How to collect DB stats from 10g database

Hi All,
We have a production Oracle 10.1.0.5.0 database. We are facing performance issue in the application side. So we are in process of analysing the performance issues in both database and application side. Application vendor is asking for DB stats of the primary schema.
I dont know anything about database performance tuning activities like collecting DB stats, using Statspacks etc...
Kindly help me to understand about DB stats and what is the best way collect the required DB statistics information.
Thanks in advance.

Workspace to parse SQL statements from multiple database schema's

Hi ,
When go through the following link of workspace admin user :
Home>HTML DB Workspace Administration>Manage Services>Schema Reports>Workspace Schemas there I saw "Your workspace has the privilege to parse SQL statements using the following database schemas. Note that the terms database schema and database user can be used interchangeably.
" at the right pane.
So how can i make my workspace to parse SQL statements from multiple database schema's ?That must be listed there .But i have only one schema in view ? Can i make it multiple ?If then How ?
Anybody have an idea ?

Assign as many schemas to your workspace as you want using the administration app. Read about it in the doc.

How to get the data from mysql database which is being accessed by a PHP application and process the data locally in adobe air application and finally commit the changes back in to mysql database through the PHP application.

How to get the data from mysql database which is being accessed by a PHP application and process the data locally in adobe air application and finally commit the changes back in to mysql database through the PHP application.

If the data is on a remote server (for example, PHP running on a web server, talking to a MySQL server) then you do this in an AIR application the same way you would do it with any Flex application (or ajax application, if you're building your AIR app in HTML/JS).
That's a broad answer, but in fact there are lots of ways to communicate between Flex and PHP. The most common and best in most cases is to use AMFPHP (http://amfphp.org/) or the new ZEND AMF support in the Zend Framework.
This page is a good starting point for learning about Flex and PHP communication:
http://www.adobe.com/devnet/flex/flex_php.html
Also, in Flash Builder 4 they've added a lot of remote-data-connection functionality, including a lot that's designed for PHP. Take a look at the Flash Builder 4 public beta for more on that: http://labs.adobe.com/technologies/flashbuilder4/

How to I convert data from oracle database into excel sheet

how to I convert data from oracle database into excel sheet.
I need to import columns and there datas from oracle database to microsoft excel sheet.
Please let me know the different ways for doing this.
Thanks.

asktom.oracle.com has an excellent article on writing a PL/SQL procedure that dumps data to an Excel spreadsheet-- search for 'Excel' and it'll come up.
You can also use your favorite connection protocol (ODBC, OLE DB, etc) to connect from Excel to Oracle and pull the data out that way.

How to search a string from the database?

how to search a string from the database? starting with some character

If you're trying to do this in a SELECT, you can use the LIKE verb in your WHERE clause.
Here's an Example
SELECT obj_name FROM tadir
    INTO prog
    WHERE pgmid = 'R3TR'
      AND object = 'PROG'
      AND obj_name LIKE 'Z%'.
In this case it will select every row that obj_name starts with Z.
If you wanted to find every row that the field obj_name contains say... 'WIN' you use LIKE '%WIN%'.

How to select alternate entries from the database table

Hi Experts,
can u help me, how to select alternate entries from the database table.
Thanks

As there is no concept of sequence (unless there is a field specifically included for the purpose), there is no meaning to "alternate" records.
What table do you have in mind, what data does it hold, and why do you want alternate records?

How to access application state from stateless web service?

I have a beginner J2EE question. After reading through J2EE tutorial, I still don't know how to create an application that would run on J2EE server, and which would have a web service interface to other world, and which would have several threads running, which would connect to other enterprise applications via TCP? Because if I understand it correctly, web service requires a stateless session bean, which means that it can't access any stateleful session bean (except always create one and remove it instantly). So there seems to be no way to store application state and have running threads.
I'm asking this because .NET seems to have a very simple Application dictionary, which can save all application objects, including threads, and it is very easy to access this Application state from a stateless web service. Isn't there any similar functionality in J2EE? And if not, how it should be done in Java world then?
I guess that the Connector architecture could be the solution, but it is not documented in the tutorial.

There's nothing in the J2EE spec that says that you have to use Web Services. Web Services by definition are stateless.
If your requirements are that you have to use a session bean along with a Web Service, then the architecture needs to be rethought, because it doesn't seem to me that Web Services are what you want.
That said, you can use a hybrid. You can expose some of the functionality of your application as Web Services while the remaining is implemented in a classic J2EE type framework that is stateful.
I would also think that you could store your application state via entity beans. You could save and load them when the web service is accessed. An entity bean doesn't require a database... just some form of persistence (could be an XML file for instance).
You need to decide which components of J2EE make sense when and where.

How I can transfer data from the database into a variable (or array)?

I made my application according to the example (http://corlan.org/2009/06/12/working-in-flash-builder-4-with-flex-and-php/). Everything works fine. I changed one function to query the database - add the two parameters and get the value of the table in String format. A test operation shows that all is ok. If I want to display this value in the text area, I simply drag and drop service to this element in the design mode
(<s:TextArea x="153" y="435" id="nameText" text="{getDataMeanResult.lastResult[0].name}" width="296" height="89" />).
It also works fine, just a warning and encouraged to use ArrayCollection.getItemAt().
Now I want to send the value to a variable or array, but in both cases I get an error: TypeError: Error #1010: A term is undefined and has no properties..
How can I pass a value from the database into a variable? Thank you.
public var nameTemp:String;
getDataMeanResult.token = authors.getDataMean(arrayOfNumber[0], dir_id);
nameTemp = getDataMeanResult.lastResult[0].name;
public var nameArray:Array = new Array();
for (var i:uint=o; i<3; i++){
getDataMeanResult.token = authors.getDataMean(arrayOfNumber[i], dir_id);
nameArray[i] = getDataMeanResult.lastResult[0].name;
And how i can use syntax highlighting in this forum?

I have to go back to the discussion. The above example works fine when i want to get a single value of the database. But i need to pass an array and get an array, because i want to get at once all the values for all pictures tooltips. I rewrote the proposed Matt PHP-script and it works. However, i can not display the resulting array.
yep, it won't work for Arrays, you'll have to do something slightly more intelligent for them.
easiest way would be to get your PHP to generate XML, then read that into something like an ArrayList on your HTTPService result event (depends what you're doing with it).
for example, you could have the PHP generate XML such as:
<pictures>
     <location>test1.png</location>
     <location>test2.png</location>
     <location>test3.png</location>
     <location>test4.png</location>
     <location>test5.png</location>
     <location>test6.png</location>
</pictures>
then you'll read that in as the ResultEvent, and perform something like this on it
private var tempAC:ArrayList = new ArrayList
protected function getStuff_resultHandler(event:ResultEvent):void
    for each(var item:Object in event.result.pictures)
       var temp:String = (item.@location).toString();
       tempAC.addItem(temp);
in my example on cookies
http://www.mattlefevre.com/viewExample.php?tut=flash4PHP&proj=Using%20Cookies
you'll see an example of how to format an XML structure containing multiple values:
if($_COOKIE["firstName"])
        print "<stored>true</stored>";
        print "<userInfo>
                <firstName>".$_COOKIE["firstName"]."</firstName>
                <lastName>".$_COOKIE["lastName"]."</lastName>
                <userAge>".$_COOKIE["userAge"]."</userAge>
                <gender>".$_COOKIE["gender"]."</gender>
               </userInfo>";
    else
        print "<stored>false</stored>";
which i handle like so
if(event.result.stored == true)
                    entryPanel.title = "Welcome back " + event.result.userInfo.firstName + " " + event.result.userInfo.lastName;
                    firstName.text = event.result.userInfo.firstName;
                    lastName.text = event.result.userInfo.lastName;
                    userAge.value = event.result.userInfo.userAge;
                    userGender.selectedIndex = event.result.userInfo.gender;
depends on what type of Array you're after
from the sounds of it (with the mention of picture tooltips) you're trying to create a gallery with an image, and a tooltip.
so i'd probably adopt something like
<picture>
     <location>example1.png</location>
     <tooltip>tooltip for picture #1</tooltip>
</picture>
<picture>
     <location>example2.png</location>
     <tooltip>tooltip for picture #2</tooltip>
</picture>
<picture>
     <location>example3.png</location>
     <tooltip>tooltip for picture #3</tooltip>
</picture>
etc...
or
<picture location="example1.png" tooltip="tooltip for picture #1"/>
<picture location="example2.png" tooltip="tooltip for picture #2"/>
<picture location="example3.png" tooltip="tooltip for picture #3"/>
etc...

How to get the value from a database without submitting a jsp page

I have a jsp which has a text box depending on the value entered I want to get the value from a database for other two fields with out submitting jsp page. I am using struts.
Thanks For any assistance provided.

Alright,here is an example for you for the first case.
Present.jsp:
============
<html:html>
<head>
<title><html:message key="page.title"/></title>
</head>
<body>
<html:form action="ChangeEvent.do">
<html:hidden property="method"/>

Emp Id:<html:text property="empId" size="5" onkeyup="if(true){this.form.elements[0].value='populateDetails';this.form.submit();}"/>
Emp Name:<html:text property="empName" size="10" />
Email Address:<html:text property="email" size="10" />
<html:submit>Submit</html:submit>
</html:form>
</body>
</html:html>struts-config.xml:
==================
<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.1//EN" "http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd">
<struts-config>

<form-beans>
<form-bean name="employeeFormBean" type="org.apache.struts.action.DynaActionForm">
   <form-property name="empId" type="java.lang.String"/>
   <form-property name="empName" type="java.lang.String"/>
   <form-property name="email" type="java.lang.String" />
</form-bean>
</form-bean>
<action-mappings>
<action path="/ChangeEvent" type="Test.GetChangeAction" name="employeeFormBean" scope="request" parameter="method">

<forward name="success" path="/Present.jsp"></forward>
<forward name="failed" path="/error.jsp"></forward>
</action>
</action-mappings>
</struts-config>GetChangeAction.java:
=====================
public class GetChangeAction extends DispatchAction{
public ActionForward populateDetails(ActionMapping mapping,ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception {
        DynaActionForm dForm = (DynaActionForm)form;
        String empId = dForm.get("empId");
        // calling Model / Db and then getting back Employee Details
        EmployeeBean eb = ModelUtils.getDetails(empId);
        // Updating form bean by updating values from the Model
        dForm.set("empName".eb.getEmpName());
        dForm.set("email".eb.getEmail());
        return mapping.findForward("success");
}well to me this should work regardless to any browser but we need to make sure we put in our logic properly.

How to port a project from a database to another

Can any help me find a documantation how to port my metadata project from one database to another step by step. I get problem with the location and connector in mapping when import the metadata file (mdl)

I have to do the same task here. Still couldn't start this task though...
But I believe I'll use the MDL file. I don't see how avoid the connector/location issue either. I believe that migrating OWB's repositories demands to recreate this structures...
If anyone else knows how to overcome this issue, I'd be glad to know how!
