other websites which require passwords. Can some one please help?

After I installed OS X Mountain Lion system, I can't use my Safari to log into my online banking and some other websites which require passwords. Can some one please help?

It could be browser incompatibility or something else. When you say you can't log in, what happens? Is the bank website generating an error saying you're not using a supported browser? Does the login form for your bank account display as usual, but once you submit the form to log in it doesn't work? Give me a specific step-by-step of what you're doing, such as...
1. I load bankofamerica.com
2. I type in my login
3. When I submit, the page does nothing
Obviously that may not be your issue, but giving us details like that will help us come to a quicker conclusion.

I would like to use an external monitor (plasma tv) with my MacBook Pro also, which has a resolution 1365x768 - a resolution which is not available under the Display Preferences. I can use the plasma at a 4:3 radio resolution, but I don't see ANY 16:9 radio resolutions available.
Have you found a solution to this yet?

Can some one explain each line of this abap code

Hi..
I got this code from a document, where they try to add account group (LFA1-KTOKK) to 0VENDOR_ATTR. I have no idea of ABAP syntax. Can some one tell me the meaning of each line of code.
Tables: LFA1. "vendor master data table
data: l_tabix like sy-tabix.
case i_CHABASNM.
*Enhancement of Vendor Master Record
 WHEN '0VENDOR'.
 case i_datasource.
 WHEN '0VENDOR_ATTR'.
 data: l_s_BIW_LFA1_S like BIW_LFA1_S.
 loop at i_t_data into l_s_BIW_LFA1_S.
 l_tabix = sy-tabix.
 select single * from lfa1 where LIFNR = l_s_BIW_LFA1_S-LIFNR.
 if sy-subrc = 0.
 l_s_BIW_lfa1_s-ZZacctgrp = lfa1-ktokk.
 modify i_t_data from l_s_BIW_lfa1_s index l_tabix.
 endif.
 endloop.
 endcase.
 endcase.
Thanks in advance.

Hi
Tables: LFA1. "vendor master data table
"here by saying Tables they have delcared the LFA1 table for further use in the program"data: l_tabix like sy-tabix.
"here they have defined own table index by copying the structure of system index"case i_CHABASNM.
"when character"
*Enhancement of Vendor Master Record

"here it says that its 0vendor"case i_datasource.
"when this datasource"
WHEN '0VENDOR_ATTR'.
"when datasource 0vendor_attr"
data: l_s_BIW_LFA1_S like BIW_LFA1_S.
"here we are declaring an internal table like BW internal table"loop at i_t_data into l_s_BIW_LFA1_S.
"here looping at i_t_data table data into l_s_BIW_LFA1_S".l_tabix = sy-tabix.
"here we are saying that our defined table index is equal to system index"select single * from lfa1 where LIFNR = l_s_BIW_LFA1_S-LIFNR.
"selecting single rows from table lfa1 where lifnr is equal to l_s_biw_lfa1 field s-lifnr"
if sy-subrc = 0.
"if system field returns 0 that means the above line has been executed"
l_s_BIW_lfa1_s-ZZacctgrp = lfa1-ktokk.
"internal table field is equal to lfa1 field."
modify i_t_data from l_s_BIW_lfa1_s index l_tabix.
"changing the internal table data as per i_t_data"endif.
endloop.
endcase.
endcase.
THIS IS MY UNDERSTANDING PLEASE KINDLY CORRECT ME IF I AM WRONG.
