Web Cache Acess.log Size

Hi all,
Windows 2000 Server
Oracle Application Server 10G
Web Cache 9.0.4.0.0
access.log of web cache is big (500MB).
is there any way to keep this file smaller ? kind of rotate logs ?
if i want to analyze this file i have to load 500MB into notepad :(
is there anything like UNIX "tail" in windows world ???

Please check the event log settings namely 'flush interval'. Set this to be very small or diable buffering. Now check it. One possibility is that the event log's size is too small (say it has only 1 or 2 lines in it) to rollover. Also, try restarting Web cache and admin servers and try again.

Web cache log analyzer

Hello to all
I spend too many time searching for a software for oracle web cache's log analyzer without any good answer, my question is, is it really impossible to analyze the file event_log generated by oracle web cache?
Thanks for reading this, specially if you give me an answer ;)

Oracle provides some "Portal Performance scripts" to sql*load the logs into a schema and then get some figures with seeded views. You can adapt to what you need.

Web Cache Error

We are occassionally getting the following error in various scenarios -- in development or just browsing the site:
"Oracle Web Cache Network Error"
Oracle Web Cache encountered a network error when communicating with the application web server.
We have Web Cache installed on the same server as the portal application, but an Oracle consultant who was in a few weeks ago said we had more than enough capacity. Any ideas? We're on Oracle Portal Version: 3.0.9.8.2 and

The error you are seeing is usually the result of a slow response from your origin server, although it could be something else. If you provide
a snippet of your Web Cache event log (verbose), I'll be able to assist you better.
For now, let's assume it is due to a slow origin server response. On a cache miss, if the Web Cache doesn't receive a response
from the origin server within a given time interval, it will close the connection with the origin server and respond to the browser with
a network apology page. This is the page you are seeing. There are ways to correct this.
First of all, you should modify the network apology page in order to customize it for your application or web site. The file is located in the $ORACLE_HOME/webcache/docs directory.
If you're using Web Cache 9.0.2.x, the default origin server timeout is 3600 seconds. You probably won't have to change this, but if you want to, then
please refer to the "Oracle9iAS Web Cache v9.0.2.0 Administration and Deployment Guide", available on OTN.
The relevant section is" Chapter 6, Task 7: Configure Network Timeouts."
If you're running Web Cache 2.0.0.x, the default origin server response timeout is 30 seconds. This default was chosen because we felt
that no application should take more than 30 seconds to respond to a user's request. Since then, we've learned that a lot of apps out there,
especially business intelligence apps, have complex queries that take several minutes, if not hours, to complete. To change this default timeout, you need to modify your internal.xml
file. Here's a snippet from the 2.0.0.4 readme.html file describing how to do this:
3.0 Network Apology Pages
When Oracle Web Cache sends requests to an application Web server, Oracle Web Cache permits the application Web server 30 seconds in which to
generate a response for the browser. If the application is unable to generate a response within that time, Oracle Web Cache sends a network apology
page to the browser.
If 30 seconds is not sufficient, then you can change the default settings of the OSSEND_TIMEOUT and OSRECV_TIMEOUT attributes in the
internal.xml file:
OSSEND_TIMEOUT: Network round-trip time (latency) between Oracle Web Cache and the application Web server. The 20 second default of
the OSSEND_TIMEOUT attribute is usually sufficient for most operating systems.
You can determine the latency to the application Web server by issuing the the following command from the Oracle Web Cache computer:
ping -s application_Web_server
This command provides output similar to the following:
PING sales.us.acme.com: 56 data bytes
64 bytes from sales.us.acme.com (130.35.45.34): icmp_seq=0. time=20. ms
64 bytes from sales.us.acme.com (130.35.45.34): icmp_seq=0. time=21. ms
If the time value is over 20 seconds, then increase the OSSEND_TIMEOUT attribute value.
OSRECV_TIMEOUT: Latency and application Web server processing time. The default is 30 seconds.
You can determine the processing time by sending a sample request to the application Web server and monitoring the time to process the
request. If the processing time is over 30 seconds, then increase the OSRECV_TIMEOUT attribute value.
To change these default settings:
1.Locate the following line in the internal.xml file:
<CALYPSONETINFO/>
2.Modify the <CALYPSONETINFO/> line as follows:
Add the OSSEND_TIMEOUT attribute as follows:
<CALYPSONETINFO OSSEND_TIMEOUT="seconds"/>
Add the OSSRECV_TIMEOUT attribute as follows:
<CALYPSONETINFO OSSRECV_TIMEOUT="seconds"/>
Add both the OSSEND_TIMEOUT and OSSRECV_TIMEOUT attributes as follows:
<CALYPSONETINFO OSSEND_TIMEOUT="time" OSRECV_TIMEOUT="time"/>

Im guessing its Ciscos own format.

No response message from web cache

Hi,
We are facing a strange and serious problem with our Oracle infrastructure. We have running a web application that uploads files to the database server. But we have found out that if we try to upload a ZIP file (in the application, uploading a ZIP file means that it uncompresses the ZIP file and copy the zipped files one by one to the database server, therefore this operation can take a while), it comes an error message of the type:
No Response from Application Web Server
We didn't find any especial configuration for a timeout in the application server and http server. We also checked the timeout for the web cache that we also use, and seems to be alright (very much longer that the time to crash). When using the application without going through the Web Cache (calling directly the application server), it works well!!! On the other hand, we thought in a relation between the size of the files and the effort of the application to process them and the "No response", but we have successfully uploaded other documents bigger than the ZIP file. When checking the LOG files of the Web Cache and the Apache and application server, we find the following:

Could it be that the Web Cache sent a request to the application server and because of an unknown reason, it received a response that made it to show the "No response" message. Or could it be that the Web Cache is sending request and not receiving any response from the application server, or that there is some timeout configuration that we didn't find??? Please, help!!!!
Thanks in advance,
Luis

We found the core issues was with the number of database connections that were created during load testing. Refactoring the code to reuse the database connections fixed this issue.
Thanks,

Web cache crash after serving first request from Mozilla browser

Observing this with version 2.0.0.0.0 of the web cache. The first request from a Mozilla browser is successfully responded to - snoop output shows html delivered correctly in response to the GET. Immediately after that request is satisfied, the webcached is not running, with no core file or mention in event_log as to what could be wrong even in verbose mode -- last mention in the event log is "cache inserted one file '/foo.html' in bucket 47630".
The problem occurs even with default cacheability rules- changing expiration rules seems to make no difference.

There were some problems with the 2.0.0.0.0 version with regard to the size of response headers. Please download the 9.0.2.0.0 version and see if that fixes the problem. This is the version you should be evaluating anyway. 2.0.0.0.x is over a year old now and 9.0.2.0.0 has undergone more testing and trial deployments than in previous releases.

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.

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
Event_log shows below errors.

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 ..

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.
Related Link Error Logs
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.

Need help resolving Web Cache upgrading error

I successfully installed 10g AS on top of my 9i AS (9.0.3) on a different Oracle home. Then I proceeded to run the Upgrade Assistant (iasua.bat). Everything went well except the upgrade of Web Cache failed. I'm only installing/upgradeing the J2EE and Web Cache. Any help would be greatly appreciated.
I'm running on XP SP2.
the following are the lines in iasua.log related to the error:
2007/04/04 21:10:22.890 GMT NOTIFICATION:1 Framework: Starting to upgrade WebCache.
2007/04/04 21:10:23.515 GMT ERROR:1 WebCache: Invalid element 'MULTIVERSIONHEADERSRULE' in content of 'CACHEABILITYRULE', expected elements '[SELECTORS]'.
2007/04/04 21:10:23.515 GMT ERROR:1 WebCache: Unable to upgrade file C:\Oracle\ora9ias\webcache\webcache.xml
2007/04/04 21:10:23.515 GMT NOTIFICATION:1 Framework: Finished upgrading WebCache with status: Failure.

What that means is Silverlight can't find a required component.
When I clicked on the site, it loaded pretty slow but I got to see the login screen without error.
Either the expected dll is cached on my machine or you have an intermittent problem.
As I'm a some-time Silverlight developer I could well have necessary dll if they are standard components.
As an outside chance...
You could try clearing your cache in case it's a versioning issue.
Failing that, I suppose you could maybe install the Silverlight and blend sdk.
One thing you could easy try.
Does Silverlight work for you generally?
Follow the link on this page:
http://social.technet.microsoft.com/wiki/contents/articles/30387.silverlight-trouble-shooting-installs.aspx
If that errors then it's the install on your machine.
Hope that helps.

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,

Mac OS X Server Forward Proxy(Web Caching)...setup a website for the proxy???

My office is a Mac environment with a couple of windows pcs. To save on bandwidth i would like to setup a Mac OS X Snow leopard server with a web caching proxy, forward proxy. I read this link from apple
Server Admin 10.6 Help: Configuring Web Service Proxy Settings
i understand that to set this up i must enable it on my Mac Server and also on the clients(end user) web browser. What i don't understand is this part:
"When setting up a forward proxy, make sure you create and enable a website for the proxy. You might want to disable logging on the proxy site or configure the site to record its access log in a separate file from your other sites’ access logs. The site does not need to be on port 80 but setting up web clients is easier if its browsers use port 80 by default."
Create and enable a website for the proxy??? I don't understand, why do i need a website for web caching? Shouldn't the settings in the web browser direct the http requests to the mac server and it does the rest, what has a website got to do with it and what type of website?How?
Please help, thank you in advance

(WWC-40019) web cache connection error

Dear All,
I installed Oracle9iAS Release 2 Portal & Wireless installation type on my PC and the Oracle Infrastructure on another PC. When i tried to follow the described steps to shutdown my Oracle9iAS instance and then the Infrastructure instance to increace the RAM size of the Infrastructre machine and when i tried to startup the infrastructure and then my portal instance. I faced with the problem that my portal instance can't connect to the web cache and got the following error message :
Error: Could not open web cache connection. The portal use-web-cache setting is set to ON while web cache
may be down. (WWC-40019)
Any help will be appreciated.

This error could happen because of various causes. These are mentioned in the Config Guide.
Oracle9iAS Portal Configuration Guide Release 2 (9.0.2)
8.1 Oracle9iAS Web Cache related issues
Error: Could not open web cache connection. The portal use-web-cache setting is set to "on" while web cache may be down. (WWC-40019)
http://portalcenter.oracle.com/pls/ops/docs/FOLDER/COMMUNITY/CONFIGHTML/cgtroub.htm#1015385
Most often the reason is that of wrong Web Cache related config. info.in the Portal.
The following doc on scripts might help you address the config. issue
B.2 Oracle9iAS Web Cache configuration scripts
http://portalcenter.oracle.com/pls/ops/docs/FOLDER/COMMUNITY/CONFIGHTML/cgscript.htm#639250
If your problem is still not sovled you might want to read the following sections

Web Cache Not Found

I log into application server control to view my middle tier installation. From there I click on the check box for web cache and click the stop button. Stopping the web cache fails with the following message "An error occurred while stopping web cache. Target does not exist." I receive this same message if I attempt to start web cache and I don't understand what is prompting this message and why I'm unable to start/stop web cache.

Did you select to configure Web Cache at install time or did you select to do it later ?
Sounds like you have some steps left to configure Web Cache and EM
