SSP5: Using multiple JVM for load balance performance?

Sun 12 MAY 2002
Apps 11.0.3
SSP5 patchset I
HP UX 11.0
db 8.1.7.2 (64-bit)
Load 60 concurrent sessions, each spawning 2.5 - 3 http connections.
CPU 3:750Mhz
RAM 8G
Is anybody using multiple JVM for load balance?
What is your ratio of JVM to concurrent iP sessions?
Are you running Apache/Jserv on a server with any other applications, or is Apache by itself?
If you are not using JVM, how many httpd processes do you get before Apache implodes? We stopped in the water at 90 httpd processes, but performance degraded starting at 70 sessions.

Using Web Cache to load balance servlet-based Forms (6i and 9i) is unofficially supported. I say "unofficially" because we have actual customers doing it and getting support, but the 2 development teams (Forms and Web Cache) haven't actually done any integration testing of this sort of configuration yet. For your case, please contact your Support rep and ask what was done to use Web Cache as a load balancer for Forms6i at METRO in Germany. The Forms product managemment team is writing up a white paper to describe how to do it, but until then, you'll need to go through Support. Please contact me if you want more information.

Cluster Apex MS's across multiple nodes for load balancing?

Can Cluster Apex MS's across multiple nodes for load balancing? If Yes/No, any supportive doc's will be much appreciated.
Here is what I did ..........
I tried multiple MS's on different nodes for Apex Domain (clustered)
Deployed apex.war, i.war with targets pointing to cluster.
Apex listener techstack is shared filesystem $HOME/apex, where apex-config.xml and bdb are available
Anyone of the MS's whichever started up first is locking up bdb and 500 server shows up when internal workspace is being launched with host specific url, where as it works fine for the host which actually locked up bdb (first MS that was started)
2nd MS shows errors as below in log files ..
Caused By: com.sleepycat.je.EnvironmentLockedException: (JE 4.0.103)$HOME/apex/bdb The environment cannot be locked for single writer access. ENV_LOCKED: The je.lck file could not be locked. Environment is invalid and must be closed.
Its expected behavior until here .....
++++ I tried something to get it working ++++
Whilst both MS's are up and running, delete $HOME/apex/bdb but let apex-config,xml be as it is...now the internal workspace urls for both hosts work fine. I logged into host specific urls and navigated, created/edited users.,etc and it is all looking good but it did not create new bdb directory under $HOME/apex ...!!
Having said its working fine, the same issue repeats after the MS's bounce. So I did put a command line to delete bdb dir once the MS comes up to avoid the issue but really not sure if this is the right way at all?
Geek's ...awaiting your advice!!

Hey there,
I managed to fulfill my requirement..
If its a cluster on same machine or across machines, this should work
1. Login to machine, cd $DOMAIN_HOME
2. mkdir -p Apex_lsn_config/AdminServer Apex_lsn_config/<MS1> Apex_lsn_config/<MS2> # MS1 and MS2 are the Managed Server names as appropriate
#If you are planning for cluster spawning MS's across machines, make sure you create the dir's on step 2 for each machine respectively. (in my case $DOMAIN_HOME is not shared)
3. Copy apex-config.xml from the /tmp/apex or whatever location you have it currently to Apex_lsn_config/<MS1> Apex_lsn_config/<MS2>
4. cd $DOMAIN_HOME/bin; cp -p SetDomainEnv.sh SetDomainEnv.sh.orig #Backup the file
5. Append -Djava.io.tmpdir in SetDomainEnv.sh as below for JAVA_OPTIONS # Do it on both machine if you are not sharing DOMAIN_HOME and planning cluster across machines
-Djava.io.tmpdir=$DOMAIN_HOME/APEX_CONFIG/${SERVER_NAME}
Hint: Search for "iterativeDev" and append the same line with -Djava.jo.tmpdir
6. Modify "java.io.tmpdir" from the web.xml file of apex.war as below and re-deploy the war
<context-param>
<param-name>config.dir</param-name>
<param-value>${java.io.tmpdir}</param-value>
</context-param>
7. Bounce Weblogic Admin and Manged Servers. Make sure to tail the Managed Server log to see apex-config.xml is picked from the new location.
8. Brew a Coffee for yourself :)
- You find the instructions on creating a cluster from weblogic documentation, the steps mentioned above are only to overcome the bdb locking issue whilst creating a cluster.

Using reverse proxy for load balancing

Hello,
i have succesfully configured a reverse proxy ( Sun Web Server 7 ) to balance load between two application servers ( Sun Application Server 9.1), however i do not want randon assignment of requests using a round robin algorithm ( default option in Sun Web Server 7) but rather i want to apply a 80/20 rule so that one application server will receive 80% of the requests and the other will receive 20%.
Is there a way of performarming such a task.
your help is really appreciated.
thank you

thank you for the reply,
actually i tried it yesterday and it seems to work.
in my reverse proxy settings i added one server two times and the other once and 66% of the requests were forwarded to the first server.
now i have enabled the scenario that you are mentioning above and i so far requests seem to be proceced using the 80% 20% scenario.

Round robin DNS for load balancing between multiple network adapters (Xserve)

I'm attempting to use 'round robin' DNS to load balance between the two ethernet adapters of an Xserve.
Both ethernet adapters are connected to the same LAN and have static IP addresses of 192.168.2.250 and 192.168.2.251.
The DNS zone for the server's local domain/host (macserver.private) has a machine record with both IP addresses (set up in the Lion Server UI).
Having read up on round robin DNS, I would have expected DNS requests for 'macserver.private' to be answered with the two IP addresses ordered at random, achiving my aim of requests being served at random via each ethernet adapter.
However this doesn't seem to be the case. Doing a 'nslookup' from any of the network clients results in the two IP addresses being listed in the same order everytime. And pinging 'macserver.private' only ever results in a response from the same address.
Does anyone know why this is the case? Does Lion Server use a non-standard DNS configuration? Are there any additional settings I need to configure in Lion's DNS server to make adopt a round robin approach to responding to requests?
Thanks in advance for any help!

Be careful what you wish for
Round Robin DNS is rarely the best option for 'load balancing'. At the very least it's subject to caching at various point on the network - even at the client side, once the client looks up the address it will cache that response - this means that subsequent lookups may be served from the client's cache and not refer back to the server. Therfore any given client will always see the same address until the cache expires.
I suspect this is what you're seeing.
You can minimize this by setting a lower TTL on the records. This should result in the response being cached for a shorter period, meaning the client will make more requests to the server, with a higher change of using the 'other' address.
However, you're also going to run into issues with the server having two interfaces/addresses in the same LAN. This isn't recommended.
As Jonathon mentioned, you may be better off just bonding the two interfaces. This will provide an automatic level of dynamic load balancing without the latency of DNS caches, as well as automatic failover should one link fail (as opposed to round robin DNS which will cause 50% of requests to fail until the client cache expires and a new lookup is performed (and, even then, there's still a chance the client will try to use the failed link).

Recommended configuration for load balanced Portal with load balancer, multiple gateways and multiple servers.

Does anyone have a recommended network, hardware and software configuration guide for a Portal installation running with multiple gateways load balanced (ie one URL) that talk to multiple servers?

David,
We've used Resonate (software) to load balance the gateways. It allows
you to group all the gateways under 1 virtual URL and load balance the
incoming connections over each gateway depending on the rules that you
define in Resonate. Look in the SUN portal whitepapers there is one that
talks about it specifically.
As far as load balancing the calls to the portals, the gateways will
automatically load balance across all the portals that they know about
using a simple round-robin rotation. You may be able to use Resonate in
front of the portals but you may need to activate persistance within
Resonate to ensure that the user always ends up on the portal that he
established his initial connection on (if you want that), check with Sun
on this one.

Mod_oc4j for load-balancing

Guys,
Looking for some feedback on DMSMetricCollector when using "metric" as the selectmethod for load-balancing. What i want to know is that whether the DMSMetricCollector can be configured to use multiple metrics such jvm-heapsiize, servlet-processRequestTime etc, Connection-pools FreePoolSize.value etc ? the documentation doesn't explicitly mention that if its possible, apparently it doesn't but want to check from the experts here, Steve you might have something on this...
Or if there is any other implementation available which supports load-balancing based on multiple performance metrics
Thanks and Regards

can i use this loadbalancer.jar or not?

Windows Event Collector - Built-in options for load balancing and high availability ?

Hello,
I have a working collector. config is source initiated, and pushed by GPO.
I would like to deploy a second collector for high availability and load balancing. What are the available options ? I have not found any guidance on TechNet articles.
As a low cost option, is it fine to simply start using DNS round-robin with a common alias for both servers pushed as a collector name through GPO ?
In my GPO Policy, if I individually declare both servers, events are forwarded twice, once for each server. Indeed it does cover high availability, but not really optimized.
Thanks for your help.

Hi,
>>As a low cost option, is it fine to simply start using DNS round-robin with a common alias for both servers pushed as a collector name through GPO ?
Based on the description, we can utilize DNS round robin to distribute workloads and increase fault tolerance. By default, DNS uses round robin to rotate the order of RR data returned in query answers where multiple RRs of the same type exist for a queried
DNS domain name. This feature provides a simple method for load balancing client use of Web servers and other frequently queried multihomed computers. Besides, by default, DNS will perform round-robin rotation for all RR types.
Regarding DNS round robin, the following article can be referred to for more information.

CF8/JRun4 Cluster for Load Balancing

Does anyone have an example of how to set up a CF8/JRun4
cluster for load balancing?
I have three servers:
x004 - Linux - Apache2 (10.0.0.54,10.1.0.54)
x020 - Linux - JRun4/CF8 (10.0.0.70,10.1.0.70)
x021 - Linux - JRun4/CF8 (10.0.0.71,10.1.0.71)
Every server in our network has two network cards. One
network card is attached to 10.0.x.x which has a gateway to the
internet and runs at 100Mbps and is firewalled, and the other is
attached to 10.1.x.x which runs at 1Gbps and is internal with no
gateway. I'm trying to set it up so web traffic arrives on
10.0.0.54 into Apache and mod_jrun20 bootstraps a cluster named
STST using 10.1.0.54 which consists of STST_x020 coldfusion server
running on x020 and STST_x021 running on x021. I want the
communications between JRun4 on x020 and x021 to occur on the
10.1.x.x network and eventhough JRun and ColdFusion will only use
the 10.1.x.x network I still need the 10.0.x.x network card
attached for other purposes which require a gateway. I have
installed JRun4/CF8 about 10 times already and it seems I have no
control over what network JRun4 clusters on... sometimes it will
communicate on one, sometimes the other and without being able to
set which network is being used there always seems to be "network
error" on at least one of the two CF8 servers. I was able to get
everything working fine by disabling the network cards on the
10.0.x.x network and re-installing everything... but as soon as I
added the network cards back the whole thing was broken again.
How is this supposed to work? Most of the examples are either
no clustering or clustering on the same machine with Apache running
on the same box... I don't see any clustering across machines
examples.
How do I install a connector on a web server which doesn't
have JRun on it and get wsconfig to connect to a multi-machine
cluster when wsconfig only accepts a single IP address as a host
and the cluster is not listed?
How do I get JRun to bind to a specific network card?
Does this work if I choose a J2EE server other than JRun?
Any help anyone can provide is greatly appreciated. I'm
getting close to giving up which means staying on the non-clustered
environment and figuring out how we can deal with scalability by
switching to something else.

The article at
http://www.adobe.com/go/1e8e9170
is specific to configuring two or more cluster nodes that reside on
separate networks, e.g. 10.0.1.0/24 and 10.0.2.0/24. (The article
doesn't state it, but you can only use unicast peers if your
cluster nodes host a single instance of JRun or multiple instances
of JRun in the same cluster domain. When performing unicast
discovery, JRun looks for all Jini groups and not just the cluster
group.)
Anyhow, that's not your problem. The simplest solution is you
haven't enabled the jrun.servlet.jrpp.JRunProxyService service. I'm
most familiar with the Windows version of JRun, but I'm assuming
the directory structure is similar across platforms. In
<jrun_root>/servers/<name>/SERVER-INF/jrun.xml, set the
deactivated attribute of the jrun.servlet.jrpp.JRunProxyService
service to false and restart JRun. You should now see JRun
listening on the appropriate port. (The default for the first
manually created instance is 51000.) You can limit the proxy
service to a single interface using the interface attribute.
If you have enabled the proxy service, verify your security
settings in <jrun_root>/lib/security.properties. It's usually
best to limit access to specific hosts. Comment out the
jrun.subnet.restriction parameter and set the jrun.trusted.hosts to
the IP address of your web server, e.g. 10.1.0.54.
Forcing all JRun processes/services to listen on a single
interface isn't difficult, but it does require modifying quite a
few configuration files by hand. If you need assistance with that,
I can elaborate.
Configuring the JRun module under Apache is pretty
straightforward. If you're not using virtual hosts, it's very
simple. If you are using virtual hosts, it's still simple, but your
JRun configuration can be virtual host-specific.
On your Apache server, you'll want to create a directory
structure for the JRun module. I'll assume
/opt/jrun/lib/wsconfig/1, but you can use anything you want. Once
the directory structure is created, extract the appropriate JRun
module from wsconfig.jar to the new directory. You're most likely
interested in the Apache 2.0 module,
wsconfig.jar/connectors/apache/intel-linux/prebuilt/mod_jrun20.so.
Let's assume you've extracted the module to
/opt/jrun/lib/wsconfig/1/mod_jrun20.so. Your Apache service account
should have read, write, and execute permissions on the
/opt/jrun/lib/wsconfig/1 directory.
The JRun module configuration is normally appended to your
current httpd.conf file by wsconfig. Here's a sample configuration:
LoadModule jrun_module
"/opt/jrun/lib/wsconfig/1/mod_jrun20.so"
<IfModule mod_jrun20.c>
JRunConfig Verbose false
JRunConfig Apialloc false
JRunConfig Ssl false
JRunConfig Ignoresuffixmap false
JRunConfig Serverstore
"/opt/jrun/lib/wsconfig/1/jrunserver.store"
JRunConfig Bootstrap 10.1.0.70:51000
#JRunConfig Errorurl <optionally redirect to this URL on
errors>
#JRunConfig ProxyRetryInterval 600
#JRunConfig ConnectTimeout 30
#JRunConfig RecvTimeout 30
#JRunConfig SendTimeout 30
AddHandler jrun-handler .jsp .jws .cfm .cfml .cfc .cfr
.cfswf
</IfModule>
You may also want to update your DirectoryIndex directive
with an appropriate index page, e.g. index.cfm.
After the first request to a page handled by the JRun module
is received, the module will query the boostrap server,
10.1.0.70:51000, for a list of cluster peers. If you've configured
your cluster correctly, a line similar to following will be written
to /opt/jrun/lib/wsconfig/1/jrunserver.store:
proxyservers=10.1.0.70:51000;10.1.0.71:51000
You can create/edit this file manually as well.
Unfortunately, the bootstrap option only accepts one server. If
your bootstrap server is down, the JRun module will use the values
in jrunserver.store directly, if the file exists.
Here's a complete list of JRun module options:
metrics *
debugger *
ssl *
verbose
traceflags
serverstore
bootstrap
errorurl
apialloc
ignoresuffixmap
proxyretryinterval
connecttimeout
recvtimeout
sendtimeout
sslcalist
Options flagged with an asterisk can only be configured at
the Apache server level. All other options can be configured at the
server level and/or the virtual host level. The usage of these
options is in the JRun documentation, and the JRun module source
code is included in wsconfig.jar. Keep in mind that versions of the
JRun module shipped prior to ColdFusion 8 were coded to assign the
connecttimeout and sendtimeout options to the socket connection
timeout. Whichever option appeared last in your configuration ended
up as the final value. This has been fixed in ColdFusion 8 and
presumably the next release of the JRun updater.
I think that's a good start. If you need more information or
can't find what you need in the JRun or ColdFusion documentation,
let me know.
If you're looking for resiliency, I highly recommend
expanding your configuration to include a second web server and a
hardware load-balancer (preferably one that supports redudancy via
multiple paths and devices, e.g. devices from Cisco, F5, or Foundry
Networks). Often, however, running Apache on the ColdFusion
server(s) provides adequate performance, and round-robin DNS
records coupled with the ability to update DNS quickly in the event
of a failure may be all you need for load-balancing and
failover.

Multiple dgraph clustering (load balancing) OOTB available?

Hello,
We have 2 dgraphs running in parallel having the same data to share the load of the clients.
I would like to know if there is any OOTB solution provided by Endeca where in these two dgraphs can share the load. OR I need to use an external load balancer for the same?
If there is any document that explains the configuration for OOTB Endeca solution, please let me know
Thanks!

Hi,
yes I know...
i tried to check if they were still available...but found none,
that's why I said if you want me to send them email me ...(I downloaded them from Eden ) and the files aren't too big

Simple MDEX Load Balancing with Apache HTTP Server
By Robert Dennis
Last Updated: December 2010
Endeca Product Versions: 5.0+
This document describes how to set up a simple load balancing and failover solution using Apache HTTP server. This provides a cost effective mechanism leveraging widely available open source technologies to address simple infrastructure needs. This document includes the following sections:
 Introduction
 Configuration Steps
 References
Endeca Solution Article Simple MDEX Load Balancing with Apache HTTP Server
Endeca Confidential 2 of 5
Introduction
Load balancers are the preferred solution for providing scalability, redundancy, and fail-over for MDEX Engine queries. Typically, load balancing and failover are accomplished with the use of dedicated load balancing hardware. For some Endeca implementations, however, a robust mechanism for load balancing may not be available or required by the customer. For more information on the basics of load balancing an Endeca application, see the “Endeca Load Balancing Best Practices” Solution Article available on EDeN.
This document describes the configuration steps involved in leveraging Apache’s default load balancing mechanisms to provide a simple load balancing solution for an Endeca application. In this scenario, Apache will sit between the Endeca presentation API housed in a web application and redundant MDEX engines. Apache performs the duties of a simple load balancer and failover broker, managing query requests from the application tier to specific MDEX engines.
Configuration Steps
The described configuration leverages Apache 2.2 HTTP Server as the load balancing mechanism between two identical MDEX engines all residing on a single server. The sample configuration expects the Apache HTTP server to be listening on port 5555 and the MDEX engines to be listening on ports 8000 and 8001. These can be changed as appropriate for a given environment.
1. In the Apache httpd.conf, enable the server for listening on port 5555.
Endeca Solution Article Simple MDEX Load Balancing with Apache HTTP Server
Endeca Confidential 3 of 5
2. Enable the following modules by un-commenting the appropriate loadmodule statements in the httpd.conf file. These modules include: mod_proxy, mod_proxy_balancer, mod_proxy_connect, mod_proxy_http, mod_negotiation.
3. Include the httpd-vhosts.conf file by un-commenting the appropriate line in the httpd.conf file.
4. Save the httpd.conf file and open the httpd-vhosts.conf file. Append the below information and save the file.
Endeca Solution Article Simple MDEX Load Balancing with Apache HTTP Server
Endeca Confidential 4 of 5
NameVirtualHost *:5555 <VirtualHost *:5555> ServerName localhost ProxyPass / balancer://dgraphs/ ProxyPassReverse / balancer://dgraphs/ <Proxy balancer://dgraphs> BalancerMember http://localhost:8000 loadfactor=1 retry=0 BalancerMember http://localhost:8001 loadfactor=1 retry=0 </Proxy> </VirtualHost> <Location /balancer-manager> SetHandler balancer-manager </Location>
The “retry” parameter associated with Balance Members disables the period of inactivity for a particular worker after Apache determines it is offline. The default is 60 seconds. It is recommended that this is set to a low number such as 0.
In environments where particular MDEX engines are targeted for additional load, the “loadfactor” parameter associated with Balance Members can be adjusted. Higher values ensure that the load balancing algorithm that is used will route the traffic load accordingly to specific Balance Members.
5. Restart Apache.
6. Within the UI application, configure the host and port of the HttpENEConnection to the host and port of the load balancer (e.g. localhost:5555).
Endeca Solution Article Simple MDEX Load Balancing with Apache HTTP Server
Endeca Confidential 5 of 5
Apache HTTP Server is now properly configured to serve as a load balancer for the MDEX Engines.

Webdispatcher for Load balancing

Hi All,
We have implemented EP7. The portal is configured to redirect to https.
Now we want to use sapwebdispatcher for load balancing.
We are performing the following steps to configure the sapwebdispatcher

1. create profile file "sapwebdisp.pfl"for SAP Web Dispatcher (if not already existing)
2. create user for web based administration in file "icmauth.txt"(if not already exisiting)
3. start SAP Web Dispatcher with the created profile
After the bootstrap you can use the web based administration

Now, if I use any port other than 8101 for HTTP port number for SAP Web Dispatcher the webdispatcher does not work.
If i use port 8101(which i am using currently) then the webdispatcher does the load balancing however i cannot access the http://<hostname>:8101/sap/wdisp/admin/default.html url
Can anyone help me getting both thigs: load balancing and the webdisp admin page also.
Thanks!!

New CAS for Load Balancing Exchange 2007

I want to add a new CAS to an existing Exchange 2007 environment (there is already one CAS and it functions properly) to allow for load balancing. After adding the new server I wanted to do some testing (before I actually set it up for load balancing).
If I try to log in to a mailbox using OWA I get an error stating that "Exception type: Microsoft.Exchange.Data.Storage.ConnectionFailedTransient ExceptionException message: Cannot open mailbox". I am sure I am missing something simple, but cannot
figure it out. Could someone point me in the right direction?

Is your new CAS in the same Windows site as the rest of your Exchange servers? In Exchange 2007 and 2010, the CAS needs to be in the same Windows site as the mailbox it is servicing (unless you are accessing from the Internet and the other site has
no externally accessible CAS).

Using a DI-LB604 load balancing on mac

You can take a look at this thread:

But like I said, if you require more bandwidth per link you need to look at another vendor.

Distributed naming services for load balancing

Can distributed naming services can be used for load balancing?

ata,
Before jumping to anything so bloated and limited as cougaar, take time to consider what you really need. Before grabing at the fanciest Java features like RMI, JINI, and custom SocketFactories; focus on what you are trying to accomplish.
There are plenty of great answers right here, at this forum.
Good hunting,

Clustering for load balancing only

I wish to set up 2 WLS 8.1 machines to run an application independently to
          share load (no replication of sessions, beans etc).
          Can I create a cluster for the two servers and not turn on any session or
          bean replication, then configure the IIS or Apache plug-in to use the
          cluster and therefore create some load balancing?
          Chris


Chris,
          Yes you can certainly use a Cluster simply for load balancing. There is no
          mandate that you have to take advantage of session state replication in the
          cluster.
