Hello all,
We are planning to test one of our products,
which works with Oracle, on PostgreSQL. The database size is about
100 GB. It is a product with a not-so-high load ( about 10 tps - mostly
read). My doubts are about PostgreSQL settings. For Oracle, we give about
4 GB SGA (shared buffer) and 1.5 GB PGA (sum of session-specific memory).
The machine configuration is
Opteron 2CPU * 4cores @ 2.3GHz
16GB RAM
OS Solaris10 x64
So far I have changed the following
settings in postgresql.conf
shared_buffers = 2GB
temp_buffers = 8MB
work_mem = 16MB
maintenance_work_mem = 32MB
wal_level = archive
checkpoint_segments = 10
checkpoint_completion_target = 0.7
archive_mode = on
effective_cache_size = 6GB
log_destination = 'csvlog'
logging_collector = on
log_directory = '/backup/datapump/pgdata/log'
log_filename = 'postgresql-%Y-%m-%d_%H%M%S.log'
log_rotation_age = 1d
client_min_messages = notice
log_min_messages = warning
log_min_duration_statement = 3000
Could you please let me know the parameters
I should pay attention to? Do the settings mentioned above look OK?
We are suing weblogic. Should we let
weblogic manage the connection pool or try something else?
Regards,
Jayadevan
