• 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

• 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.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", 
  line 97 ORA-06512: at "F1ZKNWJD2RE1.SENDENDVI_MAIL3",line 56
  
  

  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',
      job_action      => 'BEGIN SCHEDULE_CSV_EMAIL(''G_EMAIL_VHROCKETDETAILS'',''[email protected]'',''[email protected]'',''[email protected],[email protected]'',NULL,SYSTIMESTAMP||''_TEST SCHEDULE_CSV_EMAIL'',NULL,NULL,NULL); END;',
      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

  Hello
  Can you please let me know what is the tables are actually created in the SCHEMA (Shared services) or EAS in the relational database. It's when configuring EMP that tables are automatically created in the database?

• I have an old relational database, Base of power. Need to transfer to new computer

  I have an old relational database, basic power, written for the old BACK who also works with Windows 3.2 and Windows 95.  I just got a new Toshiba laptop, running windows 7.  He needs to do to run this program.  I have old professional documents on it and a large geneagology that I am trying to keep up to date.  Can you suggest one new relational database that are other than the access that will allow me to transfer my old files?

  You might try DOSbox http://www.dosbox.com/

  If you have a copy of Windows 3 or 95, you can try running under Virtualbox http://www.virtualbox.org/

  OpenOffice http://www.openoffice.org/ includes a database program.

  Otherwise, you can migrate your data to any Windows 7 compatible program. You left it too long as migration is not likely to be easy.

• 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.

• MS SQL relational databases

  I multilple of relational databases, our aspx developer was able to link them by using the stored procedure, but because I would like to convert the work in coldfusion, I found difficulties in the use of stored procedures to query all the relational databases, as the coldfusion connection it takes manually to each database. Here's the scenario:

  I have 5 databases MS SQL: [img1, img2, img3, img4 and descriptionDB]

  the "descriptionDB" contains the text and id identification information will be linked to a hexadecimal image in one of the databases [i] img images.

  How can I do a query using coldfusion to display the images and their texts related!

  You may be looking to fix something that isn't broken.  If stored procedures have worked in asp, there is no reason for them to not work in the CF.  The only link that you need is the db with the stored procedure.

• Design of the relational database when installing essbase version 11.1.1.3.0

  Hello
  My question is as below
  We intend to deploy essbase version 11.1.1.3.0 on platform Linux RHEL5. I want to know the design of relational database, we would need for shared service and EAS to configure and use according to the installation document.
  
  -At least the documentation mentions is 100 MB. Is this a possible size?
  -What happens when this 100 MB runs out? Will be this errror outside? It truncates and write again in system tables needed for shared services?
  -Lets say I have about 800 native users and since LDAP OPEN will disappear with this version as well so it will be written to the relational tables as well.
  
  -What would be a possible size in this case. Will be around 1 GB to 2 GB suffuce?
  Thank you
  Prasad

  I do not know what database you are using, but if it's Oracle, you can set the size to autoextend by a set for example size 50 MB.
  11.1.1.3 still uses Openldap, it is removed from 11.1.2

• Planning Workflow - metadata in the relational database

  Hello
  
  In the metadata in the relational database, there is only an ID for almost every column. I would like to have names for these IDs so I can understand more clearly what is happening. Mainly concerning the workflow, I like to check in the database, what happens.
  
  Is this possible?
  
  Thank you very much

  Hello

  Most of the IDS will link to the table of hsp_object

  So an example of discovering the name for the first two columns (plan_unit_id and scenario_id) in the hsp_planning_unit table

  Select puobj.object_name as 'PlaningUnitName', scenobj.object_name as 'Scénario' of
  pu plansamp.hsp_planning_unit, plansamp.hsp_object puobj, plansamp.hsp_object scenobj
  where pu.plan_unit_id = puobj.object_id
  and pu.scenario_id = scenobj.object_id

  You can extend it to include other columns such as version, entity...

  additional columns that don't point to hsp_object are

  last_column colum = 0 = promote; 1 = rejection; 2 = approve; 3 = approval; 4 = start; 5 = exclude
  process_state = 0 is not started.; 1 = first pass; 2 = under review; 3 = approved; 4 = closed; 5 = unsigned out

  Ok?

• 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).
