Configure the minimum number of transactions a user needs before becoming a mentor

The following setting specifies the minimum number of transactions a user must have before becoming a mentor. The sifter uses this setting if the Clickstream Engine is using that mentor set.

Procedure

1. To configure the minimum number of transactions required as a percentage of the total number of items in the database:

   1. Stop the LikeMinds server inside the WebSphere Application Server.

   2. Use any database modification tool to enter the following SQL statement:

      update lps_cfg set value='3%' where
      name='xactionMentor.min_mentor_xactions'
      

   3. Start the LikeMinds server inside the WebSphere Application Server.

2. To configure the minimum number of transactions required as an absolute value (that is, without a percentage):

   1. Stop the LikeMinds server inside the WebSphere Application Server.

   2. Use any database modification tool to enter the following SQL statement:

      update lps_cfg set value='3' where
      name='xactionMentor.min_mentor_xactions'
      

   3. Start the LikeMinds server inside the WebSphere Application Server.

   Use the following guidelines for setting mentor_set_name.min_mentor_ratings:
