DB2 z/OS Visual Explain Plan | New Features - Version 16.0 | Aqua Data Studio | AquaClusters
This knowledge exists in the Db2 for z/OS Optimizer Development team. You can use the EXPLAIN statement to determine the access paths for the such as IBM® Data Server Manager and related Db2 Tools for z/OS® solutions to Jul 15, 2012 DB2 10 for z/OS Explain Table Conversion required!

Air quality sensors Mbed OS was chosen as the operating system and it is a free, open-source embedded operating system sensors from TEOM signal, but it does not explain how the relationship is due to the "valuetype":"DB2.5",.
implement a DB2 database. use stored procedures and triggers. resource serialization, locking and concurrency; use DB2's security and authorization mechanisms to control access to the DB2 data. use DB2's Explain facility to view and optimize DB2 data access paths. use the DB2 Catalog to monitor database performance.
The course describes and explains in detail the components, utilities and procedures involved in data and system backup and recovery, together with the various methods of utilising them to ensure maximum availability. This course is applicable to all Db2 for z/OS environments, up to and including Db2 11 for z/OS. Much of the class will be in workshops where the participants will code and review queries, execute Db2 Explains, and perform analysis on the information. Many of the workshops have the participants rewrite and/or apply tuning statements to existing queries in order to get them to perform more efficiently.

DB2 Commands and Features: Apart from the obvious DB2 group restart or IPL any type of RUNSTATS is poison to the DSC! • RUNSTATS TABLESPACE will delete any statements that use any object within the TABLESPACE regardless of any TABLE (xxx.yyy) syntax. • RUNSTATS INDEX will delete statements that use that index.

2018-04-18 EXPLAIN has been with us from nearly the start of Db2 (DB2 V2R1 when the b was B!) and, over the years, the number of Explain tables has mushroomed up to 20 in Db2 12. Not *all* of this data is really useful but there are bits and pieces that are well worth adding to your standard repertoire of explain queries! Table of contents.
This is done with an entry in the cfg file (db2390.cfg) - see the explain entries near the bottom. This course examines and explains the critical factors that affect Db2 for z/OS performance from a systems perspective. The effective use of monitoring and tuning tools is an integral part of all tuning topics throughout the course. This course is appropriate for Db2 for z/OS environments up to and including Db2 12 for z/OS.

If you do, you might be one of those who likes to retrieve access plan information by querying the PLAN_TABLE into which DB2 inserts rows when a SQL statement is EXPLAINed (either dynamically via the EXPLAIN statement or, for embedded static SQL, as part of the program bind process when EXPLAIN (YES) is included in the BIND command); or, you might prefer to view EXPLAIN data in the form of an access plan graph generated by a tool such as IBM's Optimization Service Center for DB2 for z/OS

DB2 z/OS Visual Explain Plan | New Features - Version 16.0 | Aqua Data Studio | AquaClusters DB2 for z/OS: Thoughts on History and Archive Tables I'll state up front that I'm using the terms "history table" and "archive" table not in a generic sense, but as they have technical meaning in a DB2 for z/OS context. Themis instructor Linda Claussen takes you through the "extra" information you get as part of an Explain in DB2 11 for z/OS. The EXPLAIN functionality of Db2 for z/OS, by which the query optimizer's access path determinations are externalized, has been around as long as I can remember, and Db2 people, by and large, are familiar with the concept.
