Concurrent use of JDBC objects
Which objects in JDBC can generally be used concurrently?
For example, can I use the same Connection object for two simultaneous calls or do I need to create new instances?
How about using a PreparedStatement twice?
For example, can I use the same Connection object for
two simultaneous calls or do I need to create new
instances?Firstly ,how do u propose to do the concurrent call ?
Almost all the critical methods in Connection object are synchronized.Meaning that ,even if u were to call it concurrently ,there isnt anything very much like it.As the object lock mechanism takes care of it.However way u make the concurrent call , one call has to wait till the other releases the object lock.
How about using a PreparedStatement twice?U can use the Statement and PreparedStatement objects as many times as u want .The only issue being that the resulset objects associated with the Statement objects are closed with each new call .

Is it supported to use Microsoft JDBC driver use in Java 7 (and 8) multithreaded applications?
Hello everone
is it supported to use Microsoft JDBC driver (the latest version) with Java 7 multithreaded application?
I am planning to use standard Java 7 threads library and use separate JDBC objects per each thread, i.e. Java threads will not share any JDBC objects among them, only the thread-safe Java collections/data structures will be shared between threads (such as
ConcurrentHashMap etc). The JDBC connections, resultsets, statements, etc will be created and dedicated per each individual thread.
If it is supported - do you expect this design to scale-up well or am I better off using multiple but single-threaded Java/JBDC programs to access SQL Server 2012/2014 from Microsoft JDBC driver?
Thanks

Yes, so long as:

>do you expect this design to scale-up well or am I better off using multiple but single-threaded Java/JBDC programs >to access SQL Server 2012/2014 from Microsoft JDBC driver?
Using threads should scale better than using processes (at least on Windows), as there is quite a bit of overhead with a process. Each process has it's own JRE, it's own GC heap, its own threads...
The bigger question, though, is how this scales on the SQL Server. Your throughput may be limited by resources on your database server, and the thread's workloads may not be able to run concurrently because of locking.

Error in using Dynamic View Object
Hi
I am doing a experiment to create dynamic VO and using it.
Experiment details:
I want to create dynamic VO and dynamic message choice and associate the dynamic VO to dynamicaly cretaed message choice.
code scriplet
In AM
public void dynamicVO()
OADBTransactionImpl txn =(OADBTransactionImpl) this.getTransaction();
OAViewDef viewDef = txn.createViewDef();
// viewDef.addEntityDerivedAttrDef();
viewDef.setSql("select EmpEO.EMPNO, EmpEO.ENAME, EmpEO.JOB, EmpEO.DEPTNO from EMP EmpEO");
viewDef.setExpertMode(true);
viewDef.addEntityUsage("EmpEO","va.oracle.apps.fnd.experiment.server.EmpEO",false);
viewDef.setViewObjectClass("oracle.apps.fnd.framework.server.OAViewObjectImpl");
viewDef.setViewRowClass("oracle.apps.fnd.framework.server.OAViewRowImpl");
viewDef.addPersistentAttrDef("Empno", "EmpEO", "Empno", true, AttributeDef.UPDATEABLE);
viewDef.addPersistentAttrDef("Ename", "EmpEO", "Ename", true, AttributeDef.UPDATEABLE);
viewDef.addPersistentAttrDef("Job", "EmpEO", "Job", true, AttributeDef.UPDATEABLE);
viewDef.addPersistentAttrDef("Deptno", "EmpEO", "Deptno", true, AttributeDef.UPDATEABLE);
// OAViewObject
// ViewObject
ViewObject vo = createViewObject("MyEmpVO", viewDef);
In Controller
public void processRequest(OAPageContext pageContext, OAWebBean webBean)
super.processRequest(pageContext, webBean);
OAApplicationModule am = pageContext.getApplicationModule(webBean);
am.invokeMethod("dynamicVO");
System.out.println("am.invokeMethod dynamicVO");
OAMessageChoiceBean popList = (OAMessageChoiceBean)this.createWebBean(pageContext,OAMessageChoiceBean.MESSAGE_CHOICE_BEAN);
//popList.setListViewObject(pageContext,MyEmpVO);
popList.setPickListViewUsageName("MyEmpVO");
popList.setListDisplayAttribute("Job");
popList.setListValueAttribute("Job");
webBean.addIndexedChild(popList);// when i comment out this a blank page runs otherwise following error appears

Error while saving data using two entity objects (EO)
Hi All,
i am using two entity objects for saving the date in two different tables.
on my page i am having two tables and two save buttons for saving the data in the respective tables.
if i am not entering any data on the first table and putting valid data on the second table and click on the save button.
it is going into error saying "Null Pointer Exception"..
i am using getTransaction.commit() in my AM.
so it is trying to save all the data in both the tables.
i want to commit data of the respective table for which the save button is clicked.
Waiting for ur replyHi,
i am using the following code for saving the data in the AM
// TO SAVE THE JOB ASSIGNMENT DETAILS
public void saveJobAssignmentDetails(String projectId)
EmpAssignmentVOImpl empAssignVO = getEmpAssignmentVO1();
getTransaction().commit(); // Line where i am getting the error
rowNumberCountJobAssign = 0; // IN JOB ASSIGNMENT
// EXECUTING THE DISPLAY FUNCTION AGAIN SO TAHT ALL SAVED FIELD ARE READONLY AS REQUIRED
displayJobAssign(projectId);
if(empAssignVO.getRowCount() != 0)
throw new OAException("Job assignment details have been saved successfully. ",OAException.CONFIRMATION);

Using predefined JDBC database connection in runtime for BC4J
I've created an aplication using BC4J context, however I want to have several distinct users acessing this aplication, so I create the connection to the database using stantart JDBC 2.0, and now I want my application to use this connection instead of the one defined for BC4J.
The database user owner of the objects must be locked.
Is this possible?
Many thanks.
NunoIn Forms I used the following code to change the user at runtime. I created 3 char fields 'u','p' and 'c' for username, password and connect string respectively.
declare
uname varchar2(10);
begin
uname := get_application_property(username);
-- To display your current username
message(uname);
pause;
logout;
logon(:u,:p| |'@'| |:c);
end;
Have a nice day,

How to get handle on currently used socket (JDBC)
Hi all,
I am trying to get the handle of the socket I am using for an Oracle JDBC connection. I created an instance of a Socket bound to the server and the port. However, I am not sure exaclt how to go about BINDING the socket to the JDBC call I am making.
THanks for any help.
RyanSame here. Ive never seen a connection blow up like this. I think we may have found the problem. We are using an OracleXMLQuery object and thought we were hitting an 8.1.7 database....come to find out we are hitting an 8.1.5 database! I think this will resolve the problem (pointing to a newer database).
Thanks for the help.

What is the use of Adapter objects in I.R
what is the use of Adapter objects in I.R
congratulations you successfully opened 1000 new threads...
adapters are components of the adapter engine, their main action is to connect different sysems with each other. therefore are different adapters:
SAP-2-SAP Adapters: like IDoc and RFC
SAP-2-NOT-SAP-ADapters: like JMS, JDBC, HTTP..
and B2B Adapters...
there are some rules in any board that you should accept:
use search first

Workaround for using Oracle JDBC extension with WLS pooling
Reading the newsgroup I saw that many of us encountered the problems
with ClassCastException when tried to use Oracle JDBC extension
with WLS pooling. I also had.
In this case BEA recommends to use dangerous
method getVendorConnection() which exposes
the physical connection object to your code.
Yes it's really dangerous because of unsafe usage may breaks
WLS pooled connection(s).
Moreover, this practice will make your JDBC code
unportable (your JDBC code in addition to Oracle dependence
became Weblogic dependent):
void doSmth() {
Connection con = ...;
Connection vCon = ((WLConnection)con).getVendorConnection();
// + mess of usage con in one places and vCon in others
// (where Oracle extensions are needed)
// !Don't forget to don't close vCon!
Sux.
I found the workaround.
Introduction
============
Yes the real cause of ClassCastException is that
in depth of Oracle driver the casting
to class oracle.jdbc.driver.OracleConnection
(not to interface oracle.jdbc.OracleConnection)
is performed.
Someone can say that this is bug or pure desing.
Weblogic pooled connection provide dynamic
implementation for all public interfaces
which real physical (wrapped) connection object implements.
Great feature!
But I guess that all interface methods implemented
by simple call-delegation to physical (wrapped) connection object.
In case of oracle.jdbc.OracleConnection interface
this approach doesn't work for at least one its method:
public OracleConnection unwrap()
WLS pooled connection shoudn't implement this method by
delegation to physical connection object BUT should
return physical connection object itself!
// Wrong implementation of unwrap()
// delegation is used
public OracleConnection unwrap() {
return physicalConnection.unwrap();
// Right implementation of unwrap()
// physical connection returned
public OracleConnection unwrap() {
return physicalConnection;
Workaround
==========
1. Develop your own OracleConnection wrapper class:
import oracle.jdbc.OracleConnection;
import weblogic.jdbc.extensions.WLConnection;
public class MyOracleConnectionImpl implements OracleConnection {
private OracleConnection con;
public MyOracleConnectionImpl(OracleConnection connection)
throws SQLException
this.con = connection;
public OracleConnection unwrap() {
return (OracleConnection)
((WLConnection)con).getVendorConnection();
/* Implement all other methods by delegation to con object */
2. Don't get Connections directly from DataSource --
develop your own simple (may be static) utility
class which retrives Connections from dataSource
and returns them wrapped into your MyOracleConnectionImpl
to your code from some method:
puclic abstract class MyConnectionSource {
public static Connection getConnection() {
Connection con = // get it from DataSource
return new MyOracleConnectionImpl((OracleConnection)con);
3. Add attribute RemoveInfectedConnectionsEnabled="false"
to definition of your JDBCConnectionPool within config.xml
You may do it because of you `safely` use vendorConnection --
you don't expose it to application code.
4. Enjoy the Oracle JDBC extensions in your code!
Example:
Connection con = MyConnectionSource.getConnection;
ArrayDescriptor add =
ArrayDescriptor.createDescriptor("your_type", con);
Hope it helps to someone.

Updating a CLOB using the JDBC 8.1.6 driver
I have two issues on which comments are welcome. ( I am using the thin driver )
1. Using the JDBC 2.0 way of updating a CLOB
is not possible as the manuals state that
this can cause "serious corruption".
2. Using the Oracle specific way ( using
Oracle specific classes ), it looks like
I cant update a CLOB column without
retrieving it first.
It looks like I need a handle to the CLOB
in a CLOB object before I can update it.
This is very frustrating because in my application, we retrieve objects from a database, may keep the object in memory for
a long time and then update the object from
the in-memory copy. If I had to use the Oracle specific way of updating clobs, every
time I need to update a clob, I need to
retrieve the clob first and then update it
which runs contrary to handling of other types of columns.
nullAh. I think you're referring to:
In the implementation of the Oracle JDBC drivers, this functionality is supported only for a configuration using an 8.1.6 database and 8.1.6 JDBC OCI driver. Do not use this functionality for any other configuration, as data corruption can result.
yeah, that's about what I'm seeing. Anything over 4k blows up. Hopefully the 8.1.6 driver + DBMS will fix these problems.
Has anyone out there tried it? Can we use the GetClob/GetBlob, or even the getXXXStream() methods in 8.1.6 against CLOB/BLOB columns
? I sure hope so. SQL Server and mySQL :-)drivers can both handle it. -
Advanced Queue - using the JDBC connection
Advanced Queue using the JDBC connection gives us AN ERROR WHEN SENDING 32K QUEUES
Is it true that RAW datatypes using the Java AQ API do indeed have a limit of 32K in 8.1.6.
The workaround is to use the Java AQ API with Object payloads (BLOBs) to get around the problem.
Has anyone used any other solution ?
Thanks
nullThere's a JDBC forum that's probably more germane to this question-- I'd suggest reposting it there.

Using Oracle8 JDBC Drivers with WebLogic 5.1
We are currently using the BEA WebLogic 5.1 application server and Oracle 8.0.4. We are using the JDBC OCI driver that came out-of-the-box with the WebLogic software. However, we would like to use the driver developed by Oracle, instead.
Does the Oracle8 JDBC driver (both type 2 and type 4) interoperate with WebLogic 5.1? If not, what are the problems that prohibit them being used together?
Thanks... Steve BurschSummarizing from previous threads on this forum (I have not run this configuration myself):
The main issue is that you will not be able to use Oracle-specific functionality from the Oracle driver.
This includes all types in oracle.sql, or any APIs on oracle.jdbc.driver.OracleXxxx classes, or JPublisher-generated wrappers for SQL Object Types, collections, or REFs.
Also, since Oracle does not support side-channel result sets, but requires explicit REF CURSOR out parameters from stored procedures/functions, you will not be able to return REF CURSORs to the client, from stored proedures or functions - the getCursor() API that is required is Oracle-specific and not part of JDBC.
As long as you limit yourself strictly to standard JDBC types, and do not require the return of result sets from the server, you should probably be fine. -
Directory Proxy JDBC object class
Hi all,
I'm connecting my proxy to an oracle database. When we create the jdbc object class using "dpconf" do we have to use an objectclass that already exists in the ldap directory?
for instance:
dpconf create-jdbc-object-class –v -e -h <hostname> -p 1389 -D "cn=proxy manager" -w /pw_file <my jdbc view> *<??objectclass?? >* <jdbc table> <dn>
I'm not understanding what they mean by mapping to an objectclass in ldap.
Any help or examples appreciated!!
Thanks
V.A JDBC object class maps an LDAP object class to one or more relational database tables. A JDBC object class works in a similar way to a join data view (see Join Data Views). Just as a join data view has primary and secondary source data views, a JDBC object class can obtain its information from more than one table. One table must be defined as the primary table, and additional tables, if they exist, are defined as secondary tables. The primary table controls the list of entries and additional information on these entries is extracted from the secondary tables.
When you define a JDBC object class, e.g person, you must specify the following operands:
The name of the JDBC data view to which this object class is attached.
The name of the JDBC object class, e.g person
The primary JDBC table from which the object class will obtain its list of entries, e,g USER_TABLE
A DN pattern that controls how DNs are constructed in the data view, e.g. cn
Optionally, one or more secondary JDBC tables.

Creating a LOV by using a Command Object
Hello All,
I have a report that's driven by a parameterized sproc, which is a year parameter. However, we have a table that I would like to use in my object command to populate this parameter with the values from the select statement to enforce consistency. A new year is inserted into to this table yearly by another process, which would keep me from having to go into a static list to update the year options yearly.
I've created the command object and saved it to the repository, but I can't figure out how to associate it to the report as the parameter.
Can anyone point me in the right direction?
Thanks in advance.hi DevinM,
two choices:
A) add the Command to your report
1) you can add the Command to your report...don't link it to any tables though...you'll get a "Generally not supported error" but you can ignore it for this test
2) now in your prompt you will have the Command available for the dynamic values
3) check that the number of records on your report remains the same as before...it should...any test i have run on this is aok
B) create a Business View
1) go into the Business View Manager and create a business view from the data foundation up
2) once you've got the business view built you can create an LOV from there which is available to your current report and all other reports

How can I use a COM object that does not have a type library?
Hello,
I've created a com server in python for which I do not have a type library. I am able to call functions for this application in Python, TCL, I'm sure VB, etc. without the type library.
Must I have a type library registered to use this COM object with Labview? I was hoping I could simply supply the name to the refnum (or the GUID) then call functions by passings strings to the invoke node. This does not seem to be possible - am I missing something?
In the event that I cannot use a com server without a type library. Any recommendataions on how to create one? I'm wondering if I can use the same GUID and create a shell in LabWindows which generates the IDL/TBD file I need for Labview to see my
com server.
Any help is greatly appreciated.

Yes that is true. LabVIEW needs that to configure the Property and
Methode Nodes correctly. Otherwise it would need to have a special
Property and Method Node with a configuration dialog similar to the Call
Library Node, but a LOT more complicated. Not sure many people could
make use of that, and it would be a very tiring experience trying to get
things setup in that way, by going through the edit, test, and crash
cycle over and over again.
