Heterogeneous Connectivity :: Connecting MS SQL Server From Oracle Using DBLink?
Nov 12, 2013
Oracle 11g on linuxdestination : ms sql server 2005 i need to create the db link from oracle to ms sql server to view the tables , is it posibble without configuring the gateways( as looks like it is licenced product)
i have created the DB LINK from Oralce 11gR2 to MS Sql Server 2005,able to access the view of Sql Server from Oralce,but the Columns which have Datatype nvarchar(max) in Sql Server am not able to access through DB Link.
I am working on oracle and pl/sql since some time. so just a novice. I don't know much about sql server or transact sql, etc..I have a requirement to create an interface between Oracle and sql server.
we have a database on oracle and another on sql server. my requirement is to create an interface between oracle and sql server and see how can I update one (or more) tables (I am guessing using pl/sql) on sql server.
we have microsoft sql server, oracle gateway server (11G) and database server (10.2.0.5) we already make the full setup, and it's working.
we create materialized view into oracle server to read a data from sql server, but the refresh of MV take long time so we are planing to create the materialized view into oracle gateway server.
create MV into oracle gateway server?i mean i don't want to download oracle database instance for only one MV.
I have installed unixodbc 2.3.1, postgres odbc driver (psqlodbc-07.03) and dg4odbc 11.2..On querying : select sysdate from dual@dblink_postgresql, the following error occurs:
ORA-28500: connection from ORACLE to a non-Oracle system returned this message: [unixODBC][Driver Manager]Can't open lib '/oracle/psqlodbc/lib/libpsqlodbc.a' : file not found {01000} ORA-02063: preceding 2 lines from DBLINK_POSTGRES
Similar error appears in the trace file as well.
[unixODBC][Driver Manager]Can't open lib '/oracle/psqlodbc/lib/libpsqlodbc.a' $ isql -v postgresql postgres postgres@2012 [01000][unixODBC][Driver Manager]Can't open lib '/oracle/psqlodbc/lib/libpsqlodbc.a' : file not found [ISQL]ERROR: Could not SQLConnect
However the file is present in the location and has no permission related problems.
$ pwd /oracle/psqlodbc/lib $ ls -lrt total 2952 -rwxr-xr-x 1 oracle oinstall 663 Mar 25 15:28 psqlodbc.la -rw-r--r-- 1 oracle oinstall 731419 Mar 25 15:28 libpsqlodbc.a -rw-r--r-- 1 oracle oinstall 12215 Mar 25 22:11 win_md5.o -rw-r--r-- 1 oracle oinstall 18100 Mar 25 22:11 options.o [code]....
select from the postgre databse works just fine (however when i select data column alone it returns as date, if i select it together with som condition in where clause it returns varchar).
-- this runs ok select t."idbill", t."idpoint" from "crm"."bills2points"@dl_carecloud t ,"crm"."bills"@dl_carecloud brg where 1=1 and t."idbill" = brg."idbill" and t."idbill" = 9685; [code]....

Oracle 11gR2 Linux 6.x Sybase 12 (on Windows) unixODBC 3.2.x Sybase Client 12 ------------------------
Given the following files or structures that are important to the proper operation of the ODBC Gateway connecting to a remote Sybase database:
listener.ora tnsnames.ora initmydblink.ora ( my version of the initdg4odbc.ini ) dblink (not a file but the dblink in the Oracle database) odbc.ini odbcinst.ini
What files (and what properties within those files) may/must be changed if the remote Sybase db and system is different (i.e. the Sybase database source has been changed to something 'new')? For example, I can that the odbc.ini file is going to have to be alterer to point to the new database server IP address, database port, database name?
I am using oracle 11g express edition and MY Sql database How to establish database link between them using ODBC gateway. I am using ODBC gateway Mysqlodbc connector.
Is there any way to control the timeout before connecting via dblink. the idea is to test the dblink before calling functions over it, the problem it when i try 'select 1 from dual@dblink' in case if the remote server is down it takes too long time 5-7 min. which causing hang up the session,
So is there any parameter to reduce the waiting time say after 3 sec stop and return the timeout exception.I try the SQLNET.INBOUND_CONNECT_TIMEOUT parameter but not working, also try the tnsping but it alse take long time when the server down.
I was trying to connect to SQL server from Oracle using Oracle heterogeneous services (HS).But I found that I do not have HS installed on my system. It was mentioned in Oracle website that we need to run 'caths.sql' script under the path $ORACLE_HOME/rdbms/admin.
But I do not have any such folder(rdbms) in my $ORACLE_HOME.What does it mean? And how can I install HS alone on my system(Since I already have oracle)
I have installed Oracle server and SQL Server on separate machines which cause me a time delay of 21 seconds for each execution. Why executions delay? I have set RPC out (true).
Note: My main concern is either if the query is correct/incorrect it executes for 21 seconds._
Another case when I have both servers on the same machine it executes in milliseconds. I have tried Following methods in SQL SERVER.
*1, Using OPENQUERY:* SELECT * From OPENQUERY(Linked Server Name,’Select * from OracleTableName ‘)
*2, Using Exec:* DECLARE @sql NVARCHAR(MAX); SET @sql =(’Select * from OracleTableName ‘); EXEC (@sql) AT Linked Server Name ;
How to reduce the time delay caused for the execution?
I'm trying to make a connection to sql server from an ORACLE 8.0.4 (I know, it's ancient) but can't seem to get it to work. I've read a lot of articles on the internet regarding the Heterogeneous Services but just can't get it to work on my system. Therefor I tried an example on connecting to an Excel workbook I found on another forum [URL] but that gives me the same problem as with connecting to sql server.
Here is what I've got: initFRUIT.ora CODEHS_FDS_CONNECT_INFO = SPONGE HS_FDS_TRACE_LEVEL = OFF LISTENER.ORA CODESTARTUP_WAIT_TIME_LISTENER = 0
[code]....
One thing I noticed is that I do not have an hsodbc.exe file in my \bin, should it be there? (I also tried Tgmsql80 in stead of hsodbc as program in Listener, resulting in an extended time of testing the connectivity but with the same result)
Is there any way I can test parts of the connection to limit the location of the problem? (e.g. does the listener get to the TNS)
connecting two oracle database in two different server.I installed Oracle 10g XE in both system.Both system act as Server.I need to connect both server using database link concept.
how to use the tnsnames,ora and listener.ora file for connecting both system.
Connecting 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]
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?
We have a 2 node RAC installation on IBM AIX 5.3 with Oracle Standard Edition. We need to create a manual standby database (becoz Standard Edition does not allow Dataguard confign). Can we do this on a different platform (eg: Linux/Windows). This is to make use of existing servers for the standby environment.
I Have installed the oracle database 11g, the oracle database mobile server and i use Glassfish as the application server. Everything is fine i have tested the mobile server configuration using Oracle mobile server workbench the mobile server runs but when i want to connect to the mobile manager workspace via the browser using
[URL].......
I have a server error HTTP 404- The requested resource () is not available .
I would like to develop a system with Oracle 9i as the database and PHP 4/5 as the front end. I am not able to establish the connectivity to the database. What should I do now ?
I have a requirement wherein I need to access the MS ACCESS database table from Oracle Client.I have created ODBC data source and have configured tnsnames.ora and listener.ora for the same. As a next step I am trying to configure HS init file for hsodbc connection but couldn't find the directory hs in $ORACLE_HOME (<ORACLE_HOME>hsadmininit******.ora). Any patch that needs to be applied for hsodbc connection in the server.
I am currently using Oracle 10.2.0.1 version, in a single PC (test server) and MS-Access (2003) in it.
I was trying to use the logic of HS ODBC connectivity, but when i try to select the table from the MS-Access i am getting the following error.
"ORA-12154: TNS:could not resolve the connect identifier specified".
to create the successful connection between the MS-ACCESS and ORACLE. I just need to read some data from MS-ACCESS on a monthly base from a particular table.
I just created a dblink from our Oracle 9i database to a SQL Server 2008 R2 Server using oracle heterogeneous services. The dblink seems to be OK and I can query the remote SQL Server database but I only get results for numeric columns.
Say the remote SQL Server table was created like:
CREATE TABLE [MITLOC] ( [MLCONO] [numeric](3, 0) NOT NULL, [MLWHLO] [nchar](3) NOT NULL, [MLITNO] [nchar](15) NOT NULL, [MLWHSL] [nchar](10) NOT NULL, [MLBANO] [nvarchar](20) NOT NULL, [MLCAMU] [nvarchar](20) NOT NULL, [MLFACI] [nchar](3) NOT NULL, [MLWHLT] [nchar](2) NOT NULL, [MLSTQT] [numeric](15, 6) NOT NULL)
The remote dblink is named after M3PREP.
Then if I run:
CODEselect MLCONO, MLSTQT from MITLOC@M3PREP => this works OK and I get the two columns.
If I run:
CODEselect * from MITLOC@M3PREP => I get the same results as in the previous query and all nchar, nvarchar type columns are missing, I only get the same two columns.
If I run:
CODEselect MLCONO, MLWHLO from MITLOC@M3PREP=> I get ORA-00904 - the column name entered is either missing or invalid.
I set up my .ora init file like this, I suspect there is something missing here, is it related to the NLS_LANG or so?
We are accessing data from the server ADM.WORLD by using DBLINK.We got the following error.
PL/SQL: ORA-04052: error occurred when looking up remote object sysadm.PS_HP_INC_ELIG_VW@ADM.WORLD ORA-00604: error occurred at recursive SQL level 1 ORA-28000: the account is locked ORA-02063: preceding line from ADM
For that we checked in the server ADM.WORLD for the account the account is showing locked .After that we successfully accessed the object sysadm.PS_HP_INC_ELIG_VW@ADM.WORLD.
For next day also the account is locked.Why the account is frequently locking.
