The world is becoming virtual. Virtual meetings and conferences, virtual offices.

We are working from home but technology keeps going. And Informix is going forward as well.

We are looking for a successful fourth quarter and a great 2021.

The IIUG is preparing for board elections.

Stay tuned.

Backup from RSS or HDR Secondaries using ontape, onunload, onbar, dbexport

In HDR environments, being able to backup or export databases from and HDR, HDR read-only, or an RSS secondary server is critical. Programs like ontape, onunload, dbexport, and onbar generate locks on tables during backups and data-exports. This creates problems while applications and users using Informix try to use the system during backups in 24 x 7 x 365 production environments. Being able to backup or export data on secondary systems is critical for compliance and backup integrity.

Obtain the query plan of a running query

Many times a DBA is called to check upon a slow process. Most of the times those processes are running a slow query.

Sometimes it’s hard to know if the query is using the best query plan or not. A DBA can reproduce the query, but it it was prepared without values or if the statistics were changed after it started there is no guarantee that the query plan seen by the DBA is the same as the running query.

We have “onstat -g pqs” which sometimes can give us a clue, but it’s mostly cryptic and undocumented. If a user has X-Windows he can try xtree, but it’s a bit strange for todays standards.

We also have SQLTRACE, but if it was not set when the query was launched it will not capture the info (and besides, due to the circular nature of the buffer it may not be there at the time we need it).

A simple pseudo-table in sysmaster could probably implement this with ease.

It could also be extended to support the “last” query plan making it easy to get the query plan in any tool

Informix should be able to change owner on tables and any other objects

If user=informix creates all database and all tables, then programmer creates table but user=informix cannot change it. Only drop it.

Backup Individual database, not entire instance

Need a mechanism, similar to ontape, to backup a live database (as opposed to entire instance), without locking it.

5.1 Congratulations to Lester Knutsen

Lester became one of the newest IBM Lifetime Champions.

Most of us already know Lester and how much he does for Informix community.

For those of you who are not familiar with Lester and all of his accomplishments:

Lester Knutsen has been developing database applications with Informix databases since 1983. He is widely known in the Informix community for his extensive experience and teaching skills.

Lester founded Advanced DataTools in 1993, an IBM Informix Consulting, Training, Support and Tools Partner specializing in data warehouse development, database design, and performance tuning, where serves as President and Principal Consultant. He specializes in Informix performance tuning, advanced Informix training and developing very fast database systems.

He is founder and past president of the Washington D.C. Area Informix Users Group (WAIUG), and is one of the five founding members of the International Informix Users Group (IIUG).

In 2002, he was one of the first to receive the IIUG Directors award and is a member of the IBM Gold Consultant program. Lester is one of the inaugural IBM Champions, awarded in October 2008 and has maintained his IBM Champion status every year since.

Of course, in 2020, he became an IBM Lifetime Champion, which consists of the top 1/2 of 1% of IBM customers and one of only 23 individuals (three Informix uses) in the world from IBM to receive this honor.

Congratulations Lester! Well deserved!

5.3 IBM Informix is Included in the Modernization Upgrade Campaign

IBM Informix is included in the Modernization Upgrade campaign and new parts announced by IBM in July.

https://www-01.ibm.com/common/ssi/ShowDoc.wss?docURL=/common/ssi/rep_ca/5/899/ENUSLP20-0405/index.html&request_locale=en

This is designed for existing IBM Informix clients to help modernize their Informix based solutions with the IBM Cloud Pak for Data interoperable set of services. IBM Cloud Pak for Data is based on Red Hat OpenShift enterprise container platform that promises simplicity, adaptability, unified experience, governance and security. This unified platform has been shown to improve productivity, reduce risks and increase agility of data management. In the coming quarter, a certified Informix container running on the Cloud Pak for Data platform is planned to be available.

IBM Informix has been available in container form factor for several years as discussed in past IIUG events. This new offering integrates with the strategic IBM Cloud Pak for Data deployments that will bring the value of formal certification, security assessments and modern interoperable services including Watson Knowledge Catalog, Data Virtualization and AI/ML to existing Informix clients.
