Config.WorkQueues

persistent class Config.WorkQueues extends %Library.Persistent, Config.CommonMultipleMethods, Config.CommonProperties, %SYSTEM.Help

SQL Table Name: Config.WorkQueues

This class allows you to modify and view the [WorkQueues] section of the CPF file through programatic APIs. While properties are usually modified through the System Management portal, there may be some occasion where modifying them through the API's is best for your system. In all the Config methods, if you do not specify the CPFFile parameter, the currently active CPF file is used. If you wish to modify a CPF file which is not the currently active one, then specify the CPFFile you wish to modify in the method call.
The Flags parameter does not normally need to be specified; the defaults are usually sufficient for most cases.
You can use either the provided API's (Create/Get/Modify/Delete) to modify the properties by passing in the correct parameters, or use Object sytax to open and directly manipulate the config objects (Open() and Exists()). Most objects created here need only to specify the Name of the object, and 1 or 2 properties since the the defaults are what are commonly used for most cases.

EXAMPLE:

; Use class methods to create an instance
%SYS>s Name="TEST"
%SYS>s Properties("MaxActiveWorkers")=8
%SYS>s Status=##Class(Config.WorkQueues).Create(Name,.Properties)
%SYS>i 'Status w !,"Error="_$SYSTEM.Status.GetErrorText(Status)
; Use class methods to modify properties
%SYS>s Status=##Class(Config.WorkQueues).Get(Name,.Properties)
%SYS>i 'Status w !,"Error="_$SYSTEM.Status.GetErrorText(Status)
%SYS>zw Properties
Properties("DefaultWorkers")=0
Properties("MaxWorkers")=0
Properties("MaxActiveWorkers")=8
%SYS>s Properties("MaxActiveWorkers")=4
%SYS>s Status=##Class(Config.WorkQueues).Modify(Name,.Properties)
%SYS>i 'Status w !,"Error="_$SYSTEM.Status.GetErrorText(Status)
; Now use Objects to modify properties
%SYS>s Obj=##Class(Config.WorkQueues).Open(Name)
; We could have used i ##Class(Config.WorkQueues).Exists(Name,.Obj) instead of Open()
%SYS>w Obj.MaxActiveWorkers
4
%SYS>s Obj.MaxWorkers=2
%SYS>s Status=Obj.%Save()
%SYS>i 'Status w !,"Error="_$SYSTEM.Status.GetErrorText(Status)
; Now delete the object we just created
%SYS>s Status=##Class(Config.WorkQueues).Delete(Name)
%SYS>i 'Status w !,"Error="_$SYSTEM.Status.GetErrorText(Status)

Property Inventory

• DefaultWorkers
• MaxActiveWorkers
• MaxWorkers

Method Inventory

• IsSystemWorkQueue()
• MaxWorkersAvailable()

Parameters

parameter CAPITALNAME = 0;

WorkQueue name is not capitalized.

Properties

property DefaultWorkers as %Integer (MINVAL = 0) [ InitialExpression = 0 , Required ];

When a work group in this category is created and no worker job count is specified this is the default number of worker jobs we will assign to the group. 0 = Dynamic.

Property methods: DefaultWorkersDisplayToLogical(), DefaultWorkersGet(), DefaultWorkersGetStored(), DefaultWorkersIsValid(), DefaultWorkersLogicalToDisplay(), DefaultWorkersNormalize(), DefaultWorkersSet(), DefaultWorkersXSDToLogical()

property MaxActiveWorkers as %Integer (MINVAL = 0) [ InitialExpression = 0 , Required ];

Maximum number of active worker jobs we will keep in the pool of jobs servicing requests in this category. Idle jobs are detected and new jobs are started automatically to keep the maximum active job number around this limit. 0 = Dynamic, -1 = unlimited.

Property methods: MaxActiveWorkersDisplayToLogical(), MaxActiveWorkersGet(), MaxActiveWorkersGetStored(), MaxActiveWorkersIsValid(), MaxActiveWorkersLogicalToDisplay(), MaxActiveWorkersNormalize(), MaxActiveWorkersSet(), MaxActiveWorkersXSDToLogical()

property MaxWorkers as %Integer (MINVAL = 0) [ InitialExpression = 0 , Required ];

When a work group in this category is created specifying the number of worker jobs wanted and the number requested is greater than this limit then we will use this limit value instead. 0 = Dynamic

Property methods: MaxWorkersAvailable(), MaxWorkersDisplayToLogical(), MaxWorkersGet(), MaxWorkersGetStored(), MaxWorkersIsValid(), MaxWorkersLogicalToDisplay(), MaxWorkersNormalize(), MaxWorkersSet(), MaxWorkersXSDToLogical()

Methods

classmethod IsSystemWorkQueue(Name As %String) as %Boolean

Returns whether

classmethod MaxWorkersAvailable() as %Integer

Maximum Number of Queue Manager Workers for the system

Queries

query List(Names As %String = "*", CPFFile As %String = "", Flags As %Integer = 0, Format As %Integer = 0)

Selects Name As %String, MaxActiveWorkers As %Integer, DefaultWorkers As %Integer, MaxWorkers As %Integer

List WorkQueues in a CPF file.

Parameters:
Names - Comma separated list of WorkQueue names
"*" - All records match

"String*" - Any record starting with "String"
"String,String1*,String2" - Any record matching one of these elements, or starting with "String1"
CPFFile - Name of the CPF file to use. A null string means use the active CPF file.
Flags - Currently ignored.
Format
0 - Standard report list format
1 - ^CONFIG global format
2 - CPF file format format
Note: This query may change in future versions
