Managing Memory

The system performs most memory management tasks automatically. The system
allocates some memory permanently and some memory temporarily. When
applications are deleted, memory that the system assigned temporarily becomes
available again.
The system releases available memory on an SRP module or line module automatically
if that module requires extra memory for an application. However, you can force
the system to release available memory on the primary SRP module if you issue
either the show processes memory command or the show utilization command.
For information about the show processes memory command, see "Managing Files"
on page 290. For information about the show utilization command, see "Managing
Modules" on page 355.
NOTE: When you issue the show utilization command, the system releases available
memory on the SRP module immediately; however, the display appears a few seconds
later.

Managing Files

You are responsible for file management. Table 33 on page 290 shows the types of
system files and their corresponding extensions.
