Pool Utilization ...
Hello all
I allocated 110M, 125M and 116M respectively to Java_pool_size, Large_pool_size and Shared_pool_size...
How do we know whether what is the utilization of space we allocated to these parameters ....are tehse parameters utilizing all the space or only 20% or what ?
Is there any sql command or something like that from which we will know ?
Thanks
Ron

v$sgastat
but it seems to me you are allocating space for pools which you dont need them, obviously I am assumming but do you use many java stored procedures and MTS? (Considering MTS here only since RMAN/PQ/process slaves dont use that much space in large pool)
