Error description

  • When a system has a GLOBALTCPIPDATA input specified in the
    Resolver process configuration (the SETUP DD), a copy of the
    contents is kept to support NMI processing.  To ensure that this
    is always current, each time a new application performs a
    res_init() call a check is performed to detect when that input
    has been updated.
    
    The problem is that the mechanism to notify the RESOLVER address
    space of that update is to have the application issue a MODIFY
    RESOLVER command.  But in most instances, the user running that
    application will not have the authority to issue a MODIFY
    command, so a security violation results along with the
    following message:
    
       IEE345I MODIFY  AUTHORITY INVALID, FAILED BY SECURITY PRODUCT
    
    If using RACF for SAF functions, a message similar to the
    following will accompany the above:
    
       ICH408I USER(xxxxxxxx) GROUP(xxxxxxxx) NAME(xxxxx xxxxx)
         MVS.MODIFY.STC.RESOLVER.RESOLVER CL(OPERCMDS)
         INSUFFICIENT ACCESS AUTHORITY
         FROM MVS.MODIFY.** (G)
         ACCESS INTENT(UPDATE )  ACCESS ALLOWED(NONE   )
    
    Note:  If a non-default name is being used for the RESOLVER
           process, that name will appear as the last two qualifiers
           of the referenced profile name.
    

Local fix

  • Issue a MODIFY RESOLVER,REFRESH command from an authorized
    user to stop the violations.  This can also be
    performed immediately after updating the referenced
    GLOBALTCPIPDATA input.

    * PROBLEM DESCRIPTION: Message IEE345I is issued from various  *
    *                      applications that reference the global  *
    *                      tcpip data after the global tcpip data  *
    *                      set has been modified.                  *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    When the global TCPIP data set has been modified a MODIFY
    command is used to notify the RESOLVER that it has been modified
    and that it should be reread for any updates.  However,
    installation security products prevent the MODIFY command from
    being executed since the application has not been given
    authority to issue a MODIFY RESOLVER command.

Problem conclusion

  • The resolver is amended to use an cross memory post of a ECB in
    the resolver address space for notification that the global
    TCPIP data set has been modified.
