PURPOSE

TPSPRIO - set service request priority

SYNOPSIS

01 TPPRIDEF-REC.
   COPY TPPRIDEF.
01 TPSTATUS-REC.
   COPY TPSTATUS.
CALL "TPSPRIO" USING TPPRIDEF-REC TPSTATUS-REC.

DESCRIPTION

TPSPRIO sets the priority for the next request sent or forwarded. The priority set affects only the next request sent. (Priority can also be set for messages enqueued or dequeued by TPENQUEUE(3cbl) or TPDEQUEUE(3cbl) if the queued management facility is installed.) By default, the setting of PRIORITY in TPPRIDEF-REC increments or decrements a service's default priority up to a maximum of 100 or down to a minimum of 1 depending on its sign, where 100 is the highest priority. The default priority for a request is determined by the service to which the request is being sent. This default may be specified administratively (see ubbconfig(5)), or take the system default of 50. TPSPRIO has no effect on messages sent via TPCONNECT(3cbl) or TPSEND(3cbl).

Following is a list of valid settings in TPPRIDEF-REC.

TPABSOLUTE

The priority of the next request should be sent out at the absolute value of PRIORITY. The absolute value of PRIORITY must be within the range 1 and 100, inclusive, with 100 being the highest priority. Any value outside of this range causes a default value to be used.

TPRELATIVE

The priority of the next request should be sent out at the relative value of PRIORITY.

RETURN VALUES

Upon successful completion, TPSPRIO sets TP-STATUS to [TPOK].
