  You will have to grant execute DBMS_PIPE to the connection owner
  Or any login that uses the DBMS_PIPE

  Connect as SYS and run the following:

  GRANT EXECUTE ON DBMS_PIPE TO ;

• Procedure runs package Help

  Hello
  
  I need to get familiar with the procedures and packages if I put in place the code below in a procedure to run a package, when to use the DBMS_OUTPUT procedure. Put_line to display that returns the package.

• ORA-04067: not executed, the package body 'SCOTT. DBMS_PIPE' does not exist

  Hello world

  My version of DB is

  BANNER

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

  Oracle Database 11 g Enterprise Edition Release 11.2.0.1.0 - 64 bit Production

  PL/SQL Release 11.2.0.1.0 - Production

  CORE 11.2.0.1.0 Production

  AMT for 64-bit Windows: Version 11.2.0.1.0 - Production

  NLSRTL Version 11.2.0.1.0 - Production

  I ran this command SYS and SCOTT as well. But I can't see the body of DBMS_PIPE package. So, how can I test DBMS_PIPE then? Please help, suggest something here.

  @C:\app\BS\product\11.2.0\dbhome_1\RDBMS\ADMIN\dbmspipe.sql

  Kind regards

  BS2012.

  Have you had a look at the script of dbmspipe.sql?   Why not?  After all, it's just an ASCII text file.

  In any case the script is EXECUTED on the package to a role, execute_catalog_role.  So only users who have gotten this role will be able to use the DBMS_PIPE of the judgment.  You must login as SYS and grant EXECUTE to your username (do not grant them this role).  Oracle made this way because the pipes can be voracious consumers of system resources.

  Oh and drop the package from the SCOTT schema.  It's just a recipe for confusion.

  Cheers, APC

• Multi-threading parallel processing of stored procedures

  Hi guys,.
  
  I have the following scenario, and I would like to realize parallel processing to increase the performance of data refresh:
  
  Stored procedure "SP1" - refresh table A
  Stored procedure 'SP2' - Update table B
  Stored procedure "SP3" - updates table C
  
  I would like to be able to update table A, B and C table at the same time, could someone help me identify ways in what could be achieved if something like this is possible?
  
  I use collections in stored procedures SP1, SP2 and SP3 to accelerate the time to refresh table, although would like to know how parallel update tables.
  
  I have briefly heard the dbms_pipe package, which would be useful in this scenario?
  
  Thank you
  Rohan

  As already mentioned - perform these distinct process procedures in planning jobs. DBMS_JOB and DBMS_SCHEDULER interfaces can be used. If the work queue manager supports (has been configured) with 3 or more processes working slots and these are empty and not used, then all the 3 procedures can be performed in parallel.

  This can be as simple as running the following anonymous block to schedule 3 jobs for immediate execution:

  declare
    jobID number;
  begin
    DBMS_JOB.Submit( jobID, 'procA;', sysdate );
    DBMS_JOB.Submit( jobID, 'procB;', sysdate );
    DBMS_JOB.Submit( jobID, 'procC;', sysdate );
    commit;
  end;
  

  I have briefly heard the dbms_pipe package, which would be useful in this scenario?

  Only when the IPC (Inter Process Communication) is required only if the database pipes best fits this requirement.

• Run time output of DBMS_OUTPUT. PUT_LINE

  I would like to know why DBMS_OUTPUT. Put_line output gives only after the end of the execution of the procedure. I wonder why Oracle has not provided a package for the output of the run time.

  user10566312 wrote:

  It's because of the client server architecture.

  SQL and PL/SQL processes run on the database server.
  The database server has no access to clients, or screen keyboard, so cannot accept entries to the client keyboard, or write the output to the screen of the client.
  When the client software issues a statement to the database, it uses something like for example of SQL * more to establish a connection to the database, submit this request to the database and then waits for the request to complete, eventually return some results from that (e.g. the results of a SQL query).
  DBMS_OUTPUT does not write to any screen... it puts just the data that you specify in the DBMS_OUTPUT buffer. It is then up to the client software to request the contents of this buffer, but the client software cannot do that when the request he made was finished (only a single statement between client and server can be converted at any time). That's why you issue your request so the output once the query is complete.

  Oracle provides a way for you to run output at the time, if you want to start doing things with the DBMS_PIPE package, etc., although for the follow-up of the execution, I have a package that writes my 'output' to a table on the database by using an autonomous transaction and then the content of this table can be viewed from a second session While the first session is still being requested process. Similarly, you may have your 'exit', writes to a file on the database server using something like UTL_FILE and then you would be able to view the contents of this file running, as long as you open and close the file and make sure file buffers have been empty etc.

  DBMS_OUTPUT is not the tool to use if you want to display the output of the run time. It's not a fault of Oracle, it's just your lack of understanding of what tools do this work. ;)

• Tips to increase performance of recovery?

  Hello
  
  I do a few select odp.net against my oracle database queries.
  
  first of all I may do: select id,... from table1 where id in some_collection.
  then I can do select id from table2 where id in some_collection and id2 in some_other_collection etc.
  
  Let's say I do 3 to 5 odp.net with a few collections calls to retrieve a set of results from different tables. So my settings are in collections. Some of these collections are used in many of my calls.
  
  Now I'm doing calls with SqlCommand.CommandTYpe = CommandType.Text;
  Is there a difference between a text query and the other to a pl/sql stored procedure? I thought that maybe it would be good to remove switches context between the engine sql and pl/sql.
  
  In addition, if you use a stored procedure I guess I should use a REF CURSOR to retrieve data. What are the advantages and disadvantages of which compares to a normal text sql statement?
  
  If I use a ref cursor in a stored procedure that I can get also all calls directly via several ref Cursor, reducing the amount of calls and again by using the parameter in collections that are used by multiple queries. Want to just a few comments on the approach to take.

  Hello
  I did no performance test between raw SQL and PL/SQL to SQL via a change of context - but a quick glance at this link:
  http://asktom.Oracle.com/pls/asktom/f?p=100:11:0:P11_QUESTION_ID:60122715103602
  «But don't not afraid at all to call SQL PLSQL - it's what makes better PLSQL.»
  I think that the main time, that you will encounter the problem of context switch is when you call a function in an SQL statement (for example SELECT d.ColA, SomeFunctionHere (d.ColB) to d etc.)
  or when you have a loop in a PL/SQL that 1000 of inserts or updates rather than manage, in a single call.

  (dating back to asktom: http://asktom.oracle.com/pls/asktom/f?p=100:11:0:::P11_QUESTION_ID:47458244605081--> his mantra is repeated often in these forums)

  Now on packages, I'm a big fan of packets (so much so I tend to try actively don't put raw SQL (set or not) in my code). This is a personal preference thing, but I found that packages I would reduce my calls, are easier to maintain my SQL logic and data into autonomous units of nice, and I used PL/SQL more, I like to use (even in SQL Server, I tend to store proc everything!).

  REF Cursor: http://www.oracle.com/technology/pub/articles/mastering_dotnet_oracle/williams_refcursors.html
  Once again I did no stable performance between REF CURSOR and run the SQL in code (as I said I am biased towards using PL/SQL, whenever I can call a procedure/package and performance 2-5 ref Cursor in a single call, so I'm happy).

  Now you can return your result sets the UDT; they are a little more complex to work with and require:
  (1) a user defined type in Oracle
  (2) for a package that complete and mail it
  (3) based on Oracle on the side of .net code (they may automatically generate your classes, but you can still change classes if necessary)
  When you install ODP if you look in your ORAHOME\product\11.1.0\client_1\odp.net\samples\2.x\UDT, you will see some examples of work that.

  and a nice walk through via oracle: http://www.oracle.com/technology/obe/hol08/dotnet/udt/udt_otn.htm

  Now, I did tests with the UDT vs REF CURSOR performance, and as result sets get bigger the UDT becomes more effective for the insertion of the collections as opposed to a loop through to insert rows (this is of course with the exception of bulk insertions and others).

  I would say that your test scenario resembles a simple trying to packages with. I recommend trying to create a single call to get back all your data sets. Don't forget to create your package as your .net code, keep the small procedures/functions, so you can keep them in the future!

  "How a package help me? You're right, it's just a class in Oracle that can expose methods to use. These methods can be public or private, have full access to the features of Oracle for data processing, etc. I find it helps me maintain my component to the application database and bugfixes from time to time do really well without the expense of a MSI roll (our configuration has db changes a little bit easier to realize that changes server .net)

  I recommend to try to reduce your number of requests as much as possible (exploring the joints) and try to have done with a single command and return the data more quickly and easily as possible. The UDT can be a good thing to play with, but I would seriously look at and make sure that it fits in your directions for development of the Department and you think it will be easier to maintain. We slowly put our toes in the waters of the UDT and mainly use a ref CURSOR returned by packets.

• !!!! NEED HELP URGENT! Cannot / uninstall ArcGIS Desktop: "error 1721. There is a problem with this Windows Installer package. A program required for this install to complete could not be run. Contact your support personal or package.

  I use a 2005 Dell Precision 670 with OS Microsoft XP Professional x 64 Edition Version 2003, Service Pack 2.

  I tried to update my version of ESRI ArcGIS Desktop v9.3 to v9.2, but in the process of uninstalling v9.2 there error/corruption (although at the time, I don't remember getting the error messages).

  Symptoms were: program icon not slot "start > programs" or less "C; "" / Program Files "C:/Program Files (x 86) or ' but the icon still appeared in the list of installed programs in"Add or remove programs ".

  Suggestions to be by ESRI:

  -Re-registration of the service Windows Installer - Ran fine, but the error still there.

  -File system - fine Ran but error checker always run here.

  -Downloaded Windows Installer cleanup - NO error found.

  -Downloaded CCleaner - NO error found.

  -Manually deleted the program, manually remove the following program files: C:\program files\arcgis; C:\Program Files\Fichiers files\esri. C:\Documents and setting\%user name%\application data\ESRI

  -Manually remove ESRI records in the registry: I did it by start > run REGEDIT [press ENTER], then navigate hkey_local_mahine/software and sailed to hkey_current_user/software.

  -Tried to repair the program from the installation disc, but it always seems to grind to a hault about 50-75% through the configuration of the repair procedure.

  -Tried to uninstall the program with the vision more recent ArcGIS Desktop but I still get the ERROR 1721.

  I was once in contact with the package vendor (ESRI) UK support team and they sent this problem at their headquarters in the States.

  I'm really at a lost as to how this can be fixed, because this program is what I use for my career! Help, please!

  This may be a day late and a dollar short, but there is a question we've seen recently with ArcGIS facilities.  There is a registry change to ArcGIS that limits the size of the regestry and NOTHING prevents installation once this limit is reached.

  Do the following reg key change:

  HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\RegistrySizeLimit

  Update the value ffffffff

  Restart the computer.
