Prerequisites to install on Citrix software

Before you install Rational® DOORS® on Citrix software, make sure that you meet the installation prerequisites. In addition, be aware of what to do to ensure the best performance of the software.

Installation prerequisites

Before you install Rational DOORS on Citrix software, make sure that you meet these prerequisites:
  • Use floating licenses.
  • Activate terminal services on the host computer.
    Tip: When you install Citrix software, rename the drives; for example, change the drives from A, C, and D to M, N, and O. When you change the drives, the Citrix clients can redirect their local drives to the A, C, and D drives.
  • Increase the swap file to 2.5 times the amount of memory that is available.
  • Increase the registry file size appropriately to accommodate the multiple current_user_keys that are required.
  • Make sure that you are in Install mode.
  • Configure Rational DOORS to be displayed in Seamless mode. If you use Desktop mode, problems might occur.
  • Use 16-bit color depth resolution in the Citrix ICA client. The Rational DOORS client displays colors correctly for highlighted text only when you use the 16-bit color depth resolution in the Citrix ICA client.

Performance

For the best performance, install the Rational DOORS database server on a different computer than the Citrix server. To optimize performance, place both computers as physically close to each other as possible, for example in the same room. The Rational DOORS license server can be on either computer or on a separate computer. For information about Rational DOORS integrations and the Citrix environment, see the documentation for the integrated product.
