Collecting Data for an Informix Server performance issue on AIX platforms

Question & Answer


Collecting data for general engine performance problems with Informix Dynamic Server on AIX. Gathering this information before calling IBM® support helps familiarize you with the troubleshooting process and saves you time.


Collecting performance specific information for versions 11.70.xC1 and later

In versions of the Informix Server engine 11.70.xC1 and later ifxcollect can be used to gather diagnostic information without utilizing the script. To gather performance specific information execute the following command while experiencing performance problems:

$INFORMIXDIR/bin/ifxcollect -c performance -s general

Executing ifxcollect will create a tar file in $INFORMIXDIR/isa/data that can be uploaded to IBM for review. The format of the file is ifxcollect.<timestamp>.tar. Uploading the file can be accomplished using any of the methods described in the "Submitting information to IBM Support section".

For additional information on ifxcollect see the following link:

Collecting information for versions prior to 11.70.xC1

For all versions of Informix Server prior to 11.70.xC1, gather the following information for any problem:

MustGather: General Information to collect for Informix Family product problems

  2. Rename to
  3. Make executable
  4. Execute while experiencing the performance problem. Use the sh shell

Note: There are similar articles specific to Linux, HP-UX, and Solaris platforms.

Comment from customer:

"need to specify what information is sent to IBM, as the details are not spelled out, I could send the complete PERFORMANCE file, or do I send iostats.out?"

This from the script....the results should be in a zip or gz
file. Maybe on some systems the zip or gz is not running.
Customer should have specified. There should have been an error.
