Configure the mentor pool size
The priority list size dictates how many users to sift during a single batch. By default, the value is 10.
To configure the maximum number of mentors that can be in the pool:
Procedure
- Stop the LikeMinds server inside the WebSphere Application Server.
- Use any database modification tool to connect to the database, and to enter the following SQL statement:
update lps_cfg set value= '5000' where name = 'xactionMentor.mentor_pool.size'
- Start the LikeMinds server inside the WebSphere Application Server.
Results
Use the following guidelines for setting mentor_set_name.mentor_pool.size:
Total Number of Items in Database Suggested Setting < 1000 <= 500 1000-5000 <=1000 5000-10,000 <= 5000 10,000+ <= 5000
The bigger the mentor pool size, the more likely it is that the mentors chosen for recommendations will have been selected for their coverage contribution, and not their similarity contribution. In order to allow the LikeMinds server to select the most reliable mentors and hence return the most accurate recommendations, carefully balance the size of the mentor pool with the maximum number of mentors configured for the system.
