Solaris server performance
Posted on 2013-05-16
i have a problem with my Solaris server. we have created one Solaris Zone on the server and two of database are running on the zone.
now the problem is, our customers are complain that database is running very slow and it is unresponsive. when i logged in to the server and try to run some OS commands like, vmstat, top, iostat ... etc. and these commands are almost hung i will get reply after 15 -20 min.
at the same time, i did see IO wait from the database awr reports.
i suspect some issue with OS level. how to pin point the problem. i don't see any messages/useful information from /var/adm/messages as well as syslogs.
please advice how to troubleshoot this problem.
