• How to use the API of PL/SQL DBFS

  Hi guys,.
  
  I re-post this question to see if someone can help out me. I'm trying to use the API of PL/SQL DBFS to manipulate the files stored in DBFS.
  
  Details of the environment:
  Windows 7 or 5.5 OEL (I tried both platforms)
  Database: Oracle DB EE 11.2.0.2
  IDE: SQLDeveloper on Windows 7
  
  I have two users, DBFS_USER, who is the shop owner DBFS and MYUSER that connects to the store to manipulate files using the API of PL/SQL DBFS.
  
  Creation scripts:
  -----------------
  Connect / as sysdba;
  
  Dbfs_ts CREATE TABLESPACE DATAFILE 'D:\oracle\oradata\orcl\dbfs01.dbf' SIZE 1 M AUTOEXTEND ON NEXT 1 M;
  
  -create users
  create dbfs_user user identified by dbfs_user quota default tablespace unlimited dbfs_ts on dbfs_ts;
  create myuser identified by myuser;
  
  -grant the role
  GRANT RESOURCES, CREATE VIEW, CREATE SESSION, DBFS_ROLE, CREATE TABLE TO dbfs_user.
  GRANT RESOURCES, CREATE VIEW, CREATE SESSION, DBFS_ROLE, CREATE TABLE TO myuser.
  
  -create a filesystem (such as DBFS_USER)
  connect dbfs_user/dbfs_user;
  
  exec dbms_dbfs_sfs.createFilesystem ('STAGING_AREA_FS');
  
  exec dbms_dbfs_content.registerStore ('STAGING_AREA_FS', 'posix', 'DBMS_DBFS_SFS');
  
  dbms_dbfs_content.mountStore exec ('STAGING_AREA_FS', 'staging_area');
  
  commit;
  
  -export store STAGING_AREA_FS (as DBFS_USER)
  
  exec dbms_dbfs_sfs.exportFilesystem ('STAGING_AREA_FS');
  
  -Check the names of table (like MYUSER)
  connect myuser/myuser;
  
  -He can't see (without brackets)
  Select * from table (dbms_dbfs_content.listMounts);
  
  -Note at the bottom of the table table_name
  Select * from table (dbms_dbfs_sfs.listTables);
  
  -Mount as MYUSER (example with SFS table_name $ _FST_32)
  dbms_dbfs_sfs.registerFilesystem exec ('MYUSER_FS', 'DBFS_USER', ' FS$ _FST_32');
  
  exec dbms_dbfs_content.registerStore ('MYUSER_FS', 'posix', 'DBMS_DBFS_SFS');
  
  dbms_dbfs_content.mountStore exec ('MYUSER_FS', 'staging_area');
  
  commit;
  
  -verification of Mount (like MYUSER)
  
  Select * from table (dbms_dbfs_content.listMounts);
  
  Select the path in dbfs_content;
  
  
  CREATE a STORED PROC (like MYUSER)
  ----------------------------
  
  CREATE OR REPLACE PACKAGE MYUSER_PKG
  
  CreateDirectory function
  (P_File_Path IN VARCHAR2,
  P_ErrMsg OUT VARCHAR2)
  return number;

  l_Return: = NVL (SQLCODE,-1);
  P_ErrMsg: = SQLERRM;
  RETURN l_Return;
  CreateDirectory END;
  
  END MYUSER_PKG;

  When you compile the package, I get this error:
  Error (9,11): PLS-00201: identifier 'DBMS_DBFS_CONTENT' must be declared

  How can I solve the problem in the error message? I'm not an expert in DB. I used this reference documentation: http://download.oracle.com/docs/cd/E11882_01/appdev.112/e18294/adlob_client.htm#CIHDEJAA

• How to use the two counters to PXI-6280, to read and write at the same time?

  Hi all

  I try to use PXI-6280 counter to generate a command of step motor pulse train.  The idea is to send a number done and known pulse for the engine, which belongs to a system XYZ. The point is, if, at some point, the user or the security system can interrupt the movement. If this happens (and will be... a lot), I will lose the real position, because I don't know how many pulses were actually sent to the engine. That is why I want to use the other cost to count impulses how were actually sent to the engine. I can start any tasks (generating or account), but only the first started task will operate. I met a couple of mistakes and I'm not able to find a solution.

  Is it really possible to use the two counters? I've already done this in a pci system and worked without problems.

  Thanks in advance,

  Giavonna

  Electrical engineer

  I'm afraid that I don't understand your idea. Could explain you better?

  Material of the series M support pointing to an arbitrary digital signals at rates (the clock must be provided from another source, for example a counter).  If you want a digital pulse train finished output and have access to a counter (the two counters if find you another source for your clock, for example the subsystem "output frequency"), you must use this subsystem 'digital output' rather than the output of the counter.  There should be examples in the finder of the example shows how to configure a finished task of digital output.

  Now I'm generating sample clock having a single Timed material Point (the only mode accepts this mode), and configure the counter with finite samples.

  I don't think not just single point NI the hardware, that's what you want.  More commonly, output meter tasks use timing 'Implied', where the release date is implicitly determined by the characteristics of the pulse user-defined.

  Is there a way to stop the production of only one meter when a finite number of pulses has been played in another counter?

  Yes, but it's a little tricky.  You can set a trigger 'Pause' on the output task, with the soruce the break being the internal release of the counter used for the task of entry.  Set the initial value of the counter of entry to 2 ^ 32-N (or maybe 2 ^ 32-1-N, I don't have a system right now to check) where N is the desired number of pulse output.  Together the counter event behavior for the counter edges of County switch output (this is a property of DAQmx export Signal).  When the counter of entry reaches terminal, its in-house production switches, causing thus the task of output to pause.  You can then stop the task in the software (you should be able to use the output of the task of entry counter event to signal to the software when the output is paused).

  Now that I've written that the whole paragraph, I remember something * similar * to work around a limitation of the driver here .  It is not quite the same implementation I described above, but really, you can use a meter output or a counter entry to get the same effect (it could be a good place to start anyway if you want to try this).

  Is there a way to read pulses them how have been generated, without the other counter, counting impulses?

• How to customize the default behavior of Excel to Oracle reports

  We are generating an Excel report using report Builder10g.
  Loan_No. column is of type varchar, but the client has only numbers in there that is longer than 15 characters sometimes like (121231231123124324).
  The values in this column appear as 'Exponential' by 'E' Excel thinks that this value is digital (123213E).
  For the test, I add a Word to say of the character 'A' and a comma before this Loan_No as (A121231231123124324) /('121231231123124324'), then the Excel shows this fine Loan_No if she sees this as a tank.
  The other option customer request to manually change the column Loan_No in tank in Excel, once the report is generated.
  
  My question to this forum is... can we change the default behavior of Excel Report Builder... ?
  In other words, can we create an Excel Macros and add it to our code... while creating an Excel report?

  Please let me know how to do this.

  Kind regards

  Mahdi Bellavia

  I have a G5 DL385 (AMD of the DL380 version) with a DLT3.   I use an Adaptec 29320LPE, appearing on the compatibility list.  We plugged a HP Ultrium 920 changer using the 'old method' SCSI passthrough.  We bought the Adaptec card, because we used initially ESX3.5.  We are now on ESX4.0, but for various reasons, the configuration left the same, so I have not tried with VMDirectPath I don't know if it is possible to use the SC11ex card, but if you arrive VMDirectPath at work, it seems then you need another SCSI card.

  Please see the documentation.  Windows 10 is not a certified platform.  The installation program performs a check to determine if the platform you are installing on is acceptable.  Probably, he sees that you're on Win10 and exits.

  Reminder, the basic steps to install are the following (don't forget first install Windows loopback adapter if the machine doesn't have a static IP):

  1. install the JDK 8U51 + (x 64)

  2. install WLS Infrastructure 12.2.1

  3. install the forms/States 12.2.1

  4. run the repository creation utility (RCU)

  5. run the Setup Wizard (to create the domain)

  6. start the WLS Node Manager, Server Admin and WLS_FORM.  If Windows, you must use a DOS shell with administrator privileges to do this commissioning initial.  Otherwise will result in the field not be created properly.

• How to use the Group condition in the ODI mappings

  Hi Experts,

  I have a requirement in the customization of BI applications. Can you please someone explain how to use the LISTAGG function in odi mapping.

  I applied the LISTAGGR function at the level of mapping odi, but I get error below.

  Mapping of ODI: ColumnName: ENAME Expression: LISTAGG (EMP. ENAME, ",") THE GROUP (RANKING BY EMP. ENAME)

  Error:

  ODI-1240: Flow LIST_AGG_FUN_USAGE fails during an operation of integration. This flow of charge table target EMP_BI.

  ODI-1228: task failed LIST_AGG_FUN_USAGE (integration) on the scott_db of ORACLE target connection.

  Caused by: java.sql.SQLSyntaxErrorException: ORA-00937: not a function of simple-group

  
  

  Oracle query:
  

  If I used this sql query in the database the correct result is.

  SELECT DEPTNO, LISTAGG (ENAME, ',') WITHIN THE EMP EMP (ENAME CONTROL) GROUP. DEPTNO;

  Output:

  10	CLARK, KING, MILLER
  20	ADAMS, FORD, JONES, SCOTT, SMITH
  30	ALLEN, JAMES, MARTIN, BLAKE, TURNER, WARD

  
  

  Please give your valid solutions, thanks in advance.

  Kind regards

  REDA

  If you try in #ODI12C then in the set of properties, you can select the column which should be used to group by.

  If it's 11g so its bit complicated. Simply replace the mapping with below codes.

  LISTAGG (EMP. ENAME, ",") WITHIN GROUP (ORDER BY ENAME) / * sum() * /.

  Magic!

• How to use the global variable in the table target?

  Hello

  I am trying to load several files into a single interface. the data is loaded successfully. 92. the files are there. for this I used variables and package.

  My requrement is 92 files of data loaded into the target table. I want to know what data from file.

  to this I added a column (filename) to the existing target table.

  If I used joints (not same condition), its totally wrong. all file names are coming.

  Please see the following screenshots.

  

  exit; target table.

  

  in fact in the target table. first 10 lines are coming from file.i.e first _ACCOUNT_LIMIT_511.TXT. but all the files names are coming.

  I'm confuse. After the first data file inserted then insert second data file. in that all file names are coming. Please help me.

  I thought that the global variable is preferable to identify the data came from which file.

  to do this, the global variable is used in the target table. I don't always have my exit.

  Please help me.

  Thanks in advance.

  

  Hello

  You can use the same way, how you use the project variable, just you have to do a thin is #GLOBAL.variable_name for example: #GLOBAL. SMART_AL_FILE_NAME_S

  Note: Make sure you that while you use one variable overall in interface, indicator should be staged as you chose above the screen

  hope this helps you

  Kind regards
