This article covers how to obtain DB2 UDB client libraries to work with Javelin (along with TDM and its related components).
In the documentation, we see the following reference to DB2:
Automating Database Activities (broadcom.com)
DB2 functions let you automate various database operations in Javelin flows.
Execute Query: Executes a query against an IBM DB2 database.
The query can be either Select, Insert, Update, or Delete.
For Select queries, output rows are assigned to an output variable which is set in the OutDataTable property.
Note: You must have IBM DB2.NET Data Provider version 126.96.36.199 installed for this activity to work.
Where can we get these libraries from IBM?
Test Data Manager
The IBM Data Server client should provide the required libraries.
Depending on the DB2 version, you can download the latest pack.
The link given below, provides the full details of all the downloads arranged by DB2 version.
IBM Download Fix Packs by version for IBM Data Server Client Packages - United States
You will need to have an IBM account to download it.
If you are not able to access it, you might have to reach out to your DBA to get the correct libraries, since these libraries are not openly distributable.
