The dropDatabases task can remove not only the data, but also the underlying structures such as tables from your database management system. The deleteSolrCollections task can remove any Solr collections from the system.
Before you begin
To drop the databases, you must ensure that there are no active connections to them.
About this task
In a multiple-server environment, run all
toolkit tasks from the Liberty server.In a
deployment that provides high availability, use
the documentation from your database management
system to remove the Information Store database
from each database server in your deployment
instead of the dropDatabases
toolkit task.
In a deployment that provides
high availability, stop and start each Liberty
server in your environment but run
clearSearchIndex on the Liberty
server that you used to create the database
only.
Important: These instructions
are designed to remove databases that are used for
test purposes. Do not use the task to remove
databases in a production system without backing
up your data. For more information about backing
up your data, see
Backing up a
deployment.

setup -t dropDatabases --hostname liberty.host-name
setup -t deleteSolrCollections --hostname liberty.host-name
Here,
liberty.hostname is the hostname of the Liberty server where you are running the command. It matches the value for the
host-name attribute of the
<application> element in the
topology.xml file.
