Web Services Round Robin Service Load Balancer Event Endpoint Failure
I keep seeing these errors in the UlsTraceLogs:
SharePoint Web Services Round Robin Service Load Balancer Event: EndpointFailure Process Name: OWSTIMER Process ID: 3748 AppDomain Name: DefaultDomain AppDomain ID: 1 Service Application Uri: urn:schemas-microsoft-com:sharepoint:service:9b3095eda69947b299d2f873bbfee5ad#authority=urn:uuid:a01381a61b244525ab4fec30cde9dc5f&authority=https://ApplicationServerName:port/Topology/topology.svc

what do these errors mean?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. -
Client side load balancing and server side load balancing
Hello Team,
I need to know how to set up client and server side load balancing in oracle rac. What all things to be implemented like creating a service, tnsnames.ora settings etc.
And also if i used SCAN ip instead of VIP. how the settings will change.

How does CEF perform equal and unequal cost load balancing?
hello
How does CEF perform equal and unequal cost load balancing?
thanksHello Wang,
it is only EIGRP that can perform load balancing over unequal cost links.
For equal cost links CEF allocates 16 buckets and maps them to the the physical links.
the result of a binary operation is used to associated a packet to an outgoing interface:
Source IP address EXOR DEstination IP Address EXOR hash
the hash is a seed that changes only at every reload.
Actually the last 4 bits are used so that each flow can be classified in one bucket.
then the outgoing interface is the one asscociated to the result of the exor operation.
Another way to see is that m bits are used so that 2^m is equal to N number of links (if N is even)
the rule is simple and pre-established
Hope to help

Configuring 2 css11503s for multiple service load-balancing
first here's my present config on one of my CSS11503:
!************************** CIRCUIT **************************

ip virtual-router 2 priority 110 preempt

!*************************** GROUP ***************************
group BrowServ_Group
vip address 19.10.28.210
add service BrowServ-1
add service BrowServ-2
redundant-index 1
active
here are my questions:
1) how do I configure an additional vip address? e.g. I'd like to configure a vip - 19.10.28.215 to load-balance http traffic to 10.15.15.25 and 10.15.15.26?
2) I presently have a static route in my core router "ip route 10.15.15.0 255.255.255.0 19.10.28.210". (this enables the load-balanced servers to connect to Oracle servers on the Core network). do I need to configure a new route on my core router when I add the additional vip 19.10.28.215?
relevant references and/or examples will be much appreciated.
dayo1/ configure the following :
service web1
ip address 10.15.15.25
active
service web
ip address 10.15.15.26
active
content WEB
vip address 19.10.28.215
proto tcp
port 80
add service web1
add service web2
active
2/ I would create a redundant-interface and point your static route to this redundant ip address.
you should not use vip address in static route.
VIP address should only be used when you want to reach the vip address not a when you want a direct connection to the real server.

Database Native web services - load balancing, Instrumentation , security
Hello –
I’m proposing use of Database Native web service in our company. Our architects are asking following questions so appreciate your help
a. How do you load balance across the DB WS (is there a way to use the F5 to detect downtime and balance the load across the DB servers)? We will be using RAC configuration with 3 nodes.
b. Our architect have security concern as user id/password information are in the web service URL, which may prove to be an issue. Is there a way to mitigate this risk?
c. Instrumentation in this approach (db native services) is questionable due to development/auto gen of the service logic from the DB itself. We may investigate wrapping the services with OSB to give us an additional instrumentation, policy enforcement, endpoint mediation and security proxy. Thoughts??
d. Architect are curious regarding any potential performance issues this may have on the DB server.
ThanksHi
We've recently begun using Native Web Services, intending to roll out this approach across the enterprise, but we've encountered 2 significant problems so far, which you may want to consider before proceeding ...
1. NWS returns an exception if the underlying PL/SQL returns a null value - even if the PL/SQL has completed successfully, and null is a legitimate return value (see SR 3-6201969101 - it contains simple instructions to recreate the problem)
(I raised it in this forum but there were no replies - SOAP Fault when returning null from a Native Web Service Stored Procedure
2. The sequence of values returned in the NWS response message is the opposite to the sequence declared in the auto-generated wsdl - i.e. schema validation will fail (see SR 3-6209016991 - it also contains simple instructions to replicate)
We have coded a workaround for problem 1. where we return <EMPTY> in place of null, and check for it in the client, but without proper resolution we're not prepared to use NWS elsewhere
As a workaround for problem 2. we removed schema validation, again not ideal
Both SRs were escalated 9 days ago, but are still outstanding
Incidentally our database is 11.2.0.1, but I've tested on 11.2.0.3 and both problems are still present
We also wrap the NWS services using an OSB Proxy Service, and came across the same security issue that you describe (b) - to provide the credentials required for the NWS, simply create a Service Account (containing the credentials) inside OSB and attach it to the Business Service which invokes the NWS (http://docs.oracle.com/cd/E17904_01/doc.1111/e15867/service_accounts.htm)

SharePoint Service Load Balancing
Hi,
I used to install small farm with all services on one App Server. I have question about having multiple App Servers.
Can we install/start same the service on multiple app server for redundancy ? If so, how the load balancing is managed ?
If that true for all services (Search, Excel...)
Thank youThe Topology Service uses Round Robin.

Hi,
I have a question about load-balancing facilities for Time service. If I
schedule a TimeScheduleDef object to run at certain intervals, does the
run-time environment take care of load balancing it across multiple machines
on a cluster?
Thanks,

load balancing is performed.

SMA Web service load balancing issues.
Hi, We have configured 3 servers with the SMA web service
https://machinename1.domain.com:9090
https://machinename2.domain.com:9090
https://machinename3.domain.com:9090
We have load balanced these 3 web services using F5 load balancer and have the LB site set as https://smaws.domain.com
We used this URL with Windows Azure Pack automation endpoint and that seemed to work.
We are not sure if this is working properly or not.
How can we test? Should the URL to the web service contain a guid?
https://yoursmaserver:9090/00000000-0000-0000-0000-000000000000
We have tried the following but all of them produce errors.

We do have the webservice configured in IIS with host header smaws.domain.com, machinename and machinename.domain.local.

CEF and per-packet load balancing
We have four OC3 links across the atlantic and I was looking for a solution which would allow load balacing across the four links on a per-packet basis (not session). The objective is both resiliency i.e. being able to handle link failures transparently & balancing the load across all the links. BGP multptah looked like the ideal soultion. However, I was told that the CEF packet based load balancing is no longer supported by CISCO. Is this correct ? Is it applicable for all models ? Are there any other potential solutions?
Appreciate a response from the experts.Hello Rittick,
an MPLS pseudowire will use only one link of the 4 links based on inner MPLS label, it cannot be spread over multiple parallel links.
The MPLS pseudowire can travel within an MPLS TE LSP that can be protected by FRR.
per packet load balancing does not apply to your scenario.
You need to mark traffic of the critical application with an appropriate EXP settings. The EXP bits are copied to the outer (external) label.
On the OC-3 physical interfaces you will configure a CBWFQ scheduler providing 100 Mbps of bandwidth to traffic with specific EXP marking. This is elastic and over unused links bandwidth will be left available to other traffic.
On the LAN interface you need to mark the EXP bits in received packets using a policy-map
access-list 101 permit tcp host x.x.x.x host y,y,y,y
class CLASSIFY-BACKUP
match access-group 101
policy-map MARKER
class CLASSIFY-BACKUP
set mpls exp 3
class class-default
set mpls exp 0
int gex/y/z
service-policy in MARKER
class-map BACKUP
match mpls exp 3
policy-map SCHED-OC3
class BACKUP
bandwidth 100000
class class-default
fair-queue
int posx/y/z
service-policy out SCHED-OC3
applied on all pos interfaces. The MPLS pseudowire will use one link only. Different pseudowires can use different OC-3 links. Load balancing of MPLS traffic is based on internal label (the VC label of the pseudowire)
Note:
you should check if it is possible to mark traffic received on the incoming interface of the pseudowire otherwise you need to mark IP precedence nearer to the host.
Hope to help

A question about the SharePoint services load balancer
Let's consider a farm with one WFE and two app servers, A and B. Both app servers are running the Managed Metadata Service (MMS).
User requests a page from the WFE, which talks to the database server. The operation needs information from the MMS, so the WFE requests information from the round robin load balancer for SharePoint web services. Let's say server A is down.
Here's my question - what happens next?
a) The round robin load balancer tells the WFE the MMS is on servers A & B. The WFE tries server A, fails, and returns a failure.
b) The round robin returns servers A & B. The WFE tries server A, which fails. The WFE then tries server B.
c) The round robin returns either A or B, depending on which is next in rotation. The WFE tries the server returned. If the server returned is A, the WFE returns a failure.
d) The round robin returns either A or B, depending on which is next in rotation. The WFE tries the server returned. If the server returned is A, the WFE queries the round robin service again.
e) The round robin knows server A is down, returns only server B to the WFE.

Business Intelligence SolutionsWhen a Service Application is down, the application load balancer removes that endpoint from the load balancer. When it becomes available again, it adds it back. This way the WFE would just contact the MMS endpoint that was available, not try and timeout
against an unavailable endpoint.

Problem with WLIOTimeoutSecs in weblogic and apche CSS load balancer
Hi,
We are using Weblogic 11g, apache 2.2 and CSS load balancer for load balancing.
we have huge reports which take minutes to generate and hence we need higher value for WLIOTimeoutSecs. This works fine when we use server url but WLIOTimeoutSecs is not working when we use CSS load balancer.
We checked with our load balancing team they said CSS load balancer will not repost the request.
Here is the plugin configuration
<Location /*****>
SetHandler weblogic-handler
PathTrim /
WebLogicHost 'serevrip'
WebLogicPort 'port'
WLIOTimeoutSecs 3600
Idempotent OFF
WLProxySSL ON
DefaultFileName /***/***/index.jsp
Debug On
WLLogFile /***/***/***/***.log
</Location>
Could some please help me on this.
Thanks in advance
Regards,
VenkatHi Tarun,
The problem occurs when the SSL is enabled on apache. If I access the same URL over HTTP, the parameter WLIOTimeOut works fine.
Also I observed that, none of the parameters are getting applied to the plugin. I had switched on 'DebugConfigInfo'. With this the HTTP URL with ?__WebLogicBridgeConfig as query parameter returned the complete configuration. However when accessed with HTTPS the server did not return the configuration.
Is there a specific configuration to be applied when apache is used with SSL?
Thanks for your help,

Questions on replication and h/w load balancer
Why does h/w load balancer have to support passive cookies and inspect them to
dispatch the request to the primary server first? If we have in-memory replication
and if h/w loadbalancer just dispatches the http request from the client to any
of the weblogic servers in the cluster wouldnt this work?
Is it to pin the session to the creator server to minimize the chance of replication
misses due to n/w issues, member server slow speed, buffer overwrite etc.
-Shiraz
Yes, and previous to 6.1 (?) if the request showed up at the wrong server it
would fail.
