Session not being clean up by JRun

My application is using IPlanet WebServer and JRun3.02 Application server. I am having a problem with active session not getting cleaned up by the App Server. When the user goes through the application and finishes the process, I invalidate the session by doing 'session.Invalidate()'. I also have set a 30 minute timeout value in the JRun global.properties file to invalidate the session if the user starts but not finish going through the application. However, the number of active session count in the JRun log doesn't seem to go down. After a few days, I ran out of sessions and the application hungs. I keep a few objects on the session including a pretty big 'pdfObject' that I use to create a PDF document on the fly.
Any idea why JRun not able to clean up the sessions after the 30 minute timeout has passed? Does the fact that I have stored objects on the session preventing JRun from invalidating and cleaning up the session?
Thanks in advance.

Hi afikru
According to the Servlet specification session.invalidate() method should unbind any objects associated with it. However I'm not conversant with JRun application server so I can only provide some pointers here to help you out.
Firstly, try locating some documentation specific to your application server which may throw some light on why this may be happening.
Secondly, I'd suggest running the Server within a Profiling tool so that you can see what objects are being created and how many of those. Try explicitly running the Garbage Collector and see if the sessions come down.
Keep me posted on your progress.
Good Luck!

Portal session not being terminated. browser "unload" event

This line of code is in the portallauncher.default and eventually causes the problem:
EPCM.subscribeEvent("urn:com.sapportals.portal:browser", "unload", releaseProducerSessions);
releaseProducerSessions eventually calls a portal component
WSRPSessionRelease.. which is causing the problem.
When we upgraded from EP 6.0 to NW 2004, users started recieving the Netweaver Login Screen when they logged out and logged back in, in the same browser. We think this error occurs because NW 2004 implements Web Services Remote Portal functionality.
We are using SiteMinder as a third party session management tool.
What we found was that the Siteminder session was being killed but the Portal session was not. Therefore, when users logged back in they would see the generic Netweaver Login Screen, and they could actually just hit "enter" and continue to the portal.
A successful logoff, users clicked the logoff button, the DSM terminator was being called, thus killing the portal session, then a form was submitted redirecting the users the the siteminder loggoff page, which logs the users off siteminder.
When the logoff failed, we found that after the DSM Terminator was called
and before the page was being redirected, a portal component
(WSRPSessionRelease) was being called, which in turn, RECREATED the portal session. So the user never actually gets logged off from the portal.
We found that the WSRPSessionRelease component is set to
a "browser" "unload" event when the portallauncher.default component is first loaded. This is the same component that is being called when the user clicks the "X" to force close the browser.
Not everytime is the WSRPSessionRelase component being called before the redirect to the siteminder logg off page. Sometimes this component is called after the redirect, and we find that this is a successful loggoff.
The component is:
irj/servlet/prt/portal/prtroot/com.sap.portal.wsrp.coreconsumer.WSRPSessionRelease

Hello Michael,
The 'log off' issue is a known issue with Portal since EP 6
Had faced similar issue and SAP suggests to redirect the 'log off' link to another non-SAP site...like your company intranet site.
This will help the session to break.
There are 1-2 SAP Notes on this as well.
Hope this helps.

Ritu

Obsolete jdb not being cleaned up

Hi,
Setup:
* We are using Oracle NoSQL 1.2.123.
* We have 3 replication groups with 3 replication nodes each.
Problem:
* 2 of the slaves (in 2 different replication groups) occupy much more space in JDB files (10 times more) then all the others. As these are slaves, and writes always go through the master, and all nodes in a replication group have the same data (eventually), I assume that this is stale data that has not been cleaned up by the BDB garbage collection (cleaner threads). Unfortunately the logs do not show anything new (since Dec. last year) and the oldest JDB files are from February.
Questions:
* Any ideas what could have gone wrong?
* What can I do to trigger the cleaners to cleanup the old data? Is that safe to do in production environment and without downtime?
* Is it really safe to assume that the current data in within a replication groups is really the same?
Thank you in advance
Dimo
PS. A thread dump shows 2 cleaner threads that do nothing.

1) The simplest and fastest way to correct the replica node is to restore it from the master node. We will send you instructions for doing this later today.Here are directions for refreshing the data storage files (.jdb files) on a target node. NoSQL DB will automatically refresh the storage files from another node, after we manually stop the target node, delete its storage files, and finally restart it, as described below. Thanks to Linda Lee for these directions.
First, be sure to make a backup.
Suppose you want to remove the storage files from rg1-rn3 and make it refresh its files from rg1-rn1. First check where the storage files for the target replication node are located using the show topology command to the Admin CLI. Start the AdminCLI this way:
    java -jar KVHOME/lib/kvstore.jar runadmin -host <host> -port <port>Find the directory containing the target Replication Node's files.
    kv-> show topology -verbose
    store=mystore numPartitions=100 sequence=108
      dc=[dc1] name=MyDC repFactor=3
      sn=[sn1] dc=dc1 localhost:13100 capacity=1 RUNNING
        [rg1-rn1] RUNNING c:/linda/work/smoke/KVRT1/dirB
                     single-op avg latency=0.0 ms   multi-op avg latency=0.67391676 ms
      sn=[sn2] dc=dc1 localhost:13200 capacity=1 RUNNING
        [rg1-rn2] RUNNING c:/linda/work/smoke/KVRT2/dirA
                  No performance info available
      sn=[sn3] dc=dc1 localhost:13300 capacity=1 RUNNING
        [rg1-rn3] RUNNING c:/linda/work/smoke/KVRT3/dirA
                     single-op avg latency=0.0 ms   multi-op avg latency=0.53694165 ms
      shard=[rg1] num partitions=100
        [rg1-rn1] sn=sn1 haPort=localhost:13111
        [rg1-rn2] sn=sn2 haPort=localhost:13210
        [rg1-rn3] sn=sn3 haPort=localhost:13310
        partitions=1-100In this example, rg1-rn3's storage is located in
    c:/linda/work/smoke/KVRT3/dirAStop the target service using the stop-service command
    kv-> plan stop-service -service rg1-rn3 -waitIn another command shell, remove the files for the target Replication Node
    rm c:/linda/work/smoke/KVRT3/dirA/rg1-rn3/env/*.jdbIn the Admin CLI, restart the service
     plan start-service -service rg1-rn3 -waitThe service will restart, and will populate its missing files from one of the other two nodes in the shard. You can use the "verify" or the "show topology" command to check on he status of the store.

Aq$_tab_p, aq$_tab_d filling and not being cleaned up

Hi all.
I have a simple 1 way streams replication setup (two node) based on examples. Replication seems to be working.
However, the AQ$_TAB_P and AQ$_TAB_D (on the capture side only) tables continue to fill (as well as number of messages in the queue and spilled lcrs in v$buffered_queues). Nothing should be spilling since the only things I'm sending are 1 row updates to a heartbeat table and the streams pools are a few hundred meg.
I have tried aq_tm_process unset, as well as set to 2 and the tables continue to grow.
The MSG_STATE in aq$tab are either DEFERRED or DEFERRED SPILLED. As mentioned all of the heartbeat updates ( as well as small test transactions ) replicate just fine, so the transactions are being captured,propagated and applied.
I am running 10.2.0.2 on solaris 10 with no streams related one off patches to speak of, for reference. My propagation did not specify queue_to_queue.
I'm wondering if there is a step I may have missed, or what else I may be able to look at to ensure that these tables are cleaned up?
Thanks.
Edited by: user599560 on Oct 28, 2008 12:39 PM

Hello
I forgot to mention that you should check v$propagation_receiver on the destination and v$propagation_sender on the source. v$propagation_receiver on the source will not have records unless you are using bi-directional streams.
The aq_tm_processes parameter should be set on all the databases that uses Streams. This parameter is responsible for spawning the number of queue monitor slaves which is actually performing the spilling and removing the spilled messages which are no longer needed.
It is suggested to remove this parameter from spfile, however your SHOW PARAMETER will still show this as 0. Hence you should be checking v$spparameter to confirm whether this was actually removed from it. If you remove it from the spfile, then it should spawn the required number of slaves automatically as per the autotune feature in 10g. However I would always suggest to set this parameter to 1 so that one slave process will be always spawned even if we dont use Streams and SHOW PARAMETER always show this as 1.
If you find the slaves are not spawned, then you should be checking your alert.log to see whether any errors are reported. You need to check the Queue Monitor Coordinator process qmnc is spawned. If qmnc itself is not spawned (by default it should be spawned always), then no q00 slaves will be spawned. If you remove the parameter from spfile and you see that no q00 slaves are spawned eventhough you are using Streams (either capture, prop or apply) then you should log an SR with Oracle Support to investigate this. You can check the qmnc and q00 slaves at the OS level using the following command:
ps -ef | grep $ORACLE_SID | grep [q][m0][n0]
Please mark this thread as answered if all your questions are answered well else let me know.

Old recovery points seems to not being cleaned up

I'm running a Windows Server 2012 server with DPM 2012 SP1, acting as a secondary DPM server for a couple of primary servers. However, the last 5-6 weeks it has begun to behave very strange. Suddenly, I get a lot of "Recovery Point volume threshold
exceeded", "DPM does not have sufficient storage space available on the recovery point volume to create new recovery Points" and "The used disk space on the computer running DPM for the recovery point volume of SQL Server 2008 database
XXXXX\DB(servername.domain.com) has exceeded the threshold value of 90% (DPM accounts 600 MB for internal usage in addition to free space available). If you do not allocate more disk space, synchronization jobs may fail due to insufficient disk space. (ID
3169).
All of these alerts seem to have a common source - disk space of course, but there is currently 8 TB free in the DPM disk pool. However, I have a feeling that all of this started when we added another DPM disk to the storage pool. Could it be that DPM doesn't
clean up expired disk data correctly any longer?

Hi,
If the pruneshadowcopiesdpm201.ps1 is not completing, hangs, or crashes, then that needs to be addressed as that will definitely cause storage usage problems.
In the meantime you can use this powershell script to delete old recovery points to help free disk space. It will prompt to select a datasource, then a date to delete all recovery points made before that time.

Passivation table ps_txn not being cleaned up

Adf 11gR1PS1
Hello
I have a samll application using one unbounded task flow and one bounded task flow.
Each task flow uses a different application module.
The unbound task flow calls the bounded task flow in a modeless inline-popup via a button.
When running the application and clicking on the button the bounded task flow is called and a new row is inserted
into the ps_txn table.
However when the inline-popup is closed via the "x" on the popup window the row is not removed from the ps_txn table.
If the button is clicked again a new row is added to the theps_txn table.
Is this the normal behaviour, looking at 40.5.3 in the Dev Guide it would seem that the record should be deleted or reused.
I understand that there are scripts for cleaning up the table but shouldn't it be automatic ?
What am I missing ?
Regards
Paul

Hi Paul,
Do you use the failover (jbo.dofailover) ?
If not, I would expect records to be deleted from PS_TXN at activation.
I tested with the ADF BC Component Browser, selecting menus Save/Restore Transaction State, with jbo.debugoutput=console:
[277] (0) OraclePersistManager.deleteAll(2126) **deleteAll** collid=17461
[278] (0) OraclePersistManager.deleteAll(2140) stmt: delete "PS_TXN" where collid=:1
[279] (0) OraclePersistManager.commit(217) **commit** #pending ops=1But I also already noticed orphaned records in the table.
Do you use jbo.internal_connection to use the same connection whatever the AM instance that's passivated/activated or do you have an instance of the PS_TXN table in all AM's connections ?
Regards,
Didier.

Memory optimized DLLs not being cleaned up

Hi,
From BOL, my understanding is that DBAs do not need to administer DLLs created for memory optimized tables, or natively compiled stored procedures, as they are recompiled automatically, when the SQL Server service starts and are removed when no longer needed.
But I am witnessing, that even after a memory optimized table has been dropped, and the service restarted, the DLLs still exist in the file system AND are still loaded into SQL memory and attached to the process. This can be witnessed by the fact that they
are still visible in sys_dm_os_loaded_modules, and are locked in the file system if you try to delete them, whilst the SQL Service is running.
Is this a bug? Or are they cleaned up at a later date? If at a later date, what triggers the clean-up, if it isn't an instance restart?
Pete

Most likely the DLLs are still needed during DB recovery, as there are still remnants of the tables in the checkpoint files. A couple of cycle of checkpoints and log truncation (e.g., by doing log backup) need to happen to clean up the old checkpoint
files and remove the remnants of the dropped tables from disk.
The following blog post details all the state transitions a checkpoint file goes through:

In a past thread, it mentioned that we may try to use various SDK code offerings to manage sessions. Could you provide some sample codes using CRS SDK or CMS configuration to release the sessions.
Here is the codes:
try

reportAppSession.createService("com.crystaldecisions.sdk.occa.report.application.ReportClientDocument");
reportAppSession.setReportAppServer("myCRServer");
// This is where the exception is thrown.
reportAppSession.initialize();

lo_ReportClientDoc.setReportAppServer(reportAppSession.getReportAppServer());
lo_ReportClientDoc.open(asReportName,OpenReportOptions._openAsReadOnly);

Recommendation is to publish the report to the Server, and use managed reporting.
You'd have more control over the EnterpriseSession that way.
Unmanaged RAS does use the Guest account for logon, and you don't have any control over the EnterpriseSession at all.
It would be better to upgrade the CAL licensing, if you require additional users.

Expired updates not being cleaned up

Hi,
I've been trying to clean up old expired updates on my SCCM 2012 SP1 server and for whatever reason it seems that the updates files are never actually getting removed.
At first I tried the instructions at
http://blogs.technet.com/b/configmgrteam/archive/2012/04/12/software-update-content-cleanup-in-system-center-2012-configuration-manager.aspx
When I run the script they provide it appears to go thru all the updates but never actually deletes any of them. The script always seems to say found it found an existing folder and then later it says that that it is excluding the same folder because
it is active.
Then I read that SP1 for SCCM 2012 is actually supposed to do the clean up process automatically. But in this case do I need to do anything like expire the updates manually or does SCCM now do that? How can I see what is preventing either
the manual script or the automatic clean up process from actually removing the unneeded files and folders?
And does anything need to be done with superseded updates as well?
Also I've always thought that when you SCCM 2012 to do your updates that you should never go to the WSUS console and do anything but I read
http://blog.coretech.dk/kea/house-of-cardsthe-configmgr-software-update-point-and-wsus/ and he is going the WSUS console and doing a clean up there as well.
Thanks in advance,
Nick

So it seems like it might be skipping updates? And then it says it deleted 168 expired updates for example?
But if I look at the drive where all the update packages are stored it hasn't changed size.

JRun session id being re-used

We are using JRun 4.0 on our server in conjunction with MS
IIS 6.0 to support dynamic JSP pages and Java Serlvets. We are
using URL Encoding to support session handling. In the jrun-
web.xml file we have the following parameters to disable the use of
cookies for session handling.
<session-config>
<cookie-config>
<active>false</active>
</cookie-config>
</session-config>
With these parameters defined in the jrun-web.xml file, and
the use of response.encodeURL() function, we see that jrun
automatically appends a jsessionid=xxxxxxx parameter in the urls.
This has been working for us well since long. Recently we noticed
that these jsessionid values are being re-used by jrun for
different session instances. Which means if a user logs in to a
website at a given time and is assigned a sessionid say for e.g.
101011 and after a while the user logs out. After some time if
another user logs in, this second user is assigned the same
sessionid parameter (which has a value 101011) for handling his
session. If in case the first user has bookmarked the a page on the
website, the bookmark is going to include the sessionid parameter
(which has a value 101011) and if the first user accesses the
website from the bookmark at the same time as the second user is
logged in, the first user will get access to the second user's
session which is very unsecure.
This phenomena is referred to as session fixation and can be
used by a hijacker to get access to any other user's session. Is
there a way to prevent JRun from re-using these session id values
or to increase the time period after which JRun re-uses these
session ids.

Deny a returning paying(!) customer his session? Yours might be the only shop in town doing that.
If your session housekeeping is any good, then the session variables pertaining to shopping-cart, payment and delivery would have been cleared or re-initialized. Often, starting a new session means logging in again. There are a number of reasons why that can be undesirable.
I did an e-commerce course for a year, and learned some strange things. It is in fact to your advantage that a returning customer should keep his session, even after ordering.
For example, it is well known that the chances of a returning customer placing a new order is much higher when he is already logged in than when he has to log in afresh. You could test that hypothesis yourself. Psychologists have also found that e-shoppers often return to the shop to gloat at the goodies they've just ordered. You wouldn't want to deny them their gloating session, would you?

I have had a similar problem with my system. I just recently (within a week of this post) built a brand new desktop. I installed Windows 7 64-bit Home and had a clean install, no problems. Using IE downloaded an anti-virus program, and then, because it was the latest version, downloaded and installed Firefox 4.0. As I began to search the internet for other programs to install after about maybe 10-15 minutes my computer crashes. Blank screen (yet monitor was still receiving a signal from computer) and completely frozen (couldn't even change the caps and num lock on keyboard). I thought I perhaps forgot to reboot after an update so I did a manual reboot and it started up fine.
When ever I got on the internet (still using firefox) it would crash after anywhere between 5-15 minutes. Since I've had good experience with FF in the past I thought it must be either the drivers or a hardware problem. So in-between crashes I updated all the drivers. Still had the same problem. Took the computer to a friend who knows more about computers than I do, made sure all the drivers were updated, same problem. We thought that it might be a hardware problem (bad video card, chipset, overheating issues, etc.), but after my friend played around with my computer for a day he found that when he didn't start FF at all it worked fine, even after watching a movie, or going through a playlist on Youtube.
At the time of this posting I'm going to try to uninstall FF 4.0 and download and install FF 3.6.16 which is currently on my laptop and works like a dream. Hopefully that will do the trick, because I love using FF and would hate to have to switch to another browser. Hopefully Mozilla will work out the kinks with FF 4 so I can continue to use it.
I apologize for the lengthy post. Any feedback would be appreciated, but is not necessary. I will try and post back after I try FF 3.16.6.

Ipod not being recognised, but with a twist

Hi,
My ipod nano 5th Gen is not being recognised on my computer. It is now being recognised by the computer itself sometimes, but not itunes. However, when I plug my ipod into my partners laptop, its fine. More to the point, when they plug their's into my laptop, it recognises them. To me, this suggests that both my laptop and my ipod, individually at least, are working.
I have been through the ipod support page, and gone through all the steps, and to no avail.
Final details. I'm Windows 8, and my itunes is totally up to date. I have re-installed iTunes, and have reset my ipod to factory settings on another computer. It still doesn't work, please help if you know anything about this!!
Cheers,
Ralf

I have the same issues. itunes 5.0.1.4 doesn't recognize my mini. ipod updater doesn't recognize my mini either. i have uninstalled itunes 5 and reinstalled 4.9, but it didn't work still. something in itunes 5 changed something in my system that reinstalling 4.9 doesn't fix it. updater just shows that i have no ipod connected. if i try to get updater to check for my ipod during the updater installatin, it just sits there and says "waiting for ipod". it's not my usb port because i can read and write to my ipod. i did the entire list of chores that apple suggests on the site including disabling all other functions and services, reinstalling the com port, uninstalling everything, reinstalling everything, getting windows install clean up, e v e r y t h i n g! nothing worked.
I then installed itunes 4.9 and updater 1.4 in my other laptop. i was able to update to firmware 1.4 using that computer. when i put the ipod into that computer w/ itunes 4.9, everything works fine. of course, it asks me if i want to link that laptop w/ my ipod. i said no, because i want to use my original laptop w/ the ipod.
anybody have a solution for this? it's like we all have the same symptoms and going to the same doctor and we end up having to diagnose ourselves. this is extremely annyoying and inefficient.

16 rows selected.But, then, I tried this too.
SQL> alter session set "_fast_full_scan_enabled"=true;
Session altered.
SQL> SELECT MAX(edi_end_date),
2         org_id,
3         partnerid
4    FROM hug_data
5   GROUP BY org_id,
6            partnerid;
MAX(EDI_E     ORG_ID PARTNERID
2 rowsAnd this took around 5 minutes too.
PS: This has nothing to do with original question, but, it is plausible to derive the 'huge_data' table name from the sql_id? Just curious.
