How To Install and Configure the Multi-Tier Edition JDBC Drivers for Informix (Windows)

Server Components

Installation (Request Broker and Database Agent)

  1. Our Enterprise Edition (Multi-Tier) server components installers for Windows are distributed as .msi files. You need to download one Enterprise Edition Request Broker installer (ntbrzzzz.msi for all 32-bit processor architectures, wabrzzzz.msi for x86_64, or wibrzzzz.msi for IA_64) and at least one Agent installer (same architecture) for the specific target data source(s). Double-click on the downloaded request broker .MSI file to start the installation.
  2. The Request Broker installers will specifically prompt for the location of a local license file.

    Note: Agent installers do not, as their licensing is handled through the Broker.
  3. Click the "Browse" button to locate a license file on your Windows machine.
  4. Check the "I don't want to install a license file" box if you do not have one.
  5. Once Completed, run the Database agent installation by clicking on the downloaded .MSI file.
  6. The Request Broker can be started and stopped by locating the OpenLink Request Broker service in the Services panel, or by using the toolbar service shortcut provided after installation.
  7. Installation is complete, proceed to making a test connection with your Client Component installation. If you haven't installed this component, please follow one of the following
Non-Advanced Users should proceed to the Client Components installation and configuration guides

  1. Informix requires a small amount of additional environmental configuration in the OpenLink Request Broker session rule book (c:\Program Files\OpenLink Software\UDA\bin\oplrqb.ini)

    • Open the file c:\Program Files\OpenLink Software\UDA\bin\oplrqb.ini with a suitable text editor, such as Wordpad.

    • Locate and edit the [Environment xxxxx] section (where xxxxx matches your target database), and ensure that any relevant environment variables pertaining to your system and target database are correct.

      NOTE: You may need to consult with your database administrator to verify these. The following example depicts an environment section for Informix --

      [Environment INFORMIX2000]
INFORMIXSERVER        = your_informix_server
INFORMIXDIR           = C:\Program Files\IBM\Informix\Client-SDK
DELIMIDENT            = Y      ; Allow quoted identifiers
OPL_INF_MULTISESS     = Y      ; Allow multiple sessions
OPL_SPACEPADCHAR      = Y      ; Pad CHAR fields with spaces
CURSOR_SENSITIVITY    = LOW    ; Set to HIGH after loading oplrvc.sql
;FET_BUF_SIZE          = 65535  ; Size of the fetch buffer
;FORCE_ONLINE_DATABASE = 1      ; Force mode to (0) SE or (1) ONLINE
;CLIENT_LOCALE         = EN_US.UTF8  ; Uncomment and adjust when Client and Server locale settings differ
Path                  = C:\Program Files\IBM\Informix\Client-SDK\bin  ; Find shared libraries

Configuration

  1. The OpenLink installer should set your CLASSPATH. You should have a pre-existing JAVA_HOME directory that points to the root of your Java installation; this same directory should also be included in your PATH. No further configuration should be needed.
  2. Driver Name: opljdbc.jar, opljdbc2.jar, opljdbc3.jar, megathin.jar, megathin2.jar, megathin3.jar
    Driver Class Name: openlink.jdbc.Driver, openlink.jdbc2.Driver, openlink.jdbc3.Driver
    Connection URL: 
    jdbc:openlink://<Hostname>:[portnumber] [/UID] [/PWD] [/READONLY] [/SVT]
[/APPLICATION] [/FBS|FETCHBUFFERSIZE] [/ENCRYPTED] [/CHARSET] [/UNICODE]
[/DLF] [/DATABASE] [/OPTIONS] [/DRIVER]

    • Hostname - DNS-resolvable hostname or IP address of the machine that runs an OpenLink Request Broker instance.
    • Port Number - TCP port on which the Request Broker listens.
    • /UID - Database username.
    • /PWD - Database password.
    • /READONLY - Read-write or read-only session mode.
    • /SVT - A valid domain alias from the [Domain Aliases] section of the OpenLink server component's oplrqb.ini file. Default domain aliases represent the type of database agent to which the application intends to connect, e.g., DB2, Informix 2000, Oracle 8.1.x. Custom aliases may be any string.
    • /APPLICATION - The Application name. Enables connectivity when restrictive server-side rules screen by application name.
    • /FBS - (also /FETCHBUFFERSIZE) The number of rows to return during one fetch operation.
    • /ENCRYPTED - Encrypt outgoing OpenLink communications packets. Disabled by default. Enabled with '1', 'Y', 'y'; disabled with '0', 'N', 'n'.
    • /CHARSET - The charset of remote databases. The default value is read from System.getProperty("file.encoding").
    • /UNICODE - Enables a Unicode connection. Disabled by default. Enabled with '1', 'Y', 'y'; disabled with '0', 'N', 'n'.
    • /DLF - Defers large data fields (BLOB, CLOB, etc.) to the end of the resultset. Smaller data types are retrieved first. This enhances performance. Disabled by default. Enabled with '1', 'Y', 'y'; disabled with '0', 'N', 'n'.
    • /DATABASE - Actual database name within a particular database environment.
    • /OPTIONS - Optional connection attribute passes specialized database-native client connection parameters, such as Progress socket parameters, Oracle SQL*Net Service Names, Ingres vnodes, remote Informix instance names, or DB2 remote database aliases. Not necessary when ConnectOptions are set in the Broker Rulebook.
    • /DRIVER - An ODBC Driver name wrapped in braces ("{}"). Used for DSN-Less connections to remote ODBC Drivers.
