DB2 12: Hear What the customers are saying…

DB2 12 – More Control over Dynamic Plan

Stability

“Dynamic Plan stability give us much better options to control and

manage dynamic SQL. It is very important for us, as dynamic

SQL becomes more and more popular. Dynamic SQL becomes

an increasing part of our workload and we want to have the same

control of Dynamic SQL as we have had for Static SQL for years.”

Henrik Henriksen

Danske Bank

Mainframe & Midrange Services

Gaining Deeper Insight with DB2 12

““I am excited about all of the great new SQL functionality that is

coming with DB2 12. Things like FETCH FIRST on DELETE,

simpler pagination, and of course, tons of performance

enhancements, will make it easier than ever to get insight from our

DB2 databases.”

Craig Mullins

IBM GOLD Consultant

IBM Champion for Analytics

DB2 12 - The #1 Enterprise Server offering “in-memory”

technology

“In the past few releases of DB2 for z/OS, IBM has systematically removed the most

significant virtual storage limits DB2, so that customers can more fully exploit the real

storage available in their System z servers. The “in-memory” features of DB2 12 take this

a step further, allowing customers to really take advantage of today’s larger memory

configurations in order to significantly reduce operational costs and improve

application performance. There’s more still to do, but DB2 is now a bona fide in-memory

database.”

Julian Stuhler

DB2 Specialist, IBM Gold Consultant,

IBM Champion for Analytics

DB2 12 – RESTful API helping enterprises

to be Agile

“Restful API in DB2 12 for z/OS allows you to develop mobile and

other apps with scalable performance in a matter of minutes. Do you

want to be quick and agile ? Use Restful API in DB2 12 for z/OS”

What is it? • An in-memory database (IMDB) is one that primarily relies on main memory

for data storage (as opposed to disk)

What does this mean? • New and existing workloads can benefit tremendously

• Ex. Fast lookup of transactional data from mobile devices

• The DB2 Lab has measured up to a 23% reduction in CPU

on existing workloads

• Memory on the z platform is getting larger and cheaper

• We expect more growth in future hardware

• DB2 12 exploits large memory for improved performance and

CPU reductions

• Larger buffer pools to reduce I/O – up to 4 TB

• New memory optimized structures to speed up performance

• Fast Traverse Blocks (FTBs), Contiguous Buffer Pools,

fast insert pipes, …

DB2 12 is an In-Memory Database

DB2 In-Memory database means faster transactions and queries, with lower CPU overhead

Not to be confused with IDAA value

IDAA

• Accelerates complex analytical queries, up to

2000x faster than traditional DB2 could

• Is a hybrid data store that allows DB2 to deliver

industry leading performance for mixed

workloads

In-memory DB2

• Can be used to speed up and lower the overhead of

DB2’s traditional workloads (primarily OLTP-based)

• Can very much be used in conjunction with IDAA

© 2017 IBM Corporation 21

In-Memory Index Optimization

A new Index Fast Traverse Block (FTB) is introduced Memory optimized structure for fast index lookups

Resides in memory areas outside of the buffer pool • New zparm INDEX_MEMORY_CONTROL

• Default=AUTO (min. of 500 MB or 20% of allocated BP storage)

UNIQUE indexes only, key size 64 bytes or less

DB2 automatically determines which indexes would benefit from FTB

DISPLAY STATS command shows which indexes are using FTBs

New SYSINDEXCONTROL catalog table

Specify time windows to control use of FTBs for an index

New IFCIDs 389 and 477 to track FTB usage

Dynamic SQL Plan Stability

• Problem:

– Unstable performance of repeating dynamic SQL statements

– Environmental changes can result in change in access path or performance regression, and this can be tough to manage

• RUNSTATS

• applying sw maintenance

• DB2 release migration

• zparm changes

• schema changes

• Static SQL has several advantages – Access path established at BIND time

– Static plan management gives advanced management functions

• Objective: extend static SQL advantages to dynamic SQL

DB2 12 DRDA Fast Load

• Problem:

• DB2 provides the DSNUTILU stored procedure to load data from a client

• But this is difficult to use, app must xfer data to z/OS file

• Solution:

• DB2 Client API (CLI and CLP) for remote load into DB2

• Easy/fast loading of data from file that resides on client

• Internal format (SAP), as well as delimited and spanned (LOB data)

• Overlap network operations with data ingest on the DB2 server

• Measured results show as fast or faster than DB2 LOAD utility

• zIIP eligible

• DB2 z/OS initial support for MERGE statement with limited functionality was

delivered with Version 9:

• Limited to UPDATE and INSERT and only one of each

• Focused on use of host variable column arrays to provide multiple rows of input

data

• In DB2 12, DB2 z/OS MERGE statement will be aligned with behavior defined in

SQL Standard and DB2 family.

• Source data as a table-reference

• Multiple MATCHED clauses

• Additional Predicates with [NOT]MATCHED

• Support DELETE operation

• Allow IGNORE and SIGNAL

© 2017 IBM Corporation 34

SQL Pagination

With the growth of web and mobile applications, application developers are

looking for more efficient ways to develop good performing applications.

Numeric-based pagination SELECT * FROM tab OFFSET 10 ROWS FETCH FIRST 10 ROWS ONLY

Data-dependent pagination Existing syntax

WHERE (LASTNAME = ‘SMITH’ AND FIRSTNAME >= ‘JOHN’) OR

(LASTNAME > ‘SMITH’)

New equivalent syntax

WHERE (LASTNAME, FIRSTNAME) > (SMITH, JOHN)

© 2017 IBM Corporation 35

Piece-wise Modification of Data

Mitigate the effects of locking and logging when potentially millions of rows

could be affected by a simple statement like:

"DELETE FROM T1 WHERE C1 > 7“

Solution

Allow the fetch clause to be specified on a searched delete statement

DELETE FROM T1 WHERE C1 > 7 FETCH FIRST 5000 ROWS

ONLY;

COMMIT;

© 2017 IBM Corporation 36

• Relief for table scalability limits

• Simplify large table management

• Improve availability

• Agile schemas (more online schema changes)

• Security and compliance improvements

• Streamline migration process

• Utility performance, availability, usability

DBA Productivity – DB2 12 Goals

© 2017 IBM Corporation 37

Partition By Range Current Limitations

Maximum table size limited to 16Tb (4k pages) or 128Tb (32k pages)

Maximum number of partitions is also dependent on DSSIZE and page size

E.g. if DSSIZE = 256 GB and page size = 4K then Max Parts is 64

DSSIZE is at Table Space Level not Part Level

All Parts inherit the same DSSIZE set at Table Space

No ability to have differing Partition sizes

Altering DSSIZE requires REORG of entire tablespace

© 2017 IBM Corporation 38

DB2 12 Lifting the Limits

New PBR tablespace structure called ‘PBR RPN’

Relative page numbers (RPN) instead of absolute

Remove dependency between #partitions & partition size

New RID is Relative RID

Part Number stored in Partition Header Page

Page number stored in Data Page, relative to start of the partition

Up to 1TB Partition Size, or 4 Petabytes (PB) per table space

Maximum number of rows with 4K pages increased from 1.1 to 280 Trillion

@1,000 rows inserted per second, more than 8800 years to fill!

Increasing DSSIZE is supported at partition-level

New DSSIZE support for indexes

These infrastructure changes position DB2 for future enhancements

Increase in partition limits, increase number of rows per page

Attribute variance by partition, schema changes via REORG PART

Improved efficiency

Further reduction in CPU cost & more offload to zIIP

• REORG up to 57% zIIP offload

• LOAD up to 90%

REGISTER NO option to eliminate data sharing overhead for RUNSTATS, UNLOAD

COLGROUP statistics CPU cost reduced by up to 25%, elapsed time up to 15%

More efficient handling of compressed data to reduce CPU and elapsed time across range of utilities

REORG avoidance: Immediate increase of partition DSSIZE with PBR RPN

Improved FlashCopy support

• Multiple DFSMS COPYPOOL support for SLBs & better messaging

• Improved FlashCopy handing in REORG & template support for MGMTCLAS, STORCLAS

Eliminating application impact

Improved LOAD utility support for sequences with automatic handling of MAXASSIGNEDVAL

Online LOAD REPLACE – non-disruptive refresh of reference tables

Skip invalidation of cached statements by RUNSTATS

Removed recoverability restrictions for PBG table spaces

© 2017 IBM Corporation 42

Data Sharing Improvements

Support for global transactions

DDF shared session data across group

DDF transaction re-routing, session token for client fail-over

Data sharing performance improvements:

Improved lock avoidance checking to reduce CF lock requests

In-memory indexes can reduce GetPages and CF GBP requests

Improved insert space search can avoid P-lock contention and streamline inserts

RUNSTATS and UNLOAD ISOLATION(UR) to avoid CF page registration

© 2017 IBM Corporation 43

Data Sharing Improvements …

New data sharing peer recovery option

Retry of automatic LPL and GRECP recovery

Asynchronous CF Lock duplexing

Reduces overhead for system managed duplexing of CF LOCK1 and SCA structures

Secondary structure updates are performed asynchronously with respect to primary updates

DB2 will sync up with z/OS to ensure data integrity i.e., all modify locks have been “hardened” in the

secondary lock structure before the corresponding undo/redo record for the update is written to DB2 the

active log on DASD

Increases the practical distance for multi-site sysplex operations while duplexing of CF LOCK1 structure

Requirements:

• z/OS 2.2 SPE with PTFs for APARs OA47796 and OA49148

• CFCC Level 21 (z13)

• DB2 12
