Clearing data from the system

During development, it is common to need to clear data from the i2 data stores.

Before you begin

This process can permanently remove data from your system, ensure that no data is in the system that you want to keep.

For information about making a backup of your deployment, see Backing up a deployment.

Stopping Liberty

Run the following command on the Liberty server to stop Liberty:

docker exec -u i2analyze liberty /opt/i2/i2analyze/toolkit/scripts/setup -t stopLiberty

The console output from the stopLiberty task is output directly to the console.

Clear data

To remove data from both the search index and the database, you can use the clearData toolkit task. For more information, see Clearing data from the system.

To clear the data, you can run the command from the Admin client or Liberty server. In the distributed deployment example, the admin_client container is used to run the command. The admin_client container includes the i2 Analyze toolkit and a database management client installation. You must run commands that modify the database and Solr and ZooKeeper from this container.

To clear the data, run the following command:

docker exec -u i2analyze -it admin_client /opt/i2/i2analyze/toolkit/scripts/setup -t clearData --hostname admin_client.eianet

The database is now clear of data and the search index is now empty.

The database still exists with the structure from the schema. If you want to make destructive schema changes, follow the instructions in Resetting the system.

Restarting your system

To restart Liberty, run the following command:

docker exec -u i2analyze liberty /opt/i2/i2analyze/toolkit/scripts/setup -t startLiberty

The console output from the startLiberty task is output directly to the console.

Liberty is now started and you can connect to i2 Analyze.

Testing the deployment

Connect to i2 Analyze and search for data. If you perform a wildcard search for *, all of the data in your system is returned. After you run clearData, this search returns no results.
