Java code to take database backup

Hi,
I need java code which can take Ms.access database backup on 15th of every month. Please help me to do that.
Advance thanks

make a batch file to copy the little db from it's location to the backup location or invoke the backup command with the correct commandline parameters so you do not get prompted for input, go into the Windoz scheduler and tell it to run the batchfile on the 15th of ever month. Doing this with a language is going to be a problem in logistics you do not have to deal with.

Clob/blob in java-code stored in database

Hi!
I want to write some java-code (CREATE OR REPLACE AND RESOLVE JAVA SOURCE NAMED...)
where I want to return an image as blob.
For doing that I have to initialize the blob in the java-code -correct?
I see many examples like
oracle.sql.BLOB.createTemporary(conn, false,oracle.sql.BLOB.DURATION_CALL)
In PL/SQL there is some similar:
dbms_lob.createtemporary(lob_loc => xmlclob, cache => TRUE, dur => dbms_lob.SESSION);
If I have to initialize the blob in the java source, how to do that (using empty_blob, but why using oracle...createTemporary then?)?
I don't want an connection to an remote database, the java-code will be in the database, so can I call createTemporary without >conn<?
(Oracle 10gR2, Windows, Linux, AIX)
The picture will be generated calling other java-code loaded with loadjava.
The java-source I want to write will be wrapped with PL/SQL.
Greetings
Bjørn

Hi!
It seems you can do this:
          try {
               conn = new OracleDriver().defaultConnection();                graphblob = oracle.sql.BLOB.createTemporary(conn, false,oracle.sql.BLOB.DURATION_CALL); // must init
               System.out.println("Blob is init");
          } catch ( java.sql.SQLException sEx ) {
               throw new RuntimeException ("No connection", sEx);

Export java code out of database? difference between Prod and Test

Hi all,
I'm a seasoned DBA, but I have never really dealt with Java, so this is all new to me. Within one of my test databases (10.2.0.3.0), I have a database package - within the package is a procedure that has this Java call:
language java name 'com.clinapps.pmd.etl.interfaces.forecasting.itemtrial.helper.SSFItemOutboundPMDHelper.processSSFItemInterface()';
This Java code goes and exports a file to .xml format. The basic problem is that in our Test environment, there is a problem in the xml file that gets generated - the second line is missing the first few characters. However, in all of our other environments, including Production and Validation, it all works fine - the xml file is good. What has me confused, is that we've done several database refreshes, where we export from production, then import it down to test. So from everything I'm looking at, the schema is exactly the same - but something is different, causing the issue in the xml file that is being generated. I was wondering if I could get into the database and export the Java code, then that is something where I could confirm if there's a difference or not, from Prod to Test.
Does anyone have any input/feedback on how to do this? I've been googling, and tried several methods, including dbms_metadata.get_ddl, and DBMS_JAVA.EXPORT_SOURCE, but I can't get anything to work.
Or if anyone has any other thoughts on how to debug/troubleshoot this, I'd appreciate any ideas!!
Thank you from a Java newbie!!

OK, that is helping me get somewhere!! If I change the query to this, I am getting results:
select obj_num,long_name from SYS."KU$_JAVA_CLASS_VIEW" where LONG_NAME like '%SSFItemOutboundPMDHelper%';
171879
com/clinapps/pmd/etl/interfaces/forecasting/itemtrial/helper/SSFItemOutboundPMDHelper
Note that it has the / instead of the . as the differentiator
Now if I do the second query, I see this:
SQL> select * from SYS."KU$_JAVA_OBJNUM_VIEW" where OBJ_NUM=171879;
OBJ_NUM DATAOBJ_NUM OWNER_NUM OWNER_NAME
NAME NAMESPACE SUBNAME
TYPE_NUM TYPE_NAME CTIME MTIME

Take database backup programmatically

Hi,
I am writing a simplified excel uploader tool for my client. I want to programmatically take the backup of company database whenever my tool is used to upload data into SAP database.
Which method of which object should I use?
Thanks.

Hello,
If you are working on Linux,
Step-1: Set environment from Oracle user:
$ . oraenv (and then specify SID: orcl)
Step-2: Start RMAN:
$ rman target /
or
$ RMAN
RMAN> connect target database sys/oracle_4U
Step-3: Take backup of your database:
RMAN> backup database;
OR,
RMAN> BACKUP DATABASE PLUS ARCHIVELOG;
Thanks,

Need to take Reprository backup in SAP BI7.0

Hi,
      Now I am using SAP BI7.0 server and I am planning to take backup.
I am planning to take the backup only the Metadata Repository. I need only the Structure to take backup because I am not having space to take Database backup so I am planning to take Repository backup only.
Any Once can suggest how to take Metadata Repository from RSA1 t-code.
Any One can give the replay ASAP.

Check the Key Fields in the DSO.
Ex: Key Fields are EMPID, JOB and Data Fields are Startdate and end date...
When you are trying to load the following data
1221   HR 01.01.2009        12.12.2009
1221   HR 01.01.2010         12.12.2010
Once you hve loaded the above data you will get only one record in DSO.
ONce you include the Startdate and enddate fields in KEYFIELDS of DSO you will get two records.
May be you are also facing the similar issue. Have a check with Key fields of DSO.

Code include from database through servlet into jsp

Hi all,
Im alittle stuck at the moment. I need to store code in a database that will be retrieved and displayed on a webpage. I know how to retrieve the information and display it if it is just normal data. The data in the database will be html along with java code that has to be included into the jsp page. Im doing the retrieve in a java bean and the servlet uses that bean to pass the information to the jsp.
How can i include to code into the jsp so that it doesnt show as text but is included into the jsp?? Is this possible??
Niall

Hi,
If you are storing Java code in your database (a Java class file), perhaps you could use class loader and 1) retrieve your code as regular file, 2) use class loader to load it, 3) run methods from your newly created class.
Maybe you can write some sample code that loads any class from a file and calls methods on it, then you could modify that code and fit it in your servlet/JSP code.

Java code and jsp interaction

Hi,
How does one interact between java code and jsp page.That is, if the java code does say database connection, the web page should tell that the connection has been made,just like an application but this will work on the web server not in the console.Kindly let me know.
As

Just curious but where do these questions come from? A course you are taking or you are building something for a hobby?
If you are building some small simple web-app it's probably quicker to embed code right onto your JSP page.
There are various levels of abstracting your web-app separating display from logic from the model.
The following are techniques from simple web-apps to more complicated ones.
-Embedding script right into your JSP
-Using beans
-Using custom tags ( I think there are some standard ones now, struts seems to be a popular buzzword)
-Including a servlet to handle your requests redirect, update bean content grab info form your database and forward to a JSP. (Read up on model 2 architecture.)
To include as much detail as possible would be to write a book. Fortunately many have so I don't have to fit one in this tiny reply box.
Hope that was somewhat useful.

SQL Server Database backup

Hi Team ,
I have SQL Cluster 2012 server running with Couple of Critical data base instance . Each instance installed in different drive.
One of my application database is having mdf of size 1 Gb and ldf is 250 GB . Database is set to full recovery model.
Now I want to change recovery model to simple and want to shrink the los also. before than I want to take database backup.
I have 50 GB space left in drive .
i want to take full database backup on same drive .please let me know how much space i need on that drive to take full backup.
thanks
Ravi

There are two options for you here
1. Take transaction log backup and try shrinking the log file but you might have to take multiple transaction log backups to actually shrink the log file
2. If you are switching from full recovery to simple you dont need to take full backup reason is switching from full to simple breaks log chain so its better to have Transaction log backup and like Praveen suggested if you take transaction log backup with
compression it likely it would fit in free space. But you have to try.
3. This you have to do on your own risk: (If backup of log in point 2 fails) I dont think changing from full recovery to simple would cause any
data loss. So you can switch to simple shrink logs switch back to full and schedule frequent log backups
Reason why log grew so much because you did not took sufficient transaction log backups. So create maintenance plan which would take frequent log backups also if you dont want point in time recovery for this database let it be in simple recovery

DBACockpit Configuration - Remote Database backup of Java Stack.

Hi All,
I am configuring remote database backup of my SAP Java stack system.
I have successfully connected the system in dbacockpit. I have gateway installed also on the remote host system. but Database scheduling on DB13 failed.
On the OS of CEN system, I can connect to the host system of the remote using the OPS$ logon and i.e
sqlplus /@SID as sysdba - (It connected, to confirm i querried the v$instance I was also able to shutdown the remote system)
E:\>sqlplus /@SID as sysdba
SQL*Plus: Release 10.2.0.4.0 - Production on Wed May 18 15:37:46 2011
Copyright (c) 1982, 2007, Oracle. All Rights Reserved.
Connected to:
Oracle Database 10g Enterprise Edition Release 10.2.0.2.0 - 64bit Production
With the Partitioning, OLAP and Data Mining options
But when I ran the brtools to perform the backup I got this error.
"BR0301W SQL error -12560 at location BrDbConnect-2, SQL statement:

Hi Niyi,
This is a TNS error. The system is not able to connect TNS by using br*tools.
Firstly, check your environment variables. They should be as same as java system environmnt variables.
Secondly, check the link below;
[BR0301W SQL error -1017;
You need to create a synonym and SAPUSER table for the gateway installation <sid>adm user on Java database. By doing so, br*tools will be able to connect to the java database.
Best regards,

I tried to put my 'user' and 'pw' credentials I used when connecting with SQL*PLUS:
value1=my_user_name
value2=my_pw
value3=my_schema
but it doest work. Besides where could have I to put the 'WORKSPACE" name?
Thanks for any help.

Yes, the network connection could not be established. Like the error said.
What you're asking about is the exact reason, but that could be any number of things and not at all related to code. You could have the wrong host, the wrong port. A firewall could be blocking the outgoing connection, a firewall could be blocking the incoming connection. Etc. etc.

Populate Flex Tree from Java Code (Database)

Hi
Can someone please help me? I'm very new to using flex. I'm
basically trying to create a tree that is populated from data in my
database. I am using hibernate to fetch that data.
The plan is to basically create the tree in Java code (since
I don't want any processing done on the client PC) and then pass
this to the flex tree (or an actionscript data structure that is
compatible as the tree datasource)
I am creating the java tree using DocumentImpl. Is this
correct? What class would work?
Element e = null;
Node n = null;
Document xmldoc= new DocumentImpl();
Element root = xmldoc.createElement("USERS");

This is hardly a useful comment and must discourage new users
from asking questions. If you think the documentation relating to
the use of the tree control is straightforward then I beg to
differ.
If you are aware of a clear example of how to use the data
tree with a php backend returning a remote data object please
enlighten me. Meanwhile I continue my search but not within the
livedocs.

Can I take a backup of a database in standby mode?

Can I run backup on a database that is in standby mode because it is the DR box receiving log shipping?
Does that work in SQL 2005? How about SQL 2000?
Thanks.
Josh
ps - I know I should just try it, I've already Googled it - with mixed results.

https://connect.microsoft.com/SQLServer/feedback/ViewFeedback.aspx?FeedbackID=466121
Please allow backup of database in standby mode!
This comes up as a very common requirement in HA/DR planning. Logs are shipped over a (relatively) small pipe to a DR site, for days or weeks or months. As part of a (partial) failover plan, we need a full backup of a current version of the database to restore on another server on the DR side - but we cannot take the main DR (secondary) copy out of standby without breaking the log chain. Yes, we might have to pause the application of logs - or possibly not - in order to take the backup of a large-ish database. But the alternative is shipping a large backup all the way from production over that small pipe, which can be prohibitive.
Thanks for the reminder, Tibor.

How to create a oracle database by java code?

how to create a oracle database by java code?
please give some ways then that way's code

I'm not sure what you mean with "database". Do you mean an Oracle instance or an Oracle user/schema (probably the latter, because that's the equivalent to a MS SQL Database).
Creating an instance is definitely not possible from within Java. To create a new user this should be possible, as this can be done with SQL:
GRANT connect,resource TO <newuser> IDENTIFIED BY <password>;
I'm always cautious with questions like this. In 90% of the cases there is something wrong with the initial design. Creating a database shouldn't be something the application is doing.

Connecting to the Oracle 10g Database through Java code

I have a Oracle 10g database to be connected to.
Through sql plus, I can connect to it using the following command
sqlplus "sys@pmi as sysdba"and password is 'password'
how do I connect to this db through my Java code?
I tried
_connection = DriverManager.getConnection("jdbc:oracle:thin:@10.245.4.100:1521:pmi as sysdba", "sys", "password");but it gave the exception "ExceptionIo exception: Connection refused(DESCRIPTION=(TMP=)(VSNNUM=169869568)(ERR=12505)(ERROR_STACK=(ERROR=(CODE=12505)(EMFI=4))))"
I also tried
_connection = DriverManager.getConnection("jdbc:oracle:thin:@10.245.4.100:1521:pmi", "sys", "password");but this gives the exception "ExceptionORA-28009: connection as SYS should be as SYSDBA or SYSOPER"
Can anyone please help me in writing the line of code

You need to use the getConnection syntax that requires a Properties object.
