1 How connect Oracle Database with Ms SQL Server Database By shoaib Here I have Install MS SQL Server 2005 (32- Bit) On Windows server 2003 R2 (64 Bit) So we install DG4ODBC driver (64 Bit) on Server where we install MS SQL server database. Because Windows operating system its 64 bit so

2

3 Open this gateways_odbc_64bit folder and click on open setup.exe

4

5

6 Here you only select this Oracle Database Gateway for ODBC from Components and click on Next Tab

7

8

9 During Installation this Oracle Net Configuration Assistant: window open

10

11

12 During Listener Configuration if it s give error like this so use another port number here we use 1533 port number Just click on No

13 And change port number 1533 and click on next tab

14

15

16

17

18 You can check this DG4ODBC driver successfully installed

19 After DG4ODBC driver install now configure this steps on windows where you install MS SQL SERVER 2005 Go to Start > Control Panel > Administrative Tools > Data Sources (ODBC)

20

21 This ODBC Data Sources Administrator window Open just click on this System DSN

22 From this System DSN page click on this Add tab

23 Create New Data Source page open here select SQL Server and click on Finish tab

24 Create a New Data Source to SQL Server page open Here give any name in this What name do you want to use to refer to the data source? Here we give testmssql in name tab After that in How do you want to describe the data source? give any thing Here we give in Description tab we type testmssql And in Which SQL Server do you want to connect to? tab give your host name where you install Ms Sql server 2005 here my host name its tmssql so I give tmssql in Server tab Then click on next

25

26 Here select this With SQL Server authentication using a login ID and password entered by the user And select this connect to SQL Server to obtain default setting for the additional configuration options and enter SA user and its password in password tab

27 Select this Change the default database to and here you select your ms sql server database name you want to connect here TEST1 its my ms sql server database name and click on next tab

28

29 Leave this all setting by default and click on finish

30 ODBC Microsoft SQL Server Setup page open click on this Test Data Source tab

31 Test is successfully completed and now click on Ok

32 Click on OK

33 Testmssql successfully create in system dsn tab you can find here now click on OK

34 Now you can configure this dg4odbc driver for oracle database using this steps Go to your dg4odbc home where you install Here I install on E drive go to hs folder and open this admin folder E:\product\11.2.0\tg_1\hs\admin Here create this init<sid>.ora file. You can give any name at sid. Old drive before create init file Here we create new init file. Into this initmssql.ora file look like this

35 Here at this HS_FDS_CONNECT_INFO give name as you mention in your System DSN and HS_FDS_TRACE_LEVEL also Off Same of this init.ora file its look like below # This is a sample agent init file that contains the HS parameters that are # needed for the Database Gateway for ODBC # # HS init parameters # HS_FDS_CONNECT_INFO = testmssql HS_FDS_TRACE_LEVEL = OFF # # Environment variables required for the non-oracle system # #set <envvar>=<value>

36 After creating initmssql.ora file into this admin folder its look like below Now also change into your listener file in your DG4ODBC driver home and open network and open admin folder put enter into your listener.ora file Open this E:\product\11.2.0\tg_1\NETWORK\ADMIN Here in this listener.ora file put your sid_name as you mention in this init<sid>.ora file this sid name put here at this sid_name and also put this line into this listener.ora file ENVS = "EXTPROC_DLLS=ONLY:E:\product\11.2.0\tg_1\bin\oraclsra11.dll"

37 Sample of this listener file it s below

38 # listener.ora Network Configuration File: E:\product\11.2.0\tg_1\network\admin\listener.ora # Generated by Oracle configuration tools. #LISTENER = # (DESCRIPTION_LIST = # (DESCRIPTION = # (ADDRESS = (PROTOCOL = TCP)(HOST = tmssql)(port = 1533)) # (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1533)) # ) # ) LISTENER = (DESCRIPTION_LIST = (DESCRIPTION = (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1533)) ) (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = tmssql)(port = 1533)) ) ) SID_LIST_LISTENER = (SID_LIST = (SID_DESC = (SID_NAME = mssql) (ORACLE_HOME = E:\product\11.2.0\tg_1) (PROGRAM = dg4odbc) (ENVS = "EXTPROC_DLLS=ONLY:E:\product\11.2.0\tg_1\bin\oraclsra11.dll") ) ) ADR_BASE_LISTENER = E:\product\11.2.0\tg_1

39 After that restart your listener than check your listener status it s successfully loaded

40 Now on Ms SQL Server we successfully configure this DG4ODBC driver. Now we create Service for Ms SQL server and DB Link on Oracle RAC database. Here we install Oracle 10g Rac database on another server its oracle 10g rac database ( 64 Bit ) and Operating system its Windows server 2008 Enterprise Edition Service Pack 2 (64 Bit)

41

42 Now on Oracle server edit your tnsnames.ora file You can find tnsnames.ora file at this location OracleHome/Network/admin My file here at this location C:\oracle\product\10.2.0\db_1\NETWORK\ADMIN You can write this line into your tnsname.ora file MSSQL = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = tmssql)(port = 1533)) ) (CONNECT_DATA = (SERVICE_NAME = mssql) ) (HS = OK) ) Here this description of this service MSSQL it s a service name you can write any name as you want as a service name to connect with MS Sql Server HOST = tmssql Host name of where you install Ms Sql Server. SERVICE_NAME = mssql here you mention sid name you define on Ms sql server init<sid>.ora and also in listener file at Ms Sql server sid name. HS= OK You mention this

43 After editing my tnsnames.ora file its look this below

44 After creating service on oracle RAC server we tested it using tnsping to this Ms Sql service we created before

45 Now after successfully created service for MS SQL Server database on Oracle first node we create db link to connect with MS SQL Server database SQL> create database link con_mssql connect to "sa" identified by "oracle" using 'mssql'; In this link con_mssql -- it s a link name you can give any name here you want here we give con_mssql as a db link name connect to "sa" identified by "oracle" --- here sa it s a Ms SQL database user with whom you want to connect to and give this sa user password also 'mssql' -- mssql it s a service name which we create before using this service we can connect oracle database with ms sql server database

46 Now you can check this link successfully created Now you can insert data into ms sql server using this db link from oracle to ms sql server Before inserting row check table no any row into this emp table Insert row from oracle to ms sql server using db link

47 After inserting row you can check data into your ms sql server database row is successfully inserted You can perform select query using this syntax also from oracle database

48 Now if you have more than one MS SQL Server database and you want to connect with this database from oracle to ms sql server database. For this purpose here we create one more database at ms sql server site

49 Here we create new MS SQL Server database with name of test2

50 For this task again we have to put entry of this test2 database in ODBC using below task Go to Control Panel > Administrative Tools > Data Sources (ODBC) And click on System DSN and Click on Add tab

51

52 Select this SQL Server and click on Finish

53 Create a New Data Source to SQL Server page open Here give any name in this What name do you want to use to refer to the data source? Here we give test2mssql in name tab After that in How do you want to describe the data source? give any thing Here we give in Description tab we type tes2tmssql And in Which SQL Server do you want to connect to? tab give your host name where you install Ms Sql server 2005 here my host name its tmssql so I give tmssql in Server tab Then click on next

54

55 Here select this Change the default database to This test2 we create new database in ms sql server

56

57

58

59 After add this database in ODBC now we have to create new init.ora file on ms sql server database For that go to your DG4ODBC driver home \ hs\admin Here my path its E:\product\11.2.0\tg_1\hs\admin Go to this path and create new init.ora file just copy and past your existing init.ora file and rename it. Init<sid>.ora file here we create in this sid you can give any name for sid. Here we create new init file for this new database its name initmssqln.ora

60 In this sid name you can give any name as you want.

61 Now in this initmssqln.ora file give your new ms sql server database name you mention in this ODBC System DSN At this HS_FDS_CONNECT_INFO parameter

62 After that put entry of this your new ms sql server information into your listener.ora file on ms sql server computer where you install dg4odbc driver Go to E:\product\11.2.0\tg_1\NETWORK\ADMIN and open this listener.ora file And put this entry into your listener.ora file (SID_DESC = (SID_NAME = mssqln) (ORACLE_HOME = E:\product\11.2.0\tg_1) (PROGRAM = dg4odbc) (ENVS = "EXTPROC_DLLS=ONLY:E:\product\11.2.0\tg_1\bin\oraclsra11.dll") ) Here this sid_name its name you mention in your init<sid>.ora name. as sid name

63 After editing in listener file my listener.ora file look like this as mention below

64 After editing in listener.ora file restart the listener. If its stuck while restarting you can manually restart its service from service.msc restart its listener service from there

65 Or you can manually restart your ms sql server

66 Now after that create new service for this new database on oracle rac server on first node. Put entry in your tnsnames.ora file on oracle RAC server first node for this your new service for ms sql server. Open this your tnsnames.ora from this location C:\oracle\product\10.2.0\db_1\NETWORK

67 NWMSSQL = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = tmssql)(port = 1533)) ) (CONNECT_DATA = (SERVICE_NAME = mssqln) ) (HS = OK) ) NWMSSQL it s a service name SERVICE_NAME = mssqln its name we provide in init<sid>.ora. this mssqln its sid name we mention there in init<sid>.ora file.

68

69 After successfully create service for ms sql server on oracle database we can check it using tnsping to this nwmssql service we create for ms sql server

70 After successfully configure this new service for new ms sql server database we create new db link for this new ms sql server database using this

71 In this create database link SQL> create database link con_newms connect to "sa" identified by "oracle" using 'nwmssql'; con_newms -- it s a database link name with this link we can connect oracle database to ms sql server database "sa" identified by "oracle" it s a ms sql server database user and its password Nwmssql its s service name we create using this service name we can connect oracle database to ms sql server database. We can check this this link is successfully configured. If you want to use this db link on your another node on RAC database Here after created db link on first node you cannot use this db link on your another node on rac database. If you want to use this db link on your another node you have to create service on your another node to connect your oracle database with MS SQL Server.

72 Just open your tnsnames.ora file from your another node and put entry same as you mention on your first node. Node1 tnsnames.ora file

73

74 Now open your tnsnames.ora file on your second node and past this MS SQL Server service info in this tnsnames.ora file ******** MS SQL SERVER 2005 SERVICES ************ MSSQL = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = tmssql)(port = 1533)) ) (CONNECT_DATA = (SERVICE_NAME = mssql) ) (HS = OK) )
