Installation Guide
Learn the system requirements, licensing and installation instructions, and how to configure and maintain BigFix.
- 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 V11 gathers data from BigFix clients deployed with different code pages and languages. It encodes all data into UTF-8 format, and reports it back to the BigFix server.
- Sample deployment scenarios
  The following deployment scenarios illustrate some basic configurations taken from actual case studies.
- 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.
  - Installing and configuring DB2
    BigFix 11 Server installation on Linux has IBM DB2 as a prerequisite. It must be installed before the BigFix Server is installed.
  - Installing and configuring MS SQL
    Starting from BigFix Version 11 Patch 1, the Linux Server installation introduces the support of Red Hat 9 x86 64-bit with Microsoft SQL Server database.
  - Downloading BigFix
    Download BigFix from HCL License & Delivery Portal (Flexnet).
  - Performing an evaluation installation with DB2
    To install a BigFix server with an evaluation license on Linux with DB2, perform the following steps:
  - Performing an evaluation installation with MS SQL
    To install a BigFix server with an evaluation license on Linux with MS SQL, perform the following steps:
  - Installation Command Options
    You can run the Production or Evaluation installation in interactive or silent mode. You can use a single installer for different components.
  - Installing the components
  - Installation Folder Structure
    After the BigFix installation, you can see the following folder structure.
  - Configuration, Masthead, and Log Files
    At the end of the installation you can find the following BigFix files containing the settings of the installed components and the installation messages.

  - Changing the DB2 port
  - Removing the BigFix components from Linux
    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.
  - DSA on Linux
- Installing the clients
  Install the BigFix client on every computer in your network that you want to administer, including the computer that is running the console.
- BigFix Administration Tool
  The BigFix Administration Tool, also called BESAdmin, is the tool we use to perform configuration changes and maintenance operations.
- Post-installation configuration steps
  After having run the installation, make sure that you read the following topics and run the requested activities if needed.
- Managing relays
  Relays can significantly improve the performance of your installation.
- Introduction to Tiny Core Linux - BigFix Virtual Relay
  Follow the step-by-step sequence of operations needed to build the virtual machine, from the downloading of the ISO image to the complete setup and configuration of the BigFix Virtual Relay.
- Setting up a proxy connection
  If your enterprise uses a proxy to access the Internet, your BigFix environment can use that communication path to gather content from sites.
- Running backup and restore
  You can schedule periodic backups (typically nightly) of the BigFix server and database files, to reduce the risk of losing productivity or data when a problem occurs by restoring the latest backup.

- SQL Server parallelism optimization
  The performance of an SQL Server database instance can often be improved by small tweaks. Performance might also be hindered by simple oversights. In fact, some SQL Server parallelism settings have suboptimal default values. Moreover, they have to be re-tuned after an hardware upgrade. Other issues might arise from inadvertent hardware configurations, especially when SQL Server is hosted on a virtual machine (VM).
- Known limitations and workarounds
  This section describes the known limitations and possible workarounds.
- Logging
  This section describes the log files associated with the BigFix components.
- Uninstalling the BigFix client
  To uninstall the BigFix client installed on the various operating systems, see the following sections.

Managing the BigFix Services

Procedure to manage the services.

You can start, stop, restart, or query the status of Linux BigFix services using the service command, when available, as shown below:

service service stop
service service start
service service restart
service service status

Alternatively, for the RHEL, SUSE and derived distributions listed below:

Red Hat Enterprise Linux (RHEL)
CentOS
Oracle Linux
Amazon Linux
Rocky Linux
SUSE
OpenSUSE Leap

It is possible to use the following commands:

systemctl stop service
systemctl start service
systemctl restart service
systemctl status service

For the others Linux distributions supported by BigFix Platform, it is possible to use the following commands:

/etc/init.d/service stop
/etc/init.d/service start
/etc/init.d/service restart
/etc/init.d/service status

Note: Up to BigFix Version 11.0.1, for backward compatibility reasons, it is possible to use the commands above also to manage the services of RHEL, SUSE and derived distributions listed above.

where service can be one of the following services:

besclient
besexplorer
besfilldb
besgatherdb
bespluginportal
besrelay
besserver
beswebreports
beswebui

Note: Ensure you do not use the systemctl command to manage a service, except on RHEL, SUSE and derived distributions.

If you installed the BES Server Plugin Service (MFS), use these commands to start and stop it:

service mfs start
service mfs stop
