Load Balancing Forms Services with an effective healthcheck
I am in the process of configuring two forms 11.1.2 servers running with weblogic 10.3.5 with multiple forms applications clustered across both physical servers. We are looking to load balance to the various forms applications using a hardware load balancer. Can anyone comment on their experience with setting up effective application healthchecks using either hardware or software load balancers?
For example say that we have 3 applications clustered across 2 servers with the following
URLs:
http://server01:7777/forms/frmservlet?config=myapp1
http://server01:7777/forms/frmservlet?config=myapp2
http://server01:7777/forms/frmservlet?config=myapp3
http://server02:7777/forms/frmservlet?config=myapp1
http://server02:7777/forms/frmservlet?config=myapp2
http://server02:7777/forms/frmservlet?config=myapp3
We would need a checking mechanism on the load balancer that could tell if myapp2 was down on say server01 and therefore block traffic to that application yet keep traffic open for the other 2 apps on the same server.
A specific difficulty with forms is that when the database behind the application is down forms services will return an error message within a displayed error form. From the load balancer's point of view the forms services are "up". We need to find a way of detecting that the application is actually available and not just that the forms services themselves are available. To detect that the forms services are available we might normally use the status check:
http://server01:7777/forms/frmservlet?ifcmd=status
however this will only tell use the availability of the forms services on a physical server and not whether any actual applications are available.
I am aware that f5 do a BIGIP offering that includes some Oracle Forms specific components. Can anyone comment on how they have setup Oracle Forms healthchecks using various load balancing methods. In particular if a load balancer is limited to using WGET commands to check HTTP returned content is there a way of checking a forms application's availability and if not how have other people achieved an effective healthcheck?
Many thanks,
Philippe
Did you ever Get this to work?
I am having some problems trying to load balance with Oracle Forms, Discover and reports Oracle Application Server Release 10g (9.0.4.0.2) and I was wondering if you could help. Has any one ever got this to work consistently? We are an ERP product written mostly in forms (904) and are trying to implement are largest customer there performance issue so we need the load balancing to work. Will also accept other recommendation as cost effective as solutions.

FRM-92101: Load Balancing Forms 10g with Webcache
Hi,
I´m having some problems with Oracle Forms and Webcache 10g and I was wondering if you
could help.
Machines: (Pentium IV 2.6 GHz; 2GB RAM; 80GB HD)
A. Red Hat Linux AS 2.1
Oracle AS 10g - Infrastructure Installation
B. Windows 2000 Server - Service Pack 4
Oracle AS 10g - BI and Forms Installation (Using Infrastructure on machine A)
C. Windows 2000 Server - Service Pack 4
Oracle AS 10g - BI and Forms Installation (Using Infrastructure on machine A)
I didn´t apply any Patchsets of Oracle AS 10g. My current version is 9.0.4.0 .
Goal:
Use Oracle Webcache 10g on machine B for Load Balancing an Oracle Forms Application
on machines B and C.
Facts:
The Oracle AS 10g installation on the 3 machines was made without problems.
The Forms Applications are running without problems on both Forms servers in machine B and C.
Symptoms:
I´m getting the following error when I try to access the forms application through Webcache:
FRM-92101: There was a failure in the forms server during startup.
This could happen due to invalid configuration.
Please look in the web-server log file for details.
But, this error happens ONLY when BOTH OC4J_BI_Forms instances (machines B and C) are
running.
When just one of the OC4J_BI_Forms is running everything works fine.
Webcache Configuration:
I´ve followed Metalink note 207668.1: Configuring Web Cache as a Load Balancer for Application Servers
step by step to make the configuration of the following components:
1. Configuration of the origin servers
2. Configuration of Site definitions
3. Configuration of Site to server mapping
After that, I´ve follwed the Metalink note 229900.1: Integrating and using Web Cache with Forms 9i for Load Balancing
step by step to make the configuration of the following components:
4. Session Binding
Then I try to test the Load Balancing and I got the error FRM-92101 when both OC4J_BI_Forms
instance were running.
I´ve searched Metalink and found note 268830.1: Webcache Won't Load Balance 2 Forms Instances.
Following the note instructions I did the following changes:
Added these lines at the end of HTTPD.conf (machine B):
CookieTracking On
CookieName myformscookie1
Added these lines at the end of HTTPD.conf (machine C):
CookieTracking On
CookieName myformscookie2
In Webcache configuration:
I´ve Changed the default session binding from JSESSIONID to "ANY SET COOKIE" for the
site's session binding.
But even after these changes I´m getting FRM-92101 error on the same conditions.
How can I solve this problem ?
Thank you in advance.

Marcus Santos.
([email protected])Just ran into this problem last Tuesday, Nov.30 and applied the changes today.
My configuration is similar to yours: 9.0.4 web cache on machine A, 9.0.4 10gAS forms and reports standalone on machine B and C (not a cluster, no infra).
I appended the Cookie lines you mentioned in httpd.conf located in $ORACLE_HOME/Apache/Apache/conf in both machines B and C.
One important thing you may have missed. After changing httpd.conf in each 9iAS instance, you need to make the change known to dcmctl so issue:
dcmctl updateConfig -ct ohs
Then do the following for each 9iAS instance and it should be ready for webcache:
dcmctl stop
dcmctl start
Setup Any-set-Cookie in webcache instead of JSESSIONID and the whole thing should now work. You can run a form through machine A which will load balance to either machine B or C (which can both be up). Then, try shutting down 9iAS on machine B or C and run a form again. They now all work.

Question about Load Balance SFTP service by using CSS1150X
Does anyone come across of load balancing SFTP service by using CSS1150X? Typically by configuring CSS1150X to load balance FTP service, the configuration will as follow:
content ftp_rule
vip address 192.168.3.6
protocol tcp
port 21
application ftp-control
add service serv1
add service serv2
add service serv3
active
group ftp_group
vip address 192.168.3.6
add service serv1
add service serv2
add service serv3
active
However, for my personal understanding and knowledge, I will configure my CSS1150X as follow to load balance SFTP service:
content sftp_rule
vip address 192.168.3.6
protocol tcp
port 22 //Change 21 to 22
application ftp-control
add service serv1
add service serv2
add service serv3
active
group sftp_group
vip address 192.168.3.6
add service serv1
add service serv2
add service serv3
active
My question is, "application ftp-control" in content "ftp_rule" is still applicable to SFTP or not?I believe application ftp-control would not be used for sftp.
This might cause the session to get dropped when there is no data channel created and cause issues with long connections.
Hope it helps!! -
CSS11501 load-balancing IPv6 services
Hi,
I'm new to content networking and load-balancing.
I am setting up a new nameserver network site and have the following equipment:
- Cisco 2811
- Cicso CSS11501
- Cisco Catalyst 2960
This site will have 2 nameservers which I want to load-balance behind the CSS11501. The network will be setup like this:
Internet
|
Cisco 2811
|
CSS11501
|
Cisco 2960
|
Nameservers 1 & 2
The CSS11501 will be in routed mode and will have a publicly addressed VIP (eg, 203.x.x.x) for the DNS service and the name servers will be privately addressed (eg, 10.x.x.10 & 10.x.x.11). I'm hoping this will work fine and serve the requested IPv4 DNS requests.
I would like the nameservers to also operate on IPv6 and serve out IPv6 DNS requests but am not sure the CSS11501 can perform IPv6 service load-balancing.
My question is, does the CSS11501 support IPv6, load-balancing IPv6 service requests?
Thanks in advance.
Richard.Gilles,
Thanks for the reply.
On another site I was looking at rolling out a Catalyst 6500 CSM module to do the exact same thing as the site I have the CSS11501's at, but it too does not support IPv6 from all I could find. Does the ACE provide all the functionality of the CSM plus IPv6?
Thanks.

Load balancing Reports Services 10g with WebCache?
Hi Guys
Does anybody have any good ideas on how to load balance Oracle Reports Services?
Can I do it with WebCache as with Forms Services?
/Jacob :)My java application resides in a different server (weblogic) from the Oracle Application server (which has the report server). I do a browser redirect from my java application to a URL of OAS . I have hard coded Oracle Application server and report server name in one of my config files in my java weblogic server
In the above URL, servername:7770 is the Oracle Application Server. I would not have a problem with this since this will be the name of the cluster.
But the problem is server=<report server> . The report server which will pickup my request will be identified only after the browser has redirected to the URL. SO I cannot hard code it in my ajava application.
Can I just remove server=<report server name> when generating URL from my java application when I need to run report server in a clustered load balancing environment?
Sorry if my earlier post was confusing -
Load Balancing Forms and Reports with Web Cache
We are planning to add a second OracleAS 10g middle-tier application server to an existing 10g middle-tier.
Both middle tiers will provide Forms and Reports.
Users must pass through two static HTML pages before starting Forms.
We plan to use Web Cache to load-balance (probably using round-robin) between the two middle-tiers.
Does anyone see any problems with this solution?
All comments/suggestions welcome.
Thanks,
JimYou could also load balance the two OC4J's using standard servlet mechanisms. I know that there exists a couple of good notes on Metalink. Go and do a search.

Load Balance Forms and Reports Services
Is it possible to Load Balance an application (written in Developer 9i) between
two computers running Oracle Application Server 10g (9.0.4) Forms and Reports Services ?
If it is possible, can anybody give an example or some kind of documentation, because
the product documentation is not clear.
Thanks in advance...Yes it is possible, but it all depends on what is your definition of load balancing?? Do you mean hardware machine balancing or service availability??? this is a large territory and you have to be specific, you even have the RAC.
Oracle has [Oracle Application Server High Availability |http://download.oracle.com/docs/cd/B14099_19/core.1012/b14003/toc.htm] and metalink Note:740202.1 explains in detail how to configure it.

([email protected])I have more then half decent results with webcache as load balancer, but it still is a round robin (as mentioned before). This means that a session will not be transfered from one application server to the other once the session has been created.
So far I did not discover any benefits of a hardware loadbalancer over webcache, because (here it is again:) you are not able to transfer open sessions from one application server to the next. This has to do with the Oracle Forms architecture. In fact it is still client-server, only with the application server functioning as extra server ;) -
Load Balancing Directory Servers with Access Manager - Simple questions
Hi.
We are in the process of configuring 2 Access Manager instances (servers) accessing the same logical LDAP repository (comprising physically of two Directory Servers working together with Multi-Master Replication configured and tested) For doing this, we are following guide number 819-6258.
The guide uses BigIP load balancer for load balancing the directory servers. However, we intend to use Directory Proxy Server. Since we faced some (unresolved) issues last time that we used DPS, there are some simple questions that I would be very grateful to have answers to:
1. The guide, in section 3.2.10 (To configure Access Manager 1 with the Directory Server load balancer), talks about making changes at 4 places, and replacing the existing entry (hostname and port) with the load balancer's hostname and port (assuming that the load balancer has already been configured). It says that changes need not be made on Access Manager 2 since the LDAPs are in replication, and hence changes will be replicated at all places. However, the guide also states that changes have to be made in two files, namely AMConfig.properties, and the serverconfig.xml file. But these changes will not be reflected on Access Manager 2, since these files are local on each machine.
Question 1. Do changes have to be made in AMConfig.properties and serverconfig.xml files on the other machine hosting Access Manager 2?
Question 2: What is the purpose of putting these values here? Specifically, what is achieved by specifying the Directory server host and port in AMConfig.properties, as well as in serverconfig.xml?
Question 3. In the HTTP console, there is the option of specifying multiple primary LDAP servers, as well as multiple secondary LDAP servers. What is the purpose of these? Are secondary servers attempted when none of the list in the primary list are accessible? Also, if there are multiple entries in the primary server list, are they accessed in a round robin fashion (hereby providing rudimentary load balancing), or are other servers accessed only when the one mentioned first is not reachable etc.?
2. Since I do not have a load balancer setup yet, I tried the following deviation to the above, which, according to me, should have worked. If viewed in the HTTP console, LDAP / Membership / MSISDN and Policy configuration all pointed to the DS on host 1. When I changed all these to point to the directory server on host 2 (and made AMConfig.properties and serverconfig.xml on host 1 point to DS of host 2 as well), things should have worked fine, but apparently Access manager 1 could not be started. Error from Webserver:

In effect, AM on 1 did not start. On rolling back the changes, things again worked like previously.
Will be really grateful for any help / insight / experience on dealing with the above.
Thanks!Update to the above, incase anyone is reading:
We setup a similar setup in Windows, and it worked. Here is a detailed account of what was done:
1. Host 1: Start installer, install automatically, chose Directory server, Directory Administration server, Directory Proxy server, Web server, Access Manager.
All installed, and worked fine. (AMConfig.properties, serverconfig.xml, and the info in LDAP service, all pointed to HOST1:389)
2. Host 2: Start installer, install automatically, chose Directory server, Directory Administration server, Directory Proxy server, Web server, Access Manager.
All installed, and worked fine. (AMConfig.properties, serverconfig.xml, and the info in LDAP service, all pointed to HOST2:389)
3. Host 1: Started replication. Set to Master
4. Host 2: Started replication. Set to Master
5. Host 1: Setup replication agreement to Host 2
6. Host 2: Setup replication agreement to Host 1
7. Initiated the remote replica from Host 1 ----> Host 2
Note that since default installation uses abc.....xyz as the encryption key, setting this to same was not an issue.
9. Started webserver for Host 1 and logged into AM as amadmin.
10. Added Host 2 FQDN in DNS Aliases / Realms
11. Added http://HOST2_FQDN:80 in the Platform server (instance) list.
12. Started Host 2 webserver. Logged in AM on Host 2, things worked fine.
At this stage, note the following:
a) Host 1:
AMConfig.properties file has
com.iplanet.am.directory.host=host1_FQDN
and
com.iplanet.am.directory.port=389
serverconfig.xml has:
<Server name="Server1" host="host1_FQDN" port="389" type="SIMPLE" />
b) Host 2:
AMConfig.properties file has
com.iplanet.am.directory.host=host2_FQDN
and
com.iplanet.am.directory.port=389
serverconfig.xml has:
<Server name="Server1" host="host2_FQDN" port="389" type="SIMPLE" />
c) If one logs into AM, and checks LDAP servers for LDAP / Policy Configuration / Membership etc services, they all contain Host2_FQDN:389 (which makes sense, since replica 2 was initialized from 1)
Returning back to the configuations:
13. On Host 1, login into the Admin server console of the Directory server. Navigate to the DPS, and confgure the following:
a) Network Group
b) LDAP servers
c) Load Balancing
d) Change Group
e) Action on-bind
f) Allow all actions (permit modification / deletion etc.).
g) any other configuations required - Am willing to give detailed steps if someone needs them to help me / themselves! :)
So now, we have DPS configured and running on Host1:489, and distributing load to DS1 and DS2 on a 50:50 basis.
14. Now, log into AM on Host 1, and instead of Host1_fqdn:389 (for DS) in the following places, specify Host1_fqdn:489 (for the DPS)--
LDAP Authentication
MSISDN server
Membership Service
Policy configuation.
Verified that this propagated to the Policy Configuration service and the LDAP authentication service that are already registered with the default organization.
15. Log out of AM. Following the documentation, modify directory.host and directory.port in AMConfig.properties to point to Host 1_FQDN and 489 respectively. Make this change in AMConfig.properties of both Host 1 as well as 2.
16. Edit serverconfig.xml on both hosts, and instead of they pointing to their local directory servers, point both to host1_FQDN:489
17. When you start the webserver, it will refuse to start. Will spew errors such as:

Success!
The server https-host1_FQDN has started up.
The server infact, didn't start up (nothing even listening on 58080).
However, if AMConfig.properties is left as it originally was, and only serverconfig.xml files were changed as mentioned above, web servers started fine, and things worked all okay. (Alright, except for some glitches when viewed in /amconsole. If /amserver/console is accessed, all is good. Can this mean that all is still not well? I am not sure).
So far so good. Now comes the sad part. When the same is done on Solaris 9, things dont work. You continue to get the above error, OR the following error, and the web server will refuse to start:
Differences in Solaris and Windows are as follows:
1. Windows hosts have 1 IP and hostname. Solaris hosts have 3 IPs and hostnames (for DS, DPS, and webserver).
No other difference from an architectural perspective.
Any help / insight on why the above is not working (and why the hell does the documentation seem so sketchy / insecure / incorrect).
Thanks a bunch! -
Using Web Cache to Load balance Forms Server application.
Hello,
I apologize for cross posting this question in the Forms and Caching Services forum. But I thought my question will have a better chance.
I have read that it's possible to use Oracle Web Cache as a software load balancer between multiple Application Servers.
We are running Oracle9iAS R1.0.2.2.2a, with Forms/Reports6i servers on 2 Win2k boxes i.e our Forms6i application is deployed on two seperate boxes in two distinct locations. Users at each location, use their respective App Server url.
Since the application is the same i.e. Forms6i code/fmx is the same for both locations, I am looking into loadbalancing and failover capability that Web Cache might be able to provide.
I AM ONLY LOOKING AT THE LOADBALANCING & FAILOVER capabilities and NOT caching.
So basically all users from both locations will point their browser to this Web Cache and the Web Cache will direct each connection to either of the two boxes. So, if either of the boxes dies, Web Cache will divert the requests to the other box.
My concern is whether Web Cache supports this for the Forms requests that it will receive from the users. We are using Servlet Deployment of Forms, so technically, all communication is going though the HTTPD.
Has anyone done this or has any ideas as to whether it's going to work or not? Oracle's FAQ insists that Forms is not supported. But I want to make sure that even loadbalancing is not supported. And if not supported then is there any other solution.
Any comments appreciated.
Thanks,
ManishUsing 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.

Oracle RAC load balancing advisory services query
Hi,
I have a query on RAC load balancing advisory.
Is it possible to create a service for exeuction of a PL/SQL package?
We have UNIX batches which are set of PL/SQL packages that may or may not be linked are executed daily. These batches consumes lots of resources.
So i want to configure my services such that say pkg1 will go to node1 and pkg2 will go to node2 and so on and so forth.
Is it possible to achieve this with Net services and LBA?
If not, is there any other way i can do this?
Thanks

Amit TrivediHi, my answers are:
Is it possible to create a service for exeuction of a PL/SQL package?Yes, that is posible, you can create a service for execute PL/SQL Packages, in fact you can create any service that you need and assign the resources and priorities for this service.
Is it possible to achieve this with Net services and LBA?Yes, thats posible, you define the priorities at service level and where the service must run at node level.
If not, is there any other way i can do this?Yes, if you dont wish using the LBA and services you will must create statict definition into tnsnames file for operate connection string and indicate where must connect the session for execute the package.
Luck.
Have a good day.

Load Balance HTTPS servers with redirection
Hello,
I have been tasked with ACE configuration at work as the prior go-to guy for load balancing is no longer available. Trouble is, I have little idea what I’m doing when it comes to the ACE. So, forgive me if the question I have is super basic. After doing some research I put together a LB config, but its not working.
I was trying to load balance 10 servers, split into groups of 2 using 5 VIPS (1 VIP for each group of 2 servers). The servers serve an ssl web app.
Below is my configuration. What am I doing wrong? Does the config have any glaring errors? I've been staring at this thing on and off for a week and searching these forums trying to figure it out.
Any help provided will greatly appreciated.

Thank you so much for your reply.
At this point I can get to the real server IP's via ping and https in a browser from my PC. I can also ping the gateway and all the real server IP's from the ACE context i'm working on. However, the VIPS are not working. When I attempt to use one of the VIPS in the browser, the request times out. When I issue the command ":show service-policy" I see a hit count (which increments every time I try and reach the VIP via the browser) but the dropped counter is equal to the hit counter. I will paste the running config from the context I’m working in along with the output from the show service-policy command.
Any suggestions on how I can get this working would be greatly appreciated.

Load Balancing - Forms Metrics Server
Hi everyone, i have a doubt, for implemeting Load Balancing with Forms Metrics Server previous i must have configured Shared APPL TOP?
And for Load Balancing JServ also i must have configured Shared APPL TOP in all my applications servers?
Thank you very much for helpingIt is not a must, but it is recommended. If you are planning to configure PCP then it is a must.

OSB 10gR3 - Create load balanced endpoint URI with WLST
Hi,
I need to create load balanced endpoint URIs for a Business Service listening to a JMQ queue. The configuration can be done through the console as shown below:
Protocol: JMS
Load Balancing Algorithm: round-robin
URI 1 - jms://localhost:7001/loggingXACF/loggingQueue
URI 2 - jms://localhost:7002/loggingXACF/loggingQueue
I would like to do the same using ALSB customization API in WLST. Any pointers on this would be helpful
Regards
VikasAny one have any idea what a CLUSTER-BROADCAST message is? And where it would be coming from?Cluster broadcast message is one of the way by using which WebLogic Server instances in a cluster communicate with one another. Details are here -
http://download.oracle.com/docs/cd/E14571_01/web.1111/e13709/features.htm#i1021836
Having little idea about this, I may not comment on the exact reason behind 21.4 million CLUSTER-BROADCAST messages in 70 minutes, but you may get better and faster response in Weblogic clustering forum -
WebLogic Server - Clustering
If you have Oracle Support, then I will suggest you to track this throgh a SR.
