Using PL/SQL packages and JDBC

How can I call a PL/SQL procedure stored in a package using JDBC?

Sorry, I didn't realise ..... however the difference is trivial. In the example they call a procedure named nxt_flight_time_and_num_routes using
CallableStatement l_stmt = m_connection.prepareCall("begin nxt_flight_time_and_num_routes(?,?,?); end;");
If the procedure happened to be in a package called 'flight_info' it would simply be called as
CallableStatement l_stmt = m_connection.prepareCall("begin flight_info.nxt_flight_time_and_num_routes(?,?,?); end;");

Launch HTML Page using PL/SQL package

Hi,
Am trying to launch an HTML page in which i have used javascripting using

while registering the function , only in the HTML call i have given package.procedure name
are there any special parameters that i need to pass in the package.
How do i build the url of the page to display in the package?
the problem i am clicking on the function i am getting logged as the function is unable to find the right url i guess

MOD_PLSQL is an Apache (Web Server) extension module that allows one to create dynamic web pages from PL/SQL packages and stored procedures. It was formerly called the Oracle PL/SQL Cartridge and OWA (Oracle Web Agent). So I guess, you are referring to the same.
As for UI development, why don't you use the Oracle Applications Framework [OAF]? That's the standard for any UI development in apps. As mentioned earlier, mod pl/sql code is not supported on R12, so why use it? Better have a look at OAF.

Windows Authentication using Microsoft SQL Server 2005 JDBC Driver

Hi,
I am using Microsoft SQL Server 2005 JDBC Driver to connect to SQL Server 2000 database, can anyone tell me the connection URL for windows authentication. SQL authentication is working fine.
DataDirect has drivers for windows authentication but I am not using it.

You can't do it with the Microsoft driver. There's a free driver called jTDS that may be able to (I don't know).

Trying to fine and integrate oralce.sql package into jdbc

Hello all, I am trying to find the oracle.sql pacakage in Oracle 9i. I have found the classes.zip file from another person in this forum. they said something about setting the classpath to this zipfile and then the oracle.sql package will be available for import.
I set to classpath to the zip file but my JSP compiler still could not find the package. I even tried to unzip the classes111.zip file but that did not work either. There is a classes111.jar file in that same folder which i also put in the classpath. NOthing seems to work. Can anyone tell me what I am doing wrong as i really want to use the oracle.sql.BLOB class for my project. Many thanks for anyone's input.
Andrew

What container are you using? Tomcat? Oracle9iAS? Websphere? Each container has its own peculiarities about setting up classpaths for their JSP compilers, and none of them use the default system classpath for this purpose.
For Tomcat, put the jar file (I don't believe Tomcat looks at .zip files) in the $CATALINA_HOME/shared/lib folder. For Oracle 9iAS, place the zip or jar in a library folder as defined in the application.xml file, usually $OC4J_HOME/j2ee/home/lib. (You're probably not using Oracle, they include their driver in the container path by default.)
Find out where your container is looking for library files, and place your library there. And have fun!

How to use Native SQL statement in JDBC receiver interface

Dear All,
Can any one please help us in using Native SQL statement in a JDBC receiver channel. The reason why I need to use Native SQL statement instead of standard XML structure is that I need to execute a dynamic SQL query in third party database system lke:-
Select Field1 Field2 from TABLE Where Field3 like "%Name'
I expect the the response in the form of XML file which I can pick up using synchornous interface as mentioned on help.sap.com:-
http://help.sap.com/saphelp_nw04/helpdata/en/64/ce4e886334ec4ea7c2712e11cc567c/frameset.htm
http://help.sap.com/saphelp_nw04/helpdata/en/64/ce4e886334ec4ea7c2712e11cc567c/frameset.htm
The value for %Name can change dynamically according to the transaction and hence cannot be inluded as a KEY element in standard XLM structure,
Hence I need to know:-
1. What message mapping I should use in case if I have to use Native SQL statement.
2.What operation mapping I should use in case if I have to use Native SQL statement.
If guess correclty I may have to use Java mapping to do the above activities. Hence I want to know
3 .How do to go about it to do the Java mapping.
Thanks

You can use a stored procedure, and call it from jdbc receiver adapter.
I also solve this issue, with a DBLookup in message mapping. You can refer to my blog, and this usefull 3d:

Working with PL/SQL Packages and Extension SDK

Hi,
I'm working on an Extension for SQL Developer. I want this Extension to wrap my PL/SQL Packages.
The Situation:
I got an Oracle DB 10g Revision 1 so I can't use the dbms_ddl call to wrap my Packages. I have to use the wrap.exe Utility.
When I right click on a PL/SQL Package I can choose "Wrap it!" and the Extension does the following: It implements an oracle.ide.controller.ContextMenuListener and when the handleEvent function is called I cast the Context Parameter to a oracle.dbtools.raptor.navigator.plsql.PlSqlNode Object.
Through the getSource function I get source code, print it into a file wrap it and write it back to the database.
But I have to call this for both the package body and the package header. How can I got the header if my oracle.dbtools.raptor.navigator.plsql.PlSqlNode Object is the body or the body if my oracle.dbtools.raptor.navigator.plsql.PlSqlNode Object is the header with the Extension SDK? There has to be a Way, cause there is also a standart function called "Save Package Spec and Body".
Can someone help me, please. :-)
Thanks
Andi
P.S.: I'm sorry for my bad english. :(

Greetings,
If you are using the HTP/HTF procedures/functions then the following code does what you are asking:
htp.formOpen( curl => 'schema.package.procedure_name', cmethod => 'post');
which would generate the following HTML:
<FORM ACTION='schema.package.procedure_name' METHOD="post">
The names of <INPUT> items between the <FORM> tags should match parameter names in your PL/SQL procedure.
Thanks,
Dale

Errors using weblogic sql driver: "No JDBC connection can be made because the transaction state is marked rollback"

One of our customers starts to encounter this error message recently.

There is no nested calls of these methods.

Joe,
We got the exact same error message. The error came after we got theJDBC connection,
and trying to create statement off it.
It occurs intermitently when we are running another standalone JAVAapp to do
some end of day work, which results in the DB Server being very busy(90+%CPU
usage) for about 5 minutes. We see a surge of requests to the WLSJDBC Connection
pool. This would sometimes result in all our subsequent DB requeststo fail and
lead to a crash.
We are using WLS6.0SP1. I do not think there's a 30 seconds wait leadingto a
connection timeout that caused this(rather it is the end effect).
Can you give us a more detailed explanation? Is there a miscommunicationbetween
our DB(Sybase12) and WLS?Hi. It looks to you like it's after you get the connection, but really
it's when the server is
gettng the pool connection. For performance/synchronization reasons we
do a clever
delay: When your code asks for a pool connection we quickly give you
the pool wrapper,
but we delay actually reserving the real underlying DBMS connection until
your first
real need for a connection, at your first JDBC call, such as createStatement()
etc.
It is while waiting for a pool connection long enough for the transaction
coordinator
to have timed you out before you ever get a chance. It's nothing to do
with the
DBMS or even JDBC, I believe. I think the weblogic server either has
too few execute-threads
and/or too few CPU cycles to do the work load.
Okay, so there's a lazy initialization of the connection.
From reading our log I believe our failur is immediate rather
than waiting for 30+ seconds(the default setting) from the DB,
the timeout occurred later as a result. At the time either because the DB Server
is very busy.
Since we are running WLS6.0 we have only one connection pool,
we have defined a max of 150 threads in the pool. While this
is happening the DB Server is being pinned by an overnight job,
but the WLS Server is not busy at all. The DB and WLS resides
on different physical boxes.
We also have a thread dump from the WLS console when we rebooted the server, it
showed that we are hanging on to the thread & jdbc
connections after these exceptions has occurred instead of releasing them, note
"16083"(~4.5 hours) seconds has passed:
142 116222 Retry rollback request for tx: 'transaction=(IdHash=2963855,Name =
[EJB UserManagerBeanImpl.signalICUserServletHeartBeat()],Xid=30643:8f3838f3709bf53d,Status=Rolling

Scheduled Trigger
So I would argue this problem actually chewed up resources on the WLS server.

BI UDI data load conflict using MS SQL Server and date fields

Hi BW Experts!
We have found some unexpected problems when we are trying to perform a data extraction process from an SQL database (non-SAP application).
We are using the BI UDI tool (JDBC Driver/Connector).    The basic data extraction works properly, however we have some specific problems to work with SQL Server fields defined as Date Time.
The JDBC driver automatically intermediate the communication and translate these fields splitting the original SQL date time field into two separated fields with suffix _D (for date) and _T (for time).
It works perfect for extraction, but it doesnt work well when we try to restrict the data selection based on these fields.
When we put a date selection into the infopackage data selection area (we already have tried several date formats), the system simply ignores these selection parameters and send a SQL statement without WHERE clause to DBMS.
Please, anybody has experienced anything like this or know somethings that could help us?
This is a standard limitation from SAP BI UDI?
Thanks in advance and best regards,

Hi Matt and Thomas
Many thanks for your replies.
Yes I have to do the join. Even worse I have to write an Aggregate query like this!
Select o.F1,o.F2, m.F1,m.F2, count(*)
from
table@oracleServer o,
table@microsoftSQLServer m
where o.F1=m.F1
group by o.F1,o.F2, m.F1,m.F2;
These are 2 different systems (hardware & software) which actually do the same job, they produce transactions for a common business entity. Kind of, both sell tickets for the same ABC ferry company.
I can not put them side by side on the dashboard, as I need to aggregate the data and present it maybe in a Oracle BI Report for Accounting and Financial reconciliation purposes.
The truth is, as it is. I can't change it, is too late.
I have to device a way to harvest both systems as they are. I don't want to move around data. I thought looking at Oracle BI I could write SQL against multiple Data Sources. I am struggling to find a way. As it seems that it can "SQL query" 1 data source at a time.
I have been hinted on another forum (OracleTURK) to use Oracle Transparent Gateways and Generic Connectivity. http://download.oracle.com/docs/cd/B19306_01/server.102/b14232/toc.htm
Shame, I have to pay licenses for OWB and Oracle Transparent Gateways. I thought DB vendors can do better. Why do I have to pay to access the other 50% of the market.
I can understand the performance implications this might have. Because of it I might even be forced at the end to move data (ETL) into a separate database, slice it into partitions and manage it that way. Pitty because currenlty I only need one report out of these systems but seems like will be dear to get.
Thank you for all your help.

Huge memory leaks in using PL/SQL tables and collections

I have faced a very interesting problem recently.
I use PL/SQL tables ( Type TTab is table of ... index by binary_integer; ) and collections ( Type TTab is table of ...; ) in my packages very widely. And have noticed avery strange thing Oracle does. It seems to me that there are memory leaks in PGA when I use PL/SQL tables or collections. Let me a little example.
CREATE OR REPLACE PACKAGE rds_mdt_test IS
TYPE TNumberList IS TABLE OF NUMBER INDEX BY BINARY_INTEGER;
PROCEDURE test_plsql_table(cnt INTEGER);
END rds_mdt_test;
CREATE OR REPLACE PACKAGE BODY rds_mdt_test IS
PROCEDURE test_plsql_table(cnt INTEGER) IS
x TNumberList;
BEGIN
FOR indx IN 1 .. cnt LOOP
x(indx) := indx;
END LOOP;
END;
END rds_mdt_test;
I run the following test code:
BEGIN
rds_mdt_test.test_plsql_table (1000000);
END;
and see that my session uses about 40M in PGA.
If I repeat this example in the same session creating the PL/SQL table of smaller size, for instance:
BEGIN
rds_mdt_test.test_plsql_table (1);
END;
I see again that the size of used memory in PGA by my session was not decreased and still be the same.
The same result I get if I use not PL/SQL tables, but collections or varrays.
I have tried some techniques to make Oracle to free the memory, for instance to rewrite my procedure in the following ways:
PROCEDURE test_plsql_table(cnt INTEGER) IS
x TNumberList;
BEGIN
FOR indx IN 1 .. cnt LOOP
x(indx) := indx;
END LOOP;
x.DELETE;
END;
or
PROCEDURE test_plsql_table(cnt INTEGER) IS
x TNumberList;
BEGIN
FOR indx IN 1 .. cnt LOOP
x(indx) := indx;
END LOOP;
FOR indx in 1 .. cnt LOOP
x.DELETE(indx);
END LOOP;
END;
or
PROCEDURE test_plsql_table(cnt INTEGER) IS
x TNumberList;
empty TNumberList;
BEGIN
FOR indx IN 1 .. cnt LOOP
x(indx) := indx;
END LOOP;
x := empty;
END;
and so on, but result was the same.
This is a huge problem for me as I have to manipulate collections and PL/SQL tables of very big size (from dozens of thousand of rows to millions or rows) and just a few sessions running my procedure may cause server's fall due to memory lack.
I can not understand what Oracle reseveres such much memory for (I use local variables) -- is it a bug or a feature?
I will be appreciated for any help.
I use Oracle9.2.0.1.0 server under Windows2000.
Thank you in advance.
Dmitriy.

Thank you, William!
Your advice about using DBMS_SESSION.FREE_UNUSED_USER_MEMORY was very useful. Indeed it is the tool I was looking for.
Now I write my code like this
declare
type TTab is table of ... index binary_integer;
res TTab;
empty_tab TTab;
begin
res(1) := ...;
res := empty_tab;
DBMS_SESSION.FREE_UNUSED_USER_MEMORY;
end;
I use construction "res := empty_tab;" to mark all memory allocated to PL/SQL table as unused according to Tom Kyte's advices. And I could live a hapy life if everything were so easy. Unfortunately, some tests I have done showed that there are some troubles in cleaning complex nested PL/SQL tables indexed by VARCHAR2 which I use in my current project.
Let me another example.
CREATE OR REPLACE PACKAGE rds_mdt_test IS
TYPE TTab0 IS TABLE OF NUMBER INDEX BY BINARY_INTEGER;
TYPE TRec1 IS RECORD(
NAME VARCHAR2(4000),
rows TTab0);
TYPE TTab1 IS TABLE OF TRec1 INDEX BY BINARY_INTEGER;
TYPE TRec2 IS RECORD(
NAME VARCHAR2(4000),
rows TTab1);
TYPE TTab2 IS TABLE OF TRec2 INDEX BY BINARY_INTEGER;
TYPE TStrTab IS TABLE OF NUMBER INDEX BY VARCHAR2(256);
PROCEDURE test_plsql_table(cnt INTEGER);
PROCEDURE test_str_tab(cnt INTEGER);
x TTab2;
empty_tab2 TTab2;
empty_tab1 TTab1;
empty_tab0 TTab0;
str_tab TStrTab;
empty_str_tab TStrTab;
END rds_mdt_test;
CREATE OR REPLACE PACKAGE BODY rds_mdt_test IS
PROCEDURE test_plsql_table(cnt INTEGER) IS
BEGIN
FOR indx1 IN 1 .. cnt LOOP
FOR indx2 IN 1 .. cnt LOOP
FOR indx3 IN 1 .. cnt LOOP
x(indx1) .rows(indx2) .rows(indx3) := indx1;
END LOOP;
END LOOP;
END LOOP;
x := empty_tab2;
dbms_session.free_unused_user_memory;
END;
PROCEDURE test_str_tab(cnt INTEGER) IS
BEGIN
FOR indx IN 1 .. cnt LOOP
str_tab(indx) := indx;
END LOOP;
str_tab := empty_str_tab;
dbms_session.free_unused_user_memory;
END;
END rds_mdt_test;
1. Running the script
BEGIN
rds_mdt_test.test_plsql_table ( 100 );
END;
I see that usage of PGA memory in my session is close to zero. So, I can judge that nested PL/SQL table indexed by BINARY_INTEGER and the memory allocated to it were cleaned successfully.
2. Running the script
BEGIN
rds_mdt_test.test_str_tab ( 1000000 );
END;
I can see that plain PL/SQL table indexed by VARCHAR2 and memory allocated to it were cleaned also.
3. Changing the package's type
TYPE TTab2 IS TABLE OF TRec2 INDEX BY VARCHAR2(256);
and running the script
BEGIN
rds_mdt_test.test_plsql_table ( 100 );
END;
I see that my session uses about 62M in PGA. If I run this script twice, the memory usage is doubled and so on.
The same result I get if I rewrite not highest, but middle PL/SQL type:
TYPE TTab1 IS TABLE OF TRec1 INDEX BY VARCHAR2(256);
And only if I change the third, most nested type:
TYPE TTab0 IS TABLE OF NUMBER INDEX BY VARCHAR2(256);
I get the desired result -- all memory was returned to OS.
So, as far as I can judge, in some cases Oracle does not clean complex PL/SQL tables indexed by VARCHAR2.
Is it true or not? Perhaps there are some features in using such way indexed tables?

Is there any restriction using pl/sql packages depending on Oracle Version?

Hi everybody. Our company is using a mix of pl/sql packages to call web services and process xml inside stored procedures. We are using UTL_HTTP, UTL_DBWS and UTL_XML. Our client asks if there is any restriction using those packages on a Standard One licensed database? Does we need an upgrade p.e. enterprise edition to use those packages? I test all our development on a Express Edition, and there is no restriction. We run the same test on a Standard One and Enterprise Editions and the result was the same, no restrictions.
To use those packages does we need an upgrade to enterprise edition?
Xavier.

the packages that you mention are not restricted to a particular version.

Use of SQL Server and Oracle Simultaneously

Hello,
Is it possible to have Oracle and SQL Server used simultaneously? Here, developers will be accessing both databases at the same time, whereas they are some ease of implementations at one Database, which can't be found in another database.

I am able to retrieve with simple OUT Parameters from the stored procedure in the application without having to use refcursor. Is this a bad thing in the use of other data types instead of refcursors?
I was able to have only a varchar and this worked fine.PL/SQL is a formal procedural language with a number of object orientated programming features. Of course functions can return all kinds of data types - even objects and arrays and collections and pointers (called LOB locators).
All SQL in Oracle are parsed and stored in the server as cursors. The ref cursor data type in PL/SQL is a variable type that contains the handle of a cursor in the server - its "special ability" is passing this PL/SQL variable structure to a client (like Java or .Net) and have the client consume the output of the cursor.
Ref cursors allow you to move a lot of business logic and validation and processing into PL/SQL - and have PL/SQL do the complex stuff and create the SQL cursor and then simply pass the cursor handle to the client as a ref cursor data type. You can easily maintain this code, introduces changes, tune for performance, without having to touch a single byte of client code.
But functions are not there simply to pass ref cursor handles to a client. They can do various other stuff and return all kinds of data types and structures.

Using unlinked sql command and table in a subreport

All,
Does CR allow using an unlinked sql command and a table in the same subreport? I am passing the CurrentCEUserName from the main report to the sql command in the subreport (via linked parameter). The sql command then executes a query to pass the parameter to the database (example: select myfunction('{?myparam}' from dual). I need this to run before subreport's table query is executed.
This all appears to work except that the parameter passed to the sql command isn't set when the command executes. The value is always null when the sql command is executed. If I add the parameter to the report output it shows the expected value.
Also, if I have a subreport that just has a single sql command the parameter is set correctly prior to executing the command.
any help would be appreciated.
thanks!

If you are looking for Crystal to run the SQL Command, then the SQL it generates itself, I think the answer is no, it won't do that. Crystal expects all of the data sources to be linked, I believe. I'm not sure what you would expect to happen if they are not... However, you can make your SQL Command something like (MS SQL; sorry, it's been too long since I've used Oracle...):
declare @result varchar(100);
set @result = ( select myfunction('{?myparam}') );
select * from table;
which would run the first select calling your function, basically throw away the result (or you can do with it as needed), then return the fields from your table.
HTH,
Carl
