There doesn’t seem to be a daml-on-sql jar packaged with the latest release as with 1.18.1 ( we’re currently using [daml-on-sql-1.18.1.jar](https://github.com/digital-asset/daml/releases/download/v1.18.1/daml-on-sql-1.18.1.jar))

> **[Release 2.1.1 · digital-asset/daml](https://github.com/digital-asset/daml/releases/tag/v2.1.1)**
>
> See release notes for details.

> **[Release 1.18.1 · digital-asset/daml](https://github.com/digital-asset/daml/releases/tag/v1.18.1)**
>
> Find the release notes at https://daml.com/release-notes/1.18.1

As it stands, it seems daml-on-sql-1.18.1.jar is working fine. (but maybe I didn’t upgrade to 2.1.1 correctly).

The old daml-on-sql has been removed from Daml 2. Please see this prior thread for discussion of recommended setup for SQL-backed Daml 2 ledgers:

> To run Daml apps built with the SDK 1.x.x with database backing, there used to be a ledger implementation daml-on-sql.jar (cf. e.g., [Release 1.18.0 · digital-asset/daml · GitHub](https://github.com/digital-asset/daml/releases/tag/v1.18.0)) This doesn’t exist in the 2.x.x releases anymore (cf. e.g. [Release 2.1.0 · digital-asset/daml · GitHub](https://github.com/digital-asset/daml/releases/tag/v2.1.0)). What would I use instead to run a Daml 2.x app in a ledger with database backing?
