• Stages of design of database

  Hi all
  
  I am new to learn oracle database design. Please can someone give me the steps or the procedure that we can easily to design the new database oracle. ?
  
  Kind regards

  Are you referring to the design of physical database (implemented disk layout, the locations of files etc.) or logical database design (schema, table structures, index, etc.)?

  Based on your requirement, the answer will change.

  But in simple terms, it would be better if you could take a course in local universities or colleges that have database THE program design. It is not possible to summarize the design of database in a few lines.

• How to choose a database schema to use for a file of sequence?

  I have several database schemas on my TestStand system, and when I select a movie file that I need to position the schema for the results entered into the database correctly.
  I use a SequenceFileCallback for DatabaseOptions in my file of sequence and in that, I set Parameters.DatabaseOptions.DatabaseSchema.Name = 'xyz', where xyz is the name of database schema to be used. It does not, and it reports an error that it cannot be loaded or the file is maybe damaged. This feature works, or should I just a mistake in what I put this equal to?

  Evan... It turns out that your last point: 'Make sure you use quotation marks around the name of schema, no simple markings as in your message.', has solved the problem. Funny it did not report a single error with the brands. Thanks for the quick response! PLF

• How to use references from web third party service with service Cloud Computing to Oracle database schema

  APEX 5.0

  Cloud Computing service for the Oracle database schema

  
  

  I'm in the middle of do a proof of concept.  Basically, I need an application with security of the stored data, UI, user, data loading, and able to post data via an external web service said.  It seems that with the database schema Oracle cloud service, it is not possible to use web service references that are not in the field.

  If I try to use a service via http reference, I get:

  ORA-20987: APEX - the requested URL was forbidden. Contact your administrator. -Contact your administrator of the application.

  If I try to use the same reference service via https, I get:

  ORA-29273: HTTP request failed

  ORA-06512: at & quot; SYS. UTL_HTTP & quot; line 1130

  ORA-29259: end-of-input reached

  I read somewhere that cloud services only https can be used.  Is this true?

  And then I read somewhere to use the protocol https, the portfolio must be configured to store certificates, etc.  However, I read somewhere else that the portfolio cannot be configured because there is no access to the instance database with the Oracle Cloud Computing database schema service.  Is this true?

  If both are true, how can I make a call to post data to an external web service?  Or do I need to use a different Cloud Computing service?  Or do I need my own instance of Oracle DB?

  Any help would be great.  Thank you!

  It turns out there was a problem with the remote rest service.  After successfully calling a rest service that was created using SQL Workshop, I tried different remote rest services and they all work.  Sorry for the confusion.  I thought it was very strange that the schema of database service wouldn't be able to do it easily.

• Oracle Cloud Service database schema... Apex Cloud_Scheduler & E-mail procedure

  Professional Hello, etc. of users experienced Apex.

  I am currently using the oracle database schema cloud service, which is related to my extension service java saas.

  I have a requirement to send reports to certain accounts of e-mail per day. Hence the need to use the CLOUD_SCHEDULER API, APEX_EMAIL API and a custom "Get_REPORT"... return blob function to convert the sql result set to CSV file to be attached to e-mails.

  1 function GET_REPORT returns the BLOB as the query results set CSV file. Autonomous œuvres

  2. I created the 'SENDEMAIL' procedure that accepts the responsibility of the sender and receivers email address, subject and a BLOB (GET_REPORT) to be attached to the email. And sends APEX_MAIL. PUSH_QUEUE. : This method works stand-alone.

  3. I created the "ScheduleCSVToEMAIL" procedure that accepts the e-mail to, from, cc, tablefiltertext, tablename: this procedure combines 1 and 2 as below...

  SQL_TEXT := 'SELECT * FROM '||TABLE_NAME||' WHERE ' || SQL_FILTER ||'';
  REPORT := GET_REPORT(SQL_TEXT);
       SENDENDVI_MAIL2(TO_ADDR,COMMA_CC, FROM_ADDR, EM_TITLE,EM_TITLE,null,null,REPORT,null);
  

  above works fine when run standalone.

  4. I created CLOUD_SCHEDULER PROGRAMS as below

  BEGIN
    CLOUD_SCHEDULER.CREATE_PROGRAM(
    program_name => 'emailtest1',
    program_action => 'SENDENDVI_MAIL3',
    program_type => 'STORED_PROCEDURE',

    );
    CLOUD_SCHEDULER.DEFINE_PROGRAM_ARGUMENT(
    program_name => 'emailtest1',
    argument_position=>1,
    argument_type=>'VARCHAR2',
    DEFAULT_VALUE=>'[email protected]'
    );
    CLOUD_SCHEDULER.DEFINE_PROGRAM_ARGUMENT(
    program_name => 'emailtest1',

    argument_type=>'VARCHAR2',
    DEFAULT_VALUE=>'[email protected]'
    );
    CLOUD_SCHEDULER.DEFINE_PROGRAM_ARGUMENT(
    program_name => 'emailtest1',
    argument_position=>3,
    argument_type=>'VARCHAR2',
    DEFAULT_VALUE=>'[email protected]'
    );
    CLOUD_SCHEDULER.DEFINE_PROGRAM_ARGUMENT(
    program_name => 'emailtest1',
    argument_position=>4,
    argument_type=>'VARCHAR2',
    DEFAULT_VALUE=>SYSDATE||'_ENDVI_VH_INSURANCE'
    );
    CLOUD_SCHEDULER.DEFINE_PROGRAM_ARGUMENT(

  END;
  

  and

    CLOUD_SCHEDULER.SET_JOB_ARGUMENT_VALUE('emailtestrun1',2,'[email protected]');

    CLOUD_SCHEDULER.ENABLE('emailtestrun1');
  END;
  

  Above, executed but it obviously it didn't, I asked the table "USER_SCHEDULER_JOB_RUN_DETAILS" and I got the reason of failure below.

  ORA-20001: This procedure must be invoked from within an application session. ORA-06512: at "APEX_040200.WWV_FLOW_MAIL", line 339 ORA-06512: at "APEX_040200.WWV_FLOW_MAIL_API",

  Please help what I do to get my work requirement.

  Note: I already tried to use the Scheduler in the format below, who gave the same result

  BEGIN
    CLOUD_SCHEDULER.create_job (
      job_name        => 'ENDVI_AUT_EM_ROCKET',
      job_type        => 'PLSQL_BLOCK',

      repeat_interval => 'FREQ=MINUTELY; INTERVAL=3;',
      enabled         => TRUE);
  
  
    CLOUD_SCHEDULER.set_attribute (
      name      => 'ENDVI_AUT_EM_VH_INSURANCE',
      attribute => 'max_runs',
      value     => 20);
    CLOUD_SCHEDULER.enable(name => 'ENDVI_AUT_EM_VH_INSURANCE');
  END
  

  Right answer

  Hi oladslw,

  You must perform an additional step before calling the API APEX_MAIL outside an Application Express application. Two ways to achieve this are described in the APEX_MAIL documentation (see first Note) and in the APEX_UTIL documentation. Another way is:

  for c1 in ( select workspace_id
                from apex_workspace_schemas
               where workspace_name = sys_context( 'userenv', 'current_schema' )
                 and rownum = 1 ) loop
      apex_util.set_security_group_id( p_security_group_id => c1.workspace_id );
  end loop;
  

  The code above retrieves your workspace_id of the dictionary of the current schema-based APEX of (your), then sets the security context of APEX. After that, you will be able to call APEX_MAIL in a same database session.

  Thank you

  Apparently, this behavior has changed. There is nothing in the notes of publication on this subject.

  I guess the way it worked in 12.1.2 was wrong as you shouldn't have access to objects without property rights.

• JCA database adapter issue because of the dependence of database schema

  Hello
  
  I use the database JCA adapter to call a stored procedure. The adapter uses the schema of database name while calling the stored procedure. The schema name is added to the namespace XSD, wsdl files.
  If I have to use a different database schema name, how can I change the code without a lot of change.

  If you import a single schema, you could just start importing and then correct errors (even back the schema and re - import).

  In any case, this document is more than enough:

  http://www.orafaq.com/wiki/Import_Export_FAQ

  Just a suggestion: use the buffer parameter when importing:

  IMP BUFFER = 10000000...

• Design of database for a helper.

  Hello does anyone know
  Design of database for a helper.
  ERD
  Features and business rules
  ?

  The best way to approach a design of database is to write a specification for the application. The document, which deals with the assistance of technicians will do. In the process of determining what pieces of information, they work with. When you have written complete specification, you can start then group the items of information they work with. For example, a ticket can have a number, status, priority, and a person who is associated with. The person to which is entrusted the ticket will have a name, phone number, email address and a list of technical skills.

  So in this simplified example excessively, we might have a table that contains the information of the ticket, a table that contains information about the technicians and an array of skills. Then ask free questions as "a ticket can be handled by more than one technician?" "A technician can manage more than one ticket? Can a technician cause several skills? "In this way, you can begin to see relationships on a one-to-one, one-to-many and many-to-many that exist.

• How to find a table, using the name of the column in the database schema

  Dear all,
  
  Please help me on
  
  using the name of the column, how to find a table name in the database schema.
  
  Thanks in advance

  Hello

  You can query the data dictionary views all_tab_columns and user_tab_columns.
  For example, to find the tables in the scott schema have called deptno columns:

  SELECT  table_name
  FROM    all_tab_columns
  WHERE   owner           = 'SCOTT'
  AND     column_name     = 'DEPTNO';
  

  Remember that anything inside quotes is case-sensitive.

  The all_tab_columns view has one row for each column in each table (or view) that you have the privileges to use.
  The user_tab_columns view is a subset of all_tab_columns, containing only your own tables (and views).

• Unifying database schema structure 15.1

  
  Hi all

  Greetings!

  I have a silly question. Do we have a schema structure to unify 15.1, as we have for P6 EPPM in the media of documents folder in the folder mapping and schema > > schema Docs > > xml file & eppm_html, that shows us the table names, field lengths, dependencies, and primary and foreign keys?

  I saw some downside however mapping and integration purposes is not very useful, because we need to navigate tables in PDF format. You have a schema structure and dependency table based on the web?

  Thank you

  Bala Ganesh K

  Due to the fact that the unifying database structure changes depending on how you design unifying, we do not have a general structure of schemas and tables available.

  You can see this document for more information on the elements of Out-of-the-box in the unifying database:

  http://docs.Oracle.com/CD/E59489_01/English/Mapping_and_Schema/Reference_Guide.PDF

  In addition, you can access the ER seen in the unifying workspace Company, which provide information about the tables that are available to you in the database. Please see the KM article that describes how to access and use views ER:

• Database schema error - 2147467259

  Hello community,

  Using 32-bit Teststand 2014.

  When executing my movie file, a digital step in my sequence failed.

  After the failure of step, accordingly, my sequence stops the test and run cleaning.

  I'm then prompted with the error message, see image attached, when Teststand save my data in the database.

  I opened my database SQL and noticed that all the previous steps "Spent" have been registered in the database fine but the step failed has never been registered.

  My scheme is configured to record the steps Passed and Failed.

  I solved my problem.

  I had the STEP_RESULT measured value starting from the game as a float of patterns of treatment results, but the step which has not led to a NAN value.

  I changed the value to a string in order to manage the numbers and strings.

  Create a database user has access SELECT through patterns. Then, use a Pool of single login with this user id and check the box to fully qualify table names, so that when the SQL generated it precede patterns correctly. You can create patterns according to the needs, and it will work fine.

• Can a database instance cause several database schemas?

  Since coming from SQL Server I have red the concept of the Forum and got a little confused with the instance, schema, tablespace concept.

  If I get it up to now, Oracle has several layers.

  Database instances are as independent SQL servers started from the Oracle server.

  Each database instance can contain different data bases. OR a database is not owned by a histance, the mountain just a (confused about this)

  Each database can have different storage spaces.

  I created this pixture comparison, something like that?

  http://img191.imageshack.us/img191/7639/jv3z.jpg

  • a single instance can open a database only
  • on the other hand, a database can be opened by multiple instances on different servers in a clustered (RAC) environment
  • a database can have mutiple patterns (that's what SS called "database")
  • Each schema has objects that reside in one or more storage space (a single object is always 1 tablespace)
  • A tablespace is just a logical container
  • A tablespace is composed of one or more data files.
