Do we need JDK installed to use JDBC snap?

I have on-prem groundplex. We need to connect mainframe Db2 database. I heard we can do that by using JDBC select snap. In order to use JDBC snaps, do we need JDK installed in our machine?

No, for SnapLogic you do not need to have the JDK installed to use the JDBC Snap. You will need to configure the JDBC Account to use the necessary DB2 JDBC driver, and include any dependencies.

If not prerequisite software installation required means, what I need to provide under JDBC Driver Class while configuring JDBC account to access mainframe DB2?

JDBC Driver Class name -
