CIM_DatabaseSegmentSettingData Superclass: CIM_ScopedSettingData
This class defines the attributes that affect the growth of a DatabaseSegment. The attributes are tied to the DatabaseSegment through an ElementSettingData association.
This class can also be used to specify the default settings for all DatabaseSegment instances that are created within a CommonDatabase through an ElementSettingData association to the CommonDatabase. Processes that create new instances of DatabaseSegment and the associated setting data should check for a DatabaseSegmentSettingData instance that is associated with the CommonDatabase and should create a new instance of DatabaseSegmentSettingData that is specific to the DatabaseSegment only if the default settings need to be overridden or frozen for the specific DatabaseSegment instance.
Qualifiers:Version ( "2.8.0" )
Parameters (local in grey)
MinValue ( 0 )
Write
ModelCorrespondence { "CIM_DatabaseSegmentSettingData.NextExtentSize" }
uint16 PercentIncrease ;
The percentage by which the next incremental extent will grow over the previously allocated size of all extents for the segment. A PercentIncrease of 0 indicates that all incremental extents will be the same size, as specified by NextExtentSize. This value is ignored and should be set to 0 if NextExtentSize has a value other than 0.
Write
Units ( "Bytes" )
uint64 InitialExtentSize ;
The size, in bytes, of the first extent to be allocated when a database segment is created.
Write
uint64 MinimumExtents ;
The total number of extents to be allocated when the database segment is created. This setting allows for a large initial segment allocation at creation time, even if contiguous space is not available.
Write
uint32 NumberOfFreeLists ;
A freelist is a list of the free blocks that are associated with a database segment. The freelist is used to determine which segments are eligible for accepting data when a new insert or update request is processed. The NumberOfFreeLists setting identifies the number of freelists that are defined for the database segment. This value is typically set to the expected number of concurrent inserts for the segment.
MinValue ( 0 )
Write
Units ( "Bytes" )
ModelCorrespondence { "CIM_DatabaseSegmentSettingData.PercentIncrease" }
uint64 NextExtentSize ;
The size, in bytes, to be allocated for the next incremental extent for the segment. A NextExtentSize of 0 indicates that the size of incremental extents will be determined based on the value of PercentIncrease.
Write
uint64 MaximumExtents ;
The upper limit on the number of extents that can be allocated for the segment.
Required
Override ( "ElementName" )
string ElementName ;
The user-friendly name for this instance of SettingData. In addition, the user-friendly name can be used as an index property for a search or query. (Note: The name does not have to be unique within a namespace.)
Key
string InstanceID ;
Within the scope of the instantiating Namespace, InstanceID opaquely and uniquely identifies an instance of this class. To ensure uniqueness within the NameSpace, the value of InstanceID should be constructed using the following 'preferred' algorithm:
<OrgID>:<LocalID>
Where <OrgID> and <LocalID> are separated by a colon (:), and where <OrgID> must include a copyrighted, trademarked, or otherwise unique name that is owned by the business entity that is creating or defining the InstanceID or that is a registered ID assigned to the business entity by a recognized global authority. (This requirement is similar to the <Schema Name>_<Class Name> structure of Schema class names.) In addition, to ensure uniqueness, <OrgID> must not contain a colon (:). When using this algorithm, the first colon to appear in InstanceID must appear between <OrgID> and <LocalID>.
<LocalID> is chosen by the business entity and should not be reused to identify different underlying (real-world) elements. If the above 'preferred' algorithm is not used, the defining entity must assure that the resulting InstanceID is not reused across any InstanceIDs produced by this or other providers for the NameSpace of this instance.
For DMTF-defined instances, the 'preferred' algorithm must be used with the <OrgID> set to CIM.
MaxLen ( 64 )
string Caption ;
The Caption property is a short textual description (one- line string) of the object.
string Description ;
The Description property provides a textual description of the object.
