Highlights of DB2 Version 10.5IBM DB2 Version 10.5 for Linux, UNIX, and Windows offers accelerated analytic processing by introducing a new processing paradigm and data format within the DB2 database product. Advantages include significant reductions in time-to-value and increased consumability, which can be achieved through minimal DBA design requirements and reduced query tuning and debugging efforts. Industry-leading compression, large performance gains for analytic queries, and large reductions in performance variation round out the benefits of deploying this technology.
DB2 Version 10.5 fix packs deliver additional enhancements and product changes.

Support for high availability disaster recovery (HADR) Increased availability Improved workload balancing Restore mobility between DB2 pureScale Feature and DB2 Enterprise Server Edition
Performance improvements:
Continuing to build on prior release performance improvements, V10.5 performance improvements focus on explain information for column-organized tables and extension to the CREATE INDEX statement to create an index containing an expression-based key.
SQL compatibility:
If you work with relational database products other than DB2 products,V10.5 builds on existing functionality, interfaces, and compatibility features to provide additional enhancements that make DB2 products more familiar to you. These enhancements reduce the time and complexity of enabling applications that are written for other relational database products to run quickly in a DB2 environment.
