Groups of jobs are managed using queues. Queues distribute jobs to process servers, where the jobs actually run.

You can use queues to limit the number of jobs that can run simultaneously, distribute workload across multiple systems and provide failover facilities. One queue can be attached to multiple process servers, in which case SAP CPS decides which process server to run the job at when the job starts. One process server can be attached to multiple queues, in which case it can run jobs from any of those queues.

Note Note

SAP recommends you to specify a time zone on a queue, especially when you tie a time window to it to make sure the correct time is used.

Finding Queues

You can search for queues using filters and the Search Queues box on the Queues tab. This box is known as the intelliSearch box and located under your username on the top right-hand side of the user interface. Filters allow you to specify a list of objects with static criteria. IntelliSearch allows you to specify complex queries in a simple way using prefixes. Prefixes are used to specify which property you are searching in and have short and long syntaxes. For example, if you want to display all queues with the term production in the comment, you would use the search criteria as follows:

c:production

You can search more than one property, as follows:

c:production n:B1I

Note Note

No spaces should be entered before or after the colon (:).

End of the note.

See the Advanced Object Search for more information.

The following table illustrates the available prefixes for queues:

Prefixes

Description

n, name

searches the name property

c, com, comment

searches the comment property

d, desc, description

searches the description property

a, app, application

searches the application property
Deleting Queues

You can only delete queues when no other objects relate to them. For example, if there are jobs that have run in the queue, the queue cannot be deleted until all jobs that ran in it have been deleted. You can see all jobs that relate to the queue in Related Objects in the lower detail pane and on the show page.

The table in related objects contains three columns:

  • Type - the type of object with a link to it

  • Related Object - the name of the object with a link to it

  • Used As - objects can sometimes be used in different roles
