oracle - WCF Application Design -


i starting development of simple wcf application queries data oracle 11g db table , enqueues message websphere mq 5.3. not sure of best way design application.

should use oracle trigger notify wcf when change made table or should use wcf continually poll db table changes?

also, how can wcf communicate websphere mq 5.3? i've researched enough see newer version of websphere mq 7.1 comes custom channel wcf don't know how wcf work 5.3.

i've been told don't use microsoft biztalk or oracle database change notification(odbn). should recommend supervisor upgrade websphere mq 7.1 , use biztalk or odbn?

i new using wcf, oracle, , websphere mq , unsure direction take. links or resources me figure out appreciated.

mq 5.3 out of support. not recommended use out of support product. found wcf support not available in mq v5.3. wcf support available mq v7.0.1. have upgrade @ least mq v7.0.1.

mq wcf provides custom channel using web services can hosted on mq , clients can call web services using custom channel.

if intention use mq wcf putting messages queue , not develop web service, better @ either mq .net classes or xms .net classes. mq .net classes provide oo api messaging mq queue/topic whereas xms .net provides jms api.

my 2 cents on other part: better receive notifications oracle db when change happens polling. there way in oracle register callback or listener gets called when change occurs table.
