Home -> Community -> Mailing Lists -> Oracle-L -> RE: [Fwd: UNIX Performance Issues]
Rahul,
Did you get a response on this? I'm not sure I fully understand the actual question - are you looking for specific commands you need to run to get the information, or advice on how to interpret it? Don't forget that you will really need to correlate many of these statistics to the Oracle pathology at the same time. This then causes a problem because your sample points will at the very least experience clock drift and become harder to compare over time. There are ways to solve it, though. Anyway, if you could elaborate a little, I can try to assist! Regards
James

DBAs, This might be littlebit (or completely!) UNIX related... But I am told to do the performance analysis of some 10-15 machines and generate some statistical data to find out bottlenecks and identify areas of tuning... Operating System : Solaris 2.6 I have been using sar, iostat, top... I actually plan to script these things and run these scripts at certain intervals and put the data in database (Oracle 8i) and then do the crunching... Inputs are appreciated... 1. I/O What is current I/O status. Is there a lot of I/O going on? 2. Paging Is there lot of swapping / paging happening? Which processes are getting swapped in/out continuously? Are the I/O waits due to swapping / paging or regular stuff like DB waiting to read from DB files? 3. CPU What is the CPU utulization? Which processes are using lot of CPU? 4. Memory What is the current picture of Real and Virtual Memory? What processes are using how much memory? Which processes are i n real memory and which are in virtual memory? Which processes are swapped in and out from/to real/virtual memory and how many times? 5. Network What is the percentage utilization of network pipe? What is the capacity (bandwidth) of the network device? What percentage of that bandwidth is getting used? Is the system waiting for data from outside network I/O? In short, is there any bandwidth problem with network device or network traffic.
