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.
ENCRYPT_MAC configuration parameterUse the ENCRYPT_MAC configuration parameter to control the level of message authentication code (MAC) generation. This configuration parameter is used only for Enterprise Replication and High-Availability Data Replication.

ENCRYPT_MAC configuration parameter

Use the ENCRYPT_MAC configuration parameter to control the level of message authentication code (MAC) generation. This configuration parameter is used only for Enterprise Replication and High-Availability Data Replication.

onconfig.std value

Not set

values

off = Does not use MAC generation

low = Uses XOR folding on all messages

medium = Uses SHA1 MAC generation for all messages that are greater than 20 bytes long and XOR folding on smaller messages

high = Uses SHA1 MAC generation on all messages.

example

ENCRYPT_MAC medium,high

takes effect

For HDR: when the database server is shut down and restarted

For Enterprise Replication: when Enterprise Replication is started

Usage

The level is prioritized to the highest value. For example, if one node has a level of high and medium enabled and the other node has only low enabled, then the connection attempt fails. Use the off entry between servers only when a secure network connection is guaranteed.
