The Db2 11.5 documentation has all the information users will need to get started with Db2, including topics for Administrators. However, it can be a bit daunting and overwhelming to have to dive into all that content in one go. 

The Db2 product hub is a curated experience to get you started. Using all types of content including the Knowledge Center, the Db2 product hub is a great place to start for users looking for a more guided approach, including Db2 Administrators. 

The Db2 product hub has a specific Db2 Administrators section which has hand-picked material tailored for Db2 Administrators from setting up administration security to server management. And when users are ready, there's also a section on advanced database administration. 

Find the information you need in our Db2 product hub.
