Running process: _tix.exe

Hello,

Today, I was contacted by the infrastructure guys asking me about a process running on the SAS server (Windows based). There are 2 processes "_tix.exe", one consuming more than 350Mb of Memory and the other high on CPU usage. The only information that I found was on the following link (http://ftp.sas.com/techsup/download/hotfix/HF2/R/R02/R02001/xx/wx6/R02001x6.html) talking about a hotfix. I would like to know if someone knows what does this process does and if this is normal.

Thanks

Hello,

this process is main part of SAS Information Retrieval Studio and the SAS Search Interface.

SAS Information Retrieval Studio is a framework and graphical administration interface for crawling, normalizing, analyzing, indexing, and searching text documents. It serves as the default user interface to SAS Web Crawler and SAS Search and Indexing, and provides integration with other products including SAS Content Categorization and SAS Sentiment Analysis.

The process taking high CPU is "normal", because tix.exe historically tends to take as much free cpu resources as possible (it should not block the other process, just taking more or less cpu, as required).

Anyway, before the application of that hotfix, I would recommend you to check the status of the SAS IRS, because to me it seems that IRS is requiring or trying to rebuild constantly your indexes, therefore some services might not be working properly:
