ASM TO FILE system – Technology Geek

1. Create spfile in ASM “+DATA” disk group :

SQL> connect / as sysdba


SQL> show parameter spfile
 
NAME TYPE VALUE
------- ------- ------------------------------
spfile string /u01/app/oracle/product/11.2.0/db_1/dbs/spfileracdb11.ora
 
SQL> create pfile='/u01/app/oracle/product/11.2.0/db_1/dbs/initracdb11.ora' from spfile='/u01/app/oracle/product/11.2.0/db_1/dbs/spfileracdb11.ora';

SQL> create pfile from spfile
File created.
 
SQL> create spfile='+DATA' from pfile='/u01/app/oracle/product/11.2.0/db_1/dbs/initracdb11.ora';
File created.

SQL> exit

2. Modify initracdb11.ora on rac1 and initracdb12.ora on rac2 files to point to location in ASM

[oracle@rac1 dbs]$ echo "SPFILE='+RACDB_DATA/racdb1/spfileracdb1.ora'" > /u01/app/oracle/product/11.2.0/db_1/dbs/initracdb11.ora
[oracle@rac1 dbs]$ ssh rac2 "echo \"SPFILE='+RACDB_DATA/racdb1/spfileracdb1.ora'\" > /u01/app/oracle/product/11.2.0/db_1/dbs/initracdb12.ora"

3. Update OCR with new SPFILE location

[oracle@rac1 dbs]$ srvctl modify database -d racdb1 -p +RACDB_DATA/racdb1/spfileracdb1.ora

4. Rename any existing spfiles in $ORACLE_HOME/dbs

5. Restart all instances to switch to new SPFILE

6. Check New Location For Spfile .

There’s More than One Way For this Migration you can use what you want

Lets Get The Database Data Files :

1-See your Database Files :

SQL>select file_name from dba_data_files;

+DATA/test/datafile/undotbs1.301.697649965
+DATA/test/datafile/sysaux.300.697649963
+DATA/test/datafile/system.299.697649963
+DATA/test/datafile/users.302.697649965
+DATA/test/datafile/users.309.697650601

select tablespace_name,count(file_name) from dba_data_files group by tablespace_name ORDER BY 2

Use the above query to see how many data files under tablespace .

Now After see the DataFile , we need to create new Directory to copy the data file to it .
mkdir /app/oracle/TEST

2- We Will Create Our Own Script And Copy our Database File to our new location :

sqlplus / as sysdba

set lines 120 pages 0

select ‘copy datafile ‘||file_id||’ to ‘||”’/app/oracle/TEST/’||substr(file_name,21,instr(file_name,’.’)-21)||’_01.dbf”’||’;’ from dba_data_files order by 1;

copy datafile 1 to ‘/app/oracle/TEST/system_01.dbf’;

copy datafile 2 to ‘/app/oracle/TEST/sysaux_01.dbf’;

copy datafile 3 to ‘/app/oracle/TEST/undotbs1_01.dbf’;

copy datafile 4 to ‘/app/oracle/TEST/users_01.dbf’;

copy datafile 5 to ‘/app/oracle/TEST/users_02.dbf’;

shutdown immediate;

startup mount;

exit

rman target /

copy datafile 1 to ‘/app/oracle/TEST/system_01.dbf’;

copy datafile 2 to ‘/app/oracle/TEST/sysaux_01.dbf’;

copy datafile 3 to ‘/app/oracle/TEST/undotbs1_01.dbf’;

copy datafile 4 to ‘/app/oracle/TEST/users_01.dbf’;

copy datafile 5 to ‘/app/oracle/TEST/users_02.dbf’;

exit

sql / as sysdba

select ‘alter database rename file ”’||file_name||”’ to ‘||”’/app/oracle/TEST/’||substr(file_name,21,instr(file_name,’.’)-21)||’_01.dbf”’||’;’ from dba_data_files order by 1;

alter database rename file ‘+DATA/test/datafile/sysaux.300.697649963’ to ‘/app/oracle/TEST/sysaux_01.dbf’;

alter database rename file ‘+DATA/test/datafile/system.299.697649963’ to ‘/app/oracle/TEST/system_01.dbf’;

alter database rename file ‘+DATA/test/datafile/undotbs1.301.697649965’ to ‘/app/oracle/TEST/undotbs1_01.dbf’;

alter database rename file ‘+DATA/test/datafile/users.302.697649965’ to ‘/app/oracle/TEST/users_01.dbf’;

alter database rename file ‘+DATA/test/datafile/users.309.697650601’ to ‘/app/oracle/TEST/users_02.dbf’;

3- This not the finish , there’s some file still On A, Check it by :

open database

select name from v$controlfile
union
select name from v$tempfile
union
select member from v$logfile
union
select filename from v$block_change_tracking;

NAME
——————————————————————————–
+DATA/test/controlfile/current.303.697650047
+DATA/test/onlinelog/group_1.304.697650049
+DATA/test/onlinelog/group_2.305.697650049
+DATA/test/onlinelog/group_3.306.697650049
+DATA/test/tempfile/temp.307.697650095
+FRA/test/controlfile/current.260.697650047
+FRA/test/onlinelog/group_1.261.697650049
+FRA/test/onlinelog/group_2.262.697650049
+FRA/test/onlinelog/group_3.263.697650051

alter database rename file ‘+DATA/test/datafile/sysaux.300.697649963’ to ‘/app/oracle/TEST/sysaux_01.dbf’;

alter database rename file ‘+DATA/test/datafile/system.299.697649963’ to ‘/app/oracle/TEST/system_01.dbf’;

alter database rename file ‘+DATA/test/datafile/undotbs1.301.697649965’ to ‘/app/oracle/TEST/undotbs1_01.dbf’;

alter database rename file ‘+DATA/test/datafile/users.302.697649965’ to ‘/app/oracle/TEST/users_01.dbf’;

alter database rename file ‘+DATA/test/datafile/users.309.697650601’ to ‘/app/oracle/TEST/users_02.dbf’;

ALTER DATABASE ADD LOGFILE GROUP 4 (‘/app/oracle/TEST/redo_04a.dbf’,’/app/oracle/TEST/redo_04b.dbf’) size 50M;

ALTER DATABASE ADD LOGFILE GROUP 5 (‘/app/oracle/TEST/redo_05a.dbf’,’/app/oracle/TEST/redo_05b.dbf’) size 50M;

ALTER DATABASE ADD LOGFILE GROUP 6 (‘/app/oracle/TEST/redo_06a.dbf’,’/app/oracle/TEST/redo_06b.dbf’) size 50M;

4-the Last Step for Control file and Spfile :

SQL>show parameter control

control_files

————————–

+DATA/test/controlfile/current .303.697650047

SQL > Create Pfile=” from spfile ;

After Creating Pfile , Open it modify Control File Location to Our New Location /app/oracle/TEST/…

*.control_files=’/app/oracle/TEST/control01.ctl’,’/app/oracle/TEST/control02.ctl’

startup nomount

$rman target /

restore controlfile from ‘+DATA/test/controlfile/current.303.697650047’;

exit

create spfile=’/app/oracle/product/11.1.0/db_1/dbs/spfileTEST.ora’ from pfile=’/home/oracle/john.ora’;

File created.

shutdown immediate;
startup

show parameter control

control_files /app/oracle/TEST/control01.ctl , /app/oracle/TEST/control02.ctl

This Steps Without Using RMAN , I will Post Another Steps Using RMAN
