I was planning to write a recap on the IBM Insight conference in Las Vegas. Unfortunately I was not able to attend Insight 2015 and the IIUG October board meeting. My wife is not well and I preferred to stay with her. I hope things will be better for me in the near future and I will be able to share Informix news with you again.

The IIUG Planning Committee has opened the speaker registration site for IIUG 2016. We are ready to accept your presentation proposals for this premier Informix event. The Sawgrass Marriott Golf Resort and Spa in Ponte Vedra Beach, FL will be hosting IIUG 2016 beginning Wednesday May 4th and running through Sunday May 8th, 2016.

The Sawgrass Marriott Golf resort combines contemporary accommodations and an amazing selection of dining options with a spa, meeting space, and 99 holes of championship golf over 65 acres. As a guest of the beach resort, you can enjoy access to The Stadium Course at TPC Sawgrass, one of the PGA TOUR’s most venerable courses, home of THE PLAYERS Championship and the PGA Tour Headquarters.

The IIUG Planning Committee is seeking technical professionals as well as end users from the Informix community who are interested in sharing their knowledge, expertise, and experience with Informix and how they use it to improve their day-to-day business performance. This event stands out from many other industry events of this type due to the diversity of our speakers and the information they are willing to share with our attendees.

IIUG 2016 will follow the same format as last year’s event. The first 3 days will be a series of technical and user sessions, hands-on labs and general sessions. The last day will consist of ½-day tutorials.

Presentation proposals should highlight Informix technical solutions, real world experiences and/or trade tips you want to share. PLEASE NOTE: The IIUG Planning Committee uses your proposal to determine what sessions will be presented at IIUG 2016, so your proposal should be brief but provide enough detail about your topic. Multiple presentations are encouraged. The actual presentation will not be needed until March. Speaker guidelines can be found here if you need additional information.

All selected speakers will receive a complimentary pass to IIUG 2016. This pass will include: the Wednesday night Welcome Reception, access to all sessions from Thursday through Saturday, the receptions on Thursday and Friday nights, and access to the Exhibit area. The pass does not include the Sunday tutorials, however, they can be purchased for a nominal fee.

The deadline for submitting your presentation proposal is November 30, 2015. For your convenience speaker logins have been retained for those who submitted a presentation proposal for IIUG 2015. Please submit your presentation proposal and biography today for consideration for IIUG 2016. Submit your proposal here.

If you are still unsure about speaking at IIUG 2016 or you don’t have a topic you want to present, submit your request for assistance at conference@iiug.org.

Registration will soon be open. Check out IIUG 2016 for additional information.

We look forward to seeing you at IIUG 2016.

It sounds like a paradox: SQL with NOSQL

When a DBA runs a SQL script, it is usually passed through an application interface, such as dbaccess. IBM Informix began providing dbaccess with 3.70 CSDK, so that a SQL routine can also be run on the client side. On older CSDK versions and in some operating system environments, that API option may not integrate well with other tools. A query can be run on client or server (with appropriate authentication) using the REST API with very little setup.

1. In the wire properties file, at minimum, set:

url=jdbc:informix-sqli://<ipnumber>:<tcp port#>/sysmaster:INFORMIXSERVER=<servername>;USER=informix;PASSWORD=<password>
listener.type=rest
listener.hostName=localhost
# listener.hostName=* <-(use this host if not using local loopback)
listener.port=8080
security.sql.passthrough=true

2. Tell the JRE where your configuration is:

java -jar jsonListener.jar -start -config <your.properties file>

We are ready to run. As a sample, here is a query which uses the (UNIX) curl command to fetch users, session numbers, and the database they are accessing:

curl -G “http://localhost:8080/sysmaster/system.sql” (http://localhost:8080/sysmaster/system.sql) –data-urlencode ‘query={$sql:”select username,odb_sessionid,odb_dbname from syssessions,sysopendb where syssessions.sid=sysopendb.odb_sessionid order by username”}’

Example output:

[{“username”:”informix”,”odb_sessionid”:30,”odb_dbname”:”sysadmin”},
{“username”:”informix”,”odb_sessionid”:31,”odb_dbname”:”sysadmin”},
{“username”:”informix”,”odb_sessionid”:30,”odb_dbname”:”sysmaster”},
{“username”:”informix”,”odb_sessionid”:63,”odb_dbname”:”sysmaster”},
{“username”:”informix”,”odb_sessionid”:29,”odb_dbname”:”sysadmin”},
{“username”:”informix”,”odb_sessionid”:32,”odb_dbname”:”sysadmin”}]

Note – you can substitute any valid expression (for the “…” ) in the section: query={$sql:”…”}

RFE Corner Back to top

Just in case you are not aware, some time ago IBM created a public website to collect the requests for new features directly from users. The RFE (Requests For Enhancements) website is included in developerWorks. You can access it here.

Once you logged in with your usual IBM ID, choose “Information Management” in the Brand dropdown box and “Informix Servers” or “Client Products” in the Products dropdown box.

The interesting thing is that any request, including your request, if you place one, are submitted to be voted on. This means the RFEs that receive more votes have a greater chance to be considered by the architecture and development teams for further consideration. In other words, this IS the opportunity to provide enhancement ideas even if you are not the biggest IBM customer on the planet Earth.

Some RFEs will be of great interest, others will not seem useful to you. This is why your opinion is important. Do not hesitate to vote and place comments!

The idea of the RFE corner is to provide a digest on new Informix RFEs and make those RFEs more visible and accessible for the community, so that you can vote for them in a faster and easier way. By participating actively in this website, IBM will have solid and useful elements from the customer base to introduce new functionality to Informix product.

Please also note that now on we can see the last comments of the IBM Lab about each RFE, and its status now appears clearly.

(Login at DeveloperWorks to see the RFEs.)

Do not forget to vote for one or several of those RFE’s if they fit your requirements. The more vote, the more chances that the Dev Team will seriously consider the request.

You can access each RFE by clicking on the above links. At the bottom of each RFE page you will find a hyperlink to vote for it. You will see the Request stats, including number of votes for this request, on the right side of the request page. The more votes, the greater the chance an enhancement will be addressed by the Development Team, taking into consideration the general interest.

Take some time to examine the full list and vote for the enhancements you would like to see implemented.
