Connecting with DB2 Generic ODBC

In Scriptcase, we have the following drivers available for connection to DB2: DB2 PDO ODBC, PDO IBM, DB2, DB2 Native ODBC, DB2 ODBC Generic and DB2 ODBC Generic 6 or Below. If you are using your own, pre-configured environment, DB2 extensions must be manually enabled in PHP.

Prerequisites

Before proceeding with this documentation, check your PHP architecture. In order for drivers to be enabled correctly, files must be downloaded according to the used architecture.

  • In your Scriptcase, there is the file info.php, access it by the URL: http://127.0.0.1:8091/scriptcase/info.php, where you will find the information regarding the architecture in phpinfo().

NOTE: If you are using Scriptcase’s automatic installer, the PHP architecture will be the same as the one you downloaded. Download the IBM Data Server Runtime Client according to your PHP architecture.

PHP Architecture

  • Architecture x86 = 32 bits
  • Architecture x64 = 64 bits

Listed below are the files required for DB2 drivers to be enabled.

Required files:

x64

  • IBM Data Server Runtime Client 11.5(x64): Click here

x86

  • IBM Data Server Runtime Client 11.5(x86): Click here

Other Files

  • PHP extensions (PDO_IBM and IBM_DB2): Click here

Configuring DB2 Generic ODBC on Windows

Before installing the IBM Data Server Runtime Client, you need to enable the extensions in PHP for Scriptcase to recognize the DB2 connection drivers. Follow them steps below to correctly enable all drivers in Scriptcase.

IMPORTANT: If you are using Scriptcase’s automatic installer, the extensions are already enabled in PHP, requiring only the installation of the client. Proceed to item 3.

1 - Extract the .zip file and copy the downloaded pdo_ibm and ibm_db2 .dll extension files previously to your PHP ext folder.

2 - In the php.ini file, located in C:\php, add the lines referring to the DB2 extensions pdo_ibm and ibm_db2. See the example below:

extension=ibm_db2
extension=pdo_ibm

Enabling DB2 extensions

3 - After downloading, follow the installation wizard by clicking on next, keeping the default values of the installer.

Creating the DSN for connection

To connect to the DB2 Generic ODBC Driver, you need to manually create a DataSource Name in the DB2 files. Follow the steps described below to perform this configuration.

ATTENTION: The ODBC must be created on the same server where Scriptcase is installed.

1 - Access your ODBC Data Source Manager and select according to your architecture. We will select the x64 version:

ODBC Data Source Manager

2 - When entering the ODBC Data Sources Administrator, select the DSN System tab and click Add to create your connection to your Access Database.

Creating DSN

3 - After that, it is necessary to select the Driver to connect to DB2. Select the Driver: IBM DB2 ODBC DRIVER.

Selecting ODBC Driver

4 - Now, you need to define the DSN name and the Database alias.

Naming DSN

  • Data Source Name: Enter the name that the DSN will have so that you can use it in Scriptcase.

  • Database alias: Include and enter the name of the database you will connect to.

  • Description: Add a description for the DSN.

4.1 - After entering the name and description, click the button. After informing the name and description, click the Include button.

DSN credentials

  • User ID: Inform the user to authenticate with the DB2 database.

  • Password: Enter the corresponding password to authenticate with the informed user.

  • Save Password: By checking this option, the password is stored for future authentications and connection tests.

4.2 - Now, to configure the database, click on the TCP/IP tab.

DSN Database

  • Database Name: Inform the database that you will connect to.

  • Database alias: Enter the database alias, if the database has one. If not, use the same name as the database.

  • Hostname: Enter the IP or domain of the server where the DB2 database is installed.

  • Port Number: Enter the port for connection. By default, DB2 banks use port 50000.

To finish, click on OK.

Creating a Connection in Scriptcase

See below how to create a connection in your Scriptcase project, using the enabled Driver and the DB2 database.

1 - Access a project from your Scriptcase.

2 - Click the New Connection icon to create a connection

Creating a new connection

or access the Database > New connection menu.

Creating a new connection

After that, a screen will appear with all database connections.

3 - Select the DB2 connection.

Selecting the database connection

Connection

Enter the parameters for connecting to your database as follows:

Connecting to the database

  • Connection name: Define the name of your new connection. By default, Scriptcase adds the prefix conn along with the database name.

  • DBMS Driver: Select the Driver for connection. In this example, we use the DB2 ODBC Genérico driver.

  • Server/Host (Name or IP): Enter the System DSN created in the ODBC Data Source.
  • EX: db2

  • Schema: Inform the Scheme of specific tables created for the use of the informed user.
    • This item is optional if you do not have a schema configured in your database .
  • Username: Inform the user to authenticate the connection to your database.

  • Password: Enter the password to complete the authentication process.

  • Test connection: Click this button to get a response to the Scriptcase request to find out if the parameters entered are correct.

Testing the database connection

Filter

Accessing this tab, you can configure which Database items will be displayed on the connection, depending on the owner or not.

Filtering the database connection

Show


It allows the connection to see tables, views, system tables and procedures depending on the items selected by the user. By default, the items Tables and Views are already selected by Scriptcase.

  • Tables: Selecting this option, the tables in your database will be displayed.
    • By default, Scriptcase enables this option .
  • Views: By selecting this option, the views of your database will be displayed.
    • By default, Scriptcase enables this option .
  • System Tables: Selecting this option, the system tables of your database will be displayed.

  • Procedures: By selecting this option, the procedures of your database will be displayed.

Searches


Allows you to define which tables and owners are displayed.

  • Tables: You can define in this option which tables will be displayed. The configuration can contain a PREFIX%% or name of the tables to display.
    • By default, Scriptcase leaves this option empty .
    • EX:

    Example of using the prefix


  • Owner: Inform the user who sees the tables informed for display.
    • User must be capitalized as in the example above .
  • View: Choose whether tables for the informed owner are displayed.

NOTE: By using table filtering, you eliminate unnecessary tables for your project and improves the performance of your database connection.

Advanced

In this tab, you have access to specific settings for the connection. The settings made in this session impact the data display and application performance.

Advanced database connection configuration

  • client_encoding: Select the encoding used in your database. In the example above, we use client_encoding UTF-8.
    • By default, this option is left blank by Scriptcase .
  • Decimal Separator: Select the type of separator for decimal records, between comma and period.
    • By default, the . dot is selected as a separator .
  • Persistent Connection: Define whether connections will be closed after the execution of your scripts in Scriptcase applications.
    • By default, Scriptcase disables this option .
  • Use the schema before the table name: Define whether the database schema will be displayed before the table names.
    • By default, Scriptcase enables this option .
