List of actual HTTP Sessions
Hi,
does anybody know, where I can find a list with the actual running
HTTP Sessions?
Additionally, can I specify it somewhere, that a log is written,
when a HTTP Sesstion is timed out?
Thanx,
Bernhard
Hi,
Use javax.servlet.http.HttpSessionBindingListener
Which causes an object (in your case the logger) to be notified when it is
bound or unbound..
you could also use HttpSessionBindingEvent
Which is a solid object extending the above..

How to find the list of users loggin through HTTP session
Hi All,
we are using SRM 5.5 system with ITS. I am able to find the list of concurrent users from ABAP level using report "CCUEVAL" but how do I know the list of concurrent users logged in from HTTP session?.
could you please let us know the SAP note number or any report?
Thanks in advance,
Mohan KarriHi Uday,
thank you very much for your prompt response.
I need a report because by end of every month I would need the average peak http users list for the reporting month.
or tell me how to find " how many users logged in through HTTP session in a day?"
Thanks

In-memory replication of http session is not working in BEA7 cluster
Hi everyone,
I have 3 managed servers in Bea7.0 SP4 in a cluster. The client requests are sent
through apache web server. I have given cluster address as URL in httpd.conf of
apache server which sends the client requests for dynamic pages such as JSPs and
servlets to the weblogic cluster.
Load balancing is working fine. I ensured this from the log files of all the 3
servers. All the 3 servers are getting different client requests and thus load
balancing is working.
Now, I wanted to achieve Fail-over. I do not think that i should use proxy plug-in
for this. I feel the cluster itself will handle fail-over provided i make the
http session as memory replicated.
I updated the weblogic.xml with the following entry :
<session-descriptor>
<param-name>PersistentStoreType</param-name>
<param-value>replicated</param-value>
</session-param>
</session-descriptor>
I guess this is sufficient to make the http session as cluster aware.
But when I shutdown server1, the user connected to server1 will be kicked out
of the session and come to login page through server2 or server3 which are running
fine.
Could anyone help me to achieve http session as cluster aware. Does it indicate
that I have to go for WLS proxy – HttpClusterServlet to achieve fail over for
http session ?
BTW, for your info, i am using setAttribute() and getAttribute() while manipulating
the session.
thanks in advance.
Hi Ryan,
Thanks for ur valuable input.
I can see failover working.
But, I can not continue with the same session in my application.
I printed session Ids before and after failover, I found both are different.
I guess session replication is a responsibility of weblogic/apache plugin.
If not please let me know which all settings I should do to make failover working?
Thanks again.

Model session not in sync with Http Session
Hi All,
I have an application developed in JDev 11.1.1.4 and we are not using ADF Security for login.
The problem occurring is randomly some of the LOV on my home page are getting null (having no data). These LOVs are populated using the values passed as bind parameter from the login values (basically HTTP session values at web layer). So i added a method in all the task flow to set the session value at the model layer (default method) . Also on each call to the Am Impl call i am setting the value in the HTTP session and then invoking the method, but some how what happens is the Model level session value is not in sync with HTTP session and the list gets empty.
Any inputs what i can do to get out of this prblm ?
thnkIn this case you need to overwrite the activateState/passivateState method of your am and store/reads the values from the xml structure you get as parameters to this methods.
For more detailed information check the docs http://download.oracle.com/docs/cd/E12839_01/web.1111/b31974/bcstatemgmt.htm#sm0495
By the way, this is nothing you need to open an SR on as it's working as designed.

How can I flag HTTP session attributes to not be replicated ?
WLS 5.1 SP8 - In memory replication of a stateful servlet. Is
there any way to flag data that has been, or is being, loaded into
a HTTP session so as to not be replicated ? It's a long story,
but we have some data loaded into a hashtable, more specifically
a Properties object, stored in our session. With the hastable
already loaded into the HTTP session, weblogic does not detect
when we add values to the table, and therefore does not replicate
the changes. Which is ok since WLS is working as designed. To
get around this we load the hashtable back into the session everytime
we add a value to the hashtable. Yup, I know that's ugly. Anyway,
what I'm trying to find out if is there is an attribute that we
can set to indicate, to not replicate this data or that data.
Something along the lines of a attribute on a per hastable value
basis. For example, I load value A into my hashtable, then I
need to put my hashtable into the session to get it replicated.
Next I load value B into the hastable, and again to get it replicated
I have to load the entire hashtable back into the session. The
problem here is that the entire table gets replciated. Does anyone
know if I can set an attribute on value A, when I'm adding value
B, so as to not replicate value A when I reload the table ? Of
course all goal is to not store so much data in the session, but
I'm trying to find a work around until that is completed.
Thanks,
David
Where can I find documentation on the details of how Weblogic decides what will
be replicated in the HTTPSession object (for example, it only replicates attributes
which are set or updated using "setAttribute()"?

How to do http session stickiness based on URL patterns?
Is there a feature within the WL plugin for Apache that would allow me to emulate the "jvmroute" session stickiness behaviour as provided by Tomcat and its plugin. I would like to have the control to tie requests from http clients to particular WLS servers in a cluster depending on the URL. For example http://foo.com/web01 requests would be forwarded to an appsererver app01 and so on. For all other requests (e.g http://foo.com/web), the WL plugin would do its normal load balancing ignoring the stickiness. From my understanding the WLS inbuilt http session stickiness is based on JSessionIDs which are exchanged using cookies - which is something i cannot use in my case since i want the stickiness based on URL patterns.
I am using WLS 10.0 with Apache 2.2.4 on Linux.
Thanks
RamdasSession is not replicated across all the servers in the Cluster.
Apache knows which server to go using the JSession ID.
There is a concept of primary and secondary, secondary is selected based on the replication groups there are configured in the cluster.
you can configure the cluster so that /web01 requests go to different cluster, and /web requests go to different cluster.
but you can get all the funtiionalities from the single cluster.
Do you have any java caching that you are not able to replicate across the cluster ?(I know this can be done too).
let me know what you are actually trying to solve by doing the behavior you explained. -
HTTP Session caching possible using WL7 JAX-RPC ?
We're using WL7, and using the JAX-RPC API to access external webservices.
Basically, we create the appropriate 'stubs' from the target WSDL using
clientgen. Then we invoke the target method. Code looks something like this:
Client_Impl client = new Client_Impl; // implementation of target
ClientPort_Stub stub = client.getClientPort();
stub._setProperty(javax.xml.rpc.Stub.ENDPOINT_ADDRESS_PROPERTY, url)
stub.invoke(args);
Now, when is the actual endpoint URL being created ? Is it when the invoke()
method is called ?
It cannot be during the constructor since I pass the target URL after that ...
My problem is that I have to call the 'invoke' method quite frequently, and hence
would like the HTTP session to be reused, rather than recreated each time. Right
now,
I construct the stub each time I have to call the target method, and I'm wondering
if
I just cache the stub and keep calling the target method each time, will the underlying
HTTP session be reused ? Any ideas ?
Currently, if I do netstat on my Sun Solaris box (where this runs), I see the
TCP
connection being recreated during each invocation ...
-johnHi John,
You can do multiple invokes on the same stub. There is no
need to create a new one for each invoke.
WLS 7.0 use HTTP 1.0 with keep alive. If the server respects
HTTP keep alive, then WLS will not create a new connection.
HTHs,

Hello
I'm looking for a way to close open HTTP Sessions on the J2EE. I know how to close the session in the WebApplication and I know how to modify the session timeout but that's not what I'm looking for. I need to be able a selected session on the J2EE.
Through telnet I'm able to list the sessions with HTTP_SESSIONS full. Is there a way to close sessions this way?
Thank you for your help.Hi Christian,
There is no tool or command to close the http sessions on the j2ee engine. If this was allowed you could end up deleting perfectly good user sessions. In case you see a build-up in http sessions i would say this needs to be investigated.

At Workload Analysis (sol man diagnostics) what is the difference between the KPIu2019s u201Cavg http sessions / hu201D and u201CPeak http sessions / hu201D?
Because I did a simple test at Sol Man Diagnostics, I selected a range of 1 hour at the same day, and I have difference values for those KPIu2019s and I suppose they should be the same as I have a range of just 1 hour.
The same doubt I have for u201CAvg logins /h u201C and u201CPeak logins /hu201D, because I have different values too.
Regards,
Walde RequenaHi,
When you choose from the dropdown list BSP application
and you fill in as name 'system', you have access to
standard solutions for login, buffered pages, automatic logoff,...
the two pages i mentioned handle the sessions for your application.
I used the buffer-page for my application, which has only
one session when i view it in cic0.
I only inserted my index.htm into the header in de copied source.

Need someone to clarify about weblogic connection vs actual db session
Hi,
I'm working on CRM Application which working on Weblogic application server. But I have some confusion between number of connection in monitoring tab( picture from this link [http://postimg.org/image/nbmjncq2n/]) and actual number session that I capture from DBA.
from the picture, the highest number of connection in weblogic is just 5 but when DBA capture active connection to me, it show like 400 active connections. Anyone can explain the relationship between this 2 values. Is it related or not?
Thank you

Share http session across multiple EARs
I am curious to know the following:-
--> is it possible to share http session across multiple EARs running on same Weblogic application server.
i.e weblogic server/Jboss
--> is it possible to share http session across multiple EARs running on different Weblogic application server.
i.e weblogic server/Jboss
Please share the steps/way to acheive the same.What are you trying to achieve / accomplish by splitting it up?
e.g. Clean Build in workshop will be faster for multiple EAR's , but unless you have all your application level libraries as shared libraries you might increase your runtime footprint. or you might want independent deploy/redeploy for your apps etc.
If however you need the session to be shared , that these aren't really independent web-applications and shouldn't be separate ear's. In most cases though you dont actually need the session as shared (e.g. a user's data is fetched from the database , you dont really need the session shared, you need a single shared sign on). So when you say is the session shared, what is the data that you need shared? should it be in the session in the first place?
And finally are these webapp's really independent (functionally ) or not?

Hi,
I repost this message in hope someone could help me in SEEING it :
i am looking for some code (if any exists) to do metrics on what is really hold in the http session :
how can i get info on :
1. nb of user sessions actually in memory
2. for a given session, what is the size of all objects in the session
This can help in sizing server memory.
Perhaps there is some servletinfo utility somewhere that i can reuse.
Thanks
HYAI don't know what kind of container you are running your application in, but some have tools for analyzing the performance and memory management of the container. For example Oracle's Enterprise Manager for Oracle's containers for Java (OC4J), lets you see these things. I'm not sure if other servers like Tomcat provide the same thing, but you might want to look into that. Hope that helps.

How to close a HTTP session when a user closes the window
Hi,
I am having problems when closing the browser of a BW web report. After I closed the browser by going File->close, I ran SM04 and found out the Plugin HTTP session hangs at the server side.
How can we terminate the Plugin HTTP session at the server side when user closes the internet browser?
I did implement a logoff function at my web template and this was implimented on the Menu page, if user clicks on the logoff, the Plugin HTTP session is terminated at server side correctly.
If user navigates to the other pages from the main page... then the logoff function was not implimented in the other pages. So many of the users are closing the windows directly. Eevn if we impliment logoff in all the subpages, As you know, 50% of time user will close the report by closing the internet browser instead of clicking the logoff. That leaves lots of hanging Plugin HTTP sessions at our server side.
Regards,
TonyHi,
And also take a look on the Genral property of the web template. We solved this problem by changing only this property (no extra things).

Thanks for help!
JAHi
If you want to avoid a blank page with logoff button, add opener=0
<a href="<SAP_BW_URL CMD='LOG_OFF' ~command='logoff'
>" onClick="javascript:window.close(opener=0);">Log off</a>
If you want to close the session via X, use this code:
create a sapscript function
function closeSession()
logoff()
window.unload=CloseSession()
However, the Plugin HTTP session isn't killed.
