Configure Your Operating Systems

Before you run the CA UIM installer, configure the operating systems for the servers that will host the CA UIM environment.

If you have questions regarding which operating systems are supported with CA UIM, refer to the Compatibility Support Matrix.
General Operating System Prerequisites
The systems you are installing CA UIM on 
require
 x64 (64-bit) architecture.
All your servers do not require the same operating system.
This section includes the following information:
  • Java on VMware Virtual Machines 
  • Java Runtime Environment (JRE) Requirements  
  • Firewalls and Virus Scanners
  •  Localization Requirements 
  • Swap Space Requirements  
  • Timezone Requirements  
Java on VMware Virtual Machines
Review the VMware 
Enterprise Java Applications on VMware - Best Practices Guide
 available at http://www.vmware.com/resources/techresources/1087 (not affiliated with CA Technologies).
Java Runtime Environment (JRE) Requirements
The UIM Server installer contains the proper JRE version for CA UIM. If you are installing UIM Server on a system where another JRE is already installed, we recommend removing the existing JRE. Running multiple JRE versions on the same system can cause issues in your CA UIM environment.
Firewalls and Virus Scanners
Before you install CA UIM:
  1. Shut down any antivirus software.
  2.  
    (Optional)
     Shut down your firewall. While not always necessary, this action maximizes your chance of a successful installation. If you keep your firewall running:
    • Ensure the port between the CA UIM system and the database system is open.
    • Specify a starting port during CA UIM installation (the recommended default is port 48000).
    • Ensure that an adequate range of ports are open (for example, ports 48000 through 48020). At a minimum, the first three ports assigned (controller, spooler, and hub) must be open. The port that is used for the distsrv probe communication is dynamically assigned.
  Restart the firewall and anti-virus software when installation is complete.
Localization Requirements
If the system is set to a language that is not English, the following error message appears during installation: 
 
The database does not exist or could not be created.
 
To prevent this error, execute:
export LC_ALL=locale
 
Locale
 is the appropriate locale string (for example, 
Norwegian
) for your language.
Swap Space Requirements
The system must be configured with either:
  • 4 GB of swap space (minimum)
  • 6 GB or more of swap space (recommended for optimal performance and reliability)
This requirement applies to both the CA UIM system and the Unified Management Portal (UMP) system.
Timezone Requirements
For data time-stamping to work correctly across a distributed UIM deployment, the UIM Server, the UMP server, and the UIM database server must all be set to the same time zone, regardless of the geographic locations of the servers.
POSIX-Oriented Operating System Prerequisites
The /etc/hosts file on your system must map:
  • 127.0.0.1 to localhost
  • The system IP address to its hostname
Linux-Specific Prerequisites
The standard C++ Library must be present.
The installer verifies that the minimum version requirement is met.
For some probes, the 
compat-libstd
 library is also required.
 
Security-Enhanced Linux
 
Security-Enhanced Linux (SELinux) is a Linux feature that supports access control security policies. While shutting down SELinux before installing UIM Server is not always necessary, doing so maximizes your chance for a successful installation. 
If SELinux status is enabled, a 
Current mode
 of 
permissive
 is acceptable. Disabling SELinux entirely is an even safer approach.
If you must run UIM Server in SELinux 
Enforcing
 mode, add the CA UIM shared libraries to a safe list. After you install CA UIM, execute:
chcon -f -t textrel_shlib_t /<UIM_install>/hub/libldapssl.so.0 chcon -f -t textrel_shlib_t /<UIM_install>/hub/libldapsdk.so.0 chcon -f -t textrel_shlib_t /<UIM_installn>/hub/libldapx.so.0
 
UIM_install
 is the directory where CA UIM is installed.
 After installation, CA UIM cannot function correctly in SELinux 
Enforcing
 mode until you add the CA UIM shared libraries to the safe list.
RHEL 7.4
If you are using RHEL 7.4, ensure that either the fonts local.conf file is configured or the dejavu-serif-fonts package is installed. For more information, see the RHEL Documentation.
 
Option 1
: The fonts local.conf file is configured. Create the /etc/fonts/local.conf file with the following contents:
<?xml version='1.0'?> <!DOCTYPE fontconfig SYSTEM 'fonts.dtd'> <fontconfig> <alias> <family>serif</family> <prefer><family>Utopia</family></prefer> </alias> <alias> <family>sans-serif</family> <prefer><family>Utopia</family></prefer> </alias> <alias> <family>monospace</family> <prefer><family>Utopia</family></prefer> </alias> <alias> <family>dialog</family> <prefer><family>Utopia</family></prefer> </alias> <alias> <family>dialoginput</family> <prefer><family>Utopia</family></prefer> </alias> </fontconfig>
Option 2
: Run the yum install command to install the dejavu-serif-fonts package.
yum install dejavu-serif-fonts
Windows-Specific Prerequisites
The hub message queue is stored on disk and is constantly undergoing read and write activity. Because disk compression reduces I/O performance, CA UIM does not support compression on Windows.
This section includes the following information:
  • Administrator Privileges
  • Microsoft Windows User Account Control
  • Write Privileges on Windows Server 2008
Administrator Privileges
UIM can only be installed by a user with administrator privileges.
 
Follow these steps:
 
  1. In Windows, open 
    Administrative Tools
     > 
    Services
     
  2. Right click on the Nimsoft Robot Watcher and select 
    Properties
    .
  3. Select the 
    Log On
     tab. 
  4. Select the 
    This account
     radio button.
  5. Enter the account and password for an administrator.
Microsoft Windows User Account Control
Windows platforms newer than Windows XP and Windows 2003 use User Account Control (UAC). UAC prevents unauthorized modifications to your computer system. 
If UAC is turned on, administrative privileges are required for CA UIM installation. 
 Although we do not recommend it, you can turn off UAC. See your Windows documentation for details.
Write Privileges on Windows Server 2008
Write privileges are required for writing to the UIM program folder (default is C:\Program Files (x86)\Nimsoft) after installation. If you log in as a user without administrator privileges after installation, you must manually set these write privileges.
