The IIUG board of directors met in Atlanta July 31 to August 2. To be more precise we met at the Atlanta Sheraton. We hardly left the hotel. As usual we reported to the board on the status of our tasks, planned our future meetings and conference calls, made plans and set action items to our regular activities: The IIUG Informix conference, The IIUG Insider, Our Web site, Our survey, The SIGs, The LUGs, Sponsors, The IOD conference. We also met wit Christy Maver who is in charge of IBM Data Management Communications, Barbara Benis who is in charge of IDS sales and Adam Gartenberg who is in charge for DM social marketing. Meeting IBM executives enables us to influence IBM and offer our help.
We usually try to maintain and improve our regular activities. Once in a while we start something completely new. In 2005 we partnered with IDUG and offered our membership an Informix conference. In 2008 we took another step and made our own IIUG Informix conference. It was a huge success. The conference was sold out. I highly recommend the IIUG Informix Conference 2009. We increased the capacity but there is a good chance we will be sold out and will not be able to accommodate the demand. So the sooner you register the better.
At the Atlanta meeting we decided to go Web 2.0. It will not happen at once. But you will gradually see it. The main platform will be our Web site but the Insider too will take a step forward giving you searching and voting capabilities and becoming more interactive.

Using VERCOLS to eliminate lock contention
The plague of application developers everywhere is lock contention. Articles on the subject are all over the tech media. With the common accessibility of multi-core processors, now even applications designed to reside on a single user desktop machine have to contend with locking issues as concurrent programming becomes a reality. As multi-user database application developers, the Informix community, and most database developer communities, have always had to deal with these issues. Some database vendors have dealt with the issue by avoiding it. They added row versioning and other schemes so that multiple users can view and update data without contention. But there is a cost to those schemes in that they do not scale well in the database engine and increase storage requirements.
The approach taken in all Informix versions from SE through Turbo, Online and Dynamic Server has always been to provide low cost locking and lock wait mode and to depend on developers to reduce contention between users and between applications through intelligent programming. This usually means implementing Optimistic Locking Protocols. Most WEB developers have become familiar with this term, but I am always surprised at the number of non-WEB developers who have never heard of the concept and rely on pessimistic locking to resolve concurrency issues. Now that IDS is once again being recognized as a force in the RDBMS industry, we are going to be seeing more and more developers who have always taken the easy way out and are not familiar with the problem or the solution. Fortunately IDS v 11.50 has added a new feature known as VERCOLS that directly supports high speed, low overhead, implementation of optimistic locking. But I’m getting ahead of myself. Let’s start with a review.
Pessimistic vs. Optimistic Locking
Pessimism or optimism in this case refers to the assumption that the application (or the application developer I suppose) makes about whether concurrent updates to a single record or set of related records is possible or common. If you are assuming that any row that your application is about to update may have already accepted a competing and possibly conflicting update between the time you read the row and the time you commit the transaction then you are being pessimistic. If you assume that concurrent updates are unlikely then you are being optimistic. Being optimistic is not the same as being stupid however, there’s a difference. In many places it is the law that traffic has to stop when a pedestrian begins to cross the street. The pessimistic pedestrian waits for the traffic signal to change and all of the cars to come to a complete stop before leaving the safety of the sidewalk. The optimistic pedestrian waits for a significant gap in the traffic and looks carefully before beginning to cross and keeps his eyes wide open for trouble. Meanwhile the immensely stupid pedestrian steps out into traffic with his eyes firmly planted on his iPod watching a bootleg copy of the XFiles movie.
Best case, the optimistic pedestrian gets across the street first, worst case, if there’s a lot of traffic, he’s alongside the pessimistic pedestrian. Our immensely stupid pedestrian, well you can guess.
Many real-world business applications do not require pessimistic locking protocols. As an example, in an insurance claim tracking application it is unlikely that two case workers will be updating the same claim status concurrently. This is because in most insurance claims departments claims are assigned to individual claims clerks, so no one else is likely to be updating a claim but the assigned processor. Is it possible? Sure, a supervisor reviewing a claim may be making a notation on the case at the same time that the assigned processing clerk is entering an invoice from a service provider or an update from the claimant. Generally old work-flow rules that used to require a clerk to remove the file from the filing cabinet when beginning to work on it are still maintained in some form in today’s digital world.
The question is do we need to lock the case in order to work on it? The pessimist says, “Of course. Then only one person can update the case at a time and there are not problems. Data consistency is guaranteed.” The optimist says, “Not when I start working on it. I can lock the case just before I save my changes and check to make sure that no one else has modified the records I’m updating.”
What’s wrong with the pessimistic approach? In an RDBMS environment like IDS that lock may prevent other users from accessing other cases also as table scans and index leaf scans will encounter unrelated locks preventing them from continuing. And all heck breaks loose if a user pulls up a record for update and gets a long telephone call or goes out to lunch or home for the day without closing the record and releasing his locks.
What’s wrong with implementing the optimistic approach then? Until IDS 11.50, implementing optimistic locking required one of three strategies:
Compare data merging results:
- After gathering updates from the current user, refetch the original data under a lock and compare.
- If there are no changes to the original data or only columns other than the ones the current user modified have been changed, apply the current changes to the new version of the record, update, and commit.
- If columns that the current user modified were also changed by another user, reject the current changes and present the updated data to the user to try again.
- After gathering updates from the current user, refetch the original data under a lock and compare.
- If there are no changes apply the current changes to the new version of the record, update, and commit.
- If there are any changes by other users reject the current changes and present the updated data to the user to try again.
Validate a timestamp or version only.
- After gathering updates from the current user, refetch only a timestamp or version column from the updated row(s) and compare to the original.
- If the timestamp or version is the same apply the current changes to the new version of the record, update, and commit.
- If the timestamp or version is different reject the current changes and present the updated data to the user to try again.
The first two strategies require fetching the original data twice and comparing many or even every column of data between the original copy and the refetched copy to insure that the data was not modified by another user. This is time consuming and complex to program properly and in the compare and merge strategy the data merging may not be simple to implement requiring checking interrelationships between columns that were not modified by either user. The last strategy is simple to implement in application code, but more complex within the database. One has to include the timestamp or version number validation column in all tables and implement a default and an update trigger for that column so that the value will always correctly indicate the row’s status. That’s where 11.50 comes in.
IDS 11.50 introduces the concept of VERCOLS. You can CREATE TABLE…. WITH VERCOLS; or ALTER TABLE …. ADD VERCOLS; either of which creates two hidden or shadow columns (that are not included when you use asterisk [*] in a projection list) ifx_insert_checksum and ifx_row_version in the table which are automatically populated when a row is inserted. Also the ifx_row_version column is maintained for you by the IDS engine by being incremented each time the row is modified. This feature was added to support redirected writes from secondary servers in the IDS 11.50 MACH11 feature set and resolve possible update conflicts from multiple secondary servers. However, application developers can also take advantage of the ifx_row_version to simplify optimistic locking. All you have to do is to fetch ifx_insert_checksum and ifx_row_version along with the other data from every table you may be called upon to update. Then after gathering changes from the user, you simply begin a transaction, refetch the ifx_insert_checksum and ifx_row_version columns, and compare their contents to the original values you fetched the first time. If the checksums and versions are all the same, you can proceed to safely update those rows. If not, reject the updates with a message to the user identifying the problem, and let the user start all over again. You have to verify both shadow columns because the ifx_insert_checksum is not changed once the row is inserted but it is guaranteed to be different even if two rows are inserted with identical values in all columns and the ifx_row_version is always one (1) when a row is first inserted. Checking ifx_insert_checksum detects whether a row has been deleted and reinserted with the same key values and ifx_row_version detects whether a row has been updated in place.
> insert into art_test values (1, "Hi"); 1 row(s) inserted. > select *, ifx_insert_checksum, ifx_row_version from art_test; one two ifx_insert_checksum ifx_row_version 1 Hi -507554221 1 1 row(s) retrieved. > delete from art_test; 1 row(s) deleted. > insert into art_test values (1, "Hi"); 1 row(s) inserted. > select *, ifx_insert_checksum, ifx_row_version from art_test; one two ifx_insert_checksum ifx_row_version 1 Hi 1402964547 1 1 row(s) retrieved. > insert into art_test values (1, "Hi");insert into art_test values (1, "Hi"); insert into art_test values (1, "Hi"); 1 row(s) inserted. 1 row(s) inserted. 1 row(s) inserted. > select *, ifx_insert_checksum, ifx_row_version from art_test; one two ifx_insert_checksum ifx_row_version 1 Hi 1402964547 1 1 Hi 1862247411 1 1 Hi 694147363 1 1 Hi 339734675 1 4 row(s) retrieved.
Notice that the deleted and reinserted rows have different ifx_insert_checksum values as do the three rows added later, even though all five rows contained the identical data for the columns one and two.

IIUG Expects to Sell Out Again at the Second Annual IIUG Informix Conference
IIUG (International Informix Users Group, (http://www.iiug.org) is an organization of volunteers dedicated to the Informix community. Following a record-breaking conference that boasted the largest single gathering of Informix sessions and vendors under one roof since IBM’s purchase of it, the group is planning to repeat this successful event.
August 18, 2008 (CIO) Ubuntu is well known in user circles as the cool kids’ Linux. It’s available preinstalled on PCs and laptops from Dell Inc. and from numerous smaller computer vendors. What Ubuntu hasn’t been known as is a Linux distribution that matters to CIOs and IT managers. Things are changing.
By this, Yates explained, “we want to make it as easy to install software on the Ubuntu server as it is to install the Ubuntu desktop. For example, we’re getting ready to release DB2 and Informix database management systems that come as DEB packages, which will install and do basic set-up with only a couple of clicks or a single command line instruction.”
IBM expands Lotus Notes Mac support to iPhone
AppleInsider – IBM betting on Apple
Support for the iPhone in Lotus Notes is only IBM’s latest step in investing in Apple’s platforms as a competitive alternative to Microsoft’s Windows. An AP report from January cited IBM spokesman Mike Azzi as noting that his company has “a lot in common” with Apple. “We’re going to cross-pollinate,” he said.
Earlier this year in May, IBM released its Informix Data Server 11 for Mac OS X Server. And over the course of the last year, multiple groups within the company have launched pilot programs aimed at evaluating support for migrating to Apple’s Mac computers within the company.
An initial study at IBM Research, which started in October of 2007, found that 86% of those participating wanted to keep their MacBook Pro laptops over returning back to IBM ThinkPads running Windows. “It has been easier learning the Mac than learning Vista,” one participant reported. IBM has since expanded its Mac pilot program.
