The GA version of the Workload Automation (WA) Agent Manager was installed, connected it to the latest version of the CA-7 Rest API (r12.1.05 Build 1111) and have defined two instances of CA-7 that are running in our test environment.
When adding the instances to the WA Agent Manager both are showing the default instance.
When going direct to the Rest API and list the Agents it correctly shows all the instance.
When defining the second CA 7 instance to WAM, an instance name must be specified to avoid using the DEFAULT_INSTANCE.
