T_EVENT_SERVICE CLASS DEFINITION

Overview

The T_EVENT_SERVICE class represents a set of subscriptions registered with the Event Broker for service-based notification. When an event is detected, it is compared to each T_EVENT_SERVICE object. If the event name matches the value in TA_EVENT_EXPR and the optional filter rule is true, then the event buffer is sent to the specified BEA TUXEDO service routine.

Attribute Semantics

TA_EVENT_EXPR: string[1...255]

Event pattern expression. This expression, in recomp(3) format, controls which event names match this subscription.

TA_EVENT_FILTER: string[1...255]

Event filter expression. This expression, if present, is evaluated with respect to the posted buffer's contents. It must evaluate to TRUE or this subscription is not matched.

TA_EVENT_FILTER_BINARY: carray[1...64000]

Event filter expression, in binary (carray) format. Same as TA_EVENT_FILTER, but may contain arbitrary binary data. Only one of TA_EVENT_FILTER or TA_EVENT_FILTER_BINARY may be specified.

TA_STATE:

GET: ACTive

A GET operation will retrieve configuration information for the matching T_EVENT_SERVICE object(s).

SET: {NEW|INValid}

A SET operation will update configuration information for the T_EVENT_SERVICE object. The following states indicate the meaning of a TA_STATE set in a SET request. States not listed may not be set.

NEW	Create T_EVENT_SERVICE object. Successful return leaves the object in the ACTive state.
INValid	Delete T_EVENT_SERVICE object. Successful return leaves the object in the INValid state.

TA_SERVICENAME: string[1...15]

Call this BEA TUXEDO service when a matching event is detected.

TA_EVENT_PERSIST: short

If non-zero, do not cancel this subscription if the TA_SERVICENAME service is no longer available.

TA_EVENT_TRAN: short

If non-zero and the client's tppost(3) call is transactional, include the TA_SERVICENAME service call in the client's transaction.
