[las_users] Questions on cleaning & maintaining the cache manually



We have not installed/setup the user interface the web maintenance, and have a few questions on how the productserver.xml, the cache.obj, and the /usr/local/tomcat/webapps/las/output/ directory interact with each other, and how we can manage the cache.  Recently our disk was filled by files in /output/ , and we are looking to understand the processes and avoid disk-fill in the future.


Our productserver.xml has this setup:

<cache size="1500" bytes="1024Mb" file="/usr/local/tomcat/webapps/las/output/cache.obj"/>


Productserver.xml  interactions:

1)       Does the cache size = 1500 refer to the number of lines in the cache.obj file, or the number of files currently in the /webapps/las/output/ directory?


2)      The files in the /output/ directory that start with the same ID - for example,






-- Are these files considered one file by the cache size, or four files? 


3)    Does the bytes=1024Mb indicates the files size of cache.obj or the total size of the directory /usr/local/tomcat/webapps/las/output/ ?


Manual Cache clearing:

4)       Can we clean the cache by doing:

Stop Tomcat

Delete all files in /usr/local/tomcat/webapps/las/output/    (Or all but cache.obj?)

Restart Tomcat


Automatic purge settings:

5)      How can we check/confirm the number of files listed in cache.obj?  It's difficult to read/parse the file. 


6)      Currently our file count in /usr/local/tomcat/webapps/las/output directory is: 10,735, way above file size=1500.  We thought that cache.obj would purge older files, bringing it down to below 75% of 1500?  Or is cache.obj only counting the ID’s, not the individual files?  (as in question 2 --  We are not sure if the current cache.obj has in its list 10,735 files, due to having difficulty parsing it.)



Thanks very much,
