our issue with this post is "more space" is very generic and can mean several different things to several different people. i'm guessing that you are referring to address space??? again, i am not sure what you are looking for. what are the symptoms of your host(s)?

historical data is best seen through sar if you have set it up. there are other ways of getting host level data but again, there has to be a mechanism in place to capture data. if i were you, i would script something that captures several different outputs about your system every hour or so. you can obviously adjust this to what you see fit. process table, io stats, network stats, etc etc.

If what I understood is what you are clarifying - I would do the following

cron the following command to run every 10 minutes and save the output to a log file

0,10,20,30,40,50 * * * * * ps -u <ur username> -o pid,pcpu,pmem,command >> /tmp/mem_log

The above will log all your processes with cpu % and mem %. You can sort on the mem field and select the top 10 to see the top 10 mem hogging processes.

If you have certain processes spawing during the mentioned time, you need to write a script to check the utilisation of that PID using grep with prstat or sar.from there, you need to drill down to check the child process using ptree and see where the issue goes. If this is related to oracle, you can provide the pid to your DBA and they will know what to fine tune to the oracle parameters

Sorry but no one will succeed to help if you fail answering the questions asked.
What output are you expecting ? You just ignored that question of mine.
What is that "space" you are talking about ?
