Owb and database link creation

hi everybody....
I installed oracle 10g and owb on the samo machine (windows xp). When trying to create oracle module in owb it is required to create database link (is there any workaround?). But how can I create database link to local database when connected to local database???? Can anybody help me???
thanks in advance

thanx for your reply... I alredy tried everything.. but I always get this error:
Testing...
Failed.
SQL Exception
Repository Error:SQL Exception..
Class Name: CacheMediator.
Method Name: getDDEntryFromDB.
Repository Error Message: ORA-28546: connection initialization failed, probable Net8 admin error
Oracle instance works properly.. but I can not create Oracle module from OWB. Here is my tnsnames.ora file:
ORCLANTI.LOCAL.HOST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = antix.login.net)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orclanti)
EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
(CONNECT_DATA =
(SID = PLSExtProc)
(PRESENTATION = RO)
here is my sqlnet.ora file
SQLNET.AUTHENTICATION_SERVICES= (NTS)
NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)
NAMES.DEFAULT_DOMAIN= local.host
and here is my listener.ora file
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = E:\ora10g)
(PROGRAM = extproc)
(SID_DESC =
(GLOBAL_DBNAME = orclanti.local.host)
(ORACLE_HOME = E:\ora10g)
(SID_NAME = orclanti)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = antix.login.net)(PORT = 1521))
username and password are correct and db link name is ok!
Now, do I have to enter SQL*Net connect string or hostname and oracle service name???
I repeat... I already tried almost every combination!
Thanks again
maybe this is an Oracle configuration error because I am pretty new to this RDBMS :)
another question:
1. is ti possible to create a database link to local database (for example if I am connected to local database on my machine can I create database link from that database to same database but for another schema)???

Database Link Creation and Acessing

i want to talk between two oracle server. i decided to go for snapshot creation with periodical refresh. For which i am having two oracle server's with different ip address located inside our office setup.
I have created a database link between two servers.
first server name global
userid scott
password tiger
second server name asil
userid scott
password tiger
both the user have been given dba rights.
in both the server the services and listners are all started. i gave the following command to create database link.
from asil server
create public database link global connect by scott identified by tiger using 'global'
the command was successful and the link was created. Now i tried to access a table of the scott user of the global server.
select * from emp@global;
now it is giving error. I want to know how the link can be created and how it can be accessed. i refered the 8i online documentation and done the things based on that. i expect valuble solution from all possible persons

help me to create the database link in between these two databases..........

Hi, I have read carefully your letter.
Firt of all, when you use 'current_user' statement you must guarantee that such users have in both databases.If users exist in both databases and the error will appear again than try create database link with the option 'PUBLIC' as follow:
CREATE PUBLIC DATABASE LINK REMOTE_CONNECT connect to scott identified by tiger using 'ORAC';
and check the creation:
SQL> COL OWNER FORMAT a10
SQL> COL USERNAME FORMAT A8 HEADING "USER"
SQL> COL DB_LINK FORMAT A30
SQL> COL HOST FORMAT A7 HEADING "SERVICE"
SQL> SELECT * FROM DBA_DB_LINKS;
OWNER DB_LINK USER SERVICE CREATED
PUBLIC REMOTE_CONNECT.US.ORACLE.COM SCOTT ORAC 17.04.06
if the error appear again than checks parameter 'open_links' for your database instance. Default is 4. Increase that number. Good luck.Let me know if something go wrong.

Database link creation

Hi i want to access the data from production to test
let the production named as naren and other one as naren1
this link has been created in naren
create database link test
connect to naren
identified by naren
using 'test'
conn naren1/naren1;
i want to access one of the table from naren
select * from emp@test
ora-02019 connection description not found
is it the problem of priviliges or tnsnames

First make sure you have tns name entry for prod in tnsnames.ora
When you create the database link like below,
CREATE DATABASE LINK dblink_name CONNECT TO remote_username IDENTIFIED BY remote_password
USING 'tns_service_name';The tns_service name is the tnsname for PROD not TEST.
Say if your tnsnames.ora file look like this for your PROD connection, You need to use the service_name value for the 'tns_service_name' above. In the below case it is 'ganesh'
GANESH=
(DESCRIPTION=
    (ADDRESS=
      (PROTOCOL=TCP)
      (HOST=GANESH)
      (PORT=1521)
    (CONNECT_DATA=
      (SERVER=dedicated)
      (SERVICE_NAME=ganesh)

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.

Global_name and database link

I have Windows XP with 10.2.0.1.0
I have made my database global_name to be junk.points.com.
And, I create a database link as:
create database link preview using 'xxxxx';
the db_link is preview.point.com.
However, if I use the following command:
create database link preview.system using 'xxxxx';
the db_link is preview.system instead of preview.system.points.com.
I expect the db_link should be preview.system.points.com. Please help.
Thanks

Hi,
Specify the complete or partial name of the database link. If you specify only the database name, then Oracle Database implicitly appends the database domain of the local database.
If the value of the GLOBAL_NAMES initialization parameter is TRUE, then the database link must have the same name as the database to which it connects. If the value of GLOBAL_NAMES is FALSE, and if you have changed the global name of the database, then you can specify the global name.
Defining a CURRENT_USER Database Link: Example
The following statement defines a current-user database link to the remote database, using the entire service name as the link name:
CREATE DATABASE LINK remote.us.oracle.com
CONNECT TO CURRENT_USER
USING 'remote';
The user who issues this statement must be a global user registered with the LDAP directory service.
Please view the below document.
http://www.stanford.edu/dept/itss/docs/oracle/10g/server.101/b10759/statements_5005.htm
http://download.oracle.com/docs/cd/B28359_01/server.111/b28310/ds_admin002.htm
And please check the db links you posted one is having __.point.com
and the other one is having ___.points.com
Please make sure you are using the GLOBAL_NAMES set true and displaying correct dblink .
Hope this will be helpful :)
Thanks,

ODP AND DATABASE LINKS ???

Hi, some very weird stuff going on here:
When I bind data to my datagrid, if it comes through a database link in any way (either I code to access via a database link or I create a view with the link in it) I get only the first two chars of every field. Really weird, any ideas:
You can see four sql lines below- The only one that works is one that is a view on the local database(not the data i need), all the others only return first two chars of every item via the db link. In case two I created the view with the link in it.
Code in my DAL:
Public Function returnTissues(ByVal inFrom As String, ByVal inTo As String) As DataTable
Dim tissues As New DataTable
Dim command As New OracleCommand
Dim adapter As New OracleDataAdapter
Try
Dim sql As String = "select specimenid, status, sampletype, form, species from [email protected] where specimenid between '" & inFrom & "' and '" & inTo & "'"
'FAIL-Dim sql As String = "select specimenid, status, sampletype, form, species from specimen_view_sbat where specimenid = 'ONC000100'"
'PASS-Dim sql As String = "select * from request_view"
'FAIL-Dim sql As String = "select s_sampleid from [email protected] where s_sampleid = 'MGH000167'"
command.CommandText = sql
command.Connection = Me.globaldal.msdb
adapter.SelectCommand = command
adapter.Fill(tissues)
Return tissues
Catch ex As OracleException
Throw ex
Finally
End Try
End Function
Here is the page code:
Private Sub ButtonSearchByRange_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ButtonSearchByRange.Click
Dim fromvalue As String
Dim tovalue As String
fromvalue = TextboxFrom.Text
tovalue = TextBoxTo.Text
DataGridTissues.DataSource = tissuedal.returnTissues(fromvalue, tovalue)
DataGridTissues.DataBind()
End Sub
Also, I will materialize the view and try it, but it has got to be the ODP, the sql executes fine via slqplus, toad, etc, and It's not the grid, I bound the first column to a dropdown and got the same result.
My ENV:
Local DB 8.1.7.3 - I think
Remote DB 9 release 2
OPD: 9.2.0.4.01

Further testing has revealed:
The database link works fine when connected to another 8.1.7.4 instance as opposed to the 9.2.0.3.0 instance.
It makes no difference if the link is public or private.
Creating a materialized view with the database link in it to the 9.2.0.3.0 instance also works fine.
However none of the above is a solution.

Portal and Database Links

We are running Portal 3.0.9.8.0. I am wondering if anyone has come across away to disable the ability of users to create database links.

Hi,
You can do it only by revoking the "create database link" or "create public database link" privilege from the database schema
to which the portal user is connected.
For example say there is a user "erin" mapped to the database schema portal30, then you should go to the
"Administer Database" tab and edit the schema using the "Schemas" portlet. In the roles tab remove "create pubic database link"
or "create database link" privilege.
This might help. But be careful not to remove the privilege from the portal schema, unless you do not want to create any
database links as the portal schema.
Thanks,
Sharmila

BLOBs and Database Links

Do Blobs work through Database Links? I have images in one database that I would like to render in a portal attached to another.

Hi I tried the following in sqlplus:
1)create a table(ATAB_CLOB) in a remote database(DB2) with a clob column
2)connect to the database(DB1) and create a database link (ADBLINK1) for the
remote database(DB2) .
3) create a synonym (ASYN_TAB) based on the remote table (ATAB_CLOB) using the
database link ADBLINK.
4) Now try to create a view based on this synonym,I see the same error:
SQL> create or replace view aview2 as select * from asyn_Tab;
create or replace view aview2 as select * from asyn_Tab
ERROR at line 1:
ORA-22992: cannot use LOB locators selected from remote tables
The message says it all.
This is a database limitation.
Hope this helps.

Clones and database links

Hi,
I have generally found that after an instance (E-Business Suite) is cloned, the database links do not work in the cloned instance, and have to be recreated.
Is there a reason why the database links do not work, as the target instance (in the db link) and its credentials remain the same?
Thanks
Jai

Hi Carlo,
I am not the DBA, so will not be able to answer any of your questions.
I am in the Development team and just found it odd that a DB link needs to be re-created after a clone, even though all the information remains the same. The DBA team was not able answer my question - they just said that it is a step that needs to be done. I do not know how the tnsnames entries look, but I assume that is somehow having an impact as mentioned in the prior posts.
Thanks

Problems with domain name in global_name and database links

I have to create a database link on Oracle 9i **without** a domain. Somehow whenever I create a database link, a domain is added. This domain seems to be the domain that is also added to the database global name (and is the same as my TCP/IP domain on my windows machine).
I tried to create the db link:
create database link "TEST"
connect to remotedb
identified by mypassword
using 'myservicename';
and get:
TEST.DOMAIN.COM instead of TEST.
I also tried to change my database global name:
alter database rename global_name to NEWNAME
and still the database name is NEWNAME.DOMAIN.COM
So there does not seem to be any way to remove the domain.
Note that:
- db_domain is not set in init.ora
- names.default_domain is not set in sqlnet.ora
- global_names = false
So... how to get rid of the domain part?

Hi,
this is not what you want to hear, but once a global_name has a domain associated with it you can't get rid of it, you can change it to a different domain with the alter database command but not to null and it is this domain that will always get appended as default to your db link name so your stuck with it

Oracle Application server connection pool and database links

I am using Oracle application server 10g with connection pools, the db used by the application connects to another oracle db using a database link. My question is when the application starts it creates 10 connections, does it also create x amount of database links as well?

Hi,
Is there any way to use the connection pool or Datasource while connecting to database?If I am using a stateless sesssion bean and using a Data Access layer which just creates a database session to write the persistence toplink objects how I can make use of application server connection pool?Hi Vinod,
Yes, TopLink allows you to use the app server's connection pooling and transaction services. Chapter 2 of the Oracle9iAS TopLink Foundation Library Guide provides details as do the TopLink examples. The easiest way to set this up is by using the sessions.xml file. The sample XML below is from the file <toplink903>\examples\ias\examples\ejb\sessionbean\sessions.xml. Here we are adding the datasource defined in OC4J and specifying that we are using the OC4J transaction controller also.
<login>
<user-name>sa</user-name>
<password></password>
<datasource>java:comp/env/jdbc/ejbJTSDataSource</datasource>
<uses-external-transaction-controller>true</uses-external-transaction-controller>
<uses-external-connection-pool>true</uses-external-connection-pool>
</login>
<external-transaction-controller-class>oracle.toplink.jts.oracle9i.Oracle9iJTSExternalTransactionController</external-transaction-controller-class>
When using this approach you need to change your TopLink code slightly in the EJB methods:
a. Acquire the ACTIVE unit of work from the server
session (again, see the EmployeeSessionEJB code
example) with something like:
UnitOfWork uow = clientSession.getActiveUnitOfWork();
b. Calls to uow.commit() can be ommitted or commented out
because the EJB will handle this. Note that of course
the methods you create in the EJB that are using this
approach must have TX Required (default).
Hope this helps.

Jdbc (oci8) and database link ?

hello,
i try to select * from dual@DBNAME within a jdbc connection.
1. we are connected with oci8 on a 9.2.0 database
DriverManager.registerDriver(new oracle.jdbc.OracleDriver());
String urlDefault = "jdbc:oracle:oci8:@DBM1.uvwendy";
String url = null;
2. then we prepare a statement
rset=dblink_stmt.executeQuery ("select name from v$database@"+Database_Server+"_"+Database_SID+".UVDBM");
while (rset.next ())
System.out.println (rset.getString (1));
} catch (SQLException e) {
System.out.println ("Error REMOTE SELECT ..." + e);
3. the error looks like this
select name from v$database@UVGENEVA_GENEVADB.UVDBM
Error REMOTE SELECT ...java.sql.SQLException: ORA-12154: TNS:could not resolve service name
but when we execute the same statement in the database self then it works fine.
the database link works fine.
has anybody an idea for this behaviour?
thank you very much,

OWB 10g -- Can't Create Database Links for Data Source and Target

We installed OWB 10g server components on a Unix box running Oracle 10g (R2) database. The Designer Repository is in one instance. The Runtime Repository and the Target are in another instance. The OWB client component was installed on Windows XP. We create a data source module and a target module in OWB. The data source is on another Unix box running Oracle 9i (R2) database. We try to create database links for data source module and target module, respective. But when we created and tested the DB links, the DB links were failed.
For the database link of data source, we got the following error message:
Testing...
Failed.
SQL Exception
Repository Error:SQL Exception..
Class Name: CacheMediator.
Method Name: getDDEntryFromDB.
Repository Error Message: ORA-12170: TNS:Connect timeout occurred
For the database link of target , we got the following error message:
Testing...
Failed.
API2215: Cannot create database link. Please contact Oracle Support with the stack trace and the details on how to reproduce it.
Repository Error:SQL Exception..
Class Name: oracle.wh.ui.integrator.common.RepositoryUtils.
Method Name: createDBLink(String, String, String, String).
Method Name: -1.
Repository Error Message: java.sql.SQLException: ORA-00933: SQL command not properly ended.
However, we could connect to the two databases (data source and target) using the OWBs utility SQL Plus.
Please help us to solve this problem. Thank you.

As I said prior the database link creation should work from within the OWB client (also in 10).
Regarding your issue when deploying, have you registered your target locations in the deployment manager and did you first deployed your target location's connector which points out to your source?
I myself had some problems with database link creations in the past and I can't remember exactly what they were but it had something to do with
- the use of abnormal characters in the database link name
- long domain name used in as names.default_domain in my sqlnet.ora file
What you can do is check the actual script created when deploying the database link so see if there's something strange and check if executing the created script manually works or not.

A question about CREATE PUBLIC DATABASE LINK and ORA-12154 error

Dear all,
I have a problem about public database link creation and I would appreciate if you could kindly give me a hand. I have the following connection parameters in my
tnsnames.ora file:
DGPAPROD.WORLD =
     (DESCRIPTION =
       (ADDRESS_LIST =
        (ADDRESS = (COMMUNITY=tcp.world)
          (PROTOCOL=TCP)(HOST=ORASR001)(PORT=1521)
       (CONNECT_DATA = (SID = DGPAPROD))
...Having the above mentioned parameters I can connect to this remote database directly in a SQL*Plus shell:
$ sqlplus username/[email protected] works pretty well and the connection is established without any problem.
Now, what I would like to do is to create a public database link to this remote database in order to avoid the user/connection switching for viewing the
content of this database. I proceeded according to the syntax indicated in the Oracle online documentation:
http://download.oracle.com/docs/cd/B28359_01/server.111/b28286/statements_5005.htm#SQLRF01205
Therefore I run the following in order to create a public database link
CREATE PUBLIC DATABASE LINK SR001_dblink CONNECT TO user IDENTIFIED BY password USING 'DGPAPROD.WORLD';Apparently there is no error and the link is created successfully. However it cannot resolve the remote host and whenever I run the following query
(myenterprise is the name of a table in that remote database)
SELECT *
FROM myenterprise@SR001_dblink
ERROR at line 1:
ORA-12154: TNS:could not resolve the connect identifier specifiedWhat causes this problem?
Thanks in advance,
Kind Regards,
Dariyoosh

You must have defined DGPAPROD.WORLD in tnsnames.oar on server where you DB is runnig.Hello there,
Thanks a lot for this nice solution. In fact I had to add the connection parameters into the tnsnames.ora file of the server on which the link was created (not the tnsnames.ora of my oracle client stored on the localhost)
After a bit googling I found another solution that allows to create the database link:
CREATE PUBLIC DATABASE LINK SR001_dblink CONNECT TO user IDENTIFIED BY password USING '(DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (COMMUNITY=tcp.world)
(PROTOCOL=TCP)(HOST=ip_adresse)(PORT=1521)))(CONNECT_DATA = (SID = GPAPROD)))';Thanks a lot for your help!
