Google Search Appliance: Feeds Protocol Developer’s Guide 33

Troubleshooting

Here are some things to check if a URL from your feed does not appear in the index. To see a list of

known and fixed issues, see the latest release notes for each version.

Error Messages on the Feeds Status Page

If the feeds status page shows “Failed in error” you can click the link to view the log file.

ProcessFeed: parsing error

This message means that your XML file could not be understood. The following are some possible

causes of this error:

• There is an error in the DOCTYPE line in your XML file. This line should be:

<!DOCTYPE gsafeed

PUBLIC "-//Google//DTD GSA Feeds//EN""">

• You have not escaped the ampersand or other reserved characters in a URL in your XML file.

• You have included content that requires base64 encoding. See “Providing Content in the Feed” on

page 11.

If none of the above are the cause of the error, run

xmllint

against your XML file to check for errors in

the XML. The

xmllint

program is included in Linux distributions as part of the

libxml2

package.

The following is an example that shows how you would use

xmllint

to test a feed named

full-

feed.xml

$ xmllint -noout -valid full-feed.xml; echo $?

The return code of zero indicates that the document is both valid and well-formed.

If the

xmllint

command fails and displays the

parsing error

message, ensure that you have the

correct DTD file, or you can remove the

-valid

flag from the

xmllint

command line so that the

xmllint

command doesn’t try to validate the XML file’s elements. For more information on the DTD, see

“Google Search Appliance Feed DTD” on page 41.

Feed Push is Not Successful

Before a search appliance can start processing a feed, you need to successfully push a feed to port

19900.

If the feed push is not successful, check the following:

• List the IP address of the computer that hosts the feed client in the List of Trusted IP Addresses.

For more information, see “Pushing a Feed to the Google Search Appliance” on page 27.

• Verify that the feed client connects to port 19900 on the correct IP address.

• Verify that port 19900 is reachable on the search appliance by running

tracepath applianceIP/

19900

from the Linux command line.

• Check with your network team for firewall or connectivity issues to ensure access to port 19900.
