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.
LockingThe database server uses locks, which can affect concurrency and performance. You can monitor and administer locks.
Locks with the SELECT statementThe type and duration of locks that the database server places depend on the isolation level set in the application, the database mode (logging, nonlogging, or ANSI,) and on whether the SELECT statement is within an update cursor. These locks can affect overall performance because they affect concurrency.
