• Area of private use in the Oracle database

  Hello

  one of my customers have very specific needs. In this case, it has its own "characters". It uses Latin characters and certain characters. Their data are mixture of these characters. Their own characters are not in Unicode format and we have specific policies.

  These specific characters will be in the private use area, but I don't know if and how the Oracle database support unicode private use area.

  Oracle database support unicode private use area?

  And what sorting, filtering data? What classification is applied?

  Does anyone have experience with characters in the private use area?

  Thank you

  Fabrice.

  Oracle supports Unicode PUA you can store codes of PUA in a database AL32UTF8 and you can treat strings containing characters without special considerations. PUA characters are classified into letters in the Oracle database.

  Oracle maps the characters (EUDC) user of various character sets defined multibyte (JA16SJIS, ZHS16GBK, ZHT16MSWIN950, KO16MSWIN949, etc.) to the characters of PUA. These characters are also used by the former Hong Kong HKSCS extension mapping. If supporting user-defined characters in PUA is not a problem for the customer, they can use the standard plane 0 (BMP) PUA [U + E000 to U + F8FF] in their purpose. However, to avoid conflicts with existing maps, they should put their characters in plane 15 PUA [U + F0000-U + FFFFD] or plane 16 PUA [U + 100000-U + 10FFFD]. The downside is that the planes 15 and 16 require four bytes per character in AL32UTF8 compared to three bytes for plane 0.

  The classification applied to the characters PUA is the same as that applied to the other characters in a given environment. The order of the characters PUA in the given classification, depends on the type of snack:

  • In BINARY classification, the comparison is obviously based on binary codes. The order depends on encoding (AL16UTF16 vs AL32UTF8), especially for aircraft 15 and 16 PUA plane.
  • In monolingual rankings (which are not well suited for Unicode characters anyway) PUA are generally ignored in the sorting (but does not) than the characters defined explicitly in the given classification. Compared only among themselves, they use the UTF-16 Binary order.
  • In multilingual characters rankings PUA are generally classified after all characters defined explicitly in the rankings, which are characters from scripts (Latin, Cyrillic, Greek, Georgian, Armenian) Europeans and, in some rankings, an East Asian script. Between them, they are classified according to AL16UTF16 (= UTF-16BE) binary collation.
  • In the UCA, the characters multilingual rankings PUA generally are classified into once all characters defined explicitly in the rankings, which are usually all defined Unicode characters. Between them, they are classified according to AL32UTF8 (= UTF - 8) binary collation. Note that the UCA rankings are new in the database Oracle 12 c.

• Record great shape data in the Oracle database

  Hi all

  I have a question as to how we store a large xml for example more than 10000 bytes in the oracle database. I tried to use varchar, but the length is limited to only 4000 bytes. Could someone let me know how to achieve this.

  Basically what I'm doing is in adobe livecycle workflow I will get the user entered data in the form as formData (xml) variable and I want to keep the same for any future reference. I need to use the same data to fill the form again in the future.

  Thanks in advance.

  I had handy MySQL, so I did it using that and attached here is a sample. For Oracle, this is mission for you as well as recovery.

• How to start the oracle database server and its client in windows 8

  Hi all

  I am a new entry in this forum and I am a beginner with oracle database.

  I always used SQL Server as the database, and it was easy to use after installation.

  With management program configuration of SQL Server I could to start service SQL Server (SQLEXPRESS) and the database server start!

  With SQL Server management studio, I was able to launch the client application, then was to establish a connection to the server and everything worked great!

  Now, how to work with the oracle database?

  I installed the oracle server and client version 11g R2 in windows 8, but how do I start the database?... and how can I start the client application to query?

  best wishes in advance.

  PS: Sorry for my English.

  If you are on the same machine, the only service that you absolutely need to start is the database service.  In your case OracleServiceSYSDBA (hmmm... How did you find with this name?).

  For queries, you can use SQL * Plus which should also be installed.  If you want something GUI, you can use SQL Developer (you need to install separately I think).

• New to the oracle database

  Hi all
  I just joined this forum.
  
  I work on SQL server and have everything just one year of experience in IT.
  Interested to switch to the Oracle database.
  I want to do a basic certification next to oracle database developer.
  I'm not able to choose the path of certification in the oracle site.
  
  Please guide me which is the best.
  
  Thanks in advance!

  Hi, René.

  Welcome to the forum!

  This isn't really a question of SQL or PL/SQL; It is more a question of certification. I think that you will have a better response if you post your question in the forum of Certification:
  Community certification

  If you do, mark this thread as "Answered" to keep people (including you) by looking at the two threads.

  Yiou might add more details on what kinds of things you want to do in Oracle.

• How do I get the name of the web page in v$ session table in the Oracle database

  We have asp.net web application hosted on IIS (windows) and the connection to the Oracle (10g) database.
  
  
  When I query the table v$ session in the database as a Jr.DBA, I don't see the name of the program as "w3wp.exe.
  coming from the computer host IIS (web server).
  
  Now, it is difficult to diagnose as session in the database that refers to what web page in the web application.
  
  If I have 10 web pages open in my web application connecting to the Oracle database, now if I wanted to go
  session info, when I browse the v$ session all it shows me what "w3wp.exe.
  
  Now is there a way to get the name of the web page in the session of $ v.
  
  (maybe he needs a few changes to the code in the application web asp.net, change in the configuration of IIS web server as well).

• Question about the Oracle database resource management

  Good evening
  I have a question about Oracle database Resource Management (DRM) for Oracle Database 10 g. I had an incident which, in a development/UAT environment (different instances, same box, don't ask), a developer wrote a wrong SQL statement that consumed 99% of the CPU. Currently, there is no limit of resources on two cases of db, and the developers don't want limits. However, my manager wants a method to prevent something like this does not happen. If I use the Oracle database resources management, create a consumer group (called "DevEnv") at 40% CPU usage, what will happen if a user of DevEnv runs a bad SQL statement that normally consumes 90% CPU again? Anyone would take a different approach? Thank you.
  
  Sincerely,
  Sho Fukamachi

  If users in the case of "db_uat" use 60% CPU would be users who belongs to DevEnv pending 'db_test' cannot be used more than 40% CPU, so their queries become slower at their end? I would like to know if this behavior works the same in an environment of multiple instances. Thank you.

  Yes, because the available processor would be 40%, they use more, while.

• Convert flat file to XML document and store it in the Oracle database

  First of all:
  I have a flatfile and created an external table to read this file in Oracle
  Now, I want to create an XML document for each line and insert in the Oracle database, I think as XMLtype.
  Could you please give me some information/steps.
  
  Second:
  Are there performance issues, because every day, I need to check that the XML document stored in the database against the next file.
  Thank you.

  I won't tell it not in the same words that Marco used, but your solution is impassable and an invitation for bad things to happen.

  Wait miserable performance, and you will not be disappointed.

  The concept of total flexibility works up a code that you depend on has no idea what to do with what is playback.
  Will happen to enough short term and is roughly the equivalent of the absurdity of Java to be independent of the database.

  I would recommend you take the concept and consider, with your data volumes, something more likely to succeed.

• Target of hyperlink connects since the Outlook file in the Oracle database mail

  Greetings.
  Lack of permissions, I can't create text file on the UNIX server.
  This will not be changed.
  I saved the file in the Oracle 11 g database.
  
  I want to send e-mail to PL/SQL with attached file.
  No UNIX don't scripts at all.
  
  It's a big file.
  Thought has crossed my mind.
  
  Can I send e-mail to PL/SQL with a hyperlink that connects to the file that is stored in the Oracle database?
  The target of the link is a file stored in the Oracle database.
  
  Did anyone done this before?
  
  Let me know your ideas.
  
  Thank you.

  Can be done using UTL_SMTP or more recent UTL_MAIL.

  Attachments to emails are just that - the content of the file is attached to the body of the mail. Mail arrives at its destination, the mail reader recognizes the attachment and allows it to be saved to disk (or open/read).

  It's standard stuff... See MIME for more details on how to build a body of message with attachments.

  Yes. You need a web server that has been configured with Oracle "+ access +"-the default is using the Apache Oracle server which includes a module called mod_plsql. This module allows the web browser to use a URL that refers to a procedure from PL/SQL web enabled in a specific database schema - and pass parameters (as part of the URL query string) to the proceedings.

  You can also use Oracle EPG (Extended procedure gateway according to me, is what does the acronym). This provides a web server directly within the Oracle instance using Oracle XDB (integrated database of XML). It also has a module of type mod_plsql which provides that a web interface (via http) enabled PL/SQL procedures.

  This procedure can be a procedure "+ document download. Oracle provides a system procedure called WPG_DOCLOAD.download_file ()+ you can use inside this active web PL/SQL procedure. This will return the contents of the blob/clob as a 'file' in the web browser.

  For example, a download web-enabled simplistic procedure will look something like this:

  create or replace procedure downloadFile( fileName varchar2 ) is
          b       blob;
          mimeType varchar2(50);
  begin
          select
              file_content, mime_type  into b, mimeType
          from my_documents where file_name = fileName;
  
          OWA_UTIL.mime_header( mimeType, false );
          HTP.p('Content-Length: ' || DBMS_LOB.getlength(b));
          OWA_UTIL.http_header_close;
          WPG_DOCLOAD.download_file( b );
  end;
  

  The URL will look like this:

  http://my-webserver.my-domain.com:7777/pls/ora/scott.downloadfile?filename=somefile.doc
  

  where:
  Scott.DownloadFile = name of the PL/SQL procedure
  filename = somefile.doc = name values of the parameter to pass to the procedure

• connection / disconnection of the oracle database

  Hello
  I looked upwards and downwards in the documentation of oracle for a good reason why we should not connect to the oracle database, delivery time of 4 or 5 Oracle sql disconnect, reconnect 4-5 sql statements and disconnect again(using sqlplus).
  What I currently have is an application that has this kind of behavior that would be as connect/disconnect to the database over 300 times in 25 minutes.
  I know that this is not scalable, but would like to show the programmer in the oracle documentation that is not a recommended bestpractes.
  Any help will be appreciated.

  What you can explain the developer that is whathappens when a connection is given and terminated, the concept of the PGA and server allocation and dealloction process. You can include more use of server resources when all that happens. Once this part is well to him, you can tell him that hisapplication this constant opening and closing of session, it don't let not the server works optimally as morethan optimize work of its apps, server would be busy giving him the connection later by removing its connetion.

  Just take a look at the documentation and found this guide, PT
  http://download.Oracle.com/docs/CD/B19306_01/server.102/b14211/design.htm#CJHFIHFC

  >
  Factors that may prevent a linear scaling include:

  Configuration, implementation and poor application design

  The application has the greatest impact on scalability. For example:

  The poor schema design can cause expensive SQL that do not evolve.

  Poor transaction design can cause problems of locking and serialization.

  Bad connection management can cause periods of poor response and reliable systems
