Dropping Database Post Uninstall
Regardless of the uninstallation method used for Platforms, Aggregator-Collector hybrids, or Standalone Aggregators, it is important to drop the node from the MySql workbench that was previously configured.
Please Note: Uninstalling a Standalone Collector does not require this step to be completed.
1. Open the [MySQL Workbench] application on the local host computer.
2. Located inside the left window pane titled [Schemas] right-click on the node’s entry and select [Drop Schema] from the options that appear.
3. A pop-up box will appear, requesting confirmation to drop the node from the database. Click the OK button to complete the process.
Please Note: If any other nodes are uninstalled, this process will need to be completed for each node that is dropped.
Linux
This is the uninstallation outline for the Linux platform.
Uninstalls require that a terminal window is available where commands may be entered. One of two commands included with Linux distribution are used, depending on which distribution the application is installed, and the package name for your application.
- For Debian based distributions, use dpkg –r {packagename}
- For RPM based distributions, use rpm –e {packagename}
See Supported Platforms for the list of currently-supported Linux distributions.
This chart shows the package name to use for each application type:
| Application | Package Name |
| Platform | aparavi-data-ia-platform |
| Collector | aparavi-data-ia-collector |
| Aggregator | aparavi-data-ia-aggregator |
| Aggregator-Collector | aparavi-data-ia-aggregator-collector |
The command to uninstall must run as root or as a sudo command. Here are two examples using each of the two possible command types.
- On Ubuntu, the command to uninstall an Aggregator:
sudo dpkg –r aparavi-data-ia- aggregator collector
- On CentOS, the command to uninstall a Collector:
sudo rpm -e aparavi-data-ia-collector
