Category:MySQL Server: Performance Schema Severity:S3 (Non-critical)
Version:8.0.0, 8.0.11 OS:Windows
Assigned to: Marc ALFF CPU Architecture:Any

File: Maximum allowed size is 3MB.
Description:
Privacy:

If the data you need to attach is more than 3MB, you should create a compressed archive of the data and a README file that describes the data with a filename that includes the bug number (recommended filename: mysql-bug-data-80523.zip) and upload one to sftp.oracle.com. A free Oracle Web (SSO) account (the one you use to login bugs.mysql.com) and a client that supports SFTP are required in order to access the SFTP server.

To upload the file to sftp.oracle.com:

  1. Open an SFTP client and connect to sftp.oracle.com. Specify port 2021 and remote directory /support/incoming/.
  2. Log in with your newly created Oracle Web account (email address) and password.
  3. Upload the archive to /support/incoming.
  4. Once you have uploaded the file, add a comment to this bug to notify us about it.
Example: sftp -oPort=2021 -oUser=email sftp.oracle.com:/support/incoming

Usage Notes: This directory is unlistable, which means that once you have uploaded your file, you will not be able to see it. A file cannot be uploaded more than once with the same filename. The filename must be changed before attempting to upload the file again. The filename should always start with mysql-bug- prefix. Files are retained on the SFTP server for 7 days and then permanently removed.
