Parameters
parameter DEFAULTCONCURRENCY = 0;
Inherited description: DEFAULTCONCURRENCY is the default value for the concurrency formal argument
defined for %Open, %OpenId, %Delete and %DeleteId methods. It is not the default
value of the %Concurrency property of persistent classes. If the value of the actual
concurrency argument passed to any of the above methods is -1 then the formal argument value will
be set to the value of the DEFAULTCONCURRENCY parameter value defined for the class.

classmethod CollationPrompt(Prompt, Obj)
method Compact(PercentFull As %Integer = 90, ByRef MbProcessed As %Float, ByRef MbCompressed As %Float, MbToCompress As %Integer = 0, ByRef LastGlobalReference As %String = "") as %Status
Compact a global.
PercentFull - How full each data page should be, 50-100
MbProcessed - How many MB of the global was processed
MbCompressed - How many MB was it compressed to
MbToCompress - How many MB of the global to compress in this call (0=ALL)
LastGlobalReference - Last reference, "" = completed
Typical useage is as follows, which compacts the data pages to 80%full, and returns the amount of data processed, and the size it was compacted to:
s x=##Class(%GlobalEdit).Open("X",dbdirectory)
s t=x.Compact(80,.CurrSize,.NewSize)
Note that this function can be called repeatedly for the same global so that it can be done in chunks by using the last two parameters. The following example does 10MB chunks of the global at a time and accumulates and displays a status:
s x=##Class(%GlobalEdit).Open("X",dbdirectory)
s TotalCurrSize=0,TotalNewSize=0
do {
s t=x.Compact(80,.CurrSize,.NewSize,10,.LastReference)
s TotalCurrSize=TotalCurrSize+CurrSize
s TotalNewSize=TotalNewSize+NewSize

method FirstDataBlockGet() as %Integer
classmethod GetGlobalSize(Directory As %String, GlobalName As %String, ByRef Allocated As %Integer, ByRef Used As %Integer, fast As %Boolean = 0) as %Status
Get size of this global
'Allocated' - total size, in MB, of blocks allocated for the global.
'Used' - total used data, in MB, for the global.
'fast' - TRUE : faster return, it won't return the value of 'Used'.
FALSE - slower return,, it returns values for both 'Allocated' and 'Used'.
'Allocated' - total size, in MB, of blocks allocated for the global.
'Used' - total used data, in MB, for the global.
'fast' - TRUE : faster return, it won't return the value of 'Used'.
FALSE - slower return,, it returns values for both 'Allocated' and 'Used'.
classmethod GetGlobalSizeBySubscript(Directory As %String, StartingNode As %String, EndingNode As %String = "", ByRef Size As %String = 0)
Return the size of a global or range of nodes in a global.
This method will return the size of a global based on the number of database blocks the global resides in.
Parameters:
Directory - Directory where global is located.
StartNode - Staring node of global. Note that you can specify ^GLOBAL(BEGIN) to mean the start of the global. This would include ^GLOBAL itself. You can also specify ^GLOBAL("XXX"_$c(1)_"*next)" to mean start counting after global ^GLOBAL("XXX").
EndNode - End Node of global. The returned sizes do not include the EndNode. Note that you can specify ^GLOBAL(END) to mean through the end of the global. An EndNode value of null, or equal to the value of StartNode will return the size of StartNode and all children of StartNode.
Size - Maximum number of MB to count. If the size of the global exceeds this value, calculation stops, and an error is returned. If undefined or set to 0, then the entire range is counted. Be careful to reset this for multiple calls to the method.
Return Values:
The array Size returns the amount of data in both blocks and MB, for each level of the global, as well as the size of big string data, and a total. If the global does not exist, an error will be returned, and the sizes will all be set to 0. If any other error occurs, sizes will not be set.

classmethod KillRange(Directory As %String, StartingNode As %String, EndingNode As %String) as %Status
Kill a subscripted range of a single global in a single database.
This method will kill a range of globals node of a single global in a single database. The starting and ending global name must be the same. When a range is specified, the global is killed from the starting node up to but not including the ending node. The exception to this is if the starting and ending node is the same then that global is killed. The start and end nodes must not contain namespace specifications. Process private globals are not supported. Note that this method ignores all namespace specifications.
Parameters:
Directory - Location of global to kill.
StartingNode - First node of global range to kill. Note that you can specify ^GLOBAL(BEGIN) to mean the start of the global. This includes the global ^GLOBAL itself You can also specify ^GLOBAL("XXX"_$c(1)_"*next)" to mean start deleting after global ^GLOBAL("XXX").
EndingNode - Ending node of global range to kill, up to, but not including this node. Note that you can specify ^GLOBAL(END) to mean through the end of the global.
