iql_queues

The iql_queues table defines each message queue that is available on this iProcess Engine node.

Structure

The iql_queues table has the following structure:

TABLE iql_tables (
	queue_id	  number(5)		NOT NULL,
	queue_name	  varchar2(24)		NOT NULL,
	queue_type	  number(2)		NOT NULL,
	queue_phys_descr  varchar2(100)		NOT NULL)

Column	Description
`queue_id`	Unique identifier for this message queue.
`queue_name`	Name of this message queue.
`queue_type`	Message type used by this message queue. This value is always `1`, for local messages.
`queue_phys_descr`	ID of the Oracle AQ queue that is used to hold this message queue. See: Format of the Oracle AQ QueueID for a description of the format used for this value. Oracle AQ Queue Tables and Queues for more information about the required structure of AQ queue tables and queues, and how to create them.

Format of the Oracle AQ QueueID

The ID of the Oracle AQ queue that is used to hold this message queue (in the queue_phys_descr column) is specified using the following format:

0001:[instance]:queue_table:queue

where:

• 0001 indicates that the remainder of the string uses Oracle AQ format.

• instance is the Oracle Service Name of the Oracle instance that holds the AQ queue. If this is blank, the default local instance is assumed.

• queue_table is the name of the AQ queue table that holds the AQ queue.

• queue is the name of the AQ queue used to hold this message queue.

For example, the entry:

0001::bgmboxtable1:bgmboxqueue1

describes the AQ queue called bgmboxqueue1 contained in queue table bgmboxtable1 on the default Oracle instance.

Default Message Queues and AQ Tables

When the iProcess Engine is installed, the init2Kora.sql (on UNIX, or on Windows init2Kora_tok.sql) script creates the following default set of message queues and AQ queue tables required by the system.

Queue Name	Oracle AQ Queue ID
`BGMBOX1`	`0001::bgmboxtable1:bgmboxqueue1`
`BGMBOX2`	`0001::bgmboxtable2:bgmboxqueue2`
`WISMBOX1`	`0001::wismboxtable1:wismboxqueue1`
`WISMBOX2`	`0001::wismboxtable2:wismboxqueue2`
`PREDICTMBOX1`	`0001::predictmboxtable1:predictmboxqueue1`
`PREDICTMBOX2`	`0001::predictmboxtable2:predictmboxqueue2`

Table Activity

The iql_queues table contains one row for each message queue that is available on this node.

Rows are added, updated and deleted in the following situations.

A row is...	When...
added	a new message queue is added to the node, either at installation or by using the `SWDIR\util\swadm` utility.
updated	a message queue’s details are updated, using the `SWDIR\util\swadm` utility.
deleted	a message queue is deleted from the node, using the `SWDIR\util\swadm` utility.
