Native Process Environment
When a process is created, it occupies space in virtual memory. The basic
organization of a process is discussed next in terms of code spaces, which are
associated with the objects in the preceding list, and data spaces.
Code Segments
A process has distinct code segments that contain executable code. (Segments is the
term used for TNS/R and TNS/E native processes. In the TNS environment, the term
code spaces is used.) This table compares the code segments for TNS and TNS/E
processes:
Process Type Code Segments
TNS process on TNS/R
