1) Editorial

Once upon a time, there were many forums in the IIUG member’s area.

As time passed forums became irrelevant. Products that were no longer used or lack of interest.

Finally, the only active forum left was IDS.

Due to changes in our Web technology, we can no longer support this forum.

The new home for Informix forum is now is the IBM community site http://www.iiug.org/community

We are happy to be part of the Data and AI user community and thank IBM for hosting our forum.

This is the place to find Informix technical content and to have your questions answered by the best Informix professionals.

Pleas follow the link register as a forum member and start participating.

By doing so, you are helping yourselves, the Informix user community and Informix.

Although posts may lose their relevance over time we are planning to import, the posts form the IDS forum so you can feel at home and find what you need.

Please visit this site to vote for your favorite enhancements and place new requests.

As you can see it is a new RFE site is friendly and has a nice look and feel.

Informix pure .NET Core driver

We need pure .NET Core driver. Currently we have to compile our programs with flags for 32 or 64 bit code which is against the idea of .NET Core portability. Also it leads to errors when we sent assemblies to incorrect environment.

Driver on OpenShift platform (“light containers”) is a joke – it is heavy (180M) causing long time of deployment.

Enhance EXPLAIN in order to no longer need Informix server access

Currently Informix EXPLAIN generates a server side file. For developers that are working from remote machines, it becomes problematic to retrieve the explain files when they have restricted access to the Informix Server machine.

There are 2 undocumented functions that can be used but they have limited functionality : ifx_explain and bson_explain .

These functions return the optimizer plan, but cannot return a statistics section ( the sql statement is never actually executed, so there is no statistics section ).

Informix should be enhanced to allow a remote client to retrieve the output of the EXPLAIN plan and the statistics section.

Such capability would greatly benefits developers that have restricted access do the Informix server machine, has it happens in many corporate environments.

Add dbschema to Informix CSDK

Developers have the Informix Client SDK installed on their workstations / application development machines.

There is the need to be able to dump the Informix databases schemas definitions, but the SDK does not provide any such tool.

To work around the issue, we have to either use 3rd party tools, give the developers shell access to the Informix server or install the server binaries on the developer machines.

If the dbschema tool is bundled in the Informix Client SDK, the need for the workarounds is avoided.

dump query plan from queries in Statement Cache

Provides the ability to produce a query plan from any query that exists in the Statement Cache. Once a query is in the cache, there may be some question if it was cached with the proper query plan. Since there is no current way to confirm this, we now have a way to view the plan.

IF NOT EXISTS should not be saved as part of stored routine source

When creating a stored procedure or function with the IF NOT EXISTS optional clause included, the option text is currently included in the saved source code for the procedure. This is not true of any other database object created with the IF NOT EXISTS clause included!

This should be changed such that the optional clause is removed before saving the procedure source code in sysprocbody.

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

SQL interface to obtain the temporary space usage (tables, hash, sorts…)

A DBA and possibly a programmer needs an easy way to monitor who is responsible for the temporary space usage.

Currently it’s possible a user may be consuming a lot of temporary space and impacting other sessions, without the DBA being able to quick and easily identify the session responsible.

Other reports (from IIUG mailing list) and another RFE (36245) mentions the need for programmers to be able to find out the current session’s temp tables (onstat -g ses shows this).

The definitive solution for this should be an SQL interface showing:

– session ID

– object name

– object type (explicit temp table, implicit temp table, hash join, sort …?)

– used space

– chunk/dbspace being used

– owner nam

– ??? (PID and others, but probably thos can be gathered with joins)

This should supersede RFE ID 36245 and this includes the request for that RFE and more.

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.

5.1 Video on how to use the new 14.10 installer

With the release of IBM Informix v.14.10, there is a significant change to how Informix is installed and migration occurs across different editions. Instead of separate binaries for each Informix edition, there is a single universal binary but edition specific license files which control which features are enabled. This allows customers to download one binary bundle and use it throughout their enterprise. With the appropriate license file, customers can select which edition to activate or can easily change editions without extensive downtime or having to re-install the entire system potentially overwriting critical files. This short video by Carlton Doe explains how this new installation process works.
