Question about "Create Item" page

Im working on trying to Insert a new item into a Self-Service Web Applications page.
As part of my research, I have been looking at this doc:
Oracle® Application Framework
Personalization Guide
Release 11i
Part No. B25439-02
From:
http://download.oracle.com/docs/cd/B25516_18/current/acrobat/115fwkpg.pdf
The document does not seem to go into much detail about how to Insert an item on a page. I also checked the "OA Component Reference" document.
I checked the online help via "Create Item Page" - e.g.
http://oursite/pls/PSAT/fndgfm/fnd_help.get/US/FND/CUST_PERSADMIN_CREATEITEM.HTM
Again, that doesn't give a lot of information.
As part of my testing / research, I would like to add a new Item to a page, and have the value of the item to be taken from an existing SQL Query.
For example, in iProcurement, when viewing a Requisition Details, e.g. via this page:
http://oursite/OA_HTML/OA.jsp?page=/oracle/apps/icx/por/reqmgmt/webui/ReqDetailsPG&reqHeaderId={!!BX6R96mkQOcfNZ60BeTaJQ}&retainAM=Y&addBreadCrumb=Y&_ti=245778094&PersonalizationParam=PersonalizationParamAdmin&oapc=12&oas=mYF7zP1VI7xoAWcUQHTEkQ..
I would like to add in the "NOTE_TO_AUTHORIZER" field from the "po.po_requisition_headers_all" table.
From looking at the "About this Page" link, I can see there is a View Object called "oracle.apps.icx.por.reqmgmt.server.ReqHeaderVO".
This ViewObject contains an Attribute called "NoteToAuthorizer" with a Type of "java.lang.String".
When I go to the "Create Item" page, and choose and Item Style of "Message Styled Text" there seems to be no way to say which database field you want to include.
From looking at a previous customisation that a developer did, I can see you can pull in an Attribute via the "View Attribute" field, and link in the VO via the "View Instance" field.
When inserting database values into a Self-Service page, can we only insert Attributes, and not any of the other regular fields from View Objects?
Apologies for the rambling essay.
Any advice much appreciated.
Thanks

Hi Jimr,
In OAF sql queries are represented by View Objects and columns of query will be represented by View Attribute.
For every column in query there will be corresponding view attribute name, so while adding any item on self service page which represents data from database you need to specify view instance name and view attribute name, which will specify which column and from which query it will show the data.
*"When I go to the "Create Item" page, I can't work out how to tell Oracle that the Item I want to create should be the "NoteToAuthorizer" field from the "ReqHeaderVO" ViewObject."* so ReqHeaderVO1 will be the instance(by default OAF generates instance like this) and "NoteToAuthorizer" can be mentioned in View Attribute name property.
Let me know if you need further clarification.

A question about creating packages as local objects in ABAP

Hi,
I have a question about creating packages with SE80. Whenever I create a new package it is assigned a new transport request. After that, I can create new programs inside this package, and each time I can choose whether to assign the new program to a transport request or just save it as a local object (I often do this for test programs that I don't transport and I remove them once my tests have been done).
What I would like to ask is that, is it possible to create a package (and not just programs inside a given package) as a local object? so that every new object created in this package will be considered as a local object?
Thanks in advane,
Kind Regards,
Dariyoosh

Please also check the F1 help for the package field e.g. in SE80, SAP standard is in range A-S and U-X, namespaces start with "/", so you should be save. I am using the T namespace for temporary stuff since a long time and did not have a problem so far.

Thank you very much for this remark, I checked F1 help for the package field and in fact as you mentioned these ranges are for local objects.

Customized "create item" page

I have a issue to create a item in a custom item type.
this item type is complex, and i think it need a customized create item page.
but i can not find document for this.
another way is write a web app and do this job with portal's plsql api.
still a problem: how can I set context?
wwctx_api.set_context() need both user and password, how do i get that password?
any sugguestion?

Hi Peter,
If you want to access specific Portal resources in PL/SQL from any client other than your browser, you will need to use the API function wwctx_api.set_context(). Examples are accessing WWSBR_ALL_ITEMS when connected to the database with SQL*PLUS. There is no need to use this function if you are running e.g. a PL/SQL item from your browser. The context is automatically set.
The function wwctx_api.set_context() indeed requires the SSO password. If you really need this functionality without supplying a password, you can use the unpublished API call wwctx_api_private.set_context(). Notice however that this one is unpublished and therefore unsupported to be used. Oracle can change this API without further notice.
Hope this helps,
Erik

Question about printing by page count

Hi
I'm new to this and I have a question about printing our invoices by page count.
We generate our invoice using Crystal 2008 we have invoices that can range from a single page to as many as 6 pages. I would like Crystal to preview/print the reports in order of how many pages are in the report. Example: print all single page invoices first then all invoices that are 2 pages and so on. Is this possible?
Thank you in advance

Hi Ido,
Thanks for your input. This is more or less what Carl was suggesting yesterday and I gave it a lot of thinking. The problem here is that I cannot go with "good enough resolution" - I need perfect resolution.
The reason for this apparently silly requirement (why would one sort a bunch of invoices by number of pages instead of Customer Number, as long as they end up in an envelope anyway?) is the proposed purchase of a folding/stuffing machine which could do very fast what now takes one person 4 days to achieve.
One type of machine comes with three settings - fold/stuff 1, 2 or 3-page statements. You need to have three stacks with all the statements that have 1, 2 and 3 pages. The ones with more pages will have to be folded manually, but there are only about two dozen clients that give us that much business. You feed the machine one stack at a time and set it to process the respective number of pages. Any statement that falls accidentally in the other stack will either cause the whole rest of the stack to be mixed up, which is very bad, or cause one customer to receive his invoice and someone else's, which is just embarrassing. I cannot afford any of these scenarios.
Given that the statement contains variable-length (and depth) messages that vary by month and by profit center, and it could also contain one or more groups of details, each with its own header, it is very risky to try to come up with magic numbers attempting to estimate the number of pages based on the number of detail lines. Someone will still have to eyeball very carefully the initial stack of statements in the areas where the number of pages increases by one and make sure that ordering by number of detail lines did not mix, for example, one report with two pages among two reports with one page. Of course, this increased scrutiny will be necessary only around the areas where the page number transitions from 1->2, 2->3 and 3->4, which is much better than trying to order by number of pages all 1500 statements, but still depends on one's manual intervention and focus and, as a result, makes me pretty uncomfortable.
I have taken a look at the "Group Sort Expert". If you select the "All" option (all groups) and you had some kind of summary value then you could sort the report by that value. The idea was to create a hidden Average field over the TotalPageCount runtime variable (which will always equal the TotalPageCount for that customer, since it's the same for all the pages in that group) and use that summary field in the "Group Sort Expert", which would have solved the problem elegantly. Unfortunately, there is no way to create a summary field over a runtime variable. I even created a formula that just returns the TotalPageCount, but that formula did not show up in the list of fields available for summarization (while other formulas did).
It looks like the reporting engine does not allow this type of "late-sorting". I wonder if it is possible at all, because in effect this would require the engine to execute an additional pass: first it should somehow generate the whole report grouped by Customer Number so it knows how many pages are in each group, then it should sort by the number of pages and only after that it could render the report. I'm not sure the engine can do this additional pass.
I would be very curious to hear about the other (more complex) ideas you mentioned. For example, I have seen (in Crystal 2008) a checkbox allowing "sorting by a formula". I don't know how to write a formula used in sorting, but the basic question in the paragraph above still stands: does the engine even support such a feature?
Thanks again.

A question about creating READ ONLY users.

Dear all,
I have a question about read only user accounts and I would appreciate if you could kindly give me a hand. I have a schema named SCHEMA1. Whenever I want to connect by using sqlplus I run the following:
sqlplus user1/[email protected] SCHEMA1.WORLD is the entry in the tnsnames.ora referring to the schema SCHEMA1.
I need to create a read only user who is able to SELECT all tables and views created by user1 on SCHEMA1 (this user will not modifiy anything at all. The user is used only for a person using SQL queries to read data). for several tables I write the grants explicitly, for example:
CREATE USER user2 IDENTIFIED BY user2;
GRANT CREATE SESSION to user2;
GRANT SELECT ON S001_COR_ECLASS TO user2;
GRANT SELECT ON REF_ECLASS511 TO user2;Is there anyway to do the same thing but for all the tables (because there are a lot of tables and views)? Besides, even with these granted permissions when the user connects with SQL Developer to the database, he is not able to view the list of tables/views in SQL Developer GUI. What causes this problem?
Thanks in advance,
Dariyoosh

Hello Dariyoosh,
he is not able to view the list of tables/views in SQL Developer GUIyou can either go to "Other Users" - user1 - tables. There you see every table you have permission to select.
Or you can create a synonym in schema2 for each table in schema1 and set a filter on the tables node of user2 "Include synonyms".

Question about creating objects in Forms 6i

Hi,
I'm trying to create by code dynamic items in a form, but I don't find the way to do it, or any tutorial in the internet.
Taking a look at the Forms Help it says 'Once you create a data or control block, you can create items in that block at any time. Create items via the Object Navigator by inserting them under the desired block, or via the Layout Editor by drawing them on the desired canvas.'
Is there a way to create items and assign them to datablocks by code? something like CREATE_ITEM?
All I want is a button that inserts textboxes in a canvas, as many items as you want.
Thank you in advance

Hello,
There is no Create_item() built-in to create item at runtime.
You can create hiden item at design time then show them at runtime.
Or you can use some java code to create component at runtime.

Hi, Ali.
There is a great Microsoft web site with free training and tutorials on creating ASP.NET web applications.
http://www.asp.net
Here are also a couple of tutorials to get you started. You have to learn a few topics to create a web application.
Microsoft has recommended that beginners/non-professionals start using WebMatrix as a web editor. You could look at samples based on that with Razor or instead use Visual Studio as an editor. Here are some free training videos from PluralSight to get you
started:
http://www.asp.net/web-pages/pluralsight
Alternately, here is a tutorial on ASP.NET membership:
http://www.asp.net/web-forms/tutorials/moving-to-aspnet-20/membership
And another tutorial on data source controls, which includes the AccessDataSource control:
http://www.asp.net/web-forms/tutorials/moving-to-aspnet-20/data-source-controls
I am suggesting these training materials and tutorials because the steps involved to create a full web site with authentication and authorization would be many and would require more questions/answers.
Besides - this forum is for training and certification. Check out the awesome ASP.NET forums here:

Questions about creating a foreign key on a large table

Hello @ll,
during a database update I lost a foreign key between two tables. The tables are called werteart and werteartarchiv_pt. Because of its size, werteartarchiv_pt is a partitioned table. The missing foreign key was a constraint on table werteartarchiv_pt referencing werteart.
Some statistics about the sizes of the mentioned tables:
werteart 22 MB
werteartarchiv_pt 223 GB
werteartarchiv_pt (Index) 243 GB
I tried to create the foreign key again, but it failed with the following error (Excuses for the german error message):
sqlplus ORA-00604: Fehler auf rekursiver SQL-Ebene 1
sqlplus ORA-01652: Temp-Segment kann nicht um 128 in Tablespace TEMPS00 erweitert
The statement I used:
alter table werteartarchiv_pt
add constraint werteartarchiv_pt_fk1
foreign key (schiene, werteartadresse, merkmale)
references werteart (schiene, werteartadresse, merkmale)
on delete cascade
initially deferred deferrable;
So the problem seems to be, that Oracle needs a lot of temporary tablespace to generate the foreign key and I do not know how much and why.
My questions now are, and hopefully someone is here, who can answer all or a part of it:
1) Why does Oracle need temporary tablespace to create the foreign key? The foreign key uses the same columns like the primary key.
2a) Is it possible to tweak the statement without using the temporary tablespace?
2b) If it is not possible to avoid the usage of the temporary tablespace, is there a formula how to calculate the needed temporary tablespace?
3) Is it possible to modify data in the tables while the foreign key is created or is the whole table locked during the process?
Any help or hint is appreciated.
Regards,
Bjoern

The foreign key uses the same columns like the primary key.Because it's validating the data to ensure the foreign key won't be violated. If you had specified ENABLE NOVALIDATE when creating it then the existing data in the table wouldn't need to be checked and the statement should complete instantly (future data added would be checked by the constraint).

Very Nube Question About Creating a Very Basic Application Bundle / Package

I don't know anything about XCode or AppleScript, other than that they exist, so I'm coming at this with only conceptual knowledge of how applications on OS-X work. Nonetheless, I have a goal that I feel should be really easy to accomplish, I just don't know where to begin.
What I have is an html file with an embedded flash project that also references some outside files, such as pdfs for printing. This was designed to live on the web, but in reality it will be shipped out on a CD. Right now, if you insert the cd, you see the file contents (the above mentioned HTML file, as well as two folders containing the flash files and the pdfs that are embedded in or linked out from the html file).
This isn't very elegant, and doesn't accomplish the "app" feel I'm shooting for. What I'm wondering is: is there a way to create an application package that has the html file and content folders tucked inside of it, so that when a user clicks on the application package, the html file is automatically launched? What resources might you point me to in order to learn how to do this in a relatively short amount of time? (I'm not even positive if I'm using the correct terminology to search for solutions... is it an application package or an application bundle?)
Now for the limitations:
These files were generated on a Windows machine by an eLearning tool ("Articulate Presenter") and therefore really can't be fiddled with much. I can't open any of the flash files and change the directory paths for the resource files the main presentation needs. I'm fairly confident the presentation just refers to the folder the html file is in as its root, so if the file structure could stay relatively intact once all the files move inside this "bundle," I think everything will still work.
The Articulate Presenter folks aren't particularly helpful in solving Mac compatibility issues, so I thought I'd pose my question here. If I'm not being clear, I am happy to add additional details. Thanks very much for your patience with, and willingness to offer advice to, a complete newbie.
Cheers!

It's even easier than you think.
Open AppleScript Editor.
Type in the following code:
set htmlFile to (POSIX path of (path to me)) & "Contents/Resources/index.html"
set openCommand to "open " & quoted form of htmlFile
do shell script openCommand
Then do File > Save, and use 'Application' as the file format.
Then the "Bundle Contents" button on the toolbar will be enabled. Click it to open up the drawer.
Drag your HTML content and resources into the drawer.
Do File > Save again. Ta-da, you have your web-content packaged as an application.
This assumes that the top-level has a file named index.html. If not, modify to suit.

Question about creating and updating new columns in a table

Hi, I have a couple of questions that would love some answers to
Please bear in min that questions relate to datawarehouse / Just large tables with say about 50 million records
1) How do you create new columns in a big table
2) how do you update the new columns
3) would you create an index on a column in a table with 200m rows when the only two possible values are stored in the column (e.g.Y, N) - give your resason
my aswers to these would be
1) simple alter table ...
2) simple update statements
3) No need to create an index
I might be wrong on these in the context of datawarehouse
cheers
css_jay99

If the number of Y vs. N is about 50/50, you only have to parse through 50% of the
overall amount of columns.Fnord. If the ratio of Y to N was 1:20 then the index would be useful for searching for values of Y only. Or if the column is nullable and the bulk of the entries were null then it might be useful. But a 50/50 split? FTS is much more effective.
So, it does depend on the data distribution, but in most cases such an index would never be used (or should never be used).

Question about creating an alert title pop-up

Acrobat Pro 7, FrameMaker 7.2
I am trying to create some pop-ups in the PDF using the Frame maker: "alerttitle Help:"
The issue is that in the PDF, the alert displays as an empty page (kind of like an Acrobat sticky note). What are my options for replacing the icon with something of my choosing? I'd like a much smaller icon, like maybe a question mark.

No way to control the note's properties, other than doing it manually in Acrobat (and the icon size cannot be controlled).
In FrameMaker, you may use the alert marker instead of alertitle, since the built-in FM->Acrobat conversion does not deal with the title anyway (it will only be placed in the the note's content).
[With the FrameMaker-to-Acrobat TimeSavers add-on, you can use the ~note hypertext marker and control the note icon, title, color, location and open state; see http://www.microtype.com/ImprovePDF09.html for examples ]

Question about Creating DataSources for FlatFile Data Acquisition

Hello eveyone,
I am trying to create flatfile datasources. I've been checking out the existing ds in my dev system and there are some infrastructure here that have loaded data in them, all via their won flatfile DS. I've been looking at the DS and am trying to figure out logic in which they are defined. I saw that most of the fields are defined in CHAR even if they pertain to fields like quantity, Amount and so on... They are also in the Internal format. Yet they have been successfully loaded...
My question is: what are the rules of thumb in defining the DS? How do i go about in mapping the fields to objects in the system? Can anyone please give me the step-by-step scenario as to how to do this please?
Many thanks,
Philips

Hi Philip,
Pls. try the following steps ..may be helpful.
1. when ever you want to create a flat file structure..keep in mind that, what are
    fields data available in your file. second thing is you need to know the IO of
    the info provider in which you are uploading.
2. simply create your own DS with PC File, and other hand open up your infprovider, and keep on check with your flat file what is the sequence of the data
fields and what are they corresponds to in the cube/ODS
3. As your flat file sequence, keep on identify the related IO of your provider and
copy it individual and paste it in your infosouce one by one as sequence of your
flat file..
4. No need to think of what type of data it is and how it is..
5. simply copy all your correponding IO (what ever of their type) even including
    some of the ref. IO.
6. And finally save and activate your DS creation.
I hope it would help in creating your own Flat File DS.
Need further info revert...
Cheers,
Thanks=Points.

Question about creating child domains "before" parent

Ok, this is most probably a noob question.
My company (A.com), has a DNS zone in a linux server with records pointing to different web pages, example: radio.a.com, www.a.com, webmail.a.com, etc..
For a specific service, I need an Active directory domain called: daas.A.com
Thing is, I don't have an AD domain A.com in place. So my question is:
Do I need to create an AD domain for A.com before creating the one that I need?
If I don't, and I just create the daas.A.com as a new forest, will I be able to add an A.com domain in the future as parent?
As per DNS records in the linux box, I guess I would only need a NS pointing to the DNS of the new domain, and an A record resolving that to an IP. or Something like that..
Thanks!

Yes, even if initially it is an empty root, otherwise the child domain will become the forest root.
So the A.com domain will need to duplicate those records that Linux currently hosts otherwise AD clients will start having name resolution issues. If you just need to stand up AD for one application then I would go ahead and standup the empty root, add the
child domain, install the service that needs AD and go from there. That is if you think at some point you will use the a.com domain.
Active Directory will actually create 2 zones (A.com and _msdcs.A.com)
Daas.A.com will have 1 dns zone daas.a.com and will also utilize the _msdcs.a.com
So I have been in environments which have had both a windows dns server and a Linux dns server, eventually after enough duplication of records in both areas and the pain points that caused, we have retired the Linux dns servers and just used the AD DNS servers
(with the exception of DNS servers that were internet facing which we kept on Linux) Primarily the ease of administration and the fact that AD and DNS are tightly coupled.

Beginners question about creating first database and tables

Hi all,
i recently have installed 10g express edition, because i want to transform my php-script from mysql to oracle database. (due to the fact that mysql is "not allowed sofware" at the company i work for).
it is a quit small script, just a shift-report system, build because of frustration about an used shift report system based on excel sheets. Company likes it, but IT-department rejected it, because it is myssql. They do own a lot of oracle servers, so they set up a database for me, got a username and password.(Tnsnames entry). The rest i have to do by myself, no further support from IT department.
I have made 2 simple php functions to connect to database:
// for connection home server:
function conn()
     $user = 'user';
     $password = 'password';
     $conn = oci_connect($user, $password, 'localhost/XE');
     return $conn;
// for connection at work:
function Xconn()
     $db = '(DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = xxx.eu.xxx.com)(PORT = 1521))
    (CONNECT_DATA = (SID = NVGPP)))';
     $user = 'xxxxxxxx';
     $password = 'xxxxxxx';
     $conn = oci_connect($user, $password, $db);
     return $conn;
}I just add or remove X character before function name, for use at home or at work.
both do work fine.
First thing i wanted to do, is to create my database and tables.

Please, help is really appreciated by me.

Translating from mysql to Oracle will need a bit of fixups for the DDL, once an oracle instance is created, set up and running, you won't create a database but you will have a database user or users that create/own a collection of tables, indexes, functions, procedures, etc.
It will take a bit of pouring through the oracle documentation to get those table create statements to work, i.e. the engine=, charset=, auto_increment items won't succeed, datatypes need adjustments, the tic marks around the entity names aren't necessary, quite a few other items from the mysql data definition language don't have an oracle equivalent.
