]]> https://youthdev.net/en/vi-sao-doanh-nghiep-can-mot-he-thong-erp-quan-ly-toan-dien/feed/ 0 Connect Oracle database on Eclipse Linux using OCCI https://youthdev.net/en/connect-oracle-database-on-eclipse-linux-using-occi/ https://youthdev.net/en/connect-oracle-database-on-eclipse-linux-using-occi/#comments Mon, 27 Apr 2015 02:09:15 +0000 http://youthdev.net/?p=4312 To develop database application that use Oracle. Of course with Oracle database installed, programer must prepaire two packages provided by Oracle. One use to provide share library (*.so files) for application to run under Linux, another one is provide class header (*.h files) that programer can include in their application. We could download that two packages at http://www.oracle.com/technetwork/database/features/instant-client/index-097480.html, it’s called Instant Client.

I’m using CentOS 6.2 64 bit, so I will download Instant Client for Linux x86-64, there any many packages, however, only two package we need:

  1. Instant Client Package – Basic: All files required to run OCI, OCCI, and JDBC-OCI applications.
  2. *Instant Client Package – Basic Lite: Smaller version of the Basic, with only English error messages and Unicode, ASCII, and Western European character set support.
  3. *Instant Client Package – SDK: Additional header files and an example makefile for developing Oracle applications with Instant Client.

The first and second is the same, Basic Lite is smaller than Basic with fewer language support. Everyone need to choose between one of them. In my opinion, I install the first and the last packages.

  • Instant Client Package – Basic for Linux 64 bit provide share library at /usr/lib/oracle/11.2/client64/lib, this is required libraries to run OCCI program.
  • Instance Client Package – SDK for Linux 64 bit provide additional header files at /usr/include/oracle/11.2/client64, this is c++ header files that we need to include in our program.

Next step, we must tell Eclipse the path to the share libraries and the header files by: on Eclipse top menu, go to Project/Properties/C++ General/Path and Symbols

Add Oracle OCCI header files and libraries into eclipse
Eclipse Path and Symbols properties.

To-do list:

  • Add header files directory into Include tab.
    (Add /usr/include/oracle/11.2/client64 into GNU C++)
  • Add libraries directory into Library Path tab.
    (Add /usr/lib/oracle/11.2/client64/lib)
  • Tell Eclipse which library that you want to link with your application by add needed libraries name into Libraries tab.
    In my situation, I need to add nnz11 (libnnz11.so in libraries directory), clntsh (libclntsh.so), occi (libocci.so).

Add OCCI libraries to Eclipse
Required OCCI libraries

We need only occi library but nnz11 and clntsh is required by occi, so we need to add them first. If not, Console may be throw an error the same as:

Console
  1. Invoking: GCC C++ Linker
  2. g++ -L”/media/Data/workspace/zie/lib/curl/lib” -L/usr/lib/oracle/11.2/client64/lib -o”zie”  ./src/zie.o  ./src/db/db.o   -locci
  3. /usr/lib/oracle/11.2/client64/lib/libocci.so: undefined reference to `OCISubscriptionDisable’
  4. /usr/lib/oracle/11.2/client64/lib/libocci.so: undefined reference to `ldxend’
  5. /usr/lib/oracle/11.2/client64/lib/libocci.so: undefined reference to `OCIPConvertRowidToUb1′
  6. …

Hide/show line number

Additional, we need to set enviroment LD_LIBRARY_PATH = /usr/lib/oracle/11.2/client64/lib. It’s important to let our library know another. We can set this environment by append two line into ~/.bash_profile file (you may need to logout and relogin after changing this file):

  1. LD_LIBRARY_PATH = /usr/lib/oracle/11.2/client64/lib
  2. export LD_LIBRARY_PATH

Hide/show line number

Remember, libraries is require to run our application and header file is require for development. If we have already finish all steps, we can create a demo project that connect to oracle database.

demo.cpp
  1. #include
  2. #include “occi.h”
  3. #include
  5. using namespace std;
  6. using namespace oracle::occi;
  8. int main() {
  9.         //Create new environment
  10.         Environment *env = Environment::createEnvironment(Environment::DEFAULT);
  11.         Connection *conn = NULL;
  13.         try {
  14.                 string user     = “username”;
  15.                 string passwd   = “password”;
  16.                 string host     = “localhost”;
  17.                 //Create new connection
  18.                 conn = env->createConnection(user, passwd, host);
  19.         }
  20.         catch(SQLException &e) {
  21.                 cout << e.getMessage();
  22.         }
  24.         try {
  25.                 Statement *stmt = conn->createStatement(“SELECT * FROM my_table”);
  26.                 stmt->setPrefetchRowCount(32);
  27.                 ResultSet *rs = stmt->executeQuery();
  28.                 while(rs->next()) {
  29.                         cout << rs->getString(2) << endl;
  30.                 }
  31.         }
  32.         catch(SQLException &e) {
  34.         }
  35.         return 0;
  36. }

Hide/show line number

If build successfully, we can sure that adding libraries and header step are ok. This demo project will execute query “SELECT * FROOM my_table”.

Hope that help!

It you are doing some update but no changing, try to disable Magento cache at System/Cache Management.
All magento extension should be place in /app/code/community. In /app/code you also see core folder, sometime may be local folder which is created by other extension. The community or local called Code Pool.

Begining, we create our extension folder structure, if my company named Bb, and my extension name is Product, I will create the folder structure /app/code/community/Bb/Product. It’s mean our extension stay in community Code Pool and our extension is Bb_Product.

Store your extension information in /app/code/community/Bb/Product/etc/config.xml. The simple extension config file may be follow:

config.xml
  2. <config>
  3.     <modules>
  4.         <bb_product>
  5.             <version>1.0>
  6.         >
  7.     >
  8. >

Hide/show line number

Now, our extension has it own profile, to let Magento load and control your extension, you must tell it “Heyx, load my extension please, my extension is Bb_Product in community Code Pool!”, so just create /app/code/etc/modules/Bb_Product.xml file:

Bb_Product.xml
  2. <config>
  3.     <modules>
  4.         <Bb_Product>
  5.             <active>true>
  6.             <codePool>community>
  7.         >
  8.     >
  9. >

Hide/show line number

That enough, our extension now can be loaded by Magento and you can enable or disable our extension in Admin Control Panel at System/Configuration/Advanced.

The next mission is create a page that output “Hello world”. Magento is base on Zend, so Magento is MVC base. If you don’t know anything about MVC, you should try to understand it first!

Create IndexControler.php file in /app/code/community/Bb/Product/controllers (offcourse, create /app/code/community/Bb/Product/controllers first)

IndexController.php

Hide/show line number

Tell Magento know when should it use our controller, append some code into /app/code/community/Bb/Product/etc/config.xml.

config.xml
  2. <config>
  3.     <modules>
  4.         <Bb_Product>
  5.             <version>1.0>
  6.         >
  7.     >
  8.     <frontend>
  9.         <routers>
  10.                 <bbproduct>
  11.                         <use>standard>
  12.                         <args>
  13.                                 <module>Bb_Product>
  14.                                 <frontName>bbproduct>
  15.                         >
  16.                 >
  17.         >
  18.     >
  19. >

Hide/show line number

You have already created Hello world magento extension. Visit our extension at:

  • http://yourdomain.com/index.php/bbproduct/index/index (it is the same with http://yourdomain.com/index.php/bbproduct/index or http://yourdomain.com/index.php/bbproduct).
    You should see “Hello world” text.
  • http://yourdomain.com/index.php/bbproduct/index/myaction.
    This output “Hello world, this is myaction”
  • http://yourdomain.com/index.php/bbproduct/index/myaction2
    This action will output default Magento page template.
