18.5.2 Configuring Temporary File Handling

Configure how a background execution chain handles temporary files from upload items.

Processing user-uploaded files in the background is a common use case when the processing may be long-running or the user does not need to wait for the result. Use the Temporary File Handling property on the execution chain to control the behavior of user-uploaded files in temporary storage. Supported values of this setting include:

• Ignore – files remain in the user session for processing,
• Move – files move to the background execution chain's new session, or
• Copy – files remain in the user session and are copied to the new background session.

When using Move or Copy, set the additional property Temporary File Items to a comma-separated list of File Upload or Image Upload items whose temporary files you want to affect. The background session works with the files in the same way as in the user session using the APEX_APPLICATION_TEMP_FILES table.
