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.

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: -

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.

Taking old report even new report is uploaded on web - Cache problem?

Hello,
I have a problem. We are using remote server for development work.
We are working on web environment. The modules (forms & reports) will be uploaded to the unix server using web compilation links. Now I haveI uploaded (generate), a report (old) to the server. After some modifications new report is uploaded . When I run the report, it is always taking old one, instead of new.
Time stamp in the server is showing new one is uploaded.
I heard this could be because of cache problem on the server. If some one have faced the same , please let me know the solution for this?
Cheers
Ram Kanala

FRM-40738 (repid is coming out null)
Looks like here it is not able to find the report
repid := find_report_object('ETOX_9ITEST');
In Forms builder confirm that you have defined a report by this name for the particular form (adding the report in REPORTS_PATH would not suffice). I think it should also point to corresponding report.
Please post the exact error messages as you see it with the error numbers.
Other comments.
2) Added a TNS_ADMIN in the registry to point to TNSNAMES.ORA in the apps directory. This Tnsnames.ora has an entry for report server name. The report server is up when seen in OEM console. But my report does not launch. <<For 9i you do not need to do this . This alias defining is for 6i. In 9i it is "auto discovery" in the subnet.
You can remove this. (You need Tnsnames.ora for DB aliases, I am talking about reports server...)
3) Same comment as above
8)Verify the Reports 9i Service properties and check the "Log On as" information. Be sure to specify on "This account" the user information with which the installation was made.
For Windows/2000:
- Start-> Settings-> Control Panel-> Administrative Tools-> Services
- Double click on the Reports Server
- Go to "Log On" tab
- Change on the "Log On As" section to "This account" and enter the userid/password of the
user that installed Reports Server
- Ensure that the user account where the Reports Server is installed has administrator privileges
and a default printer.
- Restart the Reports Server as the new user.
(For WinNT steps will be similar)
---Workaround till your issue is solved is ....
Start report server as a standalone server
rwserver server=server_name
Thanks

I am facing a caching problem in the Web-Application that I've developed us

Dear Friends,
I am facing a caching problem in the Web-Application that I've developed using Java/JSP/Servlet.
Problem Description: In this application when a hyperlink is clicked it is supposed to go the Handling Servlet and then servlet will fetch the data (using DAO layer) and will store in the session. After this the servlet will forward the request to the view JSP to present the data. The JSP access the object stored in the session and displays the data.
However, when the link is clicked second time then the request is not received by our servlet and the cached(prev data) page is shown. If we refresh the page then request come to the servlet and we get correct data. But as you will also agree that we don't want the users to refresh the page again and again to get the updated data.
We've included these lines in JSPs also but it does no good:
<%
response.setHeader("Expires", "0");
response.setHeader("Cache-Control" ,"no-cache, must-revalidate");
response.setHeader("Pragma", "no-cache");
response.setHeader("Cache-Control","no-store");
%>
Request you to please give a solution for the same.
Thanks & Regards,
Mohan

However, when the link is clicked second time then the request is not received by our servlet Impossible mate.. can you show your code. You sure there are no javascript errors ?
Why dont you just remove your object from the session after displaying the data from it and see if your page "automatically" hits the servlet when the link is clicked.
cheers..

Web cache starting problem (Oracle 9iAS)

Hi, newly I installed Oracle9iAS for portal development.
The problem I am having now is:
When I tried to start the web cache service in ias lever,
it always gives me the following error:
oracle.sysman.emSDK.util.jdk.EMException: Throwable: The attempt to start or stop Web Cache failed
Please help em on this issue. Any advice will be greatly appreciated.

I suggest that you post this question in the OracleAS Portal Caching forum:

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

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

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.

Wccp web-cache -- can't get it working

I installed a Squid based caching appliance, by Stratacache. it supports GRE wccp redirect in transparent mode, I have it configured as wccpv2 using the Router's LAN ip address 10.250.1.2.
Every time I turn on the caching for a host (or the entire LAN) the internet breaks for whomever I turn wccp on. I have tried disabling CEF and have moved the cache to it's own router interface.
Topology of the Cisco 2801-SEC-K9 router, running 12.4(22)T advsecurity

So I can see the packets redirected, the cache never sees them, the router and cache can ping each other, the cache and LAN clients can ping each other - am I missing something?

so I found the problem... hopefully this helps somebody else in the future... the problem is the redirected packets were sourced from the router multilink1 interface IP address and the cache was expecting them from the router fa0/0 interface, so it dropped them.
also the cache has a "spoof client IP" option that was on, because we prefer to do this for netflow, but, I don't think client-IP-spoofing works with the standard web-cache wccp service. It was causing internet problems so I turned the spoofing off and it works fine...
hope this helps
