View 1 Replies View RelatedConnecting Oracle to SQL Server via database link.
I am trying to connect from Oracle 10G to a SQL Server database. I have looked at the manual and i will admit that i am finding the documentation quite difficult to follow. There seems to be several options to use but none of the documentation describe how each option works.
As an example, i have been given the following information on the database i need to connect to (i.e. the SQL Server database)
- Username
- Password
- Database Name [lets assume the database name is data_extract]
To connect the above i made the following changes
$ORACLE_HOME/hs/admin/inithsodbc.ora
---------------------------------------
HS_FDS_CONNECT_INFO = data_extract
HS_FDS_TRACE_LEVEL = 0
$ORACLE_HOME/network/admin/tnsnames.ora
---------------------------------------
sqlserver.db =
(DESCRIPTION =
[code]....
Note: In listener.ora, i only added the last SID_DESC entry. I then went on and created the database link as shown below
create database link sqlservdb using 'sqlserver.db';
When i try to access a table i get the following error
sqlplus> select * from TESTTABLE@sqlservdb;
select * from TESTTABLE@sqlservdb
*
ERROR at line 1:
ORA-28545: error diagnosed by Net8 when connecting to an agent
Unable to retrieve text of NETWORK/NCR message 65535
ORA-02063: preceding 2 lines from ORASQLSERVER
A couple of things i am not sure of:
- Where do i specify the username and password to access the sql server from the oracle db to the sql server db
- Having read around on the internet, i can see some people refering to a DSN datasource. I am told that the information that i have is all i need. Is this correct or do i need something else?
- The sid i specified in inithsodbc.ora and tnsnames.ora is actually the sql server database. Is this correct?
i would like to import a table from another database by using database link.
impdp muba/muba tables=FUNCTION_NO directory=testdump NETWORK_LINK=DBLINK1
i created the public database link as system user
it gave error like

I am having database A and database B and I am inserting into database b by selecting some records from database a using db link.Is there any way to find whether database link is being used?

Is this possible to run a direct impdp with database link for transport tablespace instead of first creating export dump and then using impdp.
I tried the below command and it shows up error.I have gone through the entire Oracle docs but could not find the exact command with network link for transport tablespace.
$impdp system/passwd DIRECTORY=data_pump_dir transport_tablespaces=TBS1,TBS2,TBS3 LOGFILE=tbs.log network_link=dblink
UDI-00015: invalid context or job state for parameter, 'transport_tablespaces'
I tried to find how to import whole schema over db link , can below command use for whole schema import
CREATE DATABASE LINK EXP_SAT CONNECT TO SYS IDENTIFIED BY SYS USING 'PRTRD01'
IMPDP SYS/SYS@PRTRD01 directory =EXP_SCHEMA NETWORK_LINK = EXP_SAT remap_schema = STG_CUPID_RP2:STG_CUPID_RP2;

on my Windows 7 machine with Oracle Client 12.0.1.0 installed I'm trying to create a database link to a database server, that runs under Oracle Standard Edition1 11.2.0.2. When i login to sqlplus on the client with "sqlplus /nolog" and type the command : SQL> create database link SID connect to user identified by passwd using 'tnsnames.ora connection'; I'm getting an SP2-0640: not logged in.
Ok, thats clear, because i use sqlplus with /nolog option. But on client side normally I have no database, where I can login. So I think, there will be no user, or? The database to which I want to connect is set in tnsnames.ora. Generally: Is it possible to use the Oracle Client to create a database link?
I'm trying to connect Oracle 11g database from Oracle 9i database, by creating dblink on Oracle 9i database. But my session got hang while i perform this. Here i'm giving the steps i followed on my both the database. Here Oracle 9i database is my source db and Oracle 11g is my target db.

I have been trying to link/connect Oracle XE 10g to Sql Server 2008 Express using Oracle heterogeneous services without any luck. I have MS ODBC drivers loaded on my PC which I know work as I can create and test the connectivity of a DSN which is successful, however when I try to link Oracle to that ODBC driver I get the following error message.
TNS-12545: Connect failed because target host or object does not exist.
Here is listener.ora file.
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =

Here is how the tnsnames entry is defined.
SqlServer =

(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = MYPC-LT)(PORT = 1521))
)
(CONNECT_DATA =

)
Here is a copy of the initSqlServer.ora file.
# This is a sample agent init file that contains the HS parameters that are
# needed for an ODBC Agent.

# HS init parameters

Just to be clear the ODBC DSN is named "SqlServer". I followed through all of the steps outlined in the following URL.

There seems to be a disconnect between the ODBC driver and SQL*Net. Possibly due to Oracle HS?

View 1 Replies View RelatedWe got a big problem that we have a db link to connect to sql server(big 5).
In original setting, there is no Chinese characters in the data. We simply grab the data from sql server and do not have any issue. But now we have data with Big5. When we import the data into our Oracle DB, which uses UTF8, all the text becomes "?
Changing character set in DB is not possible. We need to convert the text into unicode format, or allow oracle/sql server to convert it automatically.
My user would like to have a way to attach files to database records. For simplicity, we'll say that each employee in the database could have 0-many file attachments associated with them. I know how to make this part work using Oracle Forms.
So that's the easy part for me. The tough part is that they want to be able to run an Oracle Report on our application server (displays as a PDF, also downloadable as a PDF) and have links on this report to the attachments that they uploaded using the forms process above.
For the idea of storing the files on a folder somewhere, I simply created a text object on the report that had it's hyperlink property pointing to the file location. Done.. opens fine.
However, I want to be able to have the option of storing these files in the database instead, just in case we can't go with the shared folder idea. I'm not sure how to make this work. I can store a blob in the database.. but how do I link to that blob on the report for them to be able to download it? Is this even possible?
how to create a download link on the Oracle Report that let's them download a file out of the database.
Is it possible to use Database authentication in APEX through database link, and how?Also is it posible to read roles from users through database link?

I am newbie to oracle database.
I am using oracle 9i version and in EMCA satndalone application . I have created database links.
The database links have been created, and three databases are local.
When i am pressing the test button in emca . It gives notification database link not active.
What should i do?
A procedure in a package uses a database link. The database link is defined without a username and a password. The user that uses the database link is supposed to be present in the opposite database as wel.
When the procedure is started in SQL*Plus or TOAD it runs perfect. But the procedure has to run in a scheduled job. And that doesn't work. The procedure fails because of: ORA-01017 invalid username/password. The user that is used to run the scheduled job is the right one.

I have a staging which connects to RAC clusters via dblink..I have a scenario to collect the hostname,systimestamp whenever i do a query from this rac clusters
So in general below would be cool
select UTL_INADDR.GET_HOST_NAME,sysdate,x,y,z from gv$symmetric would work perfect
But on dblink..
select UTL_INADDR.GET_HOST_NAME,sysdate,x,y,z from gv$symmetric@dblink.is returning local timestamp and hostname which is not intended
So i even tried subquery..
select (select host_name,systimestamp from v$instance),t UTL_INADDR.GET_HOST_NAME,sysdate,x,y,z from gv$symmetric@dblink
this would work in certain case ...But it certain cases it would throw an error saying mutiple rows from asubquery .All ineed is to get hostname,systimestamp append to all sql i fetch from any this rac clusters through this dblinks.
