1210.0. "some general OpenVMS Scheduler questions" by PTOVAX::PEARLMAN () Fri Feb 07 1997 16:17

    Some general questions regarding OpenVMS Scheduler
    
    1.  The customer has a two node cluster.  He has asked about failover. 
    I didn't see anything in the SPD but I did some references within this
    notesfile that failover might be a feature in an OpenVMS cluster.  Is
    it so and where do you read about it?
    
    2.  When the customer buys the server license does it come with a
    client?  The SPD wasn't clear.  If they had only a single system would
    you buy 1 server license and 1 client license?
    
    3.  The customer would like to do the Scheduler setup from a PC using
    EXcursion.  Any reasons why this might not work?

     As far as I know, there is no scheduler failover. Scheduler needs
    to be running on all nodes you want scheduler to work on.
    
     If you have the server license, you don't need a client license,
    unless you plan to run both server and agent on the same node (???)
    
    I use scheduler through Xcursion, the only problem I have is that the
    AUX options screen, not fitting on the screen. You can change the
    font size down, but then you can't read it. :-)

It can do failover if you have the second node licensed.  I have asked CA
tech support to help us with exactly how to set it up.

A server license includes the client.

The next version is Scheduler (V2.2) is based on Motif and will allow your
customer to do setup on a PC using Excursion.  We're not sure is you can
do it with older versions and I have asked CA tech support to clarify that
for us.  (See NOTED::POLYCENTER note 787.9 for the release schedule for
the next version).

I just got better answers from Ca engineering:

    
>>   1.  The customer has a two node cluster.  He has asked about failover. 
>>    I didn't see anything in the SPD but I did some references within this
>>  notesfile that failover might be a feature in an OpenVMS cluster.  Is

Yes, this can be done.  You must install the software on a common disk in
the cluster and start the software on both servers.  You don't have to do
anything in the software itself.  
    
>>  3.  The customer would like to do the Scheduler setup from a PC using
>>  EXcursion.  Any reasons why this might not work?

This can be done as well.  It's an undocumented feature.

If you have any further question, please let me know and I will put you in
touch with the engineer.  We just don't want to publish his number and swamp 
him with calls.

Without going to license questions : Scheduler when started on more than one
node in the cluster automaticly fails-over when a node drops. The nsched
processes have a lock on each other and are notified via the VMS distr. lock
mgr whenever a node fails out the cluster. Jobs are only failing over as long
as restart on crash has been specified AND the job is allowed to run on that
node (so node field is empty).

You do not need client license to run scheduler interface. Scheduler client
product is more a scheduler agent: scheduler jobs are fired from the
agent were the scheduler job database is on the server.

It works ok for Excursion V2 for me since several years.
