  Hello

  I think it need more process, maybe you need some settings in the database, for example, you can see follow these settings:

  1. Select name, value of the parameter $ v where name like '% session ';
  2. Select name, value of the parameter $ v whose name as "process % ';
  3. Select name, value of the parameter $ v where name like '% of transactions;

  Accordint to this...

  You can the chance these values...

  I hope that this information will be useful for you.

• 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.

• How to find the name of the Oracle database server?

  People,

  Hello. I installed Oracle Database 11 g 2 OS Oracle Linux 5. The installed directory is/home/user/OracleDB_Home and/home/user/OracleDB_Base.

  Host name is "mylinux". Name of the database instance is PT853.

  I use "mylinux" as the name of the database server, it does not work. I use another way to do as below:

  Export ORACLE_HOME = / home/user/OracleDB_Home

  Can I use "mylinux ORACLE_HOME" as the name of the database server, it does not work either.

  
  My question is:

  How to find the name of the database server Oracle with Oracle Linux 5 OS?

  
  Thank you.

  You must learn the basic of database Oracle.

  Please don't regard it not same as SQL server in terms of configuration.

  You never specify the database server name in Oracle.

  You specify the host name in only two places, 1) Tnsnames.ora/JDBC/ODBC (or any client you want to connect) and listener.ora) 2.

  There was nothing called specify the name of the Oracle database from an oracle database server.

• 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.

• PDF files in the Oracle database

  First all the Hi and thanks to all the gurus of this forum to provide non-stop services to solve problems at the global level.
  
  I'm using Oracle Database 11 g - R1 with Oracle Application Express 4.1.
  
  My clients (end-users) can visit to download PDFs in the database via a built-in Oracle Application Express application.
  
  All of a sudden ".dmp" size increased rapidly from 360 MB to 2.7 GB and everything that happened due to downloading of PDF files.
  
  I want to know it's alarming for the Oracle database? Because I'm in doubt, users have a lot of files to download, Services of Oracle database that will / Performance will be disturbed by the increase in the size of the database or Oracle database server could be crushed?
  
  
  Please confirm. Thanks in advance.
  
  Looks: Mohammed Uzair Awan

  Performance may be affected.
  Backup time would increase.
  Backup space (disk / tape) would increase the requirements.

  There should not be a 'crash' of the database
  As you run 11 GR 1 material, I assume that you do not run the Express edition.

• 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.

• Why use Oracle Grid in the oracle database

  Hi experts,

  In fact in my workplace, we use normal database (use not the grid). I want to know why we use the grid in the oracle database. all that the advantage of it.

  Reg,

  Thomas

  You might have a grid of database servers (access to the shared storage) or application servers.

  You can use the Grid control to monitor and manage multiple database / application servers.

  10g and 11g and 12 c facilities grid Infrastructure is installed to facilitate the DSO (is not part of the 10g GI) but a part of the 11 g and 12 c GI and Clustering.

  Then, depending on the context "grid" can refer to another product.

• 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).
