If you want to continue running your older Cadence software while also letting some users run the newer software, follow these steps:
- Use Cadence installation software to install the new software in a different hierarchy.
- Stop the licensing daemons.
- Configure licensing (license file, clients file, rc.lic) for the new software with, licensing utilities, or with an editor.
- From the old hierarchy, create symbolic links to the new licensing files.
- The new license file lets the older software run, but you must use the newer license files and license daemons. To use both versions, link the old license files to the newer files.
- Occasionally, the name of a feature that a product uses changes, in which case you must copy the older feature to the new license file if it is not already there.
- Link your old license file to your new license file.
ln -s new_license_file old_license_file - Link your old clients file to your new clients file.
ln -s new_clients_file old_clients_file
- Make sure workstations can access the new license file.
- If the license daemons are already running, stop them.
- Start the license daemons.
- Users specify the hierarchy to use by setting their search paths to point to the correct install_dir/tools/bin.
Users should only have one Cadence hierarchy in their path at any given time.
C-shell users can set a shell variable to point to the desired installation
setenv CDS old_install_dir
and add the following line to their .cshrc files:
set path = ($CDS/tools/bin $path)
Source the file:
source ~/.cshrc
