Db2 12 for z/OS: Improving Availability and Resilience.
IBM Db2 for z/OS clients need the highest possibility availability to be able to meet their own business requirements and to satisfy the expectations of their customers. This Webcast explores the improvements introduced in Db2 12 for z/OS, to strengthen its position as the premier high-availability relational database. There are two areas of focus, the first being further enhancements to on-line schema migration, making it easier to change database design and attributes non-disruptively. The three topics here are: online ALTER to increase the maximum page-set size (DSSIZE); increasing the partition size limit to 1 TB and massively increasing maximum table size; and the ability to insert a partition anywhere in the partitioning scheme. The second area of focus is removing a potential single point of failure, by the introduction of asynchronous Coupling Facility lock duplexing.
