Status: Verified
FACT(s) (Environment):
Apptivity
SYMPTOM(s):
Error appears in the browser with an HTML project if the agent doesn't come back
from preparing the session.
Error 503 Service Unavailable, No agents are AVAILABLE.
CAUSE:
The agent is responsible for connecting to the database. If the ODBC
datasource is not available (for example, deleted, renamed or not accessible for the current user) you will get the error 503.
FIX:
To correct the error check if the ODBC Data source (you will find the name under the properties of the Data Connection) is available for the current user and use the ODBC administrator to correct the problem.
Another possible reason of the error is if the agent doesn't find the connection to the Distribution Manager. That happens if the Distribution Manager is not running or the Distribution Manager's host or port properties don't fit the apptivity.naming.host and apptivity.naming.port property inside the <project>.properties file.
Working example:
dmanager.properties:
apptivity.dmanager.host=pcrwe2
<project>.properties:
apptivity.naming.host=pcrwe2
apptivity.naming.port=2804
Error 503 also appears if the Component Manager was not found.
