AdministeringIn addition to administering the database server, you can tune performance, replicate data, and archive data.
System administrationThese topics contain concepts, procedures, and reference information for database and database server administrators to use for managing and tuning HCL OneDB™ database servers.
Administrator's GuideThe HCL OneDB™ Administrator's Guide provides the information required to administer HCL OneDB™.
High availability and scalabilityA successful production environment requires database systems that are always available, with minimal if any planned outages, and that can be scaled quickly and easily as business requirements change.
Connection management through the Connection ManagerConnection Managers can control automatic failover for high-availability clusters, monitor client connections and direct requests to appropriate database servers, act as proxy servers and handle client/server communication, and prioritize connections between application servers and the primary server of a high-availability cluster. Connection Managers support high-availability clusters, replicate sets, server sets, and grids.
Configuring connection managementTo configure connection management, you must install software, set environments and connectivity information, create Connection Manager configuration files, and run the oncmsm utility.
Stopping connection managementWhen you no longer want a Connection Manager to manage connection units, run the oncmsm utility to stop the Connection Manager instance.

Stopping connection management

When you no longer want a Connection Manager to manage connection units, run the oncmsm utility to stop the Connection Manager instance.

About this task

If you are using multiple Connection Managers, you can run onstat -g cmsm to display the names of Connection Manager instances.

Procedure

Log on to the computer on which the Connection Manager instance is running.
Run the oncmsm utility with the -k parameter.
For example:
```
oncmsm -k connection_manager_name
```
If quality of data (QOD) monitoring is turned on, and you want to stop it, run the cdr stop qod command on the master server.
For example:
```
cdr stop qod -c server_1
```

Results

The Connection Manager stops.

What to do next

To unistall a stopped Connection Manager from a Windows™ operating system, run the following command on the computer that the Connection Manager is installed on:

oncmsm -u connection_manager_name
