Hello All,
I'm working on large web application which has got number of configuration parameters, i.e NO_OF_PRODUCTS_ON_SEARCH_SCREEN = 5.
Currently this parameters are in one Parameters.java file(statically loaded) and all action/ejb/jsp uses this .java file for usage.
if(Parameters.NO_OF_PRODUCTS_ON_SEARCH_SCREEN > 5){ //do something..}
else{ //do something else....}
Now ,as parameters do change frequently on client request, I have added all those to parameters to DB with creating proper schema. Lots of action/jsp/ejb uses this parameters(Let's say one web request uses 10 parameters) and If every time I make a DB request to lookup parameter it kills my performance so I have introduced caching between action/ejb/jsp and DB.I have used EHCache here and on lookup from acton/ejb/jsp goes to cache and cache result is returned if it's cached otherwise explicit DB request is made.
My application is in clustered environment and has got more than one server so I will have either go with 'cache replication' or 'share a cache'
Question 1 : If I am going to share cache , Is Symbolic link good solution?
Question 2 : What are the possible caching solution which has got this capability of replication in clustered environment. So far , I have explored EHcache , JCS and JBoss cache but need some more views (which is better,stable , faster for replication) to gain good performance in web-application.
Any views for above scenario or answers for questions would be great help.
