.DTT File

What is a .DTT file?

There are two main types of .DTT files:

• IBM i Data Transfer To IBM i files: These files are created by the Data Transfer To IBM i application in IBM i. They store information for data transfer to an existing database file definition on the system. The application may also create a TFR file instead of the DTT file.
• Affymetrix data files: These files are created by several software tools from Affymetrix, such as the Command Console Software (AGCC), GeneChip Operating Software (GCOS), or Data Transfer Tool (DTT). They contain the raw data files (CEL), plus some additional files (such as the washing and staining protocols, library files, etc.). Affymetrix data files are used to store microarray data. They are typically used in gene expression studies.

In this article, we mention to .DTT file as a Data Transfer To IBM i application file. It is used to store information for data transfer to an existing database file definition on the IBM i system. The Data Transfer To IBM i application is a tool that allows users to transfer data from other platforms to IBM i, or between different IBM i systems.

.DTT files typically contain the following information:

• The database file definition that the data will be transferred to
• The data fields that will be transferred
• The mapping between the data fields in the source file and the data fields in the target database file
• Any additional information that is needed to perform the data transfer, such as filter criteria or conversion rules

To use a .DTT file, users must first open the Data Transfer To IBM i application and select the .DTT file. The application will then display the information about the data transfer, and users can make any necessary changes. Once the users are satisfied with the data transfer settings, they can click the "Start Transfer" button to begin the process.

.DTT files are a convenient and efficient way to transfer data to and from IBM i systems. They can be used to transfer large volumes of data quickly and easily, and they can also be used to automate data transfer processes.

Here are some examples of how .DTT files can be used:

• To migrate data from an on-premises ERP system to IBM i
• To import data from a CSV file into an IBM i database
• To transfer data between different IBM i databases
• To export data from an IBM i database to a cloud-based storage system
• To automate the daily transfer of data from a CRM system to an IBM i database

If you are working with IBM i systems, it is important to understand what .DTT files are and how to use them. .DTT files can be a valuable tool for transferring data to and from IBM i systems quickly, easily, and efficiently.

How to open a .DTT file?

To open a .DTT file, you can use the Data Transfer To IBM i application. This application is available for download from the IBM website.

Once you have installed the Data Transfer To IBM i application, you can open a .DTT file by following these steps:

1. Open the Data Transfer To IBM i application.
2. Click the "File" menu and select "Open".
3. Navigate to the .DTT file that you want to open and select it.
4. Click the "Open" button.

The Data Transfer To IBM i application will then display the information about the data transfer. You can make any necessary changes to the data transfer settings, and then click the "Start Transfer" button to begin the process.

If you do not have the Data Transfer To IBM i application installed, you may be able to open a .DTT file using a text editor such as Notepad or TextEdit. However, this will only allow you to view the contents of the file, and you will not be able to perform a data transfer.

Here are some additional tips for opening .DTT files:

• If you are using the Data Transfer To IBM i application, make sure that you have the latest version installed. IBM releases updates to the application regularly, and these updates often include new features and bug fixes.
• If you are trying to open a .DTT file on a computer that does not have the Data Transfer To IBM i application installed, you can try using a text editor such as Notepad or TextEdit. However, as mentioned above, this will only allow you to view the contents of the file, and you will not be able to perform a data transfer.
• If you are having trouble opening a .DTT file, try contacting IBM support for assistance.

What is the difference between a .DTT file and a .TFR file?

The main difference between a .DTT file and a .TFR file is that a .DTT file is used to store information for data transfer to an existing database file definition on the IBM i system, while a .TFR file is used to store information for data transfer to a database file that does not yet exist on the IBM i system.

.DTT files contain the following information:

• The database file definition that the data will be transferred to
• The data fields that will be transferred
• The mapping between the data fields in the source file and the data fields in the target database file
• Any additional information that is needed to perform the data transfer, such as filter criteria or conversion rules

.TFR files contain the same information as .DTT files, but they also contain the following additional information:

• The name of the database file that the data will be transferred to
• The type of database file that the data will be transferred to
• The size of the database file that the data will be transferred to

.TFR files are typically used to migrate data from other platforms to IBM i, or to create new database files on IBM i.

Here is a table that summarizes the key differences between .DTT files and .TFR files:

How to transfer data to an IBM i database using a .DTT file?

To transfer data to an IBM i database using a .DTT file, you can follow these steps:

1. Create a .DTT file. You can do this using the Data Transfer To IBM i application, or by creating a text file and saving it with the .DTT file extension.
2. Open the .DTT file in the Data Transfer To IBM i application.
3. Select the database file that you want to transfer the data to.
4. Select the data fields that you want to transfer.
5. Map the data fields in the source file to the data fields in the target database file.
6. Specify any additional information that is needed to perform the data transfer, such as filter criteria or conversion rules.
7. Click the "Start Transfer" button to begin the data transfer.

The Data Transfer To IBM i application will then transfer the data to the IBM i database. The amount of time it takes to transfer the data will depend on the size of the data set and the speed of the network connection.

Here are some additional tips for transferring data to an IBM i database using a .DTT file:

• Make sure that you have the latest version of the Data Transfer To IBM i application installed. IBM releases updates to the application regularly, and these updates often include new features and bug fixes.
• If you are transferring a large volume of data, you may want to consider using a batch job to perform the transfer. This will allow you to transfer the data without having to keep the Data Transfer To IBM i application open.
• If you are having trouble transferring data, try contacting IBM support for assistance.
