[OO Support Tip] Flow validation fails
Under certain circumstances flow validation in Studio fails and also the Remote Action Services (RASes) configured show as UNAVAILABLE. This can happen even when the RAS definitions are valid, pointing to the correct host.
This shows in the Studio.log with entries similar to this:
ERROR [SwingWorker-pool-3-thread-3] (14:26:00,148) com.iconclude.dharma.model.operations.WebOperation - retrieved <null> signature for WebOperation: 'ovcm-oo.jar'::'com/hp/ovcm/oo/SetPolicy.class'
Two possible reasons for this have been uncovered:
1) The RAS definition points to localhost instead of a hostname. This causes Studio to try to connect to localhost:9004. For standalone Studio installations, localhost will not be listening on port 9004 as RAS is not running on the same server. The solution is to change localhost to the Fully Qualified Domain Name (FQDN) of the RAS server, i.e. its hostname.
2) The RAS definition points to a hostname with inconsistent Domain Name Service (DNS) records. For example, the reverse DNS entry for the RAS's IP points to a different hostname to the one used in the RAS definition. In order to fix this an entry needs to be added in /etc/hosts (on Linux) or %WINNT%\system32\drivers\etc\hosts (on Windows) in the format of:
IP FQDN hostname
e.g. 22.214.171.124 host.domain.tld host
