# Durable Subscribers

This page shows the durable subscribers that are running on your JMS topics. WebLogic JMS stores durable subscribers in a persistent, disk-based file store or JDBC-accessible database until the message has been delivered to the subscribers or has expired, even if those subscribers are not active when the message is delivered.

- For more destination monitoring information, see Active JMS Destinations.
- For more information on creating durable subscribers, see "Developing a WebLogic JMS Application" in Programming WebLogic JMS.
