- Introduction
  BigFix aims to solve the increasingly complex problem of keeping your critical systems updated, compatible, and free of security issues. It uses patented Fixlet technology to identify vulnerable computers in your enterprise. With just a few mouse-clicks you can remediate them across your entire network from a central console.
- BigFix Platform Unicode Support Overview
  BigFix Platform V9.5 gathers data from BigFix clients deployed with different code pages and languages, encode the data into UTF-8 format, and report it back to the BigFix server.
- Sample deployment scenarios
  The following deployment scenarios illustrate some basic configurations taken from actual case studies. Your organization might look similar to one of the examples below, depending on the size of your network, the various bandwidth restrictions between clusters and the number of relays and servers. The main constraint is not CPU power, but bandwidth.
- Requirements and assumptions
  BigFix runs efficiently using minimal server, network, and client resources.
- Types of installation
  Before you install the product, decide if you want to do an evaluation or production installation.
- Managing licenses
  You must obtain a license key before you can install and use BigFix.
- Before installing
  Before running the installation make sure that you read the following topics and run the requested activities if needed.
- Installing on Windows systems
  Now that you understand the terms and the administrative roles, you are ready to get authorized and install the programs.
- Installing on Linux systems
  After understanding the terms and the administrative roles, you are ready to actually get authorized and install the programs.

Removing the Product Components on Linux systems

You can have one or more BigFix components installed on a local system and you can decide to remove one or all of them at the same time.

About this task

To uninstall one or more BigFix components installed on a local Linux system, run the following steps:

Procedure

Look for the installed BigFix RPM packages by entering the following command:
```
rpm -qa | grep BES
```
Remove the Server, the WebUI, the Client, and Web Reports RPM files:
```
rpm -e BESWebUI
rpm -e BESWebReportsServer
rpm -e BESRootServer
rpm -e BESRelay
rpm -e BESClientDeployTool
rpm -e BESAgent
```
Note: You cannot remove BESAgent until you remove all components depending on it (BESRootServer, WebUI, and so on).
Remove the following files and folders:
Warning: If you do not plan to remove all BigFix components, keep the folder "/var/opt/BESCommon".
```
/etc/opt/BES*
/opt/BES*
/tmp/BES
/var/log/BES*
/var/opt/BES*
```
Where: BES* is a prefix followed by the name of a BigFix component, for example "BESClient".

Remove the BFENT and BESREPOR local databases:

su - db2inst1 
db2 drop db BFENT
db2 drop db BESREPOR

or the BFENT and BESREPOR remote databases:

su - db2inst1 
db2 attach to TEM_REM user <UserName> using <Password>
db2 drop db BFENT
db2 drop db BESREPOR
db2 detach
db2 uncatalog node TEM_REM
