Uninstalling a Database Cluster
During uninstallation, PTK will check whether the cluster is in the running status. A cluster in the running status cannot be uninstalled. You need to stop the cluster and then uninstall the cluster.
Note: Once a database is uninstalled, it cannot be recovered. Please execute operation with caution.
You can run the ptk uninstall -n CLUSTER_NAME command on the server where PTK is installed to uninstall a cluster.
To uninstall a cluster, you need to specify the cluster name, you can run the ptk ls command to query the cluster name.
During uninstallation, PTK will ask you whether to delete the cluster topology information, system user, and database data.
Please perform operations with cautions, avoiding data loss due to incorrect operations.
If you are sure to delete the data directory, PTK delete only the data directory and will not delete its parent directory. You need to manually delete the parent directory.
