Physical filescontain the actual data that is stored on the system, and a description of how data is to be presented to or received from a program. They contain only one record format, and one or more members. Records in database files can be externally or program-described....
NOTEWhen working with LVM, there is the physical extent size to consider. This is the size of the basic building blocks used in the LVM configuration. When working with an ext4 file system, logical extents are used. The extent size on LVM are in no way related to the extent sizes that ...
If the maximum is being used, 32 physical file names can be specified on one record format (using one PFILE keyword) or 32 physical file names can be distributed among 32 record formats; or, file names can be unevenly distributed among record formats. In any case, the maximum number of p...
Physical DFD depicts how the system will be implemented (or how the current system operates). The processes represent the programs, program modules, and manual procedures. The data stores represent the physical files and databases, manual files. It show controls for validating input data, for obta...
If you cannot find the relevant syntax group for file names and paths for your operating system, you can define your own (seeSyntax Group DefinitionandAssignment of Operating System to Syntax Group). The <FILENAME> parameter must always be set for the physical file name (seeLogical File Name...

Locate the operating systems on different physical drives to enhance component or operating system performance. Provide sufficient space to host the desired staging space limit. Note Windows 2000-based and Windows 2000 Service Pack 2-based clients must perform an authoritative restore task to...
By using thin provisioning, a storage administrator can over-commit the physical storage, often avoiding the need to purchase additional storage. For example, if ten users each request a 100GB file system for their application, the storage administrator can create what appears to be a 100GB file...
