Best Practices For Optimizing DB2 Performance FinalDatavail
DB2 performance tuning and optimization is a complex issue comprising multiple sub-disciplines and levels of expertise. Mastering all of the nuances can take an entire career. Deploying standard best practices can minimize the effort to achieve efficient DB2 applications and databases.
This white paper outlines the most important aspects and ingredients of successful DB2 for z/ OS performance management. It offers multiple guidelines and tips for improving performance within the three major performance tuning categories required of every DB2 implementation: the application, the database and the system.
The document discusses IBM's Db2 database family and the latest 11.1.4.4 update. It notes that IBM's statements regarding future products are subject to change and should not be relied upon, and that performance will vary by user. The document then summarizes key capabilities and enhancements of the Db2 Common SQL Engine, including investment protection, support for different workloads, consistent technical capabilities, and flexibility of deployment. It also provides an overview of the Db2 11.1 lifecycle and modification levels, and describes how customers can get critical fixes between official updates.
The document discusses DB2's use of storage on the mainframe. It notes that DB2 uses VSAM data sets to store tablespaces, indexes, and other objects. These data sets can be managed by DB2 storage groups or SMS. Storage groups are lists of volumes where data sets are placed. The document recommends letting DB2 manage data sets using storage groups for less administrative work, but with less control, or defining your own data sets for more control but more work. It also provides details on where to find storage-related information in the DB2 catalog.

Best practices for DB2 for z/OS log based recoveryFlorence Dubois
The need to perform a DB2 log-based recovery of multiple objects is a very rare event, but statistically, it is more frequent than a true disaster recovery event (flood, fire, etc). Taking regular backups is necessary but far from sufficient for anything beyond minor application recovery. If not prepared, practiced and optimised, it can lead to extended application service downtimes – possibly many hours to several days. This presentation will provide many hints and tips on how to plan, design intelligently, stress test and optimise DB2 log-based recovery.
The document provides an overview of performance management tools in Oracle 12c, including the Cost Based Optimizer, SQL profiles, Oracle SQL Plan Management (SPM), and Oracle Real Time Monitoring.

The Building Blocks of QuestDB, a Time Series Databasejavier ramirez
Talk Delivered at Valencia Codes Meetup 2024-06.
Traditionally, databases have treated timestamps just as another data type. However, when performing real-time analytics, timestamps should be first class citizens and we need rich time semantics to get the most out of our data. We also need to deal with ever growing datasets while keeping performant, which is as fun as it sounds.
It is no wonder time-series databases are now more popular than ever before. Join me in this session to learn about the internal architecture and building blocks of QuestDB, an open source time-series database designed for speed. We will also review a history of some of the changes we have gone over the past two years to deal with late and unordered data, non-blocking writes, read-replicas, or faster batch ingestion.

13. Performance Improvement for high concurrent workload
• Run a number of performance tests before upgrading your DB2 server.
• The db2batch benchmark tool helps you to collect elapsed and CPU times for running
queries. You can use this tool to develop performance tests.
• Also, keep a record of the db2exfmt command output for each test query. Compare the results
before and after upgrade. This practice can help to identify and correct any performance degradation
that might occur.
• For our test environments we used below db2batch command to collect before and after
performance test results,
• db2batch —d DBNAME —f PerfTestLoad.sql —r AfterUpOut.fil —i complete —o e yes —isol CS
• Before Environment – DB2 v 9.7 FP5
• After Environment – DB2 v 11.1
• Overall timing improvement, we got is around is 48% just by upgrading to DB2 v 11.1
• Workload we tested is typical OLTP Payment processing highly concurrent queries.
14. Database Manager CFG Parameter Changes
• MON_HEAP_SZ
• Range of MON_HEAP_SZ extended on 64-bit instances from 0-2,147,483,647.
• INSTANCE_ MEMORY
• Can now specify INSTANCE_MEMORY limit by calculating percentage of available
RAM divided by number of local partitions, or specify memory limit as number of 4KB pages.
• AUTOMATIC (Default) Computed value ranges between 75 percent and 95 percent of system
memory.
• 1 - 100: Specifies instance memory limit by calculating percentage of available RAM divided by
number of local partitions. In-memory value is updated at member startup time to reflect calculated
number of 4KB pages. Used to set DB2's percentage consumption of total RAM on machine in DB2
instances with heterogeneous machine hardware configurations.
• 101 - system memory capacity. Specifies memory limit as number of 4KB pages. Also represents
tuning target if STMM is enabled.
15. Database CFG Parameter Changes
• APPLHEAPSZ
• Range of APPLHEAPSZ extended on 64-bit instances from 16 - 2,147,483,647. It also changed from
Uint16 type to Uint64 type.
• CATALOGCACHE_SZ
• Range of CATALOGCACHE_SZ extended on 64-bit instances from 8 - 2,147,483,647.
• DBHEAP
• Range of DBHEAP extended on both 32-bit and 64-bit instances from 32 - 2,147,483,647.
• STAT_HEAP_SZ
• Range of STAT_HEAP_SZ extended on 64-bit instances from 1 ,096 - 2,147,483,647.
• STMTHEAP
• Range of STMTHEAP extended on 64 bit instances from 128 - 2,147,483,647.
16. Administration Improvements
• DB2 11.1 includes a number of administrative enhancements that
DBAs will find useful. Four of them that are highlighted here include:
• Range Partition Table Reorganization
• A single partition of a range partitioned table can now be reorganized with the
INPLACE option if:
• Table has no global index (i.e. non-partitioned indexes)
• ON DATA PARTITION is specified
• The reorganization can only occur on one data partition at a time, and the table must
be at least three pages in size.
• ADMIN_MOVE_TABLE improvements
• Two new options in the ADMIN_MOVE_TABLE command:
• REPORT
• TERM
17. Administration Improvements
• DB2 History File Backup
• The DB2 history file contains information about log file archive location, log file chain, etc.
• If you use snapshot backups you want to have current information about log file location to
perform point in time recovery (RECOVER command). RECOVER needs a current version of the
history file to be available.
• db2 "BACKUP DB <alias> NO TABLESPACE to /histbkup"
• db2 "RESTORE DB <alias> FROM /histbkup HISTORY FILE"
• Remote Storage
• DB2 11.1 delivers more flexibility and options for acquiring, sharing and storing data files and
backup images, by allows customers to use remote storage for several DB2 utilities:
• INGEST, LOAD, BACKUP, and RESTORE
• DB2 supports remote storage using storage aliases for:
• IBM® SoftLayer® Object Storage
• Amazon Simple Storage Service (S3)
• LOAD FROM <remotefilename>
18. CREATE TABLE Extensions
• CREATE TABLE can now use SELECT clause to generate table definition and populate
table with data
• CREATE TABLE TABTEMP AS (SELECT FROM TABLE1) WITH DATA ;
• CREATE TABLE AS_EMP AS (SELECT EMPNO, SALARY+BONUS FROM EMPLOYEE)
DEFINITION ONLY;
• SQL0153N The statement does not include a required column list. SQLSTATE=42908
• CREATE TABLE AS_EMP AS (SELECT EMPNO, SALARY+BONUS AS PAY FROM EMPLOYEE)
DEFINITION ONLY;
• Allow you to override column names or select specific columns
• CREATE TABLE TABTEMP (ZIP) AS
(SELECT ZIP_CODE FROM TABLE1) DEFINITION ONLY;
• Can populate data directly into new table but beware of logging!
• CREATE TABLE TABTEMP (ZIP, STATE) AS
( SELECT ZIP CODE, STATE CODE FROM TABLE1
WHERE DIVISION =19
) WITH DATA ;
19. SQL Extensions
• OFFSET Extension in FETCH FIRST Clause
• SELECT LASTNAME FROM EMPLOYEE OFFSET 5 ROWS FETCH FIRST 5 ROWS ONLY;
• CREATE TABLE AS_EMP (DEPARTMENT, LASTNAME) AS
(SELECT WORKDEPT, LASTNAME FROM EMPLOYEE
OFFSET 5 ROWS FETCH FIRST 10 ROWS ONLY ) WITH DATA;
• You can also limit the number of rows that are used in a subselect.
• The FETCH FIRST n ROWS ONLY and OFFSET clause can also be specified using a
simpler LIMIT/OFFSET syntax.
• LIMIT x OFFSET y = OFFSET y ROWS FETCH FIRST x ROWS ONLY
• SELECT LASTNAME FROM EMPLOYEE LIMIT 5 OFFSET 5;
20. Regular Expressions
• DB2 11.1 introduced support for regular expressions.
• Regular expressions allow you to do very complex pattern matching in character strings.
• REGEXP_FUNCTION(source, pattern, flags, start_pos, codeunits)
• SELECT STATION FROM CENTRAL_LINE WHERE REGEXP_LIKE(STATION,‘Chennai');
• Symbol ‘^’ can be used to force the match to occur at the beginning of a string
• Symbol ‘$’ can be used to force the match to occur at the end of a string
• match more than one pattern
• SELECT STATION FROM CENTRAL_LINE WHERE REGEXP_LIKE(STATION,'way|ing');
• Result = (Ealing Broadway, Notting Hill Gate, Queensway, Barkingside)
• Match pattern zero or more times,
• SELECT STATION FROM CENTRAL_LINE WHERE REGEXP_LIKE(STATION,'(ing)*.(way)');
• Result = (Ealing Broadway, Queensway)
• The following example checks for station names that begin with the letter P-R
• SELECT STATION FROM CENTRAL_LINE WHERE REGEXP_LIKE(STATION,'^[P-R]');
• Result = (Ruislip Gardens, Perivale, Redbridge)
21. BLU Sort Processing Enhancements
• DB2 11.1 includes sort innovations, PARADIS, from the IBM TJ Watson Research
division.
• PARADIS is an efficient parallel algorithm for in-place Radix sort.
• parallel sort
• able to sort compressed and encoded data
• More efficient and improved performance as processing is performed within the BLU engine.
• The access plans will show what part of the processing is done in the row engine vs the BLU engine.
• All parts below the "CTQ” evaluator are done in the BLU engine.
• More details on PARADIS can be found in the IBM Research Paper:
• http://www.vldb.org/pvldb/vol8/p1518-cho.pdf
22. Compatibility Features with Other Database Vendors
• Outer Join Operator
• In DB2 11.1, the outer join operator is available by default and does not require the DBA to turn on Oracle
compatibility.
• Oracle keyword: "(+)“appears in the WHERE clause and refers to a column of the inner table in a left outer
join.
• SELECT DEPTNAME, LASTNAME FROM DEPARTMENT D, EMPLOYEE E
WHERE D.DEPTNO = E.WORKDEPT (+);
In DB2 11.1 limit of CHAR has been increased to 255 from 254.
DB2 11.1 introduces two new binary data types: BINARY and VARBINARY.
• INT2, INT4, INT8, FLOAT4, FLOAT8 these datatypes can be used while table creation,
but If you describe the contents of a table, you will see the DB2 types displayed, not these
synonym types.
23. DSMTOP
• DSMTOP is replacement of DB2TOP
• dsmtop -d sample -n localhost -r 50000 -u payusr
• Very lightweight, low overhead, text only.
• Monitoring accomplished by using mon_get table functions not old snapshots so lightweight
• Can monitor DB2 10.1 and above, even if u not on 11.1 u cam download it and use.
• Now includes metrics for
• BLU
• PURESCALE
• Workload management
• REORG is covered now
• Win Platform is supported
• Also additional easy menus for fresh DBA’s
• Provides Sessions, Running SQL, Top Consumers, Time spent. All these are very useful for debugging perf
bottlenecks.
