Requirements Specific to UNIX or Linux Operating Systems

This topic is part of Requirements for Installing and Configuring Siebel Enterprise Server Components.

Review the following requirements specific to UNIX or Linux operating systems:

• Verify that the network adapter is correctly configured to support full duplex Ethernet by verifying the following parameters:
  • RJ45 Port Link Status: up
  • Media Speed Selected: 100 Mbps Full Duplex
  • Media Speed Running: 100 Mbps Full Duplex
• If the set-group-id flag is used, then make sure that the installer ID is a member of the group that owns the Siebel Enterprise Server root directory.
• Installation must be performed as a nonroot user. This requirement stems from the Oracle Universal Installer software.

  Future Siebel CRM releases must be installed as the same user who installed the base release.

  For more information, see Setting Permissions and Ownership.

  See also Configuring the Siebel Gateway Name Server for Automatic Start and Configuring the Siebel Server for Automatic Start.

• On UNIX operating systems, when you install Siebel server modules into a mount point location, you must do so into a directory that is at least one level down from this location.

  For example, given the mount points /export/home or /export/siebel, you must create a new directory under either of these directories, in which you will install the Siebel Enterprise Server or Siebel Web Server Extension (SWSE). For example, you might create a directory named siebel and then install into /export/home/siebel or /export/siebel/siebel. Installing directly into the mount point location, such as /export/siebel, might create significant problems for your installation.

• On UNIX operating systems, you must configure the environment before you run the Database Configuration Wizard. Run the script CreateDbSrvrEnvScript to generate the environment setup files dbenv.csh and dbenv.sh. Source one of these files before you run the Database Configuration Wizard. For more information, Installing the Siebel Database. See also General Requirements for Installing and Configuring Siebel Enterprise Server Components.

Requirements for AIX Only

The following requirements apply on HP-UX only:

• Before installing, verify that the login ID performing the installation has permission to run slibclean by asking the administrator to change the permission as follows:

  chmod 6555 /usr/sbin/slibclean

• Before you install Siebel Enterprise Server software on AIX, you must install X11 filesets, if they were not included as part of the base AIX installation.
• Java Runtime Environment (JRE) must be installed on any computer running AIX where you will run the installer for Siebel Enterprise Server or Siebel Web Server Extension software. In addition, the following requirements apply:
  • When you run the command for installing or uninstalling, specify the JRE installation location using the command-line option -jreLoc, as shown in Installing Siebel Enterprise Server.
  • Before you run the opatch command, which you use to verify the version of installed software, set the ORACLE_HOME environment variable. Then, when you run opatch, specify the JRE installation location using the command-line option -jre (instead of -jreLoc).

    For supported version information for JRE, see the Certifications tab on My Oracle Support.

Requirement for HP-UX Only

The following requirement applies on HP-UX only:

• If the environment variable LANG is set to a directory name that is a symbolic link, then the Java installer for Siebel Server will fail. You must reset any existing LANG variable to the directory that the symbolic link represents.

  NOTE:  The LANG variable cannot be set to univ.utf8. Doing so causes the installer to fail.

Requirement for Oracle Solaris Only

The following requirement applies on Oracle Solaris only:

• Set the TCP ndd variable tcp_co_min to the MTU of the network interface card.
