    Unanswered: Encount error DB21016E when attach to an other instance

    hi,All
    when i change instance from the default i get the error: DB21016E The Command Line Processor encountered a system error while sending
    the command to the backend process.
    i search for DB21016E in the IBM Message Reference and get the information like these:
    Explanation:
    One of the following could have happened:
    The backend process was abnormally terminated.
    A system error occurred when reading from or writing to the back-end process queues.
    A system error occurred when reading from the front-end process output queue.
    User Response:
    Resubmit the command. If the error occurs again, get help from your system administrator.
    i cann't get the real help from the message.

    $ uname
    SunOS
    $ echo $DB2INSTANCE
    db2inst1
    $ DB2INSTANCE=db2inst2
    $ export DB2INSTANCE
    $ db2 get instance
    DB21016E The Command Line Processor encountered a system error while sending
    the command to the backend process.

    Best regard.

    backend

    this will be related to the system setting
    there is a utility that helps to define the needed settings for solaris for db2
    is has todo with message queues..... (/etc/system)
    see installation guide of db2 on solaris where this is explained

    The dbosconf will give you kernel setting.

    use db2 terminate before connecting to another instance.
