Chapter 6 Administering Process Attributes : Message and Mbox Processing Configuration

Message and Mbox Processing Configuration

The following process attributes allow you to configure how iProcess Engine processes messages.

Attribute

Description

DBQD_MAX_CACHED_MESSAGES

Defines the number of messages that are cached by the DBQD process when it requests a block of messages from a database message queue.

DBQD_MAX_FIL_SESSIONS

Defines the number of concurrent threads that the DBQD process uses to process RPC requests for messages from its cache from BG or WISMBD processes.

EMPTYMBOXSLEEP

Defines how long the Mbox Daemons will “sleep” when all Mbox queues in the Mbox set are empty.

EMPTYMBOXSLEEP_INC

Defines the number of seconds to increment the EMPTYMBOXSLEEP value by when a BG or WISMBD process requests a message from an empty Mbox.

EMPTYMBOXSLEEP_MAX

Defines the maximum value (in seconds) that EMPTYMBOXSLEEP can be set to.

IQL_RETRY_COUNT

Defines how many times a failed message in a message queue is retried before being moved to the exception queue.

IQL_RETRY_DELAY

Defines the delay (in seconds) between each retry attempt for a failed message in a message queue, before the message is moved to the exception queue.

MBSET_DEQUEUE_TIMEOUT

Defines a time threshold (in milliseconds) for the duration of dequeuing a message from an Mbox set.

MBSET_READ_BG

Defines the unique identifier of the Mbox set to be used by a BG process when dequeuing messages received from a WISMBD process.

MBSET_READ_PREDICT

Defines the unique identifier of the Mbox set to be used by a BGPREDICT process when posting case changes messages to a BG process.

MBSET_READ_WIS

Defines the unique identifier of the Mbox set to be used by a WISMBD process when dequeuing messages received from a BG process.

MBSET_WRITE_BG

Defines the unique identifier of the Mbox set to be used by a process when writing to a BG process.

MBSET_WRITE_PREDICT

Defines the unique identifier of the Mbox set to be used by a BGPREDICT process when posting case changes messages to a BG process.

MBSET_WRITE_WIS

Defines the unique identifier of the Mbox set (as defined in the mbox_set table) to be used by the BG process when writing to a WISMBD process.

THRESHOLD_FAIL_TIMES_TO_REPORT_IQL_MESSAGE

Defines how many times a failed message in a message queue is retried before sending a message to the Process Sentinels.

USE_NEXT_MESSAGE_TO_DEQUEUE

Defines the ways to purge vast quantities of cases in the Oracle AQs.
