  I don't see a problem with these steps. It is correct. Step 7 is redundant (because of the where you have placed the tnsnames.ora file)-it is only really necessary when you place the file in another directory where +%ORACLE_HOME%\network\admin+ is no longer applicable.

  Note that the customer himself, needs to load the DLL of OIC InstantClient - and this DLL uses the settings of environment and the rest of "do its thing".

  If customer load another customer Oracle DLLS, then bets are open InstantClient is used, never mind will work.

  Only one copy of a DLL can exist in memory. So if some other s/w is using other DLL OIC, then this DLL is already loaded and will be used by all other client s/w. Nothing will be able to use the DLL itself InstantClient.

  Therefore, make sure that no Oracle client driver is loaded at all. Then make sure that when the client s/w requests to load the DLL of the OIC, it is loaded from the InstantClient directory.

  As far as I remember, the core Win32 LoadLibrary() call is made by the application - if the DLL is not in memory, the current (in the virtual machine for this process of Windows) directory is used. If the DLL does not exist there, the %PATH% variable is used to find and load the DLL. DLL usage meter is then set to 1. When multiple processes require the DLL, it is incremented. When a process ends, the usage count is decremented. When it reaches 0, its unloaded from memory.

  Result of all this is that only one module DLL (whatever the number and versions of the physical DLL files on disk) can reside in the kernel space, and you must ensure that the correct physical DLL is loaded by the kernel.

• Connect the JSK & Sql developer

  Hello

  Someone trying to connect JSK SQL Developer? I tried to do by using the credentials of DB that I could see in server.xml but without success.

  Thank you!

  Usually the HSQLDB JSK uses works in memory mode, not in Server mode - see "Server Modes" at http://hsqldb.org/doc/guide/running-chapt.html. This means that it is not possible to use a tool like SQL Developer, TOAD, squirrel etc to connect in it. You can manually write a script so that it starts the DB in Server mode, you will need to change the jdbc connection string in server.xml in an appropriate manner. Then you should be able to use an external tool to reach the DB using the same jdbc connection string.

  If you just need to make a simple few queries then you can try the query tool that comes with HSQLDB. It is very basic, but has the advantage that you need not change the DB mode, it can connect to a DB in memory of a JSK running. To run it, find the hsqldb.jar in JSK and run:

  Java - cp hsqldb.jar org.hsqldb.util.DatabaseManagerSwing

• A question about the Oracle SQL Developer Oracle instance connection

  Hi all
  
  I would be grateful if you could kindly give me a helping hand.
  
  Recently, I installed the Oracle 11 g on Linux (ubuntu 8.10) database. I not create startup scripts. So here's how I start the server: (my linux user name is "dariyoosh", but in order to start the server I have connection on the terminal shell as user 'oracle')
  

  dariyoosh@alborz:~$ su oracle
  Password: 
  oracle@alborz:/home/dariyoosh$ cd
  oracle@alborz:~$ ORACLE_SID=database01
  oracle@alborz:~$ . oraenv
  ORACLE_SID = [database01] ? 
  The Oracle base for ORACLE_HOME=/u01/app/oracle/product/11.1.0/db_1 is /u01/app/oracle
  oracle@alborz:~$ sqlplus '/as sysdba'
  ...
  SQL> STARTUP NOMOUNT
  ORACLE instance started.
  ...
  SQL> ALTER DATABASE MOUNT;
  ...
  SQL> ALTER DATABASE OPEN;
  
  Database altered.

  Then I can work without any problems with my database and everything works pretty well. Today, I decided to install Oracle SQL Developer IDE as it makes it easier to modify the SQL code. My problem is that after reading the tutorial Oracle online, that I am still able to connect to my database. Firstly according to the method that I wrote, I have set up the Oracle instance. But then when I run Oracle SQL Developer I don't know what to choose for the user name and password? because since SQL * Plus shell as you can see I always write: "sqlplus 'virtue sysdba' and it does not prompt me for any password, I can access the database directly." Any idea? What password? What user name? for Oracle SQL Developer?
  
  Thanks in advance.

  When you connect "/ as sysdba", you actually connect as the user named SYS from the privileges of your operating system. SYS is the owner of the database and a privileged user. You really want to use this username for the day to day operations, but only for what can do only SYS. If you need a different user name. Several Oracle databases have a user named SCOTT who has a number of tables for use tutorial. By default, the password for SCOTT's "Tiger." You may also have other demo users, such as "HR". I admit that I forgot what is the password of the HR, but it doesn't really matter because SYS can change with this command:

  ALTER USER hr IDENTIFIED BY whateveryouwant;
  

  This command:

  SELECT USERNAME FROM ALL_USERS;
  

  lists all the users in your database. Understand that many of these users are there as owners of objects such as stored procedures and tables for Application Express, or TYPEs for Oracle Locator, not for general use. When you are ready to create your own objects, ask SYS create a username for them with

  CREATE USER myusername IDENTIFIED BY mypassword;
  

  and grant that user the privileges as necessary. You'll want to read before you get too far - I think that the developer of the Application Guide is a good starting point.

• Failure of the assertion when using Labview ActiveX functions to communicate with the dll

  Hello

  I'm looking for suggestions and tips about the following error that I get when I use .NET Labview functions to communicate with the dll written in .NET environment. I just need a starting pointer on where can I search for the origin of this error. I am a newbie in. NET.

  

  I am also attaching the .vi I use, if this is of any help. All suggestions are welcome!  Thank you.

  The origin of the error found after studying the examples provided by the OR .NET. The callback function had to be moved out of the loop, which solved the problem.

• Using the PL - SQL CAST function

  Hi friends,

  I write a stored procedure that attempts to convert a string returned by a function in a fixed-size varchar (3).

  
  

  ex:

  newChar varchar (3);

  
  

  newChar: = cast (fn_getValue (aInputValue) as varchar (3));

  This is the return type of the function ( fn_getValue) is varchar2 (4000), I should keep the return type as varchar2 because size should vary according to the entry.

  When I run the procedure gives:

  PLS-00103: encountered the symbol "(" quand attend une deles de valeurs suivantes:) "

  . ) @ %

  Please, help me to meet my needs.

  Thanks for your reply...

  It is a generic function and the 3 I've mentioned is just an example, it can change on different cases.

  I tried with select cast (fn_getValue as varchar (aInputValue) (3)) in the double newChar; his work...

• Meaning of the column SQL Developer icon

  The icons next to some of my paintings have a white line horizontal wavvy through them (as the table is broken?). Anyone know what this means?
  
  
  Also, if I develop this tree table, some of the icons beside the columns resemble a "table cut in two." Can anyone interpret what do these symbols mean?
  
  Thank you

  And those who would be the partitions.

  Don't know why they appear because you can't select or right-click on them (in 3.0.02 anyway) and you can get the list and more info by clicking on the table and tab partition on the top right window.

• Solve the ODE which uses a max() function

  I have an ODE that I would like to solve in labview, but it's the max() for the third function OF. How can I integrate this into the Solver, RK4? I also apply it over a period of ten minutes (t here is in minutes), so I would put the RK4 Solver within some set time the end time to be 10 + loop with a start time register offset, or simply? I've included the variables + constants table for your reference.

  

  

  I do not understand your question about the error. Comments about all numerical values are already doubled.

  I found the basic problem. Column to 1 d array.vi returns an array containing a single element. This causes the Solver RK choke because it needs of 4 elements. The solution is to use only the Index table. This version converge in about 11 iterations.

  The solution seems to be sensitive to the value of h, so something's not quite yet. Fixing that may depend on your knowledge of what represent equations.

  I enclose the things that I've changed. In the f picker.vi I added the * as mentioned previously. I also reformatted some constants, although I think it was unnecessary. In the Main VI, I added a bunch of indicators so I could see what was going on. These indicators led me to the size of the array, I also added a waiting for me to see the results of each iteration. You will want to remove that in your final version.  I've implemented a "approximately equal" function to stop the loop. I put it as stop on an error.

  I consider calculate two options outside the loop and then simply select the one you want on the inside. No time to run, but if you need hundreds or thousands of iterations to solve the equations we can add.

• I need to install the Oracle client until I can use Oracle SQL Developer?

  Hi all
  
  I used to use the PL/SQL Developer to connect to the Oracle server, and before it can work, I have to install Oracle on my PC client.
  
  So I wonder to know if I use Oracle SQL Developer, what I have to do the same thing? If not, why?
  
  Thank you very much.

  Hello Serge,

  you don't need a client. Developer SQL uses JDBC to connect.

• Characters not visible (caused by hitting the bar space or TAB in PL/SQL developer tool) causing slow running query? and database with low performance?

  Hi all

  I need your help to get this issue resolved its urgent and I'm not able to get to the conclusion. Here is my scenario, I'm getting slow query runs because of some non-visible characters that are copied with the application of the PL/SQL developer tool. Please find below attached screenshot: Oracle_Issue

  

  Note: This non-visible characters are caused when we write the query then us hit the SPACEBAR or press TAB PL/SQL developer tool

  I use the developer tool PL/SQL to write or test the query. Now I take this request copy paste in my application of the company (who takes this query connects to Oracle or any source of data base, catch data and produce PDF reports for customers).

  Now, my client is the Oracle user when I write and you run this query by the PL/SQL Developer, it works fine, but when I paste in my Inbox feature request (reporting system) and run it, it runs slower and jams to the customer database. Now after a little research I found that when I copy the query directly from PL/SQL developer at my request, he copy some characters not visible (introduced when we press SPACE or TAB in PL/SQL developer tool when writing query) with the request, then I copy this query again to my box of the application Notepad and delete these non-visible characters. Now, after removing the non-visible characters again once I copy backup question in my application and run the query, it works normally. Please find below attached screenshot: Oracle_Issue 2

  

  So I think that the cause of slow performance is due to some INVISIBLE CHARACTERS present in the query.

  My application uses SQL server 2008-2012 at the backend to store data from different sources.

  Character set used: SQL_Latin1_General_CP1_CI_AS

  
  

  To write and test queries: PL/SQL developer tool

  My Client use Oracle 11 g

  Character set used: Normal character: NLS_CHARACTER: AL16UTF16

  National Characeter: NLS_NCHAR_CHARACTER: WE8WIN1521

  I just wanted to know the blocking process to the top of the database and the characters not visible how affecting slow running query of query database.

  Please let me know if I'm missing something or you need more information on this issue.

  Thanks in advance,

  HP

  Simple answer. No.

  Spaces and line breaks do not change the execution plan created. Does not plan to run slower or faster.

• SQL Developer Cart deployment wasting time on Date columns

  I tried to use the basket of SQL Developer functionality to migrate Oracle Cloud of AWS and I found that the time of all the date attributes element is not migrated. I checked the content of the deployment file and found that both the SQL * Loader control and the data file (ldr) ignore time information in an attribute table date.
  
  Anyone encountered this problem and knows how to get SQL Developer to pick up time when he pulls date attribute values?

  Hello

  There is no particular preference control the date format in the database. Public services | Basket, so the behavior has to be automatic or according to the definition of NLS.

  You might check if tools | Preferences | Database | NLS | Date format already contains an element of time format. If the cart unfurl dates does not work even with the right NLS format, then this it can be tapped. Perhaps an improvement has been made for the next version. Please let us know. I ping the developer about this.

  Kind regards
