Hi everybody!
I have a big application running on premise. One of my main database servers has the following configuration:
72 CPUs(2 chips, 18 physical cores per chip, 2 threads) Xeon Gold 6240
1TB of ram or 786GB (5 servers at all)
A huge storage( I don't know for sure what kind is, but is very powerful)
A consulting company recommended the following configuration for theses main servers(let me know if something important was left behind):
maxx_connections = 2000
shared_buffers = 32GB
temp_buffers = 1024
max_prepared_transactions = 3000
work_men = 32MB
effective_io_concurrency = 200
max_worker_processes = 24
checkpoint_timeout = 15min
max_wal_size = 64GB
min_wall_size = 2GB
effective_cache_size = 96GB
(...)
I Think this is too low memory setting for de size of server... The number of connections, I'm still measuring to reduce this value( I think it's too high for the needs of application, but untill hit a value too high to justfy any memory issue, I think is not a problem)
My current problem:
under heavyload, i'm getting "connection closed" on the application level(java-jdbc, jboss ds)
