Troubleshooting applications on Amazon RDS
Amazon RDS provides specific and descriptive errors to help you troubleshoot problems while interacting with the Amazon RDS API.
For information about troubleshooting for Amazon RDS DB instances, see Troubleshooting for Amazon RDS.
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.
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 RDS API.
-
Verify that Amazon RDS is operating normally in the Amazon Region you are targeting by visiting http://status.www.amazonaws.cn
. -
Check the structure of your request
Each Amazon RDS 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.
