Webform Server uses the Access Control Database to monitor the status of active forms.
The Access Control Database allows Webform Server to process and monitor multiple forms from multiple users. The Access Control Database also maintains security for Webform Server, ensuring that forms and other documents are delivered and updated only by the client session that owns the form.
The following SQL databases are supported for use as the Access Control Database:
- IBM® DB2 Universal Database™
Note: Do not use Derby as a production database. Use Derby for development and testing purposes only.
Each Translator contains a Cache Cleaner process that periodically examines the Access Control Database. The Cache Cleaner removes records of forms that are no longer active. The process ensures that the database does not become cluttered with stale data.
Configuration parameters for the Access Control Database are in the translator.properties
file. The settings that affect the Access Control Database are as follows:
