I was trying to find a way to change ALDSP end points programmatically -- without having to go into the ALDSP console and manually retarget the physical stores. I was hoping for a way to do this similar to the work I was doing with WebLogic JDBC pools and JMX. Alas, there is no equivalent. BEA did point out, however, the information is stored the XML configuration file:
admindomain/liquiddata/myaldspappLDConfig.xml
The file is read when the application is deployed. So it is at least possible to make these changes, though it involves some XML hackery.
