OAS Cluster / OC4J Cluster without using LBR ?

Hi all,
In one of our client running OAS 10.1.3.3, there is requirement for High Availibility, but investing for a hardware LBR may be too much for them on this phase.
We think of doing this : using two nodes for OAS :
server_1 : OHS1 + OC4J1
server_2 : OHS2 + OC4J2
for Load Balancing we plan to use MOD_OC4J.
Yes, we cannot do load balance between OHS1 & OHS2, so if server_1/OHS1 fails. Use has to manually access through OHS2.
Without LBR, is there any better solution than this ?
Thank you,
xtanto

You can also use Oracle Web Cache product which can not only do load balancing for you but at the same time provide other features like page caching and compression that will improve the performance.

1d cluster array replace value in a 1d boolean array (without using Loop)

Hi ,
is there a way to replace the values (string , boolean) of a 1D array Cluster with value of 1D boolean array without using loop ?

Replace Array Subset requires that the array elements are type compatible with the elements that you want to replace. That seems not the case in your example.
And the For Loop is anything but slow. How many billion elements do you expect your array to have to worry about performance of the for loop? With the type definition of your example even a ready made LabVIEW function would have to do internally a for loop too, since the boolean data inside the original array can not be in a continous memory area.
Maybe if you show us what you try to do with the for loop we can understand better what your concerns are. As it is from the front panel image alone it is really hard to understand what your imagined problem might be.

Hi Friend,
I see your code.. there is no other way than using for all entries for your situation.. how ever i saw ur code and a small recommandation in the change of code.
SELECT bukrs belnr gjahr budat FROM bkpf INTO TABLE i_bkpf
WHERE bukrs = p_bukrs AND "COMPANY CODE
gjahr = p_gjahr AND "FISCAL YEAR
budat IN s_budat. "POSTING DATE IN DOC
IF sy-subrc = 0.
if not p_hkont is initial.
SELECT bukrs belnr gjahr hkont shkzg dmbtr FROM bseg INTO TABLE
i_bseg1 FOR ALL ENTRIES IN i_bkpf
WHERE bukrs = i_bseg-bukrs AND "COMPANY CODE
belnr = i_bseg-belnr AND "A/CING DOC NO
gjahr = i_bseg-gjahr. "FISCAL YEAR
ENDIF.
i_bseg[] = i_bseg[]1.
delete i_bseg where hkont ne p_hkont.
else.
Your existing logic...
endif.
In this way you can avoide writing two selects on bseg..

BPEL + AQ + Load Balancing + OAS Cluster

Hi all
Is there a way to provide load balancing when reading AQ messages (JMS queue, not topic) to a OAS Cluster?
Explaining:
A BPEL server reads a flat file and send JMS messages using an AQ adapter. In the other side, there is a Java application running on a OAS cluster expecting the JMS messages, reading the queue on the AQ. As there is just one queue and many consumers (6 applications instances running on the cluster), how can I provide JMS load balancing between these 6 applications?
Sorry if this is not the correct forum to post, if you could recommend another forum I would be glad.
Thank you
Marcelo

Hi,
thanks for your answer. could you please be more specific? We have found something in the JMS specification:
JMS Spec 1.1 / Sun:
6.11.1 Durable TopicSubscriber
Only one session at a time can have a TopicSubscriber for a particular durable subscription. See
Section 4.3.2, Client Identifier, for more information.
So only one instance (JVM) can have the JMS-connection open to the Topic. How do we load balance these messages then into the Oracle Application Server?
As a workaround, we we have currently deployed a "singleton EAR" which acts as a messaging bridge. It transfers messages from the topic into an "incoming queue" at AQ database. That queue is configured and visible on all OC4j instances. Is this the right way to load balance messages on a OC4J/OAS cluster?
grüße,
\thomas

Deployig to a Cluster without losing session.

Hi,
          We have a cluster setup with 4 servers. We use HttpSession and

          possible to redeploy the application to a cluster without losing
          session ?.
          Thanks,

          Not with WebLogic session replication. The session replication is "lazy"
          (only when something happens) so the best approach is to make sure there are
          no imcompatibilities and then cycle the cluster one server at a time, maybe
          one server every hour (or whatever your session timeout is).

Cluster Without StorEdge

Hi .,
I am new to clustering.
We are having two Sun Sparc 490 R servers with Solaris10 installed
which we are planning to configure as a Two-node cluster.
Can anybody tell me whether is it possible to install the two node cluster without any storEdge..
Thanks & Regards
Suseendran .A

Please check docs.sun.com as Hartmut suggested. It is all documented there.
You can install Sun Cluster software for free on as many systems as you like. However, as soon as you need support, i.e. you are running on a production cluster, you will need to buy the licenses and get a support contract. You will also need to have your installation validated and it would be a good idea to go on the training course too.
However, if you are just a developer, then it is free to use (as you probably don't need any support).

How to upload files in cluster without bringing down the cluster.

Hi,
Here is my problem:
My weblogic portal 7.0 application should run in 24x7 environment. The production
system is running in a cluster mode with external staging. Both the managed servers
are pointing to the same application sync database.
So to give a solution to this problem, we are trying to bring down one managed
server down and apply the patches into that managed server without bringing down
the other. Since webflow files and entitlements needs to be synchronized with
the portal database. If we perform a sync on the portal database, there might
be a chance that it might corrupt the existing portal database state. Our deployment
would not be complete unless we perform a sync on the other managed servers. So
we could not able to update the latest pathces into the cluster without bringing
down the cluster.
What I would like to know is "Is there any work around to get rid of this problem?".
I would be delighted if any one provides the solution.
Thanks & Regards,
Ratnakar

Hi Ratnakar,
When you perform sync you do it against the admin server which in turn does it
to the managed server. If you want to apply any changes to webflow you can do
it on the live system itself. I mean apply the new webflow and entitlements and
do the sync on the live system. Also while doing sync there are two modes. One
mode will sync only the modified changes and the other will apply all of it. You
can opt for the first option by which you can sync only the modified changes.
This may bring a small disturbance but it will be unnoticed.
The other option is to have two separate domains(each having one admin & one or
more managed servers) which may be having two separate portal databases. In this
way you can apply patches to one domain while other domain may provide the service.

How do i setup WTC in cluster environment using WLS6.1 sp3?

Hello:
the situation is:
(1)Two solaris machines.
(2)one WLS domain.
(3)one admin server and four managed servers in this domain.
(4)we cluster these 4 managed servers.
(5)each machine contains 2 managed server.
Here is the problem,
when we start managed servers in the same machine, the wtc is ok, but when we start managed servers in diffent machine, the wtc fail.
here is the error message:
[Error][Cluster][Conflict start: You tried to bind an object under the name tuxedo.services.TuxedoConnection in the JNDI tree. The object you have bound from 10.64.32.188 is non clusterable and you have tried to bind more than once from two or more servers. Such objects can only deployed from one server.]

Determining Cluster Members Using a NamedCache

Is it possible to get the cluster members using a particular NamedCache?
Is it possible to add a listener which listens for members getting/returning (ensure/release) a particular NamedCache?
Is there a concept of groups within a cluster membership? Some way of both indicating what a particular node will be doing (say if you wanted to have a "nodata" member which held no objects in its partition and a "data" member which did hold the objects and could have the same configuration file, only somehow give it the parameter to indicate which an instance would be) as well as identify it from the cluster info (get all cluster members of the "data" type)?
--Tim

1) It's possible to get all cluster members that are
using (or providing storage for) a given cache
service:Excellent. Just what I was looking for.
More generally, starting with Coherence 3.2, there
are number of <aThis is what we need. I used storage enabled as an example, but we want to have roles for cluster members, so this is the better solution. We're currently on 3.0, but I guess this is a good impetus to upgrade.

Hi theresita,
i would like to retreive payroll results from it's allocated cluster tables .
1. U want the remuneration (monthly salary )

How do you create an array without using a shell on the FP?

I want to be able to read the status of front panel controls (value, control box selection, etc.) and save it to a file, as a "configuration" file -- then be able to load it and have all the controls set to the same states as were saved in the file. I was thinking an array would be a way to do this, as I have done that in VB. (Saving it as a text file, then reading lines back into the array when the file is read and point the control(s) values/states to the corresponding array element.
So how do I create an array of X dimensions without using a shell on the front panel? Or can someone suggest a better way to accomplish what I am after? (Datalogging doesn't allow for saving the status by a filename, so I
do not want to go that route.)

Thanks so much m3nth! This definitely looks like what I was wanting... just not really knowing how to get there.
I'm not sure I follow all the icons. Is that an array (top left with 0 constant) in the top example? And if so, that gets back to part of my original question of how to create an array without using a shell on the FP. Do I follow your diagram correctly?
If I seem a tad green... well I am.
I hope you understand the LabVIEW environment and icons are still very new to me.
Also, I had a response from an NI app. engineer about this problem. He sent me a couple of VI's that he threw together approaching this by using Keys. (I still think you are pointing to the best solution.) I assume he wouldn't mind m
e posting his reply and the VI's for the sake of a good, thorough, Roundtable discussion. So here are his comments with VI's attached:
"I was implementing this exact functionality this morning for an application I'm working on. I only have five controls I want to save, but they are all of different data types. I simply wrote a key for each control, and read back that key on initialization. I simply passed in property node values to the save VI at the end, and passed the values out to property nodes at
the beginning. I've attached my initialize and save VI's for you to view. If you have so many controls that this would not be feasible, you may want to look into clustering the controls and saving the cluster as a datalog file.

Clustering on single box without using multihoming

is it possible to set up a cluster between two instances of weblogic on the
          same box without using multihoming, but using different port numbers (or any
          other non-multihome solution).
          andrew park


Using the same port number is the requirement for setting a cluster. So, the
          answer is no.

Print Crystal Report directly from C# without using Report Viewer

Hello All,
I need to print a crystal report directly to the printer without using ReportViewer in C#. I've a CrystalReport2(belowCode) which requires a query (Select * from JobHeader where JobNumber='J012345') to display all the data. I'm stuck with database connection
and putting all the data to DataAdapter in C# (Below Code). I also have 8 subreports in my CrystalReport2. Can somebody please give me hand on this? I'm struggling with it. Thanks.
