databasekonfigurasjoner

Databasekonfig, a term sometimes used to describe database configuration, refers to the collection of settings that determine how a database management system (DBMS) allocates resources, enforces security, handles connections, and manages data processing. Configuration can be applied at startup or modified at runtime, depending on the system, workload, and operational requirements.

A typical configuration covers server-level settings (memory and I/O limits, connection limits, logging), database-level options (default storage, language, collation), and security policies (authentication methods, encryption, access controls). It may also govern replication, high availability, backup behavior, and maintenance tasks. Environment-specific configurations support separating development, testing, and production settings to minimize risk.

Configuration is often stored in text files, JSON, YAML, or in a management interface. Examples include PostgreSQL's postgresql.conf and pg_hba.conf, MySQL's my.cnf, Oracle and Oracle XE spfile/pfile, and SQL Server's configuration manager. Some systems allow dynamic changes via SQL commands, REST APIs, or CLI tools without a restart.

Common parameters include maximum connections, memory allocations (shared_buffers, work_mem), checkpoint and write-ahead logging (WAL) settings, logging verbosity, cache sizes, and timeouts. Proper tuning depends on workload, hardware, and monitoring data, and should follow a plan that includes baseline measurements, staged changes, and rollback mechanisms.

Best practices emphasize versioned configurations, minimal privilege, secure handling of credentials, and environment-specific templates. Changes should be tested in a non-production environment, documented, and backed by monitoring to detect regressions in performance or stability.
