Disk, memory, and process management
- Virtual processors and threads
These topics describe virtual processors, explain how threads run within the virtual processors, and explain how the database server uses virtual processors and threads to improve performance. - Manage virtual processors
These topics describe how to set the configuration parameters that affect database server virtual processors, and how to start and stop virtual processors. - Shared memory
These topics describe the content of database server shared memory, the factors that determine the sizes of shared-memory areas, and how data moves into and out of shared memory. - Manage shared memory
- Data storage
The database server uses physical units of storage to allocate disk space. It stores data in logical units. Unlike the logical units of storage whose size fluctuates, each of the physical units has a fixed or assigned size that is determined by the disk architecture. - Manage disk space
You can use several utilities and tools to manage disk spaces and the data that the database server controls. - Moving data with external tables
You can use external tables to load and unload database data. - Storage space encryption
You can encrypt storage spaces (dbspaces, blobspaces and smart blobspaces) with Informix Dynamic Server. The data in encrypted storage spaces is unintelligible without the encryption key. Encrypting storage spaces is an effective way to protect sensitive information that is stored on disk.
