The default sizes of the rollback segments and redo logs are very small. Do you have all these tablespaces on single disk. Use system tools like iostat etc. and locate which is causing the excessive IO. Also you can use oracle tracing and tkprof tool to estimate the statistics of the database operations. This will give you the details of CPU time, disk usage, indexing issues if any

NAME
mysql_zap - kill processes that match a pattern SYNOPSIS
mysql_zap [-signal] [-?Ift] pattern DESCRIPTION
mysql_zap kills processes that match a pattern. It uses the ps command and Unix signals, so it runs on Unix and Unix-like systems. Invoke mysql_zap like this: shell> mysql_zap [-signal] [-?Ift] pattern A process matches if its output line from the ps command contains the pattern. By default, mysql_zap asks for confirmation for each process. Respond y to kill the process, or q to exit mysql_zap. For any other response, mysql_zap does not attempt to kill the process. If the -signal option is given, it specifies the name or number of the signal to send to each process. Otherwise, mysql_zap tries first with TERM (signal 15) and then with KILL (signal 9). mysql_zap supports the following additional options: o --help, -?, -I Display a help message and exit. o -f Force mode. mysql_zap attempts to kill each process without confirmation. o -t Test mode. Display information about each process but do not kill it. COPYRIGHT
