MSSQL Linux operations in DCT

This section describes how to manage MSSQL Linux connector infrastructure and data sources by using Delphix Data Control Tower (DCT). It covers authentication, connecting an engine, connector management, environment configuration, and dSource creation.

Overview

DCT provides a centralized control plane for managing MSSQL Linux data operations across one or more Delphix Continuous Data Engines. Using DCT, you can use onboard infrastructure, discover MSSQL Linux installations, define source configurations, and ingest data into managed storage for downstream virtualization workflows.

Key components

  • Continuous Data Engine

    Executes MSSQL Linux for discovery, ingestion, and snapshot operations. For more information, read Connect a Continuous Data Engine in DCT.

  • MSSQL Linux connector

    A JSON-based connector that enables the engine to detect MSSQL Linux  installations on registered hosts. For more information, read Upload the Connector.json in DCT.

  • Infrastructure connections (environments)

    Registered MSSQL Linux hosts that DCT communicates with over SSH.

  • Source configurations

    Logical definitions that identify which MSSQL Linux instance can be ingested as a dSource. For more information, read Create a source configuration for Connectors in DCT.

  • dSources

    Managed representations of MSSQL Linux databases used to take snapshots, create bookmarks, link dSources, and provision VDBs.

  • VDBs

    Manage a VDB which is provisioned from a dSource or a VDB snapshot.

Prerequisites

  • Access to DCT with appropriate administrative permissions

  • A running Delphix Continuous Data Engine

  • Network connectivity between DCT, the engine, and MSSQL Linux hosts

  • Valid MSSQL Linux OS and database credentials

  • MSSQL Linux connector JSON file available for upload

Limitations

  • Connector downgrades are not supported. Uploading a lower connector version is rejected at the engine level.

  • Source configurations linked to an active dSource cannot be deleted.

  • The Refresh prior to snapshot option must be enabled when creating a MSSQL Linux dSource; disabling it causes linking to fail.
