Could not create/access the TopLink Session.
This session is used to connect to the datastore. [Caused by: Io exception: The Network Adapter could not establish the connection]

You may need to configure the connection settings in the deployment descriptor (i.e. $J2EE_HOME/application-deployments/default/DbAdapter/oc4j-ra.xml) and restart the server. Caused by Exception [TOPLINK-4002] (Oracle TopLink - 10g Release 3 (10.1.3.1.0) (Build 061004)): oracle.toplink.exceptions.DatabaseException

原因:
ha因为要引用host文件,host文件的内容有问题,导致无法连接。host更新之后就好了。

原因:启动顺序出现问题
正常启动顺序为
1)启动eai平台之前,需要把定时器的状态置为0,不让所有的timer启动
2)启动bpel
3)启动weblogic(OSB)
4)从bpel控制台清理session缓存
5)然后再启动timer
我们把第2步弄完之后,直接到第4步了,启动weblogic之后又有新的缓存,所以无法连接数据库。
