Problem in web cache cluster in 10.1.2.3

Hi,
I'm using webcache clustering in Oracle AS 10.1.2. and there are 3 cluster members.
But all the requests are getting routed through cluster member 1. When i'm bringing down services(HTTP, webcache,webcache admin) of member1 i'm unable yto access my website.
when member_1 is working, i'm able to access site from all 3 web servers through both web cache http listener port and OHS listener port.
Help !

I understand this is not an EBS related question, so please post your question in the appropriate forum for a better/faster reply -- https://forums.oracle.com/forums/category.jspa?categoryID=13
Thanks,

Problem configuring Web Cache component on RHEL5 64bit in oracle VM

I trust that someone can help with the following:
1. During the install of 10.2.0.3 Oracle Enterprise Manager Grid on Red Hat Linux Enterprise 5, and I continue to get an error with configuring Web Cache component.
Thanks in advance

hi,
I dont think any one will be able to help you if yo post so much brief question. Can you please paste
1) exact and complete error mssage
2) how much installation is complete and at which stage your installer is right now.
3) Did you try to look at the installation log from oracle inventory location? You should also be able to see some clue over there
Thanks

Session Binding on Web Cache acting as load balancer

Hi gurus,
I have Web Cache 10.1.2 acting as load balancer on the front-end machine, and two OracleAS 10.1.2 enterprise edition installations behind it. The load balancing configuration is done and is working well. The Web Cache (acting as load balancer) routes requests the to the two OracleAS installations very well.
Now I need to set up session binding, so that a request from the same client is directed to the same OracleAS installation (in the same session). I am really a novice on session binding - could you pl let me know what I need to do?
Going through the Web cache admin guide, I did try to use JSESSIONID but without much success. Specific Qs:
1. Do I need to enable session binding at only the back-end OracleAS installations, or also at the front-end Web Cache (acting as load balancer).
2. If I use JSESSIONID - is it generated by Web Cache / HTTP Server automatically, or do I need to write a J2EE application to generate it?
Thanks a lot in advance.

Oracle9iAS Web Cache for PL/SQL ????????

Hi,
I installed Oracle9iAS Web Cache.
I could cache any web site which write by asp, jsb,... but I can not cache web site http://www.vnn.vn because it write by pl/sql.
How do I cache web site which write by pl/sql, ex that web site.
Please, give me email follow address : [email protected]
Thanks
Nguyen Tien Dat

You should have no problem using Web Cache to accelerate a PL/SQL driven site. Any site that delivers content via HTTP is a good candidate for Web Cache. Try downloading the standalone Web Cache software from OTN, and be sure to read the manual to learn about how it works and how to configure it.

Setting OF LD_LIBRARY_PATH AND WEB CACHE PROBLEM [SHOWING PREVIOUS PAGE ]

Dear Members,
I would request for help regarding setting of LD_LIBRARY_PATH in Oracle 11G Application server and web cache problem when any single text file edit and save the result should not be changed . it shows previous page result.
*1. Where to set LD_LIBRARY_PATH in Oracle11g Application Server (10.3.0) ? [ like in 9ias we set in opmn.xml . ] Where is opmn.xml file in oracle11g or which files contained LD_LIBRARY_PATH?*
*2. When we created program generated report it shows correct result after some changes in file and generate again it shows first means previous page result as it is not take changes in that file. Even we tried out side made one .text file and open edit and save. It's given same result. So What is the problem regarding it?*
It is the matter of Browser Cache or WEB Cache. Where is the settings of it?
*3. How to connect database (oracle11g Release 2) through OCI driver?*
Regards
Vipul Patel

If you're compiling it yourself, you should set the library path then. If not, you can try something like this:
env DYLD_LIBRARY_PATH=$DYLD_LIBRARY_PATH:/path/to/add-on-libraries orca ...
but I'm not sure it will work.

Web cache problem

hello all.
I am working with OCS 9.0.4.1.1 I installed it in 2 systems. When i am trying to work with oracle file sync( to copy files from my computer to my private file location) while syncing,suddenly it showed an error. Till then an error is occuring while loging as the end user in the middle tier(SSO loggin).i.e, WWC-40019 WebCache error. I checked the service it is up and running . I de-installed all and i installed it again, even also i got the same problem. Why it is happening and how i can solve that error. Please help me . Thanks in advance.

kumaraswamy.N

OK, sorry for the delay in getting to this one.
The reason you're all seeing these problems is that the default behaviour for Database provider component caching has changed between release 1 and release 2.
You can check this by adding &_debug=1 to the URL you're working with in the browser.
The default component cache value for that type of object is set on the first tab in the box marked 'Expire After (minutes)'
By default this is set to 0 (zero), in release 1.x of portal this meant - do not cache ever. In r2 of portal there is no option to not cache, therefore a zero value actually equates to 86,400 seconds.
The lowest value you can have is 1, which equates to a cache retention period of 60 seconds
Even if the page is set to 'Do Not Cache' the portlet content (in this case will be cached for the time specified in the 'Expire After' setting.
So, if you change these values to 1 you should start to see your changes, if you would like to check the cache retention values and whether an object is cached or not, add &_debug=1 to the URL string in the browser
You will see the following types of information under each portlet..
Information for Portlet 33,31211
Portlet Timing: 14 msecs (wait=66)
Timing Status:
XSLT Timing: null msecs
Caching information of portlet:
Portlet Cache status: Web Cache:- HIT [H]
From Cache: Web Cache:- Cache Expires: 86400 secs, Age in Cache: 61 secs
From Portlet: -

Problems with invalidating web cache

Currently we display the current date (portal smart link) in the top region of each portal page. We have been having problems with the date not refreshing, rather old pages continue to be served up. I set up a database job using wvuxtil to send an XML document to invalidate all documents in the web cache under root at midnight. (The caching of every portal page is set to "content and definiton at system level" for 1440 min). This morning, the job ran but when checking the pages from a client machine, the date still displayed as yesterday's for SOME of the pages (not all)- clearing the clients IE cache made no difference. Logging on to the server, I accessed the relevant pages displaying yesterday's date on the client - and they showed the correct date on the server. Going back to the client machine, the dates are now correct ? Help anyone ? What should I be checking/looking at next ?
Cheers
Brent Harlow

Hi Brent,
Which version of Web Cache and Portal are you using? A similar problem with dates and invalidation has been reported before, so you may want to check with Oracle Support for the appropriate patch.

Problem in using OracleAS Web Cache as Load Balancer

I have two machines:
aimssrv.world.com and aimsrep.world.com.
Both of above machines are running Redhat Linux AS 4.
On both machines, I have installed Oracle Forms and Reports 10g Services. I have deployed my application on both machines.
I am able to access my application at aimssrv.world.com by doing:
http://aimssrv.world.com:7778/forms/frmservlet?config=aims
and I am also able to access my application at aimsrep.world.com by doing:
http://aimsrep.world.com:7778/forms/frmservlet?config=aims
I have implemented OracleAS Web Cache at machine aimssrv.world.com, and have enabled the Load Balancing.
In Origin Servers, its showing me two servers:
Host => aimssrv.world.com, PORT=> 7778, Routing=> Enabled, CAPACITY=>100, Failover Threshold=>5, PING URL=>/, PROTOCOL=>HTTP
Host => aimsrep.world.com, PORT=> 7778, Routing=> Enabled, CAPACITY=>100, Failover Threshold=>5, PING URL=>/, PROTOCOL=>HTTP
In Site Definition, I have following information:
Host Name=> aimssrv.world.com, PORT=>7777
In site-to-server mapping, I have following information:
Priority      Host Name      Port      ESI Content Policy      Host Name      Port      Proxy
1      aimssrv.world.com      7777      Unrestricted      aimssrv.world.com      7778      No
aimsrep.world.com      7778                                    No
2      *      7777           Exclude Fragments      aimssrv.world.com      7778      No
3      *      *           Exclude Fragments      aimssrv.world.com      7778      No
In Session Binding, I have selected "JSESSIONID" as session, and "OC4J-based" as session binding mechanism.
Now please guide me as how would I run my application by using the OracleAS Web Cache?
What would be the URL?
Do I need to make any changes in httpd.conf files of aimssrv.world.com and aimsrep.awc.com?
Please guide.
Thanks and regards

hi,
i hv recently configured webcache load-balancing for my 2 mid-tiers.I did not upgrade pre-requisite webcache upgrade patch 4569559 to my 10g rel 2 10.1.2.0.2 OAS and it still worked a bit but I do have some doubts why oracle recommends installing this patch before configuring webcache load-balancing.Have u?
btw u need to collapse all the features of webcache of caching to turn on http load-balancing.U need to add a parameter to internal.xml (LOADBALANCE ON="YES") and register origin servers of both servers with each other and map ur sites so that origin servers of both servers will cater sites of server1 and server2 at the same time.
what worked for me is i registered origin server of server1 at server2 and origin server of server2 at server1 and mapped site of server1 (http://server1:port/forms/frmservlet?config=something) to work with origin server of server2 as well at site-to-server page so that origin servers of both servers will load-balance my server1 site and vice-versa.
But still its not seamless.The initial site request was still being routed to the server which is DOWN first and not seamlessly routed to other server which is UP.Maybe webcache upgrade patch would hv done this seamlessly????

Iip web-cache redirect command problem

Hello,
There is sample in : http://www.cisco.com/univercd/cc/td/doc/product/lan/c3550/12112cea/3550scg/swwccp.htm
Fast Ethernet interfaces 0/2 to 0/5 are connected to the clients and they are configure as :ip wccp web-cache redirect in .And Fast Ethernet interface 0/1 is connected to the cache engine and it does not configure as : ip wccp web-cache redirect out.
in : http://www.cisco.com/univercd/cc/td/doc/product/software/ios121/121cgcr/fun_c/fcprt3/fcd305.htm
The sample in this doc is configure as :ip wccp web-cache redirect out.
I want to know the different of :ip wccp web-cahe redirect out and ip wccp web-cache redirect in. And in which condition I shall use ip wccp web-cache redirect out and in which condition I shall use ip wccp web-cache redirect in ?

Sir,
The ip web-cache redirect in command is only a new addition in the late 12.1 and 12.2 train of IOS. Both commands do the same thing except the redirect in is on the interface where client sourced traffic enters the router and the redirect out is on the interface interface of the router. You do no use both at the same time.
My preference is for redirect in as the router does not need to route the packet because wccp picks the packet up on the incomming interface.
Cheers
Phil

Problem Configuring the Web Cache Sample Provider

I am trying to install the web cache sample provider. The instructions indicate that the web cache user name and password need to be obfuscated.
When I execute the following command from Windows Command Prompt:
C:\oc4jext\jdk\bin>java -classpath c"\oc4jext\portal\jlib\pdkjava.jar oracle.webdb.provider.v2.cache.Obfuscate username:password
I get
java.lang.ClassNotfoundException: oracle.security.misc.Checksum
The installation instructions indicate that the command should work if the pdkjava.jar and the jawc.jar files are in the correct directories. Both are in the correct directories.
I've searched for the missing Checksum class but have not been able to find it in the version of oc4j that I am running. I am running a pre-configured version of oc4j, referred to as oc4j_extended. It is version 9.0.4.0.0 build 031125.1647.
Any help would be much appreciated.

Can you add the $JDEV_HOME/jlib/ojmisc.jar file to the classpath as well? This is the one that contains the Checksum class.

IE browser and Web Cache and SSL - Internet Explorer cannot display the web page

When using IE8, IE9, or IE10 with Web Cache and SSL certain pages which display a lot of data returns the error - "Internet Explorer cannot display the web page."
if we eliminate SSL but continue to use Web Cache, the error does *not* reproduce & If we eliminate Web Cache altogether the error again does *not* reproduce. The error is only reproducible when we use SSL with Web Cache and if we use IE and we access *large* pages. The error is not reproducible with Firefox or Chrome. This is a Web Tier 11.1.1.7 installation with WebLogic 10.3.6 & Red Hat Enterprise 5 Linux x86-64

Hello ,
Try Below Workarounds:
Workaround 1:
Open Central Admin
àApplication Management à
Configure Alternate access mapping-->Edit your web application zone and add your server name in Intranet zone. So default can be serverIP and intranet could be servername.
Workaround 2:
Might be there is some issue with DNS and try to check that WebApplication is pointing to correct IP or not.
Also try to access your Sharepoint site using ip Address .. If you still gets error Kindly share the logs ..
Best

Cache.cluster.multicast.ip and Installing Oracle Identity Analytics

After following the configuration steps outlined below, and deploying the war to Glassfish, I get an error starting RBACX that I think must be related to the cache.cluster.multicast.ip property settings below (error log follows the configuration step outlined next):
7.Make the following changes if there are multiple instances of Oracle Identity Analytics, standalone or clustered, on the same subnet.
a.Navigate to rbacx_staging/WEB-INF directory.
b.In a text editor, open application-context.xml, find bean id commManager, and examine the constructor-arg value.
c.Set the constructor-arg value with a unique instance name, e.g. value="SRM-Instance-1".
d.In a text editor, open search-context.xml, find bean id searchConfiguration, and examine the constructor-arg value.
•The deployment is a standalone, constructor-arg defaults to a value of 0, which is specified as value="0".
e.Navigate to rbacx_staging/WEB-INF/classes directory and do the following:
i.In a text editor, open oscache.properties (located in the rbacx_staging/WEB-INF/classes directory), and find the cache.cluster.multicast.ip property.
ii.Uncomment cache.cluster.multicast.ip by removing the # at the start of the line. Each Oracle Identity Analytics instance requires a unique cache.cluster.multicast.ip value.

Did you import all the relevant sql scripts for your database? You have to import all the migrate/upgrade scripts as well. Once you have imported all the required sql scripts, it will start properly. You can ignore the cluster warnings.

FRM-92101: Load Balancing Forms 10g with Web Cache

Hi,
IÂ´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 didnÂ´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:
IÂ´m getting the following error when I try to acces 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:
IÂ´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, IÂ´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.
IÂ´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:
IÂ´ve Changed the default session binding from JSESSIONID to "ANY SET COOKIE" for the
site's session binding.
But even after these changes IÂ´m getting FRM-92101 error on the same conditions.
How can I solve this problem ?
Thank you in advance.
Marcus Santos.

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.
HTH,
Raffy
