Hey John,

I consider myself lucky for the time spent together. It all started when we first met in SVL (STL in those days). You were on an assignment in Performance if I remember correctly, I was 'the customer in B350 :-)'.

After that came the occassion where we worked together on Db2 healthchecks, etc. Was is Sweden or Denmark where we had to settle for a dinner at McDonalds because all else was closed. In the same region, the acronym SBS got a whole new meaning for me. If you don't remember, ping me.

The most valuable lesson I learned from you was while working together on a real life PIT recovery of a whole Db2 production environment. Will never forget it. 

And finally the great discussions we had during the many zBLC face-to-face meetings.

John, I owe you a lot.... Thanks for everything

IBM Db2 for z/OS Date Gate 2.1 introduces a new major feature — Query Acceleration.

Why is this big news and what does it mean? For those familiar with IBM Db2 Analytics Accelerator for z/OS (IDAA), the ability to accelerate analytical queries that target Db2 for z/OS data by routing to IDAA has been game changer. Support to accelerate analytical queries by routing to Db2 Data Gate, enables cloud-native applications that depend on business critical Db2 for z/OS data to send queries from Db2 for z/OS through Data Gate to Db2 Warehouse in Cloud Pak for Data in the private or public cloud.

The target database, IBM Db2 Warehouse is optimized for analytics. Applications always connect to Db2 for z/OS to execute queries, all result sets are also returned back to Db2 for z/OS, making query acceleration and execution completely transparent to the client application. This allows to achieve improved application performance with minimal to no changes required to the application itself, which is a key differentiator.

Not familiar with Db2 Data Gate? Learn more about it and how it is cloud enabling Db2 for z/OS data here.

Note: Query acceleration has been available as a Beta feature within IBM Db2 for z/OS Date Gate 2.0 since 2021.

Technical details

The query acceleration functionality is only supported when Db2 Warehouse has been configured as target database during the provision of Db2 Data Gate. If the feature is enabled, the character encoding of the target database will be kept the same as the encoding on Db2 for zOS (EBCDIC). This ensures that a query routed to Db2 Warehouse to be accelerated delivers the same result set as when executed by Db2 for z/OS.

1*1gWsB_F55hWZKwhWme9iQg.png

Setting up Data Gate for Query Routing

  1. Provision Data Gate with Query Routing enabled

To use the query routing feature with Db2 Data Gate, the first step is to select a Db2 Warehouse instance that is pre-provisioned on the Cloud Pak for Data platform and then enable the “Use this data gate instance for query acceleration” checkbox.

1*uj_qxC3sVNf7cGkz4QjzCw.pngEnable query acceleration when creating an instance

2. Set up Db2 for z/OS for query acceleration

The following zPARMs have to be set to enable query acceleration when Db2 for z/OS subsystem starts:

ACCEL=AUTO

Additionally, you can define what queries can be routed by setting QUERY_ACCEL_OPTIONS. An example setting is:

QUERY_ACCEL_OPTIONS=(1,2,3,5,6)

3. Connect Db2 Data Gate to Db2 for z/OS source database

1*qN_zYpjzyWHJUA9E9EcvwQ.png

4. Manage query acceleration for Db2 Data Gate

1*WO39iJPktDfDJ8Q7weaBzg.png

5. Add tables from Db2 for z/OS to Db2 Data Gate

1*uancdn7S407fHJt1aYoSWg.pngT

6. Load data from Db2 for z/OS to Db2 Data Gate and enable acceleration 

When adding the tables to Data Gate, users have the option to also load data and enable data synchronization. If this option is not exercised, then data load can be initiated from the table list on the Tables tab. Once the data load is complete, query acceleration can be enabled from the same location for the selected tables. 

7. Get information about queries being accelerated

Once query acceleration is enabled on Db2 Data Gate instance level and on table level, queries targeting Db2 for z/OS can be accelerated to Db2 Data Gate (to execute against the data in the backend Db2 Warehouse). Similar to the IBM Db2 Analytics Accelerator for z/OS, this is enabled by using the SET CURRENT QUERY ACCELERATION ALL statement:

1*BV5HaWxCvXAsjEjrMlZ_-Q.png 1*EWEsDpLsEEG9FI4Ka1G0Dg.png

After the query is executed, corresponding monitoring information will be displayed in the Queries section of the Data Gate User interface.

Db2 13 and IBM z16 – Better Together

Sometimes, things are just meant to be.  Downtime is the enemy of a business. It costs both time and money and can have grave consequences for organizations that are not sufficiently prepared, sometimes resulting in irreparable brand damage, public confidence, and trust. Analyst reports demonstrate that downtime costs $5,600 per minute on average. This results in average costs between $140,000 and $540,000 per hour, depending on the organization. Db2 13 increases resiliency with the exploitation of system recovery boost, which helps improve restart performance and minimize downtime. Db2 can exploit the IBM z16 hardware as follows:

  • New System Recovery Boost (SRB) in IBM z16 can help improve Db2 for z/OS restart performance, thereby minimizing downtime
  • Better insights to tune Db2 performance in data sharing environments with the exploitation of IBM z16
  • Expanded SORTL instruction usage based on machine learning on the amount of storage and the number of records being sorted, requires IBM z15 or higher
  • Exploits IBM z16 optimization to speed up training and query

 All this adds up to enhanced efficiency and differentiating business value for organizations.

Database Management and Upgrades - Simpler and Easier than ever Before

With all the benefits and capabilities, Db2 13 can help improve an organization’s time to value, enabling organizations to exploit new features and functions designed to avoid impacting availability, security, or performance. Organizations can enjoy the simplified process to upgrade to Db2 13 in a single phase. There is improved ability for Independent Software Vendor (ISV) products to better support data replication environments through the ability to write decompression dictionaries to the Db2 log – along with improved performance through enhanced REORG INDEX and the collection of real-time and historical information regarding utility executions.

 

Your Next Steps

This blog highlights just some of the key capabilities, benefits, and features of what IBM Db2 13 for z/OS has to offer organizations as part of their Journey to AI. It should hopefully remove any doubts as to why to upgrade from earlier versions.

In this blog we will discuss about the Capture Query environment and performance data functionality that is supported by IBM Db2 Analytics Accelerator for z/OS (IDAA) to gather query environment information to help understand and address query performance issues. With query acceleration being the primary business value proposition for IDAA it is always important to understand the environment in which the query is executing to help achieve optimal query performance .  The need for a robust means to gather information about the environment in which queries execute is amplified in the case where complex, resource intensive, analytical queries are being executed on the IDAA. 
 
Since versions 7.5.1 and 7.5.3 of the IDAA server, this new capability to allow Capturing query environment and performance data has been supported. As you may be aware, IDAA uses a Db2 Warehouse columnar engine as the datastore. When eligible for acceleration, Db2 for z/OS sends the queries over to IDAA for execution. In case of performance issues, collection of query environment and performance data can be enabled. When enabled, the queries need to be re-executed under the covers to gather the necessary information.  
 
Initiating the data capture can be done by invoking the ACCEL_CONTROL_ACCELERATOR with the following inputs or using the existing Data Studio interface to administering IDAA.

Since the query is executed under the covers and may be long-running, the timeout value here allow users to control how much longer the query will be allowed to execute to capture environment data.  This execution of the query along with performance tracing enabled will utilize Db2 Warehouse resources and may potentially impact performance of other IDAA operations, depending on the nature of the query.

Once the capture has been initiated, saving the trace with the option to also gather the Manually collected trace information will combine the query and performance trace data as part of the downloaded traces to allow users to analyze and share with the support teams for further analysis. 
 
This doc along with the default IDAA trace can help provide actionable steps to resolve the query performance problem. Some examples include, but are not limited to the following:
 
This can also be automated in a batch process using the sample stored procedure ACCEL.GET_QUERY_HISTORY2 How to store Db2 query history in a Db2 for zOS table . With GET_QUERY_HISTORY2 running at a set interval, i.e. every 5 minutes, a batch application can set a threshold for total elapsed time. For queries that exceed this threshold call ACCEL_CONTROL_ACCELERATOR automatically to collect the query environment data and performance docs.

 version="1.0">
    <getAdditionalSupport planID="0" traceCommand="CDE_PERFORMANCE_TRACE"
     timeoutInMinutes="0"/>
</aqt:controlCommand >


Then at another interval (every 24 hours), call ACCEL_CONTROL_ACCELERATOR to save the trace .

Read Now: IDUG President's Letter March 2022

Hello again to our IDUG members all over the world. I know that everyone in the Db2 User community is really excited about 2022. In addition to our plans to return to face-to-face IDUG events this year, this will be a very big year for Db2!

Of course, we hope to see you in person at our Db2 Tech Conferences in Boston and Edinburgh. But if you participated virtually in the 2021 IDUG EMEA conference last December, you already know what will make 2022 so special. IBM will be announcing a new release of Db2 for z/OS this year!

It has been five years since the announcement of Db2 12. And with the announcement of continuous delivery and regular new Db2 functions and features on demand, many of us wondered if there was going to be any "major” releases from IBM ever again. But the world changed with Data Fabric and AI, when the wants and needs of Db2 users everywhere grew so rapidly.  

IBM Db2 Vnext for z/OS will deliver significant innovations and capabilities around:

  • Innovative integrated AI approaches to developing and deploying AI insights within applications
  • Infusing AI to improve operational efficiency and reduce costs
  • Enhanced resiliency, efficiency, and application stability for unparalleled availability
  • Synergy with IBM z16 for enhanced efficiency and differentiating business value
  • Simplified database management and upgrades to help accelerate feature adoption and time to value

I have three opportunities for you to consider to bolster your career development and to enhance your effective utilization of Db2 in 2022 and beyond:   

1-Send in an abstract here to present at the 2022 IDUG EMEA Db2 Tech Conference in Edinburgh, Scotland.

2-Follow IDUG in your favorite social media channels (FacebookLinkedInTwitter) to receive registration information soon for the 2022 IDUG NA Db2 Tech Conference in Boston, USA (and other upcoming IDUG events across the globe).

3-Register here to join the IBM announcement webinar called “Db2 Vnext AI Infused with Data Insights – A Critical Component of Your Data Fabric Strategy” on April 6, 2022, from 11:00 AM – 12:30 PM Eastern Time.   

IDUG is honored to support and strengthen everyone in this community by providing the highest quality education and services for Db2. Until next time—wherever you may be reading this—stay healthy and stay safe.

Introduction

A long time ago (in a galaxy far, far away), I began this series with the intention of blogging about using Jenkins to orchestrate some tasks on z/OS. I did an introduction to Jenkins and one on groovy pipelines

 

In this blog post, we’re going to look at what we need to do to run a Jenkins node on z/OS. It should be noted that this runs as a process in USS, and we’re going to assume that you’re comfortable there. In many ways, this is a regular Posix Unix environment, albeit with extensions to reflect the fact that we’re running as part of z/OS.

Tablespaces: where exactly is my data?

By Mark Gillis

This should be pretty straight-forward: you can look in the TABLES System Catalogue and find references for the data (TBSPACE), Indexes (INDEX_TBSPACE) and Large Objects (LONG_TBSPACE). But DB2 throws a few curved balls here; partitioned tables (where the data, indexes and LOBs can be in multiple tablespaces), particular types of index that don’t seem to be in the catalogues at first glance, etc. Let’s see if we can put something together that shows the complete picture.

 

Overview

I’ve got a little database with all sorts of weird and wacky objects. It’s tiny, in terms of volume, but includes row and column-organized tables, range-partitioned tables, MQTs and a bunch of other stuff. Some tables have the full “INDEX IN … LONG IN ….” Tablespace definitions but don’t actually use them, some don’t have any or all the tablespace directives. I want to be able to see the full picture, so how do I go about that?
