Updating an Existing Hierarchy

In a given installation directory, you can install software only from a single release. InstallScape does not let you install products from different releases in the same hierarchy.

You can update a hierarchy using a Baseline DVD or an Update or Hot Fix DVD. You can update a hierarchy with a DVD set that has the same release identifier as the release identifier of the release installed in the hierarchy.

Protect Your Production Environment

To protect your production environment during the installation process,

• Do not install your software in a directory that is your current production hierarchy. Install your software in a new hierarchy or a copy of your production hierarchy.

• Do not install software from more than one baseline release into the same hierarchy.

• Test the installation fully before making it your production hierarchy.

Updating the Existing Hierarchy

To install the release into an existing hierarchy,

1. Log in to the proper account.

2. Create a duplicate hierarchy from the original Baseline DVD using the same method you used to install the production hierarchy.

   Alternatively, you can create a duplicate of the Cadence hierarchy you want to update by using operating system commands, such as the UNIX tar command.

   Do not use the cp command because it does not preserve file system links.

3. Identify the DVD to use first.

   If you have received only a set of Baseline DVDs, use the Baseline DVD#1 first.

   If you have received only a set of Update or Hot Fix DVDs (and the Installation Control e-mail file), use the Update or Hot Fix DVD#1 first.

   Note:  You will need the corresponding Baseline DVD set to complete the installation.

   If you have received both a set of Baseline and Update or Hot Fix DVDs (and the Installation Control e-mail file), use the Update or Hot Fix DVD#1 first.

   Note:  The type of DVD you mount first (Baseline, Update, or Hot Fix DVD#1) determines the resulting installation type. That is, if you start with Baseline DVD#1, you will install the baseline version of the selected products. If you start with an Hot Fix DVD#1, you will install the Hot Fix version of the products as they existed on the date that the Hot Fix DVD set was created.

4. Mount the DVD.

   Note:  The installation starts automatically when you insert the DVD on a Microsoft Windows system.

   1. Log in as root.

      Note:  You do not normally need root permission to mount a DVD on Solaris.

   2. If it does not already exist, create the DVD directory by typing

      mkdir /dvd_dir

   3. Insert the DVD into the DVD drive.

   4. Mount the DVD drive on the DVD directory, using the appropriate command:

      


      Solaris	/etc/mount -F hsfs -o ro /dev/< device> / dvd_dir Note:  Normally, the Solaris OS automounts the DVD. In case the automount fails, see Solaris does not mount the DVD automatically for troubleshooting tips.
      HP-UX	/etc/mount -F cdfs -o ro /dev/dsk/< device> / dvd_dir Note:  Typically, the device name to represent DVD in HP-UX is c0t0d0.
      AIX	/etc/mount -v cdrfs -o ro /dev/< device> / dvd_dir Note:  Typically, the device name to represent DVD in HP-UX is dvd0.
      Linux	/bin/mount -o ro /dev/ <device> / dvd_dir Note:  Typically, the device name to represent DVD in Linux is dvd.

   5. Log out as root.

5. Start the interactive setup utility.

   On a UNIX or Linux system, type

   dvd_mount_point/SETUP.SH

   On a Microsoft Windows system, the installation should start automatically. If it does not, go to the top-level directory of the DVD and run the setup.exe program.

6. When SETUP.SH asks you to specify the path to your_install_dir , type the path to an existing Cadence installation directory (this could be the duplicate hierarchy you created previously).

7. Answer the prompts, and proceed as directed.

   The appropriate installation utilities, InstallScape or InstallShield, should start automatically. If it does not start, do one of the following:

   • On UNIX, type

     ./iscape/bin/iscape.sh&

     
     

   • On Windows, double-click on setup.exe at the top level of the DVD.

8. Do one of the following:

   • Load the Products and Licensing Using InstallShield.

     InstallShield is a GUI-based installation wizard. Each screen includes instructions.

     InstallShield allows you to install the license manager, install products, and update your license file.

     The installation is customized for each product family: see the README file at the top level of your DVD for appropriate information.

   • Load the Products Using InstallScape.

     If InstallScape has not started, type

     ./iscape/bin/iscape.sh&

     
See the InstallScape User Guide for more details on how to use InstallScape for installing Cadence products.

Creating the Tools Link (if required)

Some Cadence tools require a tools directory to be present in the installation hierarchy. This tools directory should be a symbolic link to the tools .<platform> directory that is created at the time of installation. Typically, this link is created automatically when you run product configuration scripts such as licensing configuration.

If this link does not exist, do the following:

1. Change to the installation directory by specifying the following command at the command prompt:

   


   cd <install_dir>

2. Create the tools link by specifying the following command at the command prompt:

   


   ln -s tools.<platform> tools
