DB Migration from oracle 8.1 32bit to 64 bit

Question

Hi,
We are working on oracle 8.1 on 32 bit on solaris 64bit operating system. We are working on SAP R/3 4.6C.
We want to migrate our oracle database form 32 bit to 64 bit.
If anyone can help me with some documentation, it would be helpful. Please send to my mail id [email protected]
Also, please suggest some preperatory steps for the same.
Thanks,

Dear ,
you are going to upgrade from 8.1.7.3 (32-bit) to 8.1.7.3 (64-bit).  This
applies if you are running Java inside the database.
1)  Shutdown your 32-bit 8.1.7.3 database.  Shutdown the listener.
2)  Take a cold backup of this database.
3)  Install Oracle RDBMS 8.1.7.0 (64-bit)
4)  Apply patchset 8.1.7.3 (64-bit) to this oracle home.
5)  Copy your init.ora from the 32-bit home to the 64-bit home.
6)  Edit the init.ora of the 64-bit ORACLE_HOME so that the following
    parameters are set as follows:
    aq_tm_processes = 0
    job_queue_processes = 0
    systemtrig_enabled = FALSE
    db_block_buffers= (at least 2000)
    shared_pool_size= (at least 150MB)
    java_pool_size= (at least 20MB)
7)  sqlplus internal or sys
    startup restrict your 8.1.7.3 database using the ORACLE HOME of
    8.1.7.3(64-bit).
8)  delete from duc$ where pack='JIS$INTERCEPTOR$' and proc='USER_DROPPED';
    commit;
    @?/rdbms/admin/utlip.sql
9)  Go to Metalink, select Patches, and put in 1994933 for the 'Patch Number'.
    It will come up with a patch saying that it is for HP, but it is actually
    generic for Oracle on all platforms.
    After downloading the patch, extract it and keep track of where you put
    the rmsro.sql and invalidate.sql files.
10) Now run the following, again from sql*plus connected as internal or sys:
    SQL> @?/javavm/install/initjvmaux.sql
    SQL> @<directory where you placed the files from step 9>/rmsro.sql
    SQL> call rmsro.run();
    SQL> @<directory where you placed the files from step 9>/invalidate.sql
11) shutdown normal the database
12) If you are following this procedure because you are converting word size
    from 8.1.7.3 32-bit to 8.1.7.3 64-bit *ON SOLARIS*, then you also need
    to apply another fix.
    Go to Metalink, select Patches, and put in 2209569 for the 'Patch Number'.
    After downloading the patch, extract it and put the classes.bin file from
    the downloaded patch into $ORACLE_HOME/javavm/admin.  This will replace the
    classes.bin file which is already there.
13) Startup restrict your 64-bit 8.1.7.3 database
14) Sql*plus internal or sys and type
    SQL> create or replace java system
      2  /
15) Shutdown the database
16) Startup restrict the database, connect as internal or sys and run
    SQL> @?/rdbms/admin/utlrp.sql;
    -- To check on the progress of utlrp.sql, you can open a second sql
       prompt and do a select count(*) from dba_objects where status!='VALID';
       This count should keep decreasing as the script progresses to
       revalidate all the objects.
    -- If you get an ORA-29554 unhandled Java out of memory condition error,
       simply rerun utlrp.sql again and it will pick up where it left off.
17) Shutdown the database
    (Note: you may get an ORA-600 [729] error, which can be ignored.
    If that is the case, simply do a shutdown abort before continuing)
18) Change the SYSTEMTRIG_ENABLED parameter in your init.ora as follows.
    SYSTEMTRIG_ENABLED =TRUE
19) Startup restrict, connect as internal or sys and run:
    SQL> insert into duc$ (owner, pack, proc, field1, operation#, seq)
         values ('SYS','JIS$INTERCEPTOR$','USER_DROPPED',0,1,1);
    SQL> commit;
20) shutdown the database
21) Modify the database startup parameters JOB_QUEUE_PROCESSES and
    AQ_TM_PROCESSES (and shared_pool_size/java_pool_size/db_block_buffers if
    you modified them earlier) back to their original values.
22) restart the database
23) check that you are able to startup & shutdown normally the database
    without hanging anywhere.
