Migrate from 32 bit to 64 bit using RMAN

Tested: Oracle 9i R2

OS: Windows 2003 server

This article describes the very simple procedure to migrate a database from Windows 32 bit system to 64 bit using RMAN. Follow the steps below when the need arises to build a new Oracle Applications database instance (for a test migration or when re-organizing an existing production instance, for example). Before starting, plan carefully for such issues as the location of new DATAFILES and space considerations. The steps below specifically address the need to refresh a User-Test / Development instance with current production data.
Migrating through RMAN is much faster than Import/export but using the export/import utilities to rebuild your instance instead of cloning because an export/import rebuild provides the opportunity for clean-up and correction.

Step 1: Take a Backup on Source 32 Bit Server:

Connect the rman target to create a full backup of the database including all archivelogs:

CMD>RMAN TARGET SYS/*****@orcl3 CATALOG catalog/catalog@shaan

run {

Tablespace Management using Toad

You can view all of your tablespace information using toad tablespace screen from Database –> Administer –> Tablespaces Here each table describes different detailed information across all the tablespaces in database. If you open this screen from the toad DBA module then you are also able to see the “space history” and “IO history” tab along with Files, Free space, object, Fragmentation. With these tab you are able to able perform space monitoring and planning steps. These tab permits you check graphically space and IO usage over time. Through this way DBA are also able to estimate ‘Object size’ based on this estimation. From the below “alter tablespace” tab you can § Modify the tablespace and datafile size. § Add new datafile to the tablespace.

Changing National Character Set AL16UTF16 to UTF8

Changing National Character Set AL16UTF16 to UTF8 The national character set is used for data that is stored in table columns of the types NCHAR, NVARCHAR2, and NCLOB. In contrast, the database character set is used for data stored in table columns of the types CHAR, VARCHAR2 and CLOB. Like the database character set, the national character set is defined when the database is initially created and can usually no longer be changed, at least not easily or without involving quite a lot of work (export, recreate database, import). Except when creating the database, where the national character set is defined explicitly, it can change implicitly even when upgrading the database from Oracle8i to Oracle9i (or Oracle10g). You require SYSDBA authorization to change the national character set. Changing the national character set means changing an Oracle Dictionary entry, but no data is changed. $sqlplus /nolog SQL> CONNECT / AS SYSDBA SQL> Select property_...
