PostgreSQL Max connections

Avatar
Sam path

Hi All,

I have installed a bitnami Odoo in Amazon EC2 m4.10xlarge  instance which has 40 vCPU, 160GB RAM and 500GB hard disk

By default PostgreSQL has a max_connections of 150 and I would need it to be increased to 100000(1Lakh connections)

May I know what changes do I have to do in postgresql.conf and sysctl.conf?

Thanks,

Sampath

You need to increase the max_connections settings in postgresql.conf according to this guide:

https://wiki.postgresql.org/wiki/Tuning_Your_PostgreSQL_Server

Normally you need to change: max_connections, shared_buffers and work_mem settings

but read it carefully for your environment, also I suggest you to use a connection pooling like pgbouncer according to this guide

https://wiki.postgresql.org/wiki/Number_Of_Database_Connections

Use the connection pooling to reach your number of max_connections instead of config postgresql to that insane value, read more about that here: http://www.cybertec.at/2014/03/max_connections-performance-impacts/

This are just a few tips, hope this helps
