Hi,
I´m trying to tune a linux box with a 12 GB database and 4 GB RAM. First of all I would like to stop the swapping, so the shared_buffers and sort_mem were decreased but even so it started swapping two hours after DBMS started up.
I would like to know some suggestions how to discover why is it swapping?
I´ve collected the following data from the environment and saved at http://paginas.terra.com.br/educacao/rei/dados.htm
1. select version()
2. uname -a
3. cat /proc/cpuinfo
4. cat /proc/meminfo
5. vmstat 5
6. pg_stat_activity
7. postgresql.conf
Thanks in advance!
Reimer
