Hardware doubts when i clone a database

dear all
i want clone my database in manual way (Note:458450.1) but my question is:
Can i clone a DB if my hardware server destiny have less performance than the production server ???
Here are my facts:
source:
- HP 64 BITS
- 4 GB RAM
- RHEL AS VERSION 5 - 64 bits
- oracle 10g r2
destiny:
- hp 32 bits
- 1GB RAM
- rhel as version 4 - 32 BITS.
- ORACLE 10G R2
If this is possible i must to change what parameters aboot MEMORY in SPFILE.ORA?
Thanks and apologize my english,
cesar.

Yes. You can do that.
Just follow the steps given in Note:458450.1 to clone the DB to new box.
also check the metalink Note:62290.1 -- Changing between 32-bit and 64-bit Word Sizes as the source and destination boxes wordsize is different.
"The on-disk format for database data, redo, and undo is identical for the 32-bit and 64-bit installations of Oracle”
The only internal structural differences between the 32-bit and 64-bit oracle installations are the following:
· The compiled format of PL/SQL is different.
· The storage format of user-defined types (object types, REFs, varrays, and nested tables) is based on the release of Oracle that created the database.
· The existing storage format will be converted to the correct format transparently when necessary.
so...
1. copy all the control , redo , datafiles , init.ora files to destination box
2. Start the DB in upgrade mode
SQL>Startup Upgrade
3. Run @$ORACLE_HOME/rdbms/admin/utlirp.sql to recompile all the pl/sql objects
4. Check the validity of the packages and recompile If invalid.
example: select owner, object_name, object_type from dba_objects Where status <> 'VALID'
5. restart the DB.
Hope this helps. Let me know if any questions.

How to Clone the DataBase

Hi
How to Clone a Dabase .. ??
When the Database is Online (Up and Running).
I want to Clone the Database on the Same System.
Its a testing scenario.
In one of the interview I had faced this quesiton.
Kindly, any one guide me in this regard,
Thanks,
Pavan Kumar

This is a documentation forum.
You need to read that documentation.
Specifically, go to http://docs.oracle.com, select the version of the database you are working with, and put 'clone' into the search box. One link for 10gR2 is http://download.oracle.com/docs/cd/B19306_01/server.102/b14220/startup.htm#sthref1874
IN the future, please have the courtesy to
1) post in an appropriate forum, as described by the title of the forum
2) Include product (database) version and operating system
when asking for assistance

During daily refresh/clone alter database rename file genrating logs under $ORACLE_HOME/dbs with name c-1437102747-20130920-16

Did anyone have seen this behavior?
DB version : 11.1.0.7
OS : HP-UX Itanum
EBS -11.5.10.2
We are doing daily refresh/clone of a database instance from production. Recently we are seeing the growth of $ORACLE_HOME/dbs directory during this
refresh.   During investigation we find out that
1) When we rename the database files after database restoration. Each below command genrating the 24MB of log file under $ORACLE_HOME/dbs.
Command :
alter database rename file '/db02/prod/XDB.dbf' to '/db02/test/XDB.dbf';
alter database rename file '/db02/prod/a_archive01.dbf' to '/db02/test/a_archive01.dbf';
Logfiles under $ORACLE_HOME/dbs on target :
-rw-r----- xxxxx 24379392 Sep 20 05:30 ./dbs/c-1437102747-20130920-02
-rw-r----- xxxxx 24379392 Sep 20 05:30 ./dbs/c-1437102747-20130920-03
2) After few minutes, these logs got removed from the directory.
3) Did not find anything unusual in the alert log.

These are controlfile autobackups.   Every time you make a physical change to the database structure, an autobackup is created. In 11.2, the frequency is reduced -- for example if you make 5 changes in quick succession, one autobackup is created.
CONTROLFILE AUTOBACKUP ON    would be visible when you do a SHOW ALL in rman.

Error when installing Oracle 9i Database.

Dear all experts!
Today, when Oracle was creating database in the first time, errors occur. It's error:
******ora-01041: internal error. hostdef extension doesn't exist.******
Can you show me the way to correct this problem. I need urgent.
Please send email to me via: [email protected]
Thanks and best regards,
Binh Truong

You have not started the windows service or it does not exist. How are you creating the database: using DBCA or manually? DBCA will create windows service automatically. I suggest that you start DBCA, go through all the steps answering all questions but in the end, when it asks for confirmation for creating the database say no and choose option to generate batch files instead. Then study these files to see the correct procedure of creating database and then try that manually.
Best of luck.

How to create a clone of database from STANDBY?

How can i clone a database from physical standby database?

Steps to clone from standby:
1. cancle the managed recovery process on standby
sql>alter database recover managed standby database cancel;
2. Remember your standby databse would be in mount mode.
3. Connect to the auxiliary instance and to the standby database through RMAN
rman target sys/<pwd>@standby auxiliary sys/<pwd>@auxiliary-connection
4. If 11g, then run directly duplicate from active database
rman>duplicate target database to 'auxiliary_db_name' from active database nofilenamecheck;
5. Once, the duplication is done, start the MRP on the standby again
sql>alter database recover managed standby database disconnect from session;
Ok..You are on 10g.
Perform the above steps, but only thing is 1st you need to take the backup of the standby database first.

Problem with data format when getting from a database

I'm trying to get a date from the database but the problem is that it also return the time. I have tried to change the format of the date when retrived from my database but it still returns the time.
Any solutions?
String theDBDate = rset.getString("date_of_call");
SimpleDateFormat formatterdate = new SimpleDateFormat ("EEE, MMM d, ''yy");
String date = formatterdate.format(theDBDate);
theCalls.setDateofCall(date);// callin my Call Class to store the date which is a string

Hi could any help me? I have this problem for the last few day. I gave up on it for a while but today I'm trying to get to the botton of this problem.
I connecting to an oracle database but it return back the date & time but I want only the date.
Here my code.
Locale currentLocale= new Locale("en","GB");
Date today = new Date();
DateFormat formatter = DateFormat.getDateInstance(DateFormat.DATE_FIELD,currentLocale);
String theSQL = (" Select * From Call ") ;
Statement stmt;
stmt = conn.createStatement();
ArrayList CallsList = new ArrayList();
ResultSet rset;
rset = stmt.executeQuery(theSQL);
while(rset.next() == true)
Call theCalls = new Call();
theCalls.setCallNo(rset.getInt("call_no"));
theCalls.setUsername(rset.getString("username"));
theCalls.setCompID(rset.getString("comp_id"));
theCalls.setTimeofCall(rset.getString("time_of_call"));
Date todaydate = rset.getDate("date_of_call");
Timestamp theDBDate = rset.getTimestamp("date_of_call");
SimpleDateFormat formatterdate = new SimpleDateFormat ("EEE, MMM d, ''yy");
String date = formatterdate.format(theDBDate);

"no ocijdbc11 in java.library.path" error when connecting a TNS database co

Hi
"no ocijdbc11 in java.library.path" error when connecting a TNS database connection
I have the same problem 'error code' when testing the connection to a database although I have an APEX db that connects without a problem.
I have re downloaded jre & SQL Developer just to ensure all files are where they should be with no luck.
I've also tried most of the suggestions in various threads.
Does anyone know what exactly causes this error?
eg; should I be looking for a file called 'ocijdbc11' & put it into the 'java.library.path' path?
Can anyone explain to a newbie at db connections what I should do?
I'm using the 'thin' client as the checkbox is clear & I don't know what path to enter into the correct file to make this work??
This is & needs to connect as a TNS connection & was working fine until recently, the only change I can think of is a move of files from the 'C' drive but I thought redownloading SQL Developer would slove this.
Thanks

When you reinstalled SQL Developer, did you install into a new directory (ie rename or delete the old directory first)?
I don't know if system setup contains directory references (which might be invalid after moving the location of SQL Developer). Does renaming your system2.1.1.64.45 directory (in C:\Documents and Settings\username\Application Data\SQL Developer) help? Note that your connections are in the connections.xml file in the o.jdeveloper.db.connection.11.1.1.2.36.55.30 subdirectory of system2.1.1.64.45 - you will either need to export connections before renaming and then import again after or copy this file to test if you can connect.
Finally, the TNS Names directory preference is just a way of telling SQL Developer where to look for the tnsnames.ora file, rather than just assuming it will pick the right one. If you go to create a new connection, do you get the right list of TNS aliases? If not, then set this preference to the directory where the right tnsnames.ora file lives.

Error when I clone a test plan

Hi All
I get the below error when I clone a test plan.
I've no steps or attachments in the test case mentioned below. It helps to more than one test case
clone operation encountered an error while processing test case 21428. Exclude this test case from the suites being cloned and retry the operation. Error details : Failed to parse xml in the UITest file attachment or TCM.Steps field. Make usre this data
is valid and retry the opeartion
Please let me know how to fix this issue?
Thanks

Hi Sathish,
Base on the error message, it seems that there are something issue in test case 21428. I suggest that you could create a new test case that similar to test case 21428 and try again.

Not enough to go on, but that is what oracle is saying.

What happens at backend when we fire alter database commit to switchover to physical standby

Hi,
What exactly happens at backend when we fire alter database commit to switchover to physical standby.
how the transition happens?
Thanks

Hi,
The following will happen at the backend
1.) Notifies the primary database that a switchover is about to occur
2.) Disconnect all users from the primary database
3.) Generate a special redo record that signals the End of Redo (EOR)
4.) Converts the primary database into a standby database
5.) Once the standby database applies the final EOR record, guaranteeing that no data loss has been lost, converts the standby database into the primary database.
The new standby database (old primary) starts to receive the redo records and continues process until we switch back again. It is important to remember that both databases receive the EOR record so both databases know the next redo that will be received.

Pradeep. V
