EXS24 question on keyswitching and round robin

I imported a Giga patch into EXS24, and the Giga patch imported two groups which are keyswitches.
However, I don't want to keyswitch between them. I'd like EXS to alternate between the two groups. In Kontakt-speak, this is called round robin.
How can I get that to work? I scoured the plug-in reference manual and found nada.

It's not a well-detailed item, but EXS can do it. (It's also called "Round Robin" in Gigastudio.)
Let's say your zones have been assigned to two groups, "Clarinet Staccato 1" and "Clarinet Staccato 2," and you want them to alternate every time they're played to lessen the machine gun effect.
Load the instrument. Click "Edit" in the EXS plug-in window.
Enable the viewing of "Select by" for groups.
For Clarinet Staccato 1, set "Select by" to "Group:" Now assign the Group to "---start---"
For Clarinet Staccato 2, set "Select by" to "Group:" and assign group to "Clarinet Staccato 1."
In other words, one group "starts", and the other plays the next keystroke after the first group has been heard.

RDS 2012 Connection Broker and round robin DNS?

Hi,
I have a set-up with three session host servers and one of them is also a connection broker. Round robin DNS is configured for the three servers and the clients, who are all on our internal networks, can connect just fine to the farm name. My
questions is, is there any point in having round robin configured since the connections still need to go through the CB? Could i just have one DNS-record for the farm name pointing to the CB? My initial though was that round robin would add
redundancy, but does it realy? I've tried to find answers on this but none of the articles and posts i've found are realy clear to me.
Quite often the initial connection for clients is slow and my theory is that it's caused by the RR DNS records.

Hi,
Thank you for posting in Windows Server Forum.
I think we need to have DNS RR entries for our RDS environment because DNS RR will be used by RDP clients to connect to the RD Connection Broker servers. Once when we allowed the entries of all server to DNS RR, when there is alternate connection need to capture
for following server it will provided by DNS RR.
During the connection process, the end nodes (RDVH, RDSH, RDWA) will get configured with all the RD Connection Broker server names, and they will randomly choose one to connect to. The RDP clients will use the DNS Round Robin name configured to connect to the
RD Connection Broker servers randomly.

Multipath and round-robin

Hi,
does anyone can tell me how to enable / disable round-robin for multipath.
And how to check if round-robin is enabled or not
Thanks *T

I think the topic requires a bit of reading. You should find an answer here: https://linux.oracle.com/documentation/EL5/Red_Hat_Enterprise_Linux-5-DM_Multipath-en-US.pdf

WLS Cluster Servlet not "sticky" - continuous round robin (WLS 6.1 SP2)

          We have WLS serving as a proxy (with HttpClusterServlet) to a cluster of WLS servers
          running a WebApp with in memory HttpSession replication.
          However, subsequent calls from a browser continue to round robin through the cluster
          instead of returning to the same server.
          We have enable cookies in the browser.
          We have configured replication in the web.xml file.
          Is this an issue with SP2 perhaps?
          thanks in advance,
          -Mark


          We've noticed this as well, see my recent post. It definetly seems to be different
          from WL5.1.
          Sometimes we also see the same HTTPRequest going to BOTH servers in our cluster.
          We were testing with only one browser window and one user, and occasionally both
          clusters process the same request.
          We are using IIS with the proxy plugin and Round Robin. We installed the WL6.1
          verison of the plug in aswell.
          It would be great if you could configure WL6.1 to be sticky where one user sticks
          to one server until failover.

Exchange 2013 and DNS Round Robin downside?

Hi guys,
I have a question regarding Exchange Server 2013 (SP1) and the use of DNS round robin.
I have a customer that currently is running 2 CAS servers with NLB and we are currently investigating if it would be appropriate to move to a DNS RR solution so we can remove the CAS servers and install the CAS role on the Mailbox servers.
(yes I know that CAS with NLB and Mbx with DAG cannot be used on the same server)
What would be the downside of DNS RR?
Request 1 will go to first MBX server, Reqeust 2 to second MBX server, Request 3 to third MBX server and then start over again. If MBX server 1 goes offline, it will still be used within the DNS RR solution and clients will be redirected towards that server.
But how will clients react? Will Outlook 2010/2013 timeout since the server is not responding and do a autodiscover lookup again and then hopefully jump on the DNS that points towards another server?
Is this true for pop/imap or a receive connector for SMTP relay aswell?

Hi Fredrik,
Hope this helps out...
Round robin doens't check the load on the network interfaces.It just passes on to the next one; for example Server1, Server2
If server1 has a lot of traffic on his nic he still get more traffic onto his nic when round robin wants to.
NLB gives some checkes on the load on the interfaces. Therefore it will make sure that that all servers has about the same amount of traffic.
In Windows NLB we can able to create port rules for the virtual ip which is not applicable when you go DNS Round Robin
DNS round robin the clients will see different IP addresses Wherea NLB uses single IP Address
DNS round robin is not a good solution for redundancy. If one of the nodes goes down, you first have to go and remove its A record from the DNS server but then it may take some time before such a change is propergated. In the meantime you may have a number
of clients attempt to access the dead IP.
With load balancing you can remove a host from the set immediately (if it doesn't detect an unresponsive host automatically). The only affect of a downed server on the clients would be if some of the clients had session
data on that server.

E2013 namespace, unbound and DNS round robin

Hi,
Just check Ross Smith's blog abuot
namespace for E2013. He stated on "Figure 1" that VIPs per DAGs are behind single namespace "mail.contsoso.com" and clients reach those by DNS round robin. Anybody knows the answers for the questions:
How clients find the other VIP1 if VIP2 is down, but client has got on the responce from the DNS with VIP2's IP?
Do you need to have one IP per DAG? Would be it be possible to have one VIP only?

Hi,
The re-connection is based on TTL value. You can look the following thread:
https://social.technet.microsoft.com/Forums/exchange/en-US/8381c957-1189-4380-9e05-48f10ec15933/support-dns-roundrobin-for-exchange-2013-clients?forum=exchangesvravailabilityandisasterrecovery
HLB can detect when a specific Client Access server has become unavailable and remove it from the set of servers that will handle inbound connections, but DNS round robin can't do this.

Does anybody know any software for the Mac that I can run round robin, single and double elimination tournaments?

Does anybody know any software for the Mac that I can run round robin, single and double elimination tournaments? I help run tournaments but using excel for pool play and the web for bracket play, but if wifi is not available I have no way of running brackets for prize play. Can some one help point me in the direction of software that I can use locally on my Mac Pro.

Any ideas , if you think its a bug can u identify the bug id as I cannot find it .

Hello
I can see that you use ascending , that why you hit 1st channel.You have to choose one of these commands ascending or descending
I have a question here , for your incoming calls which channel hits ?.FYI isdn bchan-number-order descending is enable by default , so if you need to change you have to type ascending. Can you just share incoming calls which channel hits?.This is because before you define your outgoing calls , you have to check your service provider channel used, and this to avoid error channel is not available.
Command
Router(config-if)# isdn bchan-number-order {ascending | descending}
Purpose
Enables B channel selection for outgoing calls on a PRI interface (optional).

Command Tilde round robins between windows of an application but does not work in Most Recently Used mode

Hi All,
Suppose I have 5 excel sheets open and I want to toggle between 2 excel sheets on which i'm working on currently. How do it do it in Mac ? Cmd-~ round robins between all the open excels. Alt-Tab in windows work on the Most Recently Used concept. Is there a way to achieve this in Mac ?
Regards,

Not a reply to this specific question, just a quasi-relevant comment that might help some folks.
In Leopard, and with (for example) English and Russian chosen in System Prefs under "Language" and the keyboard shortcut set to command+space, I would always see the flag change in the menu bar as soon as command+space were chosen. Now, under Snow Leopard, hitting command+space seems not to make the change. But it does make the change, you just need to take your fingers off the keys first, then the flag will change.

Round Robin was not happening for my cluster with WebLogic Proxy Plugin

          Hi,
          I configured my cluster with software load balancer, HTTPClusterServlet. By default,
          it is load balancing with Round Robin Algorithm. That means one HTTP request
          goes to server1, and the other HTTP request goes to server2. However, it is not
          what I can see no matter for the requests in one HTTP session or not.
          Say I open two browser, and log into my application with two different users,
          one is "cyang", the other is "xpression". Then the HTTP request (for servlet/jsp)
          from two browsers always go to the same server1, server2 is not invoked at all.
          I did see one time, with only one session (one browser with "xPression" user log
          in), the most requests go to server1, suddenly I am brough into log in page, then
          I noticed that the request for "xPression" moved to server2 although server1 is
          still alive. Therefore, at most, I can say it is "Random", rather than "Round
          Robin".
          What is the real meaning for HTTP servlet/jsp load balancing algorithm? Does
          Round Robin mean request go to each server in turns? Does it have to be different
          session or it can be within one session?


It should be sticky. If not, then bug / config error.

ok, thanks, I'll have a look at that.
Going back to my issue... Since I stopped the User Profile Service on the Application server, now I'm getting these non-stop messages in the log:

This time, the messages are referring to the same server - the Application Server. In my original question, I should've differentiated the server names when I pasted the message. Originally the message was referring to the Application
Server and Affected Endpoint was referring to a WFE. I'll edit my original post to make it correct.

RD Web Access / RD Connection Broker - NLB/Round Robin or both?

Hi
Can someone point me to documentation that can assist with Infrastructure scaling and HA config of the RD Web Access/RD CB roles?
We have a successful PoC consisting of RD Web and RD CB on a single server (no GW required as we're using UAG) and several hosts. Now looking to port to production, thinking of scalability and HA. Looking to serve 300-750 users.
Thinking so far:
RD Web Access role across 2 servers using NLB
RD Connection Broker across 2 servers - (maybe same as Web Access machines?) But CB appears to operate using DNS Round robin. (https://msfreaks.wordpress.com/2013/12/23/windows-2012-r2-remote-desktop-services-part-2/)?
Can CB use NLB?
Which is preferred for the CB role, NLB or DNS round robin?
Cheers
Lea

Thanks Amy, they're really useful links. Why is it so hard to find these....or even an implementation/scaling guide for 2012?
TP - you are my hero, thanks for answering so many of my posts :-)
I was hoping RD Connection Brokers supported NLB as I've also read this is a far superior technology (see below). Here's my architecture thinking:
1. Install the CB role on two individual servers
2. Add NLB to the CBs
3. Follow
here , here and thanks Amy
here for SQL and HA mode (we run Full SQL on an independent server)
Question(s):
a. If SQL is not using AlwaysOn and therefore an SPF, what are the consequences of SQL outage? Does RDS fail completely?
b. If SQL is an SPF, is it worth enabling HA for CB presumably to gain load balancing? This
is a fascinating graph that would suggest little need based on latency for our farm of 20 or so hosts! All servers are on VMware 5.5 therefore inherent redundancy.
We may still choose HA but possibly for MS patching reasons such the farm (minus SQL server) can be patched without downtime...
I found this NLB/RRDNS description useful also
Network Load Balancing is superior to other software solutions such as round robin DNS (RRDNS), which distributes
workload among multiple servers but does not provide a mechanism for server availability. If a server within the host fails, RRDNS, unlike Network Load Balancing, will continue to send it work until a network administrator detects the failure and removes the
server from the DNS address list. This results in service disruption for clients. Network Load Balancing also has advantages over other load balancing solutions—both hardware- and software-based—that introduce single points of failure or performance bottlenecks
by using a centralized dispatcher. Because Network Load Balancing has no proprietary hardware requirements, any industry-standard compatible computer can be used. This provides significant cost savings when compared to proprietary hardware load balancing solutions.
Thanks again

NLS Redundancy using DNS Round Robin

Hello, I have searched the internet and this forum for my question but I couldn't find the answer anywhere.
Would it be an option to use DNS Round Robin as a 'fail over' mechanism for the DA NLS Server?
To explain our situation a little: We have a few branch offices and it happens sometimes that the site-to-site VPN tunnel between the branch office and the main office breaks (e.g. internet outage in the main office). In those situations it would be best to
have a NLS server in another office to prevent users from losing conenctivity to the network because of the first NLS server being unreachable (we have a full-mesh network between the offices).
But how does the DA mechanism respond to a DNS result with multiple IP addresses when querying for the NLS server? Most browsers will go to the 2nd IP address in case the 1st IP address is unreachable in such a situation. Will DirectAccess also do this?
I hope I explained our situation and question OK.

Jason,
I may have found something else. Apparently netmask ordering uses a default subnet mask of /24 (255.255.255.0) This is why the subnet must match. Apparently you can change the netmask used by netmask ordering:
Description of the netmask ordering feature and the round robin feature in Windows Server 2003 DNS
http://support2.microsoft.com/kb/842197
Not every customer may use this solution, but it might provide an solution for some customers. It all depends on their address scheme. Allow me to explain...
Imagine you have one datacenter and three branch offices. Each branch office owns a /16 subnet:
- Datacenter (10.100.0.0/16)
- Branch Office 1 (10.110.0.0/16)
- Branch Office 2 (10.120.0.0/16)
- Branch Office 3 (10.130.0.0/16)
Of course the whole /16 sunnet is not used on a site, intead multiple VLAN's with a /24 subnet are used at each site. A VLAN for servers and clients.
Now imagine you have an NLS in each server VLAN at each site. You configure RR for those NLS. If you query from a server next to an NLS, that NLS will be on top of the DNS query result. if you query from a client in another VLAN, the client will get
random DNS results because the client has another network ID. This is because the default netmask used by netmask ordering is 255.255.255.0 (/24).
If you change the netmask used by netmask ordering to 255.255.0.0 (/16) that will give you the nearest NLS on top.
But not every customer uses a /16 subnet for each site. So, that's why it won't be usable for everybody.
Ok, it is not an Enterprise solution and does not get the nobel prize, but what do you think?

Ah, ok...sorry I assumed you knew that! Normally NMO needs to be 'tuned' to match the branch office subnets to get the expected/best results. That KB is pretty invaluable to setup it up properly. Like you say it does depend on customer having logical/consistent
subnet boundaries definitions for it to work effectively though. I never said NMO was perfect :)

ACE howto: ¿Classic round-robin if cookie not present?

Hello team:
My server farm behind the ACE will be used for applications that may or may not send cookies.
So I have been asked to configure the ACE to be aware of a certain cookie in order to stick client to server as expected. In paralell, I have also been asked to execute a classic round robin algorithm if no cookie is present on the HTTP sessions.
Then my question is: ¿ will my ACE, configured with the "sticky http-cookie ..." command, default to a classical round-robin algorithm if no cookie is detected in the HTTP request from the client?
Your hints will be greatly appreciated.

Round robin DNS for load balancing between multiple network adapters (Xserve)

I'm attempting to use 'round robin' DNS to load balance between the two ethernet adapters of an Xserve.
Both ethernet adapters are connected to the same LAN and have static IP addresses of 192.168.2.250 and 192.168.2.251.
The DNS zone for the server's local domain/host (macserver.private) has a machine record with both IP addresses (set up in the Lion Server UI).
Having read up on round robin DNS, I would have expected DNS requests for 'macserver.private' to be answered with the two IP addresses ordered at random, achiving my aim of requests being served at random via each ethernet adapter.
However this doesn't seem to be the case. Doing a 'nslookup' from any of the network clients results in the two IP addresses being listed in the same order everytime. And pinging 'macserver.private' only ever results in a response from the same address.
Does anyone know why this is the case? Does Lion Server use a non-standard DNS configuration? Are there any additional settings I need to configure in Lion's DNS server to make adopt a round robin approach to responding to requests?
Thanks in advance for any help!

Be careful what you wish for
Round Robin DNS is rarely the best option for 'load balancing'. At the very least it's subject to caching at various point on the network - even at the client side, once the client looks up the address it will cache that response - this means that subsequent lookups may be served from the client's cache and not refer back to the server. Therfore any given client will always see the same address until the cache expires.
I suspect this is what you're seeing.
You can minimize this by setting a lower TTL on the records. This should result in the response being cached for a shorter period, meaning the client will make more requests to the server, with a higher change of using the 'other' address.
However, you're also going to run into issues with the server having two interfaces/addresses in the same LAN. This isn't recommended.
As Jonathon mentioned, you may be better off just bonding the two interfaces. This will provide an automatic level of dynamic load balancing without the latency of DNS caches, as well as automatic failover should one link fail (as opposed to round robin DNS which will cause 50% of requests to fail until the client cache expires and a new lookup is performed (and, even then, there's still a chance the client will try to use the failed link).
