Re: What does mean by SWAP? Where should we monitor this? what is the threshold value for swaps/day? If it is more what will u do?Answer# 2

the accessed data will sit in the buffer. If someone is trying to access the same data, that will be retrieved fast from the buffer. If the buffer is full and some one is retrieving the data which is not there in the buffer then that data will be fetched from DB and placed in the buffer and the oldest data in the buffer will be swapped for this. More number of swaps means more DB hits. If there are more Swaps we can increase the buffer size

 Re: after changing some parameters in rz10 and restart, the system doesn't start up?what to do?Answer# 2

When you make changes in RZ10 and save it, before overwriting the profile files in /sapmnt/<SID>/profile folder the system makes a file with extention .BAK which is created just before overwriting the original file.So incase if you system doesnt comes up after making changes in RZ10. Just backup the current profile files and then rename the .BAK with the original file name which will bring back the old profile status, then try starting the SAP system.As a best practice you should always back the profile files before making any changes to it.
