reset buffer in SAP

[Former Member]

hi all

I've read that we can reset buffer in SAP using this command line /$SYNC

I've tried on our solman but it can not work

Is there anyway to reset the buffer without restarting server?

Thanks

Resetting buffers can significantly change the performance of the entire system for a long time. It should therefore only be used where there is a good reason to do so.

/$SYNC This resets all buffers of the application server

/$CUA This resets the CUA buffer of the application server

/$TAB This resets the TABLE buffers of the application server

/$NAM This resets the nametab buffer of the application server

Hi Jazz

on which path should I run that command?

reading your statement :

"Resetting buffers can significantly change the performance of the entire system for a long time. It should therefore only be used where there is a good reason to do so."

Is it different effects if I just restart our server? Because restarting our server also clearing the SAP buffer right?

You should run the command where you normally run the transaction.

Restarting the buffer also cleans up the buffers. Sometimes resetting the buffers may lead to skipping of number ranges in certain transactions. But its very rare. And when buffers are reset, some transactions may take more time for it to be executed as it has to fetch the data from database. (its the same case if you restart the server).

Hope its clear now.
