AVG LWAIT is the average amount of time the Consumer was waiting on a

between I/O retries as a result of the CONS RETRYDELAY parameter

setting.

%TWAIT is the percentage of the stats duration that the CONS is waiting on

locks and delaying before retrying.

AVG TWAIT is an I/O average duration that the CONS is waiting on locks

USER EXIT INFO (I/O EVENTS, TRANSACTION EVENTS) – This

section shows information relating to user exit processing. This section

is only displayed when user exit activity has occurred in the

consumer.

NUM USRXEV shows the number of USRXPROCESS calls associated with

insert, update, and delete events. This is the number of times that the

customer’s user exit code was invoked because the DBS USEREXITID

value was non-zero.

USRXEV TIME shows the amount of time the CONS has spent executing in

the USRXPROCESS and underlying code to process insert, update, and

delete events. This is the total time (wall clock) that the CONS was

executing user exit code. A large value may indicate that the user exit

code is inefficient.

%USRXEV shows the percentage of time the CONS has spent executing in

the USRXPORCESS and underlying code to process insert, update, and

delete events.

NUM USRXTR shows the number of USRXPROCESS calls associated with

“end transaction” events (i.e.,i.e., the number of times the customer’s user

exit code was invoked to process transaction abort and commit events).

USRXTR TIME shows the amount of time the CONS spent executing in

USRXPROCESS and underlying code to process “end transaction” events

(i.e.,i.e., the amount of time the customer’s user exit code spent

processing abort and commit transaction events).

%USRXTR shows the percentage of time the CONS has spent executing in

USRXPROCESS and underlying code to process “end transaction”

events.

NUM USRXEX when output, is the number of USRXEXCEPTION calls

associated with SQL target I/O error conditions.

USRXEX TIME shows the amount of time the CONS has spent executing in

the USRXEXCEPTION and underlying code to handle SQL target I/O

error conditions.

%USRXEX shows the percentage of time the CONS has spent executing in

the USRXEXCEPTION and underlying code to handle SQL target I/O

error conditions.
