RE: Max_connections limit

Hi,

 

If you reckon the application initiates such a large number of concurrent connections, I’d suggest you configure a connection pooler to avoid the connection overhead by PostgreSQL. max_connections will be the parameter you are looking at to configure but ensure it is configured in conjunction with a connection pooler.

Subject: Max_connections limit

 

Hello team,

 

We have migrated our database  from Oracle 12c to Postgres 11. I need your suggestions , we have sessions limit in Oracle = 3024 . Do we need to set the same connection limit in Postgres as well. How we can decide the max_connections limit for postgres. Are there any differences in managing connections in Oracle and postgres.

 

SQL> show parameter sessions;

 

NAME                                 TYPE        VALUE

------------------------------------ ----------- ------------------------------

java_max_sessionspace_size           integer     0

java_soft_sessionspace_limit         integer     0

license_max_sessions                 integer     0

license_sessions_warning             integer     0

sessions                             integer     3024

shared_server_sessions               integer

SQL>

 

Regards,

Daulat
