Which Cognos files need to be excluded from a virus scan?

Question & Answer


Question

This document explains which files and folders need to be excluded from automatic file virus scanning

Cause

Anti virus programs can affect performance of Cognos, however there is no documentation discussing specific configurations.

Answer

You must have all anti-virus software turned off during install of Cognos BI products, or the installation may fail.

Ensure that the following files and folders are excluded:

Configuration
<c10_location>\configuration\
Example c:\Program Files\ibm\cognos\c10_64\configuration\
Exclude files of type:
*.ini
*.xml
*.xsd
*.xslt

The configuration folder is a tree structure with several levels.Exclusions should apply to the folder levels and any other subfolder level below.


Temporary files
<c10_location>\temp\
Example c:\Program Files\ibm\cognos\c10_64\temp\

The temp folder is used by Cognos BI to store temporary files used for local operations or cached data. Files in this folder don't have any extensions. Files can be differentiated based on their prefix, ex: 'uda*'. The recommendation is that the entire folder and subfolder structure is excluded
from access scanning.

You can inside Cognos Configuration set the environment value for TEMP files to something else than default - if you set to d:\temp you must exclude that folder also from the anti virus scan software.


Bin and Bin64
<c10_location>\bin and <c10_location>\bin64

All files.

The bin and bin64 folder is a tree structure with several levels.Exclusions should apply to the folder levels and any other subfolder level below.

cgi-bin
<c10_location>/cgi-bin/

cognos.cgi files

These files are needed to run the IBM Cognos 10 server.


Transformer Cubes
Example c:\Cubes\Current\
File types to exclude: *.mdc

The cubes folder is divided into various sub-folders with different levels. Exclusion should apply all folder levels below.


Log files
<c10_location>\logs\
Example c:\Program Files\ibm\cognos\c10_64\ logs\
File types to exclude:
*.log
*.xml
*.lck
*.pid
*.service
cbs* (Note: exclude on prefix, the 'cbs*' files does not have extensions)

The logs folder is also a tree structure with different levels below. Exclusions should apply to all levels below.

Runtime-models
<c10_location> data\
Example c:\Program Files\ibm\cognos\c10_64\data\
File types to exclude:
*.rtm
*.lck
The runtime models folder is a tree structure with sub-levels. Exclusions should apply to all levels below.
