• To connect to an Oracle database using oracle.jdbc.OracleDriver: error

  Hello

  I am trying to connect to an Oracle database so that we can extract information on tables, views, and packages.

  Using the Data Modeler (transformation script) API, we will add these notes to the corresponding objects in the Data Modeler.

  I'll start with this:

  importPackage (java.lang);

  importPackage (java.awt);

  importPackage (java.sql);

  java.lang.Class.forName ("oracle.jdbc.OracleDriver");

  An error occurs when I run this code:

  

  It must be something of Java...

  Someone at - it a suggestion?

  Problem solved! A colleague of mine referred to in this post: import def properties from Oracle Designer

  More in detail: it's this couple of lines:

  Copy the file ojdbc6.jar for... Directory of \datamodeler-home\jlib

  Add this line to datamodeler.conf

  AddJavaLibFile... /... /jlib/ojdbc6.jar

  I changed my file datamodeler.conf, DM rebooted and now is no longer an error when I try to use the Oracle JDBC drive.

• What do I need install Oracle Database 11 g 2 for the Oracle 10 g database migration?

  Hi all

  Would you be kind enough to help me with the following question!  I currently have Oracle Database 10 g on the old servers to my work and I want to install the GR 11, 2 on Windows Server 2008 R2 Enterprise Oracle database to new servers for upgrade.  I also forms, reports and Designer 10 g to maintain our existing applications.  So, I already looked in the Certification and found the following:

  Latest version of the product: latest version of the database server window weblogic

  Form Builder 11.1.2.0.0 11.2.0.4.0 7, 2008 R2, 2008 10.3.6.0.0

  Reports           11.1.2.0.0                                           11.2.0.4.0                                                 7, 2008 R2, 2008                                   10.3.6.0.0

  Designer 10.1.2.6.0 11.2.0.1.0 xp, vista, 7, 2003 (all 32 bit)

  For Designer, it is approved for a 32 - bit window, so I'm having trouble with the new requirement of system this window must be after 2003.  I want to take all of the availability and follow the Oracle certification (except that I will be given Designer because of compliance) as above.  I'm new with Oracle, and I don't know what comes with what to do it is complete.

  1. I'm going to install a database server (free 11.2.0.4.0 as described above) in a new server (2008 R2), then what I have to install the WebLogic Server with it?

  2. I'll install the generator of reports and Forms Builder (11.1.2.0.0) in another server (2008R2), so what I have to install WebLogic Server as well with her?

  3. what else do I need to install on this two server so that they work so that I can begin to migrate all existing data, forms and States more?

  Any advice would be greatly appreciated.  Thank you.

  Remember that this forum is targeted to the Oracle Forms product, for questions about the database can be better answered in one of the areas of database.  That being said, here are my comments:

  1 I'll install a database server (version 11.2.0.4.0 as described above) in a new server (2008 R2), then what I have to install the WebLogic Server with it?

  A database facility didn't need of WLS (which I am aware). Consider what you want is a typical design at three levels. Database - average level (applications server) - Client (tools and end user).   Each level has nothing to do with the other installation point of view assuming that they are not installed on the same computer. WLS is a middleware software (medium level). Be sure to check the product documentation before performing any installation. The 11.2 DB docs can be found here:

  http://docs.Oracle.com/CD/E11882_01/index.htm

  2. I will install Forms Builder and Report Builder (11.1.2.0.0) in another server (2008R2), so what I have to install WebLogic Server as well with it?

  Tools (Forms Builder, generator of reports, etc.) are not remote or web tools.  These must be installed on each developer's computer.  The installation of these tools does not require that WLS be installed first (on the developer's computer), but there is no need to be run unless the developer wants to apply locally for testing.  For a production deployment (multi-user), a similar concept will be used.  WLS will be installed first, followed by the forms and reports Services (runtime).  It will be on your remote server (medium level).  Software distribution you use will be exactly the same for the developer and the installation of intermediate level.  The difference will be in the options you choose during installation.  If you want to include manufacturers during installation, simply check the appropriate boxes when you are prompted.

  Also, if you plan to use the forms/States 11 GR 2, I recommend not using 11.1.2.0 and instead use 11.1.2.2, which is the latest version. F/R 11.1.2.2 installation requires that you first install WLS 10.3.6.  You should refer to the product documentation before beginning any installation. Specifically, carefully examine the product Setup Guide and Guide to the system requirements. The 11.1.2.2 doc library can be found here:

  • http://docs.Oracle.com/CD/E48391_01/index.htm

  3 what else do I need to install on this two server so that they work so that I can begin to migrate all the existing data, forms and States on?

  Looks like you've covered everything.  The granular details will be covered in the Installation and Guides to the system requirements.

  My recommendations:

  o ensure that each machine has at least 4gig of RAM

  o ensure that each machine has a static IP address before you start any part of the installation.  This can be done without a static IP address, but you must take additional steps (see Guide to Sys Req).

  o on machines where you plan to install WLS, make sure you have a 64 bit JDK installed first.  If you don't use a F/R 11.1.2.2, you must use Java 6.  However, if you decide to use 11.1.2.2, you can use Java 6 or 7.  Do not use Java 8 in all cases.

  When it comes to the designer, it must be installed on an old machine.  In General, I do not recommend to use it longer.  Although there is currently not a way to full migration out of it, you can use SQL Developer to manage the db objects that were created/used with it.  There are several MyOracleSupport documents that discuss the issue.  You can search the Knowledge Base of MOS to find or contact Support for more information.

• How to connect to an Oracle database using acrobat form field java script actions

  I have a PDF template with buttons and form fields. One requirement is that when a key is pressed, I want to connect to an Oracle database to change the data of the table inside the DB.

  I wrote "Mouse Up" event and set a Java script to run on this event. Java script I am trying to connect to the DB and Transact on the DB.

  Any ideas how to achieve this.

  Thank you.

  Assuming you are using Acrobat (or reader) XI or newer, it is no longer possible.

  There used to be a way to connect to a PDF file using a script and ADBC, a DB defined locally, but Adobe removed in favour of this option progressively and now it is completely obsolete.

  The only type of PDF files that can still do are those created using LiveCycle Designer.

  I had to go back and look at some documentation on our application server. If these steps do not work for you, you may need to click on 'Help' in your business manager and search for 'DADDY' or "Database Access Descriptor".

  According to these steps:
  1. connect to Oracle Enterprise Manager (http://finserv1:1810) - this would be the name of your server and port
  2. click on FIN_Midtier_1.finserv1 - this would be the name of your application server
  3. click on HTTP_Server
  4. click on Administration
  5. click on properties of PL/SQL (link at the top: application server: FIN_Midtier_1.finserv1 > HTTP_Server > mod_plsql Services)
  6. scroll the page to the Section of DAD
  7. click the Create button (right part of the screen)
  8. Select Type of DADDY of the general and click on Next (step 1 of 2)
  9. start to fill in the information of connectivity for DAD
  10 to precede the name of DAD or a location to a / pls in this example: / pls/findadgen
  11. username: enter the user name where the stored procedure (READ_PDF)
  12 password: enter the password for the user name that you just entered.
  13 Connect String is the database you want the DAD to connect to (the READ_PDF where)
  14. the connection string format is: TNSFormat because the connection string is resolved through tnsnames.ora
  15 get the language NLS value by running the following query against the schema/database this DAD is to be setup for:

  select value, parameter
    from nls_database_parameters
   where parameter in ('NLS_LANGUAGE', 'NLS_TERRITORY','NLS_CHARACTERSET');
  
  VALUE                                      PARAMETER
  ---------------------------------------- ------------------------------
  AMERICAN                                 NLS_LANGUAGE
  AMERICA                                  NLS_TERRITORY
  WE8ISO8859P1                             NLS_CHARACTERSET
  

  Enter the value in the form: _.< nls_characterset="">
  In our example, we have: AMERICAN_AMERICA. WE8ISO8859P1

  16. default Page: enter the name of the procedure that will be called if it is not specified in the URL. In our example, we use the name of the procedure: read_pdf
  17 Authentication Mode: the default value of Basic
  18. then click on Next (step 2 of 4) at the bottom right
  19. click on next again (step 3 of 4)
  20. click OK (step 4 or 4)
  21. your done. Don't forget DAD or any changes made to the DAD will not take effect until the server is restarted. Take the necessary steps to get this done.

  We then get an image with the chapters of dads who shows a name or location of/pls/findadgen, the user name, connect the string and status (green arrow - maximum)

• 1Z0-117: Oracle Certified Expert, Oracle Database 11 g Release 2 SQL Tuning

  Hello
  
  I failed the exam 1Z0-047 Oracle database SQL Expert"x 3 and will pass the exam in January 2012. I'm sure I'll spend this time :-) to 95%
  
  Now my question: what's next 1Z0-047? I only know how to leave 1Z0-047. I am SQL scripts to my work, but no DBA work and not of PL/SQL. So I guess that the "Oracle Certified Expert, Oracle Database 11 g Release 2 SQL Tuning" would be the next logical step?
  
  Is 'Oracle Certified Expert, Oracle Database 11g Release 2 SQL Tuning' too complicated for me (only have knowledge of the exam 1Z0-047). Because I don't have experience with the topics listed in the objectives, for the most part never heard talk about.
  
  What study guide?

  So I guess that the "Oracle Certified Expert, Oracle Database 11 g Release 2 SQL Tuning" would be the next logical step?

  I agree with you.

  The Oracle 11 g Release 2 database: review SQL Tuning is still in beta at least until November 24, 2012. Beta versions have been known to be extended. Even if this isn't the case, the examination of the production is not available before mid-January 2013 about. I had one experience with a beta. I hated and will never be another. There is little reason to do so, and most importantly (reduced cost) is not important to me because my company reimburses the cost of my essay, so I don't really care about the savings. They take several times longer to complete and I was a mess at the time that I finished that I did with a headache roaring through a large part of the review.

  That said - answering your question:

  1Z0-047 is a really complicated test. The questions and answers are designed to mislead. There is a reason for that. SQL, by its very nature, is a fairly simple language. Part of its appeal, is that it is easy to understand and write. If the people who wrote the essay was not gone to their best to make the deliberately convoluted SQL code, then it would not have required skills 'experts' to pass. It is much more difficult to read and diagnose poorly written SQL as well written SQL.

  I also took the test Application Express Expert: 1Z0-450. The questions that it were not written in a deliberately confusing manner. However, they had need intimate knowledge of the interface of the Apex. Because it was possible to write questions 'hard' without having to make them deliberately more obscure, the questions were simpler. I did not review SQL Tuning (as I said... no more betas for me), but I suspect that it will be similar to 1Z0-450 has enough information "at the level of experts" to write questions on that test will not attempt to write "hard" questions

  Is 'Oracle Certified Expert, Oracle Database 11g Release 2 SQL Tuning' too complicated for me.
  Because I don't have experience with the topics listed in the objectives, for the most part never heard talk about.

  Not sure what is in the test. This is excellent news. Student for the test will teach you a lot of new things about writing and tuning SQL. In my posts, a concept is repeated again and again. The value of certification is not make a piece of paper to stick in a workbook. The value comes to what new skills you gain in is about to pass the test. If you do not know the information and that you are not studying for the test, Yes, you will not pass. If you prepare for the test until you do understand the objectives, then you should be able to pass the test.

  What study guide?

  None does not yet exist. There is no doubt that I will write a review study guide. It won't be until some time after the test is in production. I do not publish guides for which I hold the certification. Do not wait for good. You can use the same exact source, I will use in his creation - the Oracle documentation. I guarantee you that all topics on the unique OE page and every single question that is under review are answered somewhere in the documentation.

• Help decide which version of the oracle database, I need

  I am trying to run Oracle APEX for a single site. All I want is to know if the limit of 11 GB data on Express edition can be used on a single table (can I have a table with 11 GB in there) and if what happens if I'm out of that?
  
  Also for a single server to the cheaper oracle database and apex license should solution that allows a storage more than that that I use? I'm confused because it says that there is a license of 5 minimal use?
  
  Does anyone know what version of oracle db is right for me?

  If you are using the express edition, you can put all 11 GB a table if you wish, assuming that you create all the other tables. Would not resemble a reasonable design - to me you would be probably better to standardize the data at least a little model - but it would work. If you have tried to exceed the limit of 11 GB, you get an error.

  If 'site' means ' public web site ", you need to use licensing by CPU. The cheapest option would be Standard Edition One running on a server that is small enough (I think two physical processors is the limit of material you need).

• Migration from SQL Server to Oracle database

  I have 2 questions:
  
  1. we intend to convert our sql server databases oracle OLTP databases. I tried to use SQL Developer to migrate a database of small sql server to oracle (size 5 GB) database. It was fine. When I tried to migrate to a different database (size 90G), it takes too much time. The problem with sql developer is I can not pick and choose tables. 250 paintings, I need to migrate tables abt 80 (the size will be abt 50 G). What is everyone can share their experiences, as appropriate, converting databases of size average sql server for oracle databases? other options?
  
  2. I intend to convert the sql server ddl to oracle ddl. I have tested bcp out and use sql loader to import the data. Right now I am manually creating the oracle tables sql server tables. I use http://download.oracle.com/docs/cd/E11882_01/gateways.112/e12069/apa.htm#BABCIIDI to convert the code. Are there other ways better to convert sql DDL DDL Oracle Server?
  
  Thanks in advance

  DDLS must be converted manually. Oracle is not SQL-Server.

  If for example, you have the option of partitioning, you should consider using the partitioning index and when it is possible. Not all tables must be hash tables. Do postpone you creation of segment or not? What type of tablespace? Set yourself free percentages and allows you to manage when the data block is on the free list and how much is reserved in the block of data to update rows in this block?

  There are many considerations to be taken with regard to the physical database design.

  Using BCP and SQL * Loader sound good. SQL * Loader is fast and scalable - use it to load up to 3.6 million lines every 60 seconds. Direct and parallel charges will give the best performance in this regard (assuming that the underlying table structure and use supports this approach).

• The CPU is not powerful enough for Oracle database 11g?

  The CPU is not powerful enough for Oracle database 11g?
  
  I installed the datatase Oracle 11 g on my host by using the default configuration of oracle yesterday. Today, I find some the alert message: "CPU usage is 86,79%, through attention (80) or critical (95) threshold.» The average value of the CPU usage is 80.85% and I have to wait for more than 10 seconds for opening a page of the EM.
  My host is HP workstation xw4200. CPU is 3.4 GHz. No other applications on that host.
  I want to know: what is the main reason for the shortage of CPU resources? Because the database Oracle 11g itself is exhausting CPU or because there are a few configuration issues?

  qkc wrote:
  1 is it true that most of the CPU is exhausted by the EM control tool?

  It's quite possible.

  It is also one of the reasons why we encourage people to drop EM Database Console and switch to EM Grid Control. The burden is then on another server.

  2. why this index has been added in advance by Oracle Corporation? It does not seem that each tool is set up perfectly in advance.

  It was probably not required under ideal conditions, in which it has been designed and tested.

  Why is your environment not identical to the designed conditions that use Oracle? ;-)

  In my view, that deserves both. Here are the links mentioned above:

  The Oracle Certification candidates who provide their OPN company identification number when you register for and successfully select Oracle Certification exams - in addition to winning the basic certification - also handed the Oracle Partner Network Certified Specialist designation for this area also.

  user507531 wrote:

  Meanwhile, I would also like to know if there are any designs / charts, high level design, low level of design, ER diagrams to create before you start any development of Oracle plsql.

  It depends on the environment, work in and value standards. Some expect a case of use (UML) before a single line of code is written. At the time of Cobol, an organizational chart was generally expected.

  With some new programming approaches, the test cases are often used to define the program (as in turn, which defines the objectives of the program).

  ERDs come with database design - with the design of the PL/SQL program. You can use an ERD for a PL/SQL program, but is not part of the design of a PL/SQL program. It describes the database instead.
