Suggested use : when data changed frequently. Disadvantage  : can lead to deadlocks. <item-descriptor name="..." cache-mode="locked"> Locked caching is based on write locks and read locks.If no servers have a write lock for an item,any number of servers may have a read lock on that item.When a server requests a write lock,all other servers are instructed to release their read locks.Once an item is write locked,no other servers may get a read lock or write lock until the first server releases its write lock.In other words,once a server has a write lock on an item,all access to that item is blocked until the write is completed. A server requests a read lock the first time it tries to access an item.Once the server has a read lock on the item,it holds that read lock until the lock manager notifies the server to release its read lock.At that time ,it drops the item from its cache. A write lock is requested whenever a server calls getItemForUpdate...

Full Deployment Full deployment can be useful in the case when the assets on the target sites are modified manually or are corrupted. Target site might become inconsistent if a failure occurs during rollback,doing a full deployment,the previous set of assets created by different projects will become the  active assets of target site. Always gives the fresh latest version data to the target It can be time consuming as the all target data first purged then deployed again with previously deployed projects. It consumes number of resources on the target. Incremental Deployment It’s useful in the case when the assets which are deployed to the target are less in number after the first deployment. Whenever you have a need to rollback to the previous completed project then the incremental deployment is preferred to do because the full deployment will try to delete the all data from the target which can not be restored again. 1.   Faster than full deplo...

The missRatio indicates that the items in cache are not used or missed. That is your queries are returning totally different rows of data everytime and hence having a chance for them is useless. Look for a high missRatio and disable cache for these items. Same way if the missRatio is too low or the hitRatio is too high something like 90-95%, that means that we have almost all the data in the cache itself. This indicates that either our cache size is too big or the data in the table is not in large numbers. The usedRatio indicates the percent of the maximum cache size now in use. If this is too high, that means that most items in the cache are being used now. So we can increase the cache size. The usedRatio is the percent of  entryCount/cache size.  gives the number of entries currently in the cache. If this is same as your cache size consider increasing the cache size.
