NEED HELP!!!
Our 7.3.4 on AIX 4.3 with 2GB RAM. Most of jobs are batch jobs, concurrent
users are about 10.
I upgrade db_block_buffer to 1GB and shared_pool_size to 48MB. After
changes, I found there is
no improvement and one job even runs slower. I also found there are heavy
paging when jobs start.
Could anybody explain to me why that happened and Could I avoid paging by
resetting "minperm"
and "maxperm"(by through vmtune), e.g. minperm=10%, maxperm=40%, current
values are 20%
and 70%? Thanks in advance!!!
