IBM WebSphere Portal V8.5 wcm庫企業聯合組織

Question

我在AIX 7.1上有一個WebSphere Portal V8.5集羣，具有多個虛擬門戶，使用託管頁面，每個虛擬門戶擁有自己的庫和一個共享庫，供所有VP使用聯合那個圖書館給每個副總裁。

我成功創建了聯合發佈者（WAS基本門戶）和訂閱者（​​虛擬門戶）之間的聯合對，並且測試了它們之間的連接並且都很好（因爲VP在同一臺服務器上是本地的）。然而，試圖辛迪加庫內容時，它停留在排隊狀態，並在SystemOut.log我看到下面的錯誤日誌：

Answer 1

 
WCM Syndication requires HTTP Basis Authentication to be configured and working. 

then I needed to make sure that Trust Association is enabled in WAS Console under Security -> Global Security -> Web and SIP security -> Trust association. 
confirmed that the box that says Enable trust association is checked. 
also ensured the Interceptor com.ibm.portal.auth.tai.HTTPBasicAuthTAI is created and the configuration were correct. 
the cause of the error was that in the fields of urlBlackList and urlWhiteList there was use of the variable ${WpsContextRootPath} which i found out that it is not set anywhere so i change it to /wps instead and now the fields are as follow: 
urlBlackList = /wps/myportal* 
urlWhiteList = /wps/mycontenthandler* 

after Restarting the server and retry syndication - it works!. 

also you may follow the direction in this link:

but setting these parameters disabled the servlet of vieweing all items in the libraries...
