Q.difference between synchronize and full synchroniz????


Synchronization is a process of replicating the Config directory from Dmgr to other apps server Node's,

Normal sync will do replication of the updated files alone
For example ,If you have created a Datasource in the console and when you do sync,The resource.xml file alone from Dmgr CELL directory will be synced with the other Node's CELL directory

if the same scenario in Full-sync, The complete CELL directory will be overwrited from Dmgr to other Node's config directory

So the normal sync will sync the updated files alone ,

The full-sync will sync the compleat CELL directory from DMGR to Node's
