Abstract
Download Db2 v12.1.4 Published CSB (Cumulative Special Build) for Db2® for Linux®, UNIX®, and Windows® and Db2® Connect™ products.
Use this page to download a Db2 CSB for the installed Db2 product you have. Db2 CSB images are delivered from Fix Central. Special builds are cumulative. Included are links for Db2 Universal, Db2 Server, Db2 Connect, Net Search Extender, Spatial Extender, Query Patroller, Db2 Client, Db2 Run-Time Client, Db2 Wrappers, and all drivers (ODBC, CLI, JDBC, .NET). Click on the CSB to view it.
CSB are cumulative, each CSB contains all fixes delivered in previous CSB.
CSB are listed most recent from top to bottom -- thus the earlier listed CSBs contain all the fixes listed further down.
CSBs cannot be time ordered solely based on number.
Note:
CSB and the KI (Known Issues) listed might change retroactively.
Not every CSB is provided in this list.
Security KI will be added only after they are officially announced.
