Re: select query unable to read data

Hi Expert,
for the below code i am getting error for data mismatch i.e FOR OBJEK AND JTAB-MATNR As i am comparing objek with
matnr it is throwing length mismatch error
SELECT OBJEK
         ATINN
         FROM AUSP INTO TABLE IT_CHAR2
        move line-matnr to line-objek.
         FOR ALL ENTRIES IN JTAB
         WHERE OBJEK EQ JTAB-MATNR.
Regards,
Am

Hi
In the declaration of JTAB
data : begin of JTAB occurs 0,
              MATNR type AUSP-OBJEK " Instead of MARA-MATNR or simply MATNR You need to add it
whenever you use FOR ALL ENTRIES the field in left side in the where condition should match length wise with that of the right side one
Ex
select objek
     from AUSP
     into table itab
for all entries in JTAB
where objek = jtab-matnr " here JTAB-MATNR should have equal length of AUSP-OBJECK
which is 50 char length(if i am not wrong) where as normal MATNR is of 18 char length
Hope this serves the purpose

Error: ORA 1466
Text:   unable to read data -- object definition has changed
Cause: This is a time-based read consistency error for a database object,
        such as a table or index.
        Either of the following may have happened:
        The query was parsed and executed with a snapshot older than the time
        the object was changed.
        The creation time-stamp of the object is greater than the current
        system time.
        This happens, for example, when the system time is set to a time
        earlier than the creation time of the object.
Action: If the cause is
        an old snapshot, then commit or rollback the transaction and resume
        work.
        a creation time-stamp in the future, ensure the system time is set
        correctly.
        If the object creation time-stamp is still greater than the system
        time, then export the object's data, drop the object, recreate the
        object so it has a new creation time-stamp, import the object's data,
        and resume work.

You can not perform DDL and then perform a flashback query to before the DDL.
One might wonder why you chose this particular time to perform an ALTER TABLE but you did. It is what it is.

In oracle rac, If user query a select query and in processing data is fetched but in the duration of fetching the particular node is evicted then how failover to another node internally?

In oracle rac, If user query a select query and in processing data is fetched but in the duration of fetching the particular node is evicted then how failover to another node internally?

The query is re-issued as a flashback query and the client process can continue to fetch from the cursor. This is described in the Net Services Administrators Guide, the section on Transparent Application Failover.

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.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));

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;

char[] receivedChars = new char[client.ReceiveBufferSize];

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:

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!

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();

Unable to read data from the SAP marketplace

Hi All,
    These days, certain packages in my download basketball cannot be downloaded, while others can be downloaded normally.
     After serveral redirecting, the SAP download manager keeps informing me that "Unable to read data from the SAP marketplace, check your settings and try again".
     Anyone knows how to solve it?
Thanks,
Yining

Hi Yining,
You user on SAP MarketPlace is locked.
You have to unlock it but I do not know the way.

Unable to read data from the SAP Service Marketplace issue

Good morning, experts.
I´ve just installed the SAP Download Manager, but I can´t get connected to Marketplace.
First I tried downloading a file I could see in my Basket Download. Then I deleted it from the basket so I could test only the connection. In both situations I got the same error message: "Unable to read data from the SAP Service Marketplace (...)".
It is probably due to wrong settings, but I can´t figure it out. My settings are:
Address: https://websmp205.sap-ag.de/
User name: S0005951541
Password: (my password)
Proxy (my proxy settings)
Any ideas?

Thanks for your answer.
I can see my download basket online. I realize I didn´t delete the items so I could test purely the connection. I am going to do it again.
I found out I dind´t have permission to download those items, and with the right permission I could download them directly online.
As long as I have more information I am going to repost this issue on a new forum.
Thanks.

IMAQ Vision Unable to read data.

This project is to match multiple templates, then i copied the method from the example "Match Multiple Geometric Pattens", but the error says:
Error -1074395989 occurred at IMAQ ReadImageAndVisionInfo
Possible reason(s):
IMAQ Vision: Unable to read data.
The problem is that the programming works if I use the labview example's templates. However,when i use the templates which generated by myself, the error appears. I have checked the format and pixels of my generated template, which looks indentical to the example's template.
Could anybody help me to figure this out? I have attached my docs below.
Thanks.

Hello,
Labview Geometric matching uses a set of features/descriptors to describe the meaningful information contained in an image. You need to extract these descriptors to permorm the matching.
Here is an example on how to create the pattern matching templates in Labview (you can alternatively use the Template Editor utility):
http://forums.ni.com/t5/Machine-Vision/In-Pattern-matching-angle-remains-Zero-even-if-the-rotated/m-...
(see the attachment in the solution post). You can easily adapt this to learn geometric template (just modify/replace the relevant vi.'s).
Don't use screen shots to create the templates. Create a template directly from the image.

It searches the device successfully but but doesnt display its device details,components etc.
I checked in MI server for short dumps TSV_TNEW_PAGE_ALLOC_FAILED.
All the measures have been taken to remove this dump. But problem still persist.

Unable to read data from Analog Devices 6b11 module - error code 1240

Hi everyone,
I'm trying to read data from a thermocouple with an AD 6B11 module in an AD 6BP16-1 backplane using RS232 serial. I've been following this guide:
http://digital.ni.com/public.nsf/allkb/8C77E5E52B4A27968625611600559421
Everything seems to work out well until step 13, where I call the "AD6B Input Module - Read Data.VI". I get an error code 1240 stating something like "invalid parameter or unable to read instrument".
Has anyone got any experience with this error or suggestions to fixing it?
Thanks in advance!

That user guide is 20+ years old. The serial functions from that day used 0 for com 1, 1 for com 2, etc. Make sure you have the correct one selected. Please provide the exact error message instead of 'something like'.

when qty 9 will out the rate are 6 qty rate 458.1 and other 3 out rate of 457.2 means total value of 9 out qty value is 4120.20 .
Now 35 qty is completed and after that rate will continue with 457.2 till 10 qty not completed.
I think you understand my detail if not please tell me .
thanks

Need help in writing a select query to pull required data from 3 tables.

Hi,
I have three tables EmpIDs,EmpRoles and LatestRoles. I need to write a select Query to get roles of all employees present in EmpIDs table by referring EmpRoles and LatestRoles.
The condition is first look into table EmpRoles and if it has more than one entry for a particular Employee ID than only need to get the Role from LatestRoles other wise consider
the role from EmpRoles .
Sample Script:
Create Table #EmpIDs
(EmplID int )
Create Table #EmpRoles
(EMPID int,Designation varchar(50))
Create Table #LatestRoles
EmpID int,
Designation varchar(50)
Insert into #EmpIDs values (1),(2),(3)
Insert into #EmpRoles values (1,'Role1'),(2,'Role1'),(2,'Role2'),(3,'Role1')
Insert into #LatestRoles values (2,'Role2')
Employee ID 2 is having two roles defined in EmpRoles so for EmpID 2 need to fetch Role from LatestRoles table and for
remaining ID's need to fetch from EmpRoles .
My Final Output of select query should be like below.
EmpID Role
1 Role1
2 Role2
3 Role1
Please help.
Mohan

Mohan,
Can you check if this answers your requirement:
Create Table #EmpIDs
(EmplID int )
Create Table #EmpRoles
(EMPID int,Designation varchar(50))
Create Table #LatestRoles
EmpID int,
Designation varchar(50)
Insert into #EmpIDs values (1)
Insert into #EmpIDs values (2)
Insert into #EmpIDs values (3)
Insert into #EmpRoles values (1,'Role1')
Insert into #EmpRoles values (2,'Role2')
Insert into #EmpRoles values (2,'Role1')
Insert into #EmpRoles values (3,'Role1')
Insert into #LatestRoles values (2,'Role2')
--Method 1
select e.EmplID,MIN(ISNULL(l.Designation,r.Designation)) as Designation
from #empids e
left join #emproles r on e.emplID=r.EmpID
left join #latestRoles l on e.emplID=l.EmpID
group by e.EmplID
--Method 2
;with cte
as
select distinct e.EmplID,r.Designation,count(*) over(partition by e.emplID) cnt
from #empids e
left join #emproles r on e.emplID=r.EmpID
select emplID,Designation
from cte
where cnt=1
UNION ALL
select a.EmplID,l.Designation
from
(select distinct EmplID from cte where cnt>1) a
join #Latestroles l on a.EmplID=l.EmpID
order by emplID
Thanks,
Jay
