What is the use_sigio parameter in oracle 11g R2

• What is the problem with my Oracle reports parameter?

  Hello

  We use a PL SQL package that allows the user to select the report you want Oracle and associated parameters.   While the control is passed to Oracle 11 g reports.

  The requirement of one of the reports is to enable more detailed codes be selected by the user and then shown.  The detailed code is an alphanumeric field that can hold between 4 and 6 characters.

  If my data model looks like this

  SELECT student_id

      FROM my_view

     WHERE detail_code IN :p_detail_code;

  and the parameter that I'm passing to Oracle reports looks like this (when I view the source HTML code)

  & p_detail_code =('1001','1002')

  so no record is selected.

  However, if my data model looks like this, I get the records you want:

  SELECT student_id

    FROM my_view

  WHERE detail_code IN ('1001', '1002');

  We have Oracle Database 11 g Enterprise Edition Release 11.2.0.4.0 - 64 bit Production.

  Please tell me what is the problem with my setting.  Thanks a lot for your help.

  This isn't how you can use in. See this example on how to solve it with the digital settings. If your setting is a character, you need to change this.

  In fact, when you simply enter 1,2,3 as an input parameter, you actually create this query:

  Select *.

  from my_table

  where num_column in ("1,2,3")

  Use rather a lexical parameter:

  Select *.

  from my_table

  & p_where

  In the parameter after relaxation shape, build the lexical like this:

  :p_where := 'where num_column in ('||:p_param||')';
  

• In passing the huge parameter to oracle procedure have a performance hit?

  I have a script attached, in which I am trying process/XML parsing in a table (STAGE_TBL) in the XMLTYPE column and insert the data analyzed in another table (PROCESSED_DATA_TBL). The XML file can be huge up to 2MB, which translates into approximately 2000 + lines of analyzed data. The issue I see is when I pass an XML object to a procedure (STAGE_TBL_PROCESS) to analyze its takes about 10 seconds per XML, but rather than from XML if I directly pick up table in the procedure (STAGE_TBL_PROCESS) passing the ID to be about 0.15 seconds. According to the document while params are passed by reference, so why is this variation of performance?

  Details of database Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64-bit version of PL/SQL Production 11.2.0.3.0 - Production "CORE 11.2.0.3.0 Production" TNS for Linux: Version 11.2.0.3.0 - Production NLSRTL Version 11.2.0.3.0 - Production

  In version 11.1, Oracle introduced a new model of storage for the data type XMLType called XML binary.

  Binary XML become the default in 11.2.0.2, to disparage the old storage based on CLOB.

  Binary XML is a format optimized after analysis for the storage and treatment of the XQuery.

  When an XQuery expression is evaluated (through for example XMLTABLE) on an XMLType column stored as binary XML, Oracle can use an ongoing evaluation of XPath that surpasses the query even crushed a transitional XMLType of several order of magnitude.

  You can see that in the action plan of the explain command:

  SQL> SELECT E.*
    2  FROM stage_tbl t
    3     , XMLTABLE('rp_send/rp_sendRow' PASSING t.xml_document
    4         COLUMNS store VARCHAR(20) PATH 'store'
    5               , SalesNo VARCHAR(20) PATH 'sales'
    6               , UnitCost NUMBER PATH 'cost'
    7         ) E ;

  --------------------------------------------------------------------------------
  

  When the query is executed on a passenger XMLType (for example, a parameter, or a PL/SQL variable), Oracle cannot run the binary model and use a functional assessment based on memory of the XML DOM-like representation.

  You can see that in the plan to explain it by spoting a 'COLLECTION ITERATOR PICKLER FETCH' operation.

  So what explains the difference (in your version) between treatment from a column of XMLType (stored in binary XML format) or a variable or a parameter.

  From 11.2.0.4 and beyond, things have changed a bit with Oracle, introducing a new transitional level of optimization on XMLType.

  The plan of the explain command will show a "XMLTABLE ASSESSMENT' in this case.

  You mention that you are using Windows, but if you are and that you have installed the oracle database software and NO service like OracleService , then you do not have a database. But then, why the hell you you ask about this? If you do not want the database software, why don't you just go ahead and uninstall it? And how is it, someone can come and something on your server and have no idea about it?

  Be sure to distinguish between the terms and the database schema. Other products, make them bad. It would be a HR diagram (or a user, which is the same in Oracle). If you do not need to use the database Wizard, unless you are working with a new host with no database.

  A simple way would be to get the DDL to create the HR schema and modify it for your own. It can be extracted from your database in several ways, or you can copy the hr_cre.sql to your own script and change. The two ways are educational, and you can google for instructions.

• What is the patch appropriate for Oracle 11 GR 1 material to Oracle 11.1.0.7 Solaris

  Start with, you can try to understand the difference between

  (1) a patch and a group of patches.
  (2) different flavors of patch - one-offs, CPU, power supply

• What is the transferred parameter of the report navigate?

  Hi guys,.
  
  I have a question. When I put a column in the report as to navigate to the other report is the transferred parameter domain name (RecordType.Name) or the value of the actual field?
  
  Since I was a report called "List of innovative activities" fitted with a 'MedEd.Name' as 'is fast ". And I put the "MedEd.Name" field in another report to access the 'innovative list', it works. While I create another text field, set its value by default equal value [< MedEd.Name >] and made navigation on this field, it does not work, the report reveals the full results.
  
  
  Kind regards

  Hi, the field on which the filtering should be applied is determined by the name of report Source fields and the actual filtering is done by the value of the field. It may be useful

• Controls all the preconditions fails on Oracle 11g R2 on Solaris 10 SPARC

  Hi all
  
  Wonder if anyone has experienced this problem before when installing Oracle 11 g Release 2.
  
  I'm trying to install Oracle 11 g Release 2 (11.2.0/1/0) for Solaris 10 SPARC, respecting the Oracle® Database Setup Guide fast 11g Release 2 (11.2) for the Solaris (SPARC 64-Bit) operating system that is located here:
  
  http://download.Oracle.com/docs/CD/E11882_01/install.112/e10863/TOC.htm#BABHECFG
  
  I created my users and groups, gave the permissions set ORACLE_BASE, added the oracle with projadd project and set the required parameters it and in/etc/System too just incase.
  
  When I run. / runInstaller, on the section due diligence, it seems to fail pretty much everything and I don't know why...
  
  His same say the oracle user does not exist (well I had to run the installer as oracle!), oinstall, s/n, etc as well. Complains about limit parameters and settings of perimeter of core that are defined. He even complains that you don't find the architecture of the BONE and are invisible to the packages that are installed. It basically seems as if his tent all these checks but found nothing properly.
  
  All the expected and actual values are s/o too, usually even if it should appear. Someone had this kind of problem or have any idea what could be the cause?
  
  I think its got something to do with Solaris 10 SPARC or some sort of requirements, which is even not mentioned in the Oracle documentation.
  
  Thank you very much
  
  Kind regards.

  Check the doc of MOS. It has the required information and the reference to other documents too.

• What is the official reporting tool Oracle JDeveloper ADF applications.

  Hi all
  I'm on the migration of Oracle Forms and Oracle JDeveloper ADF reports.
  I have read several books on JDeveloper and ADF and I take. Now what I will use to create reports; tool Oracle to create reports, that is tightly integrated with JDveloper and ADF comparable to the relationship between Oracle Forms and Oracle reports.
  I will be grateful for your response.
  Best regards,

  There is no tool tightly coupled with jdev. Tool of oracles of choice would be BI Publisher (I guess). However, you can use the reports jasper or any other tool to report as well.

  T2KDEV is set to the type of terminal you are using. If you are using openwindows; Xsun if you use X windows.

  Is defined on the type of terminal you are using. Note: If you are using openwindows, you may need to redefine the variable TERM to the Sun (instead of cmd-Sun) and you must run a shelltool ORACLE.

  TWO_TASK is located where the ORACLE Server can be found, and will normally be the name of the database instance. This variable allows to simplify the command line to start the ORACLE tools.

• What are the best support for Oracle build tools?

  Hello
  I tried hammerora the other day and I was wondering what another generation of load (stable) there are tools for Oracle?
  
  I would like to generate different types of load to the database for test and demonstration purposes.
  
  What tools do you use / know?
  Thank you!

  At the Conference the user Oracle the other day, Doug Burns Group (which featured the 10 g / 11 g Conference Performance Analysis) recommended "SwingBench" generator to load. Check out www.dominicgiles.com
