JDBC Active Connection count issue- Current row null issue

In our weblogic conse 10.3.5, the max connection capacity is set to 25, however when we start using the application , over a small period of time the current active connection count increases more than 25 like 30,55, 85 etc .. How is this possible? . Once the number of active connection count goes above the max connection capacity, our application behaves weirdly, some time for some users the current row return null and as a result we get Null pointer exception. we are using Jdev 11.1.2.1 and the application was migrated from 10g. The AM configuration is the default one as specified in most docs or when we create a new application module. Could you guys help us out.

How many concurrent users do you have? Are you opening database connections manually in the application code? If so, are you closing these connections when done?

Issue in getting current row value using getCurrent Value

Issue:When I call ththe method executeSearchVO from controller class
with Row row = personalActionSearchVO.first();
I am getting the corresponding value.
but my requirement is I have multiple record , If i press action on any of the record, I need to read SITName value for the particular record and need to pass it as parameter to other pager(i mean If i select any record, I need to get corresponding value in the attribute for the record.)
if i comment personalActionSearchVO.first(); i am getting null pointer exception.
Pl. helpme how to get current row instead of first row always.
AMIMPL Clause

row = personalActionSearchVO.getFirstFilteredRow("action","1");
Row masterRow = row;
personalActionSearchVO.setCurrentRow(masterRow);

Timo,
I am new to Jdevloper. I will explain the issue in detail.
Version: Oracle 9i Jdeveloper
I have a query page with multiple records. when I perform action , I need to pass 2 parameters from query screen to my actual page.
1 parameter is Login person Id,. Now the issue is with getting current value for 2nd paramenter. 2nd Parameter will be changed depends upon record i am choosing in my query page: column is : Information Name.
when I use getcurrentrow , I am getting null pointer exception.
My controller class when I click action button :
if("action".equals(pageContext.getParameter(EVENT_PARAM)) )
Serializable methodParams[] = {pageContext.getEmployeeId()+""};
applicationModule.invokeMethod("executeSearchVO1",methodParams);
{color:#993300}
// Here I need to get InformationName value based on the record I am choosing{color}
HashMap hashMap = new HashMap(2);
hashMap.put("XXHRPersonId", pageContext.getParameter("XXHRPersonId"));
// hashMap.put("InformationName", methodParams);
pageContext.forwardImmediately(
"OA.jsp?page=/xxhr/oracle/apps/xxhr/selfservice/personalaction/webui/XXHRPersonalActionPG",
null,
OAWebBeanConstants.KEEP_MENU_CONTEXT,
null,
hashMap,
true, // Retain AM

my AMIMPL Clause :
I am just pasting whatever I have tried. Pl. suggest me If my code is wrong.
*{color:#993300}I need to get current row information value from the below method*
*{color}*
public void executeSearchVO1(String loginPersonId)

System.out.println("Row count "+personalActionSearchVO.getRowCount());
// Row row = personalActionSearchVO.first();
Row row = personalActionSearchVO.getCurrentRow();
System.out.println("Informaton Name "+row.getAttribute("InformationName");
In this , If i initialzie with Row row = personalActionSearchVO.first();I am able to get value for my column Information Name.
whereas, if I use directly Row row = personalActionSearchVO.getCurrentRow();, i am getting null pointer exception.
Pl. let me know how to get current row value for Information Name.
Looking for the reply at the earliest.

Oracle 8i jdbc/Tomcat connection issues

Tomcat 4.1.8
Oracle 8i JDBC Driver
I have been able to create the DataSource as a global resource and as a local resource inside the context of the application.
The code hangs when it attempts to create a connection. I have been able to connect to the database and perform the necessary query in a standalone application to ensure that I actually can connect.
JSP Code:
<html>
<head>
<title>VTW App</title>
</head>
<body>
<%
vtw.VTWApp tst = new vtw.VTWApp();
tst.init();
%>
<h2>Results</h2>
<%= tst.getList() %>
</body>
</html>
Java Code (Class called by JSP):
package vtw;
import javax.naming.*;
import javax.sql.*;
import java.sql.*;
public class VTWApp {
String list = "EMPTY";
public void init() {
try{
Context ctx = new InitialContext();
if(ctx == null )
throw new Exception("Boom - No Context");
System.out.println("Context Created ...");
DataSource ds =
(DataSource)ctx.lookup(

}

I figured out the issue ...
In the server.xml file the resource & resource params needed to be modified..
1. Set type to oracle.jdbc.pool.OracleDataSource
2. Set factory to oracle.jdbc.pool.OracleDataSourceFactory
3. In the Java code cast the context lookup to an OracleDataSource instead of a java.sql.DataSource
Oracles DataSource does not subclass the jdbc DataSource for its OracleDataSource class everything works fine now.

Current Row is null in AM method from VO instance exposed on Nested AM

Hello,
My Jdev version is 11.1.1.6.0 [Build JDEVADF_11.1.1.6.0_GENERIC_111205.1733.6192.1]
I have a very simple use case and that is to access the current row in AM method.
This works well when VO is directly exposed on Root AM but does not work when VO is exposed on nested AM except when taskflow transaction type is "No Controller Transaction".
Steps to reproduce:
Model side:
1. Create a simple entity based on say Employee table
2. Create a VO based on this entity
3. Create a child AM and expose this VO on it
4. Create a method just to get the current row from the VO exposed on this child AM
5. Expose the method on child AM to make it available on client side
6. Create a root AM and expose the child AM on it
View side:
1. Create employee.jsff showing data from employee VO
2. Drag and drop child AM's method as ADF Button on employee.jsff
3. Create a bounded taskflow containing simple view activity referring to employee.jsff
4. Set the transaction type on taskflow to anything other than "No Controller Transaction". (I noticed that sharing of data control does not matter. It works with "No Controller Transaction" with both settings and does not work with others when checked/un-checked)
5. Create main.jspx and drag-drop bounded taskflow here.
Run/Debug the application and check the current row in child AM method using the button on employee.jsff. Current row is retrieved as NULL.
Is it supposed to behave like this?
What is affecting the current row when transaction type is other than "No Controller Transaction"?
As I mentioned earlier, this works well with other transaction types when VO is directly exposed on Root AM.
Thanks,
Jai

Hi Jaya,
You want to catch Flexfield values?
Try below code for catch value.
OAApplicationModule am = pageContext.getApplicationModule(webBean);
if (pageContext.getParameter("queryBtn")!= null)
OADescriptiveFlexBean dfb = (OADescriptiveFlexBean)webBean.findChildRecursive("flexDFF"); //get the DFF bean
OAWebBean dffbean = (OAWebBean)dfb.findChildRecursive("flexDFF0"); //get the field that applies to the attribute1 column that is being rendered
OAMessageStyledTextBean Stylebean = (OAMessageStyledTextBean)dffbean;
String dtlsItem = (String)Stylebean.getText(pageContext);

sir have this error so what can i do The SIM card that you currently have installed in this iPhone is from a carrier that is not supported under the activation policy that is currently assigned by the activation server. This is not a hardware issue with the iPhone. Please insert another SIM card from a supported carrier or request that this iPhone be unlocked by your carrier. Please contact Apple for more information.

It looks like the iPhone is locked to a carrier that is not the one you are trying to use.
You need to determine which carrier it is locked to and then contact them to see if they are willing to authorise the unlocking of your iPhone. As ManSinha mentioned, many carriers will only authorised the unlock if requested by the customer who had the contract with them for this iPhone.
Remember that only the carrier who owns the lock on your Iphone can authorise Apple to unlock the iPhone in their servers. You need to contact the carrier or have the previous owner of the iPhone request the unlocking.

Active repository connections count.

Hello Guys,
I am using SAP MDM 7.1.
Can anybody let me know how we can count the number of active connections on any particular repository at any given time.
Is there any way to count it apart from doing it manually from Admin -> Connections.
Best Regards,
Syed.

Hi,
As such in MDM No standard functional available but you can acheive as follow
1. using MDM Java API
2. Right clicking on repository and select unload repository immediate will open popup window
with warning message number user logged and to unload repository
Thanks,

Issue in finding the current row

I am rendering rows of a VO using an iterator component. One of the component I am rendering is a declarative component created by me.
In this component there is a clickable link on which i can write any method to achieve desired functionality.
Since, iterator is used so the current row is set to the last row. Now on clicking the link in the declarative component i need to do some operation based on the current row (pk of that row). So, how to find the current row id?
Note: If it would be a simple adf component like a commandLink i could have inserted a setServerListener inside it and could have put the id in to requestScope to access it. But as this is the declarative component in which i cannot create a serverListener so I am looking for some other solution.

Hi john,
My table have the selection listener.
Thanks in advance

Losing the current row without doing anything

I using 10g and my page have a VOR (viewobject readonly) to control form data but...
I'm losing several times the current row ... for example I put this code in a button:
public String clickAction() {
AdminUCAtoCartorarioAMImpl am = null;
try {
am = ( AdminUCAtoCartorarioAMImpl )super.getApplicationModule( "AdminUCAtoCartorarioAMDataControl" );
am.getAmbienteEscaninhoVOR().getCurrentRow(); //Here, sometimes brings me null.
} catch (Exception e) {
e.printStackTrace();
return null;
}

User,
You give us the symptom of the problem, but
I'm losing several times the current rowdoesn't help anyone to help you pinpoint what might be the cause. Under what circumstances does the current row come across as null? Are you manually iterating through the VO's row set somewhere? What happens before the current row is "lost?" What specific version (your tag indicates 10g, but specifically which version) of JDeveloper/ADF are you using? Does this occur only when deployed, or does it occur when running in the embedded OC4J.
One thing for you to try... if it occurs "sometimes," seemingly randomly under load, try turning off Application Module Pooling and re-test. If it occurs every time with pooling turned off, you are likely seeing some issue related to passivation/activation - which is why it would be critical to mention the exact version; there are known issues with specific versions, and there are patches available.

Hi,
I guess you have check this with "show conn count" or "show conn" commands on the ASA?
Ofcourse the first thing that comes to mind is that its somehow adding up the connection count of both ASA units. Though it shouldnt do this to my knowledge. You should just see almost equal amount of connections on both units. Both Primary and Secondary.
Have you tried to check if there is any host on your local network that would be taking alot of connections? Maybe somethings happened at the same time (even though it might not be likely)
Have you noticed any performance issues/problem after this upgrade to a A/S ASA pair?

Crystal report returning duplicate rows - Linking issue?

Hello,
I know this is a commonly brought up issue - that duplicate rows are returned in Crystal reports for various reasons. In a lot of instances, where it's only a single row of data per case that I'm looking for, I'll move them to their own group. But that solution doesn't work here.
The tables and links used in the simple report I have are illustrated in the attached "Report Database Expert Links.jpg" file, and the conditions and report fields required as as follows:
Select Expert conditions:
{CLAIM_PERIODS.CPE_START_DATE} < Today and
{CLAIM_PERIODS.CPE_END_DATE} > Today and
{CLAIM_ROLES.CRO_START_DATE} < Today and
IsNull({CLAIM_ROLES.CRO_END_DATE})
Report Design fields (in Details section):
CLAIMS.CLA_REFNO, CLAIM_ROLES.CRT_CODE, PARTIES.PAR_PER_FORENAME, PARTIES.PAR_PER_SURNAME
So what this report is to do:
It looks for benefit claims which are live (have a CLAIM_PERIODS.CPE_START_DATE prior to today, and CLAIM_PERIODS.CPE_END_DATE after today), and for these claims gives a breakdown of all people in the household (everyone associated with that claim, where CLAIM_ROLES.START DATE is prior to today, and end date is null - to pick out those who are currently active in the household).
This works fine otherwise, but the issue is that each live claim can have either one or two rows present in CLAIM_PARTS and CLAIM_PERIODS (so could satisfy my first two conditions twice). For claims with only a single claim part active, I get each household member listed once. But when they have two claim parts active, I get eveyone listed twice.
Is there a way - either in how I'm linking the tables up, or how I'm arranging the report design, that I can have every household member only appear once no matter how many related rows there are in CLAIM_PARTS and CLAIM_PERIODS?
Many thanks in advance,
Sami
P.S. I don't seem to be allowed to attache image files to my post, but have embedded the content instead:

Thank you very much Don - this is a feature I wasn't aware of previously, and is a big step in the right direction for me. Really useful.
In the report mentioned, this sort of works. It works very well on individual fields - so I could just "Suppress If Duplicated" on the forename and then remove duplicates on that column when exported to Excel (or simply bring in a unique field such as the party reference number and do likewise).
However, is there a way to get Crystal to do this for me? So to suppress the whole line based on whether or not I'm suppressing this one field?
Just applying "Suppress If Duplicated" to all fields at once seems to have slightly unpredictable behaviour - not suppressing every field in the row. So I experimented a bit with using the "Suppress" tick to do this, then applying a formula to it. But the closest I can get for the formula is something like:
- {PARTIES.PAR_PER_FORENAME} = previous({PARTIES.PAR_PER_FORENAME}) and
{PARTIES.PAR_PER_SURNAME} = previous({PARTIES.PAR_PER_SURNAME}) and
Which will only compare the current row with previous. Is there a way to do the same comparison but with all previous rows?

Java.sql.SQLException: No current row in the ResultSet

Hi All,
I use JTDS 1.2.
I get the following error:
java.sql.SQLException: No current row in the ResultSet.
when I run the following code:
     public void QueryToCust(){
          String username = "sa";
          String password = "";
          String url = "jdbc:jtds:sqlserver://localhost:1433/OkyanusPINAR2006;tds=8.0";
          setSQLcode("select * from firma where kod='123'");
          try{
               Class.forName("net.sourceforge.jtds.jdbc.Driver");
          } catch (Exception e){
               setErrMsg(e.toString() + " cannot register class.");
               return;
          Statement stmt = null;
          Connection con = null;
          try{
               con = DriverManager.getConnection(url,username,password);
          } catch (Exception e){
               setErrMsg(e.toString() + " cannot connection!");
               return;
          try{
               stmt = con.createStatement();
               ResultSet rs = stmt.executeQuery(sqlCode);
               if(rs != null){
                    String name = new String(rs.getString("name"));
                    setCustName(name);
          rs.close();
               con.close();
          } catch (Exception e){
               setErrMsg(e.toString());
               return;
          setErrMsg("jdbc: No error!");
     }This sql code running with msSQL Enterprise Manager SQL tools return to row. But can not run it in java! Why?

you need to call
rs.next();
