In September 2018, IBM announced a brand new product, IBM Db2 AI for z/OS. This synthetic intelligence engine monitors statistics entry patterns from executing SQL statements, uses machine studying algorithms to choose optimal patterns and passes this tips to the Db2 query optimizer for use by using subsequent statements.desktop getting to know on the IBM z Platform
In might also of 2018, IBM announced version 1.2 of its laptop learning for z/OS (MLz) product. here is a hybrid zServer and cloud application suite that ingests efficiency statistics, analyzes and builds fashions that signify the fitness popularity of a variety of symptoms, monitors them over time and provides real-time scoring capabilities.
a couple of aspects of this product providing are aimed toward helping a community of mannequin developers and executives. as an instance:
This laptop gaining knowledge of suite became in the beginning aimed at zServer-primarily based analytics purposes. one of the most first glaring choices became zSystem performance monitoring and tuning. gadget administration Facility (SMF) statistics which are immediately generated via the working system provide the raw facts for gadget resource consumption such as imperative processor utilization, I/O processing, memory paging and the like. IBM MLz can collect and save these information over time, and construct and train models of system conduct, rating those behaviors, identify patterns now not readily foreseen by using humans, improve key efficiency indicators (KPIs) and then feed the mannequin results again into the gadget to affect gadget configuration changes that can improve efficiency.
The subsequent step became to implement this suite to analyze Db2 efficiency statistics. One answer, known as the IBM Db2 IT Operational Analytics (Db2 ITOA) answer template, applies the computer learning technology to Db2 operational information to gain an realizing of Db2 subsystem fitness. it may possibly dynamically build baselines for key performance warning signs, give a dashboard of those KPIs and give operational personnel true-time perception into Db2 operations.
while regularly occurring Db2 subsystem performance is a crucial factor in universal software fitness and performance, IBM estimates that the DBA guide team of workers spends 25% or extra of its time, " ... combating entry course complications which trigger performance degradation and repair impact.". (See Reference 1).AI involves Db2
believe the plight of up to date DBAs in a Db2 environment. In modern IT world they must support one or greater huge data functions, cloud utility and database services, utility installation and configuration, Db2 subsystem and software efficiency tuning, database definition and management, catastrophe restoration planning, and extra. query tuning has been in existence seeing that the origins of the database, and DBAs are constantly tasked with this as well.
The coronary heart of query direction analysis in Db2 is the Optimizer. It accepts SQL statements from applications, verifies authority to entry the facts, reviews the locations of the objects to be accessed and develops a list of candidate facts entry paths. These entry paths can encompass indexes, table scans, a lot of table be part of methods and others. within the statistics warehouse and large statistics environments there are usually additional choices obtainable. One of these is the existence of summary tables (sometimes called materialized query tables) that comprise pre-summarized or aggregated statistics, as a result allowing Db2 to avoid re-aggregation processing. an additional choice is the starjoin entry course, normal within the facts warehouse, the place the order of table joins is modified for efficiency motives.
The Optimizer then studies the candidate entry paths and chooses the entry route, "with the lowest charge." can charge in this context capability a weighted summation of resource utilization including CPU, I/O, memory and other supplies. finally, the Optimizer takes the bottom can charge entry direction, shops it in memory (and, optionally, in the Db2 listing) and starts access direction execution.
large records and data warehouse operations now include application suites that enable the business analyst to use a graphical interface to construct and manipulate a miniature statistics mannequin of the information they want to analyze. The applications then generate SQL statements according to the users’ requests.
The issue for the DBA
with a purpose to do decent analytics on your distinctive information outlets you want a fine understanding of the data necessities, an knowing of the analytical features and algorithms accessible and a excessive-efficiency information infrastructure. unluckily, the quantity and placement of statistics sources is expanding (each in measurement and in geography), facts sizes are growing to be, and applications continue to proliferate in number and complexity. How may still IT managers help this atmosphere, principally with essentially the most skilled and mature body of workers nearing retirement?
remember also that a large part of reducing the whole can charge of ownership of those techniques is to get Db2 applications to run sooner and greater efficaciously. This continually translates into the usage of fewer CPU cycles, doing fewer I/Os and transporting much less statistics across the network. for the reason that it is commonly difficult to even identify which applications may advantage from efficiency tuning, one method is to automate the detection and correction of tuning issues. here's the place computer learning and synthetic intelligence can be used to splendid effect.Db2 12 for z/OS and synthetic Intelligence
Db2 version 12 on z/OS uses the computer discovering facilities outlined above to gather and keep SQL query text and entry course particulars, in addition to specific performance-related historical suggestions similar to CPU time used, elapsed times and outcome set sizes. This providing, described as Db2 AI for z/OS, analyzes and shops the information in laptop studying models, with the model analysis consequences then being scored and made attainable to the Db2 Optimizer. The subsequent time a scored SQL statement is encountered, the Optimizer can then use the model scoring information as input to its access route option algorithm.
The effect should still be a reduction in CPU consumption because the Optimizer makes use of model scoring input to opt for superior access paths. This then lowers CPU expenses and speeds utility response instances. a significant skills is that the use of AI application doesn't require the DBA to have information science competencies or deep insights into query tuning methodologies. The Optimizer now chooses the superior entry paths primarily based now not best on SQL question syntax and records distribution facts however on modelled and scored historic efficiency.
This can be especially essential if you save records in dissimilar places. for example, many analytical queries towards big information require concurrent entry to definite facts warehouse tables. These tables are commonly called dimension tables, and they comprise the information aspects usually used to manage subsetting and aggregation. as an example, in a retail environment believe a desk referred to as StoreLocation that enumerates each keep and its location code. Queries towards keep sales statistics may additionally want to combination or summarize earnings with the aid of area; therefore, the StoreLocation desk can be used through some large data queries. during this environment it's regular to take the dimension tables and replica them regularly to the big statistics utility. in the IBM world this place is the IBM Db2 Analytics Accelerator (IDAA).
Now feel about SQL queries from both operational purposes, information warehouse users and massive facts business analysts. From Db2's point of view, all these queries are equal, and are forwarded to the Optimizer. although, in the case of operational queries and warehouse queries they should most likely be directed to entry the StoreLocation desk in the warehouse. even so, the question from the enterprise analyst against huge facts tables should probably access the copy of the table there. This consequences in a proliferations of talents entry paths, and greater work for the Optimizer. fortuitously, Db2 AI for z/OS can provide the Optimizer the counsel it should make smart entry path selections.how it Works
The sequence of pursuits in Db2 AI for z/OS (See Reference 2) is generally here:
There are additionally a variety of consumer interfaces that give the administrator visibility to the popularity of the accumulated SQL commentary efficiency information and model scoring.summary
IBM's desktop discovering for zOS (MLz) offering is being used to superb effect in Db2 edition 12 to enhance the efficiency of analytical queries as well as operational queries and their associated purposes. This requires administration consideration, as you should examine that your business is prepared to devour these ML and AI conclusions. How will you measure the charges and advantages of the use of computer learning? Which IT support group of workers should be tasked to reviewing the influence of model scoring, and maybe approving (or overriding) the consequences? How will you assessment and justify the assumptions that the utility makes about entry course choices?
In other phrases, how neatly do you know your statistics, its distribution, its integrity and your latest and proposed access paths? this may examine the place the DBAs spend their time in helping analytics and operational utility efficiency.

TAMPA, Fla., April 4, 2019 /PRNewswire-PRWeb/ -- Infotel, a leading global software vendor of data performance and optimization solutions for z/OS, today announced its newly upgraded iDBA-Online product is now generally available in the United States. iDBA-Online uses Artificial Intelligence to help automatically manage the most efficient maintenance schedule for IBM Db2. This new release brings more automation to Db2 maintenance, freeing up DBA resources for increased production. Additionally, through optimization of Db2 maintenance schedules, customers are seeing reductions of 5-10 percent CPU utilization from improved administration of these tasks.
"The sheer amount of data and the maintenance needed for optimization make Db2 a volatile and ever-changing environment," said Carlos Almeida business analyst at Tampa, Florida-based Infotel Corp. "A maintenance strategy that was set at the beginning of the month may not be viable after just a few days. This solution was designed to leverage AI and task automation to alleviate the chaos of maintenance for DBAs."
Db2 maintenance is essential for performance, recoverability, and optimized system resources. But every maintenance operation has a cost in terms of CPU and I/O and often these essential duties take too much of a DBA's time, eating away at his/her bandwidth to be performing more productive and innovative tasks.
Infotel's latest U.S. product offering addresses this critical budgetary dilemma for companies on IBM z/OS with Db2 and takes the guesswork out of maintenance duties by using Artificial Intelligence to automatically schedule maintenance in the most efficient way possible. iDBA runs in the background and consumes minimal resources while constantly receiving Db2 log data to analyze the most cost-effective way to schedule backups, reorgs and other Db2 maintenance tasks. The solution uses proprietary algorithms to combine SLAs, cost benefit analysis data, and business constraints set forth by clients to establish in real time, the optimum maintenance schedule. Maintenance schedules are dynamically updated and automatically executed to ensure compliance with SLAs and certify that every single operation has a positive ROI for the overall Db2 cost category.
Being able to dynamically evaluate the impact of Db2 maintenance with the ability to change schedules is essential for streamlining maintenance operations that maximize Db2 application performance and reduce z/OS operational costs. Intelligent automation allows the system to take over Db2 maintenance scheduling so DBAs can spend less time on manual analysis and scheduling allowing them to focus on more strategic, innovative ways to solve more pressing data problems.
Automation is a key component of all products from Infotel which was founded in 1979 and was first to market with a web-to-database product that played a key role in the development of e-commerce as it is known today. Infotel has also built a wealth of automation into its other mainframe optimization product DB/IQ, which automates SQL code quality assurance, and was also recently launched in the U.S.

Infotel Corp., based in Tampa, Florida, is a software vendor and IT consulting firm specializing in data performance and optimization solutions for the Mainframe z/OS platform.

Here are the "best of the best" strategies that define a successful and competent database administrator (DBA). While I present these in the context of DB2 on z/OS, I strongly believe that they are applicable across all hardware platforms and database management systems.Standardize Database Recovery Processes
Ensure data recoverability. If there's one thing to get right, this is it. While other things (such as performance or security) may seem more urgent, ensuring data recoverability is the database administrator's most important responsibility. (For more on this, see DB2 on z/OS Recovery -- Get it Right).
Consider how the DBA begins implementing a database to support a critical production application. If a disaster occurs, will the data be available in the agreed-upon Recovery Time Objective (RTO)? If not, in the case of medical and financial data, this may breach contracts with vendors or violate audit guidelines. Data recoverability is another major consideration in some legislation. Here are some that affect financial institutions:
Most IT shops use regularly scheduled standard backup procedures (e.g., DB2 image copies), but few have actually tested the recovery time of these objects and analyzed whether their backup procedures are sufficient (or necessary) for their recovery requirements.
You should ensure you have all of the following:
Automate reactive or simple reporting processes, freeing the DBA for higher-level work. Your first reaction might be, "Wait! I'll automate myself out of a job!" Far from it. Implementing automation makes the DBA more valuable. IT management wants its knowledge workers doing tasks that add value. These might include detailed systems performance tuning, quality control, cost/benefit reviews of potential new applications and projects, and more. Management understands that a DBA spending time on trivial tasks represents a net loss of productivity.
The advantage of automation isn't merely speed; automating tasks helps move the DBA away from reactive tasks such as reporting and analysis toward more proactive functions.
Here's a typical list of processes many DBAs still manually perform:
Each of these tasks can be replaced by an automated reporting or a data gathering process of some kind. With such processes in place, DBAs now can schedule data gathering and report generation for later analysis, or guide requestors to the appropriate screens, reports or jobs. This removes the DBA from the reactive rut and generates time for proactive tasks such as projects, architecture, planning, systems tuning, and more.
Along with choosing specific tasks to automate, you'll probably need to learn one or more automation tools or languages. REXX is an example of a popular language for online or batch access to DB2 data. There are many examples and ideas for automated processes in articles, presentations, and white papers.Implement DBMS Autonomics
Implement DBMS-based processes so the system is self-healing and self-tuning. As our IT organizations have matured, we became smarter about our problems. We began to collect problem logs, and analyzed them looking for trends and patterns. We recognized frequent problems and devised strategies for automatically dealing with them or preventing them.
We've now reached the next logical step in this progression: engineering processes and process control to make systems and applications self-aware and self-healing. This is called autonomics. Autonomics, ranging from simple scripts to complicated processes, can be applied to applications, systems, or support software. For many DBAs, the idea of a self-healing database inspires visions of the database redesigning itself. What exactly would a self-healing database heal? One DB2 z/OS example that comes to mind is real-time statistics. DB2 dynamically generates these data distribution statistics. An example of their use is during execution of the Reorg utility, where real-time statistics may be queried and the results used to decide whether or not to execute the Reorg.
These and other examples of DB2 autonomics make it possible to "program in" a manner of self-tuning (or at least self-management) into the DBA's support infrastructure. Review the literature and IBM documentation for possible implementation of autonomic processes.Understand Management Needs
Give your management the data they need to measure your productivity and prioritize the team's work. IT infrastructure management can be subjective, considering the lack of good productivity or quality measures. Faced with distributing and prioritizing work across a database support team, management usually creates or extends a spreadsheet or project plan to include task categories and team assignments.
In seeking to increase productivity, management needs an important piece of information: the variability of the DBA's work. This usually translates to whether the tasks that need to be done have a fixed amount of effort and can be pre-scheduled or consist of a variable amount of work that unpredictably arrives. In other words, are the DBAs being reactive, active, or proactive?
Some work tends to have a fixed or well-known duration and can usually be easily assigned and scheduled. Other work tends to arrive at random, uncontrolled times; there may be no way to estimate the amount of effort required.
The DBA's manager assigns the fixed work (usually projects, meetings, etc.) to DBA resources at a level that allows sufficient additional available hours for important variable work, such as production issues and emergencies. In more mature environments, this may be implemented as a Gantt chart showing the next several months of resource consumption. This can be extremely valuable for estimating the availability of DBA resources for future projects, or for pre-planning some discretionary time that may be required.
This method of managing task and resource allocation dovetails nicely with the DBA efforts discussed earlier to implement automation and autonomics and define standard processes that can be easily outsourced. DBAs will work to convert variable, non-standard work into fixed, scheduled work, moving away from reactive tasks. Management will see fewer variable tasks and more fixed tasks, and more easily be able to assign DBA resources.Summary
While there are other tactical choices that may define a DBA's daily life, the strategies mentioned here are the crucial ones: they support all aspects of the enterprise's data; they support the idea of off-loading simple and repetitive work to the machine, freeing the DBA for more skill-based tasks; and they build on industry best practices such as recoverability, reliability and data availability.
Review the list and ask: Do we have these standard processes in place? Are they well-documented? Is the documentation centrally located and easily accessible? Have we done enough in each area that adds real value to our organization? The answers to these questions will assist you in determining where your time is best spent.

DB2 DBAs and application programmers are the antithesis of a match made in heaven. But we do have to love each other – if only for the fact that we cannot live without each other. Applications have very little business use without a smooth running database and vice versa.Rocky road?
So why is this relationship always so delicate? We all know the answer. While DBA’s spend their lives making sure their database is protected, always available and performs like a smoothly running Formula 1 car, to them it can feel that application programmers are doing everything to make sure all the sensors and gauges display “critical status” all the time. Conversely, developers are tasked to fuel the creation of new sleek applications faster than ever before, and they often feel that DBAs are doing everything to slow them down.
I’ve often heard statements like, “Our database would be in excellent shape if it wasn’t for these programmers writing inefficient code,” or, “My application would perform a lot better if these DBA’s would allow me to do what I think is best.” While both groups may have a point, discussions like these rarely lead to anything beneficial for either party.An olive branch?
So what if I told you that the latest DB2 releases offer numerous possibilities for programmers not only makes their lives easier but also does the same for DBAs? On the flip side, what if DBAs could actually demonstrate to development teams that some new features in DB2 can actually help them to develop and test new applications much faster?Learn from an IBM DB2 champ
On December 10 at 11:30 a.m. ET CA Technologies senior engineering services architect and DB2 champion Steen Rasmussen will explain how some of these features work and how DBAs and application programmers can benefit from using things like new DB2 Object Types, new BIND parameters, Access Path changes and more.
I attended one of Rasmussen’s sessions at the EMEA IDUG conference in Dublin last week and all I can say is that he does a fantastic job explaining some of the most complex material in a way that everybody understands: all in an effort to help DBAs and application developers to work in unison.
Please join me for a session from one of the worlds leading DB2 experts. Register for, “Community Webcast: Application Development Goodies in DB2 10 and 11 – Make your Favorite DBA Love You.”
Got any stories to share about the relationship between DBAs and app devs? We’d like to hear them so leave a comment below.
