Troubleshooting Applications on Amazon RDS

Amazon Relational Database Service; provides specific and descriptive errors to help you troubleshoot problems while interacting with the Amazon RDS API.

Retrieving Errors

Typically, you want your application to check whether a request generated an error before you spend any time processing results. The easiest way to find out if an error occurred is to look for an Error node in the response from the Amazon RDS API.

XPath syntax provides a simple way to search for the presence of an Error node, as well as an easy way to retrieve the error code and message. The following code snippet uses Perl and the XML::XPath module to determine if an error occurred during a request. If an error occurred, the code prints the first error code and message in the response.

Copy
use XML::XPath; my $xp = XML::XPath->new(xml =>$response); if ( $xp->find("//Error") ) {print "There was an error processing your request:\n", " Error code: ", $xp->findvalue("//Error[1]/Code"), "\n", " ", $xp->findvalue("//Error[1]/Message"), "\n\n"; }

Troubleshooting Tips

We recommend the following processes to diagnose and resolve problems with the Amazon Relational Database Service API.

  • Verify that Amazon Relational Database Service is operating normally in the region you are targeting by visiting http://status.aws.amazon.com.

  • Check the structure of your request

    Each Amazon Relational Database Service operation has a reference page in the Amazon RDS API Reference. Double-check that you are using parameters correctly. In order to give you ideas regarding what might be wrong, look at the sample requests or user scenarios to see if those examples are doing similar operations.

  • Check the forum
