# 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 remain idle 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.
