DB2 Configuration Manager for z/OS V5.1 (inside DB2 Admin Soln Pack
only )
DB2 Query Workload Tuner for z/OS V5.1 (standalone, DB2 Perf Soln
Pack)
Features of the Data Server Manager Based Tools At A
Glance
Data Server Manager Base
• Connect to DB2 for z/OS V10 and V11. • Database object navigation, viewing
object detail, and linking to related objects.
• Database object dependency display. • Data browsing and editing. • Basic database object operations, such
as creation of tables, indexes, constraints, and tablespaces; dropping of tables, indexes and constraints; altering tables.
• Showing system privilege from the perspective of Group/User, Role, or SQL object. Choose:-"Group/User" to see the role and the relative object privilege for a user account; - "Role" to see the role a user account belongs to and its relative object privilege;- "SQL object" to see a specific object and users or roles that have the relative authority.
• Single Query Tuning • Statistics Advisor• Query Environment Capture • Access Path Graph
• Launching of visual explain and tune query on the SQL editor
• A new tuning wizard to capture SQL statements from multiple sources
• Several Tuning advisors provide recommendations for:
• Statistics Advisor• Index Advisor• IDAA Advisor
• Understand problem query or workload • Access plan graph• Query formatting and annotation• Tuning Report• Test Candidate Index• Access Plan Comparison• Index Impact Analysis• Query and Workload
Environment Capture
• Track Configuration Changes• Configure zParm• Compare and Clone Configurations• Manage Application Profile• Manage alias• Manage clients
DB2 Utility Solution Pack V2.2
• Customizable profiles for identifying object situations and generating resolving JCL (reorg, copy, runstats, etc)
• Automatic prioritization of object situations and their resolving actions
• Ability to define maintenance windows for enabling active autonomics, allowing DB2 to self manage utility runs
• Notification support (email, text, WTO) on selected autonomic events
• Graphical trend analysis of historical RTS• Capture of utility history, recording utility
output, time, duration, etc.

What’s New for DSM V2.1 for DB2 for z/OS
• Query Tuning Enhancements
– As a DBA I have opened up a pmr with support and want to send in diagnostics –use collector tool to send diagnostics to IBM support team
– DBA could not connect to the internet so give ability to download diagnostic files locally
– A DBA or Application Developer wants to get a single query target tuning job from a Workload Statements View
– As a DBA want to use the CAPTURE statement to check the statement’s catalog package for information such as COLLID, NAME, VERSION, statement runtime information to refine workload, View Runtime Access Plan Graph, View Bind Time Access Plan Graph
– No charge Single Query Tuning now available

Identify query candidates from
numerous sources
– DB2 catalog
– Dynamic statement cache
– User defined repository
Facilitate analysis
– Query formatting
– Query annotation
– Access path visualization and
annotation
Get expert tuning advice
– Improve statistics quality
– Improve database design
– Improve accelerated queries

• Statistics
– Get recommendations on the best statistics to capture to influence access path selection
• Index
– Get recommendations on indexes changes that can reduce database scans
• Analytics Accelerator

Improve Statistics Quality and Collection
• Results
• Accurate estimated costs
• Better query performance
• Less CPU consumption
• Improved maintenance window throughput

Analytics
Analyze Access Plans
New Recommendation Integration
Visualize access path – See flow of query
processing– See indexes and
operations– See optimizer
rationale
Assess access path stability to reduce risk of performance regression– Is the optimizer able to
apply the filtering early?
– Are there indexes that support an efficient path?
– Do statistics allow distinction between the choices?

Indexing Advice to Improve Query Efficiency
• Improve query efficiency
• Indexing foreign keys in queries that do not have indexes defined
• Identifying index filtering and screening
• Support for index only access
• Indexing to avoid sorts
• Simplify use
• Consolidate indexes and provide a single recommendation
• Enables what-if analysis
• Provides DDL to create indexes
• Run immediately or save
• Test before deployment
• Utilize virtual index capabilities built into the DB2 engine

Optimizing the Selection, Tuning and Access Plan Analysis
of Accelerated Workloads
Workload Analytics Accelerator
Advisor • Identify candidate queries and tables to be routed to the
accelerator
• Identify candidate tables to be routed to the accelerator
• Implement advisor-based tuning recommendations for
mixed
workloads of accelerated and un-accelerated queries
• Diagram accelerated queries in Access Plan Graphs
• Integrates with Query Monitor and OMPE for capturing
query workloads for complete analysis
• Enable “what if” analysis
Benefits• Shorten the process of selecting tables to be
accelerated
• Visualize access paths of accelerated queries
• Increase productivity by working with accelerated
queries through a unified interface
Increase overall system capacity

Prevent Problems Before They Impact the Business
• Optimize beyond the prior level of
service.
• Determine whether the later
version of the collection has
degraded performance.
• Determine whether any packages
have errors.
• Identify which packages have SQL
statements that have degraded
performance
• Available Actions
• Apply filters and review
Comparison result
• Review comparison result
• Generate HTML comparison
report
• Generate new query workload for
tuning & perform analysis
• Enhancements
• Compare two different workloads
• Utilize runtime metrics
• Access plan lockdown for SQL
