Hi

Kumar

In which transaction or file u are saying semaphores are high

is the disk utilization high, how much free space available in the tablespaces.

Hope for further check here

ST02 (tune summary)

--> Detail analysis

[additional functions]

--> Semaphores

If this is the first time going there, then be sure to read the legend carefully:

first line = "Wait time entering the critical path"

second = "Residence period in the critical path"

I never came across such high semaphores

Regards

Bhaskar
