K-Safety Support in Administration Tools
The Administration Tools allow certain operations on a K-Safe database, even if some nodes are unresponsive.
The database must have been marked as K-Safe using the MARK_DESIGN_KSAFE function.
The following management functions within the Administration Tools are operational when some nodes are unresponsive.
Note: Vertica users can perform much of the below functionality using the Management Console interface. See Management Console and Administration Tools for details.
- View database cluster state
- Connect to database
- Start database (including manual recovery)
- Stop database
- Replace node (assuming node that is down is the one being replaced)
- View database parameters
- Upgrade license key
The following operations work with unresponsive nodes; however, you might have to repeat the operation on the failed nodes after they are back in operation:
- Distribute config files
- Install external procedure
- (Setting) database parameters
The following management functions within the Administration Tools require that all nodes be UP in order to be operational:
- Create database
- Run the Database Designer
- Drop database
- Set restart policy
- Roll back database to Last Good Epoch
