Welcome to the International Informix Users Group (IIUG) Insider! Designed for IIUG members and Informix user group leaders, this publication contains timely and relevant information for the IBM Informix community.
October looks like it was ages ago. Since the last Insider we had war, once again, in our region. I hope it is the last one but find it hard to believe.
The vNext EVP is on its way. Those who are participating are aware of the great improvements. The rest will need to wait until it is GA. I hope it will be announced at our conference. One more reason to come. Registration is now open.
Looking forward to meeting you all in San Diego.
IBM's Big Data for Smart Grid Goes Live In Texas
Last week, IBM publicized a big data project with client Oncor, the largest electricity distribution and transmission company in Texas, that delivers an advanced smart grid to help 3 million households conserve energy.
Coverage focused on the benefits of the project with local media reporting from Fort Worth Star Telegram, and industry and tech publications including InformationWeek, Smart Grid News, Green Tech Media, Inside Big Data, Seeking Alpha, Data-Informed, Utility Products and TMC Net. An IBM bylined article in Dataversity exploring how big data is transforming the energy and utilities industry was timed to run with the news.
Oncor Electric Delivery...says it is teaming up with IBM on a new data management project designed to give consumers a better look at their electricity usage. The online service works with advanced "smart" meters and other networked devices installed at homes and businesses to provide a nearly real-time monitor of consumption, the companies were set to announce today. The system also gives Oncor automatic alerts on power issues and outages. —Fort Worth Star Telegram
When IBM came on board, Oncor was expanding its project to more than 3 million advanced meters, each of which sends information every 15 minutes to Oncor's offices -- a dramatic increase over a traditional electric meter with its monthly readings. The logistics posed a classic big-data challenge. How could Oncor process and store all of that data in a cost-effective way? Oncor needed to upgrade from its relational database management system, which was efficient at managing modest volumes and velocities of data, but was too inefficient for the new smart grid. So Oncor installed IBM's Informix database software to run its smart grid. The new Informix system loaded meter data 20 times faster, and performed queries up to 30 times faster than the system it replaced, IBM claims. In addition, it reduced data storage needs by 70%, an improvement that remained linear over time and therefore allowed Oncor to accurately predict its storage requirements. —InformationWeek
IBM is a giant in smart grid big data, with partners around the world using its IT heft to link up power meters, grid sensors, leak detectors for water networks, and other end devices into the back-end systems that make them run. —Seeking Alpha
IBM and big Dallas-area utility Oncor announced the latest achievement on this long-running relationship - a big data platform that's analyzing Oncor's 118,000-plus miles of power lines, crunching data from its 3 million or so, smart meters from Landis+Gyr and meter data management software from Ecologic Analytics (both owned by Toshiba), and rolling out the results for both utility operations staff and to customers via the state's smart meter web portal. —GreenTech Media
In its big data initiative with Oncor, the largest electric delivery company in Texas, IBM points to a list of benefits... Oncor now has pinpoint access and insight into billions of data measurement points, from advanced meters and networking devices, to transmission sensors, power lines and generation plants. Many Texas households have noted a 10 percent decrease in energy usage since the implementation. — Smart Grid News

2013 IIUG Conference Planning Committee
New in DeveloperWorks
Starting with IBM Informix 11.70xC2, Informix started supporting the private installation feature. The private installation feature(non-root user installation) will allow Informix to be installed by a user other than root, and will permit the software to run without user Informix or group Informix on the machine. Inside the server, Informix will be used as the owner of the system catalog, but neither user Informix nor group Informix will have any special privileges with respect to a private server. The CSDK and other installers which are part of the Informix bundle will also permit non-root users to install the software. In this article, we discuss aspects of this feature in Informix and provide tutorials on how to manage users using JDBC, ESQL/C and ODBC drivers.

Why NOT Informix
Communication Setting Optimizations: Fetch Buffer Size
This setting applies to Informix client-server communications when using the SQLI protocol. While it can be set for other types besides TCP (shared memory or pipe), as we will see, it is only really useful for TCP connections.
When the server responds to a client request for data, it arranges the data in an buffer of the size requested by the client. The data is arranged by tuples, or rows. When the buffer is full, or the server has come to the end of the rows being fetched, the buffer is copied over the communication channel to a like buffer within the client application process memory. The client API (ODBC, JDBC, ESQL...) reads from the buffer, and copies or transforms the data into application variables as the application requests rows. When the client comes to the end of the buffer, and there is still more data in the result set, the client requests the server to send it another buffer of data.
The fetch buffer size setting is intended to allow the application to reduce the number of times the client API has to request another buffer. This setting is very much in the domain of speed versus size tradeoffs. Since at least one buffer has to be sent, there is no advantage to setting the buffer size to be larger than the typical, expected result set. Also, each buffer is associated with one executing statement; so, if there are lots of statements being processed concurrently, the size of the buffer can have an impact on the application's memory footprint.
A simple way of thinking of how the fetch buffer size affects the application performance is to think of it in terms of number of buffers per result set, times how long of an inherent delay there is between the client and server. If the result set size is small, or the communication channel has little to no delay (which is always the case with shared memory or pipe connections), there is no significant benefit to larger buffer sizes. What follows are the results of series of tests where the result set size, fetch buffer size, and network delay are varied.
These tests were written using the ODBC interface, but the pattern of results should be the same across all Informix APIs when using the SQLI protocol. The client and server are on the same physical machine, with the client running under Windows and the Informix server on a Linux virtual machine. The network delay is controlled using Linux's network emulation (netem) functionality.
The data do not actually exist in the database; they are manufactured at the time of query execution through the use of views created to multiply the base result set. This configuration is not representative of any real world scenarios. So, while the pattern of effects produced from fetch buffer size settings is reliably produced, any other metrics, such as the number of queries per second, that might be inferred should not be considered to be representative of real world performance.
The empirical results match predictions. As the size of the result set is increased, the effect of increasing the size of the fetch buffer is that slower communication between the client and the server has less effect. When sending large results to the client, it is possible to compensate for a slow network with a large fetch buffer. When the result size is small, or the network has little delay between the sending and receiving of packets, the setting of fetch buffer size has little effect.
Increasing the fetch buffer size beyond the size of the result set has no meaningful effect, across all network conditions.
Table 1. Result set 1K data
When there is a negligible network delay, the size of the fetch buffer has negligible effect. As the network delay increases, the effect of increasing the fetch buffer size becomes more significant. When the network delay is 100ms, increasing the fetch buffer can increase performance by over 6 times.
Table 2. Result set 256K data
When working with large result sets over a slow network, setting a large fetch buffer size can be crucial to performance. Notice that the data transfer rate of the largest buffer over the slowest network is only about 15% slower than the fastest condition, and 12 times faster than the same transfer using a small buffer.
Table 3. Result set 4MB data
The results above should provide a useful guide on an appropriate setting for fetch buffer size based on the actual queries being performed and the network infrastructure in use. The main drawback to a high setting of fetch buffer size is limited to when the memory footprint of the application starts to impede on memory requirements of other processes.
