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.
LOGFILE Connection Manager configuration parameterThe LOGFILE parameter specifies the name and location of the Connection Manager log file.

LOGFILE Connection Manager configuration parameter

The LOGFILE parameter specifies the name and location of the Connection Manager log file.

Syntax

Usage

The LOGFILE parameter is optional, and applies to the following connection units:

CLUSTER
GRID
REPLSET
SERVERSET

The path and file name of the log file display when the Connection Manager is started, and the log file is continuously updated with status information while the Connection Manager is running. If multiple Connection Managers are installed on the same host, specify a different path and file name for each Connection Manager.

Make sure that the directory for the log file exists, and that access to the file is enabled for the user that starts the Connection Manager.

If the LOGFILE parameter is not set, the Connection Manager creates a log file in the $INFORMIXDIR/tmp directory, with a name of connection_manager_name.process_ID.log.

Example

In the following example, the Connection Manager logs proxy-mode SLA information about data send-and-receive activities between clients and the Connection Manager. The information is logged to $INFORMIXDIR/tmp/my_cm.log.

LOG 2
LOGFILE $INFORMIXDIR/tmp/my_cm.log
