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 memory utilizationThe combination of operating-system and HCL OneDB™ configuration parameters can affect memory utilization.
Data-replication buffers and memory utilizationData replication requires two instances of the database server, a primary one and a secondary one, running on two computers. If you implement data replication for your database server, the database server holds logical-log records in the data-replication buffer before it sends them to the secondary database server.

Data-replication buffers and memory utilization

Data replication requires two instances of the database server, a primary one and a secondary one, running on two computers. If you implement data replication for your database server, the database server holds logical-log records in the data-replication buffer before it sends them to the secondary database server.

The data-replication buffer is always the same size as the logical-log buffer.
