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.
Queries and the query optimizerThese topics describe query plans, explain how the database server manages query optimization, and discuss factors that you can use to influence the query plan. These topics also describe performance considerations for SPL routines, the UDR cache, and triggers.
Time costs of a queryYou can adjust a few, but not all, of the response-time effects of actions that the database server performs when processing a query.
Encrypted-value costs An encrypted value uses more storage space than the corresponding plain-text value because all of the information needed to decrypt the value except the encryption key is stored with the value.

Encrypted-value costs

An encrypted value uses more storage space than the corresponding plain-text value because all of the information needed to decrypt the value except the encryption key is stored with the value.

Most encrypted data requires approximately 33 percent more storage space than unencrypted data. Omitting the hint used with the password can reduce encryption overhead by up to 50 bytes. If you are using encrypted values, you must make sure that you have sufficient space available for the values.
