ORACLE Veri tabanından MSSQL Veri Tabanına Bağlantı (Heterogeneous Bağlantı)

Oracle veri tabanı üzerinden DBLINK mimarisini kullarak MSSQL veri tabanındaki tablolara erişim için aşağıdaki dokümanı inceleyebilirsiniz. Lütfen ilgili çalışmayı önce TEST veri tabanı üzerinde deneyiniz.

İlgili işlemin sağlanması için aşağıdaki bağlantıyı kullanarak “Microsoft® ODBC Driver 11 for SQL Server® – Red Hat Linux” paketinin indirilmesi gerekmektedir.

http://www.microsoft.com/en-us/download/confirmation.aspx?id=36437

İlgili dosya wget/upload ile oracle veri tabanının kurulu olduğu sunucu üzerine alınır.

Build unixODBC 2.3.0 DriverManager script
Copyright Microsoft Corp.

In order to use the Microsoft ODBC Driver 11 for SQL Server on Linux,
the unixODBC DriverManager must be installed on your computer.  unixODBC
DriverManager is a third-party tool made available by the unixODBC Project.
To assist you in the installation process, this script will attempt to 
download, properly configure, and build the unixODBC DriverManager from 
http://www.unixodbc.org/ for use with the Microsoft ODBC Driver 11
for SQL Server ODBC Driver on Linux.

Alternatively, you can choose to download and configure unixODBC
DriverManager from http://www.unixodbc.org/ yourself.

Note: unixODBC DriverManager is licensed to you under the terms of an
agreement between you and the unixODBC Project, not Microsoft.  Microsoft
does not guarantee the unixODBC DriverManager or grant any rights to
you.  Prior to downloading, you should review the license for unixODBC
DriverManager at http://www.unixodbc.org/.

The script is provided as a convenience to you as-is, without any express
or implied warranties of any kind.  Microsoft is not liable for any issues
arising out of your use of the script.

Enter 'YES' to have this script continue: YES

Run the command 'cd /tmp/unixODBC.26962.10505.13318/unixODBC-2.3.0; make install' to install the driver manager.

PLEASE NOTE THAT THIS WILL POTENTIALLY INSTALL THE NEW DRIVER MANAGER OVER ANY
EXISTING UNIXODBC DRIVER MANAGER.  IF YOU HAVE ANOTHER COPY OF UNIXODBC INSTALLED,
THIS MAY POTENTIALLY OVERWRITE THAT COPY.

Paket kurulumu tamamlandıktan sonra ilgili paketlerin oluşturduğu .ini ve config bilgilerine erişim için bazı komutlar çalıştıracağız.

Paketin version bilgisine erişmek için;

[root@db msodbcsql-11.0.2270.0]# odbc_config --version
2.3.0

Yapılandırma bilgilerine erişim. /etc/odbc.ini en çok kullanacağımız yapılandırma dosya olacak.

[root@TestOracle01 msodbcsql-11.0.2270.0]# odbcinst -j
unixODBC 2.3.0

FILE DATA SOURCES..: /etc/ODBCDataSources
USER DATA SOURCES..: /root/.odbc.ini

SQLLEN Size........: 8

Driver bilgilerine erişim;

[root@db msodbcsql-11.0.2270.0]# odbcinst -q -d -n "ODBC Driver 11 for SQL Server"

Bu kontroller sonrası ilgili paketleri artık Oracle’dan MSSQL’e bağlantı yapmak için kullanabiliriz.

MSSQL Bağlantı Bilgilerinin Yapılandırılması

Bağlantı yapılacak MSSQL veri tabanına ait bilgileri /etc/odbc.ini dosyasına işlememiz gerekiyor.

Burada dikkat edilmesi gereken nokta, [ODBC Data Sources] altına eklediğimiz veri tabanının türünü belirtmelidir. Eğer birden fazla kullanılacaksa yeni satıra işlenmesi gerekiyor.

[MSSQL_DB_NAME] > şeklinde tanımladığımız MSSQL veri tabanına hangi bilgiler ile erişimin sağlanacağı.

[root@mhrstestdb2 ~]# cat /etc/odbc.ini 
[ODBC Data Sources]
MSSQL_DB_NAME=MS SQL Server

[MSSQL_DB_NAME]
Driver=/opt/microsoft/msodbcsql/lib64/libmsodbcsql-11.0.so.2270.0
Description=Microsoft ODBC Driver 11 for SQL Server
Server=tcp:<IP_ADRESI>,<PORT>
Database=<DB_NAME>
User=username
Password=password
QuotedId=YES
AnsiNPW=YES
Threading=1
UsageCount=1
AutoTranslate=No

Yukarıda örnek bir odbc.ini dosyasının görüntüsünü görüyorsunuz.

[MSSQL_DB_NAME] tanımlamasının ORACLE tarafından anlamlı olması için aşağıdaki işlemleri yapacağız.

[root@db ~]# su - oracle
[oracle@db ~]$ cd /u01/app/oracle/product/11.2.0.4/db_1/hs/admin/
[oracle@db admin]$ ls -ltr
total 12
-rw-r--r-- 1 oracle oinstall  489 Aug 24  2013 initdg4odbc.ora
-rw-r--r-- 1 oracle oinstall 1109 Aug 24  2013 extproc.ora

Dizini altına MSSQL_DB_NAME in ORACLE tarafından tanınması için, buradaki kritik nokta .ora dosyasının adı .ini dosyasında yaptığınız tanımlama ile aynı olmalı ve init… ile başlamalıdır.

[oracle@mhrstestdb2 admin]$ vi init<MSSQL_DB_NAME>.ora 
HS_FDS_CONNECT_INFO = MSSQL_DB_NAME
HS_FDS_SHAREABLE_NAME = /usr/lib64/libodbc.so
HS_FDS_TRACE_LEVEL = 0
HS_LANGUAGE = AMERICAN_AMERICA.WE8MSWIN1252
HS_KEEP_REMOTE_COLUMN_SIZE = LOCAL
HS_NLS_LENGTH_SEMANTICS = CHAR
HS_NLS_NCHAR = UCS2

Enviroment tarafından bu odbc.ini dosyasına erişim için,

set ODBCINI=/etc/odbc.ini

Eğer tüm adımlar doğru ise isql aracı ile MSSQL veri tabanına bağlantı sağlayabilir durumda olacağız. NOT: Password tek tırnak (‘) içerisinde yazılmalı. Eğer password’de tek tırnak varsa problem yaşanıyor.

[oracle@db ~]$ isql -v <MSSQL_DB_NAME> <USERNAME> <PASSWORD>
+---------------------------------------+
| Connected!                            |
|                                       |
| sql-statement                         |
| help [tablename]                      |
| quit                                  |
|                                       |
+---------------------------------------+

Buraya kadar bir sorun yaşamadıysanız ORACLE’ın bu hizmete DBLINK üzerinden erişmesini sağlayalım.

[oracle@db admin]$ cd /u01/app/oracle/product/11.2.0.4/db_1/network/admin

<MSSQL_DB_NAME> =
   (DESCRIPTION =
      (ADDRESS =
         (PROTOCOL = tcp)
         (HOST = <oracle veri tabanının host bilgisi> )
         (PORT = 1521))
      (CONNECT_DATA =
         (SID = <MSSQL_DB_NAME> ))
      (HS = OK)
   )

MSSQL için yaptığımız yapılandırmayı sanki ORACLE tarafından sunulan bir hizmetmiş gibi gösteriyoruz.

[oracle@db admin]$ cd /u01/app/11.2.0.4/grid/network/admin

MSSQL_DB_NAME =
   (DESCRIPTION =
      (ADDRESS =
         (PROTOCOL = tcp)
         (HOST = <oracle veri tabanının host bilgisi>)
         (PORT = 1521))
      (CONNECT_DATA =
         (SID = <MSSQL_DB_NAME>))
      (HS = OK)
   )

NOT: RAC mimarisinde Oracle veri tabanı kullanıyorsanız ilgili işlem her NODE üzerinde sağlanmalıdır.

İlgili bilgiler girildikten sonra LISTENER tanımı yapılması gerekmektedir.

SID_LIST_LISTENER =
   (SID_LIST =
      (SID_DESC =
         (SID_NAME = <MSSQL_DB_NAME>)
         (ORACLE_HOME = /u01/app/oracle/product/11.2.0.4/db_1)
         (PROGRAM = /u01/app/oracle/product/11.2.0.4/db_1/bin/dg4odbc)
         (ENVS=LD_LIBRARY_PATH=/opt/microsoft/msodbcsql/lib64/libmsodbcsql-11.0.so.2270.0:/usr/lib64:/u01/app/oracle/product/11.2.0.4/db_1/lib)
      )
   )

LD_LIBRARY_PATH bilgisini daha önce paket kurulumu sırasında öğrenmiştik.

Oracle veri tabanı üzerinde DBLINK tanımı yapalı.

CREATE PUBLIC DATABASE LINK <MSSQL_DB_NAME>
 CONNECT TO <USERNAME>
 IDENTIFIED BY <PASSWORD>
 USING '<MSSQL_DB_NAME';

USING kısmı odbc.ini’de tanımladığımız servis adını kullanacağız.

SELECT SYSDATE FROM DUAL@<MSSQL_DB_NAME;

İlgili sonucun görüntülenmesiyle Oracle’dan MSSQL’e erişim sağlanacaktır. Dikkat edilmesi gereken en önemli kısmın servis isimlendirmeleri ve erişim isimlendirmeleri olduğunu lütfen unutmayınız.
