By any chance you have your redo logs on RAID05. Looking the wait timings I
strongly feel your I/O sub system is over loaded.
Pls let us know the hardware architecture. (Disk config, raid, etc). That
would help us understanding your problem better.

Hi
I checked my database and found
EVENT                               TOTAL_WAITS TIME_WAITED
----------------------------------- ----------- -----------
log buffer space                          12264     1094425
log file parallel write                  703116      227568
log file sequential read                 226133       65773
log file single write                       584        1298
log file switch completion                  940       77197
log file sync                            746881     8891791

log file sync value is increasing and waits are high.when i check all ratios
the ratios looks good.What could be problem?
Thx
