SSIS Integration Toolkit

The free developer license is fully functional within development tools such as SSDT-BI, BIDS, or Visual Studio. Its primary limitation is that it cannot be used to run the software outside of these tools.

Additionally, the free developer license should not be used for production purposes, including production data extraction or data loading.

Try opening Visual Studio by selecting "Run as Administrator".

When using SQL Server 2014, a cumulative update is required (Cumulative Update 2 or later, or any recent service packs). The following are the download links:

• Runtime - SQL Server 2014 Service Pack 1: https://www.microsoft.com/en-us/download/details.aspx?id=46694
• Design time - Microsoft SQL Server Data Tools - Business Intelligence for Visual Studio 2013: http://www.microsoft.com/en-ca/download/details.aspx?id=42313

This issue is caused by SSIS optimization behavior. It occurs when not all outputs are attached to a destination component.

You can resolve this issue using one of the following methods:

1. Change the RunInOptimizedMode property to False in the Properties window at the Data Flow level
2. Remove unused outputs by unchecking them on the General page of the JSON/XML Source/Extract component
3. Attach an SSIS destination component for each output.

Text fields are generally represented as "nvarchar" as a standard practice. The reason the length is set to 4000 is related to the web service interface used to communicate with the server (for example, Dynamics SL or Oracle CRM On Demand). The WSDL documents used to generate SSIS metadata do not specify a length for text fields. As a result, all text fields are defined with the maximum allowed length of 4000.

If a field exceeds 4000 characters, it may cause a buffer overflow. To resolve this, you can change the field type to DT_NTEXT using the SSIS Advanced Editor.

To fully utilize the BDD component, you need to increase the connection limit imposed by the Microsoft .NET Framework, which allows a maximum of 2 connections per host for service calls.

To override this limit, you must modify the DTExec.exe.config and DtsDebugHost.exe.config files under the DTS\binn folder by adding the following connectionManagement section:

<configuration>
   ...
   <system.net>
     <connectionManagement>
       <add address="*" maxconnection="100"/>
     </connectionManagement>
   </system.net>
</configuration>

The above configuration allows up to 100 simultaneous connections per host. You may adjust this number based on your needs. If you are running a 64-bit system, you must update the files under both the "Program Files" and "Program Files (x86)" folders. Note that these changes are not required for version 5.1 or later, as the limitation has been addressed programmatically.

When using the BDD component, keep in mind the following:

• Avoid using too many BDD distributions in a single data flow, as this may overload the server
• BDD uses the SSIS internal buffer to manage distribution, with a default size of 10,000 rows. This means distribution may not occur until a buffer is filled. For instance, the BDD component's second output will not receive anything if you have less than 10,000 records (9,947 records actually), and the third output will not receive anything until you have more than 19,894 records. If you are working on a small load, you must change the data flow task's DefaultBufferMaxRows property and give it a smaller number so that the BDD distribution happens sooner. SSIS Integration Toolkit (formerly SSIS Productivity Pack) as discussed in this blog post
• SSIS has an undocumented limit of 5 active buffers per data flow. Therefore, using more than 5 BDD branches in a single data flow will not improve performance
• To use more than 5 BDD components, split your data across multiple data flow tasks, with up to 5 BDD components per task.

When using SQL Server 2014, a cumulative update is required (Cumulative Update 2 or later, or a recent service pack).

This error is related to the package ProtectionLevel setting used when the SSIS package was saved. By default, SSIS packages use EncryptSensitiveWithUserKey. This means sensitive data, such as passwords, is encrypted using the package author's user key. When the package is executed by SQL Agent, it runs under a different account with a different user key, so the sensitive data cannot be decrypted.

To resolve this issue, you can configure the SQL Agent job and enter the password manually in SQL Server Management Studio (SSMS). Alternatively, you can change the package ProtectionLevel to EncryptSensitiveWithPassword and provide a PackagePassword. When configuring the SQL Agent job, enter the package password in the Command Line page.

The recommended best practice is to use the SSIS Package Configuration Wizard to create a configuration file for deployment and parameterize your connection manager. This allows you to keep the default ProtectionLevel and manage sensitive values through configurations instead.
