I'm refactoring a very old reports generating function in an ORACLE web application. It used JavaScript to construct a URL, sending to the reports server to run a reports. What I want to do is processing it in the database, in PL/SQL procedures(invoked through mod_pl/SQL). I tried to use utl_http.begin_request to do that, but sometimes when the output file is large(PDF format, about 20 pages, 1.5M), I received an error:
ORA-29259: end-of-input reached.
The test codes for sending requests are quite simple:
--------upgraded 2013/08/27----------------------------------------------------------
UTL_HTTP.set_transfer_timeout(1000);
--some params setting....
myIdent := SRW.RUN_REPORT(myPlist); --here raise the exception(ORA-29273:request_failed; ORA-29259: end-of-input reached.) and procedure stoped.
r_stat := SRW.report_status(myIdent,myPlist);
#ThinkJet, Thanks for your help.
I logon the report server, found that the report still running after I got this exception in my program, and finally finished succefully.I tested for many times, and found everytime I got the exception just 5 minutes after I started request,no matter what kind of reports I was running and what size it was (sure, all big size,running for over 5mins).I'm wondering if it's something about configuration on oracle application server?
Does anyone have idea about this? Many Thanks.
ORA-29259 while SRW.RUN_REPORT
is ias 10g , this is cause by httpd.conf timeout parameter configuration
just
1.edit $ORACLE_HOME /Apache/Apache/conf/httpd.conf
change "Timeout" great than your report running time
2.restart http server and test it.
opmnctl restartproc ias-component=HTTP_Server
It take a time on Oracle Reports side to produce a big reports so a timeouts can occur sometime. Try to increase timeout with utl_http.set_ransfer_timeout procedure before originate a request and look if it helps.

We've one IIS application server on which we have deployed ASP.NET application.
Now the issue is Server is hanging very frequently and every time we are recycling or restarting application pool. Could you please help me to fix it.
What I've tried:
1) Looked into IIS log and found that there are few requests throwing 500 error some time. All the time except few instances same requests are working fine and getting 200 status.
2) Few resources are taking longer time like
a) "Report.aspx" - State- SendResponse - Time Elapsed- 2-3 minutes
I checked the query and found that sp is returning data in 00:00:02.
b) "NewReport.aspx" - State- ExecuteRequestHandler- Time Elapsed- 1 minutes
I checked the query and found that sp is returning data too quickly.
3) Default recycle time is 29 hrs, and each application is using individual pool.
4) In code application connection has been opened and not closed at very few places.
5) We are using connection pooling, having 2 different connection string with Max Pool=500 and min Pool=50 each.
6) Most of the time there is no error in Event Viewer, some time have received TCP/IP error.
What I am looking for:
1) Do I need to make any changes in IIS to track down or please help if any changes required in IIS?
2) Is there any setting in SQL Server which can help me to find out or fix it?
3) Please help if anything else I've to do to fix this issue from your previous experiences.
I think you should capture a hang dump for W3WP.exe with Procdump or debug diagnostic tool first. We need to check all managed stack trace via WINDBG, sos.dll and mex extension. So that we can figure out worker thread is pending on which method and which module. Then might tell us about how to fix this hang issue. If you could find a way to always reproduce this problem. The problem would become much easier.
This link is about how to capture hang dump.

If you don't know how to analyze dump file manually, debug diagnostic analysis tool could help you achieve this.
I cannot seem to figure out this issue. I have a qlikview document that pulls in a bunch of data and aggregates/joins it up. Typical qlikview stuff. At the end of my process I have an oracle stored procedure call. I am not retrieving anything back. This is a simple call to a database to trigger a process. I have setup my ODBC connection and User DSN on my local machine for the connection. When I run my qvw file on my local machine everything works just fine. The proc call is made and the script executes without any errors.
However, when I put the document on our reload server and after I setup a reload task for it the process throws a general script error when the sql proc is called. What could cause this? The user running the document has execute permissions. Do I need to setup a DSN on the reload server?
Really not sure at all here. Hopefully someone here can help me out. Thanks.
Unfortunately QlikView's SQL error messages are not that helpful for debugging purposes. In this case you can try turning on ODBC logging (http://support2.microsoft.com/kb/274551) and then reload the script to try and capture the cause of the error.
Finally, if your script refers to a "local" DSN then this also needs to be present on the machine that will perform the reload, in this case the QlikView server.
We have a new beta version of our software with some changes, but not around our database layer.
We've just started getting Error 3128 reported in our server logs. It seems that once it happens, it happens for as long as the app is open. The part of the code where it is most apparent is where we log data every second via SQLite. We've generated 47k errors on our server this month alone.
3128 Disk I/O error occurred. Indicates that an operation could not be completed because of a disk I/O error. This can happen if the runtime is attempting to delete a temporary file and another program (such as a virus protection application) is holding a lock on the file. This can also happen if the runtime is attempting to write data to a file and the data can't be written.
I don't know what could be causing this error. Maybe an anti-virus program? Maybe our app is getting confused and writing data on top of each other? We're using async connections.
It's causing lots of issues and we're at a loss. It has happened in our older version, but maybe 100 times in a month rather than 47,000 times. Either way I'd like to make it happen "0" times.
Possible solution: Exception Message: Some kind of disk I/O error occurred
Summary: There is probably not a problem with the database but a problem creating (or deleting) the temporary file once the database is opened. AIR may have permissions to the database, but not to create or delete files in the directory.
One answer that has worked for me is to use the PRAGMA statement to set the journal_mode value to something other than DELETE. You do this by issuing a PRAGMA statement in the same way you would issue a query statement.
PRAGMA journal_mode = OFF
Unfortunately, if the application crashes in the middle of a transaction when the OFF journaling mode is set, then the database file will very likely go corrupt.1.
1 http://www.sqlite.org/pragma.html#pragma_journal_mode
The solution was to make sure database delete, update, insert only happened one at at time by wrapping a little wrapper. On top of that, we had to watch for error 3128 and retry. I think this is because we have a trigger running that could lock the database after we inserted data.
I am currently trying to get search working in my Tridion 2011 installation. I read in another article that I should run the TcmReIndex.exe tool in the Tridion/bin folder to re-index all my sites. So I tried this and it failed with a message box giving the following details
Unable to get list of Publication items.
Unable to Intialize TDSE object.
The wait operation timed out
Connection Timeout Expired. The timeout period elapsed while attempting to consume the pre-login handshake acknowledgement. This could be because the pre-login handshake failed or the server was unable to respond back in time. The duration spent while attempting to connect to this server was - [Pre-Login] initialization=21054; handshake=35;
The wait operation timed out
A database error occurred while executing Stored Procedure "EDA_TRUSTEES_GETTRUSTEEETOKEN"
I have four fairly large publications (100 000+ items in total) which I am trying to index.
Any ideas?
Whenever I get "Unable to Intialize TDSE object." errors, I typically write a small test script using VBScript, and try running it on the CMS server. Whilst this does not directly solve the problem, it often gives some insight into the issue by logging information in the event viewer. Try creating a test.vbs file as follows and running it:
Set tdse = CreateObject("TDS.TDSE")
tdse.initialize()
msgbox(tdse.User.Description)
Set tdse = Nothing
If it throws any errors, please let me know, and it may help us solve the problem. If it gives you a popup with your user description, then I am completely barking up the wrong tree.
I haven't come to anything conclusive but it seems like my issue may have been a temporary one as it just started working. I did increase all timeouts in Tridion MMC > Timeout Settings by 100 times their amounts but I suspect that this wasn't the issue, when it works the connection is almost instant.
If anyone else has this issue
Restart the computer the content manager is installed on, try again.
Wait an hour or two, try again.
Increase timeouts, try again.
I've run the process a few more times and it seems to be working correctly.
My site is running under IIS correctly. But after working for long time. It start giving the timeout error, seems like sever busy in doing other work. But the SQL server is running in my local host with no server usage/load except of the current application.
"Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding."
After doing the system restart only i can resume my work. Need help on this. Thanks in advance
It sounds like you're hitting the execution timeout. If you're reaching this threshold, you may want to do some profiling to see if there's a performance bottleneck somewhere. To work around this issue, you can specify an execution timeout in the web.config:
<httpRuntime executionTimeout="180" /> <!-- in seconds -->
To change the execution timeout in SQL Server go to the server properties:

See here for more details:
Changing the CommandTimeout in SQL Management studio
I have used the recompile to solve this issue.
EXEC sp_recompile N'myproc'
Finally resolved this issue by clearing out the execution plan from the procedure cache.
To clear the plan cache run the following scripts...
SELECT plan_handle, st.text
FROM sys.dm_exec_cached_plans
CROSS APPLY sys.dm_exec_sql_text(plan_handle) AS st
where objtype = 'Proc' AND st.[text] like '%[Enter stored procedure name here]%'
If the stored procedure exists in the cache you're results should look like this:
From the results returned replace the plan_handle in the example below...
-- Remove the specific execution plan from the cache.
DBCC FREEPROCCACHE (0x050017005CBF201940A1CE91000000000000000000000000);
GO
