ADS timeout and hanging

Looking for forum points? Then you came to the right place! The more points I give out on this one, the better!
I've got a problem where ADS seems to hang and time out.
From ABAP (ECC 6.0), transaction SE38:
Program FP_TEST_00
Program FP_CHECK_DESTINATION_SERVICE
Hangs in FM HTTP_READ_SC "system-call plugin..."
From Java (NW04s):
Manager Self-Service -> Team -> Create New Personnel Change Request -> Edit Form
Read timed out
com.sap.tc.webdynpro.clientserver.adobe.pdfdocument.base.core.PDFDocumentRuntimeException: Failed to UPDATEDATAINPDF
The defaultTrace file (\usr\sap\<sid>\JC<inst>\j2ee\cluster\server<inst>\log) says this when it is hanging:
<b>Begin RenderAll CORBA call to XMLFormsModule
Initializing the CORBA XMLForm Module factory</b>
Any ideas? ADSUser seems to be set up fine. (Program FP_PDF_TEST_00 works fine from SE38.)
Although the "http://<server>:<port>/AdobeDocumentServices/Config" test returns a weird error:
Exception in method rpData.
I'm just not sure what to try next. I have been following the "Adobe Document Services Configuration Guide":
http://help.sap.com/saphelp_nw04s/helpdata/en/34/783241baebf323e10000000a155106/frameset.htm

Got it!
I upgrade to ADSSAP 7.1:
Version 710.20061024154505.342190
Note 1072218
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/oss_notes/sdn_oss_bc_wd/~form/handler
That seems to have solved the timeout problems, and things are rendered correctly now!

Shell Script: Timeout and return error if Sqlplus hangs

Shell Script: Timeout and return error if Sqlplus hangs
Dear all,
This morning, our production database hung with lots of ORA-600 and 7445. The issue has been escalated to Oracle Tech support but my monitoring script which tries to make a connection every 5 mins to the database to see if its up, did not alert me. The reason is that, it connected to the database and hung, never came out to report an error and so I never got alerted until a user called me.
Can any one tell me how I can exit from the sqlplus block if I dont get a response in x seconds? This sqlplus block is being called with in a shell script.
Any help is highly apprciated.

I don't know of anything built into any shell scripting language that would do this, no. I'm not a Perl programmer, but I have a vague recollection that Perl may have something useful here.
From the "separate thread" part of my comment, though, you could certainly spawn a separate thread (thread 2), have thread 2 wait a period of time, then look for a message from thread 1 and throw an error if the message hadn't been sent. I don't know that I'd be for writing multi-threaded shell scripts, though. The heartbeat also gives you a layer of redundancy so that something is monitoring the monitor in case that process stops working.

Database connection timeouts and datasource errors

Connections in the pool randomly die overnight. Stack traces show that for some reason, the evermind driver is being used even though the MySql connection pool is specified.
Also, the evermind connection pool is saying connections aren't being closed, and the stack trace shows they're being allocated by entity beans that are definitely not left hanging around.
Sometimes we get non-serializable errors when trying to retrieve the datasource (this is only after the other errors start). Some connections returned from the pool are still good, so the application limps along.
EJBs and DAOs both use jdbc/SQLServerDSCore.
Has anyone seen this problem?

Rick,
OC4J 9.0.4.0.0 - BTW, do you know of any patches?As far as I know, there are no patches for the 9.0.4
production version of OC4J stand-alone.
I'm using container managed persistence,It was not clear to me, from your previous post, that you
are using CMP entity beans.
I found staleness-timeout and alive-poll-query
somewhere on a website when trying to track this
down. Here's four sources:Those sources refer to OrionServer -- and an older version, too, it seems.
Like all other Oracle products that start out as somebody
else's -- including, for example, JBuilder (that became "JDeveloper"), Apache Web Server (that became "Oracle HTTP Server") and TopLink -- their development paths diverge, until, eventually, there is absolutely no similarity between them at all. Hence, the latest versions of OC4J and "OrionServer" are so different, that you cannot be sure that something that works for "OrionServer" will work for OC4J.
I recall reading something, somewhere, sometime about configuring OC4J to use different databases (other than Oracle), but I really don't remember any details (since it was not relevant to me, because we only use Oracle database). In any case, it is possible to use a non-Oracle database with OC4J.
Good Luck,
Avi.

Session Timeout and Dynamic Actions

Did anybody ever use the Session Timeout feature in APEX successfully?
I have set an idle session timeout and provided an url to redirect to once the session is expired: Home > Application Builder > Application nnn > Shared Components > Edit Security Attributes > Session Timeout
It works so far during the page rendering and page processing phase. But I have major problems with dynamic actions and custom ajax requests.
Dynamic actions will just hang and simply don't return. Even worse, when I execute the dynamic action once the session is expired, the session seems to be physically deleted and thus the next click on a tab will not redirect to the expiration page but go straight to the login page.
Did anybody make it work or is the best way to implement a custom session timeout?
Thanks,
Dietmar.

Hi All,
Check out the Session Timeout plug-in available here:

Let me know if that helps.

Process chain executed synchronously produces dump and hangs

Process chain (RSPC) being executed synchronously hangs on a step (not first) with yellow status. Analysis of ST22 shows there is dump: RAISE_EXCEPTION
The chain loads data from flat files on frontend to several characteristics (attributes and texts). All the steps are sequential.
After the start first file is loaded successfully (info package), subsequent data transfer process has no errors too. But the second info package becomes yellow and hangs just after ( after some time timeout occurs and the step becomes red). In ST22 i see dump, text of the dump is below. Analysis of the dump reveals that 'GUI_UPLOAD' FM doesn't work during execution of the second info-package.
The chain looks as follows:
1. Info package 1
      V
2. Data transfer process 1
      V
3. Info package 2              <-------   hangs here because of dump
      V
4. Data transfer process 2
     V
Hangs on step 3 (infopackage 2).

If i load the step manually it works. The hung step is possible to re-execute after it gets red (with context menu) and it works then. After that it hangs on the 3rd info-package and so on.
The file lays on a network drive, but i suspect it doesn't matter

Hi Jane, Thanks for the reply. I have now purchased an AEBS(n) to try to overcome this problem. The Apple site says it is compatible with all versions of Airport card so I thought it would solve the problem. My new problem is to be found here: http://discussions.apple.com/thread.jspa?threadID=1087292&tstart=0
However to answer your questions, The OS is 10.4.10 and I have run every updater I can find for all Macs concerned. hope this helps.

Re: timeouts and ExternalConnection

Tim,
Use a Timer class of Framework library to have an explicit control over
the connection. If the end-of-stream marker is not received within a
specified interval of time, handle the situation.
ExternalConnection class does not have any timeout feature of its own,
but it would be a good idea to have one in future.

Please respond to Tim Kannenberg <[email protected]>
Subject: timeouts and ExternalConnection
I am working on a Forte service that uses a socket listener (implemented
using the ExternalConnection class) to handle incoming messages. The
messages vary in length, so the code for processing each connection
loops until it finds an end-of-stream marker. If some client is
erroneously sending messages without the marker, it'll loop forever. I
would like the connection to time out if it doesn't receive any valid
messages within a fixed length of time. Is there some functionality
I've overlooked in ExternalConnection that would handle this? If not,
does anybody have an example of a good way to implement it?
Thanks in advance,
Tim

I've re-run the speed test. Here they are. Download speedachieved during the test was - 19915 Kbps For your connection, the acceptable range of speedsis 12000-29036 Kbps . Additional Information: IP Profile for your line is -29036 Kbps Upload speed achieved during the test was - 3819 Kbps Additional Information: Upstream Rate IP profile on your line is - 10000 Kbps Although the speed has dropped markedly since Saturday, its the dropouts, the VPN unable to connect and the slow respnses when trying to connect to websites quickly (DNS issue?) that is bothering me. It's not just one website that the problem is with, its any.

Frequent timeouts and poor performance

Hello,
Starting this morning I'm experiencing a lot of timeouts and performance issues with my SQL Azure DB (located in West US), causing several Azure hosted services to fail. I've checked everything I can think of and it nothing shows a clear problem with our
databases. I'm not seeing anything on the dashboard, but can't help but wonder if there is an issue going on that hasn't been detected.
Any suggestions on how to troubleshoot this issue?
Thanks,
-Fabio

Hi Fabio,
I work on the Cotega monitoring service for SQL Azure and I can also confirm that we saw a few customer who we notified of performance issues with SQL Azure as well.
Now that I write this, I am wondering if it might be worth adding to the service a page that lets anyone see the historical performance of SQL Azure based on aggregated data from all of the customers databases that we currently monitor. I wonder if
that would be useful for situations like this?

SQL Timeouts and Blocking Locks

SQL Timeouts and Blocking Locks
Just wanted to check in and see if anyone here has feedback on application settings, ColdFusion settings, JBOSS settings or other settings that could help to limit or remove SQL Timeouts and blocking locks on SID's.
We're using MS SQL 2000 with JBOSS and IIS5.
We've been seeing the following error in our logs that starts blocking locks in SQL:
java.sql.SQLException: [newScale] [SQLServer JDBC Drive] [SQLServer] Lock request time out period exceeded.
Once this happens, we're hosed until we remove the blocking SID in SQL. These are the connections to the application.
Any feedback would be great. Thanks!

Hi
This is your exact solution:
Select a.username, a.sid, a.serial#, b.id1, c.sql_text
From v$session a, v$lock b, v$sqltext c
Where b.id1 in( Select distinct e.id1
from v$session d , v$lock e
where d.lockwait = e.kaddr ) and
a.sid = b.sid and
c.hash_value = a.sql_hash_value and
b.request =0;
Thanks

Session timeout and custom sso

Hi,
can anyone tell me how the session and idle timeout feature in Apex exactly works?
I built several applications in a workspace and do a sso authorization by setting a common cookie name. In addition to that i set the values for session length and idle timeout and assumed that the session length would be synchronized over all applications. But this doesn't seem to work. For instance, i set the idle timeout to 10 minutes in all applications and now i work for 15 minutes continously in application A and after that i switch over to application B (using the same session id!), the session is already expired in B.
Is this behavior correct? And, if yes, how can i set up a synchronization over all applications?

Is there a risk of setting a console connection timeout and what is the recommended setting?

Is there a risk of setting a console connection timeout and what is the recommended setting? Please suggest if there is any best prctice documentation that can be referred.

Hi Henrik
depend on what you need or what your security policy says for my lab gear i use 60 minutes. because i know how can access this. if you have gear outside in insecure space set it to a minimum or disable the console. everybody how can access your gear can break in. simple restart and boot w/o config. and you are in.
it realy depends how secure is your space and how much security you need.
and than the settings for policy have to match, what sec do you have if your console login and logout is secure. but when you restart you can simple break in by starting w/o config and than load it.

What is the difference between Session timeout and Short Session timeout Under Excel Service Application -- session management?

Under Excel Service Application --> session management; what is the difference between Session timeout and Short Session timeout?

Any call made from the API will automatically be set to the “Session Timeout” period, no matter
what. Calls made from EWA (Excel Web Access) will get the “Short Session Timeout” period assigned to it initially.

BPEL - Handling invocation timeouts and Modifying Partner Link endpoints

Hi,
We've built the basic functionality that we need in our BPEL process but are facing 2 specific questions that we are a bit stuck with and would really appreciate some help on..
1. Our BPEL process calls an external synchronous web service. We have a requirement that if this external web service is unable to respond to our BPEL process within a fixed timespan (say 1 minute), we need to treat this as a timeout and move on. Can anyone suggest what settings are required for this?
2. The second query is with regards to a likely situation we will face after go-live. If the URL of the external service changes (lets say the service moves from one server to another), ideally we would want to be able to configure this URL change rather than have to modify the WSDL and rebuild the BPEL project in JDev with the new WSDL. Does the BPEL Admin Console provide any such feature? As far as I can recall from a project a couple of years ago, Websphere Process Server did provide such a feature and I'm looking for something similar here but have not found it yet. I am not looking to use dynamic endpoints within our flow - just for an admin feature that would allow me to modify the URL externally via the console.
Would really appreciate any suggestions on these 2 points..
Thanks and Regards,
TB

In response to your second query -
a) you don't need to rebuild the BPEL project in Jdev in order to change the wsdl file. If you update the WSDL file with new values for your endpoint simply clear the WSDL cache and the process will pick up the new values in the new instances created from thereon.
b) or if you dont' want to update the wsdl manually, you can write a piece of java code to change the endpoint URL's for the deployed BPEL processes using the code given here

Azure Scheduler Job Timeouts and Retries?

We have a WEBAPI running outside of Azure and want to schedule one of the methods with Azure. It loads data from SharePoint Online into an SQL database on-Prem. It can take 15 minutes to complete. I'm doing a GET call to the URI, but
it reports it's FAILED timing out and retrying... from our SQL logs the job appears to complete, though not clear if it ran multiple times. Any way to fix this? No way to adjust timeout and retries in Azure job Scheduler?

Hi,
It looks like you are using the Azure Scheduler service, not the Azure Automation service. Is that correct? This forum is only for the Azure Automation service.
If so, I will move this thread to the Scheduler forum.

Session timeout and Custon login module

Hi,
Dev Platform: Jdev 10.1.3.4.0, Oracle 10.2.4
I'm trying to trap the session timeout and display a page. I'm using the code below from Frank Nimphius. I've also provided a console log of what is happening when the application times out. Instead of the filter being called the system is calling the dblogin module and attempting to login the anonymous user. I renamed the anonymous user and I just see log entries where the system attempted to find the anonymous user.
If I use the application to logout I get a Logout page with a button to confirm the logout. When I press the button the session is invalidated and the filter code brings up my "Session Timeout" notification page. This isn't what will happen in the end but I just wanted to tell you that the filter does work in certain instances.
How can I make the system not attempt to login the anonymous user and have the filter code run?
TIA, Dave

I added an HttpSessionListener upon login here's what I get:
09/03/31 08:21:25 Inside sessionCreated
09/03/31 08:21:25 Before New session createb = 0
09/03/31 08:21:25 Created session id: 854b4b95cf28ceb065d0489a31ee79c19feabb80716f6d828b77fc7044b210bf
09/03/31 08:21:25 After New session count = 1
At session timeout here's what I get:
09/03/31 08:23:27 Count before destroyed = 1
09/03/31 08:23:27 Destroyed session id: 854b4b95cf28ceb065d0489a31ee79c19feabb80716f6d828b77fc7044b210bf
09/03/31 08:23:27 Count after destroyed = 0
09/03/31 08:23:27 Inside sessionCreated
09/03/31 08:23:27 Before New session createb = 0
09/03/31 08:23:27 Created session id: 854b4b95cf28ceb065d0489a31ee79c19feabb80716f6d828b77fc7044b210bf
09/03/31 08:23:27 After New session count = 1
Notice that the session Id in each case is IDENTICAL. That is why the Filter code isn't doing what it is intended to do. Whay is the same session ID being created after it is destroyed? Is there a configuration parameter that controls it?
Thanks,
Dave
