Error description

  • IBM Rational Developer for System z - RDz - v9.1
    
    You may see ICH408i error messages concerning STATVFS being
    issued under the RDz Threadpool rather than under the userid.
    
    IKJ56893I message may occur on disconnect because of the active
    single.logon directive in rsed.envvars
    
    These symptoms can occur when a user is forcibly disconnected
    from RDz 9.1
    
    You may see the following message in the RSE Daemon joblog:
    +FEK210I : <userid> was disconnected forcibly because of the
       active single.logon directive.
    
    The user may get the message that a MVS dataset
    <rsedstc>.RDZ.ID.<id> cannot be created under the RSED's STC
    id instead of the actual userid.
    
    This is the same problem as reported in APAR PI70554 for
    IBM zOS Explorer v3.0
    

Local fix

  • Remove the following rsed.envvars environment variable option:
       -DISPF_OPTS=&SESSION=SPAWN

    01.When a user session is disconnected by the single.logon
       directive in rsed.envvars, the output indicating the wrong

       <Daemon user> is the user id name by which RSE
       server(daemon) is running. That should be the user who is
       logging on and being disconnected. If the daemon user does
       not have permission to access the user log directory, syslog
       messages are output during the forcible disconnect operation
