lost objects
-------------
Key: JCS-51
URL: https://issues.apache.org/jira/browse/JCS-51
Project: JCS
Issue Type: Question
Components: Indexed Disk Cache
Affects Versions: jcs-1.3
Environment: java 6 , windows xp
Reporter: Manfred Quasten
Assignee: Aaron Smuts
Priority: Blocker
Fix For: jcs-1.3
We will use JCS to create a large number of (large) objects on disk with a smal
javaheap size. So I set MaxPurgatorySize=100 and wrote 100000 objects to the
cache
id is the counter of the for loop as String.
jcs.putInGroup(id,"aGroup",object);
After this, I tried to read this objects, in an other loop
final int x = (int) (100000*Math.random());
jcs.getFromGroup( "" + x , "aGroup").
get FromGroup will return null in 50% of the cases. What is going wrong?!
I get the cache using
jcs = JCS.getInstance("myRegion1");
I can't increase MaxPurgatorySize=100, because we will work (test working) with
a minimum of java heapsize.
Here is my configuration:
