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.
Performance GuideThe HCL OneDB™ Performance Guide describes how to configure and operate your HCL OneDB™ database server to improve overall system throughput and to improve the performance of SQL queries.
Effect of configuration on I/O activityThe configuration of your database server affects I/O activity.
Background I/O activitiesBackground I/O activities do not service SQL requests directly. Many of these activities are essential to maintain database consistency and other aspects of database server operation. However, they create overhead in the CPU and take up I/O bandwidth.
Configuration parameters that affect loggingThe LOGBUFF, PHYSBUFF, LOGFILES, LOGSIZE, DYNAMIC_LOGS, AUTO_LLOG, LTXHWM, LTXEHWM, SESSION_LIMIT_LOGSPACE, SESSION_LIMIT_TXN_TIME, and TEMPTAB_NOLOG configuration parameters affect logging. The LOGBUFF, PHYSBUFF, LOGFILES, LOGSIZE, DYNAMIC_LOGS, LTXHWM, LTXEHWM, and TEMPTAB_NOLOG configuration parameters affect logging.
TEMPTAB_NOLOG and its effect on loggingThe TEMPTAB_NOLOG configuration parameter allows you to disable logging on temporary tables. You can do this to improve performance and to prevent OneDB from transferring temporary tables when using High-Availability Data Replication (HDR).

TEMPTAB_NOLOG and its effect on logging

The TEMPTAB_NOLOG configuration parameter allows you to disable logging on temporary tables. You can do this to improve performance and to prevent OneDB from transferring temporary tables when using High-Availability Data Replication (HDR).

To disable logging on temporary tables, set the TEMPTAB_NOLOG configuration parameter to 1.

To enable logging on temporary tables for primary server and to disable logging on temporary tables for secondary servers(HDR, RSS and SDS), set the TEMPTAB_NOLOG configuration parameter to 2.
