Introduction

Introduced as part of DB2 Connect™ Version 9.5 Fix Pack 3, the IBM Data Server Driver Package (ds driver) is the best way to get runtime support for applications that need to interact directly with a database without having to actually build the applications with ODBC or CLI APIs. The big advantage of the IBM Data Server Driver Package is its small footprint compared with the IBM Data Server Runtime Client or the IBM Data Server Client. The IBM Data Server Driver Package is designed to be redistributed by Independent Software Vendors (ISVs) and to be used for application distribution in mass deployment scenarios in typically large enterprise database environments.

The IBM Data Server Driver Package provides support for applications developed using the following APIs using application-specific drivers:

• ODBC, CLI, SQLJ, and JDBC
• Open source drivers Ruby, Python, PHP, and Perl
• Windows-platform drivers .NET Provider (.NET) and OLE DB Provider (OLE DB)

By using the IBM Data Server Driver Package, applications can use any of these protocols to perform database operations, without having to rely on the IBM Data Server Runtime Client or the IBM Data Server Client. The IBM Data Server Driver Package can also be used in conjunction with many user-friendly tools and command line utilities, such as CLPPlus.

Figure 1 shows that multiple applications using the application-specific drivers that are shipped as part of the IBM Data Server Driver Package can communicate with various IBM databases.

The lists describe the platforms and languages supported in DB2 V9.7. See Resources to determine which platforms or languages are supported in subsequent versions of DB2.

Informix support

The IBM Data Server Driver Package supports .NET, Perl, PHP, Python, Ruby, and ODBC application development for Informix databases. .NET is an important interface for developing applications to the Informix database. For more information, see the article Get started with the IBM Data Server CLI Driver for Informix (developerWorks, Dec 2010) in the Resources section.

Understanding the advantages of using the IBM Data Server Driver Package

Following are some of the reasons to use the IBM Data Server Driver Package over another driver. The IBM Data Server Driver Package:

• Is easier to download and install.
• Is easier to deploy because of its small footprint.
• Requires fewer packages to bind to the server, and the packages have not changed since DB2 V8. This is a key factor for DB2 Connect customers.
• Is easier to upgrade. In order to upgrade the IBM Data Server Runtime Client or the IBM Data Server Client, you need to plan ahead because of the larger sizes and space requirements. Because IBM Data Server Driver Package occupies less space, upgrades are easy.
• Can be conveniently redistributed by independent software vendors (ISVs).
• Can be used for application distribution in large-scale deployment scenarios.

Understanding the limitations of the IBM Data Server Driver Package

When evaluating which solution to select for runtime support, you should be aware of the following limitations of the IBM Data Server Driver Package:

• DB2 Command Line Processor (CLP) functionality is not supported.
• Cataloging is not supported.
• CLIENT type authentication is not supported.
• There is no local database directory. Lightweight Directory Access Protocol (LDAP) cache is not saved to disk.

In order to bind packages, db2bind cannot be used in IBM Data Server Driver Package. To overcome this limitation, jcc.DB2Binder can be used. See Resources for more information about jcc.DB2Binder.

Introducing the IBM Data Server Driver Package components

The IBM Data Server Driver Package consists of ODBC/CLI, .NET, OLE DB, Open source, SQLJ, and JDBC driver components. The following sections describe how these components use the configuration files. The tools, utilities, and diagnostic support these components provide are also described.

Configuration files

The IBM Data Server Driver Package uses three different configuration files:

• db2cli.ini
• db2dsdriver.cfg
• DB2JccConfiguration.properties

With the exception of JDBC and SQLJ, these configuration files are used by the drivers available in the IBM Data Server Driver Package. Table 2 shows the configuration files that are applicable to the available drivers.

The open source drivers expose their attributes at the scripting language or framework level so that the db2cli.ini and db2dsdriver.cfg configuration files are transparent to the application developer. The db2dsdriver.cfg file is the default configuration file used by .NET. Consequently, .NET is not affected by settings in the db2cli.ini file. JDBC and SQLJ configuration properties can be set in a resource named DB2JccConfiguration.properties. See Resources to learn how configuration properties can be set in other ways.

Table 3 shows where the configuration files used by the IBM Data Server Driver Package are typically stored.

INSTALL-DIR

Represents the installation path where the IBM Data Server Driver Package is installed. On Linux and UNIX platforms, the installation path is typically the path where the IBM Data Server Driver Package was unzipped, such as /home/db2inst1/dsdriver. On Windows, the installation path is the directory specified during installation.

COPY_NAME

Represents the copy name specified during the IBM Data Server Driver Package installation for the Windows platform only.

A closer look at the db2cli.ini configuration file

The db2cli.ini configuration file is a text-based file that consists of keywords and values. The keywords used can be initialized for a particular data source name (DSN). The driver reads all keywords under a specific DSN before connecting to that data source. This file also has a COMMON section, which contains keywords that the driver reads regardless of the DSN specified in the connection string. Listing 1 offers a sample db2cli.ini file.

; DSN section here 'DSNSAMPLE' is the DSN name
[DSNSAMPLE]
Database=SAMPLE
Hostname=server1.net1.com
Port=45672

;COMMON section
[COMMON]
AutoCommit=1

A closer look at the db2dsdriver.cfg configuration file

The db2dsdriver.cfg configuration file is an XML file that is based on the db2dsdriver.xsd schema definition file. Listing 2 offers a sample db2dsdriver.cfg file.

<configuration>
	<dsncollection>
		<dsn alias="alias1" name="name1" host="server1.net1.com" port="50001"/>
	</dsncollection>
	<databases>
		<database name="name1" host="server1.net1.com" port="50001">
		<parameter name="Authentication" value="Server_Encrypt"/>
	</database>
	</databases>
	<parameters>
		<parameter name="GlobalParam" value="Value"/>
	</parameters>
</configuration>

The sample configuration file contains the following sections:

• A data source name section, which is contained within the <dsncollection> tags
• A database information section, which is contained within the <databases> tags
• A global attributes section, which is contained within the <parameters> tags

If the keyword is initialized with a specific value in the connection string and the same keyword is set with a different value in the db2cli.ini or db2dsdriver.cfg file, the value in the connection string takes precedence. The keyword with a different value in the db2cli.ini or db2dsdriver.cfg is ignored.

Utilities

Several user-friendly utilities are shipped with the IBM Data Server Driver Package. Following are these utilities, which are located in the bin folder of the install directory.

db2cli tool

This utility is an interactive tool that can be used to perform the following operations:

db2dsdriver.cfg schema validation

The db2dsdriver.cfg configuration file that the application uses might not be complaint with the existing schema. In such cases, the CLI driver will not read the parameters specified in the db2dsdriver.cfg, which makes it difficult to identify any schema problem in db2dsdriver.cfg. You can easily solve this problem by using the db2cli tool with the validate option specified: db2cli validate. This performs the db2dsdriver.cfg schema validation and, upon finding any schema errors, displays them with specific tag names and line numbers.

Keywords and parameters validation

Applications can specify certain keywords and parameters in the db2cli.ini configuration file under a particular DSN section. During connection, the CLI driver reads those keywords and parameters, and if any keywords or parameters are spelled incorrectly, the driver ignores those misspelled keywords and parameters. You can use the db2cli tool with options to check the validity of the keywords and parameters: db2cli validate -dsn <dsn name> . The db2cli tool provides the list of valid keywords and parameters that the driver reads during connection.

On the other hand, if you provide connection parameters in the database section of the db2dsdriver.cfg file, the validation of those parameters can also be done with the db2cli utility: db2cli validate -database <dbname:server:port> . In this case the matching DSN section need not be present in the db2dsdriver.cfg file.

Note that the db2cli validate command also displays the path from where the configuration files are read: db2cli validate -help

Addition and removal of DSN information

The db2cli utility provides a Windows platform-specific option that enables you to add or remove a DSN in the Microsoft ODBC Data Source Administrator, as shown in Listing 3
Listing 3. Add or remove a DSN

db2cli registerdsn –add <dsnname> db2cli registerdsn –remove <dsnname>

When the db2cli utility is invoked with this option, the utility reads the DSN specified in either the db2cli.ini or db2dsdriver.cfg file and adds it under the System or User DSN section of the Microsoft ODBC Data Source Administrator section. For more information, invoke the help text by typing: db2cli registerdsn –help .

Execution of interactive CLI scripts

The db2cli utility can be used to quickly prototype and analyze the driver behavior by executing sample test cases. For more information, invoke the help text by typing: db2cli –help

See Resources for db2cli online help.

db2dsdcfgfill utility

When a copy of IBM Data Server Client or IBM Data Server Runtime Client is installed on a server, entries for all catalogued databases are located in the database directory. By invoking the db2dsdcfgfill utility after the IBM Data Server Driver Package has been installed, you can create and populate the db2dsdriver.cfg file automatically using the database entries found in the database directory: db2dsdcfgfill –I <instance-name>

For more information, invoke the help text by typing: db2dsdcfgfill -?.

testconn11 and testconn20

Applications using .NET can quickly check the database connectivity with the testconn utility. testconn11 and testconn20 utilities correspond to .NET Framework Versions 1.1 and 2.0, respectively. For example, database connectivity with .NET Framework 2.0 can be tested by typing the following:
Testconn20 Database=db2db;Server=mymachine:60000;UserID=db2user;Password=xxxxxxxx

db2trc

Use this utility generate a trace if errors are encountered when an application attempts to use the IBM Data Server Driver Package to perform database-related operations. Complete the following steps to perform a trace:

1. Enter db2trc on -cli -f <trcfilename.dmp>.
2. Run the application by entering db2trc off.
3. Generate a CLI trace file with .dmp trace file by entering db2trc fmt -cli <trcfilename.dmp> <trcfilename.cli>

CLPPlus

CLPPlus is a unified command line processing tool that is capable of executing SQL commands and SQL scripts. Following are additional functions available in the CLPPlus tool:

• Support for generating formatted reports for the executed queries
• Support for developing SQL scripts and execution of selected utility commands supported by the IBM Data Server Driver.
• Capability to easily migrate existing scripts from non-IBM data servers to the IBM Data Server Driver Package.

See Resources for more information about the CLPPlus utility.

Diagnostic support

Applications using IBM Data Server Driver Package can diagnose database-related problems by performing a trace. The ODBC, CLI driver, open source drivers, and OLE DB drivers can all use the CLI tracing mechanism. A CLI trace can be enabled with the db2trc utility. A CLI trace can also be enabled by adding keywords, such as Trace and TracePathName, to the db2cli.ini file. For example, these keywords can be specified in the COMMON section of the db2cli.ini file, as shown in Listing 4.

[COMMON]
Trace=1
TracePathName=<path>

For more information about tracing mechanisms, see Resources.

A JDBC or SQLJ trace can be enabled using configuration properties. See Resources for more information about JDBC and SQLJ tracing mechanisms.

Installing the IBM Data Server Driver Package in Windows environments

After you have edited the configuration files appropriately, you are ready to install the IBM Data Server Driver Package. The IBM Data Server Driver Package on Windows can be installed in any of the following ways:

• From a fixpack image
• From the product DVD
• Using the command line

Prerequisites

• The IBM Data Server Driver Package must be installed separately.
• No other DB2 database product can be installed in the same path if the IBM Data Server Driver Package is already installed.
• Only one copy of any data server client package is recommended. You should uninstall any existing data server client package installations if migrating from another client package.
• The DB2 setup wizard does not accept non-English characters.

Installing the IBM Data Server Driver Package from a fix pack image (Windows)

Complete the following steps to download and install the IBM Data Server Driver Package from a fix pack image on the Windows platform.

1. Download the driver package that contains the setup program from the IBM Support Fix Central Web site (see Resources).
2. Run the setup executable to begin installing the downloaded IBM Data Server Driver Package. Figure 2 shows the resulting welcome screen.
   
   Figure 2. Welcome screen

   Figure 6. Reviewing the installation settings
   
   
   

After installing the IBM Data Server Driver Package, you can optionally create and populate the configuration file, db2dsdriver.cfg, with database directory information. See Resources for help populating the db2dsdriver.cfg file.

Installing the IBM Data Server Driver Package using the command line options

The setup command can be issued with many options to perform a wide range of operations, as shown in Table 4.

For example, to install a new copy with a generated default COPY_NAME, use the command setup /o. To install a second copy (though this is not recommended), use the command setup /n <COPY_NAME> .

Installing the IBM Data Server Driver Package from the product DVD (Windows)

1. Log on to the system with the user account that you want to use to perform the installation.
2. Optionally shut down any other programs.
3. Insert the DVD into the drive. The auto-run feature starts the DB2 setup wizard, which determines the system language and starts the setup program for that language.
4. Run the setup command from the product DVD. There are separate installation images for each language. Run setup.exe with the -i parameter to specify the two-letter language code for the language the installation is to use.

Upgrading the IBM Data Server Driver Package (Windows platform only)

If the IBM Data Server Driver Package has been installed on a Windows server, it can be upgraded in one of the following ways:

• At the release level
• At the inter-fix-pack level

Upgrading at the release level (Windows)

Upgrading the IBM Data Server Driver Package from the current release to a new release is equivalent to a new installation. The installation wizard installs the latest version of the IBM Data Server Driver Package at a different location with a new copyname. Complete the following steps to install the upgrade.

1. Download the latest release of the IBM Data Server Driver Package setup.exe file.
2. Run the setup.exe to start the installation at the new path. The IBM Data Server Driver Package product is installed at the new location. A new COPY_NAME is created at location C:\Documents and Settings\All Users\Application Data\IBM\DB2\<COPY_NAME>.
3. Uninstall the previous release of the IBM Data Server Driver Package if it is no longer required.

Upgrading at the inter-fix-pack level (Windows)

On the Windows platform, for an inter-fix-pack-level upgrade, you can install at the same path where the previous fix pack was deployed. In this case, the new installation files override the previous installation files, but the old COPY_NAME is retained. Complete the following steps to install the upgrade.

1. Download the inter-fix-pack-level IBM Data Server Driver Package setup.exe file.
2. Run the setup.exe to start the installation. The installer identifies whether a fix pack of the same release is already installed, as shown in Figure 7.
   
   Figure 7. Warning message
   
   
   
3. Click Yes if you want to install in the same location as the COPY_NAME. This is recommended.
4. Click No and run the setup.exe from the command prompt. Enter setup.exe /n <COPY_NAME> if you want to install in a different path and a new COPY_NAME, which is not recommended. If installing with the current COPY_NAME, the existing configuration files db2cli.ini and db2dsdriver.cfg are retained at the same location. The new binaries are replaced at the existing installed location. The advantage of this is that the applications can run with the new driver version without modifying anything.

killenv 1

The interactive CLI script in Listing 5 can be executed by giving the test case file as input to the db2cli tool, as shown in Listing 6.

 
 INSTALL-DIR\bin\db2cli < test.txt

Using the Ruby tool

Listing 7 shows the database connection example using the Ruby driver.

 
require 'ibm_db'    #If on windows, require 'mswin32/ibm_db'
dbalias = 'userid'
begin
#Connect to railsdb via the DSN alias userid in configuration file
conn = IBM_DB.connect(dbalias,'','')
puts "Connection to alias #{dbalias} is successful"
#Close the open connection
IBM_DB.close conn
rescue StandardError => conn_fail_error
raise "Failed to connect to: #{dbalias}. Reason: #{conn_fail_error}"
end
