Siebel Installation Guide for UNIX: Servers, Mobile Web Clients, Tools > Preparing for Installation >

Selecting Your Media for Installation

You can install the Siebel eBusiness Applications using one of the following methods:

• Installing directly from the DVDs.
• Installing from a network image. You create a network image from the DVD files or using files downloaded from Siebel SupportWeb using FTP. See Creating a Network Image.

NOTE:  For system-wide installation in unattended mode, you must create a network image.

Downloading the Files Using FTP

You can download the files required for installation from SupportWeb. After you have downloaded the files, you can validate the integrity of the files using the Cyclic Redundancy Checksum (CRC) utility. For more information on this utility, see Validating the Integrity of Files.

Compressed media (TAR files) should be downloaded to a central network location.

NOTE:  When you untar TAR files, the base files must be uncompressed before the language files to preserve the integrity of the CRC files.

Validating the Integrity of Files

If you download a Siebel distribution from SupportWeb or copy it to a hard disk from the distribution DVD, you may want to verify that the distribution was copied correctly and that no files were lost or corrupted. Siebel Systems provides the Cyclic Redundancy Checksum (CRC) utility, a command-line utility, for this purpose.

The utility computes checksums on the copied files and compares them to the checksums of the distribution files. The checksums for the distribution files are contained in a signature file, crc.txt, which is also included in the distribution. The utility verifies that no files were lost or corrupted.

When you run the Siebel installation program from the distribution DVD, you do not need to validate the integrity of the files it installs on your system.

Prerequisites

• You must have the required version of the Java Runtime Environment (JRE) installed. For information on the JRE requirements and supported version, see System Requirements and Supported Platforms on Siebel SupportWeb and see Siebel System Administration Guide.
• The system file path must include the JRE.

To validate downloaded files

1. On the system where you have downloaded or copied the distribution files, open a command-line window.
2. In the command-line window, navigate to the UNIX_OS/Server/Siebel_Enterprise_Server directory.

   where:

   UNIX_OS = Your UNIX operating system, such as AIX, Solaris, or HPUX (for HP-UX)

3. Run the following command to validate all the files in the distribution:

   java -jar cksum.jar -validate -r crc.txt > log.txt

   where:

   log.txt = The name of the output file and the location (if you want to save it in a different directory)

   This command validates the files (except siebel.ini) and logs the output to the file log.txt.

4. To view the help file for the cksum utility, run the following command:

   java -jar cksum.jar -h

5. Use a text editor to open and review log.txt.
   • If the copied files match the distribution files, the log file reports Validation Successful.
   • If the copied files do not match the distribution files, the log file reports an error.
6. If the log file reports that the validation was not successful, download or copy the distribution again.
7. Navigate to directories representing additional installable modules, then repeat Step 3 through Step 6 for each module.
