Offers optimizer plan and ALSM features along with exceptional stability

The TSA version of IBM Db2 Database doesn't meet my stability expectations. Every time when a switch over occurs, some stability issues can be noticed. The vendor should offer a free version of IBM Db2 Database. For instance, if our company wants to train new individuals on all the features of IBM Db2 Database, they can only be trained after purchasing the paid version of the solution. About ten years ago, a trial version was available for the solution that was highly beneficial for companies. The vendor can add AI or ML features in the future version of IBM Db2 Database.
