Sometimes situation arise when we try to start our db and we get error like not sufficient memory available, so unable to start our database. so one other option that we have is if there are no other DB on the host machine and if it is a Linux OS, then you can use the below command to clear the RAM without restarting the server machine –
“sync; echo 1 > /proc/sys/vm/drop_caches”
The above command can be used in Production servers to clear RAM without restarting the macine.

(Please be Really careful while trying other options)
