T_EVENT_SERVICE Class Definition
Overview
The T_EVENT_SERVICE class represents a set of subscriptions registered with the EventBroker 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, 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 regular expression 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() call is transactional, include the TA_SERVICENAME service call in the client's transaction.
