Load balancing for specific services in RAC
Hi,
I have a two node RAC database 11gR2 version.I am planning to create 2 services for the database.For one of the services I dont want to enable server side load balancing and for the other one I want to enable load balancing.Will the following setting work
services:
srv1 -- load balancing not to be enabled
srv2 -- load balancing to be enabled
DB configuration:
For srv1 I will not use SCAN ip and I will connect using the vip of the servers.
For srv2 I will use SCAN ip and i will set the remote_listener(to SCAN:port) parameter and local listener parameter accordingly.
Will this serve my purpose
Thanks
Sekar
If the database is admin-managed, I shall suggest that rather than playing with the remote_listener parameter , set one service as preferred for one instance.For the other service, let it be preferred on both the nodes. The service with just one instance as Preferred won't be able to use loab-balancing as there is just one instance available for its disposal.

Load balancing and transparent failover in RAC 11g
Hi,
The only way to configure load balancing and transparent failover in RAC 11 g R2 is using the clauses LOAD_BALANCING and FAILOVER on the tnsnames.ora of application server.

Setting up Load Balancing for 11i for Intranet & Internet Access
Our current environment for 11i (11.5.5) is accessed only internally (via Intranet). We need to allow outside access (via Internet) also for self-service apps (ie. HR). Oracle Support/Metalink has stated that Load Balancing (note 148155.1) is the only supported method to have multiple (Apps Servers) systems access a single database. Could I get feedback from anyone who has implemented Load Balancing for 11i? Additionally if someone has implemented this for both intranet and internet access how has your company setup? Do the secondary server(s) from the Load Balancing note reside in the DMZ? And thus the primary app server and database reside inside the firewall? Thanks....
Hi,
We are using 6 middle tiers for internal access for intranet access and 2 middle tiers in External DMZ with only web server running for Extrenal Access over Internet for Self Service.
You Implement one Load Balancer for first 6 internal Middle Tiers with site level profiles pointing to Internal .
You implement second Load balancer for external 2 middle tiers with server level profile options for these two servers pointing to External Load balancer .

Load balancing SMA web service and SMA end point URL
Hi,
We have set up the recommended 3 servers with Azure Pack, SMA Web Service and Runbook Worker. We are now wanting to configure the Azure pack portal to setup the SMA endpoint url for the web service. Before we do that, we are assuming we should
load balance the web services to answer on 1 url (ie, smaws.domainname.com).
1. Is there any guidance or things to consider when load balancing the 3 web services to answer to 1 url. We will probably use f5 since that is what we use.
2. The end point url that we configure for Azure Pack automation should be this load balanced URL correct?
3. Should we have the Azure pack installed on just one of the servers or all 3. We did all 3 but it seems like server2 and 3 just redirect to 1 anyway so I am assuming the URL for Azure pack is stored in a db somewhere.
4. Are there any other components of SMA/Azure Pack that should also be load balanced?
Thanks
Thanks LanceSo in this case you need to register the SMA Runbook Workers (do this on machine 1):
$webService
= "https://localhost"
$workers
= (Get-SmaRunbookWorkerDeployment
-WebServiceEndpoint
$webService).ComputerName
if($workers
-isnot [system.array]) {$workers
= @($workers)}
$workers
+= "MachineName2"
$workers += "MachineName3"
New-SmaRunbookWorkerDeployment
-WebServiceEndpoint
$webService -ComputerName

Load Balancing in SICF Service
Hi,
I have set Up Load Balancing for a Logon Group in the SICF service.
In transacion SMMS, the parameter ms_Service_port_xx is maintained for HTTP for each server in the landscape.
Is this all I have to do for Load Balancing or there is any additional settings ?
Also, how to use the Session Timeout parameter in the SICF service (Just below Load Balancing )
Thanks
AnandHello,
The Logon group in SICF does not do any load balancing by itself.
HTTP Load balancing is the job of the SAP web dispatcher which connects with HTTP to the message server to get the information about application servers and logon groups.
You can also use directly the message server bu it is a bad solution because it's not really load balancing but merely redirects. A browser shortcut would redirect always to the same application server.

How to enable Network load balancing for Enterprise portal
Hello,
We have installed EP 7.0 central instance(00) and dialog instance (01) and would like to enable network load balancing between these two EP servers.Have installed network balancer and the configuration has been done at network level.
The below URLs are being used for accessing the portal
Central instance :
http://CIhostname:50000/irj/portal
Dialog Instance:
http://DIhostname:50100/irj/portal
Both the port number has to be same for enabling load balancing.In order to acive this we have to map this port to http port by making some changes in Visual Administrator.
Can you please let me know step by step procedure or any link where i can find the same?
Appreciate your response
Thanks,
VadiDear Jay,
Thnaks for your reply.
No...NLB will helpful in load balancing between different 2 different application (Ep)servers.
We are using microsoft network load balancer.Found the service http provider in VA for making those changes.
Any way thanks.

Urgent: Load balance the shared services server
Hello Experts,
One of my customer would like to know that is there a way to load balance the shared services server i.e., Register one essbase server with more than one Shared services server, so that if one shared services fails the other can authenticate the logins for the essbase server.
Also, referred the following weblink for 11x, Table 3. EPM System High Availability and Load Balancing Matrix
http://download.oracle.com/docs/cd/E12825_01/epm.111/epm_high_avail_11111/frameset.htm?ch01s04.html
Do we have any docs for version 9x?
Environment:
Essbase 9.3.1.3.00
OS : IBM AIX on POWER Systems (64-bit) 5.3
Any suggestions would be of great help. Thanks in advance.
Regards,
SonalI would not attempt any changes until 9.3.1 service fix #16 is released.
Oracle is back-porting clusterware support to with service fix # 16.
HSS 9.3.1sf 16 "active passive failover cluster with Oracle Clusterware 11g, for hss web app and openldap"
Based on the Oracle escalated support resources I have been in touch with solutions are not supported. Please realize this is not load-balancing and is fail-over support only.
To my knowledge there is not a "active-active" 9.3.1 Shared Services that is supported by Oracle.
You can read more about an active-passive fail-over at: http://www.oracle.com/technology/products/bi/pdf/epm-hss-high-avail-windows-whitepaper.pdf
They are supposed to release a 9.3.1 white paper once service fix #16 is fully released and has been client tested.

Network load balancer for Agentry applications
Hi Expert,
I'm going to implement a SAP Mobile Platform solution that will use an agentry application and I need some clarification about the HA configuration and the usage of the network load balancer and relay server. Just for information I'm going to use SMP 2.3 SP4.
My understanding is that Relay server is a reverse proxy and load balancer for SMP but It can't be used for the agentry applications. Is this correct?
Based on the standard configuration in order to balance the load of the client devices in the SMP cluster I have to use a Network load balancer, therefore the technical architecture of my solution should be the following:
|Agentry Client device| ----> | Network Load Balancer | ----> | SMP and Agentry Cluster| -----> |Back end systems|
Is this correct? I didn't find specifications about the Network load balancer.. Is there a list of the Network load balancer products supported from SAP for agentry application. Is there any best practice on the network load balancer?
Thank you in advance for you collaboration.
BR

Tags edited by: Michael ApplebyBecause we don't test any directly with our QA we don't have have a preferred products. Talking to our consulting group they normally just use what the customer already has installed in their network. Both Software or hardware load balancers has been used.
The key part needed for the load balancer for Agentry 6.0.x and SMP 2.3 (not SMP 3) that it is set to TCP Pass through.

Does Traffic Manager provide database load balancing for MySQL?
I need two VMs to implement MySQL Cluster in Windows Azure. VMs allow configure endpoint load balance set for Mysql, but I did not find tcp protocol in Traffic Manager. Does it provide this service for database
load balancing?Hi,
Traffic Manager works on the DNS level and routes traffic between public endpoints that sit behind a common DNS name. So you can't use this for your scenario.
However, You can implement
load balancing for VMs in another way.

What is the alternative of F5 BIG-IP LTM Load Balancer for OEM 12c
We want to implement service load balance, however oracle recommended
F5 BIG-IP LTM Load Balancer for OEM 12c
How much it is cost? and is there any free alternative we can use which supported by Oracle?
ThanksApart from F5, Cisco is another SLB vendor. I am not sure about any free alternative though.
Note that regardless what SLB that you pick, it should meet the requirements documented in section 29.3.2.2 of the EM12c Release 3 Administrator's Guide:
The SLB must provide support for multiple virtual server ports. Enterprise Manager typically requires that up to 4 ports are configured on the SLB (Secure Upload, Agent Registration, Secure Console, Unsecure Console)
Support for persistence. HTTP and HTTPS traffic between the browser and the OMS requires persistence
Support for application monitoring. The SLB must be capable of monitoring the health of the OMSs and detecting failures, so that requests will not be routed to OMSs that are not availa

Reverse Proxy and Load Balancer for SMP 2.3 and Agentry Application
Hi Expert,
I'm putting in place a mobile solution composed by SMP 2.3 SPS 4 and SAP ECC 6.0. In the SMP 2.3 I created the agentry server and I have deployed my agentry application.
My SMP/Agentry infrastructure is composed by two servers therefore I need a load balancer for balance the load into the several servers. Furthermore I need to use a reverse proxy in my DMZ zone.
Based on what indicated in the SAP note "1904213 - SAP Mobile Platform Server Release Information" the Apache Reverse Proxy is not supported for Agentry clients. Agentry uses nginx for Reverse Proxy.
I also found the following document How-to-Guide for Reverse Proxy and Load Balancing in SAP Mobile Platform 3.x that explain how to set-up a reverse proxy and load balancer with nginx and apache.
Both the SAP note and the HOW to document are refereed to SMP 3.0 and not to SMP 2.3.
I would know if the NGINX must be used also for SMP 2.3.
Any suggestion/information is appreciated.
Thanks in advance

Installing 2 Application server and 1 DB server and load balancing for 11i
Hi,
I need info on how to install and configure load balancing for 11.5.8 on Win2000. The scenario: 1 db server DB, 2 apps/web/forms servers AP1 and AP2. Using rapid install you can only specify one db server A and one form server in multi node installations, right? How do I install the form server on AP2? Can I use the same config.txt? The computer name for AP2 is different.
Thanks & Regards,
JagalI have the very same issue. We want to install 4 web/form servers on a hardware load-balancer and the issue is we can only specify one forms server.
Does anyone know the secret bullet here?
Thanks

Load Balancing for Microsoft Orchestrator application
Hi Folks,
We are trying to configure Load Balancing for Orchestrator Server.
We have closely 200 users running a workflow.. so in that case, we need to configure the Runbook Server as a application load balancing cluster, so please do share me the configuration guides..
Regards,
Venu
Best regards, Venu.I'm in the middle of doing this right now. There is a doc on metalink (233428.1) that details the process. I would highly recommend trying this in dev/test env first. Even though the instructions are very straight forward and not very complicated, I'm still having configuration issues.

Load Balancing, User Visible Service objects, Runningman
1. Load Balancing
Load Balancing a partition has nothing to do with single or multi-threaded
behaviour of that partition. If you load balance a partition it means that
you can start 1 or more copies of that partition. How many to start can be
specified. If the partition is load balanced there will be router partition
that routes calls to any of the services in that partition.
Now let us look at a special kind of partition (load balanced partition
that has an Env visible SO and a user visible DbSession). This is one of
the design patterns to acccess the database efficiently. Each of these
partitions are single threaded because DbSession is inherently single
threaded. This partition is single threaded because Dbsession is single
threaded and not because the partition is replicated.
Another case is when you make a partition load balanced and it has only
SO(s) made out of tool classes and does not have Dbsessions then each of
these partitions can run multi-threaded beacuse there are no
single-threaded objects to make the partition single threaded
2. User Visibility
Case A - If you have only User visible SO(s) in a partition then each
behaves like a global named object. Whoever accesses it will get a copy of
their own.
Case B - If you have a user visible SO and an Env Visible SO in the same
partition then the user visible SO will be private to the partition and
cannot be accessed from outside that partition.
3. Running Man
When you run an application by clicking on the running man Forte uses its
default partitioning scheme and runs the application. The partition scheme
that you made will be used only when you run the application distributed or
from the partition workshop. This is the time you might encounter errors if
your partitioning is not right.
Hope this helps.
NirmalDon,
You are right. I should have said - Forte uses its own partitioning scheme
not the default scheme you see when you open partition workshop.

Actually, clicking on the "running man" from the repository or project
workshop will cause the application to be run VERY differently thanrunning
it distributed.
It's not technically correct to say that the default partitioning schemeis
used with the running man.
Forte consulting offers a deployment workshop that covers the finerpoints
of this and other distributed issues.

Automatic load balance for oracle RAC
Hi there,
we have application, that use local oracle 9i database and every users use terminal application. That meaning, users do connect to hostname via terminal and invoke application.
We want migrate to RAC with cluster composed with 2 nodes. On every node must be
unique oracle_sid, but database is same on disk array.
My question is how configure users terminal profile which be comensatory automatic load balance .
ThanksHi,
This software simulates a real environment.
It creates a schema with tables, sequence, index, functions, etc..
Preferably in a client host it simulates several users (configurable) connecting to the database.
Then the test is simulated like in the real environment.
