3498.0. "DECmcc configuration question" by MSAM00::MIKEWARREN (Technology Consulting, Malaysia) Tue Aug 04 1992 11:56

    A customer is planning to buy a VAXstation 4000/90 with 32MB memory 
    (RAM) and 1GB disk to run DECmcc. He will purchase a multi-user license
    as well. What he intends to do is as follows:

    DECmcc users will startup X-Windows server software (Xcursion) on the 
    PC and from the VAXstation. The system manager will log in to the 
    VAXstation and start up MCC and direct all display onto the users 
    screen. The command he plans to use would look like: 

	$ SET DISPLAY/NODE=xxxxx $ MCC/E/Interface=DECWINDOW; 

    where xxxxx is the node name of the user. 

    The operators of the DECmcc, both from VAXstation and PCs, are 
    suppose to retrieve information, acknowledge alarm, and perform 
    some other 'non-configuration' tasks. They will possibly use 
    datatrieve, DECgraph to do some reports.

    Questions are :  

    1. Will the above work ?
    2. Could the above configuration have up to 5 simultaneous sessions ?
    3. What is the recommended amount of RAM required, ie is 32MB sufficient ?
    4. What sort of system configuration is recommended ?

	Mike, Remember, you need the SPECIAL multi-user license for the workstation, not the standard VMS user licenses. However, given this, I think a VAX-4000 Model 100 or VAX-3100 model 90 would be better for this purpose. In regard to disk configuration, I'd put an RZ23L in for the system disk, plus 2 RZ26s with a Volume Shadowing License for the MCC subsystem. I tell customers that they can rebuild the system disk easily, but would have a real problem re-creating all that data they've collected. In addition, you'll need at least 1 RRD42 for software installation plus to keep the DECMCC docs on-line. If you want to keep all docs on-line, you'll need 3 RRD42s. I'd choose the non-workstation systems because they support more memory, more disks (SCSI, DSSI), etc. Ted
3498.2	DECmcc V1.2 - eXcursion - VAXstation 4000/90	CUJO::HILL	Dan Hill-Net.Mgt.-Customer Resident	`Thu Aug 06 1992 01:39`	38
	We are currently testing DECmcc on a seed VAXstation 4000 Model 90. It is quite fast (rated at 33 SPECmarks, 42 VUPS). We have 80 MB memory. It supports 128 MB. It has a turbochannel ethernet controller that we have rated at 9Mbps sustained on our LAN. There are some problems with the current V5.5-2S4 version of VMS which has given us some grief, so I would be a little uneasy about recommending it to a customer until the bugs have been worked out. As far as eXcursion is concerned, we tried using DECmcc to ship a window to a 486 PC. There were problems with limited screen real estate, plus the fact that windows didn't behave the way we expected. For example, the DECmcc navigation window would not "collapse" with the map window. The toolbox window did some strange things, too, as did the pull down menus. If I were you, I would stress test EVERYTHING as much as possible before I sold the customer anything. There are currently only 10 VAXstation 4000/90's. They are not scheduled to go into production until mid- to late August. Once the bugs are worked out, though, this will be a nice system. I do recommend a minimum of 64 MB of memory in any VAX, especially if you will be using it to serve windows. For PCs, we noticed that it cost us 1MB of memory PER WINDOW SERVED to support Pathworks nodes. Also, if you have a bad network, your X-windows response time will be affected. Nothing beats a local display. Regards, Dan
