1. Select Manage discovery methods from the Tools menu, as shown in the following screenshot:
   
2. Right-click on an existing User or WhereScape defined discovery method and choose Copy, as shown in the following screenshot:
   
   Alternatively, to create a new discovery method from scratch right-click on 'User' in the discovery method manager tree and select 'New vendor version'.
   
   
   The Copy vendor version dialog is displayed, as shown in the following screenshot:
   
3. Change the Name, Vendor, Min version and Max version as required and click OK.

   An asterix * can be used as a wildcard for either the whole version number or the minor version number in both the Min version and max version. For example , 9., and 9.0 are all valid values for Min version and Max version and match any version, any version 9 release, or only version 9.0 respectively. The method will be allowed to be used for any version between Min version and Max version (inclusive).

   An asterix * can be used as a wildcard for either the whole version number or the minor version number in both the Min version and max version. For example , 9., and 9.0 are all valid values for Min version and Max version and match any version, any version 9 release, or only version 9.0 respectively. The method will be allowed to be used for any version between Min version and Max version (inclusive). Any User Defined Discovery methods created with a version of 3D prior to 2.4.0.0 match on the Version string returned by the RDBMS server. Leaving the version as * will allow the method to be used for any version.   You need to assign the new discovery method to a model version for it to be used.

4. The user defined methods can be edited as required—see details below.
