Read data from Archive logs

Does anyone have any recommandations on how to read data from archive logs. When i use log minor, i am getting only bind variables for DML operations. But i need actual data from the archive logs..
Any thoughts
Thanks
-Prasad

Log miner is the closest to command issued as possible. Depending on the Oracle version you will be able to see DML or DML and DDL. From 9i and on Oracle was able to translate the DML against data dictionary as the actual DDL command. On its first 8i release only DML was visible.

Read data from a log file to flex textarea while deploying

Hi,
I am new to flex. I am able to read data from a log file that placed in C drive and able to write that data into flex textarea, but I am unable to read the same file while it is deployed into weblogic sever.
Could anyone please tell me how to solve this problem.
Thanks,
Sri.

Do you have it trying to read that same file on your C drive or is the file actually deployed somewhere on the server?

Goldengate extracting from Archive log

Dear All,
We are conducting a replication of Oracle Database. Due to high load on Production server, the client is providing us a near DR database server for extraction. This database server is using Oracle Data Guard to be in Sync with Production server. Hence we will be using Archive logs shipped from Production to DR to Extract changed data. I have searched on the Net and read manuals, but I am unable to understand the how to configure OGG for this scenario. I understand that we can used Tranlogoptions parameter to extract data from Archive logs, but since the near DR database is in Mount state, how can we Log in the database using userid /password in extract process. Also we need to have Select any dictionary privileges on the database, but database is in mount state, so how to work on it??
Awaiting eagerly for the reply.l

For a physical standby, you can configure GG to read the archived standby logs in archive log only (ALO) mode.
ARCHIVEDLOGONLY causes Extract to read from the archived logs exclusively, without querying or validating the logs from system views such as v$log and v$archived_log. This parameter puts Extract into Archived Log Only mode (ALO). For more information, see the Oracle GoldenGate Oracle Installation and Setup Guide.
You can configure the Extract process to read exclusively from the archived logs. This is
known as Archived Log Only (ALO) mode. In this mode, Extract only reads from archived
logs that are stored in a specified location. ALO mode allows Oracle GoldenGate to use
production logs that are shipped over to a secondary database (such as a standby) as the
data source for Oracle GoldenGate. The online logs will not be used. Oracle GoldenGate
will connect to the secondary database to get metadata and other required data as needed.
As an alternative, ALO mode is supported on the production system.
Extract automatically operates in ALO mode if it detects that the database is a physical standby.
Lots of other info in the Oracle install guide.

How to read data from a file that is already open by another program

Hey..
I have made IV, where I'm trying to read data from a log file, that is being updated by another program while my IV runs.
To be clear, this program writes data continuously to this file and I want to read from the file in LV at the same time.
The problem is that LV reports an error when I'm trying to read the log file, even if I use to "read only" mode.
I believe that the program that is producing the file, have some kind of lock on the file. I have tryed to copy the file and then reading from the copied file, but LV throws already an error when I try to copy the file.
Has anyone tryed this, and found a solution.?
Additional info: The program that produces the file is STM Studio
Best Regards
Allan

Hi Alha,
when that file is locked by the other program you can't do anything about that - apart from quitting that other program. Probably this isn't an option to you…

TcpListener not working on Azure: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host

Hi Everybody,
i'm playing a little bit with Windows Azure and I'm blocked with a really simple issue (or maybe not).
I've created a Cloud Service containing one simple Worker Role. I've configured an EndPoint in the WorkerRole configuration, which allows Input connections via tcp on port 10100.
Here the ServiceDefinition.csdef file content:
<?xml version="1.0" encoding="utf-8"?>
<ServiceDefinition name="EmacCloudService" xmlns="http://schemas.microsoft.com/ServiceHosting/2008/10/ServiceDefinition" schemaVersion="2014-01.2.3">
<WorkerRole name="TcpListenerWorkerRole" vmsize="Small">
<Imports>
<Import moduleName="Diagnostics" />
<Import moduleName="RemoteAccess" />
<Import moduleName="RemoteForwarder" />
</Imports>
<Endpoints>
<InputEndpoint name="Endpoint1" protocol="tcp" port="10100" />
</Endpoints>
</WorkerRole>
</ServiceDefinition>
This WorkerRole is just creating a TcpListener object listening to the configured port (using the RoleEnvironment instance) and waits for an incoming connection. It receives a message and returns a hardcoded message (see code snippet below).
namespace TcpListenerWorkerRole
using System;
using System.Net;
using Microsoft.WindowsAzure.ServiceRuntime;
using System.Net.Sockets;
using System.Text;
using Roche.Emac.Infrastructure;

public class WorkerRole : RoleEntryPoint

LoggingProvider.Logger.Info("TcpListenerWorkerRole entry point called");
TcpListener listener = null;

listener = new TcpListener(RoleEnvironment.CurrentRoleInstance.InstanceEndpoints["Endpoint1"].IPEndpoint);
listener.ExclusiveAddressUse = false;
listener.Start();
LoggingProvider.Logger.Info(string.Format("TcpListener started at '{0}:{1}'", RoleEnvironment.CurrentRoleInstance.InstanceEndpoints["Endpoint1"].IPEndpoint.Address, RoleEnvironment.CurrentRoleInstance.InstanceEndpoints["Endpoint1"].IPEndpoint.Port));
catch (SocketException ex)
LoggingProvider.Logger.Exception("Unexpected exception while creating the TcpListener", ex);
return;
while (true)
Task.Run(async () =>
TcpClient client = await listener.AcceptTcpClientAsync();
LoggingProvider.Logger.Info(string.Format("Client connected. Address='{0}'", client.Client.RemoteEndPoint.ToString()));
NetworkStream networkStream = client.GetStream();
StreamReader reader = new StreamReader(networkStream);
StreamWriter writer = new StreamWriter(networkStream);
writer.AutoFlush = true;
string input = string.Empty;
while (true)
try
char[] receivedChars = new char[client.ReceiveBufferSize];
LoggingProvider.Logger.Info("Buffer size: " + client.ReceiveBufferSize);
int readedChars = reader.Read(receivedChars, 0, client.ReceiveBufferSize);
char[] validChars = new char[readedChars];

}).Wait();
public override bool OnStart()
// Set the maximum number of concurrent connections
ServicePointManager.DefaultConnectionLimit = 12;
DiagnosticMonitor.Start("Microsoft.WindowsAzure.Plugins.Diagnostics.ConnectionString");
RoleEnvironment.Changing += RoleEnvironment_Changing;
return base.OnStart();
private void RoleEnvironment_Changing(object sender, RoleEnvironmentChangingEventArgs e)
// If a configuration setting is changing
LoggingProvider.Logger.Info("RoleEnvironment is changing....");
if (e.Changes.Any(change => change is RoleEnvironmentConfigurationSettingChange))
// Set e.Cancel to true to restart this role instance
e.Cancel = true;
As you can see, nothing special is being done. I've used the RoleEnvironment.CurrentRoleInstance.InstanceEndpoints to retrieve the current IPEndpoint.
Running the Cloud Service in the Windows Azure Compute Emulator everything works fine, but when I deploy it in Azure, then I receive the following Exception:
2014-08-06 14:55:23,816 [Role Start Thread] INFO EMAC Log - TcpListenerWorkerRole entry point called

I've already tried to configure an internal port in the ServiceDefinition.csdef file, but I get the same exception there.
As you can see, the client can connect to the service (the log shows the message: Client connected with the address) but when it tries to read the bytes from the stream, it throws the exception.
For me it seems like Azure is preventing the retrieval of the message. I've tried to disable the Firewall in the VM in Azure and the same continues happening.
I'm using Windows Azure SDK 2.3
Any help will be very very welcome!
Thanks in advance!

En caso de que la respuesta te sirva, porfavor, márcala como válida

hi Javier,
I changed your code like this:
private AutoResetEvent connectionWaitHandle = new AutoResetEvent(false);
public override void Run()
TcpListener listener = null;
try
listener = new TcpListener(
RoleEnvironment.CurrentRoleInstance.InstanceEndpoints["Endpoint"].IPEndpoint);
listener.ExclusiveAddressUse = false;
listener.Start();
catch (SocketException se)
return;
while (true)
IAsyncResult result = listener.BeginAcceptTcpClient(HandleAsyncConnection, listener);
connectionWaitHandle.WaitOne();
The HandleAsync method is your "While (true)" code:
private void HandleAsyncConnection(IAsyncResult result)
TcpListener listener = (TcpListener)result.AsyncState;
TcpClient client = listener.EndAcceptTcpClient(result);
connectionWaitHandle.Set();
NetworkStream netStream = client.GetStream();
StreamReader reader = new StreamReader(netStream);
StreamWriter writer = new StreamWriter(netStream);
writer.AutoFlush = true;
string input = string.Empty;
try
char[] receivedChars = new char[client.ReceiveBufferSize];
// LoggingProvider.Logger.Info("Buffer size: " + client.ReceiveBufferSize);
int readedChars = reader.Read(receivedChars, 0, client.ReceiveBufferSize);
char[] validChars = new char[readedChars];
Array.ConstrainedCopy(receivedChars, 0, validChars, 0, readedChars);
input = new string(validChars);
// LoggingProvider.Logger.Info("This is what the host sent to you: " + input + ". Readed chars=" + readedChars);
try
string orderResultFormat = Encoding.ASCII.GetString(Encoding.ASCII.GetBytes("\xB")) + @"MSH|^~\&|Instrument|Laboratory|LIS|LIS Facility|20120427123212+0100||ORL^O34^ORL_O34| 11|P|2.5.1||||||UNICODE UTF-8|||LAB-28^IHE" + Environment.NewLine + "MSA|AA|10" + Environment.NewLine + @"PID|||patientId||""""||19700101|M" + Environment.NewLine + "SPM|1|sampleId&ROCHE||ORH^^HL70487|||||||P^^HL70369" + Environment.NewLine + "SAC|||sampleId" + Environment.NewLine + "ORC|OK|orderId|||SC||||20120427123212" + Encoding.ASCII.GetString(Encoding.ASCII.GetBytes("\x1c\x0d"));
writer.Write(orderResultFormat);
catch (Exception e)
// LoggingProvider.Logger.Exception("Unexpected exception while writting the response", e);
client.Close();
catch (Exception ex)
//LoggingProvider.Logger.Exception("Unexpected exception while Reading the request", ex);
client.Close();
Please try it. For this error message, I suggest you could refer to this thread (http://stackoverflow.com/questions/6173763/using-windows-azure-to-use-as-a-tcp-server

How to read data from a router by using labview

Does the router behave like a webserver that you log into? If so, search the forums for threads discussing HTML.

Read data from E$ table and insert into staging table

Hi all,
I am a new to ODI. I want your help in understanding how to read data from an "E$" table and insert into a staging table.
Scenario:
Two columns in a flat file, employee id and employee name, needs to be loaded into a datastore EMP+. A check constraint is added to allow data with employee names in upper case only to be loaded into the datastore. Check control is set to flow and static. Right click on the datastore, select control and then check. The rows that have violated the check constraint are kept in E$_EMP+ table.
Problem:
Issue is that I want to read the data from the E$_EMP+ table and transform the employee name into uppercase and move the corrected data from E$_EMP+ into EMP+. Please advise me on how to automatically handle "soft" exceptions in ODI.
Thank you

Hi Himanshu,
I have tried the approach you suggested already. That works. However, the scenario I described was very basic. Based on the error logged into the E$_EMP table, I will have to design the interface to apply more business logic before the data is actually merged into the target table.
Before the business logic is applied, I need to read each row from the E$EMP table first and I do not know how to read from E$EMP table.

Problem while reading data from USB with JSR80

Hi
Iam using Fedora 9 with 32 bit.
Iam using JSR80 api to read the data from USB devices.
I successfully set-up the code as per given on JSR80 site on my eclipsce ide.
below is my code which iam using to read data from usb
import com.ibm.jusb.*;
import java.util.List;
import javax.usb.*;
import java.util.List;
public class USBReader {

         UsbServices services = UsbHostManager.getUsbServices();
         UsbHub rootHub = services.getRootUsbHub();
         traverse(rootHub);
         testIO(rootHub);
        } catch (Exception e) {

                for (int j=0; j<totalEndpoints.size(); j++){
                   // Access the particular endpoint, determine the direction
                   // of its data flow, and type of data transfer, and open the
                   // data pipe for I/O.
                   UsbEndpoint ep = (UsbEndpoint) totalEndpoints.get(i);
                   int direction = ep.getDirection();
                   int type = ep.getType();
                   UsbPipe pipe = ep.getUsbPipe();
                   pipe.open();
                   // Perform I/O through the USB pipe here.
                   pipe.close();
                interf.release();
          } catch (Exception e) {
               System.out.println("Exception in TestIO"+e.getMessage());
               e.printStackTrace();
}When i execute the above code i get the following exception
Exception in TestIOCannot claim an interface on a virtual root hub.

Cannot claim an interface on a virtual root hubSo don't do that? I have no idea how to tell, but clearly you need to test a few more attributes before you claim. Or else just log the claim error and continue with the next interface.

EDGE SIMULATOR CAN'T READ DATA FROM SIMULATION.XML

HI,
i have installed the SES(10.1.3) and before that Application server 10.1.3 .
I have followed all the steps given at the following link
http://www.oracle.com/technology/obe/1013/fusion_middleware/integration/ses/configuringsimulator/configuresimulator.htm#t1
It works works well till step 16 and edge is restarted successfully , I exit from enterprise manager by logging out and then logging in again for edge
and then when i click on monitor events then it gives me nothing in the row( no data, no time , no id) just blank row...
Mean it does not read data from Simulation.xml file
my file (Simulation.xml) is residing in F:\oracleAS\10.1.3.1\OracleAS_1\j2ee\home\applications\edge\edge\config folder where 'edgerserver.xml' is residing.
edgeserver.xml contains all driver details i guess.
Can anyone help me to cope with the problem.
thanks :-)

Atlast i have overcome my problem , in order to read data from simulatin.xml file one has to change the "log level" in general settings to monitor and it will work .
other options for log level are , error , warning, notify and debug etc .
so change it to log level , then login as enterprise manager, restart edge , log out from emanagaer and again login to edge and click on monitor tab , u r done :-)

Best way to control and read data from multiple instruments?

Hello,
I'm building an application to test power supplies involving multiple pieces of equipment over a couple of different comm busses. The application will also send control instructions to some of the instruments, and read data from some of the instruments. The reading and control profiles will not run on the same schedule (variable length control steps, configurable read interval).
I was thinking of using a queued statemachine (producer/consumer) for the control profile and another to read the data, but I got concerned that there would be collisions between sending control commands and read commands to the same machine. Is there a suggested design pattern for implementing something like this?
Timing of the commands isn't critical down to the milisecond, but I need to collect reasonably accurate timestamps when the data is read. The same is true for the control commands.
Here are the instruments I'm going to use, if the are control, read, or both, and the communication method
Instrument Funtions Comm Method
Power Supply Read data Communicates to PMBus Adapter
PMBus to USB Adapter Read data USB (Non-Visa)
Switch control relays USB (VISA)
Power Dist. Unit read data/control outlets SNMP (Ethernet)
Electronic Load read data/control load GPIB (VISA)
Thermal Chamber read data/control temp Ethernet (VISA)
Thanks,
Simon

Hello, there is a template in LV called "Continuous measurement and Logging".
It can give you some idea how to properly decouple the "GUI Event handler" top loop (where your Event structure is) from the DAQ and other loops.
You do not need to totally replicate the above example, but you can find there nice tricks which can help you at certain points.
The second loop from the top is the "UI message loop". It handles the commands coming from the top loop, and regarding to the local state machine and other possible conditions and states, it can command the other loops below.
During normal run, the different instrument loops just do the data reading, but if you send a control command from the top loop to a certain instrument loop (use a separate Queue for every instrument loops), that loop will Dequeue the control command, execute it, and goes back to data reading mode (in data reading mode the loop Dequeu itself with a "data read" command automatically). In this way the control and data read modes happen in serial not in parallel which you want to avoid (but I think some instrument drivers can even handle parallel access, it will not happen in really parallel...).
In every instrument loop when you read a value, attach a TimeStamp to it, and send this timestamp/value couple to the DataLogging loop via a Queue. You can use a cluster including 3 items: Source(instrument)/timestamp/value. All the instrument loops can use the same "Data logging" Queue. In the Datalogging while loop, after Dequeue-ing, you can Unbundle the cluster and save the timestamp and data-value into the required channel (different channel for every instrument) of a TDMS file.
(Important: NEVER use 2 Event structures in the same top level "main" VI!)

HTTP-500 Error Reading Data from Client!!

I'm trying to create a page where by clients are able to contact us through the portal. So, it's a pretty basic form where I have a text box for the subject, and a text area for the message body.
My problem is when the message body is over a certain size, I'm getting a "portlet cannot be contacted" on my screen. The Apache log comes up with the error:
[error] mod_plsql: /pls/portal/!PORTAL.wwpob_page.show HTTP-500 Error Reading Data from Client!!
I'm not using a windows OS, so the bug that has been talked about previously talked about shouldn't be the problem.
Also, I am using a POST rather than a GET, so I don't think it has to do with the browser (and I have tested this on Firefox and IE 5.5 and IE 6).
Would appreciate any advise.
Thanks, Nicky

Are you using SSL? Maybe, it has to do with it. I encountered a similar problem. It turned up that this read error occurred inside Apache and was caused by a nonstandard-SSL-request by Internet Explorer. te remedy was to add this to the Apache configuration:
SetEnvIf User-Agent ".*MSIE.*" \
nokeepalive ssl-unclean-shutdown downgrade-1.0 force-response-1.0
It tells Apache to switch to HTTP/1.0 and to never keep open socket connections with MSIE on SSL connections.
Lycka till!

Attempt to read data from the server failed...

I'm getting the following error on one of my email accounts:
+There may be a problem with the mail server or network. Verify the settings for account “[my account]” or try again.+
+The server returned the error: The attempt to read data from the server “[my account]” failed.+
I'd like to find out more about the error, so that I can start to track this down and see if there is a problem with the mail server settings, or if the problem is on my end.
I don't see any reference to this error in the logs – would it be somewhere else?

I've just solved a similar issue.
I have a dedicated server running Plesk 9.5 and when I upgraded to iLife 11 and Snow Leopard this error appeared. I could quickly click "get mail" and I'd get all my mail, but only 3-4 of my 9 mail accounts would connect. Theo others would have the error:
The server error encountered was: The attempt to read data from the server...
I found solutions for those using IMAP mail:
modify the /etc/courier-imap/imapd configuration file and change MAXDAEMONS from 40 to 80 and MAXPERIP from 4 to 40. This allows all the machines behind my home firewall to connect to multiple accounts on the e-mail server with mailbox caching enabled.
I'd made this change on my server but it didn't seem to have any effect. It dawned on me that I'm using POP, no IMAP. So I found in /etc/courier-imap/pop3d the same settings. I changed the MAXDAEMONS from 40 to 80 and MAXPERIP from 4 to 40 and voila, all my connections concurrently worked.
This has taken me more than two days to fix and I hope posting this helps someone else with the same issue.

Error reading data from the MS Dos Console.

Hi,
We have a legacy application which is launched via a 3rd-party Telnet Server - the app acts as a remote shell for an RF device. The system has been functioning for many years but now we have migrated to Server 2012 the system no longer launches.
The RF device successfully connects to the telnet server, logs-in with embedded credentails but drops the connection when the shell application is launched.
The server has the following Application error
Error reading data from the MS Dos Console.
The pipe has been ended. 109 (0x6d)
The application can successfully be launched locally outside of the shell on the server. The error is reproducable across RF devices and desktop telnet connections.
The firewalls are off.
Are there some additional protections in Server 2012 which would cause the pipe-based link to be stopped when launching the exe? Am I missing something? The 3rd-party telnet server is certified for Server 2012.
Thnak you

I'd ask in the
Windows Server General Forum, or ask the third party vendor.

Reading data from mlx90129 rfid tag chip by using spi communication with labview?

Hi,
i have evb90129 evalution board in that mlx90129 chip and external memory (cat25128) and three external sensors are there, i am logging data from chip by using rfid reader it ok i am reading. at the same time i configured spi communication and i am trying to read data i am reading data from internal memory not from external memory i tried but i didnt suceed , now can i use labview to read data from mlx chip and external memory. for spi communication i am using sparkfunction atmega168 microcontroller and also i have spi to usb cable? now can i communicate or i required any devies? is it possible?
thanks in advance,
biji.

I suspect the culprit to be the first parameter to your function actually. Calling another function requires the caller to allocate any buffer with a big enough size for the function to write something into. Allocate that array by using Initialize Array with U8 as type and the correct number as size. Pass this size also as read_length. While your code doesn't make use of this I think the third parameter to your function is either wrong or unnecessary.
As you use it now it is really nothing more than a local stack variable which you could declare inside the fucntion just as well. On the other hand what you probably want to do is have a function prototype like:
extern "C" _declspec(dllexport) unsigned char read_Sensor(unsigned *char read_data, unsigned long read_length, unsigned long *byte_transfered);
But you will have to do some modifications in your C code to support that parameter correctly.
That all said, doing the same in LabVIEW using VISA functions would have been done with about two VISA nodes, no DLL headaches and probably already long ago working.
