Oracle BPEL process manager rollback

-

I have a empty BPEL process that polls for AQJMS messages using a JMS adapter and then insert the received messages to the DB. Now the problem is, if there is any error w.r.t the DB insert, then it should rollback the message to the source destination i.e., my AQJMS Queue. But it is not happening. using the bpelx:rollback explicitly doesn't seem to help.


Answer:
You need to make it as one transaction. Use JCA-XA transaction. Just like in PL/SQL to make a transaction block we write it inside BEGIN ... END; in BPEL we create a JNDI of XA type (global-transaction handler) and then configure the property name 'transaction' to 'participate' for all partner links which are part of the transaction.

participate< /property>

However you need to take care of one thing, if the process is syncronous and you call rollback then it will not show up in BPEL console, since it posting to dehydration db will also be rollbacked.

How to mount a WD Book Live as NFS in OEL6U3

-
Scenario : I have a Windows 8 (Host) laptop on which I am running two OEL6U3 (Guest) machines in a Virtual Box. I want to have a shared mount between the two Linux machine which will allow me to read/write from both the machines concurrently. Its a very common scenario for a High Availability Environment. Virtual Box provides a facility of creating sharable VDI disks which can be mounted on multiple machines, but it doesn’t allow concurrent read/write access from multiple machines. If you are installing RAC database then its still achievable, because ASM will provide the feature of concurrent read/writes, but if you want to install a WebLogic cluster with High Availability the recommended approach would be to have a Shared Mount. Step to create a shared nfs mount is fairly simple. I am using a WD My Book Live, and will mount the Public folder as shared mount 1. Get the hostname/ip of the WD device. 2. On the Linux Machine 1 create the folder where you want to mount the nfs
