Run the PL/SQL procedure periodically

Hello everyone.

Im working with Oracle 10 G R1.

I need execute a PL/SQL procedure every 5 minutes.

Can anyone send me an example or a link where I can study how to proceed?

Thanks in advance and greetings to all.

Hello

From the point of view Os you use crontab - to run a script
Refer to:

Re: "insufficient privileges" error when you run the Java stored procedure in another schema

I get an "insufficient privileges" error when you run the Java stored procedure in another schema, see details below. I don't know what are missing privileges (I already granted the EXECUTE privilege), suggestions? -Thank you.
Define a simple java class and deploy it as a Java stored procedure to test:

Schema: User1
test of the package;
public class HelloWorld {}
public HelloWorld() {
Super();
}
public static String Hello () {}
Return "HELLO";
}
}
CREATE or REPLACE FUNCTION HELLO RETURN VARCHAR2 AUTHID CURRENT_USER AS LANGUAGE JAVA NAME ' test. HelloWorld.hello () return java.lang.String';
Grant execute on USER2 HELLO
Test the Java stored procedure through the PL/SQL function call (in the same schema):

Schema: User1
SET SERVEROUTPUT ON
DECLARE
v_Return VARCHAR2 (200);
BEGIN
v_Return: = User1. HELLO;
DBMS_OUTPUT. Put_line ('v_Return =' | v_Return);
END;
anonymous block filled
v_Return = HELLO
Test the Java stored procedure through the PL/SQL function call in a different pattern:

Schema: USER2
SET SERVEROUTPUT ON
DECLARE
v_Return VARCHAR2 (200);
BEGIN
v_Return: = User1. HELLO;
DBMS_OUTPUT. Put_line ('v_Return =' | v_Return);
END;
Error report-
ORA-01031: insufficient privileges
ORA-06512: at "User1." HELLO', line 1
ORA-06512: at line 4 level
01031 00000 - "insufficient privileges".
* Cause: An attempt was made to change the user name or password
without the privilege appropriate. This error also occurs if
trying to install a database without the need for employment
access privileges.
When Trusted Oracle is configure in DBMS MAC, this error may occur
If the user has been granted the privilege necessary for a higher label
that the connection is active.
* Action: Ask the database to perform the operation or grant administrator
the required privileges.
For users Trusted Oracle get this error, well that granted the
the privilege that is suitable for the top label, ask the database
administrator to grant the privilege to the appropriate label.

You have created the function with AUTHID CURRENT_USER, which means that the function is executed with the rights of the applicant (but not with the rights of the author). This means that the applicant must have grants (directly or through roles) on all used/accessible objects in the service. In your case the user USER2 has not granted with EXECUTE on the class/source Java test. Class HelloWorld, causing the ORA-01031 exception. You create service without AUTHID CURRENT_USER (i.e. with AUTHID DEFINE, which is by default, if you do not have a specific reason to use AUTHID CURRENT_USER) or grant EXECUTE on JAVA test SOURCE. Class HelloWorld to User2.

Complete script.

I had been struggling with the same problem for 2 days. You run the script as sysdba, how do you get the error then insufficient? I did my first test GG in February. I've been on 11.2.0.3 + patch January + patch for the integrated capture. It has worked well for me. I went back to my GG test week with 11.2.0.3 + patch of July last and ran into the same problem. The solution for me was the last version of GG. See my previous post for the patch numbers.

Call the PL/SQL procedure with in out parameter of OIC clob
Hello

For a few days, I am facing a problem. I have to call the pl/sql procedure with colb parameter out. I use c ++ and OIC (don't ask me why :)).

I use a pl/sql problem test procedure:

create or replace function Test (longField outside clob) return number is
Number of result;
Start
longField: = 'prefix ';
Result: = 12;
Return (result);
end Test;

So I do all the stuff with the connection to the DB,

I prepare the statement: "start: res: = test(:param); end; »
So I OCIHandleAlloc (m_pCtx-> hpEnv,
(void *) & m_hpStatement,.
OCI_HTYPE_STMT,
0,
(NULL);
and
OCIStmtPrepare (m_hpStatement,
m_pCtx-> hpErr,
(...),
(...),
OCI_NTV_SYNTAX,
OCI_DEFAULT);

Before the binding I prepare parameters. For a clob I devote to the lob Locator:

OCIDescriptorAlloc ((dvoid *) m_pCtx-> hpEnv, (dvoid *) & m_pLobLocator,)
(ub4) OCI_DTYPE_LOB (size_t) 0, (dvoid *) 0);
OCILobEnableBuffering (m_pCtx-> hpContext, m_pCtx-> hpErr, (OCILobLocator *) m_pLobLocator);

that I bind parameters using OCIBindByName and OCIStmtExecute statement execution.

I get an error
---------------------------
Microsoft Visual C++
---------------------------
Unhandled exception in... (ORAOCIEI11. (DLL): 0xC0000005: Access Violation.

My question is: is it possible to call the pl/sql procedure with parameter BEAK clob?
If Yes, what steps I need to do to succeed?

Thank you for your response.
Hello

Of course, it is possible :)

Show that you are your piece of code that is binding.
Are you sure you had correctly the lob descriptor in the call to bind?

Cannot create Materialized View using the PL/SQL procedure

Hello

I have a question related to the creation of materialized view.
I have a stored procedure that creates the materialized view. When you try to perform this procedure, I get not enough privileges error: ORA-01031.

When I run the content of this procedure as a PL/SQL block anonymous their materialized view is created without any complications.
Can you please advice me on this subject?
It is even possible to create a materialized view in the stored procedure as I found no info on this subject.

Thank you
Petr

Hi chudapet,

Whenever you make in procedure, you must have direct subsidies and not through a role.

Most likely the grant to create a materialized view is available via a role to your username.
Assign a direct grant to the user:

grant create materialized view to scott;
{code}

Problem to run the shell script procedure

Hello

I wrote a shell script which needs to execute the stored procedure

The shell script:

cat bi_loading2.sh
#!/usr/bin/ksh
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=/u01/app/oracle/product/11.2.0/DWH11gR2
export ORACLE_SID=DWH
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME/lib
echo "zero  arg  is  :$0"
echo "First arg  is  :$1"
echo "Second arg is  :$2"


/u01/app/oracle/product/11.2.0/DWH11gR2/bin/sqlplus  system/xxx@dwh << EOF
insert into SYSTEM.POC_EXDATA_RESULTS  values($1,'$2',sysdate,null);
commit;


execute system.$2;
     
update SYSTEM.POC_EXDATA_RESULTS
set end_date=sysdate
where id= $1;

commit;
EOF
exit 0

The script gets two parameters: id (1) (2) the procedure that I have to run

As you can see below oracle is to omit the 'run' command
Please notice why I can't run the stored procedure.

$ 83 poc_cf54xbx6cchf2 bi_loading2.sh

zero  arg  is  :bi_loading2.sh
First arg  is  :83
Second arg is  :poc_cf54xbx6cchf2

Thread safe operations on the table in the pl/sql procedure?
I develop java application that will run in N locations simultaneously, each application will be of the sons of Mr. each thread takes a unique ID with the NOT_TAKEN State of the queue table and changes its status to TAKEN.
Problem:
How to prevent situation like this thread:
1 get a first select ID with NOT_TAKEN status
2. at the same time thread B select first (so it will be the same ID chosen thread A) ID have the status of NOT_TAKEN.
3 put on a status of changes of identity and
4 thread B status of the TAKEN ID changes
After this thread A and B using the same ID.

What I did:
I've written pl/sql procedure that queue table in exclusive mode lock, selects the first ID, changes its status to CATCH and unlocks the table. Because it is lock in exclusive mode for a single thread can run this procedure at the same time.

Question:
Optimal how must it be resolved, because mine solution prevents to perform all the other updates on the queue table, while it is locked, as the change in status of OPERATION_DONE TAKEN so there performance problem.
As Centinul said, you need to lock just one line.
I would just add NOWAIT to the select statement to let the Java thread go and try again, rather than wait for other threads.
Example: (not tested)
```
--
-- Assuming structure of your QueueTable: ( IDCol is PK , StatusCol is VARCHAR2, ... )
--
--
-- or make it part of the package....
CREATE OF REPLACE
FUNCTION updateQueue( nQID QueueTable.IDCol%TYPE) RETURN VARCHAR2 AS
   eLocked EXCEPTION;
   PRAGMA EXCEPTION_INIT(eLocked,-54);
   CURSOR curQueueTable IS SELECT 1 CNTR FROM QueueTable WHERE IDCol=nQID AND StatusCol='NOT_TAKEN' FOR UPDATE OF StatusCol NOWAIT;
   recQueueTable curQueueTable%ROWTYPE;
   cRtn VARCHAR2(1); 

BEGIN 

   cRtn := 'Y';
   BEGIN 

      OPEN curQueueTable;
      FETCH curBuffSummary INTO recQueueTable;
      CLOSE curQueueTable; 

      IF recQueueTable.CNTR IS NOT NULL AND recQueueTable.CNTR = 1 THEN
          UPDATE QueueTable SET StatusCol = 'TAKEN' WHERE IDCol=nQID;
      ELSE
          -- Already updated
          cRtn := 'N';
      END IF; 

         -- You can control your transaction here as well
         -- COMMIT;
         -- But if realy should be done in the Java thread. 

    EXCEPTION
       WHEN eLocked OR STANDARD.TIMEOUT_ON_RESOURCE THEN
       -- Thread could not get exclusice row lock. Ignore error.
         cRtn := 'N';
         NULL; 

      WHEN OTHERS THEN
         -- Handle other errors...
         -- NULL; just kidding...
         RAISE;
   END;
   RETURN cRtn; 

END;

Need to check delays in update of 1000 lines using the PL/SQL procedure.

Hi all
I'm new to PL/SQL. I need your help to build a procedure that executes the following statement and follows the time of update of 1000 rows. This is to check the performance of the database. I need to print the timestamp of start before the update and end timestamp after update. I need to do for the 1000 lines. The statement that will be used in the procedure is:
SELECT
'UPDATE XXAFL_MON_FACTS_F SET TASK_WID =' | NVL (TO_CHAR (TASK_WID), 'NULL') |', EXECUTION_PLAN_WID =' | NVL (TO_CHAR (EXECUTION_PLAN_WID), 'NULL').
', DETAILS_WID =' | NVL (TO_CHAR (DETAILS_WID), 'NULL') |', SOURCE_WID =' | NVL (TO_CHAR (SOURCE_WID), 'NULL') |', TARGET_WID = ' | NVL (TO_CHAR (TARGET_WID), 'NULL').

', READ_THRUPUT =' | NVL (TO_CHAR (READ_THRUPUT), 'NULL') |', LAST_UPD = ' | NVL (TO_CHAR (LAST_UPD), 'NULL') |', RUN_STEP_WID = "' | NVL (TO_CHAR (RUN_STEP_WID), 'NULL').
"', W_INSERT_DT = ' | NVL (TO_CHAR (W_INSERT_DT), 'NULL') |', W_UPDATE_DT = ' | NVL (TO_CHAR (W_UPDATE_DT), 'NULL').
', START_DATE_WID =' | NVL (TO_CHAR (START_DATE_WID), 'NULL') |', END_DATE_WID = ' | NVL (TO_CHAR (END_DATE_WID), 'NULL') |', START_TIME =' |
NVL (TO_CHAR (START_TIME), 'NULL') |', END_TIME =' | NVL (TO_CHAR (END_TIME), 'NULL'). "WHERE INTEGRATION_ID ="' | INTEGRATION_ID | " « ; » OF XXAFL_MON_FACTS_F;
The above query creates instructions of update that must be executed 1000 times and the time required to update the 1000 lines should be followed.
Thanks in advance!

Code horribly wrong!

Why this approach?

Dynamic SQL is almost NEVER needed in PL/SQL. And if you think it's necessary and taking into account what is displayed as being problems here, you have a 99% chance of being wrong.

This 1% where dynamic SQL is necessary, he will WITH bind variables to create shareable SQL, decrease memory requests, decrease the likelihood of a fragmented shared reel and decrease the burning CPU cycles on hard analysis.

An example below. Your approach is the 1st. One that is slower than the correct approach to 37 (x_!) ...

Nested reading XML using XQUERY in the PL/SQL procedure

I'm using Oracle 11 G.
I have a PL/SQL procedure, which is reading XML using xquery XMLTYPE column in a table. The XML contains data of the DEPARTMENT and its SECTIONS. DEPARTMENT has a to-many with SECTIONS or a DEPARTMENT can have one or more SECTIONS, and there may be cases where the DEPARTMENT will have all SECTIONS.

The XML structure is such that

<DATA>

label to identify a DEPARTMENT and all its corresponding SECTIONS.

ORA-19279: XPTY0004 - XQuery dynamic type mismatch: expected singleton 
sequence - got multi-item sequence

It is natural because I have several sections, now how I'll handle this situation.

It's the usual approach to manage several nested collections:

SQL> select d.department_id
  2       , d.department_name
  3       , s.sections_id
  4       , s.sections_name
  5  from offline_xml t
  6     , xmltable(
  7         '/ROWSET/DATA'
  8         passing t.xml_file
  9         columns
 10           DEPARTMENT_ID   varchar2(20) path 'DEPARTMENT/DEPARTMENT_ID'
 11         , DEPARTMENT_NAME varchar2(30) path 'DEPARTMENT/DEPARTMENT_NAME'
 12         , SECTIONS        xmltype      path 'SECTIONS'
 13       ) d
 14     , xmltable(
 15         '/SECTIONS'
 16         passing d.sections
 17         columns
 18           SECTIONS_ID     varchar2(20) path 'SECTIONS_ID'
 19         , SECTIONS_NAME   varchar2(30) path 'SECTIONS_NAME'
 20      ) s
 21  ;

DEPARTMENT_ID        DEPARTMENT_NAME                SECTIONS_ID          SECTIONS_NAME
-------------------- ------------------------------ -------------------- ------------------------------
DEP1                 myDEPARTMENT1                  6390135666643567     mySection1

The problem with ampersand in the PL/SQL procedure

Dear Oracle experts,

Please, help me to understand this case. I have the following code

V_RESPONSE := UTL_HTTP.GET_RESPONSE (V_REQUEST);

      LOOP
         UTL_HTTP.READ_LINE (V_RESPONSE, V_BUFFER, FALSE);
         DATA_OUT := DATA_OUT || V_BUFFER;
      --DBMS_OUTPUT.PUT_LINE (V_BUFFER);
      END LOOP;

And I'm getting DATA_OUT as

<?xml version='1.0' encoding='UTF-8'?><soapenv:Envelope xmlns:soapenv="http://www.w3.org/2003/05/soap-envelope"><soapenv:Body><ns:chargeSubscriberResponse xmlns:ns="http://ws.cube.az"><ns:return>&lt;?xml version="1.0" encoding="UTF-8"?>
&lt;response>
     &lt;retval>-2200003&lt;/retval>
     &lt;retmsg>Invalid Service&lt;/retmsg>
     &lt;quantity>&lt;/quantity>
     &lt;cube-transaction-id>&lt;/cube-transaction-id>
&lt;/response></ns:return></ns:chargeSubscriberResponse></soapenv:Body></soapenv:Envelope>

A don't have to '&' in this output. I need to analyze this variable to clear all ampersands. How can I do?

Just replace does not work... I tried

PROCEDURE Clean_up_xml (v_xml IN OUT VARCHAR2)
   IS
   BEGIN
      WHILE INSTR (v_xml, 'lt;') > 0
      LOOP
         v_xml :=
            SUBSTR (v_xml, 1, INSTR (v_xml, 'lt;') - 2)
            || SUBSTR (v_xml, INSTR (v_xml, 'lt;') + 4);
      END LOOP;
   END;

But no luck...

Does not erase the procedure '& '. How can I disable ampersand in PL/SQL procedure?

Thanks in advance.

PS: I know SET DEFINE OFF. But it only works in SQL * MORE.

How to call sql loader control file with in the pl/sql procedure
Hi friends,

I am doing a project in relation to the transfer data using queues. In the queue, I'll get a data delimited by tabs in the form of CLOB variable/message. I don't want to keep this dat in the oracle table.
During the updating of the data in the table.

1. don't want to write data to a file. (You want to access directly after the specific queue).

2. as the data is in the form of delimited by tabs, I want to use sql loader concept.

How can I call the ctrl charger sql file with in my pl/sql procedure. When I searched, most forums recommending the external procedure or a Java program.

Please guide me on this issue. My preferrence is pl sql, but don't know the external procedure. If no other way, I'll try Java.

I'm using oracle 9.2.0.8.0.

Thanks in advance,
Vimal...
Or SQL * Loader, or external tables are designed to read data from a CLOB stored in the database. They both work on files stored on the file system. If you don't want the data to be written to a file, you have to roll your own parsing code. It is certainly possible. But it will be much less effective than SQL * Loader or external tables. And it is likely to lead to a little more code.

The simplest possible thing that might work would be to use something like Tom Kyte string tokenization package to read a line in the CLOB, divide the component parts and save the different chips in a significant collection (i.e. an object type or a record type that matches the table definition). Of course, you need manage things like the conversion of strings to numbers or dates, rejecting the lines, writing to log files, etc.

Call the PL/SQL procedure with different parameters?
I use PL/SQL for web development. I have a page of PL/SQL which collects information and returns the user off site with one return url (another PL/SQL procedure).

I have the return procedure with every documented return variable (default null) in order to always take the return. However, there are (reported... cannot reproduce because of the nature of the business) cases where a 404 error is returned because of the incompatibility of parameter.

Is it possible to proceed regardless of the parameters? Someone at - it suggestions?

Thank you!

Use the interface "+ flexible +" mod_plsql - see the Oracle® HTTP Server mod_plsql user's Guide for the documented details.

The signature of the procedure parameter is as follows (it is called by mod_plsql using tables of name value pairs):
```
create or replace procedure Scott.MyWebProc( name_array owa.vc_arr, value_array owa.vc_arr) is
...
```
In your code, you just browse the berries to get the name values passed query string. You can even filled an associative array in your code (a table indexed by string and no number, where the index string represents the name of param)-this approach can make it pretty easy for the code make reference to a parameter, with little effort on your part to provide an interface to query by name for code to get the value of a parameter name.

To enable the flexible (aka parameter 2) call interface, precede the call to web with an exclamation character. For example
```
http://my-webserbver.my-domain.com/pls/dad/!scott.mywebproc?name-1=val-1&name-2=val-2..,name-n=val=n

Run the second sql statement only if the first sql statement is set to zero.
Hey guys I seem to have a mental block here. I have two sql statements. I would like to than the second to run only if the first sql statement is set to zero. I know that I can use PLsql but I would really like to see if I can do this with sql upward. Your answers are very much appreciated.
This is the first sql
```
  Select     ft.fund_code, 
             ft.orgn_code, 
             ft.acct_code, 
             ft.amount, 
             fb.owner_pidm, 
             ft.prog_code      
      from ftrbremb fb , ftcractg ft
      where fb.doc_code = 'TR000038'
      and fb.ftpbport_id = ft.ftpbport_id
```
second sql statement
```
     Select ft.fund_code, 
             ft.orgn_code, 
             ft.acct_code, 
             ft.amount, 
             fb.owner_pidm, 
             ft.prog_code      
      from ftrbremb fb , ftcractg ft, ftprexps fx
      where fb.doc_code = 'TR000038'
      --and fb.ftpbport_id = ft.ftpbport_id
      and fx.ftrbremb_id = fb.id
      and ft.ftprexps_id = fx.id;
```
How can I combine these two statements together so that when the first is null the second run. As a bonus, I want to get just the first line as well.
Any help would be greatly appreciated. I tried to accomplish with the case statement but it dosent everything seems to work for me.
Thank you
Miguel,

the idea is simple: join the two queries (via the union of all) and to change the second part as to return only the rows if the first query returns no rows by changing the NOT EXISTS (first request). Hope I made it clear... ;)

Run the custom login procedure
I use authentication APEX to allow users in the enterprise application. I would like to hitch on the authentication mechanism and essentially write an audit record which shows that connected when, on demand. What is the best way to do it?

The other issue is that I have to do the same thing when a user disconnects in... What we want to do is try to build some sort of card for some clerical users that triggers these events based.
Edit the nav bar item, disconnection and under target, set the target on the page Type and enter the page that contains your audit logout with redirection procedure to the logout url - in this way they will be directed to your "Logout" page but as soon as they get there, the logout process is run and the header then redirects them to the real disconnection procedure who does the logout and sends them to the login page.
