Convert 32/64-bit word size: 

Converting a database from 32/64-bit word size to 64/32-bit word size can be done using this feature of DbClone. The existing database word size can be changed to make it suitable for the hosts, which have 32 or 64 bit operating systems.

In order to use this feature, the source host should be having two oracle homes of same version installed with different word sizes i.e. one with 32 bit word size and the other with 64 bit word size. Then only the conversion can take place across these. The conversion of the 32/64 bit word size can be done only the single host and not across different hosts.

 In the conversion process, the existing database is completely changed to the new database and the old copy of the database is lost and it will be removed from the source host node of the DbClone tree and is added to the target host node. If you would like to keep the old copy of Database then you need to clone it first and then convert the word size of the cloned database.

The inputs required to use this features are:
