How do i implement the RMAN

Dear Oracle experts,
I am new for RMAN. I am good with Backup/recovery concepts. But I do not know about the RMAN concepts. Can you please provide the steps to implement the RMAN and how to recover the data file by using RMAN.
Can you please guide me?
I would really appreciate, if you could give me the steps to implement the RMAN. I am using oracle9i.
Thanks in advance.

There are articles on the Web - a google search will
reveal these. However, the best place to start is,
as always, the documentation. See:
http://download-west.oracle.com/docs/cd/B10501_01/server.920/a96564/toc.htm
Hope this helps.
Kailash.

How can I implement the connection pool in my java stored procedure

my java stored procedures (in database 'B') have to connect to another oracle database ,let's say 'A'. And how can I implement the behavior like the so-called connection pool in my java stored procedure in 'B', as below.
1. database B, has 2 java stored procedures sp1 and sp2
2. both sp1 and sp2 connects to databse 'A'
whatever I call the sp1 and sp2 and the database 'A' always only one connected session from sp1 and sp2 in database 'B'.
THANKS A LOTS...

my problem is I have a lots of java stored procedures need to cnnect to the remote oracle db, and I hope the remote db can only have a connected session from my java stored procedures in my local db. I try as below
class sp{
static Connection conn=null; //the remote db connection,
public static void sp1(){...}//procedure 1, using conn
public static void sp2(){...}//procedure 2, using conn,too
I can 'see' the 'conn' variable if I invoke the sp1() and sp2() from the same client application(maybe sqlplus). But if I invoke the sp1() from client 'A' and invoke sp2() from client 'B' then the sp1() and sp2() can not see the 'conn' variable for each other. I think it's because the two clients cause oracle to create two instances of the class 'sp' and the sp1() and sp2() located in different instance seperately. Thus the sp1() and sp2() can not see 'conn' for each other. They can only see its own 'conn'.
To connect to the remote db from the java stored procedure is easy but is it possible to connect to the remote db via database link from the java stored procedure at my local db ? If so, then I also archive my goal .
BTW , thanks a lots...

How I would implement the print mehtod?

* SinglyLinkedList.java
* An implementation of the List interface using a
* singly linked list.
* (P) 2000 Laurentiu Cristofor
* Modified (slightly) for s03 by D. Wortman
// The class SinglyLinkedList provides an implementation of the List
// interface using a singly linked list. This differs from the Java
// class LinkedList, which employs a doubly linked list and includes
// additional methods beyond those required by the List interface.
// Note: Included in this file is (at least) a "stub" method for each of
// the required methods, as well as an implementation of the Node class.
// This allows the file to compile without error messages and allows
// you to implement the "actual" methods incrementally, testing as you go.
// The List interface include some "optional" methods, some of which are
// included here (see the List API for the meaning of this).
// Some of the methods are preceded by comments indicating that you are
// required to implement the method recursively. Where there are no
// such comments, you can provide either an iterative or a recursive
// implementation, as you prefer.
// There are some methods that you are asked not to implement at all.
// Leave these as they are here: they are implemented here to just
// throw an UnsupportedOperationException when they are called.
// Hint: Read carefully the comments for the interface List in the
// online documentation (Java API). You can also take a look at the
// implementation of the LinkedList class from the API. It uses a
// doubly linked list and it is different in many places from what
// you need to do here. However it may help you figure out how to do
// some things. You shouldn't copy the code from there, rather you
// should try to solve the problem by yourself and look into that code
// only if you get stuck.

can someone help me, please.
Thank You
Ennio

actually, you would do the same thing for a toString() method as you would for a print() method. You are just going to return a String instead of using i/o. I would use an iterator to walk over your list of Nodes and then call toString() on each object in your list of Nodes.

How to do implement the FrameAccess.java code in my project

Iam doing an project in java for inserting the videos into oracle9i and searching the inserted videos using the frames of the videos inserted.I have done the project to insert and search the videos.But i have been asked to put an EXTRACT button to extract all the frames of the video being inserted.Please help me to implement the FrameAccess.java coding in my existing coding.I have pasted my coding(VideoInsert.java) and FrameAccess.java(used to extract frames) coding.
The VideoInsert.java when executed will contain browse button to choose the video file(only .mpg files) to be inserted into the database.After selecting the file and when we press open button in the Open dialog box,the video will be played in jmf player in a separate window and the filepath of the video will be included in the textbox.Now what i need is,an extract button should be placed and when it is clicked,the frames of the corresponding selected video has to be extracted in the location where the project files are stored i.e.,the FrameAccess.java coding has to be executed.
Please help me if anyone knows how to implement the above concept.

WPF How can I implement the INotifyPropertyChanged in a Three-tier architecture?

I am a student and I am confused on using the INotifyPropertyChanged in a three-tier style of coding. Can you guys help me a bit with these?
I have a solution named MetroAppProject. It is composed of four projects (I omitted the using clauses and references, just imagine they are there and are working fine):
1. MetroApp.BluePrints - a class library composed of the classes in my sql db
An example of my class
namespace MetroApp.BluePrints
public partial class Patient
public long Id { get; set; }
public string PatientNumber { get; set; }
public string LastName { get; set; }
public string FirstName { get; set; }
public string MiddleName { get; set; }
public string AddressLine1 { get; set; }
public Nullable<short> CityId { get; set; }
public string CityName { get; set; }
public Nullable<short> ProvinceId { get; set; }
public string ProvinceName { get; set; }
Then the second project:
2. MetroApp.DataAccess = a class library composed of methods that calls my sql procedures. I used the SqlHelper class which contains the connection strings and other stuffs.
example class
namespace MetroApp.DataAccess
public class PatientDb
public Patient Retrieve(PatientParams parameters)
SqlCommand command = new SqlCommand();
Patient singItem = new Patient();
command.CommandText = "RetrievePatients";
command.CommandType = CommandType.StoredProcedure;
command.Parameters.AddWithValue("@Id", parameters.Id).Direction = ParameterDirection.Input;
DataTable dt = SqlHelper.GetData(command);
if (dt.Rows.Count > 0)
DataRow row = dt.Rows[0];
singItem.Id = TDefaultValue.GetInt(row["Id"].ToString());
singItem.PatientNumber = TDefaultValue.GetString(row["PatientNumber"].ToString());
singItem.LastName = TDefaultValue.GetString(row["LastName"].ToString());
singItem.FirstName = TDefaultValue.GetString(row["FirstName"].ToString());
singItem.MiddleName = TDefaultValue.GetString(row["MiddleName"].ToString());
singItem.AddressLine1 = TDefaultValue.GetString(row["AddressLine1"].ToString());
singItem.CityId = TDefaultValue.GetShort(row["CityId"].ToString());
singItem.CityName = TDefaultValue.GetString(row["CityName"].ToString());
singItem.ProvinceId = TDefaultValue.GetShort(row["ProvinceId"].ToString());
singItem.ProvinceName = TDefaultValue.GetString(row["ProvinceName"].ToString());
return singItem;
public List<Patient> RetrieveMany(PatientParams parameters)
var items = new List<Patient>();
var command = new SqlCommand();
command.CommandText = "RetrievePatients";
command.CommandType = CommandType.StoredProcedure;
command.Parameters.AddWithValue("@Id", parameters.Id).Direction = ParameterDirection.Input;
command.Parameters.AddWithValue("@PatientNumber", parameters.PatientNumber).Direction = ParameterDirection.Input;
command.Parameters.AddWithValue("@LastName", parameters.LastName).Direction = ParameterDirection.Input;
command.Parameters.AddWithValue("@FirstName", parameters.FirstName).Direction = ParameterDirection.Input;
command.Parameters.AddWithValue("@MiddleName", parameters.MiddleName).Direction = ParameterDirection.Input;
command.Parameters.AddWithValue("@CityId", parameters.CityId).Direction = ParameterDirection.Input;
command.Parameters.AddWithValue("@ProvinceId", parameters.ProvinceId).Direction = ParameterDirection.Input;
DataTable dt = SqlHelper.GetData(command);
foreach (DataRow row in dt.Rows)
var item = new Patient();
item.Id = TDefaultValue.GetLong(row["Id"].ToString());
item.PatientNumber = (row["PatientNumber"].ToString());
item.LastName = (row["LastName"].ToString());
item.FirstName = (row["FirstName"].ToString());
item.MiddleName = (row["MiddleName"].ToString());
item.AddressLine1 = (row["AddressLine1"].ToString());
item.CityId = (short)row["CityId"].ToString();
item.CityName = (row["CityName"].ToString());
item.ProvinceId = (short)row["ProvinceId"].ToString();
item.ProvinceName = (row["ProvinceName"].ToString());
items.Add(item);
return items;
public bool Insert(Patient entity, int userId, ref bool doesExist)
var command = new SqlCommand();
try
command.CommandText = "AddPatient";
command.CommandType = CommandType.StoredProcedure;
command.Parameters.AddWithValue("@PatientNumber", entity.PatientNumber).Direction = ParameterDirection.Input;
command.Parameters.AddWithValue("@LastName", entity.LastName).Direction = ParameterDirection.Input;
command.Parameters.AddWithValue("@FirstName", entity.FirstName).Direction = ParameterDirection.Input;
command.Parameters.AddWithValue("@MiddleName", entity.MiddleName).Direction = ParameterDirection.Input;
command.Parameters.AddWithValue("@AddressLine1", entity.AddressLine1).Direction = ParameterDirection.Input;
command.Parameters.AddWithValue("@CityId", entity.CityId).Direction = ParameterDirection.Input;
command.Parameters.AddWithValue("@ProvinceId", entity.ProvinceId).Direction = ParameterDirection.Input;
command.Parameters.AddWithValue("@Id", entity.Id).Direction = ParameterDirection.Input;
command.Parameters.Add("@DoesExist", SqlDbType.Bit).Direction = ParameterDirection.Output;
int result = SqlHelper.ExecuteNonQuery(command);
doesExist = (bool)(command.Parameters["@DoesExist"].Value);
entity.Id = (int)(command.Parameters["@Id"].Value);
if (result == 0 || doesExist)
return false;
return true;
catch (Exception)
return false;
public bool Update(Patient entity, int userId, ref bool doesExist)
var command = new SqlCommand();
try
command.CommandText = "EditPatient";
command.CommandType = CommandType.StoredProcedure;
command.Parameters.AddWithValue("@PatientNumber", entity.PatientNumber).Direction = ParameterDirection.Input;
command.Parameters.AddWithValue("@LastName", entity.LastName).Direction = ParameterDirection.Input;
command.Parameters.AddWithValue("@FirstName", entity.FirstName).Direction = ParameterDirection.Input;
command.Parameters.AddWithValue("@MiddleName", entity.MiddleName).Direction = ParameterDirection.Input;
command.Parameters.AddWithValue("@AddressLine1", entity.AddressLine1).Direction = ParameterDirection.Input;
command.Parameters.AddWithValue("@CityId", entity.CityId).Direction = ParameterDirection.Input;
command.Parameters.AddWithValue("@ProvinceId", entity.ProvinceId).Direction = ParameterDirection.Input;
command.Parameters.AddWithValue("@Id", SqlDbType.Int).Direction = ParameterDirection.Output;
command.Parameters.Add("@DoesExist", SqlDbType.Bit).Direction = ParameterDirection.Output;
doesExist = (bool)(command.Parameters["@DoesExist"].Value);
int result = SqlHelper.ExecuteNonQuery(command);
if (result == 0 || doesExist)
return false;
return true;
catch (Exception)
return false;
Then a business logic
3. MetroApp.BusinessLogic = class libray for calling the methods from DataAccess
namespace MetroApp.BusinessLogic
public class PatientMgr
#region Fields
private readonly PatientDb _db;
#endregion
#region Properties
public Patient Entity { get; set; }
public List<Patient> EntityList { get; set; }
public PatientParams Parameters { get; set; }
#endregion
#region Constructors
public PatientMgr()
_db = new PatientDb();
Entity = new Patient();
EntityList = new List<Patient>();
Parameters = new PatientParams();
#endregion
#region Methods
public Patient Retrieve(PatientParams parameters)
return _db.Retrieve(parameters);
public List<Patient> RetrieveMany(PatientParams parameters)
return _db.RetrieveMany(parameters);
public bool Insert(Patient entity, int userId, ref bool doesExist)
return _db.Insert(entity, userId, ref doesExist);
public bool Update(Patient entity, int userId, ref bool doesExist)
return _db.Update(entity, userId, ref doesExist);
#endregion

I apologize for the long post. As you can see, I don't use binding. Binding requires me to use INotifyPropertyChanged interface which I am not familiar. Can you at least make my project to implement the INotifypropertyChanged?
Here is my sample code for the WPF page:

readonly PatientMgr itemMgr = new PatientMgr();
public PatientParams CurrentPar = new PatientParams(); // for undoActionType _action = ActionType.Insert; // this is an enum from another project, ActionType.Insert, ActionType.Update
public ActionType Action
get { return _action; }
set { _action = value; }

Hello Kokombads,
I thought you are using MVVM from your title but it seems your project is just a simple WPF project. In that way, please check the following msdn article to know how to Implement Property Change Notification
https://msdn.microsoft.com/en-us/library/ms743695(v=vs.110).aspx
using System.ComponentModel;
namespace SDKSample
// This class implements INotifyPropertyChanged
// to support one-way and two-way bindings
// (such that the UI element updates when the source
// has been changed dynamically)
public class Person : INotifyPropertyChanged
private string name;
// Declare the event
public event PropertyChangedEventHandler PropertyChanged;
public Person()
public Person(string value)
this.name = value;
public string PersonName
get { return name; }
set
name = value;
// Call OnPropertyChanged whenever the property is updated
OnPropertyChanged("PersonName");
// Create the OnPropertyChanged method to raise the event
protected void OnPropertyChanged(string name)
PropertyChangedEventHandler handler = PropertyChanged;
if (handler != null)
handler(this, new PropertyChangedEventArgs(name));
It is not so complex, you only need to refer to the interface from here:
https://msdn.microsoft.com/en-us/library/system.componentmodel.inotifypropertychanged(v=vs.110).aspx
And understand that you have to do the following:
For change notification to occur in a binding between a bound client and a data source, your bound type should either:
Implement the INotifyPropertyChanged interface (preferred).
Provide a change event for each property of the bound type

How can i implement the default value for this variable?

In one of our Stored procs,we have a variable RECS_TO_DELETE, which determines the number of records to delete from various DELETEs that happen within this proc.
The value for RECS_TO_DELETE variable should be obtained from a configuration table sys_config
select
rec_num into RECS_TO_DELETE
from sys_config
where
sys_code=55;
But if something goes wrong with sys_config table or the above SELECT INTO, our client wants to makes sure that RECS_TO_DELETE should have a default value of 1000.
In the code, how will i implement having this default value of 1000 for RECS_TO_DELETE variable in case the above SELECT INTO fails for some reason.

Hi,
You have to assign a value before the execution...
DECLARE
    RECS_TO_DELETE NUMBER(9) := 1000;
BEGIN
    SELECT rec_num
    INTO   RECS_TO_DELETE
    FROM   sys_config
    WHERE sys_code = 55;
    DBMS_OUTPUT.put_line(RECS_TO_DELETE);
EXCEPTION
    WHEN NO_DATA_FOUND THEN
       DBMS_OUTPUT.put_line(RECS_TO_DELETE);
END;
/Regards,

How i can implement the desired format in ODI ??

Hi
i want to export data from table to file
but in file i have specific format like
Account Number :A123456
Cutomer 1
Customer 2
Customer 3
Account Number : B999999
Cutomer 4
Customer 5
Customer N
How i can implement this
plz suggest me possible solutions for this
thanks

Hi,
I have done this before by using three files. The first file contains the header row - in your case, I would create a variable which selects the account number via rownum for example (you could add another variable so you could increment the rownum until exhausted). Then in the first ODISqlUnload
select 'Account Number :'||#variable.account_number
from table.
This creates you header row in a file
Then, in a second ODISqlUnload, select the 'Customer' data for the account number into another file
select customer_details
from table
where account_number = #variable.account_number.
So you end up with a list :
Customer 1
Customer 2
etc etc
Then using an ODIFileAppend, append the two files created above in the final output file. Then loop round in a package for all your account numbers, using the two temp files, then append to the final output.
Your final output file, then looks like:
Account Number :A123456
Customer 1
Customer 2
Customer 3
Account Number : B999999
Customer 4
Customer 5

How do I implement it? Thanks a lot.

Hi!
You don´t need to apply this change manually. You can do it directly in transaction SNOTE with the Note Assistant. You will need to download the Note from this transaction and then apply it.
Remember you will also need to apply some manual changes, apart from the source code correction.Follow the steps mentioned on the Note:
Call Transaction SE51. Enter the following parameters on the initial screen:
Program: SAPVF040
Screen number: 1002
Subobject: Layout Editor
Press the "Change" button.
Double-click the field BSEG-SGTXT. On the screen "Screen Painter: Attributes", change the defined length field attribute to 50. Save and activate the change.

Antonio

How can I implement the equivilent of a temporary table with "on commit delete rows"?

hi,
I have triggers on several tables. During a transaction, I need to gather information from all of them, and once one of the triggers has all the information, it creates some data. I Can't rely on the order of the triggers.
In Oracle and DB2, I'm using temporary tables with "ON COMMIT DELETE ROWS" to gather the information - They fit perfectly to the situation since I don't want any information to be passed between different transactions.
In SQL Server, there are local temporary tables and global. Local temp tables don't work for me since apparently they get deleted at the end of the trigger. Global tables keep the data between transactions.
I could use global tables and add some field that identifies the transaction, and in each access to these tables join by this field, but didn't find how to get some unique identifier for the transaction. @@SPID is the session, and sys.dm_tran_current_transaction
is not accessible by the user I'm supposed to work with.
Also with global tables, I can't just wipe data when "operation is done" since at the triggers level I cannot identify when the operation was done, transaction was committed and no other triggers are expected to fire.
Any idea which construct I could use to acheive the above - passing information between different triggers in the same transaction, while keeping the data visible to the current transaction?
(I saw similar questions but didn't see an adequate answer, sorry if posting something that was already asked).
Thanks!

This is the scenario: If changes (CRUD) happen to both TableA and TableB, then log some info to TableC. Logic looks something like this:
Create Trigger TableA_C After Insert on TableA {
If info in temp tables available from TableB
        Write info to TableC
   else
       Write to temp tables info from TableA
Create Trigger TableB_C After Insert on TableB {
If info in temp tables available from TableA
        Write info to TableC
   else
       Write to temp tables info from TableB
So each trigger needs info from the other table, and once everything is available, info to TableC is written. Info is only from the current transaction.
Order of the triggers is not defined. Also there's no gurantee that both triggers would fire - changes can happen only to TableA / B and in that case I don't want to write anything to TableC.
The part that gets and sets info to temp table is implemented as temp tables with "on commit delete rows" in DB2 / Oracle.
What do you think? As I've mentioned, I could use global temp tables with a field that would identify the transaction, but didn't find something like that in SQL Server. And, the lifespan of local temp tables is too short.

How can i implement the event-dependent sequential operation of devices?

I am trying to develop a code to automate the valve operations of a gas plumbing system. for example, i would like to select "leak test" from an enumerated list and then have the system open some valves (digital output), wait for user confirmation, open more valves, activate compressor, wait for certain pressure (analog input), close certain valves, continue compressing untill certain pressure, stop compressing, wait 60 minutes while logging pressure readings. That is basically what i'm trying to implement. i am stuck on how to carry this out. i already have somewhat of a state machine built, my trouble is with the structure of how to build the sequence. I know this is probably vague, i'll answer any questions anyone has. Thank you very much.
Brian

Take a look at a Queued State Machine. Here you build a list of the order of steps to take. It could either an array where at the end of each step, it picks off the next item on the array. Or it could actually be a queue. The next state to operate gets picked off the queue. You would preload the queue with all of your desired steps. On each iteration, it would dequeue the next state to do. In the cases where you need to repeat a step (such as continually doing a step until a condition as been met) you would re-enqueue the same step at the front of the queue.

How can i implement the communication between processes?

the processes must run in the machine which has small
