Actian Avalanche 또는 Vector와 함께 Looker를 사용하려면 인그레스 드라이버를 구성해야 합니다. 이 안내에서는 looker-open-source GitHub 페이지에 제공된 예시와 유사한 시작 스크립트를 사용한다는 가정 하에 이 프로세스를 설명합니다.
Ingres 드라이버 JAR을 가져와 시작 프로세스의 일부로 포함한 다음, Looker에 액세스 권한을 요청하는 옵션을 추가해야 합니다.
네트워크 트래픽 암호화
Looker 애플리케이션과 데이터베이스 사이에 네트워크 트래픽을 암호화하는 것이 가장 좋습니다. 안전한 데이터베이스 액세스 사용 설정 문서 페이지에 설명된 옵션 중 하나를 고려해 보세요.

These instructions describe that process, assuming use of a startup script that is similar to the examples that are provided on the [looker-open-source GitHub page](https://github.com/looker-open-source/customer-scripts/tree/master/startup_scripts).\n\nYou will need to acquire an Ingres driver JAR, include it as part of the startup process, and add an option to tell Looker to access it.\n\nEncrypting network traffic\n--------------------------\n\nIt is a best practice to encrypt network traffic between the Looker application and your database. Consider one of the options described on the [Enabling secure database access](/looker/docs/enabling-secure-db-access) documentation page.\n\nInstalling the Ingres JDBC driver\n---------------------------------\n\nFollow the steps on the [Unpackaged JDBC drivers](/looker/docs/unpackaged-jdbc-drivers) documentation page using the following values:\n\n**driver symbol** : `ingres`\n\n**driver entry**: \n\n - name: ingres\n dir_name: ingres\n module_path: com.ingres.jdbc.IngresDriver\n\nFor the [step to put the driver in your dialect's directory](/looker/docs/unpackaged-jdbc-drivers#driver_directory), the path to this file will look like this: `looker/custom_jdbc_drivers/ingres/iijdbc.jar`.\n\nCreating the Looker connection to your database\n-----------------------------------------------\n\nFollow these steps to create the connection from Looker to your database:\n\n1. In the **Admin** section of Looker, select **Connections** , and then click **Add Connection**.\n2. Select **Actian Avalanche** or **Vector** from the **Dialect** drop-down menu.\n\n | **Note:** If you are on a [Looker (Google Cloud core)](/looker/docs/looker-core-overview) instance and you don't see your dialect listed in the **Dialect** drop-down menu, see the [Looker (Google Cloud core) documentation](/looker/docs/looker-core-dialects#supported_dialects_for) to verify that the dialect is supported for Looker (Google Cloud core) instances.\n3. Fill out the connection details. The majority of the settings are common to most database dialects. See the [Connecting Looker to your database](/looker/docs/connecting-to-your-db) documentation page for information.\n\n4. To verify that the connection is successful, click **Test** . See the [Testing database connectivity](/looker/docs/testing-db-connectivity) documentation page for troubleshooting information.\n\n5. To save these settings, click **Connect**.\n\nEnabling PDT support\n--------------------\n\nIt is possible to use [persistent derived tables (PDTs)](/looker/docs/derived-tables#persistent_derived_table) on your database using the [**PDT Overrides**](/looker/docs/connecting-to-your-db#configuring_separate_login_credentials_for_pdt_processes) section in the [**Connection Settings** page](/looker/docs/admin-panel-database-connections#adding_connections).\n\nTo enable PDTs:\n\n1. Create a PDT user in your database for use with the scratch schema, for example `looker_scratch`.\n\n2. Create a group in your database such as `looker_pdt_group`.\n\n3. Add both the regular Looker user and the Looker PDT user to the new group.\n\n4. GRANT SELECT on all tables in the regular Looker user's schema to the PDT user.\n\n5. In the Looker **Connection Settings** page, in the **PDT Overrides** section, enter the PDT user information.\n\n6. The PDT user then runs a GRANT SELECT to the `looker_pdt_group` for every table it creates.\n\nFeature support\n---------------\n\nFor Looker to support some features, your database dialect must also support them.\n\n### Actian Avalanche\n\nActian Avalanche supports the following features as of Looker 25.14:\n\n### Vector\n\nVector supports the following features as of Looker 25.14:"]]
