Database link in Apex

Hi,
I have a problem with Database link in my application.
Is their any way to Drop the Database link in APEX.
Thank You,
Edited by: Jahnavi on Nov 2, 2009 1:09 PM

Jahnavi:Does this query creates a new connection every time I press the button? It depends on whether the local connection that handles your page request already has a connection open to the remote database. If a remote connection is open then the connection is re-used.
Why would you want to terminate the database link ?

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.

Database links in APEX - Inconsistent

I have just set up a database link to our main Oracle DB from an APEX DB using the object browser in APEX
The link works fine for retrieving data in some circumstances, a report is displayed with no problems and dynamic lookup lists work fine.
However when I create a form and include an "Automated Row Fetch" there is a "PLSQL invalid error". My guess is there is some problem with privileges, I have little experience with this so was hoping for some help
Regards
- Sol

Sol,
I believe you can create a local view on the remote table and build the form on that view. See this and similar posts for hints: Use a database link in an Automated Row Fetch process? .

Forgot how to call a database link in Apex... @linkname not working for me

Don't have access to my old apps and I can't remember how to call fields from a database link now...
when i try
select "TABLE"."DATE" as "Date"
from "TABLE" "TABLE" @LINKNAME
I get ORA-00933: SQL command not properly ended
Tried CHRISD which is the name of the link, then tried CHRISD.REGRESS.RDBMS.DEV.US.ORACLE.COM which is the entire name.
Neither one looks right to me but I can't remember the correct syntax for the link name... I remember putting something about userlink in there somewhere but nothing I can think of works.
anyone?

select ename from emp@dblink
...lose the double quotes.

Hi,
i don't have a solution for your problem but i want to share with you my research in using Database Links with XE/Apex.
I have done it a in a lot of projects and in most of all cases it shows a strange behavior when using Database Links via Apex. As far as i know SQL-Request in Apex are executed via the DBMS_SQL-Package. And that seems to be source for all errors and strange behaviors you get.
If you post a SQL-Request directly from your XE, everything's fine. If you do the same from APEX, sometimes it is very slow and sometimes it fails.
So, my approach to this issue is to work with Materialized Views. Your can create MV's on your XE to reference your remote tables and even schedule refreshes. In Apex, you only work with these MV's instead of the remote tables. And everything's going to be fine!
Hope this helps!

I have a problem when update tables with a database link (APEX)

Hi, I search answers for my problem and I not found a solution. My problem start when I open page with database link statement in APEX. I drop tables and execute this for update the tables in APEX.
EXECUTE IMMEDIATE 'CREATE TABLE XXXXXXX
AS
SELECT A1,A2,A3
FROM AAA@BBB';
I use Mozilla Firefox and isn't always updated the tables because it shows dialog for downloading file "f". I rename the file to txt and I see the text "IBMPC/WIN_NT-8.1.0"...
In the explorer always show a window only the text "IBMPC/WIN_NT-8.1.0"...
What is the solution for my problem? I need update this tables.
Thanks. John.

It's easy. It doesn't work a database link, on apex, with a pl/sql code or store procedure.
I saw that many people had the same problem but I don't see a solution.
As I put up, I want to remove my tables on APEX and copy the table of my Oracle database with the update dates.
The posts are from the same problem as my English is very bad, it got to help explain the problem.
I have a page with a pl/sql code. This code in Oracle is correctly.
For example, with this code I update the table PRUEBAS with the data of TABLEX.
BEGIN
BEGIN
EXECUTE IMMEDIATE 'DROP TABLE "PRUEBAS"';
EXCEPTION WHEN OTHERS THEN NULL;
END;
EXECUTE IMMEDIATE 'CREATE TABLE "PRUEBAS"
AS
SELECT AAA,
BBB,
CCC
FROM TABLEX';
END;
But, in this code, I have the problem.
BEGIN
BEGIN
EXECUTE IMMEDIATE 'DROP TABLE "PRUEBAS"';
EXCEPTION WHEN OTHERS THEN NULL;
END;
EXECUTE IMMEDIATE 'CREATE TABLE "PRUEBAS"
AS
SELECT AAA,
BBB,
CCC
FROM TABLEX@DB_LINK';
END;
I sometimes get an error. Sometimes it works fine, but half of the tries Apex returns "IBMPC/WIN_NT-8.1.0" in the browser and I am not using an IBM PC or Win NT...
And i read that In the alert_xe.log file there are a error of core dump... ... :S or that the application return corrupt headers.... Is a problem of versions?
I used a synonym and I have the same problem.
Even if I run the code on SQL COMMANDS (SQL WORKSHOP) it shows dialog for downloading file "f". I rename the file to txt and I see the text "IBMPC/WIN_NT-8.1.0"...
The problem is in Mozilla Firefox and in IE.
I have the OracleXE 10g (Application Express 3.0.1.00.08).
And the question is.. ... ... ... ... What is the solution? :)
Thanks.
John.

To create database link to connect to remote database

Hi all
I am using 10g with apex4.
My apex application is running on our server.
I need to connect to a remote server to get data from there.for that i need to create a database link from apex.
When i tried to create a database link from apex sql commands window it is showing insufficient privilages.
So i created one database link from back end but it is not accessible from apex...
can some one help me in this...
its urgent.....
thanks in advance

Hi,
You need create database link to schema that is assigned to your workspace (application parsing schema)
Schema need have CREATE DATABASE LINK system privilege.

Jari

Apex and remote database links.... Good idea or bad?

We would like to have one single Apex installation that would be used to develop many applications against many remote databases.
Database links would seem to be the obvious mechanism to achieve this goal, but we have had many issues with db links.
Also, our research indicates this might not be a good idea for various reasons.
Any opinions or experiences around this topic would be greatly appreciated.

we have had many issues with db links. In that case it's a bad idea.
It's not really an Apex question. If you can't get db links to work, it's a database issue. If it's performance over the db link, again it's a database issue (assuming modern networks aren't the bottleneck here). Remote views (instead of selecting from remote tables) often increase performance.
If the applications don't have to share data over the db links, you can set up one master application and several sub-applications on the different databases. The master is used to log in once. See:
http://www.oracle.com/technetwork/issue-archive/2009/09-may/o39security-101079.html

Apex and database links

Hi,
How does Apex perform using database links. We are currently on version 3.1.1.00.09 of Applicatiion Express and have all of our data in one database. We will soon be upgrading our environment to Oracle Database Appliance. We are thinking about splitting our staging area out of our existing database. We use Apex for our dashboard reporting. We are in hopes to upgrade to latest version of Apex. If we split our database up we will have to use database links to access data. How does Apex perform using database links. Will our Interactive reports work? Will performance degrade? Wanted to know your thoughts on that.
Pam

Having used such a model for several years, I'd confirm that it is possilble to make it work, however it may not be optimal, performance-wise (depending on your data model).
Typically speaking, if you are just querying your external database "straight" (i.e. where all of the tables being queried are on the remote DB), you shouldn't notice a significant degradation in performance. The problems can come in when you either include "local" tables in your queries (in which case you need to decide which site should be 'driving') or where DML is involved (in which case the driving site defaults to the local DB) - your execution plans can change quite significantly and often for the worse.
I have tried a few strategies to mitigate against this, including converting some DML statements to be based on pipelined table functions instead of views, creating local Materialized Views of commonly accessed data (usually aggregated in some manner), or caching result sets (i.e. using the built-in apex caching function) for something more flexible but ultimately it'd be easier if everything was sitting on the same DB.

How to connect APEX with MYSQL via Apex's Database link

How do i connect APEX with MYSQL via Apex's Database link? The OBE doesn't go into specific detail about how to link the two.
can someone please elaborate on what these are and where i can find them in mysql:
Database Link Name
Connect To Schema
Password
Remote Hostname or IP
Remote Host Port
SID or Service Name
I need to link to mysql database so I can set up a 3D pie chart in apex

Hi jononioo
A database link is a device for connecting between Oracle database instances only. Oracle does have a method for connecting to other database systems (Transparent Gateway) but this is restricted to other commercial databases and I don't believe there is a gateway for Mysql. (I could be wrong)
I don't know Mysql but maybe there is some way to push data to the Oracle instance. Other than that, is there any reason why the data has to reside in the Mysql database?

How to create a database link between an 8i (apps) database and APEX

Want to link my Oracle APPS databse on 8i with Oracle XE and APEX. Any idea how to achieve this ?

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;

Interactive report performance problem over database link - Oracle Gateway

Hello all;
This is regarding a thread Interactive report performance problem over database link that was posted by Samo.
The issue that I am facing is when I use Oracle function like (apex_item.check_box) the query slow down by 45 seconds.
query like this: (due to sensitivity issue, I can not disclose real table name)
SELECT apex_item.checkbox(1,b.col3)
, a.col1
, a.col2
FROM table_one a
, table_two b
WHERE a.col3 = 12345
AND a.col4 = 100
AND b.col5 = a.col5
table_one and table_two are remote tables (non-oracle) which are connected using Oracle Gateway.
Now if I run above queries without apex_item.checkbox function the query return or response is less than a second but if I have apex_item.checkbox then the query run more than 30 seconds. I have resolved the issues by creating a collection but it’s not a good practice.
I would like to get ideas from people how to resolve or speed-up the query?
Any idea how to use sub-factoring for the above scenario? Or others method (creating view or materialized view are not an option).
Thank you.
Shaun S.

Hi Shaun
Okay, I have a million questions (could you tell me if both tables are from the same remote source, it looks like they're possibly not?), but let's just try some things first.
By now you should understand the idea of what I termed 'sub-factoring' in a previous post. This is to do with using the WITH blah AS (SELECT... syntax. Now in most circumstances this 'materialises' the results of the inner select statement. This means that we 'get' the results then do something with them afterwards. It's a handy trick when dealing with remote sites as sometimes you want the remote database to do the work. The reason that I ask you to use the MATERIALIZE hint for testing is just to force this, in 99.99% of cases this can be removed later. Using the WITH statement is also handled differently to inline view like SELECT * FROM (SELECT... but the same result can be mimicked with a NO_MERGE hint.
Looking at your case I would be interested to see what the explain plan and results would be for something like the following two statements (sorry - you're going have to check them, it's late!)
WITH a AS
(SELECT /*+ MATERIALIZE */ *
FROM table_one),
b AS
(SELECT /*+ MATERIALIZE */ *
FROM table_two),
sourceqry AS
(SELECT b.col3 x
       , a.col1 y
       , a.col2 z
FROM table_one a
    , table_two b
WHERE a.col3 = 12345
AND   a.col4 = 100
AND   b.col5 = a.col5)
SELECT apex_item.checkbox(1,x), y , z
FROM sourceqry
WITH a AS
(SELECT /*+ MATERIALIZE */ *
FROM table_one),
b AS
(SELECT /*+ MATERIALIZE */ *
FROM table_two)
SELECT apex_item.checkbox(1,x), y , z
FROM table_one a
    , table_two b
WHERE a.col3 = 12345
AND   a.col4 = 100
AND   b.col5 = a.col5If the remote tables are at the same site, then you should have the same results. If they aren't you should get the same results but different to the original query.
We aren't being told the real cardinality of the inners select here so the explain plan is distorted (this is normal for queries on remote and especially non-oracle sites). This hinders tuning normally but I don't think this is your problem at all. How many distinct values do you normally get of the column aliased 'x' and how many rows are normally returned in total? Also how are you testing response times, in APEX, SQL Developer, Toad SQLplus etc?
Sorry for all the questions but it helps to answer the question, if I can.
Cheers
Ben

Advise on DB links in APEX

Hi,
I have installed apex on my test system in the same database where my original data resides and application is working fine.
Now for production my org dont want to install apex on the same db(server 1). They want me to install apex on separate db server (server 2) and refer it(server 1) using Database links from server2.
They dont want me to build any table related to apex or application logic in the original database(server1).
please advise ,What is the best way to do that...
Do i need to recreate the whole application using db links.
or is there any way to redirect to original db server(server1) from application server(server2).
Please help.

Report over database link error

Good morning all.
I have a database link LINKA from USERA on LOCALSERVER to USERB on REMOTESERVER.
(create database link LINKA connect to USERB identified by mypassword using validtns)
In USERC on REMOTESERVER I have a TABLEX, with grant all on TABLEX to USERB on REMOTESERVER.
In USERB on REMOTESERVER I have a view TABLEXV, select * from USERC.TABLEX
From USERA on LOCALSERVER I can select * from TABLEXV@LINKA. In fact I can insert/update/delete tablexv from USERA.
I also have a view TABLEXV on USERA, select * from TABLEXV@LINKA. I can also select/insert/update/delete from USERA.TABLEXV.
So far so good - all working as expected.
Then, my APEX app on LOCALSERVER, interactive report, parsing schema USERA, querying TABLEXV, I get the following:
when "Exclude Link Column", I get the error "The requested URL /pls/apex/f was not found on server.
when "Link to Single Row View", report displays correctly.
when "Link to Custom Target", I get the error "The requested URL /pls/apex/f was not found on server.
When I run the select * from TABLEXV as a regular report (i.e. not interactive), I also get the error.
So the only time I get the report displayed correctly is using IR and "Link to Single Row View".
However, clicking on the link (for Single Row View) I get "The requested URL /pls/apex/wwv_flow.show was not found on this server.".
To summarize:
- accessing table via view over database link
- works outside of apex without issue
- inside only works when Link to Single Row View set
- But clicking on link fails
I could live with just having the Link to Singe Row View option if I could disable displaying of the icon so that the user cant click on it.
APEX 3.2.00.27
EE Database - 10.2.0.3 (yes I know out of support)
Remote EE Database - 10.2.0.5
Real object names replaced to protect the innocent!
Anyone got any clues?
I have used remote tables many times in my APEX applications and never had this issue.

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,
Pam

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
