How to config in this architecture to achive load balance?

We have a XI which has a dialog instance.now we use the XI to connect to R3 system using abap proxy and to a no-sap system using JDBC.
no-sap sys(DB2)->JDBC adapter<-xi(CI+Di)->r3
The question is how to achive load balance,using web-dispatcher or other method?
Thanks in advance!

How to make IIS plug-in do STICKY load balancing

There are two classes of scalable services: pure and sticky. A pure service
is one where any instance of the application can respond to client requests.
A sticky service is one where a client sends its requests to the same
instance; those requests are not redirected to other instances.
It seems to me that weblogic IIS proxy plug-in does not support the sticky
load balancing.
Could someone give me some information on how to make the proxy sticky?
Is there configuration parameters for this?
Thanks,
-Lei

I set the cluster.
It seems to me that there is some problem with the Set-Cookie mechanism of
the plug-in.
Sometime it set the cookie in my browser, sometime it is not.
Even from the wlproxy.log, I could set something like
Fri Aug 03 17:56:12 2001 Hdrs to
client:[Set-Cookie]=[AribaNode=O2tII92qHlP2tpZjUV0m5ued1s6X028cUPu24QcGj1Q25
AE5VXOd!1782877802312707887!ltang.ariba.com!8001!7002; domain=ariba.com;
path=/]
But the cookie is not set in my browser, what might be wrong here?
Thanks,
-Lei

I do believe that this will not work since if clustering is not enabled, a
cookie will not be set on the browser that contains the primary and
secondary server.
You are specifying two different ports in your servers. You need to use
clustering in order to get this functionality with the plugin.Furthermore,
you will achieve fail-over.

Here is what I did for the examples under the bea sample directory.
I put the following in test1/WEB-INF/weblogic.xml
<session-descriptor>
<session-param>
<param-name> CookieDomain </param-name>
<param-value> *.ariba.com </param-value>
</session-param>
<session-param>
<param-name> CookieName </param-name>
<param-value> AribaNode </param-value>
</session-param>
<session-param>
<param-name> CookiePath </param-name>
<param-value> /test1 </param-value>
</session-param>
</session-descriptor>
</weblogic-web-app>
I add the following in iisproxy.ini
# This file contains initialization name/value pairs
# for the IIS/WebLogic plug-in.
WebLogicCluster=ltang.ariba.com:8001,achu.ariba.com:7001
ConnectTimeoutSecs=20
ConnectRetrySecs=2
Debug=ALL
WLLogFile=c:\tmp\wlproxy.log
WlForwardPath=/test1
DynamicServerList=OFF
CookieName=AribaNode
I use SesssionServlet.java as an example
When I involk http://proxy/test1/SessionServlet, I always get 1
if I use
http://proxy/test1/SessionServlet:AribaNode=................................
I could see the session becomes sticky.
If I do not want to use URL rewriting, what should I do in order to makethe
session STICKY
for this example.

If you leave the CookieName untouched on the WebLogic side, then there
should be no reason to make the change in the plug-in.
But yes, you need to make sure the cookie names are the same.

"Mark Vaughn" <[email protected]> wrote in message

Actually, you also need to make sure you set the "CookieName" in theplugin.
That let's the plugin read the cookie set by WebLogic to determine
who
the
primary and secondary servers are for that session. Otherwise, theplugin
has no
way of knowing if you are establishing a new session or returning to
an
existing
one. The cookie will tell it if you have a current session and who
it
should
send you to for continuing that session, or failing that session
over.

Without having clustering enabled, you will not get Sticky load

You need to have clustering so that a cookie is sent back to the
client
that
contains information about where it's session is located.
Otherwise,
you
are just going to get round-robin each time.
You can refer to the following page for more information:

I run two standone (Admin server) weblogic servers on machine1
machine2.
Then I deploy application test.war on machine1 first, then onmachine2.
Should I make machine2 as a managed server and machine1 as an
admi

Will this make the session sticky?

It would help us to know how you have iisproxy.ini configured.
Sticky
load

correctly.
How have you setup the plug-in?

How does CEF perform equal and unequal cost load balancing?

hello
How does CEF perform equal and unequal cost load balancing?
thanks

Hello 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

How to get a server name through the load balancer

Hi.
I'd like to get the server name where is my application installed. There are some servers and clients access there throuth the load balancer. When I try to get it with request.getServerName(), I get the virtual address of the load balancer.
Any suggestions?
Thanks.

Dear Sikindar;
THanks for your cooperation, but I believe that these Tcodes will eb helpful if I know the table name, actually we don't know its name and that's what I'm asking about, how can I get the table name for the ABAPer?

How to monitor targets which are controlled by LOAD BALANCING mechanism

Hi,
I have installed Enterprise Manager 10.1.0.3 and upgraded it to 10.1.0.5. Then i have applied the Application plug-in patch for managing Oracle Applications.In my environment, we have two concurrent managers and four forms servers which are using Load Balancer.Please let me how to manage these concurrent managers and forms servers in that scenario.Would highly appreciate your suggestions regarding the same.Thanks in advance.
Regards,
Vamsi Manyam

This note shows how to configure OEM behind a load balancer.
The question was how to use OEM, not behind a load balancer, to monitor other targets which are behind one or different load balancers.
For example, to monitor :
Forms on server A and B behind load balancer LB1.
Forms on server C and D behind load balancer LB1.
Forms on server E and F behind load balancer LB2.

How Can I Make This Sql Query To Load Data Correctly (sql server)?

Hi guys
I have a datagridview where the third column is a custom column with all days
of a month. It takes data with a query who distinct the column Improve.
Here is the code :
Private Sub fill_impro()
dgImprove.Rows.Clear()
Try
Dim i As Integer = 0
Dim query As String = "SELECT Improve,Price,Active,Idate FROM (SELECT Improve,Price,Active,Idate, ROW_NUMBER() OVER (PARTITION BY Price ORDER BY Price) AS rn FROM tblImprove) tmp WHERE rn = 1"
cmd = New SqlCommand(query, clsMSSQL.con)
myDR = cmd.ExecuteReader
If myDR.HasRows Then
While myDR.Read
dgImprove.Rows.Add()
dgImprove.Rows(i).Cells(0).Value = myDR.GetDecimal(myDR.GetOrdinal("Price"))
dgImprove.Rows(i).Cells(1).Value = myDR.GetString(myDR.GetOrdinal("Improve"))
Dim myday As Integer = DatePart(DateInterval.Day, myDR.GetValue(myDR.GetOrdinal("Idate")))
dgImprove.Rows(i).Cells(myday + 1).Value = myDR.GetInt32(myDR.GetOrdinal("Active"))
i = i + 1
End While
End If
myDR.Close()
Catch ex As Exception
MsgBox(ex.Message, MsgBoxStyle.Critical, "Σφάλμα")
End Try
End Sub
And here is the result :
http://i60.tinypic.com/28gwf83.jpg
The column Active value is 1.
The problem is that column Active values are missing (red values in image).
How can i fix that ?
Thanks in advance

try like this
Dim Price As Decimal
Dim improve As String = String.Empty
While myDR.Read
Dim myday As Integer = DatePart(DateInterval.Day, myDR.GetValue(myDR.GetOrdinal("Idate")))
If Not (myDR.GetDecimal(myDR.GetOrdinal("Price")) = Price And myDR.GetString(myDR.GetOrdinal("Improve")) = improve) Then
i += 1
dgimprove.Rows.Add()
dgimprove.Rows(i).Cells(0).Value = myDR.GetDecimal(myDR.GetOrdinal("Price"))
dgimprove.Rows(i).Cells(1).Value = myDR.GetString(myDR.GetOrdinal("Improve"))
Price = myDR.GetDecimal(myDR.GetOrdinal("Price"))
improve = myDR.GetString(myDR.GetOrdinal("Improve"))
End If
dgimprove.Rows(i).Cells(myday + 1).Value = myDR.GetInt32(myDR.GetOrdinal("Active"))
End While
and change your sql statement to just
SELECT Improve,Price,Active,Idate FROM tblImprove WHERE Active = 1

Hi,
Maybe you can try below code, I have changed the order by of the row_number(). Therefore it will sort on the date, and you will get the first date icm with improve cell. If this is not what you are looking for, please explain what the output should be.
SELECT Improve,Price,Active,Idate
FROM
SELECT Improve,Price,Active,Idate, ROW_NUMBER() OVER (PARTITION BY Improve ORDER BY ldate) AS rn
FROM tblImprove
) tmp WHERE rn = 1

How the Load balancing happens in CPO

Hi All,
On what bases the process engine selects the process or request and how the load balancing happens.

Hi!
I am a little confused by the question (as it refers to "request"), but I am going to assume that you are asking how a High Availability Process Orchestrator environment with several servers chooses which processes running on which server.
The answer to that question is...
In general, processes to be executed are split equally between all servers. The only piece of data being taken into account during process instance assignment is the current load on the servers (as counted by the number of top-level processes, not counting child processes). For example, suppose that there are 3 servers in the environment, and server A is running 5 top-level processes, servers B & C are running 3 top-level processes. When new process is started (e.g. on a schedule or manually or triggered via an external event), it will be assigned to either server B or server C for execution, because servers B & C have less load. If under the same circumstances (A:5, B:3, C:3), there are 4 processes started at the same time. When the work is distributed, the total expected work 5+3+3=11 (existing work) and 4 (new work) will be distributed equally with, with servers B&C each getting 2 new processes.
This is a general load balancing algorithms used by the servers in HA environment to decide which server runs which process instance.
There are other factors that come into play, as some processes/activities can only run on server A or server B for technical limitations (e.g. SAP work against a particular SAP System can only be executed from one server in the environment). When those come into play, the work may end up distributed unevenly.
Note that available memory, CPU load, or disk space on servers are not directly taken into account during load distribution.

5.1 Audio with 3 jacks: How to config this ?

Good evening everybody,
I'm having since short a 5.1audio set, a logitech x540. I love this set, not too priced for a 5.1set. I'm coming from some crappy cheap trust 2.1set, so this is a big improvement.
But now the problem: my set needs to be connected to my motherboard with those '3 jack cables', because it's not having a coax cable. (normal for a budget set). But my motherboard has got only those 3 'normal' jacks. But not a big problem, i found the following in my motherboard guide:
Light Blue : Surround
Lime : Front Speaker Out
Pink : Center/bass
So hardware seen it isn't a problem to use those jacks . So i connected them like told in my motherboard manual. But now i don't get them working under linux. I don't know how to config it. I'm having the following audio card:
00:10.1 Audio device: nVidia Corporation MCP51 High Definition Audio (rev a2)
I'm using alsa, so i've searched in alsamixer, but i didn't find anything usefull there. Anybody who can help me with this pls ?

I have a very cheap C-Media PCI CMI8738-MC6 6-channel sound card connected by three jacks to Logitech 5.1 speakers. I also have a headset for Skype connected to the onboard sound.
Here's what I know:
1) To always get the sound card module to load before the onboard sound module, I have added snd_cmipci to my "modules" list in /etc/rc.conf. This means the cmi card is always card 0, the module for the onboard sound gets loaded automatically later.
2) I have ~.asoundrc as follows:
# 6 channel dmix:
pcm.dmix6 {
type dmix
ipc_key 1024
ipc_key_add_uid false
ipc_perm 0660
slave {
pcm "hw:0,1"
rate 48000
channels 6
period_time 0
period_size 1024
buffer_time 0
buffer_size 5120
# upmixing:
pcm.ch51dup {
type route
slave.pcm dmix6
slave.channels 6
ttable.0.0 1
ttable.1.1 1
ttable.0.2 1
ttable.1.3 1
ttable.0.4 0.5
ttable.1.4 0.5
ttable.0.5 0.5
ttable.1.5 0.5
pcm.duplex {
type asym
playback.pcm "ch51dup" # upmix first
capture.pcm "hw:0"
# change default device:
pcm.!default {
type softvol
slave.pcm "duplex"
control {
name "Software Master"
card 0
# for aoss
pcm.dsp "duplex"
pcm.dsp1 "duplex"
3) To allow amarok to play each speaker individually using a 6 channel DTS .wav file I added the following to my ~.xine/config
audio.device.alsa_surround51_device:plughw:0,1
4) You can download a 60MB 6-channel DTS test file here. It is in swedish but tests each speaker individually.
My info came from browsing the Alsa wiki
