Hi, need ur help again,
i have create a database link using this script:

IDENTIFIED BY "123456" USING
'(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=161.142.72.58)(PORT=1521)))(CONNECT_DATA=(SID=DB001)(SERVER=DEDICATED)))'

Symptoms
Describe on a Synonym which is based on a database link may issue error:
ORA-2019 connection description for remote database not found
Select from the synonym works successfully.
Cause
Based on the Bug 3071468 this issue happens when the local
and the remote database have different domain name in the GLOBAL_NAME.
For example if:
select * from global_name;
gives from local database:
PROD.UK.ORACLE.COM
and the remote database has:
TEST.US.ORACLE.COM
then we have different domains for the global_name.
This does not reproduce when the domain is the same for both global_names.
Fix
This issue is fixed in 10.1.0.2.
For previous versions we have the following 2 workarounds:
1. Use View in the place of the synonym. This works.
2. Alter one of the databases global_name , so that the 2 global_names to have the same domain.
For example in the above example chenge the TEST database as:
sql> alter database rename global_name to test.uk.oracle.com;
Then you would have to drop and recreate the database link.

Drop database link & ORA-02082 Error

Hello,
I have created db link. Now, I would like to DROP it but I got "ORA-02082 a loopback database link must have a connection qualifier".
I have tried every possible combination but without success.
Thanks for help
sasa

Hello Barbara,
I agree with you that if db link exist I should be able to drop it. If you look into my first reply there is complete select from user_db_links. Select from dba_db_links are the same because I haven't any others db links. I try to drop the db link as owner or as sys. I do not need to think about drop with name "qwer.cscargo.cz" because is wrong (our inner domain is "in.cscargo.cz"). The only difference among others db links is that qwer have "current_user".
DB_LINK USERNAME HOST
CARGODB.IN.CSCARGO.CZ CARGO_ADM cargodb
LMDB.IN.CSCARGO.CZ CARGO_ADM lmdb
QWER.IN.CSCARGO.CZ CURRENT_USER speisdb
SPEISDB.IN.CSCARGO.CZ CARGO_ADM speisdb_rac
There could be one problem. I created the db link when my db have name "speisdb". I rename my db (using rman - duplicate db) to "speisdev". Could be this source of problems?
Here is output of your drop script:
drop database link qwer

Cannot drop public database link

Hi all.
Just trying to drop some old database links and getting the following:
SQL> select * from dba_db_links where host = 'V638';
OWNER DB_LINK USERNAME HOST CREATED

SQL> drop public database link V638;
drop public database link V638
ERROR at line 1:
ORA-02024: database link not found
There was another db link in there called V638.WORLD and when I issued
drop public database link v638 it removed that one with no errors...
Any way I can get rid of this other one?

ORA-02020 too many database links

Hello,
I'm getting the ORA-02020 too many database links error in my Apex application. This error occurs when I run an interactive report in a page. There are 21 pages and 7 database links in the application. Each page has one interactive report that references one database link in the region source.
The database links are referenced in each page as follows: database link1 (page 1); database link2 (pages 2 and 3); database link3 (pages 4-7), database link4 (pages 8-15); database link5 (pages 16-18); database link6 (pages 19); and database link7 (pages 20-21). Each database link is referenced to separate schemas in one remote Oracle database.
I tried to eliminate the error by setting the open_links and open_links_per_instance parameters in the init.ora file of the remote and XE databases to 100 then restarted the both databases. This solution did not work. I created separate Application Processes from the Shared Components to close each database link by implementing the following:
Click on Shared Components> Logic > Application Processes > Create >
Name: CLOSE_LINK1
Sequence: 1
Point: On Load: Before Header (page template header)
Type: PL/SQL Anonymous Block
Process Text: execute immediate 'ALTER SESSION CLOSE DATABASE LINK LINK1';
Error Message: Database Link Error
When I run the application now, the ORA-02081: database link is not open error appears.
Please help anyone! I know someone has experienced these same errors.
Thanks,
Ms. H

Joel,
Thank you for your quick response. For clarification purposes, could you provide samples for 1) issuing the CLOSE DATABASE LINK and catching the exception; and 2) querying from V$DBLINK prior to issuing the CLOSE DATABASE LINK from the Shared Components > Logic > Application Processes?
Lets assume the following query with a database link in the region source is referenced for Page 1.
Page 1 - Employee Listing
Region Source:
select ename, job, hiredate
from scott.emp@link1
Lets assume the following Application Processes from the Shared Components is referenced to close the database link:
Click on Shared Components> Logic > Application Processes > Create >
Name: CLOSE_LINK1
Sequence: 1
Point: On Load: Before Header (page template header)
Type: PL/SQL Anonymous Block
Process Text: execute immediate 'ALTER SESSION CLOSE DATABASE LINK LINK1';
Error Message: Database Link Error
My thoughts are to do the following:
1. Log in SQL*Plus as SYS
SQL> grant select to v_$dblink to scott;
2. In Apex, goto Shared Components> Logic > Application Processes and add the following queries in the Process Text:
Name: CLOSE_LINK1
Sequence: 1
Process Text:
select db_link from v$dblink;
execute immediate 'ALTER SESSION CLOSE DATABASE LINK LINK1';
3. Catch the exception???
Your assistance is greatly appreciated. :8}

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!

Strange problem with Database LInk

Hi Everyone,
I have strange problem with Database Link in Oracle 11g Express Edition;
There are two computers: computer-server and computer-client. Tnsnames.ora are the same on both computers ie.
CT =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = krzysztof)(PORT = 1521))
(CONNECT_DATA = (SERVICE_NAME = XE)
I created database link :
Create database link zdalny
Connect to <user_id> identified by <password>
using ‘CT’;
Client can’t connect with server when I am using above command. But when I change “using” for using ‘krzysztof:1521’ or using ‘krzysztof’ or using ‘server IP:1521’ – everything is ok.
Why I am asking. Because in all materials which I am reading about Oracle command with using ‘CT’ should be working correct. But there is not. Do you know, why?
Thanks in advance and apologize for my English.

PS. I tried with using 'XE' - not working.Assuming that is the correct tnsnames, of course XE is not working. You don't have a tnsnames entry for 'XE'.
You need to be aware that when using a dblink, the client is the db in which the link is defined, not the desktop from which you connect to that database.
I think you need to start here:
http://edstevensdba.wordpress.com/2011/02/26/ora-12154tns-03505/
http://edstevensdba.wordpress.com/2011/02/09/sqlnet_overview/ (Help! I can’t connect to my database )
http://edstevensdba.wordpress.com/2011/02/16/sqlnet_client_cfg/ (Help! I can’t connect to my database (part duex) )
The fact that your client (db link) is a database doesn't change anything taught in the above.

Database link error when compiling forms 6.0 and forms 6i.

Dear sirs,
We have a database link between two databases of the same version oracle 8.0.5.
Recently we have upgraded one of our databases to version 9.2.0.1 (the database where the database link was originally created ) and now we are having problems when compiling forms that have PL/SQL blocks using the database link.
The error message received when compiling the form is the following:
ORA-02068: Following severe error from dbproduc.world
ORA-00600: Internal error code, arguments: [No conversion op],[],[],[],[],[],[],[]
The forms did not present this error before, it began when we made the upgrade.
Is this a FORMS 6.0 problem ?
Is this an ORACLE 8.0.5 problem ?
Is this an ORACLE 9.2.0.1 problem ?
Can you please give me some advice to solve this problem ?
Thanks in advance

As I see, when you use a non-oracle database the tables don`t appear, you must create the realation with the table manually, on the properties

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.

Error in database link(ORA-02063 and ORA-02391)

Hi
database link was working fine till this morning. now when i try to query using the database link, i get the following error
ORA-02391: exceeded simultaneous SESSIONS_PER_USER limit
ORA-02063: preceding line from RMSLIVE
It would beof great help if you can advise why this error is occuring.
many thanks.

The error stack is quite obvious.
Either, the profile, with which the database user on remote database is running, must be modified to allow more connections or investigate the session leak in the application talking over database links.

TNS-12666 error occures when using database link

When I am trying to use database link
defined in my database the following error occures:
TNS-12666 Dedicated server: outbound transport protocol different from inbound.
In documentation is stated to resolve such an error to
specify the same protocol in the SQL*Net connect string or alias for the outbound connection as that used for the inbound connection.
I have in tnsnames.ora defined network service name
by which I can connect to such a database by SQL*Plus
without any problems, why can I not do such a thing
via database link?
Thanks a lot for advise, ...

Could you change the following entry in your 'sqlnet.ora' file and try?
SQLNET.AUTHENTICATION_SERVICES = (NONE)

Error while creating materialized view which using database link

Helo!
I'm getting error "ORA-00942: table or view does not exist" when I want to create materialized view.
Details:
1. On destination database I create a database link:
CREATE DATABASE LINK SDATABASE
CONNECT TO MYUSER
IDENTIFIED BY MYUSERPASS
USING 'ORCL';
=> Command "SELECT * FROM TABLE1@SDATABASE" returns data normally!
2. On source database I create MATERIALIZED VIEW LOG:
CREATE MATERIALIZED VIEW LOG
ON TABLE1
WITH PRIMARY KEY
INCLUDING NEW VALUES;
3. Now, when I want to create MATERIALIZED VIEW on destination database:
CREATE MATERIALIZED VIEW TABLE1
REFRESH FAST
START WITH SYSDATE
NEXT SYSDATE + 1/1440
WITH PRIMARY KEY
AS SELECT * FROM TABLE1@SDATABASE;
...I get error "ORA-00942: table or view does not exist"!
How is that possible if command "SELECT * FROM TABLE1@SDATABASE" returns data normally?
Thanks,

Error using database link

Before creating the link, I went into my init.ora file and made sure the GLOBAL_NAMES entry was false.
I then created a database link using the following:
create public database link cindy_link
connect to system identified by syspswd
using 'PRECISEI';
My link was created, but when I attempt to use it, I get the error:
ORA-02085:database link CINDY_LINK.WORLD connects to PRECISEI.WORLD
Here is the entry from my tnsnames.ora file:
PRECISEI =
(DESCRIPTION =
(ADDRESS_LINK =
(ADDRESS =(PROTOCOL = TCP)(HOST = taurus)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = precisei.world)
Here is the entry from my listener.ora file:
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = precisei.world)
(ORACLE_HOME = E:|oracle\ora81)
(SID_NAME = precisei)
(I must admit to not having a full understanding of SID_NAME vs SERVICE_NAME.) I looked in dba_db_links, and my db_link is named CINDY_LINK.WORLD instead of CINDY_LINK.
Do I have a problem in one of my files?
I would really appreciate any help.
Thanks.

Well, I was facing the same problem but corrected it later on. Let me describe the solution is little detail.
You need to check few things before creating db link.
1) db_name and db_domain in init.ora file
2) global_name in listener.ora file
3) service name in tnsnames.ora file.
It seems to me that you have not specified the db_domain in init.ora file. And in that case, you need to follow these steps.
I am considering here that you have database A on server X and database B on server Y.
Go to the first server (server X).
set the global name in init.ora file by following
Global_name=true
db_domain=usa.com
Start and open the database.
connect as system user.
(if your oracle sid is orcl then)
svrmgr30>alter database rename global_name
to orcl.usa.com;
this will set the global_name as specified in init.ora file. Here, your SID is orcl and db_domain is usa.com so global_name will be orcl.usa.com.
svrmgr30>Select * from global_name;
You get the answer like this.
Orcl.usa.com
Now, go to Listener.ora file and change global_name to the new name (orcl.usa.com)
restart the listener.
WE WILL SEE ABOUT THE CHANGES OF TNSNAMES.ORA LITTLE LATER.
Now, go to second server(server Y) and perform the same operation as defined above. i.e. Specify the db_name, db_domain in init.ora file, execute "alter database.." command for setting global_name and edit listener.ora file for new global name.
Once you do all these you need to create service on server 1 to connect to server 2 and on server2 to connect to server1.
Go to server X.
Open tnsnames.ora file and create an entry like this.
P =
(DESCRIPTION =
(ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(Host = IP address of B)(Port= 1521)))
(CONNECT_DATA = (SID = P))
Here, P is global name of P ( at both the places).
Now, go to server Y.
Open tnsnames.ora file and create an entry like this.
Q =
(DESCRIPTION =
(ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(Host = IP address of A)(Port= 1521)))
(CONNECT_DATA = (SID = Q))
Here, Q is global name of Q ( at both the places).
you are all set now.
Create database link between 2 servers now.
Say these are all your settings..
Server X is having database A with global_name orcl.usa.com and server Y is having database B with global_name orcl2.us.com
Now go to server X and create db link to server Y
Create public database link orcl2.us.com using 'orcl2.us.com'
(Note. don't miss to create a service 'orcl2.us.com' in server X's tnsnames.ora file)
And go to server Y and create db link there.
Create public database link orcl.usa.com using 'orcl.usa.com'
(Note. don't miss to create a service 'orcl.usa.com' in server Y's tnsnames.ora file)
hope this helps,
If this doesn't work, feel free to contact me.

<BLOCKQUOTE><font size="1" face="Verdana, Arial, Helvetica">quote:</font><HR>Originally posted by cindy spearman ([email protected]):
Before creating the link, I went into my init.ora file and made sure the GLOBAL_NAMES entry was false.
I then created a database link using the following:
create public database link cindy_link
connect to system identified by syspswd
using 'PRECISEI';
My link was created, but when I attempt to use it, I get the error:
ORA-02085:database link CINDY_LINK.WORLD connects to PRECISEI.WORLD
Here is the entry from my tnsnames.ora file:
PRECISEI =
(DESCRIPTION =
(ADDRESS_LINK =
(ADDRESS =(PROTOCOL = TCP)(HOST = taurus)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = precisei.world)
Here is the entry from my listener.ora file:
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = precisei.world)
(ORACLE_HOME = E:|oracle\ora81)
(SID_NAME = precisei)
(I must admit to not having a full understanding of SID_NAME vs SERVICE_NAME.) I looked in dba_db_links, and my db_link is named CINDY_LINK.WORLD instead of CINDY_LINK.
Do I have a problem in one of my files?
I would really appreciate any help.
Thanks.<HR></BLOCKQUOTE>
