1651.0. "/REENTER dangers?" by FUNYET::ANDERSON (Bye George) Thu Oct 22 1992 19:21

At my site there are two people who share the same VMS username and ALL-IN-1
account.  Should the second person be using the REENTER qualifier on a regular
basis?  If there are dangers associated with this, what are they?

    Hi,
    
    In V2.n there used to be 3 main problems:
    
    1. File Cabinet locking meant that there were problems if both users
       were accessing the same document.
    
    2. If the users are WPS-PLUS users then they cannot edit at the same
       time because of lockouts on file WPSDEF.WPL
    
    3. Interaction by permanent symbols. Applications that use these may
       well assume that only one user is updating them . An example is the WP
       main menu which sets the current document to $WPDOC. So if both
       users are on this menu then users will find their current document
       changing unexpectedly!
    
    In V3.0 problem 1 has now been fixed, but problems 2 and 3 remain.
    
    Cheers

1651.2In V3.0, it's easyto do this sort of thing safely!IOSG::PYEGraham - ALL-IN-1 Sorcerer's ApprenticeFri Oct 23 1992 10:2315
    Further to Stuart's points,
    
    In V3.0, we do all the checling of document access via ACLs and Rights
    IDs, which are specific to a single VMS account, so we *STRONGLY
    RECOMMEND* that you stop doing this sort of thing!
    
    In V3.0, it's easy to set up two different accounts, one for each
    person, and give them shared access to any documents they both want to
    edit.
    
    Additionally, most security type people like only one person to be able
    to log into any particular account so that any messages or other things
    can be traced to one individual.
