Where are user credentials stored?

User credentials are stored in the 'boot.properties' file , which has its encryption key in the 'SerializedSystemIni.dat'

If you use a script to start a server instance, it is recommended that you do not use this technique because it requires you to store an unencrypted password in the startup script.
Suggest few JVM tuning parameters.

Initial heap size and maximum heap size to be same (-xms and –xmx):T his  ensures less is spend by the CPU to allocate memory in rutime

Young generation (-XX:MaxNewSize): The bigger the young generation, the less often minor collections occur. However, for a bounded heap size a larger young generation implies a smaller tenured generation, which will increase the frequency of major collections. The optimal choice depends on the lifetime distribution of the objects allocated by the application.
