Introduction To <strong>SAP</strong> R/3 <strong>Basis</strong><br />
-----------------------------------------------------------<br />
R/3 Extended Memory<br />
User contexts are not only stored in roll files <strong>and</strong> the corresponding buffers.<br />
As of R/3 Release 3.0, they are primarily stored in R/3 extended memory.<br />
In R/3 extended memory, a large area of memory shared by all available<br />
work processes can be accessed through pointers. Using extended memory as<br />
well as roll files thus reduces the amount of copying from roll areas that is<br />
required during user context switches, <strong>and</strong> avoids the overhead caused by large<br />
roll-in or roll-out tasks.<br />
