How to load balance Agents across multiple Oracle Management Servers?

Hi everyone
We have the 2 OMS servers in our OEM environment. We would like to set up our management agents to load balance over these 2 servers...Or if not load balance then at least set up the agents so they can access either/or OMS.
I've looked through the documentation and in google, but can't seem to find the answer.
Can someone point me towards the documentation please
Thanks
R

OMS is just an appserver with a repository. You can load balance the appservers with an F5. You can load balance the repository with RAC.
So ... your options for load balancing and resilience are :-
1. one agent on each server, multiple OMS appservers load balanced, one RAC database (with dataguard standby)
2. two agents per server, two appservers, two repositories.
Both architectures work. Option 1 offers the best load balancing and resilience.

How to identify a user across multiple pages

Hi,
I'm doing a homebanking and I would like to know how to identify a user across multiple pages.
I have already take a look at HTTPSESSION, but I didn't understand.
Can someone help me.
I'm send the servlet Logon.
import java.io.*;
import java.sql.*;
import java.util.Date;
import java.util.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class Cons_logon extends HttpServlet
     private Connection conexao = null;
     Login1 login1;
     public void init (ServletConfig cfg) throws ServletException
          super.init(cfg);
          try
               Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
               conexao = DriverManager.getConnection("jdbc:odbc:bank");

     PrintWriter out;
          res.setContentType("text/html");
out = res.getWriter();
String opcao = req.getParameter("log");
Thanks

I would recommend using the authentication mechanism that's guaranteed by the servlet spec. If you do that, you can just call
request.getRemoteUser()
to get the user name across multiple pages.
If you want to use your own login scheme, you can create a new session object and map it to a user name somewhere in your app. Or you can just put the name of the user on the session. But the preferred way is to use the default authentication scheme defined by the spec.

How to load balance runbooks?

Hi,
Now I have successed to deploy an seccond Runbook Server in an test environment. But I have not fully understanding how the runbooks run on the primary vs standby. And I know that by default one Runbook Server can handle 50 runbooks, and how to scal out
runbooks?
How to load balance runbooks?
How to fail over runbooks?
/SaiTech

you can change how many concurrent runbooks are allowed to run on a single runbook server. 50 is just a default value.
you can assign a runbook to run on a specific runbook server (or more). this is the simplest way to load balance.
runbooks will failover automatically. do note that the runbook will start all over, hence you need to put in safeguards in your runbook. word of adwise is to keep runbooks small and chain them together. This makes them easier to recover.

How to load balance two link (resilient link)

How to load balance (if can) or failover two Fiber channel like as below?
interface GigabitEthernet0/1
switchport mode trunk
channel-group 1 mode active
channel-protocol lacp
interface GigabitEthernet0/2
switchport mode trunk
channel-group 1 mode active
channel-protocol lacp

Hi
You can use this "port-channel load-balance src-dst-ip", this will do a XOR on source & destination IP addresses and choose the interface G0/1 if the first bit of the result is 0 or the interface G0/2 if the first bit of the result is 1.
But you can check the path used with that command: "sh etherchannel 1 port-channel"
You can load balance with the mac-addresses too (it is the default mode I think)

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.

How to load text file data to Oracle Database table?

By using Oracle Forms, how to load text file data to Oracle Database table?

Metalink note 33247.1 explains how to use text_io as suggested by Robin to read the file into a Multi-Row block. However, that article was written for forms 4.5 and uses CREATE_RECORD in a loop. There was another article, 91513.1 describing the more elegant method of 'querying' the file into the block by transactional triggers. Unfortunately this more recent article has disappeared without trace and Oracle deny its existence. I know it existed as I have a printed copy in front of me, and very useful it is too.

Multiple SOA Managed Servers required

Hi
By default when we create a domain , we are provided with a managed server named (soa_server1) which we use for development. But in production/E2E T we may require more than one soa managed servers which should be added on to a cluster and load balance the request.
Is there any means i can create more soa servers in a domain after the initial domain build.?
Also do we have multiple em consoles or single em constitute all the soa managed server partitions?
Please help.

Load Balancing & Fault tolerance in Oracle Apps

Hello
I am pretty new to Oracle Apps and Oracle 9iAS
We are trying to asked to find out the ways of deplying load balancing and fault tolerance in Oracle Apps
I have gone thru the following articles of metalink and some more from google
Configuring Web Cache as a Load Balancer for Application Servers
Create new middle tier node in existing Apps 11i environment using cloning and then load balance
Integrating and using Web Cache with Forms 9i for Load Balancing
Running Multiple OC4J Instances From a Single Install of 9iAS 1.0.2.2
LOAD BALANCING ORACLE APPLICATIONS ON UNIX
Load Balancing in 11i
OC4J Clustering Setup
OC4J Load Balancing for Forms 9i
Setting up 11i E-Business suite using a hardware load balancer
Sharing an APPL_TOP in Oracle Applications 11i
In Oracle Apps Concepts pdf, found that
Load balancing occurs when there are multiple installations of web server, forms server, reports server, concurrent manager server etc
Lets consider forms server component of middle tier
Can there be multiple INSTANCES of forms server within SINGLE INSTALLATION ???
If it has to be MULTIPLE INSTALLATIONS, then it will require multiple physical machines
What is software load balancing then ???
Also read that
Oracle 9i AS instance is combition of Oracle HTTP Server (OHS) and one or more instances of Oracle9iAS Container for J2EE (OC4J)
Thus software load balancing can be implemented for Web server component of middle tier using multiple instances of OC4J ???
Forms metrix server configuration is hardware load balancing ??
What about Oracle9iAS Web Cache clustering ??
Please clarify the doubts and suggest me the way
Thanks a lot

dear all can any one help me on the following;
We want to install Oracle Apps 11.5.9 on 4 IBM AIX 5L boxes, the first node
will hold the database , concurrent and Admin Tiers. as for the other 3 nodes
it will hold the Forms/Web Tiers and we need to use forms metrics for load
balancing taking into consideration that we can't use Shared APPL_TOP. we tried
to find the way how to install and configure this solution but all the
documents are talking aboout the concept only and this concept is applicable.
We need the exact steps on how do the installation either using rapidwiz or any
thing else

How to load balance everything

Edit:
More up to date list is available on the wiki:
http://wiki.oracle.com/page/WCI+Load+Balancing
Its hard to find information related to deployment anymore, as there is no deployment guide for 10gR3 and a lot of information is scattered around in outdated blog posts. I'd like to keep a list of how to design every component for HA. I don't doubt that there are a lot of errors and things that need filled in so please reply with your additions and corrections.
h3. Types of load balancing referenced:
h4. external
refers to a hardware or software based load balancing handled outside Webcenter software
h4. MPPE
the 'massively parallel portlet engine' is the portal's ability to internally load balance web services that are configured with round robin DNS
h4. cold failover
I might have the terminology wrong, but I'm referring to when you have another instance of the product installed but disabled. The instance can be turned on in the event of an ourage of the primary component, but it is not automatically available.
h1. Portal
Load balanced with an external load balancer (sticky session enabled)
h3. References:
http://edocs.bea.com/alui/deployment/docs604/networking/c_loadbalancing.html
h1. API
h1. Publisher
Publisher is able to be load balanced by breaking it up into components: publisher admin, publisher redirect, published content
h2. Publisher admin
Cannot be load balanced, use cold failover
h2. Publisher redirector
MPPE (or external?)
h2. Published content
external
h3. References:
http://fsanglier.blogspot.com/2008/02/alui-publisher-increase-performance.html
h1. Collaboration
External / MPPE (with collab internal clustering)
(Although i'm currently having issues wtih this and someone reported that you can do without the collab internal clustering)
h3. Collab's API
When using the IDK to connect to collab, custom applications bypass the MPPE and communicate directly to the collab host, losing the benefit of the MPPE. In order to load balance in this situation, the collab host must use external load balancing. (is this true?)
h3. "Search" service (the collab one) (only applies to 4.5 or newer)
Install on same servers as collab?
http://download.oracle.com/docs/cd/E13158_01/alui/collaboration/docs103/install/install.htm#i1138897
h3. References:
http://edocs.bea.com/alui/deployment/docs604/networking/c_loadbalancing.html
recent collab outage related questions
h1. Document Repository
External
h1. (AD/LDAP) Identity Web Services
MPPE to the Web Services
External between Web Services and AD /LDAP servers (or use HOSTS files to point each ADAWS server to a differnet AD server?)
h1. Search
(grid search: 6.1 or newer)The portal can load balance search requests internally. Each search node has knowledge of other nodes, so only 1 node needs to be reported to the portal. When the portal starts up, the 1 search node that is registered with the portal MUST be available.
h1. Analytics
Analytics UI
(i'm not sure? i'm guessing anything would work here because the admin UI is pretty much read only on the database)
Analytics collector can be load balanced (as of 2.5)
http://download-llnw.oracle.com/docs/cd/E13158_01/alui/analytics/docs103/installALI/quickstart.html#wp1063387
h1. Automation
Load balancing for reduncancy is not possible. However, the work can be split up Automation servers are assigned to different folders. Don't assign 2 automation servers to the same folder, as they can compete for jobs. (?)
h1. Content Upload
(mppe / external)?
h1. ALUI Directory Service
h1. Remote Portlet Service
? (i'm gussing MPPE)
h1. Notification
? no idea
h1. What else am i missing?
Edited by: Joel Collins on Apr 27, 2009 6:52 AM

Here are few bits of info:
For load balancing for Analytics, that isn't officially supported yet for the UI and Administration components. It might work with sticky sessions from portal-to-analytics but that doesn't get you much. Improving the options there would be a good enhancement request.
For the collector, I think there are two important things to remember. Use broadcast mode. I've never actually seen it in unicast mode, but broadcast definitely works. Also, remember that this is all managed by Portal and Analytics - you don't use your own load balancer between Portal instances and the Analytics Collector instances.
Finally, ALUI Directory is not certified to be load balanced yet. On a separate note, ALUI Directory has a socket leak on Windows due to a bug in the version of Jrockit that ships with it. Upgrading the embedded application server for the ALUI/WCI installation to jrockit-R27.5.0-jdk1.5.0_14 will resolve it.

Hi everyone!
The following are the steps to load a excell sheet to oracle table.i tried to be as simple as possible.
thanks
Step # 1
Prapare a data file (excel sheet) that would be uploaded to oracle table.
"Save As" a excel sheet to ".csv" (comma seperated values) format.
Then save as to " .dat " file.
e.g datafile.bat
1,Category Wise Consumption Summary,Expected Receipts Report
2,Category Wise Receipts Summary,Forecast Detail Report
3,Current Stock List Category Wise,Forecast rule listing
4,Daily Production Report,Freight carrier listing
5,Daily Transactions Report,Inventory Value Report
Step # 2
Prapare a control file that define the data file to be loaded ,columns seperation value,name and type of the table columns to which data is to be loaded.The control file extension should be " .ctl " !
e.g i want to load the data into tasks table ,from the datafile.dat file and having controlfile.ctl control file.
SQL> desc tasks;
Name Null? Type
TASK_ID NOT NULL NUMBER(14)
TASK_NAME VARCHAR2(120)
TASK_CODE VARCHAR2(120)
: controlfile.ctl
LOAD DATA
INFILE 'e:\datafile.dat'
INTO TABLE tasks
FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"'
(TASK_ID INTEGER EXTERNAL,
TASK_NAME CHAR,
TASK_CODE CHAR)
The above is the structure for a control file.
Step # 3
the final step is to give the sqlldr command to execute the process.
sqlldr userid=scott/tiger@abc control=e:\controlfile.ctl log=e:\logfile.log

Query on Clustering,Load Balancing and Dehydration in Oracle BPEL PM

Hi,
I had a Few queries on Dehydration ,Clustering and Load Balancing:
1) In section 5.1 "Use Case for Asynchronous Web Services",insertion of a dehydration point is mentioned.What do you exactly mean by this.Can a dehydration point be inserted explicitly?OR we have to put a wait activity or something so that dehydration happens?
2) If a dehydration point needs to be inserted explicity arent we assuming that the invoke-reply will take long?But this might not be the case always.Is is a lso possible that an asynchronous process is not a long running one.
3) Can we configure administratively ,how much time the process (say 10 seconds or so)waits after which it gets dehydrated?
4) Consider a load balancing scenario,where we have 2 BPEL PM's (PM1 and PM2) running on 2 different App Servers (SRV1 and SRV2)in an clustered environment.
Scenario:
1)We have an asynchronous process which makes a call to a human task activity.
2)A request from client comes for this process.
3) The load balancing server forwards it to PM1 on SRV1.PM1 processes the request and calls the human task.
4) PM1 has not dehydrated the process.
5) The response from the Human User comes back to the Load Balancer before the process is dehydrated by PM1.It forwards this response to PM2.PM2 searches for the Process based on the Cor-relation ID and does not find it.
Can you tell me how this scenario is handled?
I would be grateful if someone can answer these queries or direct me to some place where it is already explained.
Thanks
Dileep

1) In section 5.1 "Use Case for Asynchronous Web Services",insertion of a dehydration point is mentioned.What do you exactly mean by this.Can a dehydration point be inserted explicitly?OR we have to put a wait activity or something so that dehydration happens?
Insert a java snippet with "checkpoint();"
3) Can we configure administratively ,how much time the process (say 10 seconds or so)waits after which it gets dehydrated?
No, this is due to the performance of your database.

Question on how does load balancing work on Firewall Services Module (FWSM)

Hi everyone,
I have a question about the algorithm of load balancing on Firewall Services Module (FWSM).
I understand that the FWSM supports up to three equal cost routes on the same interface for load balancing.
Please see a lower simple figure.
outside inside
--- L3 SW --+
|
MHSRP +--- FWSM ----
|
--- L3 SW --+
I am going to configure the following default routes on FWSM point to each MHSRP VIP (192.168.13.29 and 192.168.13.30) for load balancing.
route outside_1 0.0.0.0 0.0.0.0 192.168.13.29 1
route outside_1 0.0.0.0 0.0.0.0 192.168.13.30 1　　　　　　
However I don't know how load balancing work on FWSM.
On FWSM, load balancing work based on
Per-Destination ?
Per-Source ?
Per-Packet ?
or
Other criteria ?
Your information would be greatly appreciated.
Best Regards,

Configuring "tunnel default gateway' on the concentrator allowed traffic to flow as desired through the FWSM.
FWSM is not capable of performing policy based routing, the additional static routes for the VPN load balancing caused half of the packets to be lost. As a result, it appears that the VPN concentrators will not be able to load balance.

How to load-balance LotusNotes "Sametime" with CSS11500

I have 2 redundant CSS since a while, working fine. Recently I wanted to add load-balancing for the Chat service of LotusNotes Sametime. The problem is that the chat conversations are disconeected some how. On a first configuration, I didn't configure sticky mode on this content. Since then I added sticky mode "srcip" and a long sticky timeout (600 mn or 10 h.). But th eproblem is still the same. Can someone help ? Thank you. note : you'll find attached the configuration for the chat content.

Hi,
The CSS 11500 uses the ArrowPoint Content Aware (ACA) service to gather response time data for every flow for building statistical averages/variances for every service and content rule. The best servers are used, while the slow servers are pruned from the eligible list. This service also can manage persistent connections for e-commerce based on IP addresses (range), Secure Socket Layer (SSL) application IDs, and cookies.
As you are having only 2 servers for load-balance.
As your keepalive time is 30 sec which is quite high.
I suppose you should change your keepalive frequency 30 to
keepalive frequency 5
try this
as
using the default values of a 5-second keepalive frequency interval, a 5-second retry period interval, and maximum of three failures, a service can transition from the alive state to the dead state in 15 seconds; a 5-second interval between a keepalive response and the initial keepalive failure based on the keepalive frequency, and two failures, each occurring at 5-second intervals based on the retry period.

How to Load Balance Event Collection

Hi,
I got the Windows Event Forwarding working, but how can I load balance a huge number of souce computers to forwared their events to two or more servers in my domain?
Im Using Windows Server 2012R2 as my collectors and 2008R2 and after as my forwarders.
Thanks for your replies.

Hi DDerJoel,
Windows Event forwarding is a build-in functionality, easy to use. But it does not provide load balance function. System Center Operations Manager, as a full grown product,
provides more advanced enterprise monitoring solution.
Or you can refer the following related KB to optimize your log forwarding server.
