accidentally reset preview

[8年前 に ildar sl によって更新されました。]

Hi!

I accidentally reset preview and thumbnail files for Documents and Media.
How to programmatically generate all files (mp3,pdf,images,docx,xls .....) over again?
Not really go to all pages specially what resources would be generated

Hi ildar,

take a look at this post: https://www.liferay.com/community/forums/-/message_boards/view_message/62264455.

Hi Juan.

Thank you! Turned out en masse to convert files.
Now another problem...
Among the documents was a bad file. During conversion gave this information:

ERROR [com.liferay.portal.kernel.process.ProcessUtil-4][LoggingOutputProcessor:59] **** Warning: File has an invalid xref entry: 2. Rebuilding xref table.
ERROR [com.liferay.portal.kernel.process.ProcessUtil-4][LoggingOutputProcessor:59] **** Warning: stream operator isn't terminated by valid EOL.
ERROR [com.liferay.portal.kernel.process.ProcessUtil-4][LoggingOutputProcessor:59] **** Warning: stream operator isn't terminated by valid EOL.

ERROR [com.liferay.portal.kernel.process.ProcessUtil-4][LoggingOutputProcessor:59] **** This file had errors that were repaired or ignored.
ERROR [com.liferay.portal.kernel.process.ProcessUtil-4][LoggingOutputProcessor:59] **** The file was produced by:

ERROR [com.liferay.portal.kernel.process.ProcessUtil-4][LoggingOutputProcessor:59] **** specification.

Then delete the file.
But somewhere the information in the database was, as afterwards there are constant errors:

The database did not find the information about successfully converted files. Where remove the remnants of the information about the PDF file?

Hi ildar,

it's a very bad idea to remove data using database. You can use the right API through Control Panel -> Server administration -> Script, or just remove that file from Documents & Media and all their previews will be removed too.
