Hello,
Does anyone know i can configure Hibernate to connect automatically to an Oracle base in the case of a cut network.
Thanks,

what is dead locks with oracle and wht is race condition wrt oracle

> And do you know what a race condition is all about?
It is a term used to indicate several processes attempting to use the same resource that is not capable of servicing all these at the same time. This could be due to the resource not being thread safe or implemented as a serialised resource.
It is often easy to look up definitions on Google. In the Google search field, type "define:race condition".

How can i make my java app auto reconnect to Oracle.

Scenario:
when i am working with my java app if suddenly Oracle server connection unplugged. Then i got some problems regarding database.
When they replugged the connection, i need to restart my app again. Then it works fine.
Question:
When the database is replugged or restarted, then how can i reconnect to the DB automatically with out restart my app. Please letme know is there any auto reconnect process is there for Oracle.

If you want your application to reconnect, you would need to add logic that catches the exception that gets thrown when the connection is lost and tries to reconnect.

Auto Reconnection of Oracle Tuxedo 11.1.1.2.0, 64-bit to Oracle Data Base

Hi Dear,
We have Recently Migrated to Oracle Tuxedo 11.1.1.2.0 Running on RHEL 6.3 and connecting Oracle Data Base 11.0.2.0.
We are informed by the Oracle Tuxedo Support that This tuxedo version Automatically re-connects to the oracle database once the Data base is rebooted.
Because of the above impression we removed all our reconnection code from our applications.
But unfortunately the servers are not automatically re-connecting to Oracle DB.
Can you Please let us know, whether really this version automatically re-connects to Oracle DB??
If Yes, How?? I mean is there any specific configuration to be done on Tuxedo??
Thanks in Advance .... :)
Rgds,
Plaban

Plaban,
There are two ways to manage connections to Oracle Database (or any other XA compliant resource manager) with Tuxedo.
One way is to use the XA interface. This involves spcifying information about the resource manager in $TUXDIR/udataobj/RM, building TMS servers linked with the resource manager, using the "-r rmname" option on buildserver, and specifying the TMS server names and an OPENINFO string *GROUPS section of the UBBCONFIG file. When this option is chosen, application servers will not contain any logic to connect to or disconnect from the database and appllication servers will not contain any SQL statments to COMMIT WORK or ROLLBACK WORK. All of this will be managed by Tuxedo. If an XA call indicates that the resource manager is unavailable, Tuxedo will try to reconnect to the resource manager when subsequent tranasctional requests are received. (Note that if a server in an XA-associated group receives requests outside of transaction mode, then Tuxedo will not issue any XA calls and will not know if there are any problems with the database. You can specify AUTOTRAN=Y if you want to ensure that requests to certain services are processed in transaction mode.)
In releases prior to Tuxedo 11.1.1.2.0, it was necessary to set the TUXWA4ORACLE environment variable for this automatic reconnection to work when using Tuxedo with Oracle Database. (This was due to different interpretations of the XA standard back when BEA and Oracle were separate companies.) Starting with Release 11.1.1.2.0, it is no longer necessary to set TUXWA4ORACLE when using Oracle Database with Tuxedo.
There are also special considerations when using Tuxedo with Oracle Real Application Clusters, as described at http://docs.oracle.com/cd/E35855_01/tuxedo/docs12c/ads/adorac.html .
The other way to use Tuxedo with a database is to not use the XA interface and to manage connections to the database in the application. If this is done, then the application needs code to connect, disconnect, and reconnect to the database and to commit or rollback work where appropriate. If the XA interface is not used, then Tuxedo will not have any involvement with connection or reconnection to the database.

Ed

How do I set miminum # of connections for pool with Oracle and Tomcat?

Hi,
I can't seem to find any attribute to initialize the number of connections for my connection pool. Here is my current context.xml file under my /App1 directory:
<Context path="/App1" docBase="App1"
debug="5" reloadable="true" crossContext="true">
<Resource name="App1ConnectionPool" auth="Container"
type="oracle.jdbc.pool.OracleDataSource"
driverClassName="oracle.jdbc.driver.OracleDriver"
factory="oracle.jdbc.pool.OracleDataSourceFactory"
url="jdbc:oracle:thin:@127.0.0.1:1521:oddjob"
user="app1" password="app1" />
</Context>
I've been googling and reading forums, but haven't found a way to establish the minimum number of connections. I've tried all sorts of parameters like InitialLimit, MinLimit, MinActive, etc, with no success.
Here is some sample code that I am testing:
package web;
import oracle.jdbc.pool.OracleDataSource;
import oracle.jdbc.OracleConnection;
import javax.naming.*;
import java.sql.SQLException;
import java.sql.ResultSet;
import java.sql.Statement;
import java.util.Properties;
public class ConnectionPool {
String message = "Not Connected";
public void init() {
OracleConnection conn = null;
ResultSet rst = null;
Statement stmt = null;
try {
Context initContext = new InitialContext();
Context envContext = (Context) initContext.lookup("java:/comp/env");
OracleDataSource ds = (OracleDataSource) envContext.lookup("App1ConnectionPool");
message = "Here.";
     String user = ds.getUser();
if (envContext == null)
throw new Exception("Error: No Context");
if (ds == null)
throw new Exception("Error: No DataSource");
if (ds != null) {
message = "Trying to connect...";
conn = (OracleConnection) ds.getConnection();
Properties prop = new Properties();
prop.put("PROXY_USER_NAME", "adavey/xxx");
if (conn != null) {
message = "Got Connection " + conn.toString() + ", ";
          conn.openProxySession(OracleConnection.PROXYTYPE_USER_NAME,prop);
stmt = conn.createStatement();
rst = stmt.executeQuery("SELECT username, server from v$session where username is not null");
while (rst.next()) {
message = "DS User: " + user + "; DB User: " + rst.getString(1) + "; Server: " + rst.getString(2);
rst.close();
rst = null;
stmt.close();
stmt = null;
conn.close(); // Return to connection pool
conn = null; // Make sure we don't close it twice
} catch (Exception e) {
e.printStackTrace();
} finally {
// Always make sure result sets and statements are closed,
// and the connection is returned to the pool
if (rst != null) {
try {
rst.close();
} catch (SQLException e) {
rst = null;
if (stmt != null) {
try {
stmt.close();
} catch (SQLException e) {
stmt = null;
if (conn != null) {
try {
conn.close();
} catch (SQLException e) {
conn = null;
public String getMessage() {
return message;
I'm using a utility to repeatedly call a JSP page that uses this class and displays the message variable. This utility allows me to specify the number of concurrent web requests and an overall number of requests to try. While that is running, I look at V$SESSION in Oracle and occassionaly, I will see a brief entry for app1 or adavey depending on the timing of my query and how far along the code has processed in this example. So it seems that I am only using one connection at a time and not a true connection pool.
Is it possible that I need to use the oci driver instead of the thin driver? I've looked at the javadoc for oci and the OCIConnectionPool has a setPoolConfig method to set initial, min and max connections. However, it appears that this can only be set via Java code and not as a parameter in my context.xml resource file. If I have to set it each time I get a database connection, it seems like it sort of defeats the purpose of having Tomcat maintain the connection pool for me and that I need to implement my own connection pool. I'm a newbie to this technology so I really don't want to go this route.
Any advice on setting up a proper connection pool that works with Tomcat and Oracle proxy sessions would be greatly appreciated.
Thanks,
Alan

Well I did some more experiments and I am able to at least create a connection pool within my example code:
package web;
import oracle.jdbc.pool.OracleDataSource;
import oracle.jdbc.OracleConnection;
import javax.naming.*;
import java.sql.SQLException;
import java.sql.ResultSet;
import java.sql.Statement;
import java.util.Properties;
public class ConnectionPool {
String message = "Not Connected";
public void init() {
OracleConnection conn = null;
ResultSet rst = null;
Statement stmt = null;
try {
Context initContext = new InitialContext();
Context envContext = (Context) initContext.lookup("java:/comp/env");
OracleDataSource ds = (OracleDataSource) envContext.lookup("App1ConnectionPool");
message = "Here.";
     String user = ds.getUser();
if (envContext == null)
throw new Exception("Error: No Context");
if (ds == null)
throw new Exception("Error: No DataSource");
if (ds != null) {
message = "Trying to connect...";
boolean cache_enabled = ds.getConnectionCachingEnabled();
if (!cache_enabled){
ds.setConnectionCachingEnabled(true);
Properties cacheProps = new Properties();
cacheProps.put("InitialLimit","5");
     cacheProps.put("MinLimit","5");
cacheProps.put("MaxLimit","10");
ds.setConnectionCacheProperties(cacheProps);
          conn = (OracleConnection) ds.getConnection();
Properties prop = new Properties();
prop.put("PROXY_USER_NAME", "adavey/xyz");
if (conn != null) {
message = "Got Connection " + conn.toString() + ", ";
          conn.openProxySession(OracleConnection.PROXYTYPE_USER_NAME,prop);
stmt = conn.createStatement();
//rst = stmt.executeQuery("SELECT 'Success obtaining connection' FROM DUAL");
rst = stmt.executeQuery("SELECT user, SYS_CONTEXT ('USERENV', 'SESSION_USER') from dual");
while (rst.next()) {
message = "DS User: " + user + "; DB User: " + rst.getString(1) + "; sys_context: " + rst.getString(2);
message += "; Was cache enabled?: " + cache_enabled;
rst.close();
rst = null;
stmt.close();
stmt = null;
conn.close(OracleConnection.PROXY_SESSION); // Return to connection pool
conn = null; // Make sure we don't close it twice
} catch (Exception e) {
e.printStackTrace();
} finally {
// Always make sure result sets and statements are closed,
// and the connection is returned to the pool
if (rst != null) {
try {
rst.close();
} catch (SQLException e) {
rst = null;
if (stmt != null) {
try {
stmt.close();
} catch (SQLException e) {
stmt = null;
if (conn != null) {
try {
conn.close();
} catch (SQLException e) {
conn = null;
public String getMessage() {
return message;
In my context.xml file, I tried to specify the same Connection Cache Properties as attributes, but no luck:
<Context path="/App1" docBase="App1"
debug="5" reloadable="true" crossContext="true">
<Resource name="App1ConnectionPool" auth="Container"
type="oracle.jdbc.pool.OracleDataSource"
driverClassName="oracle.jdbc.OracleDriver"
factory="oracle.jdbc.pool.OracleDataSourceFactory"
url="jdbc:oracle:thin:@127.0.0.1:1521:oddjob"
user="app1" password="app1"
ConnectionCachingEnabled="1" MinLimit="5" MaxLimit="20"/>
</Context>
These attributes seemed to have no effect:
ConnectionCachingEnabled="1" ; also tried "true"
MinLimit="5"
MaxLimit="20"
So basically if I could find some way to get these attributes set within the context.xml file instead of my code, I would be a happy developer :-)
Oh well, it's almost Miller time here on the east coast. Maybe a few beers will help me find the solution I'm looking for.

Installation of CRM 2007 in Windows with oracle and cluster environment

Dear Experts,
We are about to start the installation of CRM 2007 (ABAP+JAVA) with
Oracle 10g on Windows x64 in cluster environment. In the SAPINST dialog
box under High availability option, I could see installation options like ASCS
Instance, SCS Instance, First MSCS node, Database Instance, Additional
MSCS Node, Enqueue Replication Server, Central Instance and Dialog
Instance.
I have gone through the installation guide. I have below queries
regarding the same. Can you please clarify the same
1) Our requirement is we want to have an ACTIVE-ACTIVE cluster setup
with sap service running in Node A and Database running in Node B. Can
we have this setup in ABAP+JAVA setup
2) Also,in the SAPINST dialog box as said above except last two
(Central and Dialoge instance) as per standard installation guide are
to be installed in shared drives as per the requirement. But, central
and dialog are said to be installed locally on any one node in MSCS or
in separate server. As per my understanding Dialog instance will be
used for load balancing which we do not require now. Hence I feel this
is optional in our case. Where as Central Instance I am not able to
understand why this option is for? Is it mandatory to be installed or optional. If
so, when I installed it in one of the MSCS node the incase of failover
how does it effect the system. As per my understanding ASCS and SCS
comprise central instance.
Please clarify and thanks in advance.

Sharath Babu M

I am following as per the standard installation guide.

I have read about this issue in the newsgroup and I know it seems to be a bug
in Oracle Driver.
So, as a workaround, I'm trying to use the Oracle's prepared statement cache features
in order to avoid creations of new statements for each query. I noticed that the
WebLogic prepared statement cache does not work properly, because I put a value
of 10 but when inspecting with WLShell it haven't any hit in the statement cache.
In order to use Oracle's prepared statement cache I have to enable it in the physical
connection, but I don't found in weblogic.jar the class weblogic.jdbc.extensions.WLConnection
which have the method getVendorConnection. In the documentation available at http://edocs.beasys.com/wls/docs61/javadocs/index.html
there is a reference to that class and it haven't any notice since which service
pack it becomes available.
So, is there any way to obtain the physical connection?
Can anybody help me about any of these problems??
Thanks in advance.
Jesús.

The line of code that brings up this exception is:
multiReq = new
= new MultipartRequest((ServletRequest)request,
"c:\\temp", 10485760);
try this: MultipartRequest multiReq = new MultipartRequest((ServletRequest)request,
"c:\\temp", 10485760);
(not sure if that is the problem or not..)

Server Issue with Oracle and ASP Connection

We got a new server and are trying to set it up with Oracle Client to allow our web application to connect to the database server. We are getting connection errors, but on the old server, it works fine. We have Windows 2003 and IIS 6.0 on the new server and Win2K and IIS 5.0 on the old server and it's Oracle 8i. Here is the error...
Err.description=Oracle client and networking components were not found. These components are supplied by Oracle Corporation and are part of the Oracle Version 7.3.3 or later client software installation. Provider is unable to function until these components are installed.
Err.number=-2147467259
... We have the client installed, so not sure what to do from this point on. Can it be some type of a sharing issue, or network firewall issue?

Have you granted the IIS user read & execute access to the %ORACLE_HOME% directory and subdirectories?

Must I use spring Framework with JSF2 and Hibernate?

Hi all,
I'm starting to develop a web portal and I would use JSF2 and Hibernate.
Now I don't know JSF2 so I searched some tutorial.
I found a tutorial on JSF2 that seems very complete but in this tutorial I found a section where the author use Hibernate for the "model section", JSF2 for the "view section" and Spring for the "controller section"!
Now I have a doubt, can I develop a web portal without Spring MVC or I can't develop any controller's component with JSF2?
Thank you for your replies!

For Ram, do you mean that JSF2 isn't a MVC framework with your reply?
For Kayaman, the author did some examples how implements some frameworks with JSF2 and he do 3 examples:
1) JSF2 and JDBC;
2) JSF2 and Spring;
3) JSF2, Spring and Hibernate!
However, after this thread, I found a forum in linked to the tutorial and I asked why they use JSF2 and Spring together! Now Im waiting the answer!
For Gimbla2: well, I'm novice on JSF2 but I develop for some years with ADF and JBO framework!
You are right to tell me "On the official sites you can find all informations" but I would know some things from some one that used both frameworks!
Thanks again to all.

How to work with oracle and active directory...

Hi,
Can somebody let me know how do i configure active directory with oracle 10g?
I am trying to do this using configuration wizard but fields are grayed out for me to proceed. It also shows me to prepare active directory to work with oracle first.
How do i do that?
Can someone let me know the steps to do so?
Regards
Vikas

Depends on what you want to achieve?
Usually when you want Enterprise Users (users that are managed by a directory instead of a schema) you will perform other steps than in a scenario where you need some attributes from the AD.

Connection Problem with Oracle and Tomcat.

I was able to enter Oracle using scott/tiger when I did not connect Tomcat.But when I connect tomcat I am unable to log onto Oracle.
When I logged to the database then I tried to start the Tomcat but it gave an exception.So I went to the task manager and ended the running processes like isqlplus.exe, oracle.exe, tomcat.exe, apache.exe.When I ended all the processes except oracle.exe, tomcat gave an exception. But when I ended oracle.exe Tomcat started working but Oracle stopped working. I don't know what the problem is.
Can anyone help me out?
Thanks,
Sravanthi.

> Can anyone help me out?
Yeah sure. Is there a SQL or PL/SQL related question in there.. somewhere.. hiding away?
After all, you do realise that the name of this forum is SQL and PL/SQL and that it deals with the SQL and PL/SQL languages in the Oracle server.. right?

Jasper report with Struts2 and hibernate.

A lot of problems with Oracle and ASP

Hi, i need to develop a system using ASP and Oracle. I should have started this about 3 weeks ago and I can't in any way connect these 2 technologies.
First, I tried through ODBC and it could not be done.
Next, I tried through OLEDB and when I thought that the problem was found...
set objSessao = Server.CreateObject("OracleInProcServer.XOraSession")
set objConexao = OraSession.DbOpenDatabase("mozart", "jacto_revendas/bolinha",cint(0))
These 2 lines seems to be correct, then I had the error "access to object denied", and I read in some forum that it was because some DLLs of %oracle_home%\bin were without permission. I scanned all of them, and gave full access. OK. Then, an error ASP 0177 (error accessing DLL library) appeared and I could not find solution over the Internet.
And the incredible part is that the error only happens as soon as I start the OS... the second time I try, the script stops and does not show any errors or results... the page keeps processing without an end.
Please, I can't find anyone that can help me... you are my last hope...
thanks
Mozart

I agree with your suggestion about needing more documentation for APS.NET & Oracle connections. And so the next question is who knows where to find such docs? I've scoured the Oracle & MSDN sites, and have found nothing addressing these permission problems -- at least nothing that fixes the problem. See my recent postings about "access denied exceptions". I've been trying for several weeks to get it fixed, w/o success although I think I'm getting closer & just about to give the ASPNET user total control over EVERYTHING in the oracle home directory tree.

Constant home wifi disconnect/reconnect with GS3 and GS4

I've been having terrible trouble with my previous Galaxy S3 and my new Galaxy S4 on my home wifi network. They CONSTANTLY disconnect and reconnect. Sometimes it can happen 2 or 3 times in 1 minute, and sometimes it won't happen for 5 or 6 minutes, but then it will happen and it will happen 2 or 3 times in rapid succession. This is really irritating when I'm viewing a web page and it has to reload EVERY time the disconnect/reconnect happens.
What can I do to keep my GS4 from doing this?
I have the Verizon GT704WGB DSL modem/wireless router.
I have my laptop and my Kindle Fire HD connected via wifi to this router, and they never experience the problem, only my GS3 and GS4.
Any help in this matter would be greatly appreciated.

Hi TR_Young,
We're here to help! Have you tried resetting your router? Do you know if your Wi-Fi router needs to be updated? I understand wanting the phones to stay connected to Wi-Fi. Do the phones having problems have trouble on other Wi-Fi networks? We look forward to hearing from you about these details.

Parent Child Hierarchy with FDS and Hibernate

I know my chances of getting heard here are slim, but I am at
a dead end, so here goes.
I have a four level hierarchy of objects
PlanPoint
....UserScenario
........Scenario
............Competitor
which have bi-directional one-to-many relationships between
them.
I have made sure that my hibernate mappings and FDS
destination are matched and I definitely need to have managed
associations as the graph of objects will grow large in my
application (and besides, it is good development practice). So I
have a fully formed project (or at least I think I do) and I get a
duplicate object error.
Right at the bottom I have an alternative that I have tried
which gives a different error.
Here is a snippet from my log... it picks up just after the

Hi,
thanks for the reply it was very helpful. I came to pretty
much the same conclusion and started on the path of a re-write of
the hibernate assembler myself. As far as I can tell the Hibernate
Assembler is a Java Assembler, so there didn't seem much difference
to me between fixing that one and writing another one. Adobe ship
the code.
Bit of a cheeky request, but I don't suppose you would be
willing to share your assembler layer so I have a template against
which to work? Biggest problem with this sort of activity is a lack
of examples which makes it very slow going and largely trial and
error.
If you would like to know more about our application I will
provide contact details so we can discuss.
Simon
PS Jeff Vroom posted a reply saying that the Adobe Hibernate
Assembler didn't work properly with hierarchical data (which I
imagine is every real application in the world), personally I think
