The application does have db2 client dependence, If you don’t have db2 client install, you will get the error “File not found db2cli”

To fix this error, we need to install db2 client.

DB2 Client

There are various db2 client available .

  • IBM Data Server Driver Package
  • IBM Data Server Driver for JDBC and SQLJ
  • IBM Data Server Driver for ODBC and CLI
  • IBM Data Server Runtime Client
  • IBM Data Server Client

Because I only need the db2cli capability, I decide to choice the smaller footprint “IBM Data Server Driver Package” .  The package can be download from this link. The db2demo is 32-bit application,therefore the 32-bit db2 client is required.

Configure the db2 server client

Compare to RUNTIME client, There are 2 major short for the IBM Data Server Driver Package :

  1. NO DB2 cmd
  2. Can not catalog the database.

In order for db2 to know where is the database, we have to update the db2dsdriver.cfg.

The path of the db2dsdriver.cfg is in the C:\ProgramData\IBM\DB2\IBMDBCL1\cfg , Here is my sample of the configuration file.

<configuration>
   <dsncollection>
      <dsn alias="db2inst97" name="SAMPLE" host="192.168.208.129" port="50001"/>
      <!-- Long aliases are supported -->
   </dsncollection>
   <databases>
      <database name="SAMPLE" host="192.168.208.129" port="50001">
      </database>   
   </databases>
</configuration>

Start DB2demo

The db2demo works properly after the db2dsdriver.cfg is set.
