I am also facing same issue. Its keep on reloading when I tried to open any process instance. We are using 9.9 version IS and MWS. I observed below error in MWS log
2017-05-09 23:02:52 AEST (Framework:WARN) [RID:126883] - Error retrieving process instances from Integration Server.
2017-05-09 23:02:52 AEST (jsf:INFO) [RID:126883] - Analytic Engine Error. Read timed out
2017-05-09 23:02:52 AEST (jsf:INFO) [RID:126883] - java.net.SocketTimeoutException: Read timed out
I have tested all JDBC pool connections from IS admin page, all connections are working fine. Can you please help to find root cause and resolve the issue.
the information you provided is not enough for detailed analysis.
When Analytic Engine is mentioned, I assume you are using Optimize For Process.
Please check if IntegrationServer, AnalyticEngine, MWS, Monitor-Package, PRT-Package and Optimize-Package are configured correctly and that all the instance are up and running.
Please test if you can reach the ports of all these instances from each other by using i.e. Telnet commands. This is especially neccessary when they are not installed on the same box, but different boxes.
I’m using external RDBMS database for service logging in MWS. I got this error because I haven’t configured DB components into External DB.
I just configured IS and MWS database components using DB component configurator tool into External DBMS.
2)Then changed service logger destination to Database in IS Administrator under Settings → Logging
