  • Third-party components
  • Change Data Capture (CDC)
  • SSIS Scale Out

For other limitations and known issues with SSIS on Linux, see SQL Server on Linux: Known issues.

Supported and unsupported components

The following built-in Integration Services components are supported on Linux. Some of them have limitations on the Linux platform. Built-in components that aren't listed here aren't supported on Linux.

Supported control flow tasks

  • Bulk Insert Task
  • Data Flow Task
  • Data Profiling Task
  • Execute SQL Task
  • Execute T-SQL Statement Task
  • Expression Task
  • FTP Task
  • Web Service Task
  • XML Task

Control flow tasks supported with limitations

Task Limitations
Execute Process task Only supports in-process mode.
File System task The Move directory and Set file attributes actions aren't supported.
Script task Only supports standard .NET Framework APIs.
Send Mail task Only supports anonymous user mode.
Transfer Database task UNC paths aren't supported.

Supported and unsupported maintenance plan tasks

In a SQL Server maintenance plan, you can typically use various SSIS tasks.

The following maintenance plan tasks aren't supported on Linux:

  • Notify Operator
  • Execute SQL Server Agent Job

The following maintenance plan tasks are supported on Linux:

  • Check Database Integrity
  • Shrink Database
  • Reorganize Index
  • Rebuild Index
  • Update Statistics
  • Clean Up History
  • Back Up Database
  • T-SQL Statement

Supported control flow containers

  • Sequence Container
  • For Loop Container
  • Foreach Loop Container

Supported data flow sources and destinations

  • Raw File source and destination
  • XML Source

Data flow sources and destinations supported with limitations

Component Limitations
ADO.NET source and destination Only support the SQLClient data provider.
Flat File source and destination 1. Only support Windows-style file paths, to which the default path mapping rule is applied. For example, D:\home\ssis\travel.csv becomes /home/ssis/travel.csv.

2. Azure File share that mounted on Red Hat 7 isn't supported.
OData source Only supports Basic authentication.
ODBC source and destination Supports 64-bit Unicode ODBC drivers on Linux. Depends on the UnixODBC driver manager on Linux.
OLE DB source and destination Only support SQL Server Native Client 11.0 and Microsoft OLE DB Provider for SQL Server.

Supported data flow transformations

  • Aggregate
  • Audit
  • Balanced Data Distributor
  • Character Map
  • Conditional Split
  • Copy Column
  • Data Conversion
  • Derived Column
  • Export Column
  • Fuzzy Grouping
  • Fuzzy Lookup
  • Import Column
  • Lookup
  • Merge
  • Merge Join
  • Multicast
  • Pivot
  • Row Count
  • Slowly Changing Dimension
  • Sort
  • Term Lookup
  • Union All
  • Unpivot

Data flow transformations supported with limitations

Component Limitations
OLE DB Command transformation Same limitations as the OLE DB source and destination.
Script component Only supports standard .NET Framework APIs.

Supported and unsupported log providers

All the built-in SSIS log providers are supported on Linux except the Windows Event Log provider.

The SQL Server log provider supports only SQL Authentication; it doesn't support Windows Authentication.

The SSIS log providers for Text files, for XML files, and for SQL Server Profiler write their output to a file that you specify. The following considerations apply to the file path:

  • If you don't provide a path, the log provider writes to the current directory of the host. If the current user doesn't have permission to write to the current directory of the host, the log provider raises an error.
  • You can't use an environment variable in a file path. If you specify an environment variable, the literal text that you specify appears in the file path. For example, if you specify %TMP%/log.txt, the log provider appends the literal text /%TMP%/log.txt to the current host directory.
