-24960: ERR_DBRUN - database is running 

Explanation:

The status of the database is either WARM or COLD , and the DBM server command you have used is invalid when the database has this status.

User action:

First of all, make sure the database is OFFLINE and then re-execute the command.

Shutting down the database to OFFLINE breaks the connection to all users logged on to the database or ends all programs that are running on it.
