Thread: Clearing Memory Buffer in Linux

I have oracle database and I want to clear memory after particular period so tell me which command is utilized to clear buffer memory in Linux. I want script which has code and can run automatically when buffer size reached max. Any help will be appreciated.

Linux gives memory management characteristics with cache memory feature. If there is extra space in RAM and getting slow processing in start of database. Then it happens, you would not organize cache memory and cache being stored on RAM and startup files are loaded on RAM.

If RAM failed to run processes at appropriate time. You can clear filled memory buffers by following command :
sync; echo 3 > /proc/sys/vm/drop_caches

To clear memory buffer use crontab utility with time interval. Here shown how to set time interval of running command permanently.

Code:

15 14 1 * * echo 3 > /proc/sys/vm/drop_caches

This statement in crontab file Run at 2:15pm on first of each month means related command run mechanically to clear buffer at particular time.
