# Enabled indicates whether the oracle is enabled.

# Oracle Address is the URL of the out of process oracle sidecar. This is used to
# connect to the oracle sidecar when the application boots up. Note that the address
# can be modified at any point, but will only take effect after the application is
# restarted. This can be the address of an oracle container running on the same
# machine or a remote machine.

# Client Timeout is the time that the client is willing to wait for responses from

# MetricsEnabled determines whether oracle metrics are enabled. Specifically

# the oracle and the app.

Change systemd

sudo nano /etc/systemd/system/slinky.service

ExecStart=$(which slinky) --oracle-config-path $HOME/slinky/config/core/oracle.json --market-map-endpoint 0.0.0.0:<port grpc>

Reload systemd

sudo systemctl daemon-reload 
sudo systemctl restart slinky.service

Check the systemd log
