On the Basic page, use the Status subsection to find out whether your authorization ID has access to a set of EXPLAIN tables to use for gathering EXPLAIN information about the SQL statements that you tune. Use the Features subsection to see a list of the features that are enabled for use.
On the Advanced page, find out whether the stored procedures for scheduling tasks to run on the connected DB2® for z/OS® subsystem are configured correctly. If you want to schedule tasks to run on query workloads by using the DB2 for z/OS administrative scheduler, two stored procedures must be enabled: SYSPROC.OPT_EXECUTE_TASK and SYSPROC.OPT_RUNSQL. See Configuring a DB2 for z/OS subsystem for the Optim™ Query Tuner client from the server side.
