Red Hat Summit8.2.2. Database connection arguments
Optional connection arguments are configured by the DB_CONNECTION_ARGS parameter. Some of the key-value pairs defined under DB_CONNECTION_ARGS are generic, while others are database specific.
| Field | Type | Description |
|---|---|---|
| DB_CONNECTION_ARGS | Object | Optional connection arguments for the database, such as timeouts and SSL/TLS. |
| .autorollback | Boolean |
Whether to use thread-local connections. |
| .threadlocals | Boolean |
Whether to use auto-rollback connections. |

# ...8.2.2.1. SSL/TLS connection arguments
With SSL/TLS, configuration depends on the database you are deploying.
The sslmode option determines whether, or with, what priority a secure SSL/TLS TCP/IP connection will be negotiated with the server. There are six modes:
| Mode | Description |
|---|---|
| sslmode | Determines whether, or with, what priority a secure SSL/TLS or TCP/IP connection is negotiated with the server. |
| *: disable | Your configuration only tries non-SSL/TLS connections. |
| *: allow | Your configuration first tries a non-SSL/TLS connection. Upon failure, tries an SSL/TLS connection. |
|
*: prefer | Your configuration first tries an SSL/TLS connection. Upon failure, tries a non-SSL/TLS connection. |
| *: require | Your configuration only tries an SSL/TLS connection. If a root CA file is present, it verifies the certificate in the same way as if verify-ca was specified. |
| *: verify-ca | Your configuration only tries an SSL/TLS connection, and verifies that the server certificate is issued by a trusted certificate authority (CA). |
| *: verify-full | Only tries an SSL/TLS connection, and verifies that the server certificate is issued by a trusted CA and that the requested server hostname matches that in the certificate. |
For more information on the valid arguments for PostgreSQL, see Database Connection Control Functions.
