3 Integration of Tibero and Python 1. Checking the Basic Environment 1.1. Python Version ~]# Python Python (#1, Feb , 16:05:45) [GCC (Red Hat )] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> 1.2. gcc Version ~]# gcc v Using built-in specs. Target: x86_64-redhat-linux Configured with:../configure --prefix=/usr --mandir=/usr/share/man -- infodir=/usr/share/info --enable-shared --enable-threads=posix --enablechecking=release --with-system-zlib --enable- cxa_atexit --disable-libunwindexceptions --enable-libgcj-multifile --enable-languages=c,c++,objc,objc++,java,fortran,ada --enable-java-awt=gtk --disable-dssi --disable-plugin --withjava-home=/usr/lib/jvm/java gcj /jre --with-cpu=generic --host=x86_64- redhat-linux Thread model: posix gcc version (Red Hat ) 1.3. Checking Tibero The following is an example of verifying that a Tibero server or a Tibero client is installed correctly in Python. # ps -ef grep tbsvr Or # cd / # find./ -name "libtbodbc.so" 2. Installing a Basic Package 2.1. Python-devel A developer package is necessary to compile pyodbc. Use yum to install the package. [root@tiberovm ~]# yum install Python-devel Loaded plugins: fastestmirror, security Loading mirror speeds from cached hostfile * base: ftp.iij.ad.jp * extras: ftp.iij.ad.jp * updates: ftp.iij.ad.jp Setting up Install Process Resolving Dependencies 3

4 ... Complete! 2.2. unixodbc-devel ~]# yum install unixodbc-devel Loaded plugins: fastestmirror, security Loading mirror speeds from cached hostfile * base: ftp.iij.ad.jp * extras: ftp.iij.ad.jp * updates: ftp.iij.ad.jp Setting up Install Process Resolving Dependencies... Complete! 3. Installing pyodbc 3.1. Reference USR Category pyodbc download Python download Python development Details Points to Consider When Installing pyodbc An error occurs in Python when pyodbc is installed. To ensure Python is compiled successfully, reinstallation is necessary with pyodbc versions 2.6.x and higher and with Python 3.x and earlier. [root@tiberovm pyodbc-3.0.7]# Python setup.py build... gcc -pthread -fno-strict-aliasing -DNDEBUG -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64 -mtune=generic - D_GNU_SOURCE -fpic -fpic -DPYODBC_VERSION= I/usr/include/Python2.4 -c /tmp/pyodbc-3.0.7/src/pyodbcmodule.cpp -o build/temp.linux-x86_64-2.4/tmp/pyodbc /src/pyodbcmodule.o -Wno-write-strings /tmp/pyodbc-3.0.7/src/connection.h:27: error: 'uintptr_t' does not name a type error: command 'gcc' failed with exit status 1... gcc -pthread -fno-strict-aliasing -DNDEBUG -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64 -mtune=generic - D_GNU_SOURCE -fpic -fpic -DPYODBC_VERSION= I/usr/include/Python2.4 -c /tmp/pyodbc-3.0.7/src/cursor.cpp -o build/temp.linux-x86_64-2.4/tmp/pyodbc /src/cursor.o -Wno-write-strings /tmp/pyodbc-3.0.7/src/cursor.cpp:2153: error: invalid conversion from 'const char*' to 'char*' error: command 'gcc' failed with exit status 1 4

5 3.3. Reinstalling Python Check the Python installation. # which Python /usr/bin/python Install Python version # cd /tmp # tar -xvf Python tar # cd Python #./ configure # make # make install Link to the Python newly installed in /usr/bin. # ln -s /tmp/python-2.7.5/python /usr/bin/python [root@tiberovm bin]# Python Python (default, Oct , 22:12:16) [GCC (Red Hat )] on linux2 Type "help", "copyright", "credits" or "license" for more information. >> 4. Installing pyodbc and Configuring the ODBC Environment Unzip pyodbc and go to the source directory to install pyodbc. # cd /tmp/pyodbc [root@tiberovm pyodbc-3.0.7]# Python setup.py build [root@tiberovm pyodbc-3.0.7]# Python setup.py install 4.1. Check that pyodbc is Operating Normally If pyodbc is not installed correctly, an error occurs when importing it. If pyodbc is running normally, no message is displayed. [root@tiberovm pyodbc-3.0.7]# Python Python (default, Oct , 22:12:16) [GCC (Red Hat )] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import pyodbc 5

6 4.2. Configuring DSN Specify the following information in /etc/odbc.ini and /root/.odbc.ini. A DSN is configured in /etc/odbc.ini by default. However, if DSN fails, also configure /etc/odbc.ini. [ODBC Data Sources] tibero5 = Tibero5 ODBC driver [ODBC] Trace = 1 TraceFile = /tmp/odbc.trace [tibero5] Driver = /home/tibero/tibero5/client/lib/libtbodbc.so Description = Tibero5 ODBC Datasource SID = tibero User = tibero Password = tmax 4.3. Applying Tibero Environment Variables Find the Tibero server or Tibero client account installed on the Python development server, and apply Tibero environment variables of.bash_profile to.bash_profile of the root. ### Tibero RDBMS 5 ENV ### export TB_HOME=/home/tibero/tibero5 export TB_SID=tibero export TB_PROF_DIR=$TB_HOME/bin/prof export PATH=.:$TB_HOME/bin:$TB_HOME/client/bin:$PATH export LD_LIBRARY_PATH=$TB_HOME/lib:$TB_HOME/client/lib:$LD_LIBRARY_PATH 4.4. DNS Connection Test [root@tiberovm py_test]# isql -v tibero Connected! sql-statement help [tablename] quit SQL> select * from dual; DUMMY X SQLRowCount returns 1 1 rows fetched 6

7 5. Python Test 5.1. Example py_test]# vi test2.py # -*- coding: cp949 -*- import pyodbc db = pyodbc.connect('dsn=tibero5;uid=tibero;pwd=tmax') cursor = db.cursor() cursor.execute('select * from test1') data = cursor.fetchall() for x in data: print (x[0]) cursor.close() db.close() 5.2. Execution If the output displays a broken Korean letter, set "export TB_NLS_LANG=UTF8". [root@tiberovm py_test]# Python test2.py AAA?± 浿 export TB_NLS_LANG=UTF8 [root@tiberovm py_test]# Python test2.py AAA 홍길동 7
