    Is SRS required with no Public Access printers?

    I'm having a very hard time finding this out for sure. There seems to be
    some conflicting information in Novell's own documentation.

    The basic question is, can you safely disable SRS on all brokers on the
    network if you are not using any Public Access printers? Are there any
    other impacts at all of disabling SRS besides not being able to use Public
    Access printers? (And I mean disabling SRS ENTIRELY, not having SRS
    running on ANY broker on the entire network.)

    It's a long story but we currently still use queue based printing. We
    want to move to NDPS but our network people are concerned that the SRS
    service creates a lot of network traffic. Most of what I read on Novell's
    site implies that SRS is only used for Public Access printers. We won't
    have any of those. But there is some documentation that implies that SRS
    is used for more than just Public Access printers, but isn't clear exactly
    what else it might be used for or what other functionality you'll lose if
    you don't run it.

    On a side note, we plan to use raw NDPS, NOT iPrint. We have no use for
    the iPrint capabilities in our environment, and we want to leverage the
    built-in ability of raw NDPS to automatically deploy printers to
    designated workstations on login. (The only way I could find to
    automatically deploy iPrint printers is through ZenWorks, which is not an
    option for us.)

    Thank you.

    My Novell contact says there is a 85 to 90 % certainty that you should be fine.
    Do you want me to investigate further?

    I would greatly appreciate it. I'm about 85% confident myself based on
    what I've seen in documentation, but as I mentioned in my original post,
    there seems to be a bit of conflicting info in some different documents
    I've read. Our network people won't let us run with SRS, so our option is
    to verify that SRS isn't required, or we don't use NDPS/iPrint at all.
    I'd rather know that for sure before we start into a production
    deployment. I can do some testing in a lab environment, but I really
    don't want to get in a production environment and run into something that
    wasn't foreseen but might have been known about on Novell's side.

    Thank you!

    The IPrint Engineering Manager says:

    >if there are no public access printers in an iPrint environment, will anything

    bad happen if SRS is disabled?

    His response - "No. We encourage customers to disable it very often."

    Re: Is SRS required with no Public Access printers?

    someone else told me:


    The SRS service doesn't create any traffic at all on it's own, so his
    concerns aren't valid. All it does is register the broker(s) and PA
    printers with SLP. If he doesn't have any PA printers, no additional
    load gets created.
    And yes, disabling it will cause problems. His management tools will no
    longer find the Broker, or claim it's down, totally refusing to admin
    it.

    I very much appreciate you looking into it further, but I see two
    answers. Which is it? (I see the above answer but then there is another
    that you said was from the iPrint Engineering Manager that says we should
    be fine disabling SRS. I guess I'm inclined to believe the one that's
    from the iPrint Engineering Manager?)

    Also, the bit in the answer I quoted above about the SRS service not
    creating traffic on it's own is just plain false according to everything
    else I've read, and our own results with network sniffer traces. In some
    TID article I read on Novell's web site, there's something about all SRS
    agents on the network synchronizing with each other every 20 seconds, and
    there's no way to change that except to completely disable SRS.

    Don't know about the not being able to manage the broker without SRS
    though. I haven't seen anything specific to that one way or the other in
    any Novell documentation (which is one reason I'm so confused).

    It's still under discussion in the back room. <g> There are two schools of
    thought.

    I'm being told you should have SRS running on ONE broker, but not on every
    broker. This will cut down traffic.

    I'll watch and summarize the results for you.

    Thanks for the update. In our case, we don't want to run SRS on any
    brokers at all. Also, on another note, we're dealing with remote offices
    connected to the main office by 256k frame relay lines. There is a server
    in each remote office, but we don't want the SRS traffic going across the
    WAN (or running around our central network in the main office). All
    servers are part of the same tree but each remote office has it's own
    replica partition.

    Any further update yet?

    Thanks!
