Execute Java Program From Oracle Procedure Which Is On Different Machines
Oct 10, 2012
Machine 1: Oracle server installed and database hosted on this Machine.
Machine 2: Oracle client is installed and connect through sqlplus to database in machine 1.
The requirement is: I need to have a Java/C program in machine 2 (where client available) which needs to be called from the stored procedure in server on machine 1. The objective is calling a java/C program from Oracle stored procedure but available on 2 different machines. Is it possible,
I've created a Java class in my Oracle DB that calls a Visual Basic program to convert a XLS file into a CSV file in order to load it into an external table. The problem that I have is that when I call the Visual Basic program from the Java class, nothing happens. I had the same problem with a Python program, and I thought that the problem was from Python, but now with Visual Basic the problem remains, both aren't executed.
The strange thing is that when I call the same Java class outside Oracle, directly from a command line, it executes both Python and Visual Basic programs.
Here is the Java class defined in Oracle:
CREATE OR REPLACE AND COMPILE JAVA SOURCE NAMED "OSCommand" AS import java.io.*; public class OSCommand{ public static void Run(){ try {
[code]....
And here is the procedure that calls the Java class:
create or replace procedure run_os_command as language java name 'OSCommand.Run()';
We have a daily batch job executing a oracle-plsql function. Actually the quartz scheduler invokes a java program which makes a call to the oracle-plsql function. This oracle plsql function deletes data (which is more than 6 months) from 4 tables and then commits the transaction.
This batch job was running successfully in the test environment but started failing when new data was dumped to the tables which happened 2 weeks ago (The code is supposed to go into production this week). Earlier the number of rows in each table was not more than 0.1 million. But now it is 1 million in 3 tables and 2.4 million in the other table.
After running for 3 hours, we are getting a error in java (written in the log file) "...Connection reset; nested exception is java.sql.SQLException: Io exception: Connection reset....". When the row-counts on the tables were checked, it was clear that no record was deleted from any of the tables.
Is it possible in oracle database, for the plsql procedure/function to be automatically terminated/killed when the connection is timed out and the invoking session is no longer active?
I am writing a java stored procedure in my package. In the java procedure I want to issue a query to be fired on the user table from which I am calling the java procedure.
Some thing like following:
I am logged in to USER1 and my package is inside USER1. From this package I am calling the Java Stored Procedure. In java procedure I want to make a jdbc connection to USER2. The details of USER2(password, hostname,portno) are stored in a table called 'connection_details' and this table is in the USER1.
My problem is how can I issue the
SELECT details FROM CONNECTION_DETAILS for USER2
so that i can get the details..?
Do i need to first make jdbc connection to USER1 and then execute the above query for which i need similar details of USER1. How can i obtain the details of USER1 here.
I am thinking if I am already in USER1 then do I need to make the jdbc connection to USER1 and then execute the query?
In my Organization I am trying to install oracle ODTwithODAC112030 but one Error showing that is java virtual machine could not find main class program will Exit.

i`m trying to use pl/sql function to execute java class. I created 2 tables with around 100 values and java class with simple functionality. I need to create function to loop through my table1 and get with each iteration one value from table and pass that value as parameter to java class.
table1 is something like this:
ID NAME 1 name1 2 name2 3 name3 . . . . 100 name100
table2 is empty with same columns as table1 ( table2 is for data obtained from java returns ) I created in sql+ java class.
CREATE OR REPLACE AND RESOLVE JAVA SOURCE NAMED "myClass" AS import java.io.*; import java.util.* public class myClass { public static String fun(String strName)
[code]....
Then i wanna make a pl/sql function for:
1)For i = 1 Obtain first value from table1 (column name) and pass it throught java class then return value and save it in table2 with the same id as id from table1
I have written a Java class which generate and place the XML file in a particular location. This the java class is loaded into Oracle using the loadjava command. When I call the sql java procedure java classn will be called and the XML file is generating.
But my problem is with xml header i.e in the header it is getting as
<?xml version = '1.0' encoding = 'UTF-8'?>
Where as I am generating the xml file from by just java call instead from Oracle the header is as follows
<?xml version="1.0" encoding="UTF-8" ?>
I am thinking that this could be reason with different jar using Oracle side.
I am trying to invoke program from my local Windows machine (exactly java executor, which is in my environment on c:javajdkinjava) using database package with Java stored procedure.
Everything is fired by SQLPLUS script, this script invokes package with Java stored procedure (jar loaded into Oracle) and that procedure is trying to invoke runtime process (syntax:
c:javajdkinjava -cp
and here ara my classes and main jar) using my local java executor. I added all permissions using dbms_java.grant_permisions (execution forced me to give permissions java.io.FilePermission to <<ALL_FILES>> for execute), moreover I added to my database user JAVASYSPRIV and JAVAUSERPRIV role. Unfortunately, beside this I am still getting error:
C:javajdkinjava not found (Note that lookup with PATH isn't done due to the oracle executable being setuid.)
my java program i am executing a pl/sql function using callable statement i checked everything in the function and the function is created without compilation errors in sql*plus environment, and i gave all DBA permissions to the user, but i got the error like below
java.sql.SQLException: ORA-06550: line 1, column 28: PLS-00201: identifier 'NAME' must be declared ORA-06550: line 1, column 7: PL/SQL: Statement ignored
and i wrote the function like below for the below table
and the java program is like below try{ Class.forName("oracle.jdbc.driver.OracleDriver"); Connection connection=DriverManager.getConnection(dbURL,dbUserName,dbPassword); CallableStatement st=connection.prepareCall("{?=call
The Oracle machine A (11R1) is placed in San Jose. The Oracle machine B (10R2) is placed in Sydney.
I need to develop a daily replica from A to B. I don't need the entire db, but only some single schema.
The entire DB size is 1TB.The exp pump gzipped dump size will be 5+GB.Tnsping from A to B takes 500+ ms.The regular A exp pump -> ftp -> B imp pump will be too slowly because of the poor network.Which way it would be the best to implement it?
Our product uses Oracle11gR1 and in new release we are going to use Oracle11gR2. For this we are performing following steps:
(1) Install Oracle11gR2 on a machine where our product (Oracle11gR1) is already installed. (2)Upgrade Oracle11gR1 schema to Oracle11gR2. (3)For using upgraded schema in our product installer we create clone of upgraded schema. (4)For creating clone we are using Oracle11gR2 DBCA utility. (5) Clone files are successfully created (DBC, CTL, DBF).
Now we performed same steps from another machine and DBF file size changed very much. On one machine it was 89 MB and on second machine it was 150 MB. There is no different in schema and both machines are Windows 7 machines.
Tor educe size of schema we tried different space reclamation commands but size is not changing.
I need to call a PL/SQL stored procedure from a C program. Something like this sample program provided by Oracle -
main() { int i; EXEC SQL BEGIN DECLARE SECTION; /* Define type for null-terminated strings. */ EXEC SQL TYPE asciz IS STRING(20); asciz username[20]; asciz password[20]; [code].......
The question is - how is the Stored procedure get_employees declared ? Or more specifically, how is the salary parameter declared in get_employees ?
I have one package, that included so maany ref. cursor package..Now , i want to execute of one procedure in this package, how can i do it ..
CREATE OR REPLACE package Pkg_HR As Type Typ_Cur Is Ref cursor; procedure getHR_initiate(pvFinYr Varchar2, Cur_HR_Init OUT TYP_CUR); procedure getFin_Yr(Cur_Fin_Yr Out TYP_CUR); procedure getCutOFfStatus(pvAppsee1_Appsr2_Review3 Varchar2, pvFinYr Varchar2, Cur_HR_Init OUT TYP_CUR); procedure SetEmp_For_FinYr(pvFinYr Varchar2, Cur_Emp OUT TYP_CUR); End Pkg_HR ;
My Package Body is :
CREATE OR REPLACE package body Pkg_HR As procedure getHR_initiate(pvFinYr Varchar2, Cur_HR_Init OUT TYP_CUR) IS Begin Open Cur_HR_Init For Select HR_FINYR HR_FinYr, To_Char(HR_PERIOD_FROM,'DD/MM/RRRR') HR_PERIOD_FROM
My need is to execute procedure in cycle. I can run
EXEC zoo.pkg_z184.rep184_fill( date '2011-09-28' ); EXEC zoo.pkg_z184.rep184_fill( date '2011-09-29' );
But I'd like to do it in cycle when the period is much bigger. Here is my try to do it:
begin
for l_row in ( select date '2011-09-27' as arcdate from dual union all select date '2011-09-28' as arcdate from dual union all select date '2011-09-29' as arcdate from dual union all select date '2011-09-30' as arcdate from dual ) loop EXEC zoo.pkg_z184.rep184_fill( l_row.arcdate ); end loop; end;
It returns error:
ORA-06550: line 9, column 6: PLS-00103: Encountered the symbol "ZOO" when expecting one of the following: := . ( @ % ;
The symbol ":=" was substituted for "ZOO" to continue.
I have a procedure which will execute on every Monday. Same is not executed last Monday. Can I execute the Procedure on some other day with out changing the actual procedure?
I have written a package in that package i have written a procedure. That procedure has two i/p and two o/p variables. I am calling the procedure using the below syntax.
I have created the following procedure. Since I am using this first time I don't know how to execute this.

Is there a way to grant EXECUTE on a group of procedures/functions/packages to a particular role , in a single statement ? Or we have to do it one by one... like GRANT EXECUTE on event_main to role1, GRANT EXECUTE on event_main2 to role1, GRANT EXECUTE on event_main3 to role1,
I'm running a PL/SQL with a For Loop cursor, but when trying to execute it doesn't run. It is as if there is no data, but I ran the cursor separately in a SQL Plus session and it runs perfectly. I'm enclosing the file with the procedure.
