RPC Server

hi everyone,

when i want to open deltav explorer, it shows me a notification that write: "the RPC server is unavailable"!

what shall i do to run the software? please help me...

  • This means that the applications connection to the database has been lost
    * Try reopening the application.* Try rebooting the computer
    * Try the other things suggested on this forum
  • Hi,
    Well as Chris has mentioned, RPC server unavailable is an indication that the connection to the database is lost. This could be due to many reasons and you will have to try and resolve this issue by trial and error:

    1. If this is just due to some windows issue, it might be resolved by reopening application, rebooting computer etc.
    2. You could try shutting down the database and restarting: Start>> Run>> dbadmin (Database Administrator)>> Shut down deltav server>>> after it is stopped then reconnect
    3. If all of the basic troubleshooting doesn't resolve, try running workstation configuraiton (make sure to check Preserve network definition check box to maintain the details about the network communication such as operator stations )
    4. Worst case could be the database has been corrupted and create a new database and import the new database.
    5. Last option would be re-installation of DeltaV

    Please try options 1 and 2 as they are basic and doesn't involve any risk.
    Try options 3, 4, and 5 in order as they involve efforts in increasing order and should be exercised as a last resort.

    Thanks.

    Thanks Purnendu,
    it was not due to windows issue. i've done restart windows for several many times. also i couldn't shutdown deltav server by database administrator. a box displays a notification to me "the RPC Server is unavailable". and for creating new database by deltav administrator, it opened a new display and want to enter a new deltav database name, but no entrance box!
    unfortunately i didn't get any back up of my database and it was corrupted. so i couldn't import that on its new!
    do you have any method to resolve corrupted database and restore it?

    Hi Mohsen,

    In this case, I have to say that we are in the trial/error territory. From your response I could descern that you are able to access database administration window and it is also showing some errors.

    Still, I would suggest you to try out following options:

    1. If nothing else is working, then try following:
    Start>> cmd (command prompt) > type: c:\Users\Administrator> net stop deltav
    this will stop the deltav services. After the processing has been completed,
    Start>> cmd (command prompt) > type: c:\Users\Administrator> net start deltav

    Now attempt to open the explorer.

    2. Another option is to re-register the application by:
    Start>> cmd (command prompt)> type: c:\Users\Administrator> regall /register

    This will register all DeltaV components with windows again and then attempt to open the explorer.

    3. Verify that RPC service is started in the start>>RUN>>services.msc along with DeltaV service.

    4. For backing up the database, try using Backup & Restore option from the Database Administration. It backs up the database (not in fhx). If this is successful try to create a new database/ copy database and restore the backed up database to the one now created and set as active.

    5. Run workstation configuration.

    Also for future references, I would like to suggest you to take regular backups of the database.

    Thanks.
