    Posted 11-23-2017 11:19 AM

    What is the recommended sequence to restart the CA Clarity services:

    -Admin server

    -Beacon server

    -BG server

    -App server

     

     

    We noticed that some processes are getting hanged up and a restart of the services is fixing the problem. what is the order that we should restart the services?

    Thanks.

    Restarting the services masks the problem and doesn't provide any root cause. if your process are hanging see if you have huge number of instances which are not deleted and if you are doing excessive logging then your BPM_ERRORS tables would be flooded and cleaning process instances cleans the record in BPM_ERRORS and few other BPM* tables too.

     

    Also please let us know what version of PPM you are in? Also look at if you have adequate JVM allocation an you can refer to our documentation where we have given white papers https://docops.ca.com/ca-ppm/15-3/en/reference/oracle-and-ms-sql-database-performance-whitepapers/ 

     

    If you still face issue please raise a support case and we will work with you and get it resolved.

    While cleaning up the initiated processes ( i had over 200 pages) I lost my delete button. It's not at the end of the pages anymore. It was there and now it's not. Where can you control this action button?

    You dont need to delete manually, you can run Delete Process Instance Job and it will delete for you.

    What might be the reason for the button disappearing and how would you get it back?

    sorry that was a screen resolution issue. hiding these msg at the bottom. Deleting initiated instances of the processes is not an issue.

    Hi Georges. 

       Do you do any scripted restarts on a cadence today? As an On-Premise Windows infrastructure admin, I can sing the praises of scheduled tasks. There's just too much going on in your infrastructure that you will never know about and will never be in any vendor's test infrastructure & documentation, nor may ever be resolved by a support case.

     

       I do a weekly scheduled restart of all services on all servers (service stop all, service start all), and run a service start all every 5 minutes. I implemented this over 6 years ago and this makes all kinds of these kinds of weirdnesses just go away. I highly recommend it.

     

       By all means open a support ticket and see if CA can ID something amiss with your configuration - but if not, take action to set yourself up for success in your organization's infrastructure, which is outside of CA's ability to influence.

    FYI - Our organization does monthly server patching, where my servers may be restarted. Historically, this hasn't been an issue, but twice now in the last 4 months the app hasn't come back up properly. A simple app restart fixes this. Something has changed and its not my CA PPM instance. I will not open a CA Support ticket yet - it's my job to own it. I will start by scripting an app re-start an hour after their server patching window to see if this makes this gremlin go away. If not, then I may go down the support path.

    Thank you for your interactions. But no one has answered my original question yet. What is the recommended sequence for starting up the services?

    Unsure if there is one. We've been doing 'Stop All' 'Start All' for years now with no troubles.
