Apache HTTPD RC 2.2.29
User Rating: / 0

The new release of Apache version 2.2.X is v 2.2.29. Offically this version is a release candidate - but for ASF an RC is basically a pre-release build of what is to come. In other words, if the version is rejected (as version 2.2.28 was because some of the updated documentation had not been included) the version number does not change to version 2.2.29.X - instead a new verison number becomes a RC - release candidate.

HOWTO: Collect performance baseline statistics
User Rating: / 3

Use nmon as basis for performance analysis

Update: fixed syntax errors in script. The find commands were never working!

Too often I visit customers and "discover" that they have one of many condiftions that make analysis of performance very difficult. Generally there is either too little, too much, or (too) different data collected to do a proper analysis. At the end of this article I provide a script as an example of how performance data collection can be standardized. In between I discuss the reasoning for the number of collections, as well as number and duration of the samples.

Although many customers have adopted the use of nmon for collecting performance statistics their collection process is rarely standardized. When it is standardized the intended detail of data is often lost in the reports because the defaults taken or chosen are not sized right.
Perl 5.20.0 for AIX - real soon!
User Rating: / 0

I blame it all on ApacheTest Wink because I was trying to test the latest version httpd-2.4.10 and was getting lots of errors. Of course, perl-5.8.2 and perl-5.8.8 are properly ancient - while perl-5.10.1 is merely past end-of-life.

In short, I needed to do my testing on AIX 7.1 with the supported version of perl at v5.10.1. That was at least enough for the latest CPAN to load and to get the bundle ApacheTest to load.

Good news is: http-2.4.10 comes up with 0 errors - of all that were not skipped at least - AND, I nearly have perl v5.20.0 ready for trial for AIX 5.3, AIX 6.1 and AIX 7.1 - as aixtools.perl.

More news soon! Cool
