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.

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 the system know which are Inventory cubes?while compres in ProcessChain

Hi,Experts
When I create a Cube compress in ProcessChain ,under the page there is a checkbox called No Maker for Inventory Cube,and I also know the Non-cumulative key figure can not be compress,
My question is how the system know which are Inventory cubes? and many cube create from ourself.

Hi,
I think,
- in the sap tables there are no information.
- the program reads the infocube definition and check: is there a non-***. value?

How to control a Load Balanced set in IaaS VMs using Text files

Hi,
I would like to control the Load Balanced nodes Using a resource to probe like active.txt in IIS than a Endpoint on the Management Portal.
The reason i need this is because the engineers in my team will have access to VMs but not to Management servers.
Any info on it is very helpful.
Thanks

Hi,
You can Control the access to the Load Balanced Set by using Network ACL. A Network Access Control List (ACL) is a security enhancement available for your Azure deployment. An ACL provides the ability to selectively permit or deny traffic for a virtual machine
endpoint. This packet filtering capability provides an additional layer of security.
Using Network ACLs, you can do the following:
Selectively permit or deny incoming traffic based on remote subnet IPv4 address range to a virtual machine input endpoint.
Blacklist IP addresses
Create multiple rules per virtual machine endpoint
Specify up to 50 ACL rules per virtual machine endpoint
Use rule ordering to ensure the correct set of rules are applied on a given virtual machine endpoint (lowest to highest)
Specify an ACL for a specific remote subnet IPv4 address.
Network ACLs can be specified on a Load balanced set (LB Set) endpoint. If an ACL is specified for a LB Set, the Network ACL is applied to all Virtual Machines in that LB Set. For example, if a LB Set is created with “Port 80” and the LB Set contains 3 VMs,
the Network ACL created on endpoint “Port 80” of one VM will automatically apply to the other VMs.
Hope this helps !

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.

I use SesssionServlet.java as an example
When I involk http://proxy/test1/SessionServlet, I always get 1
if I use

I could see the session becomes sticky.
If I do not want to use URL rewriting, what should I do in order to makethe

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.

Eric Gross wrote:
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:

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

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

I'm not sure what you mean . . . what won't work with Lion? It sounds like it did do some backups.

There is a way, but it's rather cumbersome. You have to start selecting a full system restore; there's a window showing all of the backups and the version of OSX.
Is there an app I could use to manage the snapshots if manually deleting them will cause problems and side effects later.

Safari how do i know which are my open Safari tabs in several windows?

Hi and good day,
It happens frequently that I have several windows open in Safari and in Chrome.
… and with a few tabs windows each.
My question:
How can I find a specific open page, which is somewhere on a tabbed window beneath other windows?
Is there an app to help?
It’s easier of course no problem with 'non-tabbed' windows, as the title will be displayed by the browser.
Hope this makes sense, and it is not unimportant for the workflow :-)

How to track beans which are destroyed, but no exception log?

According to the WLS console, we have two out of about 30 entity beans
which have instances which are being destroyed. However, I cannot find
the exception which is causing them to be destroyed. I see nothing in
the WLS logs, nothing in our own logs, nothing, nothing, nothing.
I am wondering if this might be because for those two beans, there are
finder methods which are being invoked, and which may not find anything,
in which case the exception is caught and processing continues
appropriately. Is this a scenario where a bean instance might be created
and then destroyed?
Any ideas on how I can determine why these beans on being destroyed, if
the above scenario does not apply?
Thanks!

Well, there are only 2 paths to 'does not exist' in the spec.
unsetEntityContext or system exception. If unsetEntityContext isn't being
called, then it must be a system exception. If that isn't being logged, the
container isn't obeying the spec. If a FinderException is causing the
destruction of the instance, that isn't spec compliant, either. A
reproducible test case and a support call may be your best course of action.
Bill
"Jay Schmidgall" <no@spam> wrote in message news:41dd5bd9$1@mail...
Well, I put logging in the unsetEntityContext method and it is
apparently not being called; max-beans-in-cache is not explicity set, so
it defaults to 1000, I believe, and the console tells me the cached
beans current count is under 50 for both.
On the other hand, the scenario I suggested does seem to cooincide well
with the destroyed count; that is, after the bean is not found by the
finder, the destroyed count goes up. From your description, that seems
like it is just coincidence, but it is definitely there.
bill kemp wrote:
Finder methods are called on a pooled instance of the bean. If the
finder
doesn't find the entity, a FinderException(which is just an application
exception) should be thrown, which is reported to the client, but the
instance is not destroyed. If a system exception is thrown, thecontainer is
supposed to log it before it destroys the instance. The only other pathto
destruction in the state diagram is when the bean goes from 'pooled' to
'does not exist' when the container calls the unsetEntityContext method.So,
maybe put some output code in the unsetEntityContext method to see ifthe
container is removing beans because of cache size considerations. Just a
guess. Do you have <max-beans-in-cache> set to anything in particular?

DB Tool List Table: How to access tables which are in different SQL database ?

Hi, All,
I'm working on a database application (SQL server) and is evaluating the NI DB Tool kit for this project.
One of the requirement is that I need to access tables which are in two different database
(say Table A in DB 1 and Table B in DB 2).
Our IT guys has linked Table A in DB1 to DB 2 and I verfied this when I use the SQL server managment studio.
When DB 2 tables are populated, Table A from DB1 is also there. I can also do the same thing using MS Access.
Table A in DB1 is avalaible to me enven though I only connect to DB 2.
Here comes the problem.
When I use DB Tool List Table.vi to access DB2, it does NOT list Table A in DB1. It only list the tables in
the database (DB2) which I make connection to (using DB Tool Open Connection.vi with a file DSN)
So my work around right now is to open two seperate connection to DB1 and DB2. However, this approach
obviously creates a problem when I have to access seperate database constantly in my application.
What would be a solution to this ? I've search the forum but only see one post that's somewhat related to
my question. (And it was posted on 2004) Perhaps I need to alter the code in the orignial VI (DB Tool List Table.vi)??
My IT guy told me he has not encountered this scenario since he writes codes in other enviroment such as
VB and others, and he's always been successful by linking tables to different database.
I hope my question is sound and clear since I really don't know much about database terminology.
Any comment/suggestion is much appreciated !!!
Thanks
Chad
Solved!
Go to Solution.

To josborne:
To answer your question:
- Are the two databases contained on the same SQL Server instance?
Or are the databases on separate instances? I assume they are on
separate servers, otherwise this wouldn't really be an issue. But its
good to know because it will affect how you build your SQL statements.
Yes they are on separate instances.
- Ask your IT people specifically how they "linked Table A in DB1 to
DB 2". I assume they used "linked servers".
Maybe I used the wrong terminology "linked." They created a "View of Table A (DB1)" in DB2 using the management studio.
Here is a screen shot of that. As you can see, dbo.VISUAL_WORK_ORDER is seen under LABVIEW database in the management studio.
I also see the same table when I make connection to database using MS Access.
Could you elaborate on "configure your SQL statement correctly" =) ? The purpose of using LabView's took kit is so that I can do
minimum SQL statements. Are you talking about modifying LabView's native VI (DB Tool List Table.vi) ?
Thanks for the information. SQL is just something new to me.

How to findout rows which are not null ?

Hi friends,
Can anyone tell me how to find out the no of rows which is having full data in each column (not null) ?
Ex:- TEST_TABLE having 1000 columns and lakes of rows.
myQuestion:- I need to find the no of rows which are filled with 1000 columns filled with not null data.
Thanks in Advacne.
Kishore.

Hello
You're just going to have to write the query with IS NOT NULL on each column. This will help generate the predicates for the WHERE clause to save quite a bit of typing...
SELECT
    ' AND '||column_name||' IS NOT NULL'
FROM
    all_tab_columns
WHERE
    table_name = 'TEST_TABLE'You can take the output and add that to
SELECT COUNT(*) FROM test_table WHERE 1=1 HTH

There are lot of aggregates in my system , so i should deactivate the aggregates which are not used from long back. so how to find out all those , can u plz guide me ,

You can also check the usage column of the aggregates. If usage value is high then the aggregate is used very frequently.
If there is no value at the last used then the aggreagete is not used at all.

How to find reports which are using sales tables

Table names are given but how to find which report is using these tables.Is there any method to find
or we have to check all reports manually?
Could any one pls suggest me here!
Regards,
sk
Edited by: 912736 on Jun 8, 2012 1:24 PM

Hi SK,
You can run a report from catalog manager that willl give you all answers requests and the subject area columns in use, you can map these back to the sales tables either manually or by linking (vlookup) to an RPD report that you can run from the Admin tool.
The Usage Tracking method is pretty good but you will have to match up the reports using the Logical SQL.
I'd do both methods and cross ref your results to ensure nothing slips the net.
