Editing a cache

You can see the number of objects in the cache, display cache statistics, or clear the cache.

Procedure

  1. Click Advanced > Cache.
  2. Edit the cache by clicking the Usage bar. These bars display the number of objects in each cache. To see the Rational® Focal Point™ number of objects and the percent of usage, hover the mouse pointer over each bar. The default value for each cache is set based on an average instance of Rational Focal Point. The typical percent of usage is 70 - 80% for each cache. If you need help to determine the number of cached objects, contact support.
  3. If you are using a clustered environment, you can specify that the number of cache objects be the same on each server by selecting Cluster Global.
    Important: If your servers have different hardware configurations, do not select Cluster Global.
  4. Display statistics about the cache by clicking Details.
    • Hit Count: The number of times that data was requested and retrieved from the cache
    • Misses: The number of times that data was requested and retrieved from the database
    • Hit Rate: The hit rate percentage. At startup, the hit rate is 0%. After requests are made, the increases to approximately 90%.
    • Number of Objects in the Cache: The current number of objects in the cache
    • Max Objects in Memory: The maximum number of objects in the cache
    Note: You can clear the cache by clicking Clear. The new data request is retrieved from the database; this request might take a long time.
