Hi Shiva,

Thanks for posting on PSC.

In your flow, are you attempting to access PDN? I have reviewed the logs and found that your flow is expecting to access pdn.pega.com. Log entry: "Caught unhandled exception: java.lang.RuntimeException: java.net.UnknownHostException: pdn.pega.com".

The issue occurs when the Designer Studio portal attempts to access the PDN, to display a sidebar on the right side containing the latest PDN news or from any other explicit access from the application.

There is a Dynamic System Setting "AllowAccessToExternalSystem" which defaults to "true" which determines, whether the PDN access attempts are made or not.  

Setting this to "false"  removes the exceptions.  

Hope it helps you in solving the problem at your end, kindly mark as answered if it does.

Regards,

Asif

Hi,

Thanks for quick response.

I tried  Dynamic System Setting "AllowAccessToExternalSystem" set as false, cleared cache, restarted and tried. Not worked. Please find the log file and tracer.

Hi Shiva,

The logs you shared are not complete logs. They are filtered ones. Please click on the options button and remove the username filter and send the complete log trace, else download it and send the complete file. You can download it from the screen where you have opened it.

PDN exception might be due to the home page in designer studio accessing PDN. You can ignore it as of now.

Hi,

i have seen the tracer screen shots and issue is not related to pdn feeds. PDN feeds will not cause any exception on work object creation. Issue is there  in Work-Cover-.Add activity while creating work object. Share the complete logs you find PegaRULES-2017-Dec-25 file  in your pega installation folder eg:- C:\Pegainstall \tomcat\work\Catalina\localhost\prweb

Thanks,

Deva

So below exception you get while running the flow

Are you acquiring lock on any instance , could you provide the screenshot of add activity as something gone wrong in step:7 .

Hi Shiva,

Here issue is Step page value passed as null.

So check if the value is null or not and then call the method .

Thanks,

Arun

I totally agree with @DevarajuluP1151 you will see PDN feeds exception  when the system is not online or the PDN server have some issues  .

So share us the logs from the tomcat directory or check if the file path in  prlogging.xml is changed for below appender .

<appender name="PEGA" class="com.pega.pegarules.priv.util.DailySizeRollingFileAppenderPega">

 <param name="FileNamePattern" value="{web.tmpdir}/PegaRULES-'yyyy-MMM-dd'.log'"/> .

Thanks,

Arun
