Areas - Runtime-Dependent Area Properties
The same points apply to runtime-dependent properties of an area as to
dynamic area properties , with
the difference that they can be given default values by a developer and
can also be changed without a developer key, by administrators for
example, during Customizing or operation.
With client-dependent areas , the
runtime-dependent area properties can be set individually for each
client. The default values are used if no separate runtime-dependent
area properties are specified for a client.
Area Build Type
This property specifies when area
instance versions of the area should be built automatically using the
area constructor that is implemented in the
area constructor class . Possible
values are:
No Autostart
Area instance versions are not built automatically. The basic property
automatic area building
must not be activated with this setting.
Autostart for Read Request
A new area instance version is built automatically if there is a read
access and no active area instance version is available. The basic
property automatic area building
must be activated.
Autostart for Read Request and Every Invalidation
Automatic area building as is the case with
Autostart for Read
Request , and additionally with read access of a displaced or expired
area instance version. The basic property
automatic area building
must be activated.
Size of an Area Instance Version
This property determines the maximum permitted size of an individual
area instance version . Possible
values are:
No limit
No restriction on size.
Maximum ... KB
Size restriction up to a specified number of kilobytes . If the
maximum size is less than the current size of an area instance version
during operation, read access is still possible, but change access is
not. Change access is not possible again until the size of the current
area instance version falls below the maximum size.
Number of Versions of an Area Instance
This property specifies the maximum number of versions of an
area instance . Possible values are:
No limit
No restriction.
Maximum ...
Restriction up to the number you specify. If you want to specify a
number, the fixed area property
area instance versioning must have been activated. If the maximum
number of area instance versions during operation is less than the
current number of area instance versions, no versions can be deleted
although new versions can be created once the number is below the
maximum number permitted.
Lifetime of an Area Instance
This property controls the lifetime of
area instance versions .
Possible values are:
No specification
The lifetime is not restricted.
Expires after ... minutes
If a number is specified here, an area instance version becomes obsolete
this number of minutes after a change lock is released.
Refresh after ... minutes
If a number is specified here, the area constructor in the
constructor class is called this
number of minutes after a change lock is released. The prerequisite for
this is that the basic property
automatic area building is activated.
Without read access ... minutes
If a number is specified here, an area instance version becomes obsolete
this number of minutes after a read or change lock is released.
