Help using Oracle Diagnostic Logging (LoggingContext)

Hi,
We are developing a new Product from scratch and have decided to use as much as we can from Oracle Libraries. Currently we are using Oracle Diagnostic Logging (ODL) for logging in our application, having a wrapper on top of it, which will make our product as well in-line with other oracle product logging.
We have requirements to log based on LoggingContext as in Log4j's Mapped/Nested Diagnostic Context. I believe we can do the same using oracle.core.ojdl.logging.context.LoggingContext but can't find more information on how to use it.
Can anybody provide examples or links to learn, understand and implement using LoggingContext in ODL?

ODL generates log files in XML format only. Using ODL you can not have plain text format log files. You have to decide what is more desired - log rotation (that ODL provides) or text format (which is the default, non-ODL, format). If text format is more desired than don't enable ODL and write your own shell script to rotate application log (but that can only be done while OC4J is down).
At the same time if you are concern about readability of log file (i.e. text format is easier to read vs. xml format) than you might consider using one the log viewer tool (log viewer in EM or printlogs command line) provided by Oracle. Both of these tools help you view the logs in much more readable format than just looking at xml format log file.
(printlogs utility is under $OH/diagnostic/bin directory. Run "printlogs -help" to read about it).
Hope this helps.
Thanks

Can I generate .txt / .log file from Oracle Diagnostic Logging?

Hi all,
on my application I need to limit the size of application log, I've read this [http://download.oracle.com/docs/cd/B25221_04/web.1013/b14432/logadmin.htm#CHDJHHHB|http://download.oracle.com/docs/cd/B25221_04/web.1013/b14432/logadmin.htm#CHDJHHHB] that using ODL, but generated file is .xml, but I need .log / .txt file. How can I do this??
thanks in advance.

Help Using Oracle (In General)

I am new to Linux and Oracle, so please bear with me.
I finally was able to install Oracle 11g on my CentOS computer. (This took a long time...I'm a slow learner).
Now I'm trying to create an database or just trying to USE Oracle. Where and how do I create an new database?
I searched around this forum and saw that you should use the command "dbca" to create a database.
If this is true, I have several questions:
1. Where do I type this command (on root or on oracle user)?
2. Do I need to be in a specific directory?
3. How exactly do I use the command "dbca"?
I appreciate any help I can get. But please I need step by step solutions; providing me with a link to an Oracle documentation guide hasn't helped me.
http://download.oracle.com/docs/cd/B19306_01/server.102/b14231/create.htm#g1034097 <--This guide is very confusing and not clear in it's directions.
Or maybe, does anyone know of an Oracle Tutorial for Dummies? This would help too. ;-)
Thanks again.
Note: Remember, I am new to Linux AND Oracle. Thank you!

Reading installation documentation and following it always makes things work better.
1. The docs are at http://tahiti.oracle.com
2. Use a supported operating system (free) such as Oracle Enterprise Linux (download at http://otn.oracle.com)
3. If you find you are confused by some aspects of the docs there are many of us that have posted examples on the web.
Mine are at http://morganslibrary.org/library.html under "Linux" with different demos for the most recent 3 versions.

Help using oracle syntax "SUM(col1) over (order by col2)" using ODI

Hi all
I want to load data from oracle to ESSBASE using ODI, and I know oracle have such syntax sum(col1) over (order by col2,col3) which can get the accumulation data, e.g
Oracle data table
col1, col2, value
A 2009-1 10
A 2009-2 10
A 2009-3 10
And the essbase need
col1 col2 value
A 2009-1 10
A 2009-2 20
A 2009-3 30
However after i try this in ODI, error occur:

I know ODI think sum.. over must append group by , however it's not! How to solve this problem.
Thank All for your attention
SOS!
Ethan

Hi Ethan,
In my exeprnc I faced a similar kind of situation.
Two work arounds.
1. Write one procedure and execute the same using ODI procedure.
2. Customize a Km and use that KM in your interface.
I guess in your query Group by function is not needed. (if this is the case you can achive this by a smple customization step in KM)
for example : your current KM will generate a query like this:-
select x,y, sum(x) over (order by y) as sumx FROM TestTable group by x, y
and you need a query like this
select x,y, sum(x) over (order by y) as sumx FROM TestTable
go to your KM (duplicate the KM which you are using and rename _withoutGroup )
remove the group by function from select query
(remove the API function <%=snpRef.getGrpBy()%> from insert into i$ table step)
please let me know if you need more help on this
regards,
Rathish

Help needed in using oracle rules SDK

Hi,
For testing my rulesets using oracle rules SDK I doing the following:
1. Creation of dictionary, ruleSet.
2. Declared two kinds of globalVariable variables in my datamodel :
Final and non-Final.(Type of these varaibles are String and Double only)
3. Final globalVaraibles are used in creating rule's patterns.
4. Non-Final globalVariables are used in creating rule's action.
5. Functions are created for asserting globalVariables values and
returning non-final varaibles, since those are required as action
results.
6. In java code I am testing my ruleset (dict.testRuleSet()). Before
testing i am populating my final global variables (since these are used
in rule's patterns),
and updating datamodel.
The above procedure is working fine and I rules are successfully working.
Now, first of all i want to know if the above mentioned approach is correct or it needs to be reframed??
secondly, when i update datamodel with values (in java code itself) it
takes 4-5 seconds in updating it. This is the main issue that why it is
taking this much time??
any comment would be of great help.
Thanks in advance.

I will send up an alert for you, Colin. Even though I use iTunes for Mac, troubleshooting it isn't my forté.

Looking for some help with using Oracle stored procedures in vb2010

First off thank you to whoever lends me a hand with my problem. A little background first I am in a software development class and we are currently building our program using VB (I have no experience in this), and Oracle(currently in a Oracle class so I know how to use Oracle itself just not with VB).
I am using vb2010 express edition if that helps. Currently I have a stored procedure that takes a 4char "ID" that returns a position (ie, salesperson,manager ect). I want to use the position returned to determine what vb form is displayed (this is acting as a login as you dont want a salesperson accessing the accountants page for payroll ect).
Here is the code I have currently on the login page of my VB form
Imports Oracle.DataAccess.Client
Imports Oracle.DataAccess.Types
Public Class Login
Dim conn As New OracleConnection
Private Sub empID_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles empID.Click
End Sub
Private Sub LoginBtn_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles LoginBtn.Click
conn.ConnectionString = "User ID = Auto" & _
";Password = ********" & _
";Data Source = XE"
conn.Open()
Dim sq1 As String = "Return_Position" 'name of procedure
Dim cmd As New OracleCommand(sq1, conn)
cmd.CommandType = CommandType.StoredProcedure
cmd.Parameters.Add(New OracleParameter("I_EmpID", OracleDbType.Char, 4)).Value = Emp_ID.Text
Dim dataReader As OracleDataReader = cmd.ExecuteReader
dataReader.Read()
Dim position As New ListBox
position.Items.Add(dataReader.GetString(0)) 'were I am getting an error, I also tried using the dataReader.getstring(0) to store its value in a string but its a no go
If position.FindStringExact("MANAGER") = "MANAGER" Then
Me.Hide()
Dim CallMenu As New Menu()
CallMenu.ShowDialog()
End If
LoginBtn.Enabled = False
End Sub
I have read the oracle.net developer guide for using oracle in vb2010 and have successfully gotten through the document however they never use a stored procedure, since the teacher wants this program to user a layered architecture I cannot directly store sql queries like the document does, thus the reason I want to use stored procedures.
This is getting frustrating getting stuck with this having no background in VB, I could easily do this in c++ using file i/o even through it would be a pain in the rear....

Hello,
I am calling Oracle 11g stored procedures from VB.Net 2010. Here is a code sample (based on your code) you should be able to successfully implement in your application.
Please note that you may have to modify your stored procedure to include an OUT parameter (the employee position) if it doesn't have it yet.
Private Sub LoginBtn_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles LoginBtn.Click
Dim sProcedureName As String = "Return_Position" 'name of stored procedure
Dim ORConn as OracleConnection, sConn as String
Dim sPosition as String, sDataSource as String, sSchema as String, sPWD as String
Dim cmd As OracleCommand
'please provide below sDataSource, sSchema and sPWD in order to connect to your Oracle DB
sConn = "Data Source=" & sDataSource & ";User Id=" & sSchema & ";Password=" & sPWD & ";"
ORConn = New OracleConnection(sConn)
ORConn.Open()
cmd = New OracleCommand(sProcedureName, ORConn)
With cmd
.CommandType = Data.CommandType.StoredProcedure
'input parameter in your stored procedure is EmpId
.Parameters.Add("EmpID", OracleDbType.Varchar2).Value = Emp_ID.Text
.Parameters.Item("EmpID").Direction = ParameterDirection.Input
'output parameter in your stored procedure is Emp_Position
.Parameters.Add("Emp_Position", OracleDbType.Varchar2).Direction = ParameterDirection.Output
.Parameters.Item("Emp_Position").Size = 50 'max number of characters for employee position
Try
.ExecuteNonQuery()
Catch ex As Exception
MsgBox(ex.Message)
Exit sub
End Try
End With
sPosition = cmd.Parameters.Item("Emp_Position").Value.ToString
'close Oracle command
If Not Cmd Is Nothing Then Cmd.Dispose()
Cmd = Nothing
'close Oracle connection
If Not ORConn Is Nothing Then
If not ORConn.State = 0 Then
ORConn.Close()
End If
ORConn.Dispose()
End If
ORConn = Nothing
If UCase(sPosition) = "MANAGER" Then
Me.Hide()
Dim CallMenu As New Menu()
CallMenu.ShowDialog()
End If
LoginBtn.Enabled = False
End Sub
If you need further assistance with the code, please let me know.

How to use oracle thin driver?...pls help

Hello. I am trying to insert a word file into my Oracle 9i database using JSP. I have tomcat running as my standalone server. So far, i have been using the sun.jdbc.odbc driver to implement all my DB accesses. Recently however, i found out that in order to use Oracle specific objects such as BLOBS or BFILES, i have to use the oracle thin driver or OCI driver.
So far, i have downloaded the thin driver and put it into the tomcat shared/common folder and also put the .jar file into my classpath. Now, i am having trouble as to how to call the oracle thin driver inside my JSP code.
My previous code read as:
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection con = DriverManager.getConnection("jdbc:odbc:Andy","user","pass");
How do i switch over to the oracle thin driver in JSP? Any help would be much appreciated. Thank you
Andrew

Class.forName ("oracle.jdbc.driver.OracleDriver");
Connection conn = DriverManager.getConnection ("jdbc:oracle:thin:@hostname:port:SSID", "user", "password");

Using Oracle 11g How to change the Log mode from NoArchieve to Archieve Log

Hi,
I currently using oracle 11g How can I change database from NoArchivelog node to Archivelog node using spfile.
And where exactly the spfile will be located?
My instance is EPM11 in my local oracle is present in D folder where can i found the pfile?
In this path i found 1 pfile in my Local Machine
"D:/Oracle/Product/11g/admin/epm11/pfile" .I have added the following commands in this pfile
# Archive Log Destinations -benr(10/15/04)
log_archive_dest_1='location=/u02/oradata/cuddle/archive'
log_archive_start=TRUE
Then i have ran the shutdown command.
Database instance is showtdown.
After that i am not able to perform startup.
So please suggest me how to change the mode using SPfile and tell me the path where spfile and pfile should be located?
And also do i need to set the "Oracle_Home" path in my environment variables"
Thanks In Advance,
Chandana

Very challenging and doubtful at the same time !
I don't think, its going to be a straight-forward one... Read about OAuth twitter authentication, before you try to post tweets.

Helpful Tip on Using Debugger BreakPoint Logs

I've started using the xCode BreakPoint Logging and other BreakPoint features. Unfortunately, it became difficult to align the consule messages with the locations in the code.
I resolved the issue by setting the xCode preference for 'show line numbers' combined with getting into the habit of entering the line number at the beginning of the log statement.

The introduction I read to the use of BreakPoints was called an 'intermediate' tutorial. I don't think that's the right word.
There appears to be two distinct learning and/or creative approaches. One, which I would call 'British', invests heavily in pre-planning and thought, and therefore treats the actual appearance of changes with an almost holy reverance.
The other style, which I would say is more American, is to free-up the creative process by treating the appearance of changes and ability to change with an almost brutal disregard for what has been done in the past, even with respect to one's own work.
Neither style would be hurt, and both would benefit, from the addition of an optional 'lock' preventing the deletion of the PointBreaks when code is moved as well as an optional 'auto line number' placed into the PointBreak log text box ahead of the cursor.
But for now, thank you for the NSLog function, which will be a great help when put into the PointBreak command line along with the log text option. And I am definitely keeping a 'test' project available where I strictly use typed-in log statements for more robust exploratory learning and creativity.

Revelation: Why my diagnostic logging was not working using log4net TraceAppender

I thought I better share with people some information that I found which has shed some light on why I've had such a hard time getting native Azure diagnostic logging working. Hopefully, if I hit enough key words here, someone will find this discussion
in the future and may save you some time and heart ache.
Our application is a legacy ASP.Net application which I am porting to Azure. The application makes extensive use of log4net and I decided that I would use the log4net TraceAppender to forward the logs to the Azure diagnostic listener. Within
my worker role, I was configuring my azure logs like so:
private static void ConfigureLogging() {
CrashDumps.EnableCollection(true);
var diagConfig = DiagnosticMonitor.GetDefaultInitialConfiguration();
var directories = diagConfig.Directories;
var infrastructureDiagnostics = diagConfig.DiagnosticInfrastructureLogs;
var applicationLogs = diagConfig.Logs;
var eventLogs = diagConfig.WindowsEventLog;
SetTransferPeriod(applicationLogs, 1);
SetTransferPeriod(directories, 1);
SetTransferPeriod(infrastructureDiagnostics, 1);
SetTransferPeriod(eventLogs, 1);
SetFilterLevel(applicationLogs, LogLevel.Information);
SetFilterLevel(eventLogs, LogLevel.Information);
SetFilterLevel(infrastructureDiagnostics, LogLevel.Warning);
DiagnosticMonitor.Start("DiagnosticsConnectionString", diagConfig);
Log4NetHelper.ConfigureLog4Net();
private static void SetFilterLevel(WindowsEventLogsBufferConfiguration eventLogs, LogLevel logLevel)
eventLogs.DataSources.Add( "Application!*" );
eventLogs.DataSources.Add( "System!*" );
eventLogs.ScheduledTransferLogLevelFilter = logLevel;
private static void SetFilterLevel(BasicLogsBufferConfiguration infrastructureDiagnostics, LogLevel logLevel)
infrastructureDiagnostics.ScheduledTransferLogLevelFilter = logLevel;
private static void SetTransferPeriod(DiagnosticDataBufferConfiguration directories, int minutes)
var period = TimeSpan.FromMinutes(minutes);
directories.ScheduledTransferPeriod = period;
Log4NetHelper.Configure uses the log4net programattic API to setup and configure a TraceAppender that captured all LogLevels (DEBUG or higher). I also made sure that the follwing appeared in my Web.Config
<system.diagnostics>
<trace autoflush="false" indentsize="4">
<listeners>
<clear />
<add type="Microsoft.WindowsAzure.Diagnostics.DiagnosticMonitorTraceListener, Microsoft.WindowsAzure.Diagnostics, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" name="AzureDiagnostics">
<filter type="" />
</add>
</listeners>
</trace>
</system.diagnostics>
However, this never worked. I saw a number of forum posts that suggested that the Azure filter level should be "Undefined" - namely that I should replace
SetFilterLevel(applicationLogs, LogLevel.Information);
with
SetFilterLevel(applicationLogs, LogLevel.Undefined);
I had set my filter level to Information, cos our app does so much Debug level logging, that I thought I'd save money in storage by really only capturing the INFO or higher messages. But in the interest of getting the blasted thing to work, I set to
Undefined, and sure enough all the log message from all levels came through. Setting back to Information and NO messages come though.
I then noticed that when my logging was working (filter = Undefined) that ALL my log messages were in fact being logged at the Verbose level - even log4net calls to log.Error/log.Warn (exceptions messages being logged at Verbose is not a good sign!)
You have to realize, that my thought process was not structured at this point as I had no idea what was going on. Until I found this article:
http://www.dotnetsolutions.co.uk/blog/archive/2010/02/22/windows-azure-diagnostics-%E2%80%93-why-the-trace-writeline-method-only-sends-verbose-messages/
While not related to log4net, it was an eye opener, and I used reflector to look at the TraceAppender, and I see they are using Trace.Write to write messages.
In my mind, this explains why I was seeing the behaviour I was seeing: AzureDiagnostic listener is converting all Trace.Write messags to Verbose (details in the above article) and log4net TraceAppender is converting all log messages to Trace.Write
messages. Setting the filter to Information was thus stripping all the calls.
My solution is to inherit TraceAppender and change their impl of Append to use a switch on the LogLevel:
using System.Diagnostics;
using log4net.Appender;
using log4net.Core;
namespace XXX.Azure
public class AzureTraceAppender : TraceAppender
protected override void Append(LoggingEvent loggingEvent)
var level = loggingEvent.Level;
var message = RenderLoggingEvent(loggingEvent);
if (level >= Level.Error)
Trace.TraceError(message);
else if (level >= Level.Warn)
Trace.TraceWarning(message);
else if (level >= Level.Info)
Trace.TraceInformation(message);
else
Trace.Write(message);
if (ImmediateFlush)
Trace.Flush();
With log4net configured to use this appender, then log messages appearing in the WADLogsTable are all appearing at the correct (or nearest appropriate) level
YMMV
Pete

Thanks, that's extremely useful!
Using your appender, Verbose level messages still were not shown though. What did the trick was changing
Trace.Write(message);
to
Trace.WriteLine(message);
