Writing to servlet log files?

Using the log(...) method of the servlet API. No problem finding the log file in the case of the embedded server in JDev. I cannot find the log file in the standalone OC4J. Seems to me there is an XML attribute to 'turn-on' to enable logging but I do not remember it.
Please send me info to enable logging -
THANKS - Ken Cooper

The string written to standalone log file does not exist anywhere in the JDev installation folder!Do you mean your oc4j standalone installation is inside you Jdev installation? I am so confused.
As far as I checked, the servlet log(...) should go to the log file for the j2ee application, which is by default, application.log in application-deployments/yourApp directory. It did in my simple test.

Reading and Writing to a Log file

Hello,
I'm writing a class that will write a user id to a log file every time they click on a particular button. However, I don't want a new line every time a user clicks on the button, I'd like to be able to find their id in the log, increment a counter and write that back to the log in place of the previous entry.
For example, User A clicks on the button for the first time so I write in the log:
User A 1
Next time they come along, I want to see if User A exists in the log - which they do - add 1 to the counter and replace User A 1 with User A 2. So the log will now say:
User A 2
I was thinking of writing to the log, reading the log back in to a HashMap and then writing the HashMap out every time. Seems like a rather inefficient solution. Is there anything else I can do?
Thanks!

Hi,
counters are a standard topic. Many solutions are to be found in
textbooks. Here is one of them (Hunter & Crawford Java Servlet
Programming):
String activeUser = ... ;
try
FileReader fileReader = new FileReader( "mylog" );
BufferedReader bufferedReader = new BufferedReader(fileReader);
FileWriter fileWriter = new FileWriter("mylog.new");
BufferedWriter bufferedWriter = new BufferedWriter( fileWriter );
String line;
String user;
String count;
while((line = bufferedReader.readLine() != null )
    StringTokenizer tokenizer = new StringTokenizer( line );
    if( tokenizer.countTokens != 2 ) continue; // bogus line
    user = tokenizer.nextToken;
    if( activeUser.equals( user ) )
      count = tokenizer.nextToken;
      bufferedWriter.write(user+" "+(Integer.parseInt(count)+1)+"\n" );
    else
      bufferedWriter.write( line );
bufferedWriter.close();
fileWriter.close();
bufferedReader.close();
fileReader.close();
File oldLog = new File("mylog");
File newLog = new File("mylog.new");
newLog.renameTo(oldLog);
catch( Exception e )
    // do whatever appropriate
}Have fun,

SQLScript , writing messages to log file

Hi,
We're developing SQLScript and executing them directly on Unix via Unix command HDBSQL. We use the -o keyword with HDBSQL to write messages like comments, custom errors into a log file. The only way we know how to force custom messages into the log file is the SELECT "Text" FROM DUMMY.
Now our SQL consists of multiple procedures that may be called in a nested fashion i.e Proc 1 calls Proc 2 which in turn calls Proc 3. We noticed that the SELECT FROM DUMMY way of writing comments into the log only works if the procedure is the first procedure in the line of nested calls(Proc 1). SELECT FROM DUMMY from a sub/nested procedure does not make it to the log file.
Is there any other way we can achieve this? Other DBs have options like DBMS.output which work well in such scenarios.
I would like to thank this group for being ever so helpful in all the issues we have faced so far.
Regards,
Nehal

Hello,
I do not agree. have you taken a look at Oracle9i Supplied PL/SQL Packages and Types Reference?
You can use UTL_FILE and DBMS_OUTPUT to achieve exactly what you want.

Writing messages to log file from database procedures

Folks,
Is there a way by which I will be able to write messages from a database procedure to a log file? I would like to know what a procedure is doing and if it has failed or suceeded just as we do in a Unix shell script where we can direct messages to a file.
e.g. echo 'step 34 completed' >> $X_LOG
Is there a log file in Oracle where we can check if a procedure has failed and what was the error. I am using Oracle 9i.
Thanks.

Writing to a log file.

I have written the following code. Also, by going through
the archives, many have written the similar way and were successful. The problem I have is, the log file is empty. Where am I missing something?
Thanks

<code>
import java.util.Calendar;
import java.io.*;
public class debugTest{
public static void main(String args[]) throws Exception {
String logFileDirString = "C:\\projects\\javaapp\\log\\tradematch\\";
String logFileName = getLogFileName(logFileDirString);
System.out.println("The log file name" + logFileName);
File logFileDir = new File(logFileDirString);
if (!logFileDir.exists()){ logFileDir.mkdirs(); }
File logFile = new File(logFileName);
if (!logFile.exists()){ logFile.createNewFile(); }
FileOutputStream fops = new FileOutputStream(logFile.getName(), true);
PrintStream ps = new PrintStream(fops);
System.setOut(ps);
System.out.println("Line 1");
System.out.println("Line 2");
ps.close();
public static String getLogFileName(String logFileDirString) {
Calendar rightNow = Calendar.getInstance();
//Month is 0 based. Added 1 to make it 1 based. Subtracted by Calendar.JANUARY, so that
//it takes care if it ever becomes 1 based.
Integer theMonth = new Integer((rightNow.get(rightNow.MONTH) + 1 - Calendar.JANUARY));
String theMonthString = theMonth.toString();
if (theMonthString.length() < 2) theMonthString = "0" + theMonthString;
Integer theDayOfMonth = new Integer(rightNow.get(rightNow.DAY_OF_MONTH));
String theDayOfMonthString = theDayOfMonth.toString();
if (theDayOfMonthString.length() < 2) theDayOfMonthString = "0" + theDayOfMonthString;
Integer theYear = new Integer(rightNow.get(rightNow.YEAR));
String theYearString = theYear.toString();
String theLogFileString = logFileDirString.concat(theMonthString).concat(theDayOfMonthString)
.concat(theYearString).concat(".txt");
return theLogFileString;

Use this:
<pre>
FileOutputStream fops = new FileOutputStream(logFile.getAbsolutePath() , true);
System.out.println( logFile.getAbsolutePath() );

Is there any downside to writing plain old log files?

Hi all;
We have our web & worker roles using log4net to write log files to disk. It works great where we then remote desktop in and go to the folder where they are and we've got exactly what we want - a daily log file for each worker.
Is there any downside to this approach?
Also, is there an easy way to have it delete all log files over a month old?
thanks - dave
What we did for the last 6 months -
Made the world's coolest reporting & docgen system even more amazing

hi dave,
If you stored the log file on instances disk, you may get them using the RDP. But if you redeployed ,auto-scaled the cloud service, the log file maybe removed. So I don't recommend you storage the content on Azure instances disk.
If you stored the log file on Azure Blob/Table storage (https://github.com/crossvertise/log4net.Appender.AzureBlobStorage/tree/master/TransactionLogger),
you could view it using some tool,such as Azure server explore and Azure storage Explore. And Azure storage will backup your storage data well.
>>Also, is there an easy way to have it delete all log files over a month old?
If you storage on azure storage, the one approach is that you could remove it manually . Another approach is that you could create a service on your project. And then you could create a Job using Scheduler service (http://msdn.microsoft.com/library/azure/dn479785.aspx
). If you don't like to use the Scheduler service, you could coding a delete log data or file method and execulted this method every day.

Writing data to log file

Is it possible to write data to a log (text) file from within Crystal Reports, possibly in a UFL? Is there a way that's already built in to CR?
Thanks.
Ron

Ido - thanks for the link. This will help.
Don,
Not exporting a report to a text file. More like logging report events. One of my report developers was thinking of maybe tracking the start/stop times of each publication per person as well as the full run time.
I hope I explained that correctly.
Thanks.

Reader 10.1 update fails, creates huge log files

Last night I saw the little icon in the system tray saying an update to Adobe Reader was ready to be installed.
I clicked it to allow the install.
Things seemed to go OK (on my Windows XP Pro system), although very slowly, and it finally got to copying files.
It seemed to still be doing something and was showing that it was copying file icudt40.dll. It still displayed the same thing ten minutes later.
I went to bed, and this morning it still showed that it was copying icutdt40.dll.
There is no "Cancel" button, so this morning I had to stop the install through Task Manager.
Now, in my "Local Settings\TEMP" directory, I have a file called AdobeARM.log that is 2,350,686 KB in size and a file MSI38934.LOG that is 4,194,304 KB in size.
They are so big I can't even look at them to see what's in them. (Too big for Notepad. When I tried to open the smaller log file, AdobeARM.log, with Wordpad it was taking forever and showing only 1% loaded, so after five minutes, I terminated the Wordpad process so I could actually do something useful with my computer.)
You would think the installer would be smart enough to stop at some point when the log files begin to get enormous.
There doesn't seem to be much point to creating log files that are too big to be read.
The update did manage to remove the Adobe Reader X that was working on my machine, so now I can no longer read PDF files.
Maybe I should go back Adobe Reader 9.
Reader X never worked very well.
Sometimes the menu bar showed up, sometimes it didn't.
PDF files at the physics e-print archive always loaded with page 2 displayed first. And if you forgot to disable the look-ahead capability, you could get banned from the e-print archive site altogether.
And I liked the user interface for the search function a lot better in version 9 anyway. Who wants to have to pop up a little box for your search phrase when you want to search? Searching is about the most important and routine activity one does, other than going from page to page and setting the zoom.

Hi Ankit,
Thank you for your e-mail.
Yesterday afternoon I deleted the > 2 GB AdobeARM.log file and the > 4.194 GB
MSI38934.LOG file.
So I can't upload them. I expect I would have had a hard time doing so
anyway.
It would be nice if the install program checked the size of the log files
before writing to them and gave up if the size was, say, three times larger
than some maximum expected size.
The install program must have some section that permits infinite retries or
some other way of getting into an endless loop. So another solution would be
to count the number of retries and terminate after some reasonable number of
attempts.
Something had clearly gone wrong and there was no way to stop it, except by
going into the Task Manager and terminating the process.
If the install program can't terminate when the log files get too big, or if
it can't get out of a loop some other way, there might at least be a "Cancel"
button so the poor user has an obvious way of stopping the process.
As it was, the install program kept on writing to the log files all night
long.
Immediately after deleting the two huge log files, I downloaded and installed
Adobe Reader 10.1 manually.
I was going to turn off Norton 360 during the install and expected there
would be some user input requested between the download and the install, but
there wasn't.
The window showed that the process was going automatically from download to
install.
When I noticed that it was installing, I did temporarily disable Norton 360
while the install continued.
The manual install went OK.
I don't know if temporarily disabling Norton 360 was what made the difference
or not.
I was happy to see that Reader 10.1 had kept my previous preference settings.
By the way, one of the default settings in "Web Browser Options" can be a
problem.
I think it is the "Allow speculative downloading in the background" setting.
When I upgraded from Reader 9 to Reader 10.0.x in April, I ran into a
problem.
I routinely read the physics e-prints at arXiv.org (maintained by the Cornell
University Library) and I got banned from the site because "speculative
downloading in the background" was on.
[One gets an "Access denied" HTTP response after being banned.]
I think the default value for "speculative downloading" should be unchecked
and users should be warned that one can lose the ability to access some sites
by turning it on.
I had to figure out why I was automatically banned from arXiv.org, change my
preference setting in Adobe Reader X, go to another machine and find out who
to contact at arXiv.org [I couldn't find out from my machine, since I was
banned], and then exchange e-mails with the site administrator to regain
access to the physics e-print archive.
The arXiv.org site has followed the standard for robot exclusion since 1994
(http://arxiv.org/help/robots), and I certainly didn't intend to violate the
rule against "rapid-fire requests," so it would be nice if the default
settings for Adobe Reader didn't result in an unintentional violation.

Wait Events "log file parallel write" / "log file sync" during CREATE INDEX

Hello guys,
at my current project i am performing some performance tests for oracle data guard. The question is "How does a LGWR SYNC transfer influences the system performance?"
To get some performance values, that i can compare i just built up a normal oracle database in the first step.
Now i am performing different tests like creating "large" indexes, massive parallel inserts/commits, etc. to get the bench mark.
My database is an oracle 10.2.0.4 with multiplexed redo log files on AIX.
I am creating an index on a "normal" table .. i execute "dbms_workload_repository.create_snapshot()" before and after the CREATE INDEX to get an equivalent timeframe for the AWR report.
After the index is built up (round about 9 GB) i perform an awrrpt.sql to get the AWR report.
And now take a look at these values from the AWR
                                                                   Avg
                                             %Time Total Wait    wait     Waits
Event                                 Waits -outs    Time (s)    (ms)      /txn
log file parallel write              10,019     .0         132      13      33.5
log file sync                           293     .7           4      15       1.0
......How can this be possible?
Regarding to the documentation
-> log file sync: http://download.oracle.com/docs/cd/B19306_01/server.102/b14237/waitevents003.htm#sthref3120
Wait Time: The wait time includes the writing of the log buffer and the post.-> log file parallel write: http://download.oracle.com/docs/cd/B19306_01/server.102/b14237/waitevents003.htm#sthref3104
Wait Time: Time it takes for the I/Os to complete. Even though redo records are written in parallel, the parallel write is not complete until the last I/O is on disk.This was also my understanding .. the "log file sync" wait time should be higher than the "log file parallel write" wait time, because of it includes the I/O and the response time to the user session.
I could accept it, if the values are close to each other (maybe round about 1 second in total) .. but the different between 132 seconds and 4 seconds is too noticeable.
Is the behavior of the log file sync/write different when performing a DDL like CREATE INDEX (maybe async .. like you can influence it with the initialization parameter COMMIT_WRITE??)?
Do you have any idea how these values come about?
Any thoughts/ideas are welcome.
Thanks and Regards

Thank you for Nice Idea.
In this case, How can we reduce "log file parallel write" and "log file sync" waited time?
CREATE INDEX with NOLOGGINGA NOLOGGING can help, can't it?Yes - if you create index nologging then you wouldn't be generating that 10GB of redo log, so the waits would disappear.
Two points on nologging, though:
<ul>
it's "only" an index, so you could always rebuild it in the event of media corruption, but if you had lots of indexes created nologging this might cause an unreasonable delay before the system was usable again - so you should decide on a fallback option, such as taking a new backup of the tablespace as soon as all the nologging operatons had completed.
If the database, or that tablespace, is in +"force logging"+ mode, the nologging will not work.
</ul>
Don't get too alarmed by the waits, though. My guess is that the +"log file sync"+ waits are mostly from other sessions, and since there aren't many of them the other sessions are probably not seeing a performance issue. The +"log file parallel write"+ waits are caused by your create index, but they are happeninng to lgwr in the background which is running concurrently with your session - so your session is not (directly) affected by them, so may not be seeing a performance issue.
The other sessions are seeing relatively high sync times because their log file syncs have to wait for one of the large writes that you have triggered to complete, and then the logwriter includes their (little) writes with your next (large) write.
There may be a performance impact, though, from the pure volume of I/O. Apart from the I/O to write the index you have LGWR writting (N copies) of the redo for the index and ARCH is reading and writing the completed log files caused by the index build. So the 9GB of index could easily be responsible for vastly more I/O than the initial 9GB.

Pc Suite - Sync log file

Vista Enterprise - "Non-Administrator" Account.
PC Suite v7.0.9.2
Cable Connection
N78
I currently have a "small" issue with Sync. Sync works fine (i.e. my device and Outlook synchronise) however the log file doesn't seem to generate or be viewable. (The Sync screen says something like - 7 records updated but if you click view log, the log is empty).
I've done a search on my PC and there are no .lml files anywhere so I assume this is probably a permissions issue with writing out the log file.
Does anyone know where the log file should be stored when syncing?

Just downloaded new version but still have same problem.
(There goes another 30Mb of mobile data charges ;- )
I'm fairly sure it's permissions - can anyone tell me where the files are meant to get written to?

Dynamically defined output log file in log4j

I am trying to generate an output log file dynamically using log4j. I have standard configuration XML file for log4j where I have an appender configuired. In my java code I am trying to add appender to the logger and then change an output file:
<code>
Logger logger = Logger.getLogger(ClassFSTest.class);
Appender rfa =logger.getAppender("rolling");
rfa.setFile(myFileName);
rfa.activateOprions();
</code>
However getAppender method returns NULL, but at the same time I have an Appender named "rolling" in my confuiguration. And if I use standard output mechanism like "logger.info()" the message is being written into the defined file.
thanks in advance.

Hope the following link will address the solution for your problem:

How i can access log file in servlet?

How i can access log file in servlet then display it to browser.
          Can i have peice of codes...
          Thanks in advance.!


This is not something that can be answered easily. There is quite alot of code involved....
To get started I suggest you read up on the built-in package 'DBMS_LOB' from Oracle . Most of what you need you should find there.

Servlet error: Security sensitive exception occured. , where is log files?

thank you for reading my post
i get this message , where should i look for log files ?
Servlet error: Security sensitive exception occured. Please consult application log for details.

I ran into this just myself last week.
We used to show the Exception type and a stacktrace in the browser as the default error message.
In 10.1.3.1 we've modified it so that the details of the application (ie the stack trace and exception) are output by default.
Avi indicated the correct log file to look at.
If you do want to revert to the old behaviour for development time, then you can do so by setting the attribute development="true" in the orion-web.xml file of the deployed application.
<orion-web-app .... development="true"/>

Delay in event driven log file data writing? Please help!!!

System Information
Operating System: XP
Labview: 8.2
Force sensor data acquisition via DAQPad-6070E
Actuator: Actuator via MCS-3D controller
Programming Information
Number of events: 13
Position read: Reads the position and the force sensor data every second.
Move I & Forward: Moves the actuator forward with a define step size
Two actuators are made to travel certain distance. A force sensor is attached to the system. The aim here is to acquire continuous data as per the defined time wait (1 sec). The data is logged in a text file which gives the position travelled from the actuator, the force sensor data with a time stamp.
The issues I am encountering is during writing a file.
For ex: When even is activated ( Move actuator at defined stepsize) the event are logged into the log file but the positions are updated into the log file only when the next event is activated. So it means that the positions and the force values are updated into the logfile after the consecutive event is executed. If you see the logfile ex inside the attachment the red block explains the event executed but the position are updated in the next line (event). This file is just for example.
Please help here I am going wrong!
Thanks in advanced

Dear Method M
I find it out what was going on. As you mentioned that I was writing the values before the actuators achieving the final position, so I introduced a delay between the execution of two SubVI's. It isnt a clean method but it works.
thank you very much!

Itz
