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.
Creating Connection Manager configuration files
Parameters and format of the Connection Manager configuration fileThe following example shows the format of the Connection Manager configuration file, and shows which parameters and attributes can be set for each connection-unit type.
LOCAL_IP Connection Manager configuration parameterThe LOCAL_IP parameter specifies IP addresses to monitor on the computer that is running the Connection Manager. The LOCAL_IP parameter is used with the FOC parameter's PRIORITY attribute to determine if database-failover occurs during a partial network failure.

LOCAL_IP Connection Manager configuration parameter

The LOCAL_IP parameter specifies IP addresses to monitor on the computer that is running the Connection Manager. The LOCAL_IP parameter is used with the FOC parameter's PRIORITY attribute to determine if database-failover occurs during a partial network failure.

Syntax

Usage

The LOCAL_IP parameter is optional, and applies to CLUSTER connection units.

You must list the IP address of each network interface card to be monitored.

Example

In the following example, the Connection Manager monitors the network connection between its host and the primary server of a cluster through the network interface cards that have IP addresses of 192.0.2.0 and 192.0.2.1:

LOCAL_IP 192.0.2.0,192.0.2.1
