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 ReferenceThe HCL OneDB™ Administrator's Reference includes comprehensive descriptions of HCL OneDB™ configuration parameters, the system-monitoring interface (SMI) tables in the sysmaster database, the syntax of database server utilities such as onmode and onstat, logical-log records, disk structures, event alarms, and unnumbered error messages.
Configuring and monitoring HCL OneDB™
Database configuration parametersThe HCL OneDB™ database server uses a configuration file, which is called the onconfig file, during initialization. This file contains default configuration parameter values. You can modify the parameter values to improve performance and other characteristics of the instance or database.
MSGPATH configuration parameterUse the MSGPATH configuration parameter to specify the full path name of the message-log file. The database server writes status messages and diagnostic messages to this file during operation.

MSGPATH configuration parameter

Use the MSGPATH configuration parameter to specify the full path name of the message-log file. The database server writes status messages and diagnostic messages to this file during operation.

onconfig.std value

On UNIX™: $INFORMIXDIR/tmp/online.log

On Windows™: %INFORMIXDIR%\online.log

On Windows, if you create a server instance during installation: %INFORMIXDIR%\server_name.log. The server_name is the name of server in the program group and the value of the INFORMIXSERVER environment variable.

values

The path name of the online.log file.

takes effect

After you edit your onconfig file and restart the database server.

When you reset the value dynamically in your onconfig file by running the onmode -wf command.

When you reset the value in memory by running the onmode -wm command.

Usage

If the file that MSGPATH specifies does not exist, the database server creates the file in the specified directory. If the directory that MSGPATH specifies does not exist, the database server sends the messages to the system console.

If the file that MSGPATH specifies does exist, the database server opens it and appends messages to it as they occur.
