Finally, business as usual. After our February board meeting in Orlando, the election of IIUG board and our conference in San Diego we are back to our routine. For me it is mainly searching for content. I would love to get some help from you guys. Technical articles, thoughts, requests and comments on anything you would like to see in the Insider and is not there. So business as usual does not mean we are relaxing.

Informix is doing better although not at the pace we would like to see.

Towards the bottom of the Insider there is a list of blogs. Please take a few minutes to visit them. There is lots of valuable information in them.

Looking forward to meeting you in our 2013 conference wherever it will be.

Actually Using Smart Sensors and Other Time Sensitive Data with TimeSeries

The single largest source of information does not come from people or the Internet – it is from sensors such as GPS devices on moving vehicles (buses, trains, trucks, cars), smart meters for utilities and all kinds of remote sensing equipment. Their use and the data they produce is not an incremental increase, it is exponential. At the Consumer Electronic Show this year, Wi-Fi-on-a-chip for less than $4 became a reality. The end result is even more remote devices will be able to send their data to collection points for use and analysis. From a database perspective, that’s billions of new data rows to be administered, queried and analysed. From an administrative perspective, how do you load this volume of data? How is it queried efficiently to produce timely results that have real business value? What is the cost in disk and other computing resources to store and access this type and volume of data? TimeSeries technology from IBM is the answer to these and other issues when using time sensitive data.

Join us for a free, one-day hands-on-lab experience to test-drive IBM’s TimeSeries technology. There is no pre-requisite knowledge needed to be part of this one-day experience. The labs take place in the local IBM office and upon registering; you will receive the logistics for the test drive.

Turning Data into Knowledge at the Speed of Thought

Netflix states that 75% of their viewed videos are chosen based on their recommendation engine to their members. They tell us what we think we will like – and it works. Do you want to this level of foresight into your business? Challenges abound in today’s business environment. From unpredictable consumer spending and increased competition to rising costs and employee attrition, organizations of all types face considerable challenges to achieving growth across traditional and new channels while trying to deliver great customer experiences. Most organizations already have most of the data they need to respond to changes but it’s locked up “in the warehouse” where it takes minutes to hours to get answers back to any question. Would you like your organization to be able to access data as fast as they can think of the question! Then the next question! and the next? Would you like to ask questions any time of day or night without having to wait for rebuilds to occur? Is it important that this speed and functionality be at a price point that won’t break your budget? Join us for a free, one-day hands-on-lab experience to test-drive IBM’s Warehouse Accelerator that utilizes in-memory, columnar technologies. Warehouse Accelerator technology has a proven track record of providing hundreds to thousands present improvement in query performance. It produces answers in seconds or less without the penalties associated with current BI technologies. There is no pre-requisite knowledge needed to be part of this one-day experience.

The labs take place in the local IBM office and upon registering; you will receive the logistics for the test drive. Memory speed is measured in nanoseconds. Come and find out how that translates into offering performance and concurrency like never before.

Optimizing Informix database access
http://www.ibm.com/developerworks/data/library/techarticle/dm-1203optimizeinformix/index.html
Normally access to an Informix database can take from less than a second up to some expected period of time, depending on the database operation. Sometimes it can take much longer than you expected due to many reasons, such as the network speed, system performance, system load, and so on. In the worst scenario, the Informix client may be blocked forever for the expected server response that never comes. This article explains how to interrupt an SQL or connection request that is requiring more time than expected in order to improve the performance of your Informix database application.

Fastest Informix DBA Contest 2012 – How did they do it?

Please join the Fastest Informix DBA Winner Andrew Ford, Lester Knutsen and Art Kagel at 2:00pm EST on Tuesday, June 19th, for a Webcast to share with other Informix users how the winners achieved their results. Learn about the tips and tricks the real Fastest Informix DBA’s used to achieve their remarkable performance.

Advanced DataTools is pleased to announce our latest Fastest Informix DBA Contest that was held at the 2012 IIUG Informix Conference, April 22-25,2012 in San Diego, California.

Congratulations to Andrew Ford, the Grand Prize Winner of the new Apple iPad and the Fastest Overall Informix DBA. Andrew’s results were almost three times faster than the next closest contestant’s results. This year the contest was run on an Apple Mac Mini Server, using Informix Enterprise 11.70.FC4. The server is very small and inexpensive, 1.4 inches by 7.7 inches square. The CPU is an Intel Core i7 with 4 cores, and includes 8GB of RAM, and it has two disk drives, one for the application and one for the database. It is amazing to see 1,000 user sessions running on this little box and to achieve the level of throughput that Andrew accomplished. The goal of the contest is to see who can optimize an Informix database server running 1,000 OLTP users in under one hour and generate the most transactions per minute. Andrew generated over 57,000 transactions per minute. We used the Open Source BenchmarkSQL Java program to generate the transactions for this contest. The BenchmarkSQL is a JDBC benchmark that closely resembles the TPC-C standard for OLTP. It is a Java program that generates 1,000 sessions doing inserts, updates, and deletes against the Informix database server.

Connection Level Optimization

I will reiterate few existing features in Informix which you can use for optimize the connection to database. It is always an expensive operation when establishing a connection to a database. The goal should be that applications perform as many operations as possible while connected to database. Following are some connection attributes that can be used to tune application performance by reducing the network traffic:

 

  • Bulk insert optimization (SQL_ENABLE_INSERT_CURSOR)
    Create an insert cursor is a good idea to efficiently insert rows into a table in bulk. You need to set the SQL_ENABLE_INSERT_CURSOR attribute with SQLSetStmtOption(), then call SQLParamOptions() with the number of rows as a parameter. An Insert cursor creates a buffer in memory to hold a block of rows. The buffer receives data from the application program; once bugger is full data send to the database server in a block. The buffer reduces the amount of communication between the program and the database server. As a result, the insertions go faster.
  • Automatically free a cursors (AUTOFREE)
    In general, when an application uses a cursor, it usually sends CLOSE and FREE statements to the database server to de-allocate memory. Execution of these statements involve round trip of message requests between the application and the database server. The Automatic free feature (AUTOFREE) reduces the number of round trips by one. You can use the IFX_AUTOFREE environment variable or SQL statement SET AUTOFREE to enable this feature.
  • Optimize message transfer (OPTMSG)
    This feature allows you to minimize message transfers between the database server and application. Application can optimized message transfers by chaining messages together and even eliminating some small message packets. You can enable this feature by setting OPTMSG environment variable at application side.
  • Open fetch close optimization (OPTOFC)
    Application uses DECLARE and OPEN statements to execute a cursor, each statement involves a round trip of message requests between the application and the database server. The open-fetch-close optimization (OPTOFC) reduces the number of round trips network traffic. With this feature, the OPEN statement from application does not open the cursor immediately. Instead, it saves any input value that was supplied in the USING clause of the OPEN statement. Next time along with the FETCH statement it sends this input value. The database server opens the cursor and returns the first value in this cursor. Once database server reaches the last value of an open cursor, it automatically closes the cursor after it sends the data to the client application. You can use the OPTOFC environment variable to enable this feature.

 

I just provided some touch point here, there are several other way to improve network and connection to database. Please check the Improve Application Performance in Informix Infocenter for details.
