Introduction To <strong>SAP</strong> R/3 <strong>Basis</strong><br />
-----------------------------------------------------------<br />
R/3 Memory Areas<br />
Users need two kinds of memory:<br />
R/3 buffers<br />
Memory accessible to all users, for:<br />
Programs<br />
Table <strong>and</strong> field definitions<br />
Customizing tables<br />
User context<br />
Memory attached to individual users, for:<br />
Variables, lists, internal tables<br />
Administrative data (such as authorizations)<br />
Physical <strong>and</strong> Virtual Memory<br />
<br />
Unlike physical memory, virtual memory can be allocated. The operating<br />
system determines if the allocated memory area resides in the physical memory<br />
or in the operating system swap space.<br />
Depending on the operation system, the maximum size of the virtual<br />
memory may vary between the size of the operating system swap space <strong>and</strong> the<br />
sum of physical memory <strong>and</strong> operating system swap space.<br />
