Informix Dynamic Server (IDS) has emerged as the de facto standard
Established 20 years ago by the Ministry of Finance of the Government of Jamaica, Fiscal Services Ltd. has a mandate to insure the compatibility of information systems across several revenue collecting agencies. It provides a wide range of information technology services including infrastructure and software development. With approximately 250 employees, the company has frequently moved Ministry of Finance offices using manual processes into the information age.
In 1993, when Lorenzo Grant, the managing director, arrived, he determined that Fiscal Services needed to modernize its own approach. "We needed to have a database management system and tools," he said. After an extensive analysis, the company determined that the Informix Dynamic Server (IDS) was the best platform for their needs.
Grant opted for IDS for several reasons. Perhaps the most compelling was the price/performance and price/capability ratio. "Based on what we needed to do, we thought it was the best deal around," Grant said.
In addition to price/performance, IDS had several other key features. Since the telecommunications infrastructure in Jamaica is typical for the Caribbean, and many government agencies operate regionally, "we have to make sure that the different regions can operate independently but we have to be able to synchronize the databases," Grant said. "IDS is way ahead in that regard."
Furthermore, IDS diagnostics are useful in pinpointing performance and applications problems. And, Grant noted, the database "pretty much runs itself. The DBAs just need to monitor it." Once the initial sizing parameters are set, there is little need for continuous monitoring. "IDS is very good in terms of administration," added Sujit Sakar, a project manager at Intelligroup, a worldwide consulting company that has worked extensively with Fiscal Services. Finally, IDS offered the best support services in the region and was willing to work hard to understand both Fiscal Services' needs and its clients' needs, helping to develop solutions.
The first IDS implementation was developed for the Stamp Office, which is responsible for transfer taxes when property and estates change hands. "They did not have any reconciliation between their documents and transaction processes with the funds collected." Grant said.
Working with the Intelligroup, Fiscal Services used IDS and the Informix development suite to put the appropriate automated systems in place. Now in its third version, revenue collected has increased sharply even though the number of transactions has remained steady. Moreover, the reports developed allowed managers to track events and provide better, quicker service to their customers. "They were quite pleased with that," Grant said.
Customs Office Project
From that success, Grant and his team launched a project to automate the processes associated with the Customs Office. Ultimately, the operation went from a completely manual system to one in which brokers and importers can complete their financial transactions online.
Originally developed with a client-server architecture, the application has been moved to a three-tier architecture using WebSphere running on an IBM pSeries server. "We just replaced the front-end tier based on the application requirements," Sakar said. The database layer remained the same. The system has around 1000 users and the response time has been outstanding, Sakar added.
IBM and Informix
Fiscal Services was also a long-term customer of IBM, so when Informix came under the IBM umbrella, "we saw that as confirmation that we had made the correct choice," Grant said. "IBM's resources and commitment to Informix means that expertise would be more available and at a lower cost."
The list of projects running on IDS is long. Indeed, Grant observed, the entire financial management system of the Government of Jamaica runs on the IDS platform. In total, Fiscal Services is operating close to 100 IDS instances with close to a terabyte of data. With some legacy systems still running, Fiscal Services is running several IDS versions. Fortunately, said Sakar, "They don't take much management. They are almost completely self-healing."
Fiscal Services is currently working on a tax portal funded by the Inter-America Development Bank, as well as a one-stop shop for services that importers and exporters typically complete through a myriad of governmental agencies like licensing and inspections.
Given the large number of successes, IDS has become almost the de facto standard for government agencies in Jamaica. "We want to take advantage of the experience we have," Grant said. "And, it works from a cost perspective."
Grant has set his sights even wider. "We are the largest user of IDS in the region. We are embarking on sharing our software and services to others," he said. "Many of the applications and procedures are similar in other governments in the region. This is an inexpensive way for them to come up to speed."

The Southeast Informix Users Group (SEIUG), based in Atlanta, GA, and the Washington Area Informix User Group (WAIUG) based in Washington, DC, are teaming up to present Informix User Forum 2005, the premiere Informix regional user group technical conference in the eastern U.S.
The Informix User Forum, previously sponsored biennially by WAIUG, has long had a reputation for excellence in both value and technical content. Now, the two groups have joined forces to evolve the Forum into an annual two-day conference. This year's event will be held December 8-9 in Atlanta.
Forum 2005 promises to provide even more technical content, plus opportunities to network with fellow users and access to information on the latest vendor offerings. This, combined with a registration fee of US$ 50.00 for the entire conference, makes the value of this event hard to beat.
Call For Presentations
We are currently accepting presentation abstracts for the Forum on Informix-related topics in any of the areas listed below. Subjects related to all current Informix and Informix-heritage products are welcome, as well as products that operate in those environments such as other IBM products, plus third party, Open Source and cross-platform products.
Presenters will receive a complimentary all-conference pass.
The Forum will be organized into three general subject areas or tracks that will run concurrently.
The Application Development track will cover such topics as application development tools and methodologies, application and database architecture, and maximizing application and SQL performance.
The Database Engines and Administration track will feature sessions on topics including database and data warehouse design and administration, performance tuning, backup and restore, and security.
The Informix Edge track will contain talks on aspects of Informix that provide a distinct edge in application development and processing such as emerging technologies like XML and Web services, operation in cross-platform and heterogeneous environments, and support for Open Source and third-party tools.
Tracks will feature extended session lengths of 70 minutes, which conference goers have said they prefer.
Visit the Forum 2005 Web site http://www.iiug.org/~seiug/forum2005/ to find more details about the conference and an on-line application for submitting your presentation abstract.
The deadline for submitting presentation abstracts is August 15, 2005.
There are also a limited number of vendor sponsorship opportunities available. Please contact Lester Knutsen or Walt Hultgren for more information.
Whether you're interested in speaking or simply attending, we think you'll find that the Informix User Forum 2005 will continue the tradition of providing extremely high quality and dense technical content at very low cost. Visit the Forum site for more information. We hope to see you in Atlanta December 8-9!
Mark Scranton is continuing his tour across the U.S. educating our local user groups. As you can see from the following list it is a great success.
I am a great fan of Informix. I started my career with IDS 7.0 and was developing applications using Informix-4GL for about 3 years. I was also handling the DB server for about a year though I cannot claim to be a full fledged DBA which I always wanted to be. I have drifted away from Informix products now due to the rarity of it in the market and the practical difficulty of low job market ;) I still believe that Informix DB engine is the strongest of all though I am outdated with all new releases of Informix products. I am very happy to see that Informix is in a come back trail when we all sadly believed that it will be phased out by IBM.
Thanks & regards,
Is there any general script or logic for resetting or shuffling all the existing serial values in a table so as to avoid all the holes and get room for new numbers in the sequence? For example, suppose that IDS must renumber the customers table in the stores database because the maximum customer number is now in danger of overflowing. What algorithm would work there?
Note that a single table could have multiple cross-references to a serial column; I don't think that complicates things.
Note that by virtue of the assumptions above, all updates would either not alter the serial value (8a) or would decrease it (5). Consequently, there will not be any non-trivial collisions between the old number sequence and the new number sequence. This means that the updates in 8c will be safe - there is no risk of changing any Snew value twice.
Does that cover the bases? The algorithm in step 8 is messy, not least because the set of tables to be changed has to be determined on the fly (the most dynamic of dynamic SQL), and also because of the issues raised in step 11 (in the most general case; in the particular case of the customers table, you probably don't have to worry about that).
Problem (2005-07-15) - Step 8b runs foul of multiple unique constraints on the table, which means that you can't insert the new row. The provisional solution is to lock the table to prevent access by anyone else; defer all the unique constraints (except, perhaps, the constraint on the serial column); do the updates; re-enable the unique constraints.
If there's anything else I've left out, please let me know.
Background: Praveen Ghantasala asked a variation of this question in an email sent on 2003-12-05; Jonathan Leffler responded with a variation of this answer on 2003-12-08.
The Informix(r) Dynamic Server 9.x (IDS 9.x) supports multiple methods to create unique identifiers. The original method is to use the SERIAL type with a unique constraint. IDS 9.x adds the SERIAL8 type that is an 8-byte integer value that virtually gives an unlimited number of identifiers. With the use of a unique constraint, the SERIAL8 can virtually provide unlimited number of unique identifiers. Both SERIAL and SERIAL8 are specific to a given table.
As of IDS 9.4, we can also use a SEQUENCE object to generate an identifier that can then be used in any table in the database. This virtually insures a unique identifier for any table within a database as long as the generation is done through one specific sequence.
With the raising popularity of distributed systems and collaboration between corporations, there is a need for the generation and manipulation of identifiers that are guaranteed to be unique worldwide. This can be done with the help of the operating systems capabilities to generate a Globally Unique Identifier (GUID) and the use of an opaque type that can manipulate the GUID.
This article describes the implementation of a new data type that represents a GUID. This includes a User-Define Routine (UDR) that generates a GUID with the help of the operating system.
