Python Driver and DBI Wrapper for IBM Databases | ||
----------------------------------------------- | ||
The ibm_db driver and ibm_db_dbi wrapper provide a Python interface for IBM | ||
databases. The wrapper conforms to the DBI specification located here: | ||
http://www.python.org/dev/peps/pep-0249/ | ||
|
||
The driver and wrapper have been developed and will be supported by IBM. | ||
|
||
|
||
Python ibm_db Driver Build and Installation | ||
------------------------------------------- | ||
1. Linux | ||
|
||
Preparations (specific commands dependent on shell): | ||
If you are compiling against a DB2 instance, do the following | ||
(paths depend on system): | ||
. <path_to_sqllib>/db2profile | ||
export IBM_DB_DIR=<path_to_sqllib> | ||
export IBM_DB_LIB=<path_to_sqllib>/lib | ||
|
||
Installation Commands for Linux: | ||
python setup.py build | ||
python setup.py install | ||
|
||
2. Windows | ||
|
||
Preparations: | ||
Install Python from: | ||
http://python.org | ||
Install Visual C++ 2003, Platform SDK (latest), .NET SDK Version | ||
1.1 from: | ||
http://wiki.tcl.tk/11431 | ||
Set envrionment: | ||
CALL "C:\Program Files\Microsoft Platform SDK for Windows | ||
Server 2003 R2\SetEnv.Cmd" | ||
CALL "C:\Program Files\Microsoft Visual C++ Toolkit | ||
2003\vcvars32.bat" | ||
SET LIB=%LIB%;C:\Program Files\Microsoft Visual Studio .NET | ||
2003\Vc7\lib | ||
(Use notepad to edit config.py to your DB2 settings) | ||
set IBM_DB_DIR=<path_to_sqllib> | ||
set IBM_DB_LIB=<path_to_sqllib>\lib | ||
|
||
Installation Commands for Windows: | ||
setup.py build | ||
setup.yp install | ||
|
||
|
||
Python ibm_db_dbi Wrapper Build and Installation | ||
------------------------------------------------ | ||
There is no special build required to use the ibm_db_wrapper. However, the | ||
wrapper internally uses the driver. So the driver needs to be built and | ||
installed before you use the wrapper. | ||
|
||
|
||
Setup to use ibm_db or ibm_db_dbi | ||
--------------------------------- | ||
For Unix based systems: | ||
Depending on your shell, source the db2profile or db2chsrc. Be sure to source | ||
the profile for the DB2 instance and not the profile under the DB2 product | ||
installation. For example: | ||
. <path_to_sqllib>/db2profile | ||
or | ||
source <path_to_sqllib>/db2chsrc | ||
|
||
Import ibm_db or ibm_db_dbi inside your Python application to use the driver or | ||
wrapper functionality | ||
import ibm_db | ||
or | ||
import ibm_db_dbi | ||
|
||
Note: Please make sure that the directory containing the ibm_db_dbi.py file is | ||
added to the PYTHONPATH variable. This will ensure that the DBI wrapper can be | ||
accessed in your python applications. | ||
|
||
|
||
List of Operating Systems tested | ||
-------------------------------- | ||
SuSE Linux Server 9 32 bit | ||
Ubuntu Linux 7.04 32 bit | ||
Windows 32 bit | ||
|
||
|
||
Supported Databases | ||
------------------- | ||
IBM DB2 Database on Linux, Unix and Windows 8.2 and beyond | ||
|
||
|
||
Future Supported Databases | ||
-------------------------- | ||
IBM Cloudscape | ||
Apache Derby | ||
Remote connections to i5/OS (iSeries) | ||
Remote connections to z/OS (DB2 UDB for zOS) | ||
Informix (IDS) | ||
Native DB2 for i5/OS (iSeries) | ||
Native DB2 UDB for zOS | ||
|
||
|
||
Testing | ||
------- | ||
Tests displaying Python ibm_db driver code examples are located in the tests | ||
directory. These tests can be run by using 'python tests.py' on Unix based | ||
systems, and 'tests.py' on Windows based systems. Use vi to edit config.py to | ||
your DB2 settings. | ||
|
||
The tests that ibm_db driver uses depends on a UTF-8 database. This can be | ||
created by running: | ||
CREATE DATABASE mydatabase USING CODESET UTF-8 TERRITORY US | ||
Some of the tests utilize XML functionality only available in version 9 or | ||
later of DB2. While DB2 v8.x is fully supported, two of the tests | ||
(test_195.py and test_52949.py) utilize XML functionality. These tests will | ||
fail on version 8.x of DB2. | ||
|
||
Running the driver testsuite on Linux | ||
In order to run the entire python driver testsuite on Linux, run this | ||
command at the command prompt: | ||
python tests.py | ||
To run a single test, set the environment variable, SINGLE_PYTHON_TEST, to | ||
the test filename you would like to run, followed by the previous command. | ||
|
||
Running the driver testsuite on Windows | ||
In order to run the entire python driver testsuite on Windows, run this | ||
command at the command prompt: | ||
tests.py | ||
To run a single test, set the environment variable, SINGLE_PYTHON_TEST, to | ||
the test filename you would like to run, followed by the previous command. | ||
|
||
|
||
Known Limitations for the Python driver | ||
--------------------------------------- | ||
1. The following tests are expected to fail: | ||
test_03a.py: | ||
Fails due to an exception being thrown by the driver and not | ||
being caught by the test. | ||
test_133.py: | ||
Fails due to the None object not being returned by the | ||
ibm_db.execute() statement on line 48. | ||
test_146.py: | ||
Fails due to issues with procedures being called with | ||
parameters that have a parameter-type of SQL_PARAM_OUTPUT. | ||
test_148.py: | ||
Same issue as test_146.py. | ||
tests_53494.py: | ||
Same issue as test_52949.py. | ||
|
||
|
||
Known Limitations for the Python wrapper | ||
---------------------------------------- | ||
1. An error is thrown when selecting a row which has a BLOB type | ||
column with a null value. | ||
2. The rowcount for complex select statements can not be generated. | ||
The wrapper might throw errors with complex select statement. | ||
3. Some warnings from the drivers are not caught by the wrapper. | ||
As such these might go unnoticed. |
