BMC Remedy Action Request System 7.1.00: Configuring

Queues
Scalability
A queue is a meeting point where remote procedure calls (RPCs) wait to be
handled by the worker threads that process the RPCs. When a queue is created, it
automatically starts the minimum number of threads specified for its thread type.
The default for this setting is 1. For more information, see “Threads” on page 27.
There are seven types of AR System queues. Each queue has an RPC program
number associated with it, as outlined in the following table.
Queue type RPC program number
Admin 390600
Alert 390601
Escalation 390603
Flashboards 390619
Fast 390620
List 390635
Private 390621–390634, 390636–390669,
390680–390694
NOTE
Administration, alert, escalation, Flashboards, fast, and list queues use a fixed RPC
program number. Private queues, however, can be configured to use any RPC
program number within the ranges of RPC program numbers reserved for private
queues.
The following sections describe the different types of queues.
References to the configuration file apply to the configuration file specific to your
system. The configuration file for Windows is ar.cfg. For UNIX ® , this file is
ar.conf.
Administration queue
The administration (admin) queue is the only AR System queue that can perform
every operation within the system. It performs all administrative restructuring
operations, guaranteeing the serialization and integrity of all restructuring
operations. This queue can have only one thread.
All servers include an admin queue, which is the default server setting. Because an
admin queue has a single thread available to handle requests, a server that has only
an admin queue (and no fast or list queues) functions as a single-threaded server.
While the admin queue handles all administrative functions, it can also perform
the functions of all other queues if no other queues are configured. If no other
queues are configured, all requests are placed in the admin queue.
