How to resolve database link issue???
Hello all,
actuall i want to access a remote database server which is basically an Oracle8 server and i want to access that server while sitting in Oracle8i server....
I have tried create database link but it's not functioning properly ..........
it's giving an error some think like "Can not resole TSN Service name....."
Now plz help me to resolve that issue and kindly tell me all the pre-requsits and plz send me a piece of code as well..................
Thanks In Advance,
Omer Saeed Khan.
it's giving an error some think like "Can not resole TSN Service name....." Honestly. Give us a proper error message with a number. "something like" is not good enough.
Have you read the documentation?
http://download-west.oracle.com/docs/cd/A87860_01/doc/server.817/a76960/toc.htm
If I have to guess I'd guess that you haven't included the remote database in the server-side TNSNAMES.ORA file.

How to improve database link performance?
Hello all,
We use db links to do DML operations on remote databases. For OLTP applications we are facing performance problems for transactions dependent on data on remote database.
For legal and business reasons we cannot state all the data locally.
Could anybody suggest how to improve database links performance or suggest methods/procedures/techniques to enhance speed of OLTP applications going against remote databases ?
Thanks
SkyAQ is as reliable as Oracle-- the guarantees about delivery of queued messages are the same as the guarantees about committed transactions (i.e. ACID). AQ is designed for asynchronous operation, though. If you are batching transactions, it sounds like you are already doing some sort of asynchronous operations-- I've generally found AQ a lot easier to administer & maintain than rolling your own batching system.
If you want to tune the Oracle side of things, you'll need to explain more about the system(s) involved here. Architecture, data flow, operations that involve the dblink, etc. If you're not comfortable posting that sort of information to a public forum, feel free to send me mail directly [email protected]
As an aside, I'm interested in how you can legally pull data from the remote system to display to your users but that you can't legally cache that data in your system via replication. Sounds like an odd constraint.

Database links issue ORA-01017 ORA-02063
Oracle 11g R1 , RHEL 5 64bit
HI all,
I am having this strange issue with my database links. They used to work in the past but now they are not. Here is what I have checked:
- All the TNSnames.ora file entries are there and are correct...I double checked with tnsping
- I changed all the passwords to be the same on all environments (DEV/QA/PROD)
- I have dropped and re-created all the database links
However, I still get the same error when I test them:
ORA-01017: invalid username/password; logon denied ORA-02063: preceding line from <database_name>
Here are the links created on DEV:
SQL> select * from dba_db_links;
OWNER DB_LINK USERNAME HOST CREATED
PUBLIC FPRCQA.FPRC.OPHTH.WISC.EDU FPRCQA 01282009
FPRCHR FPRCQA.FPRC.OPHTH.WISC.EDU FPRCHR FPRCQA 01282009
PUBLIC FPRCPROD.FPRC.OPHTH.WISC.EDU FPRCPROD 01282009
FPRCHR FPRCPROD.FPRC.OPHTH.WISC.EDU FPRCHR FPRCPROD 01282009
The above links were created using the following syntax:
SQL> conn sys as sysdba
Enter password:
Connected.
SQL> create public database link FPRCQA.FPRC.OPHTH.WISC.EDU using 'FPRCQA';
Database link created.
SQL> create public database link FPRCPROD.FPRC.OPHTH.WISC.EDU using 'FPRCPROD';
Database link created.
SQL> conn fprchr
Enter password:
Connected.
SQL> CREATE DATABASE LINK FPRCQA.FPRC.OPHTH.WISC.EDU CONNECT TO FPRCHR IDENTIFIED by <passwd> using 'FPRCQA';
Database link created.
SQL> CREATE DATABASE LINK FPRCPROD.FPRC.OPHTH.WISC.EDU CONNECT TO FPRCHR IDENTIFIED by <passwd> using 'FPRCPROD';
Database link created.
Now when I do a simple query, I get the error:
SQL> select count(*) from fprchr.department@FPRCQA;
select count(*) from fprchr.department@FPRCQA
ERROR at line 1:
ORA-01017: invalid username/password; logon denied
ORA-02063: preceding line from FPRCQA
I have read some notes on metalink, but they were talking about situations where you have a 10g database connecting to an 11g database and the whole password case-sensitivity issue, but this is not the case here as all the databases are 11g.
I would appreciate any and all help on this issue.
Thank you much.The documentation has the answer:
user IDENTIFIED BY passwordSpecify the username and password used to connect to the remote database using a fixed user database link. If you omit this clause, the database link uses the username and password of each user who is connected to the database. This is called a connected user database link.>
Since you haven't specified user/password in your public database links, then Oracle will try to create a connection on the remote db with the same user/password who is trying to use the database link. If the user doesn't exists or has a different password then you get an error (the same you mentioned in you original post)

Hi all,
While trying to create a database link i am getting the following error:
Create Database Link Failed.
ORA-01031: insufficient privileges
Could you please tell me how to create a database link.
Thanks
GrishmaHi Grishma,
Login as DBA (SYSTEM or SYS for ex.) in SQL*Plus and run this command:
SELECT *
FROM dba_sys_privs
WHERE grantee = 'USERNAME'
AND PRIVILEGE = 'CREATE DATABASE LINK'
Change the USERNAME by the USER you're trying to create the database link from. (CAPITALS!)

How to create database link between oracle and SQL Server
Hello Everyone,
Here i have Oracle Database 9i and SQL Server 2005 databases.
I have some tables in sql server db and i want to access from Oracle.
How to create a database link between these two servers
Thanks,Thanks for Everyone,
I was struggle with this almost 10 days....
I created Database link from Oracle to SQL Server
Now it is fine.........
Here i am giving my servers configuration and proceedure how i created the db link...@
Using Generic Connectivity (HSODBC) we can create db link between Oracle and SQL server.
Machine (1)
DB Version : Oracle 9.2.0.7.0
Operating System : HP-UX Itanuim 64 11.23
IP : 192.168.0.31
Host : abcdbt
Machine (2)
Version : SQL Server 2005
Operating System : Windows server 2003 x86
IP : 192.168.0.175
Host : SQLDEV1
User/PW : sa/abc@123! (Connect to database)
Database : SQLTEST (exsisting)
Table : T (“ T “ is the table existing in SQLTEST database with 10 rows)
Prerequisites in Machine (2):
a) Oracle 10g software
b) User account to access SQL Server database (sa/abc@123!)
c) Existing SQL Server Database (SQLTEST)
d) Tables (testing purpose) (T)
Steps:
1) Install Oracle 10.2.0.1 (Only SW,No need of database) *(Machine 2)*
2) Create a DSN where your windows Oracle 10g SW resides *(Machine 2)*
Control panel >> Administrative Tools >> Data Source (ODBC) >> System DSN ADD
You can follow this link also.....
http://www.databasejournal.com/features/oracle/article.php/3442661/Making-a-Connection-from-Oracle-to-SQL-Server.htm
I created DSN as
DSN name : SQLTEST
User : SA/abc@123! (Existing user account)
Host : 192.168.0.175 (machine 2)
Already I have 1 database in SQL Server with the name SQLTEST
You can create DSN with different name also (not same as db name also)
3) Create a hsodbc init file in $ORACLE_HOME\hs\admin *(Machine 2)*
Create init<DSN NAME> file
Ex: initSQLTEST
Copy inithsodbc to initSQLTEST
And edit
initSQLTEST file
HS_FDS_CONNECT_INFO = SQLTEST <DSN NAME>*
HS_FDS_TRACE_LEVEL = OFF*
save the file....@
4) Configure Listener.ora *(Machine 2)*
LISTENER_NEW =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.175)(PORT = 1525))
SID_LIST_LISTENER_NEW =
(SID_LIST =
(SID_DESC =
(SID_NAME = SQLTEST) *+< Here SQLTEST is DSN NAME >+*
(ORACLE_HOME = G:\oracle 10g\oracle\product\10.2.0\db_1)
(PROGRAM = hsodbc))
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = G:\oracle 10g\oracle\product\10.2.0\db_1)
(PROGRAM = extproc) )
:> lsnrctl start LISTENER_NEW
5) Configure tnsname.ora *(Machine 2)*
SQLTEST11 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.175)(PORT = 1525))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = SQLTEST))
(HS=OK)
:> tnsping SQLTEST11
If No errors then conti….
6) Configure a file *(Machine 1)*
Cd $TNS_ADMIN ($ORACLE_HOME/network/admin)
Create a file
$ vi TEST_abcdbt_ifile.ora
something=
(DESCRIPTION=
(ADDRESS=(PROTOCOL=tcp)(HOST =192.168.0.175) (PORT=1525))
(CONNECT_DATA=
(SID=SQLTEST))
(HS=OK)
$ tnsping something
$ sqlplus system/manager
Your connected to Oracle database *(machine 1)*
create database link xyz connect to “sa” identified by “abc@123!” using ‘SOMETHING’;
select * from t@xyz;10 rows selected.
Thanks,

Hi,
We have two databases on two differenet servers and we want both of the databases to be synched and application is running only on one server.
Is it possible through DB links if yes then how.
If any better solution than DB links is there then pl tell.850520 wrote:
I think DATA GUARD is good from recovery point of view..but i want that my application will update one database & same data will be updated on 2nd DB automatically means application need not to update second database by querying it..
Is there anything like this.And what is the second database going to be USED for? Until we know that, we can only guess at the best solution, which in any event is probably NOT database links. -

As i suggest above, please use the REMAP_SCHEMA parameter, so that you can create those objects which are getting created in the Apps Schema in the XBSI schema, I have already provided the syntax above.
ORA-31684: Object type VIEW:"XBSI"."XBSI_ORDER_LINE_INFO_V" already exists

ORA-31684: Object type VIEW:"XBSI"."XBSI_PE_FIND_RESULT" already exists
You are facing these errors as you have already done the import, and when you try to re-import it says those objects are already available. If this fresh import, Please drop the the new user you have already created in the Datawarehouse instance, and recreate the User and start a fresh import.
Hope this help!

Database Migration:Resolving DB links issue.
Hi,
We are to migrate one of our production database to a new server. The DB version is 11.2.0.3 and it is on AIX 6.1. There will be no change in version of DB or OS.
In our setup there are some number of other Oracle databases which connects to this database using DB links. We do not use DNS so, DB links are completely dependent on IP address. In this case the IP of the database server will change due to migration.
My Question, Is there any way I can determine which databases connects to this database using DB links? We need to resolve those db links post migration.
Looking for kind help. Thanks.

What I tried is to query dba_audit_trail and found a distinct list of USERHOST. These contains clients as PC/Application Servers/Other Database servers. This narrow down my search though, I can not confirm this list is 100%. DBA_AUDIT_TRAIL has a retention and there may be an application that runs twice a year.
--Gourab
Well, consider this. Your connecting clients fall into three groups:
1) End-user desktops
2) Application servers
3) other databases using db links.
Hopefully, group 2 is already well known.
Group requires a bit of research, but is actually pretty easy to collect on an ad-hoc basis.
Create two sql script files.
-- sweep_db.sql --
spool sweep_db.log
connect system/manager@db_1
@query_db_links.sql
connect system/manager@db_2
@query_db_links.sql
-- etc, etc
spool off
exit
and
-- query_db_links.sql
select * from dba_db_links.
exit
You will need to know the names and connection credentials of all possible 'client' databases in order to build 'sweep_db.sql'. And it will take a manual reading of sweep_db.log, but for a one-time effort that's not all that bad.
You may want to add some sqlplus formatting commands to sweep_db.sql
