Edit sqlnet.ora to add a 64 character crypto-seed

The MIT Data Warehouse requires an encrypted connection between your computer and the Data Warehouse. This is configured by a series of parameters included in the sqlnet.ora file. For security reasons, the SQLNET.CRYPTO_SEED should be unique for each computer accessing the Data Warehouse. Follow the instructions detailed below to create a unique crypto seed for your sqlnet.ora file.

  1. Right-click on sqlnet.ora and choose Open with...
    • If Open with... is not available, choose Open, then choose Select a program from a list of installed programs and press OK.
  2. Browse the list of applications and choose.
  3. Choose Notepad and click OK.
  4. Locate the entry:
    SQLNET.CRYPTO_SEED = "replace the text between these quotes with exactly 64 characters, using a upper and lower case letters, numbers and special characters"
  5. Replace the text between the quotes with exactly 64 characters, using upper and lower case letters, numbers and special characters. Leave the quotation marks in place.
  6. Follow the menu path File >> Save.
  7. Close the file.

Move the files into Oracle's network\admin directory

  1. Right-click on ldap.ora and choose Copy.
  2. If there is a chance that there is more than one Oracle installation on the machine, you'll need to look in the Path variable to ascertain which Oracle installation appears first in the Path. This is the Oracle installation which will need the MIT configuration files.
    • To find the Path variable, go to Start > Control Panel > System > Advanced > Environment Variables
    • Look for Path.
    • Copy and paste the path into a text editor such as Notepad. Look for the first time that Oracle appears. The entry will be for the Oracle bin directory.
  3. Navigate, on your hard drive, to the Oracle installation. If there is more than one Oracle installation, be sure to choose the one that appeared first in the Windows Path variable (see Step 1).
  4. Within the Oracle directory structure, navigate to c:\oracle\product\11.2.0\client\network\admin.
  5. Copy ldap.ora and sqlnet.ora to this location.
  6. When prompted, choose Copy and Replace, to replace the generic Oracle sqlnet.ora file.
