Hi Manohar,
My first guess is memory is getting scarce and the server is faulting all the time. Three instances on a system (you don't specify how much physical memory you have) usually is something of a disaster. In all three systems issue a select * from v$sga, sum the numbers you get and you will know the total sga. Oracle recommends the SGA should take maximum one third of physical memory excluding NT.

The only way to know what your performance is, is running utlbstat and ultestat in the %RDBMS%/admin directory. Please consult Oracle documentation for details.

Hth,
Sybrand Bakker, Oracle DBA
