Problem Summary:
The Database connections are not being released by the adapter even when the service has ended. All the connection are shown as busy connections although the service threads running are only 1. From the operating system process state (ps -eaf|grep oracle) we observed that all the 50 connections are being used. The webMethods service that uses those connections is called via HTTPS (We are using LoadRunner to call HTTPS service. Only 10 request/minutes. In fact we tried with single request). And the service ends properly without any errors. And from webMethods web interface we can see that there is only 1 service thread running. But still the database connection remains active.
The same service is running on a different machine with identical configuration and there is no such problem there.
The adapter is configured as “NO_TRANSACTION” , we also tried to set it as “LOCAL_TRANSACTION” and modified the service to use explicit transaction. But then we get “Transaction is Active” error in the error log.
I have searched thoroughly on advantage forums/knowledge base , but did not find anything. On 18th May goethals posted this message which is related. http://advantage.webmethods.com/cgi-bin/advantage/main.jsp?w=0&targChanId;d=-536880993&tid=161061;18322
