SUSE Linux

I am currently working with someone who is in the process of moving an application written in Cache Object Script over to a Windows server. It was previously running on a Linux server so all of the paths are unix style paths. Is anyone aware of a way to have cache remap paths to different paths so this user won't have to go through all of the scripts and change them?

In older versions of Cache 2007 for example you could setup a device where the name was "/somefolder/" and the physical path was "C:\somefolder\" and that worked. However in newer versions of Cache you get <NOTOPEN> if you try to write to a device like that. I assume this was undefined behavior to begin with but it was very handy.

There are often questions surrounding the ideal Apache HTTPD Web Server configuration for HealthShare.  The contents of this article will outline the initial recommended web server configuration for any HealthShare product. 

As a starting point, Apache HTTPD version 2.4.x (64-bit) is recommended.  Earlier versions such as 2.2.x are available, however version 2.2 is not recommended for performance and scalability of HealthShare.

Have you ever thought what could be a reason why some development environment (database, language) would eventually become popular? What part of this popularity could be explain as language quality? What by new and idioms approaches introduced by early language adopters? What is due to healthy ecosystem collaboration? What is due to some marketing genius

During recent large scale benchmarking activities, we were seeing excessive %sys CPU time that negatively impacted scaling of the application.


We have found that a lot of the time was spent in the localtime() system call due to the TZ environment variable not being set.  A simple test routine was created to confirm the observation, and the elapse time differences and CPU resources needed with TZ set versus TZ not set were astonishing.  It was discovered that the inherit use of stat() system calls to /etc/local_time from localtime() are very expensive when TZ is not set.


InterSystems highly recommends confirming in any Linux installation whether x86 or Linux on Power that the TZ environment variable is set appropriately for optimal performance.  For more details see: "man tzset"
