Initial memory allocation on ODA X-32

Hi All,

We have installed ODA X-32 with the default configuration as "Stand-alone Installation". and after that we have created 4 databases with following templates

Large - 1

Medium - 1

Very Small - 2

after that when I executed Linux free command to chek the avaialable memory, result is as below:

             total              used             free                  shared    buffers     cached
Mem:     264410104  202570556   61839548          0            835620      52851632

As per my opinion that so far we only have created 4 databases with the above selected tamplates and it should not use more than 75GB while it is showing way more than expected.

Can anybody put some light if there are some other services installed by default and how can we check and disable them if not needed.
