How do you create a database link in Forms9i

I am writting and application that is to connect to multiple databases and do given task, but the triggers I assign to items only work in the database that you connect to for forms to run.
How do you create a database link in Forms9i?
Thank you in advance for your reply.

It seems like you will have to have database links set up in all your databases to point to all other remote databases and have a common global naming scheme for all your objects so that no matter what database you log into you will have access to all objects in the universe.

How do you close a database link in Apex?

How do you close a database link in Apex that is referenced in an interactive report on Page 1? I want to make sure the database link is closed before a user navigates to another page in the Apex application.
Lets assume the database link is referenced in the region source for Page 1 as follows:
Page 1 - Employee Listing
Region Source:
select ename, job, hiredate
from scott.emp@link1
Any suggestions are appreciated.
Ms. H

John,
I figured out how to eliminate the ORA-02020 and ORA-02081 errors. The solution is reference below:
1. Create an interactive report in a page.
2. Add the SQL statement in the region source as listed below:
SELECT ENAME, JOB, HIREDATE
FROM SCOTT.EMP@DBLINK
WHERE (UPPER(ENAME) LIKE '%' || UPPER(:P1_TEXT_SEARCH)||'%')
Conditional Display
     Condition Type:
PL/SQL Expression
     Expression 1
     :P1_TEXT_SEARCH IS NOT NULL
3. Add a search button and text search field as items on the page.
4. Create a process in the page to check the cursor and catch an exception as listed below:
     Name: CHECK_CURSOR
     Sequence: 30
     Point: On Submit - After Computations and Validations
     Type: PL/SQL Anonymous Block
     PL/SQL Process:
     FOR C1 IN (SELECT ENAME, JOB, HIREDATE
     FROM SCOTT.EMP@DBLINK
WHERE (UPPER(ENAME) LIKE '%' || UPPER(:P1_TEXT_SEARCH)||'%'))
     LOOP
     IF C1.ENAME IS NOT NULL
          THEN
          HTP.P('Employee Name: '||C1.ENAME||' ');
          END IF;
     END LOOP;
     EXCEPTION
          WHEN NO_DATA_FOUND
          THEN
          APEX_APPLICATION.G_PRINT_SUCCESS_MESSAGE := 'No Data Found Error';
          WHEN OTHERS THEN
          APEX_APPLICATION.G_PRINT_SUCCESS_MESSAGE := 'Unexpected Error';
Conditional Processing
When Button Pressed (Process After Submit When This Button is Pressed)
     P1_SEARCH_DATA
5. Create a process in the page to close the database link as listed below:
     Name: CLOSE_DBLINK
     Sequence: 40
     Point: On Submit - After Computations and Validations
     Type: PL/SQL Anonymous Block
     PL/SQL Process:
     COMMIT;
     EXECUTE IMMEDIATE 'ALTER SESSION CLOSE DATABASE LINK DBLINK';
Conditional Processing
When Button Pressed (Process After Submit When This Button is Pressed)
     P1_SEARCH_DATA
6. Apply changes, run the page, and conduct a test.
I hope this solution is helpful to others.

How do you create a text link to jump to a row in numbers

Short: How do I create some simple link from Row 1 Cell 1 showing December, to jump my screen down to row 300 for example?
I want to do this because I use numbers for a 365 days per row long spreadsheet, and collumn A B C D E are staff names, it's alike a daily booking calendar for employees for me to see availability.
I have made the top header row of staff names frozen, so when I stroll down I see the staff names above each collumn, useful. I have also added a row under this and want to write each month, e.g. Jan, Feb, Mar and turn those to links, taking me directly to the row in the spreasheet. How on earth does one do this?
I have searched: internal link, simple link to a row, internal shortcut, internal link and others, can not find it in this forum, google or the help.
Thanks
Andy

This script isn't based on a Numbers 09 script so I don't know if it works the same way, but it seems to work ok in Numbers 3.5.
The dates (Jan 1, Jan 2... Dec 31) must be formatted as text, NOT as date and time.
For ease of reference the table is called Holiday Planner. The script must be updated if this is changed.
The top of the table looks like this:
This is the script:
set esc_key to 53
tell application "Numbers"
activate
set the_month to (choose from list {"Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"} ¬
with prompt "Which month do you want to jump to?")
if the result is false then return
set the_month to the_month as string
tell document 1
tell active sheet
tell table "Holiday Planner"
set the_row to item 1 of (every row where ((value of cell 1) begins with the_month))
set selection range to the_row
tell application "System Events"
key code esc_key
end tell
set selection range to the_row
end tell
end tell
end tell
end tell
One cosmetic problem is that when you jump "onwards" in the calendar as opposed to "backwards", the first row of the month appears at the bottom of the window rather than at the top. I'm not sure there's any way of fixing that.
Save the script in your ~/Library/Scripts/Numbers/ folder and then you can run it from the Numbers script menu:
Hope it's useful.

How can you SELECT via Database Link CLOB data using Application Express?

Customer Issue:
Developer using Oracle's Application Express 3.1. The Developer is trying to SELECT a CLOB datatype column from a remote (10.2.0.3) database, via a database link on her 10.2.0.4 based client Application. The Developer wants to be able to select CLOB data from the remote database which has limitation that she can't make any changes to the remote database.
Developer's Comments:
I do a select and get the error. Getting error ORA-22992: cannot use LOB locators selected from remote tables. So she feels she can't use dbms_lob.substr in this configuration I can do a "select into" but that is for one value. I am trying to run a select statement for a report that brings back more than one row. I do not have permission to change anything on the remote database. I want to access the remote database and multiple tables.
This is not something I work with, would greatly appreciate help or ideas. Is this a limitation of the 3.1; or does she just not have this set up correctly; or should she be using a Collection (if yes, please share example)
Thanks very much,
Pam

Hello???
Would really appreciate an answer.
Thanks,

This may not be a perfect solution for you but it worked for my situation.
I wanted to grab some data from Grid Control's MGMT$JOB_STEP_HISTORY table but I couldnt' create an Interactive Report due to the existance of a CLOB column. I cheated this by creating a view on the GC DB, grabbing the first 4000 characters and turning it into a varchar2 column:
create view test_job_step_history as
select job_Name, target_name, status, start_time, end_time, to_char(substr(output,1,4000)) output
from MGMT$JOB_STEP_HISTORY where trunc(end_time) > trunc(sysdate)-90
In an APEX Interactive Report:
select * from test_job_step_history@GCDB
Granted, the output looks aweful right now but I am only looking for a very particular output (failed, denied, ORA-, RMAN-, etc) so the formatting isn't the most important thing to me right now.
If anyone can improve -- and I'm sure you can -- on this I'd love to hear about it.
Thanks,
Rich

How do you create a download link?

I want to create a hyperlink so that visitors of my website can download certain files (large pictures in this case). I publish my website by copying the index.html and website folder with the "transit" program to the server.
the only working method that I found until now is the following:
I put the files in the folder of a hidden webside, called pressefotos in this case, create the hyperlinks from smaller pictures to the files, save the website into a folder. After saving the files that I manually put in the "pressefotos" folder are gone, so I put them there again and copy the whole website folder to the server.
ehm-
can this be achieved in a simpler way?

the actual problem was that hyperlinks don't work when the file name contains umlauts.
By the way: how do you edit a post?

How do you create a database so that the PDF forms will populate the database as they are submitted?

I am trying to create PDF forms that will be filled out by multiple members of an organization. I would like them to be submitted electronically and then populate a database so that the data does not need to be reentered into a database.
I generally use Microsoft access but certainly know how to use comma separated values (CSV) or Microsoft Excel.
I currently utilize Acrobat Pro X.

Thanks for the info obviously I will need to watch the videos/tutorials on distributing and tracking documents.

How to create a database link on an ms acces data source

Hello every body
Is it possible to create a database link on an MS access data source under
oracle 10 g and Apex ?
If yes how to do it ?
Thanks in advace

I don't know what Apex is!!! But try to follow these instructions.
It works for Oracle 9i.
As far as I know, you are supposed to have installed other than ORACLE Client to complete these instructions.
1. Control Panel / Administrative Tools / Data Sources (ODBC)
Folder: System DSN /
click add
Choose : Microsoft Access Driver
Data Source Name : my_test
Description : any_description_you_want
click Database/Select... : full pathname for <your_file.mdb>
click OK
Click OK
2. Goto OH\hs\admin:
2.1) Create a copy of "inithsodbc.ora" file giving it this name:
initmy_test.ora
2.2) Edit "initmy_test.ora" and change as below.
# HS init parameters
HS_FDS_CONNECT_INFO = my_test
HS_FDS_TRACE_LEVEL = OFF
3. Add this entry to listener ( Don't forget to stop/start the listener )
(SID_DESC =
(SID_NAME = my_teste)
(ORACLE_HOME = <Path to OH> ) ### Ex: D:\ORANT901
(PROGRAM = hsolesql)
4. Now you need to add entries to point to the HS in the tnsnames.ora :
access =
(DESCRIPTION=
(ADDRESS=(PROTOCOL=tcp)(HOST=<your_host>)(PORT=1521))
(CONNECT_DATA=(SID=my_test))
(HS=my_test)
5. Now you need to go into the database and create the database link:
CREATE PUBLIC DATABASE LINK "ACCESS_DB" USING 'access';
6. select * from your_table@ACCESS_DB;

where i am making mistake?
i gave the linkname as my remote database name.
am i have to make any entry in the tnsnames.ora?
thanks & regards

You have to remember that when you access a dblink, the database where the link is defined is acting as a client to the database to which the link points ... exactly the same as if you you were using sqlplus on the machine hosting the db where the link is defined. In other words, given:
Host 'Host-src', with database 'db-src', with a dblink 'lk_target'
Host 'host-trgt', with database 'db-trgt'
When you connect to db-src and access lk-target, db-src is now acting as a client to db-trgt. Exactly as if you had opened sqlplus on host-src and connected directly to db-trgt. So, given the above scenario
host-src$> sqlplus scott/tiger@db-src
sql> select * from emp@lk_target;when you execute that SELECT to the link, the same tns considerations are in effect as if you had
host-src$> sqlplus scott/tiger@db-trgtThe same tnsnames.ora entry, on the source machine, is required for both.

How to create a database link ?

i want to create a database link.please give mesteps

There is a chapter in the DBA Administration manual for versions 8.1, 9.2, and 10g on this topic which provide all the information you need.
You will need to choose the type of database link: global, current user, or imbedded user and if you need a public or private link.
Basically all you do is create a tnsnames.ora entry for the remote db and then create a database link (See SQL manual entry CREATE DATABASE LINK) that references the tnsnames.ora entry.
The manuals or the entire manual set can be downloaded from technet.

Deploying a mapping creates a database link

I have one mapping where everytime I deployed a mapping it always creates a database link. How do I remove this and how did this happen?

Is the problem that you expect a local reference like SCOTT.EMP rather than SCOTT.EMP@DBLINK? Check the source and target locations for the tables in your mapping, check that the locations are defined identical in the host:port:service name? Did you define them with H:P:S? May be one has localhost the other a machine name or something.
Cheers
David
