Ray, please check this:
db2p105:~ # free -m
total used free shared buffers cached
Mem: 6025 4285 1739 0 16 4045
-/+ buffers/cache: 223 5801
Swap: 0 0 0
db2p105:~ # ps -eo pmem | awk '{pmem += $1}; END {print "pmem = "pmem"%"}';
pmem = 39.4%
With this, i can say, this machine needs +/- 2GB ?
this machine runs DB2... i'm a little confuse with this because system
requeriments for db2 ask a minimum of 3GB...
thanks for help!
