Prerequisites, installing, and running CAS on a Windows server

Learn about the Configuration Auditing System (CAS) prerequisites, and how to install the CAS agent on your database server.

Prerequisites on Windows

Before you install CAS, make sure that Microsoft .NET 4.5 or later is installed. After .NET is installed, approximately 2 GB of disk space is required for CAS.
Note: If .NET is not already installed, Guardium automatically installs it. In this case, .NET requires an additional 5 GB of disk space.

Installing CAS

Use one of the following methods to install CAS:
  • From the Windows installer wizard. To install CAS directly from Windows, browse to the directory where you download the .zip file, extract the file contents, double-click Setup.exe and follow the instructions.
  • From the command line interface, as described in Installing CAS from the CLI.
  • From the Guardium Installation Manager (GIM) as described in Installing CAS with GIM.

Reconfiguring JAVA_HOME (JVM) location for CAS

In most cases, the installation program takes care of finding the JAVA_HOME value. This value is placed in the CAS configuration file.

If for any reason (for example, you install a new Java™ version after the Guardium CAS product is installed), you need to change the location of JAVA_HOME (JVM), use the following procedure.

  1. Locate and open the CAS configuration file for editing. The full path name of the configuration file is <installation directory>/cas/conf/casclient.cfg.
  2. Within the configuration file, locate the [RUNTIMELIB] section, and change the value of the JVM directory (JVM=C:\Java\jre\bin\classic\jvm.dll).
  3. Save the file and restart the CAS service (service name: casclient or display name: IBM Security Guardium Change Audit System).
