Concatenate tables with same name from different servers - CR2013

Hello,
I need some help. I need data from 2 tables with the same name on different SQL servers thru an ODBC connection. When I try to get the data by adding both to my datasource I get data from one or the other. I have considered creating a view, but not sure how to handle this. Thanks.

Hi,
Linked Servers are pretty simple and straightforward, just do a search for the procedure.
I do have an additional comment, though. Depending on what tables you're gathering, I've found noticeable differences in performance when I use a connector to a DB on Server Instance "A" linked to "B" versus Server Instance B linked to A. I haven't determined the circumstances affecting one over the other.
If I'm not happy with speed using a connector A, I try switching to B. I like to use as much SQL code as possible, but you can't get around the connector still being a factor.

Bug: showing data in tables with same name, 2 different databases

Hi,
two connections, to databases "a" & "b". Both logged into the same schema, "s".
If you select table "t" in db "a" and then select the same table in db "b", the tab is not refreshed - you have to either select a different object first, or explicitly hit refresh.
regards,
William

I can reproduce this consistently on 9.2.0.1.
You need to have connections to the same schema in two different databases and the schemas must have the same table.
1 Open connection in schema 1
2 Select the table in the Tables node
3 Select the Data tab
4 Open connection to schema 2
5 Select the table in the Tables node (without going to any other tabs or objects)
What should happen is the details of the second table should occupy the main display tab and the data tab should be refreshed to show the data of the new table.
What actually happens is the main display tab apparently switches to the table in the new connection as shown by the tooltip (table@connection_name), but the data in the data tab stays the same. Refresh doesn't seem to work, only switching to a different object and back again.
The columns tab does seem to refresh properly.

How to create directories with same name in different schemas

I have two schemas on the same database.
I am trying to create directories with same name, but different paths in both the schemas.
When i created the directories in second schema, the directory paths of the first schema are automatically changed to the second path.
Is there any solution to create directories with same name, but different path in two different schemas on the same database.
Thanks,
Sridhar.

Hi,
>>When i created the directories in second schema, the directory paths of the first schema are automatically changed to the second path.
If you have removed the REPLACE clause of your create statement, then you would see that is not possible.

Mounting multiple directories with same name on different severs to a single mount point on another server

We have a requirement where in we have multiple solaris servers and each solaris server has a directory with the same name.
The files in these directories will be different.
These same name directories on multiple severs has to be mounted to a single directory on another sever.
We are planning to use NFS, but it seems we can not mount multiple directories with same name on different severs to a single mount point using NFS, and we need to create multiple mount points.
Is there any way we can achieve this so that all the directories can be mounted to a single mount point?

You can try to mount all these mount points via NFS in one additional server and then export this new tree again via NFS to all your servers.
No sure if this works. If this works, then you will have in this case just an additional level in the tree.

Two methods with same name but different return type?

Can I have two methods with same name but different return type in Java? I used to do this in C++ (method overloading or function overloading)
Here is my code:
import java.io.*;
public class Test{
public static void main(String ar[]){
try{
//I give an invalid file name to throw IO error.
File file = new File("c:/invalid file name becasue of spaces");
FileWriter writer = new FileWriter(file ,true);
writer.write("Test");
writer.close();
} catch (IOException IOe){
     System.out.println("Failure");
//call first method - displays stack trace on screen
     showerr(NPe);
//call second method - returns stack trace as string
        String msg = showerr(NPe);
        System.out.println(msg);
} // end of main
public static void showerr(Exception e){
     StringWriter sw = new StringWriter();
     PrintWriter pw = new PrintWriter(sw);
     e.printStackTrace(pw);
     try{
     pw.close();
     sw.close();
     catch (IOException IOe){
     IOe.printStackTrace();
     String stackTrace = sw.toString();
     System.out.println("Null Ptr\n" + stackTrace );
}//end of first showerr
public static String showerr(Exception e){
     StringWriter sw = new StringWriter();
     PrintWriter pw = new PrintWriter(sw);
     e.printStackTrace(pw);
     try{
     pw.close();
     sw.close();
     catch (IOException IOe){
     IOe.printStackTrace();
     return sw.toString();
}//end of second showerr
} // end of class
[\code]

Overloading is when you have multiple methods that have the same name and the same return type but take different parameters. See example
public class Overloader {
     public String buildError(Exception e){
          java.util.Date now = new java.util.Date() ;
          java.text.DateFormat format = java.text.DateFormat.getInstance() ;
          StringBuffer buffer = new StringBuffer() ;
          buffer.append(format.format(now))
               .append( " : " )
               .append( e.getClass().getName() )
               .append( " : " )
               .append( e.getMessage() ) ;
          return buffer.toString() ;
     public String buildError(String msg){
          java.util.Date now = new java.util.Date() ;
          java.text.DateFormat format = java.text.DateFormat.getInstance() ;
          StringBuffer buffer = new StringBuffer() ;
          buffer.append(format.format(now))
               .append( " : " )
               .append( msg ) ;
          return buffer.toString() ;
     public String buildErrors(int errCount){
          java.util.Date now = new java.util.Date() ;
          java.text.DateFormat format = java.text.DateFormat.getInstance() ;
          StringBuffer buffer = new StringBuffer() ;
          buffer.append(format.format(now))
               .append( " : " )
               .append( "There have been " )
               .append( errCount )
               .append( " errors encountered.") ;
          return buffer.toString() ;
}Make sense ???

Importing files with same name but different extensions

Hope I will be clear enough.
Lets say that instead of sending a file from Lightroom to an external editor, I open it directly in Photoshop.
When I'm done, I save the edited photo using the same name but in a different file format : IMG_1333.cr2 > IMG_1333.psd or IMG_1333.tif, and selecting the same folder location.
Then, I come back into Lightroom and synchronise the folder.
Why is the knew version of the picture not showing up beside the original file, despite the different extension ?
I notice that the different extensions ( .psd or .tif ) are recorded in the sidecar files field in the Metadata panel.
Of course, everything works fine if the file name is modified ( or just by selecting the "copy" option in Photoshop's "save as" dialog box ). Lightroom synchronise dialog shows the new photo to import.
So, why is Lightroom not making a difference between files with the same name but different format extensions ?
Thanks for any hint :-)
Gilles.

Gilles-
I think your problem is likely that you have the option to stack the copy with the original turned on. First, right-click on one of these photos and go to the stacking menu. If Unstack is not grayed out then you have a stack -- select Unstack to reveal all copies.
To change the automatic stacking of edited copies from Photoshop, when you next choose to edit a file, in the bottom left corner of the dialog is the check box for unstacking. Clear it, and that choice should "stick" until you change it again.
Hope this helps!

How do I call methods with the same name from different classes

I have a user class which needs to make calls to methods with the same name but to ojects of a different type.
My User class will create an object of type MyDAO or of type RemoteDAO.
The RemoteDAO class is simply a wrapper class around a MyDAO object type to allow a MyDAO object to be accessed remotely. Note the interface MyInterface which MyDAO must implement cannot throw RemoteExceptions.
Problem is I have ended up with 2 identical User classes which only differ in the type of object they make calls to, method names and functionality are identical.
Is there any way I can get around this problem?
Thanks ... J
My classes are defined as followes
interface MyInterface{
     //Does not and CANNOT declare to throw any exceptions
    public String sayHello();
class MyDAO implements MyInterface{
   public String sayHello(){
          return ("Hello from DAO");
interface RemoteDAO extends java.rmi.Remote{
     public String sayHello() throws java.rmi.RemoteException;
class RemoteDAOImpl extends UnicastRemoteObject implements RemoteDAO{
     MyDAO dao = new MyDAO();
    public String sayHello() throws java.rmi.RemoteException{
          return dao.sayHello();
class User{
   //MyDAO dao = new MyDAO();
   //OR
   RemoteDAO dao = new RemoteDAO();
   public void callDAO(){
          try{
          System.out.println( dao.sayHello() );
          catch( Exception e ){
}

>
That's only a good idea if the semantics of sayHello
as defined in MyInterface suggest that a
RemoteException could occur. If not, then you're
designing the interface to suit the way the
implementing classes will be written, which smells.
:-)But in practice you can't make a call which can be handled either remotely or locally without, at some point, dealing with the RemoteException.
Therefore either RemoteException must be part of the interface or (an this is probably more satisfactory) you don't use the remote interface directly, but MyInterface is implemented by a wrapper class which deals with the exception.

Deploying EJBs with same name in different application jars on JBOSS

Hi,
We are attempting to deploy entity beans with the same name in 2 different EJB application jars on jboss 3.2.5. One bean is an extension of the other, so some of the DB columns they refer to are the same (they access different DB tables in different tablespaces). However, the field names corresponding to these DB columns in the beans themselves are different (i.e. DB column serviceid is associated with the field serviceid in one bean and service_id in the other).
We have altered jboss.xml for one of the EJB applications so that the jndi-name used to access that application's bean is different to the jndi-name used to access the entity bean in the other EJB jar.
However, when we attempt to deploy both jar files on the same jboss server, one of the applications deploys successfully and when we deploy the other, we get EJB spec violation errors, such as the following:
14:18:34,631 WARN [verifier] EJB spec violation:
Bean : CommunityAddress
Section: 10.6.2
Warning: The entity bean class must define a get accessor for each CMP field.
Info : Field: service_id
I'm presuming that this is because the bean which references the serviceid DB column with a field called serviceid is being mixed up with the other bean, which has a service_id field.
Can anyone tell me if there is anything else that is required to get entity beans/EJBs in different applications but with the same names (and some overlapping fields, etc) deployed successfully on the same jboss server apart from editing jboss.xml for one of the applications?
Is this a jbosscmp-jdbc.xml issue?
Any help much appreciated,
Maurice

Hi Srinath
Thanks for your response. Its not cloning, its like check-in file first, then check-out the file and do some editing and then again upload the same file with different revision number using RIDC. I got the solution now.

UPDATING A TABLE WITH SAME INFO FROM ANOTHER TABLE ON THE SAME DB

0down votefavorite
I am trying to update a table with info from another table on the same db with same table name. I just want the info to be the same , no primary key or constraint involve just a straight replacement of records and I keep getting errors WITH THE TABLE not
being recignize. below is my query:
UPDATE
VNDFIL
SET EOBTYP
= VNDFIL.EOBTYP,
EDI_X12_835_VERSION = VNDFIL.EDI_X12_835_VERSION
FROM
AGERECOVERY
WHERE
VNDFIL.EOBTYP
= VNDFIL.EOBTYP
AND
VNDFIL
.EDI_X12_835_VERSION
= VNDFIL.EDI_X12_835_VERSION

Hi rotary,
If those two same named tables are in the same database then they have to be in different schemas. If you mean they are in the same server instance, then they may be in different databases, besides the "table not being recognized" error,
anyway you should use the fully qualified table names, that is database.Schema.Table(If across instances, ServerName should be prefixed) to avoid the table unrecognized error.
Using Identifiers As Object Names
With the fully qualified names, your update statement can be like below.
UPDATE
db1.schema1.VNDFIL
SET EOBTYP = srcTbl.EOBTYP, EDI_X12_835_VERSION = srcTbl.EDI_X12_835_VERSION
FROM
db1.schema2.VNDFIL srcTbl
WHERE
db1.schema1.VNDFIL.EOBTYP = srcTbl.VNDFIL.EOBTYP AND
db1.schema1.VNDFIL.EDI_X12_835_VERSION = srcTbl.VNDFIL.EDI_X12_835_VERSION
If you have any question, feel free to let me know.

Change selected file to a file with same name but different extension.

So I'm getting better at using Automator to create useful Services but still a bit of a newbie with doing powerful things with AppleScript... and I think this task requires some applescripting. Here's what I want to do:
1. Based on a selected text file I want to run a pre-existing script that converts this file into an HTML file. This new file has the same name as the text file but has the .html extension rather than the .txt extension. (This step is easy enough and it works just fine already.)
2. BUT NOW, I want to take that resulting HTML file and run another pre-existing script that converts the HTML file into an RTF file. The problem is that I basically want to change the selection from selectedfile.TXT to selectedfile.HTML so that I can proceed to this next step...
3. AND THEN, I want to launch an app with this resulting RTF file. Again, I need to change the selection to selectedfile.RTF.
Right now this requires me to run three different services, and changing the selected file between each step... But I'm sure there's an easy applescript way (or other way) to do this using just one service -- probably involves some filename parsing and some magic to change the selection??? -- or something like that...
Could anyone point me in the right direction???
Thank you thank you thank you!
~zyyyy

You can chain your scripts together - depending on the complexity of your pre-existing scripts, you could do this with either AppleScript or Automator. The workflow would just take the selected text file (from step 1), convert to both HTML (2) and RTF (3), then launch your application with the resulting RTF - no need to change any selection.
By the way, this is the Tiger Automator forum - Snow Leopard's Automator is quite a bit different, so you will probably have better luck posting in the Snow Leopard forum.

Funny bug in SQLDev 2.1EA - tables with same name...

Hi,
i opened two session in SQLDev 2.1EA, on two distinct instances.
These sessions are open against the same user and i am clicking on a table with the same name.
This happens only when the "pin" icon is not set.
Apparently SQLDev doesn't not distinguish between the two connections when it comes to display the object attributes like columns, data, indexes and so on.
So, practically, if i click on object 1 (instance 1), click on data tab, then i click on object 1 (instance 2), i still see the data for instance 1, no matter if i ask to refresh.
This doesn't happen if i open each object in a separate tab.
This happens on SQLDev on Mac OS X.

Sorry to drop in, but I suppose many have this setup: the same users/connections on both development and production databases.
However I'm not able to reproduce now on my 10g DBs, I did see the same problem a couple of versions ago (when I was on 9i), but AFAIK that got fixed. Maybe regression anyway?

How to load the same classes of the same name, from different jars

Hi,
I have several different versions of my project in respective jars. I am trying to develop a configuration app, which will have the most current version of my app packaged within it. Then the user will make a selection, and if that selection is an older version, a specific class from one of the jars...which will continue to load other classes within that same jar. If it is the current version, the class will be found within the codebase.
My question is if this is even possible? Can I load a class from a jar file which has the same file name and package as what is in my current code?

nasch_,
So I have been searchin around, and found some good tutorials on classloaders, But i still see a problem.
Whether I use the same classloader for different sources or not, the problem lies within the reference to the class i am loading. Since this class (a different version of it), is also in the classpath, how does the code know which class is being returned?
I am having trouble putting this into words, but basically. i don't see how my application will know that i am returning an instance of a class which is not in my classpath.

Managing dbs with same names on different hosts in GC 10.2.0.3

I saw this post: Ideas needed - monitoring same DBName in manual standby
But my issue is we have an environment that keeps the same db names for production, development, uat etc... Dbs are 10.2.0.3 on Solaris 10. GC is 10.2.0.3 on windows.
e.g. i have a cluster database HRMS, running on two nodes. On another server, i have a standalone instance HRMS and Grid Control was able to detect it. Weird, it looked like it didn't care about the same name here (may be there is a difference between a database instance and a cluster instance). However, if i were to discover another target on another node, it will complain saying there is another instance. I have used the workaround to manually add it as say HRMS_hostname. All is good.
I'm curious though as to how when you create a standby database using GC, it creates a different unique name. (DB_UNIQUE_NAME). The latter seems to be the solution in having dbs with the same name in GC with different db_unique_name parameter. However, this parameter is not modifiable.
Comments anyone?
Thanks.

Try this and rediscover the database in GC and see what you get.

Using multiple SSIDs with same name but different PSKs

I have a central WLC 2504 controller that is being used for remote site FlexConnect 1141 APs. They all advertise three different SSIDs. One SSID is a global SSID that is the same at every office. One is a hidden SSID using 802.1x machine auth.
The one I am trying to get working is the local office guest network. These SSIDs are all the same at each office but should have different PSKs. They are local to the office, therefore would only ever be applied to a specific FlexConnect group.
I understand why in theory this is generally not a good idea but given these are for remote sites I'd like it to be possible. I always get this message though:
"WLAN with duplicate SSID and L2 security policy found"
Is there a way around this? New WLC code that allows it maybe?

I was able to configure three (more I think possible) WLANs with same SSID name and all are WPA2-AES-PSK on the same WLC and all are enabled at hte same time.
Note that you can not have any of those broadcasting on same AP group. Each WLAN can be only broadcasted on a separate AP group. For your sites, It will probably need you to define an AP group for each site to broadcast different WLANs on different sites.
You can do that if all your WLANs have an ID of 17 or higher. (the reason is, WLANs of 1-16 are by default broadcasted on the default AP group. and because those can not be on the same AP group - including the default one - then you can't have them with WLAN IDs 1-16. i.e on same - default - AP group)
