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_SWITCH configuration parameterUse the ENCRYPT_SWITCH configuration parameter to define the frequency at which ciphers or secret keys are renegotiated. This configuration parameter is used only for Enterprise Replication and High-Availability Data Replication.

ENCRYPT_SWITCH configuration parameter

Use the ENCRYPT_SWITCH configuration parameter to define the frequency at which ciphers or secret keys are renegotiated. This configuration parameter is used only for Enterprise Replication and High-Availability Data Replication.

The longer the secret key and encryption cipher remains in use, the more likely the encryption rules might be broken by an attacker. To avoid this, cryptologists recommend changing the secret keys on long-term connections. The default time that this renegotiation occurs is once an hour.

onconfig.std value: Not set.
values: Two positive integers separated by a comma. The first integer represents the number of minutes between cipher renegotiation. The second integer represents the number of minutes between secret key renegotiation. For example: ENCRYPT_SWITCH 2,5.
units: minutes
takes effect: For HDR: when the database server is shut down and restarted
For Enterprise Replication: when Enterprise Replication is started
