Fix Recommendation

Note: The following instructions use the PGDATA and PGVER environment variables. Refer to APPENDIX-F for instructions on configuring PGDATA and APPENDIX-H for PGVER.

As the database administrator (shown here as "postgres"), edit postgresql.conf:

$ sudo su - postgres
$ vi $PGDATA/postgresql.conf

Set the following parameters to organizational requirements:

statement_timeout = 10000 #milliseconds
tcp_keepalives_idle = 10 # seconds
tcp_keepalives_interval = 10 # seconds
tcp_keepalives_count = 10

As the system administrator, restart the server with the new configuration:

$ sudo systemctl restart postgresql-${PGVER?}

Check Contents

As the database administrator (shown here as "postgres"), run the following SQL:

$ sudo su - postgres
$ psql -h localhost -c "SHOW tcp_keepalives_idle"
$ psql -h localhost -c "SHOW tcp_keepalives_interval"
$ psql -h localhost -c "SHOW tcp_keepalives_count"
$ psql -h localhost -c "SHOW statement_timeout"

If these settings are not set to something other than zero, this is a finding.
