Memory: Correlate prstat with NDB Config values
I need to upgrade the memory of my Solaris MySQL Cluster. I know my NDB Nodes are running low on memory but I can't seem to get a good correlation between `prstat -s rss` and the values in my management server's config.ini file.
The config.ini shows:
SendBufferMemory=4M
ReceiveBufferMemory=4M
DataMemory=5004M
IndexMemory=883M
SharedGlobalMemory=1024M
# DiskPageBufferMemory=2048M
StringMemory=25
TransactionBufferMemory=8M
And when I go on one of my nodes (All 6 report the same total memory of 7781) and run `prstat -s rss` I see the following:
PID USERNAME SIZE RSS STATE PRI NICE TIME CPU PROCESS/NLWP
76717 root 7781M 7575M sleep 6 0 785:06:54 1.5% ndbd/40
When I add up the memory in the config file I get 6952M. Why do I not get 7781M?
Can someone please help me find the most accurate correlation of memory between prstat and the config file?
Thanks in advance
