The clearData task can remove data that is stored in both the search index and the Information Store database. You can use this task to remove test data from a system.
About this task
In a multiple server deployment, run the
clearData and
clearSearchIndex tasks from the
Liberty server.In a deployment that provides
high availability, stop and start each Liberty
server in your environment but run
clearData and
clearSearchIndex on the Liberty
server that you used to create the database
only.
Important: These instructions
are designed to remove data that is used for test
purposes. Do not use the task to clear data in a
production system without backing up your data.
For more information about backing up your data,
see
Backing up a
deployment.
Procedure
- On the Liberty server, in a command
prompt navigate to the
toolkit\scripts
directory.
-
Stop the deployment:
-
To clear data and the search index, run the
following command:
setup -t clearData --hostname liberty.host-name
- Where
liberty.hostname is the
hostname of the Liberty server where you are
running the command, and matches the value for the
host-name attribute of the
<application> element in the
topology.xml file.
- A message is displayed when you run the task to confirm that you want to complete the action. Enter Y to continue. The data and the search index are removed from the system.
If you run the clearData task
with the --scripts argument, the
scripts for clearing the Information Store
database are generated in the
toolkit\scripts\database\<database
dialect>\InfoStore\generated\clearData
directory, but not run. You can then inspect the
scripts before they are run, or run the scripts
yourself. To run the scripts yourself, run them in
their numbered order to clear the data from your
system.
To generate the scripts for the task,
run:
setup -t clearData --scripts
After
you run the scripts manually, clear the search
index:
setup -t clearSearchIndex --hostname liberty.host-name
-
Start the deployment of i2 Analyze.
