UNIX Installation Considerations
Note: We recommend that you review the Release Notes of the CA Technologies
product that uses these common components, in addition to this Release Notes, before
installing the common components.
We recommend that you review the following items before you install the common
components:
■
On Linux, you must verify that the appropriate RPM packages and operating system
patches have been installed before beginning the installation.
■
The common components installer automatically determines whether to use
graphical mode or character-oriented VT100 mode.
Note: The following prerequisites are required to use graphical mode:
– JRE 1.6 or higher must be installed on the server.
– The monitor must be graphics-enabled.
– The $DISPLAY environment variable must be set to the local terminal.
■
You can disable the following common components properties, which are enabled
by default, during the Custom installation:
– Update the login scripts to set the common components environment for all
users.
– Automatically start common components whenever the server is restarted.
■
After you install the common components, you cannot change the host names.
Before you install the common components, we recommend that you verify that
the host name returned by the hostname command and the nslookup command
using the IP address match exactly.
