The advantage of core tiles is that they allow you an opportunity to examine the cause of problems, so that they
can be resolved.
However, core files must be managed because they_____.
A.
take up large amounts of disk space
B.
make numerous entries into the /var/adm/wtmpx file
C.
steal resources from the processor, slowing down system performance
D.
fill up swap space; this will begin to slow the system due to swaps
E.
fill up swap space; this will begin to slow the system due to paging
Explanation:
Part of the job of cleaning up heavily loaded file systems involves locating and removing files that have not
been used recently. You can locate unused files by using the ls or find commands.
Other ways to conserve disk space include emptying temporary directories such as the directories located in /
var/tmp or /var/spool, and deleting core and crash dump files.
Note: Core files are generated when a process or application terminates abnormally. Core files are managed
with the coreadm command.
For example, you can use the coreadm command to configure a system so that all process core files are
placed in a single system directory. This means it is easier to track problems by examining the core files in a
specific directory whenever a process or daemon terminates abnormally.
