WebCache Performance

I have strange problem in 10g(10.1.2.3 - running on Linux VMWare) were every login generates 13 Soft Invalidation request and whenever i have 20-30 logins/min WebCache Spikes High on CPU (may it has to process Invalidations first instead of processing the incoming request) and the only option i have is to clear Webcache (Hard Invalidation). I have 9 portlet on HomePage rendering from 4 different WSRP Providers (Each Provider has 2 JVMs).
So my question is does anybody had gone through such situation or is there anyway to avoid Invalidations. Right now the page is cache @ user level. I appreciate if anybody share there experience.
THanks

hi,
I would like to ask you about your netwrok is it ok?.
If U've slower network then U can tuning Webcache to deal with slow network.
In ORACLE_HOME/webcache/internal.xml just add the following line;
<CALYPSONETINFO OSSEND_TIMEOUT= " 300">
This parameter will increase timeout tolerance for Webcache.

WEBCACHE POOR PERFORMANCE in Servidor HP-UX

Access through webcache is extremly slow. The same is not happening when the
access is done directly through http port without webcache, the response is in
within seconds. The same issue is described as bug 5125091. Has this bug been
resolved?

Mod_osso partner application and webcache site to server mapping

hi, need advice on the following.
i have an app server container (only OC4J and no portal,forms etc) hostname abc.test.net installed with the option to registered to the sso server (http://mylogin.test.net), which is on a physically seperate machine.
i have a java application deployed on a 10g app server container. the log in portion is handle by the login server using the mod_osso.conf file.
thus when i type http://abc.test.net:7777/myapps, i will be prompted to login via the sso server.
this is working fine.
then i put a webcache to front this app server, so that users will use a sitename (http://myapps.abc.com) defined in the webcache (mapped to the app server) to access that application.
so now when users type http://myapps.abc.com, they are still prompted the sso login screen. but after logging in, they are shown a red coloured bold text error message "ORASSO Failure-Unable to Process Request" page. this error page has the url of app server http://abc.test.net:7777/osso_login_successxxxx.
if i manually replace the 'acb.test.net' to 'myapps.abc.com', my application will be displayed correctly, and i am logged in.
how can i resolve this problem?
question:
1. do i need to re-register http://myapps.abc.com as a partner application?
2. if so, do i perform the registration from the webcache, the app server or the login server itself?
pls advice.
thx.

Access 2 clustered instances on oracle 10g AS's - Webcache as loadbalancer

Hi,
Sorry i dont have a solution to your problem.
But I have a query for you, kindly help me out.
1. I have 2 oracle application servers(10g)-without webcache installed on 2 different linux machines.
2. I have a default OC4J-instance 'home' on both machines.
3. Now I deploy a war application on both machines with same name 'CS_APP' and context as 'CS' on both the application servers.
4. I am able to successfully access the application from individual servers as follows:
http://bslchnlas01:7777/CS/Index.do
and
http://bslchnlas02:7777/CS/Index.do
5. I also have performed the steps to make these 2 applications cluster aware.
6. My problem is I am not able to connect to these 2 applications in a cluster by using a urlfor example
http://bslchntest:80/CS/Index.do from a webcache installed on a third machine(windows). Also let me know how will the failover mechanism occur in this application.
7. I have made the required changes for failover mechanism in the mod_oc4j.conf file in both the servers.
A solution to my problems would be appreciatable.
Thanks,
Siddhartha ([email protected])

Siddhartha:
There are two tasks to complete for your question.
Task 1: Configure Site Definition (bslchntest:80) and Site to Server Mapping to load balance traffic to the two origin servers http://bslchnlas01:7777/CS/Index.do and http://bslchnlas02:7777/CS/Index.do.
Task 2: Configure the two Origin Servers to properly comminicate with the Web Cache installed on the third machine. For instructions read Section 3: "Dedicated Topology Option" of This Paper.
Web Cache will load balance incoming traffic to the two origin servers you specified. If one fails, all traffic will go to the remaing origin server.

I have performed following steps to overcome the problem :
This is what i have done on the first attempt :
1) replaced port 80 by 7777 in webcache.xml
2) added 'Listen 7777' in httpd.conf
3) restarted opmn
Following steps done on the second attempt :
1) replaced port 80 by 7779 in webcache.xml
2) added 'Listen 7779' in httpd.conf
3) restarted opmn
My webcache and webcacheadmin shows down in the opmnctl status.
Both above attempts were unsuccesful, Please support with a solution to above issue. We are on Windows 2003 R2, OAS 10g r2 (10.1.2.0.2). My webcache has been down for past 3 days and one thing i have noticed is that it is not writing any logs to $ORACLE_HOME\webcache\access_log. Access_log file was way too long when i checked 2 days ago so i moved the access log to a different location and re-created access_log by editing webcache.xml, i dont understand whether existing problem is due to port conflict or it is an issue with webcache unable to write to access_log. The current size of access_log is zero.
Look forward to your urgent support.
Thanks
Mir

Portal performance monitoring scripts : (Unable to generate reports) HELP

Hi,
Using 10.1.2.0.0
I followed README.html document to load the logs files to generate reports for Portal Performance.
First of all while running loadlogs.pl I keep getting the following error. I even tried adding -nodirect but still gets the same error. Don't know why. But it looks like there is some data loaded in OWA_LOGGER table

I tried running some other scripts also but somehow I don't see any reports being generated as opposed to what is said in the README.HTML document i.e. "A sample web page (reports.html) is included which provides links to the generated reports.". How really I get to see the reports, where are the reports generated, is it something else that I am missing. No matter what script I run I don't see any report being generated. The document is not so clear. Can someone please help me out here. Thanks

Hi!
You have to change to directory
ORACLE_HOME$/portal/admin/plsql/perf/scripts
(you can find reports.sql in it) before you run reports.sql script!
It will produce several .txt files.
After running the script just open reports.html, that will point the generated files.

FRM-92101: Load Balancing Forms 10g with Webcache

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 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:
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.

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.

This means that every 2 min is trying to refresh the agent?There is any way to change this interval?

We are having some performance issues in the past few days and for me it looks like sometimes zmd is using a lot of memory and CPU.
Maybe changing the refreshing interval could solve the issue?
Many thanks

Franc,
this looks like a problem we have reported I think at the beginning of the last year and it took a long, very long time till we got a fixe for it. I should have been fixed in HP4 but we still see the issue.
Wen you check the zmd-message of a server that does not apply the policy or install the bundle at the refresh interval you might see the following:
Code:
30 May 2008 08:39:28 INFO WebCache Attempting to retrieve 'https://zlmsrv/zenworks-pkgmgt/repo/getBundleInfo/sles-10-x86_64' (try 1)
30 May 2008 08:39:28 INFO WebCache Forcing cached data for https://zlmsrv/zenworks-pkgmgt/repo/getBundleInfo/sles-10-x86_64
That "Forcing cached data" means it has not contacted the zlm server for the bundle information and used just a local cached one which is an old version and does not know anything about the new bundle.
When you runa manual refresh it works, or when you send the device a refresh from the zcc it works also.
Just the install on refresh does not work.
And does not work on all systems, a few always install it.
I have just yesterday submitted new log files for this problem. I have to wait what they say about.

Docs. for Monitoring Installing Portal Performance steps/scripts etc.......

Hello can someone please point me to the documentation on how to setup the Portal (10.1.2) for generating and loading performance reports. What files do I need to modify and what scripts to run. I want to generate reports to check the performance of the Portal pages, apps. and overall performance.
Thanks

I ran the following command the data got loaded but I am not sure if all the data is in the tables due to the following error. Can someone please tell me what's causing the following error occurs when running loadlogs.pl:

Webcached.exe uses all CPU on IAS server

Hi, I'm having trouble with a process called webcached.exe according to Windows task manager, this process takes all available CPU resources, so our IAS server hangs. Anyone why this is? Any help highly appriciated! I'm pretty new to Oracle Application server, and have not experienced this before...
Is there a way to "go around" web cache until this issue is resolved, i.e. not use cache for a while perhaps? Longer responses are better than complete hangups....
I've tried to just stop the webcache process, but this apparently is not the way to go...
Windows server 2003 + IAS 10g (9.0.4.1.1)

Your post is a while ago... but you should upgrade Web Cache to 10.1.2.3, or install it in a separate location and configure it against your backend application. This is supported.
Webcache 9.0.4 is known to have some performance issues :)

ADF based HTML page is a performance dampner. Any Solution?

Hi,
I am using JDev 11.1.1.2.0 with ADF 11g.
We have built many pages based on ADF faces. Each screen has its own set of number of fields based on what is to be depicted to the user.
We have used inbuilt ADF css.
Now when I see the view source of the page it turns out to be in MBs even for simple small screen. What is it that I can do which will help me reduce the size of my page?
It is real pain to see the time taken to load the page.
Thanks in advance.

For a smaller javascript download you need a page with minimum amount of components. Then you need to setup javascript partitioning as explained here:
http://download.oracle.com/docs/cd/E17904_01/web.1111/b31973/ap_config.htm#BABCJIDJ
This will reduce the load time for the initial page.
Note that as Frank mentioned once the JS is downloaded it should be cached on the client.
You can also use WebCache to improve performance as explained here:

We don't recommend using CSS for layout control in ADF Faces.

WebCache ESI Environment Bug

I found a really stupid and frustrating but with the WebCache ESI Environment functionality.
I have an ESI environment file containing key/value pairs (in a flat XML structure).
I have another page which looks up values in this file, using the <esi:environment> and <esi:vars> tag to do the lookup.
The bug concerns whitespace in the ESI environment file. Specifically, if you have the following at the top of the file:
<?xml version="1.0" ?>
...it will not work. However, it does work if you have:
<?xml version="1.0"?>
i.e. no space before the last '?' character.
XML parsing should be able to cope with this kind of extra whitespace. This is a serious and frustrating bug.

The XML parser currently used in Web Cache is not a general-purpose XML parser for better performance. It may be switched to a general-purpose one for limitations like this in the near future.

Low performance when connected users exceed 250 in OAS10g

hi,
in OAS10g app server whenconnected user to app server are less than approximately 250-280 every thin is good and there is no performance problem,
but where connected users exceed 280 , server response to requests such as opening a form(without query data from db ) took 10-12 seconds.
in this case Os resources are: cpu usage <45% and mem usage <50%.
is it HTTPServer performance issue?
how can i solve this problem?
thank in advance
carol.

You can try to change the JVM for Forms Servlet, maybe add more Threats with more memory assigment and that this threats get distroyed after resolving certain number of request, also in Apache, you may want to increase the number of MaxClients Directive, as well the Max Connections in WebCache.
Greetings.

Quote Report - Performance

I have created a quote report with narratives around the opportunity, opportunity-product, and account information. The report contains a pivot table.
I'm getting very hit or miss performance results on the report. Sometimes the report runs faster for all opportunities compared to when its prompted with an opty id from a web link.
Any thoughts? There doesn't seem to be one column that makes a difference.
Also this is not an analytical report as the quotes need to be generated same day.

Hi Shaik,
Please remove all the join select queries and use 'for all entries' varaiant of the select query. Check whether you can create and use indexes in ur queries.
Thanks and Regards,

IS NOT NULL and performance

I have a performance issue with a query - it would be something like -
select col1,col2, sum(col3), get_val(col_4)
from table1
where
get_val(col_4) is not null
group by col1,col2, get_val(col_4)
I have simplified this but it is something similar. This works great - performance is great. Now I commented out the where clause as I needed to populate null values - and that's it the query does not retrieve the resultset - it keeps running forever. With the where clause it comes back in 60 seconds. There is only one row out of 560 rows that has null value for col_4 which i need to display.
Any help is appreciated.

The only difference I notice between the two sqls is HASH(UNIQUE) -
with IS NOT NULL in where clause -
SELECT STATEMENT     ALL_ROWS     1598     1     209
HASH(UNIQUE)          1598     1     209
HASH(GROUP BY)          1598     1     209
When is not null is removed from the where clause -
SELECT STATEMENT     ALL_ROWS     1598     1     206
HASH(GROUP BY)          1598     1     206
I'm guessing that the index is being used in the first scenario and not in the second. Any idea/suggestion as to how to over come this?
Thanks
