(I actually raised a service request on this and then told my rep what I thought about the answer I received--some thing along the line of money grubbing so and so....)
How I can send a message from oracle to Java Desktop Application which is working like server program?You can make a table and poll it from time to time from the Java side and write and commit what ever you want to the table. I do not know any way to send a signal from Oracle DB an external Java application--Java or PL/SQL stored procedure.

ORA-04030: out of process memory when using Java Stored Procedures
Hello,
I have a problem using Java Stored Procedures in Oracle 10g.
My Java application performs http posts to a webservice and the response is parsed in order to populate some DB tables.
There is a scheduled job which calls the Java Stored Procedure every x minutes.
No matter of the 'x minutes' values - after about 160 - 200 calls I get this error:
ORA-04030: out of process memory when trying to allocate 1048620 bytes (joxp heap,f:OldSpace)
ORA-04030: out of process memory when trying to allocate 2097196 bytes (joxp heap,f:OldSpace)
The job stops just while is posting the http request. The weird thing is that almost each time the first http post request I get this error:
java.net.ConnectException: Connection refused
at java.net.PlainSocketImpl.socketConnect(Native Method)
at java.net.PlainSocketImpl.doConnect(PlainSocketImpl.java:305)

So, The out of process memory occured each time just before getting such an error, and I suspect to be a connection between these errors.
Tech details:
1. OS: WinXP
2. Oracle 10.1.0.2.0
3. To perform http post I use HttpClient 3.1 from Apache.
4. I checked the http connection to be closed each time, and this is done.
5. I checked the oracle statement and connection to be closed each time and this is done
6. The JVM error (logged in .trc files of Oracle) is:

Can be a problem with JVM threading under Oracle ?The server prcess failed to allocate more memory for large objects ( in Oldspace).
If you Google ORA-04030, you will see several recommendations to work around this.
The Java VM in the database already has HttpClient, i don't know why you are loading the Apache HttpClient but this might not be the surce of the problem.

KalCan I create threads inside Java Stored procedures?

Kal Hi Kal,
I don't mean to be rude, but have you tried it? Personally, I
haven't tried it (since I didn't have the need).
You don't say what version of Oracle DBMS you are using, but I
am using 8.1.7.3 on Solaris 7, and according to Oracle's
"Oracle 8i Java Developer's Guide", there is no restriction
(of-course, that depends on what you call a "restriction" :-)

Java Stored Procedure functions in SQL DML - multiple invocations
When running a java stored procedure as part of a DML statement the procedure is invoked 10-15 times for each row that is updated.
For example:
Update mytable set mycolumn = myjsp(somecolumn);
I undertand that this was a known bug with the JDBC driver. Has it been fixed? Is there a workaround?
We are using 8.1.6 on NT 4
Thanks
JulianHello ,
I tried here, and it seems to call the function once for each row
eg :
package package90;
public class Class1 extends Object {
public int get_data(int i)
return i+10;
Published the get_data function as
myproject67.get_data
SQL> connect scott/tiger@orcl8i

[b]Java Stored Procedure generating ora-932 in Oracle 9i [/b]
Hi ,
I have written a Java Stored procedure. And I have written a wrapper function as bellow
FUNCTION "GENERATE_AC_EXCEL_REPORT_FN"
( refCursorCall VARCHAR2, fromDate Date, ToDate Date,
nsn VARCHAR2, period varchar2, site VARCHAR2,
vendor VARCHAR2, spotbuyType VARCHAR2, dataType, VARCHAR2 )
return number
as LANGUAGE java
NAME 'accountingExcelReports.excelPrinter( java.lang.String, java.sql.Date, java.sql.Date, java.lang.String,java.lang.String , java.lang.String,
java.lang.String, java.lang.String , java.lang.String) return int';
This function returns 1000 upon successful execution.
This used to execute fine in Oracle 8.1.7.
We installed Oracle 9i recently.
Server version is 9.2.0.2.1.
Jserver version is 9.2.0.2.0 .
Now The function call works fine for the first time. And When execute it for sencond time in the same Session,
The program is erring out saying inconsistent data typpes.
This is happening during passing parameters.
SQL> select
2 generate_ac_EXCEL_report_fn('Period', to_date('7-1-2002','MM-DD-YYYY'),
3 to_date('7-31-2002','MM-DD-YYYY'), NULL,

4 NULL, NULL, NULL, 'ALL' ,'SPOTBUY') from dual;
select
ERROR at line 1:
ORA-00932: inconsistent datatypes: expected IN Conversion failed
And upon further testing, i noticed this happens when the dates are passed. If date parameters are nulled out, Then the program executes perfectly any number of times.
The same program worked fine in Oracle 8.1.6
Any ideas?
Please help.
Thanks,
SrinivasHi Srinivas,
you shouldn't be calling conn.close() and its not needed when using Server Side Internal driver. If you are calling conn.close, then .....
extract from JDBC user guide
If you do call the close() method, be aware of the following:
All connection instances obtained through the defaultConnection() method, which actually all reference the same connection object, will be closed and
unavailable for further use, with state and resource cleanup as appropriate. Executing defaultConnection() afterward would result in a new connection
object.
Even though the connection object is closed, the implicit connection to the database will not be closed.

Trying to use Java Stored Procedure to create directories
Hello, I have the followqing simple Java code I am using to run OS commands from PL SQL. When I call my function, it does not create the directory, but it does say completed successfully. Here is the code and the call I am using:
CREATE OR REPLACE AND COMPILE JAVA SOURCE NAMED Command

import java.io.*;
import java.util.*;
public class Command{
public static void run(String cmdText)

END;
/Any ides on why this is not working? Any better suggestions for doing this? I need to be able to create directories from with in a PL SQL Stored Procedure. Thank youSimple dude, you java code returns void, whereas your function returns an int. Change the java code to return an int (and return an int)

Problem creating dataset using db2 stored procedure in Eclipse BIRT
Hi,
I am using DB2 9.7 Express Edition in Eclipse BIRT(version 2.5.1) for generating reports. I have used Type4 driver for jdbc connection.
For that, I have established jdbc connection using db2jcc.jar and db2jcc_license_cu.jar files.
I have successfully created data source, say DB2BIRT having following requisites-
Driver Class - com.ibm.db2.jcc.DB2Driver ( v3.50)
Driver URL - jdbc:db2://localhost:50000/database_name
User name - user_name
Password - Password
I have written some stored procedures and trying to use resultsets from those stored procedures into my report..
The stored procedures having involvement of only single resultset are working absolutely fine for new dataset using above DB2BIRT.
But, I am unable to create new dataset using stored procedures those having involvement of multiple resultsets.
I am getting following error as -
org.eclipse.birt.data.engine.odaconsumer.PreparedStatement$SequentialResultSetHandler getMoreResults
SEVERE: Cannot get more result sets from the statement.
Cannot get the result set.

Moreover, I tried to resolve above issue by changing Driver Class from com.ibm.db2.jcc.DB2Driver ( v3.50) to com.ibm.db2.jcc.uw.DB2StoredProcDriver ( v3.50)
So again while *"Test Connection"* for new Data source using this new driver class for stored procedure, there is an error reflection as -

Can anybody address my this issue for successful implementation of stored procedure(with involvement of multiple resultsets) for creating Data set in Eclipse BIRT ?
I will be really thankful.
Thanks in advance,
ManasiWell, in my stored procedure I have used 2 to3 cursors(as per my business logic) and all cursors except one are holding result sets. That exceptional cursor is intended for holding as well as returning result set after call to the procedure. And its perfectly running on db2 and returning the desired output. The problem is with Eclipse. The same procedure is not working in Eclipse BIRT.

Java, Stored Procedure/Function, JSP
Hello All,
Is there any one who can help.
I would like to return a record set from a stored function and display the results with a JSP program.
The same function is currently being used to retrieve data for a related process, but that process uses a procedure to call the function and the results are written to a database table. This works fine.
This time I would like to create a record set and display the results on screen, but I am having problems.
ResultSet rsTimecard = null;
Connection conn = sqlMgr.getConnection();
CallableStatement cs = conn.prepareCall("{ ? = call TA_WEBDBA_HOURS_USE_PKG.aftimecard_jocas_records(to_date('01-OCT-2004', 'DD-MON-YYYY'), to_date('30-OCT-2004', 'DD-MON-YYYY')) }");
cs.registerOutParameter(1, Types.OTHER); // This is line 99. Types.OTHER is the Invalid column type that the system is complaining about.
cs.execute();
rsTimecard = (ResultSet) cs.getObject(1);
<table width="100%">
<%
while(rsTimecard.next())
%>
<tr>
<td colspan="1" width="10%">
</td>
<td colspan="1" width="10%">

I get:

Generating Data for INSERT using a Stored Procedure, Function and Cursor
I've written a function that I finally got to compile, but was not successful in importing and inserting the data needed to populate a table with at least 1800 rows. Here's what I needed to do:
-- Generate a random test score ranging from 20 to 100 (already done)
-- Generate a random final grade for the course ranging from 4 to 0 (representing A to F) (already done, but question below.
-- Use conditional statements based on the counter to assign three courses (already done -- see SQL statements)
-- Process no more than 95% of the students (300) for test 1.
-- For test 2, process no more than 80% of the students who took test 1. Student cannot take test 2 unless the student takes test 1 (does this require a trigger? If so, how would I go about doing this?)
-- Use a function or another subprocedure to process the grade using IF-ELSIF statements
For example, I've tried the following statements:
For procedures
IF birth_date BETWEEN to_date('01-Jan-89 AND to_date('31-Dec-89','dd-Mon-yy') THEN
school_grade := 6;
AND for functions:
IF birth_date BETWEEN to_date('01-Jan-89 AND to_date('31-Dec-89','dd-Mon-yy') THEN
RETURN (6);
RETURN;
- or -
IF birth_date BETWEEN to_date('01-Jan-89','dd-Mon-yy') AND to_date('31-Dec-89','dd-Mon-yy') THEN
school_grade := 9
RETURN school_grade;
-- Read the birth_date into the main procedure so that the value returned from the subprocedure or function can populate the birth_date column.
To give you an idea of what I've already done:

When I executed the main procedure, no data populated the student_table. I've tried several things, but I was not still able to populate the student_fact table (I've been at this for more than a week now, but haven't figured a way to populate the student_facts table with at least 1800 rows). Can you tell me what I need to change (if anything) whether if I need to structure things differently? I'm thinking that I missed something in calling the birth_date into the main procedure or returning the value from either a function or subprocedure. Related to the random final grade -- is there a way to sum the totals of the test scores (each student will have three), and generate a final grade from these values.
I also compiled successfully a package containing this same information, but don't know how to execute it to see whether this approach works.
Many thanks to anyone who can help.

Return national language strings from java stored procedures
Hi, all.
How does i can return String which contains national characters from java stored procedure? I.e. convert UTF java string to national language of database. It's does not processing automatically (why?).
declaration of procedure:
CREATE OR REPLACE FUNCTION TestNLSString RETURN VARCHAR2
AS
LANGUAGE JAVA
NAME 'test.SomeClass.getNLSString() return java.lang.String';
SELECT TestNLSString AS X FROM DUAL;

OS: Windows 2000 Server
Oracle Server version: Oracle 8.1.7.1.4Ok. I had a specific problem.
I want to use java stored procedure (function) to make a connection to remote db using supplied connection parameters make some quieries there end return results in a form of structured data - object.
I have defined an object type in a database where the function will reside. I granted execute privilege to public user on this type, made public synonyms to both, the object type and the function, so anybody connected to the same database would have an access to this functionality.
I supposed that if I supply connection parameters for some other user but the same database when running the function, everything should go smooth. Yeah.
My java code executed ok: it made a connection to the db with some x user, it resolved object type descriptor given (oracle.sql.StructDescriptor), but pl/sql wrapper function reported the error I've mentioned. If I executed the function giving it the connection parameters for same account as where object type was declared, everything went fine.
My final solution is:
Make TWO! connection in java code: 1st for ("jdbc:default:connection:"), 2nd for remote database account.
Use first connection to construct oracle.sql.StructDescriptor
Use second connection to retreive data from remote db -
Using JNDI from Java Stored Procedures
Hi,
we want to call external services (mostly via middle tier/J2EE) from within the database (9i Rel. 2) using Java Stored Procedures and JNDI.
Does anybody have some hints/samples how to do this? Will we have to use oc4jclient.jar? If yes, how? Where can I find some more detailed documentation?
Lot's of questions...
Thank
MatthiasUh, not JNI but JNDI you asked. And use of JNI should be generally discouraged unless there is absolutely no other way (like co-located CORBA code for decoupling+speed). Can you direct me to a HOW-TO Oracle DB JVM configuration page? I want to know how to configure the internal DB JVM in a hurry.
Thank you,

nullI had a similar issue, the reason for that was picking the incorrect partner link.
Make sure the name of the selected partner link in the invoke output variable is matching with the Assign, in you case lets say you mapped the
Invoke
output variable is invoke_1_CallStoredProcedure_OutputVariable ( not nvoke_1_CallStoredProcedure_OutputVariable_1)
From
<Invoke_1_CallStoredProcedure_OutputVariable>
<LF_STATUS>
To
P_lf_status ( variable)
most of the time multiple variables are created when we try to select the output variable s in the Invoke. -
Unable to access Custom UDTs returned from a Java Stored Procedure
Hi,
I have a UDT in the DB :-
create type contactrecord as object (
CN_ID NUMBER(8),
CN_TITLE VARCHAR2(40),
CN_FIRST_NAME VARCHAR2(25)
and this is the corresponding java class ContactDetails.java that maps to this UDT, that I loaded in the Aurora VM.
package package1;
mport java.sql.SQLData;
import java.sql.SQLException;
import java.sql.SQLInput;
import java.sql.SQLOutput;
public class ContactDetails implements SQLData
private String sql_type;
private long CN_ID;
private String CN_TITLE;
private String CN_FIRST_NAME;
public String getSQLTypeName() throws SQLException
return this.sql_type;
//implementation of readSql
public void readSQL(SQLInput stream, String typeName) throws SQLException
sql_type = typeName;
CN_ID = stream.readLong();
CN_TITLE = stream.readString();
CN_FIRST_NAME = stream.readString();
public void writeSQL(SQLOutput stream) throws SQLException
stream.writeLong(CN_ID);
stream.writeString(CN_TITLE);
stream.writeString(CN_FIRST_NAME);
//getters and setters for the class vars go here.....
There is another class A.java that has a java stored procedure/function, which I loaded into the Aurora VM
Here is the class.
package package1;
public class A
public static ContactDetails returnObject(String name )
ContactDetails cd = new ContactDetails();
cd.setCN_ID(1);
cd.setCN_FIRST_NAME(name);
return cd;
Then I declared the call spec for A.returnObject() as
FUNCTION returnObject(name varchar2) return contactrecord
AS LANGUAGE JAVA
NAME 'package1.A.returnObject(java.lang.String) return package1.ContactDetails';
Then I tried to call the function returnObject through JDBC calls from a class in another VM.
When I access the object returned by the function, I get a null object.
Here is the Client code:
CallableStatement cs = null;
ResultSet rs = null;
try
cs = conn.prepareCall("{ ? = call returnObject(?) }");
java.util.Map map = conn.getTypeMap();
map.put("ADMIN.CONTACTRECORD", Class.forName("package1.ContactDetails"));
conn.setTypeMap(map);
cs.registerOutParameter(1, OracleTypes.STRUCT, "ADMIN.CONTACTRECORD");
cs.setString(2, "John Doe" );
cs.execute();
ContactDetails cd = (ContactDetails)cs.getObject(1);
System.out.println("contact first name is:-"+cd.getCN_FIRST_NAME()); //Null Pointer here..cd is null....:(
if (cs != null) cs.close();
catch(Exception e)
e.printStackTrace();
Although If I try to access the same function from a pl/sql block, I am able
to access the contactrecord fields.
What could be wrong ..???
I could not find any error with the object mapping, as it works perfectly when I interact directly from my VM to the DB,
without going thru the aurora VM.
I am using a OCI driver to connect to the DB via JDBC.
Thanx in advance for any help at all.
-skShahid,
I too have had bad luck in many cases with the automatic translation of Java types to PL/SQL and back. I think the SYS package on the PL/SQL side which handles some of the conversion is DBMS_PICKLER (there are equivalent Java classes which do the same in that world and seem to execute automagically when a conversion is needed). You might want to double-check the data type mappings against the DOC on OTN to make sure they map 1-1. Also make sure the permissions are granted against your objects to whoever is executing them, etc. Very often, I've resorted to passing simple scalar types between the two languages as in some cases the results with complex types are inconsistent.
Sorry this isn't much help,

Java stored procedures and triggers in lite
Hi
We are using java stored procedures and java triggers in our application for oracle lite database 5.1.
We would like to know whether these procedures and triggers are uploaded or associated with tables or not because triggers are not being fired for the tables.
The question is - how to find the uploaded procedures and triggers in system tables.
We dont find any tables like (all_objects, user_objects) for this in oracle lite system catalogs given in the documentation.
thanks in advance
yugandharI don't have much experience with Lite, but I'm running 9i Personal Edition. Any information about triggers can be found in the "ALL_TRIGGERS" view. You will want to filter out any rows where OWNER = 'SYS' unless you created your triggers as SYS. As for procedures and functions, you can see what you have created in the "ALL_OBJECTS" view where OBJECT_TYPE = 'PROCEDURE' or 'FUNCTION', once again filtering out rows where OWNER = 'SYS'. To see the code of any procedure or function, select substr(text,1,80) from ALL_SOURCE where NAME = 'function name' ORDER BY LINE.
Hope this helps! -

Before you post review the Oracle Database Java Developer's Guide - it shows how to create Java stored procedures and has example code
