Verifying the AWS SCT File Download

There are several ways you can verify the distribution file of the AWS SCT. The simplest is to compare the checksum of the file with the published checksum from AWS. As an additional level of security, you can use the procedures below to verify the distribution file, based on the operating system where you installed the file.

This section includes the following topics.

Topics

• Verifying the Checksum of the AWS SCT File
• Verifying the AWS SCT RPM Files on Fedora
• Verifying the AWS SCT DEB Files on Ubuntu
• Verifying the AWS SCT MSI File on Microsoft Windows
• Verifying the AWS SCT Application on Mac OS

Verifying the Checksum of the AWS SCT File

In order to detect any errors that could have been introduced when downloading or storing the AWS SCT compressed file, you can compare the file checksum with a value provided by AWS. AWS uses the SHA256 algorithm for the checksum.

To verify the AWS SCT distribution file using a checksum

1. Download the AWS SCT distribution file using the links in the Installing section.

2. Download the latest checksum file, called sha256Check.txt. For example, the file can appear like the following:

   
   Fedora   b4f5f66f91bfcc1b312e2827e960691c269a9002cd1371cf1841593f88cbb5e6
   Ubuntu   4315eb666449d4fcd95932351f00399adb6c6cf64b9f30adda2eec903c54eca4
   Windows  6e29679a3c53c5396a06d8d50f308981e4ec34bd0acd608874470700a0ae9a23
   MacOs    ed56d3ab49309e92ac4d2ef439d35449ac1326f470c23dc5866e1bf0a60b0e67                        
                       

3. Run the SHA256 validation command for your operating system in the directory that contains the distribution file. For example, the command to run on the Mac operating system is the following:

   shasum -a 256 aws-schema-conversion-tool-1.0.latest.zip

4. Compare the results of the command with the value shown in the sha256Check.txt file. The two values should match.

Verifying the AWS SCT RPM Files on Fedora

AWS provides another level of validation in addition to the distribution file checksum. All RPM files in the distribution file are signed by an AWS private key. The public GPG key can be viewed at amazon.com.public.gpg-key.

Installing JDBC Drivers on Linux

You can use the following steps to install the JDBC drivers on your Linux system for use with AWS SCT.

To install JDBC drivers on your Linux system

1. Create a directory to store the JDBC drivers in.

   PROMPT>sudo mkdir –p /usr/local/jdbc-drivers

2. Install the JDBC driver for your database engine using the commands shown following.

   Database Engine	Installation Commands
   Amazon Aurora (MySQL compatible)	PROMPT> cd /usr/local/jdbc-drivers PROMPT> sudo tar xzvf /tmp/mysql-connector-java-X.X.X.tar.gz
   Amazon Aurora (PostgreSQL compatible)	PROMPT> cd /usr/local/jdbc-drivers PROMPT> sudo cp -a /tmp/postgresql-X.X.X.jre7.tar .
   Microsoft SQL Server	PROMPT> cd /usr/local/jdbc-drivers PROMPT> sudo tar xzvf /tmp/sqljdbc_X.X.X_enu.tar.gz
   MySQL	PROMPT> cd /usr/local/jdbc-drivers PROMPT> sudo tar xzvf /tmp/mysql-connector-java-X.X.X.tar.gz
   Oracle	PROMPT> cd /usr/local/jdbc-drivers PROMPT> sudo mkdir oracle-jdbc PROMPT> cd oracle-jdbc PROMPT> sudo cp -a /tmp/ojdbc7.jar .
   PostgreSQL	PROMPT> cd /usr/local/jdbc-drivers PROMPT> sudo cp -a /tmp/postgresql-X.X.X.jre7.tar .

Storing Driver Paths in the Global Settings

After you have downloaded and installed the required JDBC drivers, you can set the location of the drivers globally in the AWS SCT settings. If you don't set the location of the drivers globally, the application asks you for the location of the drivers when you connect to a database.

To update the driver file locations

1. In the AWS SCT, choose Settings, and then choose Global Settings.

   

2. For Global settings, choose Drivers. Add the file path to the JDBC driver for your source database engine and your target Amazon RDS DB instance database engine.

   Note

   For Teradata, you specify two drivers separated by a semicolon.

   

3. When you are finished adding the driver paths, choose OK.

Updating the AWS SCT

AWS periodically updates the AWS SCT with new features and functionality. If you are updating from a previous version, create a new AWS SCT project and reconvert any database objects you are using.

You can check to see if updates exist for the AWS SCT.

To check for updates to AWS SCT

1. When in the AWS SCT, choose Help and then choose Check for Updates.

2. In the Check for Updates dialog box, choose What's New. If the link does not appear, you have the latest version.
