    Message Level Encryption (MLE) allows your Clients to encrypt upstream data using a combination of an RSA public/private key-pair and an AES session key.
  - Changing the Client Icon
    By default, the icon in the upper left corner of the client UI is the BigFix logo.
  - Client UI main actions
    The BigFix Client UI is used to display message boxes to the end users logged on to the client computer (including pre-action messages, action running messages, and restart/shutdown messages).
  - Optimizing the servers
    BigFix operates efficiently, with minimal impact on network resources.
  - Optimizing the consoles
    To be responsive, the console requires reasonable CPU power, memory, and cache space.
  - Managing Bandwidth
    File downloads consume the bulk of the bandwidth in a typical installation.
  - Managing Downloads
    BigFix uses several methods to ensure that downloads are efficient and make the best use of available bandwidth.
  - Creating custom client dashboards
    You can create custom Client Dashboards, similar to those in the console.
  - Geographically locating clients
    Because clients are often deployed in remote offices, it is useful to create a property that lets the clients report their own location. You can create a location property in BigFix using the Location Property Wizard.
  - Locking clients
    You can change the locked status of any BigFix client in the network.
  - Editing the Masthead on Windows systems
    You can change the default parameters stored in the masthead by using the BigFix Administration Tool.

    You can replace the passwords on the server with obfuscated passwords, by indicating the type of password that you want to replace and the new password.
  - Modifying Global System Options
    To modify a few basic system defaults, such as the minimum refresh time and the Fixlet visibility perform the following steps:
  - Extending the BigFix License
    When you first request your action site license, you are issued a license for a specific period of time.
  - Re-creating Site Credentials
    Private and public key encryption creates a chain of signing authority from the BigFix root down through the Site Administrator and including each console operator.
  - Creating special custom sites whose name begins with FileOnlyCustomSite
    You might delete special custom sites whose name begins with FileOnlyCustomSite that are generated to propagate files to agents accidentally or purposely, for example, when performing a gather reset. You can recreate them by using the PropagateFiles.exe tool.
  - Configuring Client CPU Utilization
  - Customizing Client UI message strings
    You can customize the Client UI message strings. It is possible to alter the English text output and also to change any of the localizable string translations by using the XLAT files for the Client UI.

Increasing the size of the FillDB buffer directory

The FillDB buffer directory temporarily stores reports from the clients before they are stored into the database.

By default the directory is full if it contains 3MB of files or if it has more than 10,000 files. The consequence is that the information is not sent to the BigFix server quickly, and it might be a severe problem.

You can configure the FillDB buffer directory and the maximum number of hold files by performing the following steps:

On Windows systems:

Add the following keys to the registry path HKLM\Software\Wow6432Node\BigFix\Enterprise Server\PostResults:

BufferDirectoryMaxSize

It defines the maximum size of the FillDB buffer directory, in bytes. The default value is 3MB.
Note: Do not increase this value over 20MB without specific guidance from HCL Support.

BufferDirectoryMaxCount

It defines the maximum number of files allowed in the FillDB buffer directory. The default value is 10,000.
Restart the FillDB service.

Note: On Windows systems, if you are adding these keys to a BigFix relay and not to a BigFix server, the registry path where to add them is HKLM\Software\BigFix\Enterprise Server\PostResults.

On Linux systems:

Add the following lines to the /var/opt/BESServer/besserver.config file:
```
[Software\BigFix\Enterprise Server\PostResults]
BufferDirectoryMaxSize = <SIZE_IN_BYTES>

[Software\BigFix\Enterprise Server\PostResults]
BufferDirectoryMaxCount = <MAX_NUMBER_OF_FILES>
```
where:

BufferDirectoryMaxSize

It defines the maximum size of the FillDB buffer directory, in bytes. The default value is 3MB.

BufferDirectoryMaxCount

It defines the maximum number of files allowed in the FillDB buffer directory. The default value is 10,000.
Restart the FillDB service.
