Using Microsoft ODBC and Oracle Gateway

1 Installing the Driver Manager

An ODBC application makes ODBC calls to the Driver Manager. The Driver Manager carries out a number of tasks for the application such as ensuring the proper driver is loaded/unloaded. You can download the DriverManager from http://www.unixodbc.org. Here I use unixODBC-2.3.0 .

1.1Copy it to the Linux server and unzip it. 1.2Change to the unixODBC-2.3.0 directory.1.3Execute : export CPPFLAGS="-DSIZEOF_LONG_INT=8"1.4Execute : ./configure --prefix=/usr --libdir=/usr/lib64 --sysconfdir=/etc --

enable-gui=no --enable-drivers=no --enable-iconv --with-iconv-char-enc=UTF8 --with-iconv-ucode-enc=UTF16LE

1.5Execute : make

1.6Execute : make install

2 Installing Microsoft ODBC Driver for SQL Server on Linux

You can download the Microsoft ODBC Driver 11 for SQL Server on Linux from here: https://www.microsoft.com/en-us/download/details.aspx?id=36437

2.1unzip msodbcsql-11.0.2270.0.tar.gz2.2change to msodbcsql-11.0.2270.0

2.3Execute the command: ./install.sh install 2.4After reviewing the license agreement, type YES to continue with the installation.2.5To verify that the ODBC driver on Linux was registered successfully, execute the following command: odbcinst -q -d -n "ODBC Driver 11 for SQL Server".

3 installing oracle gateway

Oracle Database Gateways provide the ability to transparently integrate with non-Oracle systems from an Oracle environment. You can download it from here: http://www.oracle.com/technetwork/database/enterprise-edition/downloads/database12c-linux-download-2240591.html

3.1Unzip the binaries3.2Change to gateways3.3Execute: ./runinstaller –silent –noconfig –responseFile ./gw.rsp

3.4Execute root.sh

4 Configuring ODBC and Oracle Gateway

The configuring steps includes:

Configure ODBC DSN Configure the Gateway Initialization Parameter File Configure the Gateway Listener Configure the Database TNS descriptor Create the Database DB Links

4.1 configure /etc/odbc.ini, the /etc/odbc.ini is looks like below, where DEMO is the DSN: [DEMO]Description=Microsoft ODBC Driver 11 for SQL ServerDriver=/opt/microsoft/msodbcsql/lib64/libmsodbcsql-11.0.so.2270.0Server = 10.96.114.141Port =Language = EnglishDatabase = HUBLogging = 0LogFile =QuotedId = YesAnsiNPW = YesMars_Connection = No

4.2 verify the connectivity of the DSN by sqlcmdsqlcmd –D –S DEMO –U username

4.3 Change to $GATEWAY_HOME/hs/admin, create the initial parameters file, example:

$vi initDEMO.ora## HS init parameters#HS_FDS_CONNECT_INFO = DEMOHS_FDS_TRACE_LEVEL = debugHS_FDS_SHAREABLE_NAME = /usr/lib64/libodbc.so#HS_NLS_NCHAR = AMERICAN_AMERICA.US7ASCII#HS_LANGUAGE = AMERICAN_AMERICA.US7ASCII## ODBC specific environment variables#set ODBCINI=/etc/odbc.ini

4.4 Edit the listener.ora file and add new LISTENER for the Gateway:

LISTENER_GW = (ADDRESS_LIST= (ADDRESS=(PROTOCOL=tcp)(HOST=xxxxxxxxxxx)(PORT=1525)) )SID_LIST_LISTENER_GW= (SID_LIST= (SID_DESC= (SID_NAME=DEMO) (ORACLE_HOME=/u01/app/oracle/product/11.2.0.1/gateways) (PROGRAM=dg4odbc) ) )

4.5 Reload/restart the LISTENER for the Gateway

4.6 Edit the tnsnames.ora file to add a connect descriptor for the gateway

DEMO =

(DESCRIPTION=

(ADDRESS=(PROTOCOL=tcp)(HOST=xxxxxxxx)(PORT=1525))

(CONNECT_DATA=(SID=DEMO))

(HS=OK)

)

4.7 Create DB Link by using the TNS string you just created

SQL> create public database link dbl_demo connect to “demo” identified by “demo” using ‘demo’
