Subject: Proxy User implementation



Hello All,

In our project, we need a proxy user functionality.  Below is the steps
I'm looking for to implement.

Portal Proxy
-  There will be a  "Grantor Pick List" portlet that will have a list of
Grantors user id for the Grantee's to choose.
-  All the Grantee users will fall under a role  "Proxy User"
-  The "Proxy User" role is entitled to access the "Grantor Pick List"
portlet.
-  Once the user selects a Grantor user Id from the pick list and click
submit, the action to render the portal page of the selected grantor's
id.

My question is more towards the last step.

1. If I tweak the authentication to check the grantee's user id to be
part of the proxy role and return a "true" value, and call the
JLoginUser action , will the above functionality can be achieved??. I'm
hoping ..yes. Appreciate your inputs on this.

Thank You

- Shan

In all the experiments I have seen (always on 1GB dual PentiumIII 
machines), Jetspeed degrades sharply at about 50 concurrent requests, and 
this has not changed in the last year. You could be seeing the same 
behaviour, but scaled to your CPU, RAM and architecture. I would try to 
use less concurrent requests (at a sustained rate) to test the limits. Try 
several hours with 20, then 50, etc. Also, notice that the server hotspot 
VM needs time to see hotspots and optimize them, and during method 
compilation it actually slows down the whole system.
Yes, somewhat exact behavior I'm seeing. Below is the hardware config of 
our machine.  We ramped up 1user every 10sec up to 100 users
and the 100 users stayed 30 mts executing bunch of portal actions.  I see 
spikes at 28th minute with just a Hello World portlet. I'm also
investigating JDK1.4.x and Borland 5.x to see any cause. will post you with 
more information. thanks a lot

Another useful information.  We set the heap size to 750meg.  The users 
load tested are 100 users with a think time of 30sec to 60secs
We see the major GC starts when the heap is full and clears  550meg of 
memory with live objects using 200meg. with in a span of another
5 secs , we see the remaining 550meg is again used and the major GC is 
triggered.  the response time suffers during the major GC running period.

Hope this helps

Feel free to criticize. It is the only way we have to improve Jetspeed.

We are seeing the Garbage collector (Major GC) getting triggered 
frequently as I think huge set of objects are getting created.
Some profiling could be handy. AFAIK:

Wrappers for security are not recycled (they *must* be inmutable)
PortletSets are created new for every request, due to threading issues.

are missing some "nullification" in permanent objects.

The registries are reloaded every 5 minutes, meaning a whole set of Castor 
marshalling and new objects going on (and fading) happens. If you don't 
have registries that change a lot, you could make this interval greater.

Every time DiskCacheDaemon runs, it will call xerces and xalan to 
transform RSSPortlets.

Every 30m you will have tomcat sessions expiring. If your testing does not 
keeps the sessions, you will be filling a lot of memory with fake sessions 
which will never be reused. I imagine you are using a testing framework 
that keeps sessions for a number of hits per "user".

A lot of other objects could come from either Velocity ASTs, Torque peers 
or other places. Even from your portlets ;-)

About Spring 2001 some profiling and tuning was done, by the IBM team, 
David, Raphael and myself. I don't know of other such effort since then. 
This led to rundata and some other objects pooling in turbine, and some 
changes of String concatenation to StringBuffer.append(). We also 
discovered a lot of duplicated initializations and similar stuff. It is 
always funny to see how big bugs can hide in code.

But the behaviour you are seeing looks more like the bug I pointed below 
or a bug in the hotspot compiler. Could you switch temporarily to jdk 
1.3.1_07 or 1.4.0_XX and see if the same happens? (According to reports in 
cocoon-dev, 1.4.0 does not have the StringBuffer bug)

This could be inherited from Turbine implementation.  We are now playing 
with the various options in the Garbage Collector
part of the JDK 1.4.1, which is running the GC parallel, setting high 
heap size,  giving some % for young generation Vs old generation etc.
Most likely to my knowledge the minor GC looks only the younger 
generation area as we didn't see any benefits in increase the
% of younger generation.  Apparently the spike still remains and gives 
poor response time just that the symptom happens way early
or later during the tests depending on the heap size and GC configuration.
If the problem is that some "bunches" of objects get into "old" space 
because they are pointed by persistent objects, then a juditious ammount 
of "= null" on recycling can help a lot. I've just checked 
DefaultJetspeedRunData and it is disposed properly (unless something is 
broken down in Turbine and it is not really disposed).

Jetspeed Performance tips

[Shan Gopalakrishnan]

Hello all,

Thanks for the great posting on Jetspeed mailing list.  We are evaluating 
Jetspeed for use in a project within Cisco.  I hope you can shed some light 
on some of the problems we are facing.

In a very simple test of one portlet that has fixed content (no business 
logic, no database access, etc.), we have observed some weired behavior and 
are suspecting Jetspeed is the cause.  We use LoadRunner to run 100 
concurrent users that pull the same page that has the one portlet of fixed 
content.  It runs smoothly for about 25 minutes (it takes about 16 minutes 
to ramp up the 100 users) and then the response time starts to climb quite 
sharply form < 1s to 8s and then to > 20s or higher while CPU goes from 75% 
to 45%.  We put the same logic in the plain JSP and ran it with the same 
load and response time was always flat under 1s. We put in the recommended 
Jetspeed settings.

Has any one done similar  tests, did you observe something like that?  Do 
you have any suggestions where to look further?  This is on Solaris 8 with 
JDK 1.4.1_01, Tomcat 4.1.18 and Jetspeed 1.4b3.

Thanks!

Observed spikes

[Shan Gopalakrishnan]

Hello all

we are doing a load test of our portal application which is using jetspeed. 
We see some sudden spikes after 30mts of running time with 100 simultaneous 
users in the load.  We did similar tests in the same infrastructure with 
standard jsp/servlets and this doesn't occur there.  It seem to occur only 
with jetspeed application.  Anything specific that I should refer to or 
focus on in terms of configuration or tuning ??
appreciate any information .  Thanks in advance.

PSML Manager

[Shan Gopalakrishnan]

Hello all

We see some performance issues during high load particularly in PSMLManager 
area.  We are thinking to remove the current implementation and  torque 
overhead and keep it simple with some standard JCS cache 
implementation.  Any inputs on where I should look for the PSML Manager 
implementation will help me.

thanks a lot in advance.

information needed on performance/load testing (HELP..!)

[Shan Gopalakrishnan]

Hello all

I'm running a load test in a portal application that is using jetspeed 
framewrok.  The load test tool used is Load Runner from
mercury interactive.  I also used OptimizeIt during the load test sometimes 
to identify some hot spot areas.
We are trying to run 50concurrent users in a powerful solaris box with 2 
CPU's, heap size set to 500MB and the sleep time between the concurrent 
user requests are 30seconds and the users stay in the system doing 
activities for 10mts during the load.

I had two questions based on the symptoms I saw during the load test.

1)  In JetspeedResources.properties.

#The following property is used for DatabasePsmlManagerService? 
only. The default is false that is caching is
#not allowed with DatabasePsmlManagerService?, as the current 
implementation of caching does not work on a
#distributed environment. It works only in a single server 
environment.
services.PsmlManager?.caching-on=true
services.PsmlManager.cacheSize=50

When I turn on the above property, the performance increased drastically 
and the memory increased as well. But at some point when I hit the 20 users 
concurrent, it breaks the entire unix process that is running the 
application server and the whole application dies.  Not sure this is a bug 
and anyone encountered this.  If the value is set to false , then the test 
goes through fine, but the round trip performance is very slow.
Appreciate if there are any information on what is the implementation 
behind this.

2) what is the value to be set in the below properties for the above load 
test scenario.

In JetspeedResources?.properties
Everything under the ThreadPool? Service heading -- Setting these 
up to the default seemed to adversely affect performance.
services.ThreadPool?.init.count=5
services.ThreadPool?.max.count=20
services.ThreadPool?.minspare.count=5

Appreciate any information on the above questions and thanks a lot in advance.

StaticServlet's static method.

Hello all,

This is a velocity template question.

I want to expose a StaticServlet object that I have in the velocity context 
and refer in the velocity templates.
Also call its static method by passing the request object to it.

The equivalent in JSP is

<%= StaticServlet.getStaticPath(request, "/images/globe.gif")

I'm still trying to understand velocity better.  Any help greatly 
appreciated .thanks

Re: JSP vs Velocity

But wondering the overall templates need to be still velocity in jetspeed 
framework.
the portlets can be jsp.  remember that context object is always null in 
jsp :-)

I would say that it works perfectly well for my strategy, but I believe
there's still an issue over how JSPs handle actions.  I've been pushing that
one off, but I will eventually reach a point where I can't ignore it.

FWIW, my strategy is to prototype in JSP, then move the code into a class
that inherits from AbstractInstancePortlet.  For the most part, my approach
has been to have that class generate what amounts to a List of objects
which are placed into the request.  The JSP is then limited to iterating
through the list and simply displaying the getXXX attributes of each object.
My JSP files are nothing more than iterators, and this works pretty well for
me.  If this is a radically incorrect approach, I'd appreciate the feedback
now!!!

Once you reach this level of isolation, it really doesn't matter if you
choose JSP or Velocity.  My rational behind choosing JSPs is as follows:
1) Its faster (for me, but YMMV) to prototype my Java code in JSPs
2) Dreamweaver understands JSPs
3) If I need to contract out, JSP-savvy designers are far more common (and
hence cheaper) than Velocity-savvy ones
4) Thus far, I have the CPU cycles to spare on JSP, though this may change
once I go live

Re: JSP vs Velocity

[Shan Gopalakrishnan]

I have one point to share.
I had a prototype created using 1.4a and trying to port to 1.4b3, but went 
through slightly tough time
in porting the code to 1.4b3 as I had done some good amount of 
customization changes to jetspeed 1.4a templates.

The velocity templates has a lot of macros coded in it and any changes to 
the templates for customization
heavily affects the upgrade to new version.  wondering what is the general 
opinion on this.

Another one , wondering how the content management tools will deal with 
Velocity templates now as it looks
not a clean tag oriented template.

Lastly we observed the velocity templates are consuming more time in some 
areas while rending the page.

The best way to do it is to just do it, dive in, make it work.  As you do 
it write documentation.  Submit it as patches.  You'll find others will 
correct them and expand upon them.  In the end, the documentation is 
improved and the project improves.  Your understanding improves and your 
time investment is limited due to the contribution of others.

Or at least that usually works for me.  (BTW, thats kinda part of how I

Before I try further, thought I could give it a try here.

if ((p != null) && (stack.size() > 1))

(String)p.getTitle());
else
  customizationState.setAttribute ("customize-paneName", "*");

can anyone let me know which property this code is looking for ? and in 
which config file??

Thanks a bunch

Re: PSML Importer Service does not work

Looks like there is a bug in 1.4b3 on this.  Several people are hitting 
this problem. I heard it works fine in 1.4b2 and i'm
yet to check this. But make sure you do the required changes in the 
Torque.properties.  Refer to jetspeed documentation
for changes.

Hi,

Here is my environment: Windows 2000,Tomcat 4.1.12, JDK 1.4.1, 
Jetspeed1.4b3, mySQL

The importer service does not populate the data into database. I already 
created the jetspeed structure in mySQL.

Someone can help me to resolve this issue?

Thanks,

Zak

I ramp up the users by 25 users.  Started with 25 and increased 25

Hi

I'm using Tomcat 4.0.3 and Jetspeed lastest nightly build.

Although I deploy my actions in the WEB-INF/classes and have the module 
package specified in the Turbine.properties,
it fails to load the action classes throwing ClassNotFoundException. below

looks fine. do I miss anything.

Re: xsl portlet.

[Shan Gopalakrishnan]

Anand

Good points.  I still didnt probably give you the right requirement.

I have a ejb in the app. server  which returns a xml string .  This ejb is 
called by rmi/iiop from the Portlet class.  Now I'm looking
at using this xml string as an input to the xsl.  If you see the portlet 
definition, it takes a vm uri.  I'm not sure why should I use
a vm ?  Appreciate any of your inputs on this.  Thanks

Re: portlet actions min/max/close/edit.

Todd

In your answer I can see only the portlet action mapping to a java class . 
But what I'm looking for is where is the api for eg.
what to call for Edit,  what to call for Minimize etc is defined? .  How 
does it know which api to call from the class for different
events?

Re: Réf. : manipulating skin look & feel.

[Shan Gopalakrishnan]

Pierre,

Is there a possibility to manage seperate skins from the customize window ( 
the little pencil icon next to the tab's..)
Right now it has drop downs which has themes which affects all the portlets 
in the tab.   Is it possible to customize
the themes for the selected portlets in the tab?

David, this is a awesome explanation. Thanks a lot.
  But that made me curious to ask little more question.

On the below description

 >>  $screen_placeholder
 >>The screen placeholder calls the specified screen in the request, or the

where is the definition of  $screen_placeholder.?  If it is request to send a
custom screen thru' the request, how do we do that?. any inputs on this
will help me.  I will also go thru' turbine docs.

output html

[Shan Gopalakrishnan]

Hello team

Are there any templates assoicated to the overall PSML?.  How we control 
the html that is getting generated
for the overall PSML which includes all the portlets.  I understand there 
is a possibility to assign a template
for each portlet . but I'm looking to control the html page that is getting 
generated for the entire psml after
the portlets assembly?.

Re: changing login page.

[Shan Gopalakrishnan]

Anand , thanks a lot.  Actually I'm going by the default.vm with velocity 
as by base template. I want to avoid
the top, left, bottom and  just use a login page in this.  right now the 
templates are set using  $jnavigation.setTemplate() method.
which calling top.vm , instead i want to change it to the login.vm in the 
screens folder which should then forward the action
to the portal page . appreciate if you throw me some light here.  thanks a 
bunch.
