Re: How I know How many memory get Oracle and Unix
The first thing I'd do is add more RAM to the machine though.
1GB on an rp (which rp? - 24xx, 54xx, 74xx?) running Oracle is not much. I would increase it to at least 4GB.

Re: How I know How many memory get Oracle and Unix
I think the best to do is assign points to all those people who helped you before. (you never did to anybody)
After that I have some scripts for you that might help.

Re: How I know How many memory get Oracle and Unix
The ipcs command will provide some maximums but by itself, won't provide all the info desired. Without Glance, it will be a manual procedure that will only provide a general approximation - and even Glance data will not be 100% accurate - several numbers reported by Glance are estimates and not actual counts (cost too high for accurate accounting). If you don't have access to the Glance trial bits then you'll need info from ps -elf (at least the SZ column), ipcs output, some sar data and probably vmstat. The data points will then need to be manually coalesced for any meaningful interpretation.

Re: How I know How many memory get Oracle and Unix
vmstat
The output from vmstat will show the number of page-outs that occur (the po column) and if this number is more than 10 to 20 (repeat the command several times during the busiest times), then your system is swapping pages out of memory and slowing everything.
You can collect all the data from various system components such as the buffer cache, shared memory, shared libraries, memory mapped files, processes, kernel structures, etc but it is quite complicated. Suffice it to say that knowing this level of detail will not help as 1Gb is just too small for Oracle products.

Re: How I know How many memory get Oracle and Unix
Why I put the point assigment and press "submit" but I can't see the points assigned?
