OCS 10.1.2.2. on Win2003ServerR2 - Web Cache status "unknown"

Hi, I am experiencing the following:
- When, in EM, I navigate to the Middle tier of my OCS installation, everything looks fine (all processes green and up, including Web Cache).
- If I click on the Web Cache link --> webcache page opens regularly --> web cache icon on top of the page is GREY, status reported as UNKNOWN.
- If from here I click on the "stats" tab, all the stats are reported UNKNOWN and the dropdown menu on top of the page is completely empty, and nothing is selectable.
- If I click on the "Administrative" tab, all the options (e.g. Sites, Origin Servers) are populated correctly.
- last: if I exit from EM and navigate on the webcache administrative page (on port 9400), everything looks fine, and I can successfully start/stop the webcache etc.
It used to work from EM too in the recent past, no changes have been made to the system and the logfiles look OK....... Any clues?
Thanks, Roberto

Hi Andreas,
yes, I tried to restart EM agent... in a matter of fact, I also tried a complete server reboot.
Regarding the XML files, I have been carefully checking targets.xml and webcache.xml and it seems they are allright.... In fact, webcache IS working (if I check it through the administrative tool on port 9400). The whole system runs smooth.......
There must be something strange just with EM configuration....
Can you please tell me a bit more about the various XML files related to EM and Webcache configuration? Maybe I'm missing something....
Thank you
Roberto

No response from web cache server

Hello,
I have OCS installed on linux box. when i am trying to connect to web conferencing home page through winodws, after connectivity check when i click on login, it is showing me error as "NO response from webcache serve".
For webconferencing on linux i have run following scripts ./dcmctl, ./imtctl and ./webcachectl it is showing me as webcached server is running.
what more i have to do for getting the access to webserver?
can anyone help me please?

In the OAS Release 2 Web Cache Admin guide, you''ll find that the solution related to that particular error is to increase the network timeout between the web cache and the origin server. Change it in Resource Limits and Timeouts page of the ASControl.
However, with all the internal errors that you are also getting, the problem is likely something else so increasing the timeout value might only mean it'll take longer before it tells you there's an error.

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: -

Web Cache 'Ping URL' not working.

Hi,
I have recently installed a Webcache clustered pair which sit in front of OHS which reverse proxys back to OUCM/Web Logic, my OWC version is 11.1.1.2 and am looking for some clarification of how the Ping URL actually works in Web Cache.
When OHS is shutdown, Webcache detects the service is down and prevents it from servicing requests, however it will not mark the service as down when I intentionally set ping URL to a page that does not exist generating a 404, will Ping URL polling only mark a server as being down if a 500 error is generated?
Something else I would like clarification of is 'Ping Interval', I have set this to be aggressive at '1' however I do not see any polling traffic or see any hits in OHS log that indicate polling of the Ping URL is taking place.
Thanks in advance,
Mark.

Not sure I need any update to this now, I've just read through the help section 'help/edit_add_appserver.htm' and can see that a 404 is not considered a failure and also that the server only starts to poll when the failover threshold has been reached.
This would explain why the server was not being marked as down, although I'm still not sure why I do not see the polling traffic in Apache logs but I can live with that :)
Cheers,
Mark.

Standalone webcache or Web cache from Oracle Apps Server 10.1.2.0.2?

Hi
I am installing web cache on two servers in web tier and J2EE server (with OHS) on another two servers in apps tier. Should I use standalone webcache or install from Oracle Apps Server package? If I choose Oracle Apps Server package, I have to disable Home, HTTP components. But it is DCM managed. Any suggestions?
And should I deploy my OHS servers on web cache servers in the web tier? In future we want to expand J2EE installation, we will deploy Portal with SSO, OID etc.

Shen Jie,
Please review the Enterprise Deployment to see what are the best architectures.

Cisco Web Caching Solution

Hi There,
I need a high availability web caching solution for 500 users, preferential with proxy funcionality.
Cisco had the Cisco Web Caching Engine, but it is End-of-Sales already. The new product that will replace the EOS product, is Wide Area Application Engine (WAE) plataforms. Is that right?
The Cisco Global Price List has a SKU product SE512-IPROXY-K9 (Security / iProxy WAE-512 bundle, 1GB MEM, 1 250GB HDD Incl.).
The question are:
The SKU product SE512-IPROXY-K9 is the right product for my needs?
What is the difference between the SKU SE512-IPROXY-K9 and the SKU WAE-512-K9?
Regards,
Pedro Vasques

Hi Pedro,
The WAE product line does WAN Optimization which includes HTTP optimization. The WAN Optimization solution works between two WAEs (one being at a Branch office and the other being at Data Center ). When employees at branch office tries to access resources like Servers at Data Center their TCP based traffic gets optimized. For more info pl go to http://www.cisco.com/go/waas
Cisco's Web Caching was a different solution. It caches the web objects when first user goes to a given web site. The following user requests will be served locally as long as cache history is available for that web page.
I suggest you contact either a Cisco partner or Cisco representative in your area.
thanks
Nat

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 !

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
FastE 0/0 (10.250.1.1) ---> connected directly to cache server
FastE0/1 (10.23.1.1) ---> Connected to internal LAN
MultiLink1 (12.x.x.98) ---> 4 T1 multilink to AT&T Internet Service
so here is my config,
ip wccp web-cache redirect-list 46 group-list 40 password webcache
ip wccp version 2

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

Web Cache doesn't work with Oracle Enterprise Manager

In my Oracle 9i Application Server Release 2 since I have changed the administrator and invalidator password in the Web Cache Manager the Web Cache appears as unavailable in the Oracle Enterprise Manager, but it's working!! Any idea?

You have to modify the password manually in OEM's target.xml.

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

An error occurred while starting "Web Cache".

We have corrected the issue. There was something wrong with the files in the WebCache Folder.
Hello,
When starting Web Cache we get the following message:
An error occurred while starting "Web Cache".
WebCache : WebCache - failed to start a managed process after the maximum retry limit
WebCache : WebCacheAdmin - failed to start a managed process after the maximum retry limit
For more information, look at the logs using the related link below.

When we open the event_log in the \webcache\logs folder, there is nothing there. The process is not writing any type of message to the event_log.
We have tried changing port numbers without any success.
This process was working until a restart of the server yesterday. Now Web Cache and Portal are not showing active.
Thank you for any input on this matter.

Try to stop processes that might still occupy the port of the webcache and webcache admin.
Also check the logfiles in the opmn.

ADF application integrating with Oracle Web Cache

Hello,
I am trying to integrated my ADF 11g application with Oracle Web Cache. I used this link http://andrejusb.blogspot.com/2010/06/oracle-webtier-11g-configuration-for.html for it.
I am able to access my ADF application using webcache port 7785.
I created few caching rules in the Oracle Web Cache. And in the popular request section of the Oracle Web cache i see jpg,png and other image files cached.
But the issue is when the application access images like /testapp/test/images/abc.jpg?_adf.ctrl-state=5b0s7lzfo_29 . I created a caching rule with regular expression ^/testapp/test/images/[A-Za-z0-9_]*\.(gif|jpeg|png|jpg)\?_adf\.ctrl-state=[A-Za-z0-9_]*$.
But when i access the popular request in em i don't see the URL given above as cached. The caching reason it specifies as URL contains query string.
I am not sure if i need to do anything additional to cache these URL's as well.
Thanks!
Ram

Yes that works. But my question is how to cache the urls which has querystring. I was trying to give a regular expression to match the url so that the url which contains parameters like _afrLoop which changes with each HTTP request can also be cached.
