IBM data server driver clients and drivers enhancements

Some IBM data server clients and drivers have been enhanced to improve application performance and reliability.

Attention: The enhancements in this topic are included in the Db2 11.5.4 mod pack release, which is available for the following products:

Db2 on-premises
The single container deployments of Db2 Warehouse and IBM Integrated Analytics System (IIAS)
The container micro-service deployment of Db2 on Red Hat OpenShift

To successfully use version 11.5 Mod Pack 4 features, you must upgrade to a version 11.5 IBM® data server client or driver.

In general, you can use Db2 version 11.5, version 11.1, and version 10.5 clients and drivers for running applications, developing applications, and performing database administration tasks on Db2 version 11.5. Likewise, you can use version 11.5 clients and drivers for running applications, developing applications, and performing administrative tasks on Db2, version 11.1 and version 10.5 servers. However, the functionality available can differ based on the combination of the version levels that are used on the server and client (or driver).
