Hot Backup clone without using RMAN

Hot Backup clone without using RMAN
I wish to create details steps  " how to clone database without using RMAN in hotbackup mode"

SQL> conn tom/tom
Connected.
SQL> select * from tab;

1. Make sure the database is in archive log mode
SQL> archive log list;                  
Database log mode              Archive Mode
Automatic archival             Enabled
Archive destination            /u01/app/oracle/oradata/jetway/jatway/arch
Oldest online log sequence     40
Next log sequence to archive   42
Current log sequence           42

2. Make a note of the current archive log change number
Because the restored files will require recovery, some archive logs will be needed.
This applies even if you are not intending to put the cloned database into archive log mode.
Work out which will be the first required log by running the following query on the source database.
Make a note of the change number that is returned:

SQL> select max(first_change#) Latest_chng from v$archived_log;

LATEST_CHNG
-----------
    1134000


3. View the current location of the data files

SQL> Select tablespace_name, file_name from dba_data_files order by 1;
SAMTBS1                        /u01/app/oracle/oradata/jetway/jatway/samtbs01.dbf
SYSAUX                         /u01/app/oracle/oradata/jetway/jatway/sysaux01.dbf
SYSTEM                         /u01/app/oracle/oradata/jetway/jatway/system01.dbf
UNDOTBS1                       /u01/app/oracle/oradata/jetway/jatway/undotbs01.dbf
USERS                          /u01/app/oracle/oradata/jetway/jatway/users01.db

4. Check whether the data files are in backup mode or not

SQL> SELECT t.name, d.file# as, b.status FROM V$DATAFILE d, V$TABLESPACE t, V$BACKUP b WHERE d.TS#=t.TS# AND b.FILE#=d.FILE#;


SELECT t.name, d.file# as, b.status
FROM V$DATAFILE d, V$TABLESPACE t, V$BACKUP b
WHERE d.TS#=t.TS# AND b.FILE#=d.FILE#;  2    3



NAME                                FILE# STATUS
------------------------------ ---------- ------------------
SYSTEM                                  1 NOT ACTIVE
SYSAUX                                  2 NOT ACTIVE
UNDOTBS1                                3 NOT ACTIVE
USERS                                   4 NOT ACTIVE
SAMTBS1                                 5 NOT ACTIVE

The above result shows that the data files are not in backup mode

5. Generate a script to bring the data file in backup mode using the following command:

SQL> !pwd
/home/oracle

[oracle@sfo ~]$ cd /home/oracle/
[oracle@sfo ~]$ vi enable_hotbackup_mode.sql


set lines 999 pages 999
set verify off
set feedback off
set heading off

spool begin_backup.sql

select 'alter tablespace ' || tablespace_name || ' begin backup;' tsb_backup_mode
from    dba_tablespaces
where   contents != 'TEMPORARY'
order by tablespace_name
/
spool off

SQL> @enable_hotbackup_mode.sql

alter tablespace SAMTBS1 begin backup;
alter tablespace SYSAUX begin backup;
alter tablespace SYSTEM begin backup;
alter tablespace UNDOTBS1 begin backup;
alter tablespace USERS begin backup;

(or) -- if you do not want a particular tablespace in backup mode,
the entire database can be brought to backup mode using the following command


SQL>alter database begin backup;

SQL> SELECT t.name, d.file# as, b.status FROM V$DATAFILE d, V$TABLESPACE t, V$BACKUP b WHERE d.TS#=t.TS# AND b.FILE#=d.FILE#;

SYSTEM                                  1 ACTIVE
SYSAUX                                  2 ACTIVE
UNDOTBS1                                3 ACTIVE
USERS                                   4 ACTIVE
SAMTBS1                                 5 ACTIVE

The above result shows all the tablespaces with backup mode enabled

6. Check the database using server parameter file

SQL> show parameter spfile;

spfile                               string      /u01/app/oracle/product/11.2.0
                                                 /dbhome_1/dbs/spfilejatway.ora

7. The below steps helps to bring individual tablespaces out of backup mode

SQL> alter tablespace SAMTBS1 end backup;

a)

SQL> alter tablespace SAMTBS1 end backup;
SQL> SELECT t.name, d.file# as, b.status FROM V$DATAFILE d, V$TABLESPACE t, V$BACKUP b WHERE d.TS#=t.TS# AND b.FILE#=d.FILE#;

SYSTEM                                  1 ACTIVE
SYSAUX                                  2 ACTIVE
UNDOTBS1                                3 ACTIVE
USERS                                   4 ACTIVE
SAMTBS1                                 5 NOT ACTIVE

b)

SQL> alter tablespace SYSTEM end backup;
SQL> SELECT t.name, d.file# as, b.status FROM V$DATAFILE d, V$TABLESPACE t, V$BACKUP b WHERE d.TS#=t.TS# AND b.FILE#=d.FILE#;

SYSTEM                                  1 NOT ACTIVE
SYSAUX                                  2 ACTIVE
UNDOTBS1                                3 ACTIVE
USERS                                   4 ACTIVE
SAMTBS1                                 5 NOT ACTIVE

c)

SQL> alter tablespace SYSAUX end backup;
SQL> SELECT t.name, d.file# as, b.status FROM V$DATAFILE d, V$TABLESPACE t, V$BACKUP b WHERE d.TS#=t.TS# AND b.FILE#=d.FILE#;

SYSTEM                                  1 NOT ACTIVE
SYSAUX                                  2 NOT ACTIVE
UNDOTBS1                                3 ACTIVE
USERS                                   4 ACTIVE
SAMTBS1                                 5 NOT ACTIVE

d)

SQL> alter tablespace UNDOTBS1 end backup;
SQL> SELECT t.name, d.file# as, b.status FROM V$DATAFILE d, V$TABLESPACE t, V$BACKUP b WHERE d.TS#=t.TS# AND b.FILE#=d.FILE#;

SYSTEM                                  1 NOT ACTIVE
SYSAUX                                  2 NOT ACTIVE
UNDOTBS1                                3 NOT ACTIVE
USERS                                   4 ACTIVE
SAMTBS1                                 5 NOT ACTIVE

e)

SQL> alter tablespace USERS end backup;
SQL> SELECT t.name, d.file# as, b.status FROM V$DATAFILE d, V$TABLESPACE t, V$BACKUP b WHERE d.TS#=t.TS# AND b.FILE#=d.FILE#;

SYSTEM                                  1 NOT ACTIVE
SYSAUX                                  2 NOT ACTIVE
UNDOTBS1                                3 NOT ACTIVE
USERS                                   4 NOT ACTIVE
SAMTBS1                                 5 NOT ACTIVE

8. The following query can also be used to find whether the tablespaces is in backup mode or not

SQL> Select * from v$backup;

         1 NOT ACTIVE            1179330 25-SEP-12
         2 NOT ACTIVE            1179330 25-SEP-12
         3 NOT ACTIVE            1179330 25-SEP-12
         4 NOT ACTIVE            1179330 25-SEP-12
         5 NOT ACTIVE            1179330 25-SEP-12

9. Copy the following tablespaces to the clone location (except the temp tablespace)
I am moving all the files to the "backup" folder

SQL> Select tablespace_name, file_name from dba_data_files order by 1;
SAMTBS1                        /u01/app/oracle/oradata/jetway/jatway/samtbs01.dbf
SYSAUX                         /u01/app/oracle/oradata/jetway/jatway/sysaux01.dbf
SYSTEM                         /u01/app/oracle/oradata/jetway/jatway/system01.dbf
UNDOTBS1                       /u01/app/oracle/oradata/jetway/jatway/undotbs01.dbf
USERS                          /u01/app/oracle/oradata/jetway/jatway/users01.db

[oracle@sfo backup]$ pwd
/u01/app/oracle/oradata/jetway/jatway/backup
[oracle@sfo backup]$ ls
initclohot.ora  samtbs01.dbf  sysaux01.dbf  system01.dbf  undotbs01.dbf  users01.dbf

10. Create the TAR file of the copied tablesapces. To avoid future errors I am creating another
copy of the tablespace backup folder and moving across the clone location


[oracle@sfo jatway]$ cp -r backup backup01
[oracle@sfo jatway]$ ls
arch  backup  backup01  backupinitclohot.ora  control01.ctl  redo01.log  redo02.log  redo03.log  redo04.log  redo05.log  redo06.log  redo07.log  samtbs01.dbf  sysaux01.dbf  system01.dbf  temp01.dbf  undotbs01.dbf  users01.dbf
[oracle@sfo jatway]$ tar -cvzf backup.tar.gz backup01
backup01/
backup01/system01.dbf
backup01/control01.ora
backup01/sysaux01.dbf
backup01/initclohot.ora
backup01/samtbs01.dbf
backup01/undotbs01.dbf
backup01/users01.dbf
backup01/1_41_793069279.dbf
[oracle@sfo jatway]$

[oracle@sfo jatway]$ ls
arch    backup01              backup.tar.gz  redo01.log  redo03.log  redo05.log  redo07.log    sysaux01.dbf  temp01.dbf     users01.dbf
backup  backupinitclohot.ora  control01.ctl  redo02.log  redo04.log  redo06.log  samtbs01.dbf  system01.dbf  undotbs01.dbf
[oracle@sfo jatway]$ scp backup.tar.gz oracle@192.168.168.1:/u01/app/oracle/oradata

oracle@192.168.168.1's password:

backup.tar.gz                   100%  245MB  17.5MB/s   00:14
                                                                                                                                                                           100%  245MB  17.5MB/s   00:14

11. move the password file for the clone database across network

[oracle@sfo jatway]$

[oracle@sfo jatway]$ cd $ORACLE_HOME/dbs
[oracle@sfo dbs]$ ls orapw*
orapwdeccan  orapwdelta  orapwjatway
[oracle@sfo dbs]$ pwd
/u01/app/oracle/product/11.2.0/dbhome_1/dbs
[oracle@sfo dbs]$ scp orapwjatway oracle@192.168.168.1:/u01/app/oracle/product/11.2.0/db_1/dbs
oracle@192.168.168.1's password:
orapwjatway                                 100% 1536     1.5KB/s   00:00                                                                                                                                                                             100% 1536     1.5KB/s   00:00  
[oracle@sfo dbs]$

[oracle@sfo backup]$

12. Create a backup control file for the clone location and move across the clone location.
SQL> show parameter control

control_file_record_keep_time        integer     7
control_files                        string      /u01/app/oracle/oradata/jetway
                                                 /jatway/control01.ctl, /u01/ap
                                                 p/oracle/flash_recovery_area/j
                                                 atway/control02.ctl
control_management_pack_access       string      DIAGNOSTIC+TUNING


SQL>Alter database backup controlfile to trace as '/u01/app/oracle/oradata/jetway/jatway/backup/control01.ora';

[oracle@sfo backup]$ pwd
/u01/app/oracle/oradata/jetway/jatway/backup
[oracle@sfo backup]$ ls
control01.ora  initclohot.ora  samtbs01.dbf  sysaux01.dbf  system01.dbf  undotbs01.dbf  users01.dbf
[oracle@sfo backup]$

oracle@sfo dbs]$ scp control01.ora oracle@192.168.168.1:/u01/app/oracle/oradata/backup/control01.ora
oracle@192.168.168.1's password:
control01.ora                                 100% 1536     1.5KB/s   00:00


13. Copy archive logs for clone database
It is only necessary to copy archive logs created during the time the source database was in backup mode.
Begin by archiving the current redo: floow the step 2 to get archive log current.

SQL>alter system archive log current;


select name from v$archived_log where first_change# >= &change_no
order by name
/

Enter value for change_no: 1134000

/u01/app/oracle/oradata/jetway/jatway/arch/1_41_793069279.dbf

14. In the clone database location (name of the clone database is "clohot") and UNTAR the zip file

[oracle@nyc oradata]$cd /u01/app/oracle/oradata
[oracle@nyc oradata]$ ls
backup.tar.gz
[oracle@nyc oradata]$ ls
backup.tar.gz

[oracle@nyc oradata]$ tar -xvzf backup.tar.gz
backup01/
backup01/system01.dbf
backup01/control01.ora
backup01/sysaux01.dbf
backup01/initclohot.ora
backup01/samtbs01.dbf
backup01/undotbs01.dbf
backup01/users01.dbf
backup01/1_41_793069279.dbf

[oracle@nyc oradata]$


[oracle@nyc oradata]$ mv backup01 clohot/
[oracle@nyc oradata]$ ls -lrt
total 250916
drwxr-xr-x 4 oracle oinstall      4096 Sep  2 23:29 delta

15. Prepare the init parameter file for clone database("clohot")

Actul init parameter file
*.audit_file_dest='/u01/app/oracle/admin/jatway/adump'
*.audit_trail='db'

(note: My source database has dataguard so i am just database cone with archivelog and flashback enabled)

create the required dicectory as mentined in the parameter file
[oracle@nyc backup01]$ mkdir -p /u01/app/oracle/admin/clohot/adump
[oracle@nyc backup01]$ mkdir -p /u01/app/oracle/oradata/clohot

16. Modify the parameter as per the clone database base directory setup and add entry in /etc/oratab

19. using following points you can create the control file script
The file will require extensive editing before it can be used. Using your favourite editor make the following alterations:

    Remove any lines that start with '#', '--',

    Remove any blank lines in the 'CREATE CONTROLFILE' section and 'RECOVER DATABASE USING BACKUP CONTROLFILE' and 'ALTER DATABASE OPEN RESETLOGS;'

    Make a copy of the 'ALTER TABLESPACE TEMP...' lines, and then remove them from the file.
          Make sure that you hang onto the command, it will be used later.

   The word 'REUSE' needs to be changed to 'SET' and 'NORESETLOGS' changed to 'RESETLOGS'

    The database name needs setting to the new database name ("CLOHOT") (if it is being changed).
  
    Decide whether the database will be put into archivelog mode or not. IF YES USE "ARCHIVELOG", IF NO USE "NOARCHIVELOG"

    If the file paths are being changed, alter the file to reflect the changes.

20. changes are made as per the requirement

Oracle Database 10g Release 2 (10.2.0.1) Installation (RHEL5)

Oracle Database 10g Release 2 (10.2.0.1) Installation On Red Hat Enterprise Linux 5 (RHEL5)

In this article I'll describe the installation of Oracle Database 10g Release 2 (10.2.0.1) on Red Hat Enterprise Linux 5 (RHEL5). The article is based on a server installation similar to this, with a minimum of 2G swap, secure Linux disabled and the following package groups installed.

    GNOME Desktop Environment
    Editors
    Graphical Internet
    Text-based Internet
    Development Libraries
    Development Tools
    Legacy Software Development
    Server Configuration Tools
    Administration Tools
    Base
    Legacy Software Support
    System Tools
    X Window System

Alternative installations may require more packages to be loaded, in addition to the ones listed below.

    Download Software
    Unpack Files
    Hosts File
    Set Kernel Parameters
    Setup
    Installation
    Post Installation

Download Software

Download the following software.

    Oracle Database 10g Release 2 (10.2.0.1) Software

Unpack Files

Unzip the files.

    unzip 10201_database_linux32.zip

You should now have a single directory containing installation files. Depending on the age of the download this may either be named "db/Disk1" or "database".
Hosts File

The "/etc/hosts" file must contain a fully qualified name for the server.

    <IP-address>  <fully-qualified-machine-name>  <machine-name>

For example.

    127.0.0.1      localhost localhost.localdomain
    192.168.0.198  ol5-102.localdomain ol5-102

Set Kernel Parameters

Add the following lines to the "/etc/sysctl.conf" file.

    #kernel.shmall = 2097152
    #kernel.shmmax = 2147483648
    kernel.shmmni = 4096
    # semaphores: semmsl, semmns, semopm, semmni
    kernel.sem = 250 32000 100 128
    #fs.file-max = 65536
    net.ipv4.ip_local_port_range = 1024 65000
    net.core.rmem_default=262144
    net.core.rmem_max=262144
    net.core.wmem_default=262144
    net.core.wmem_max=262144

Run the following command to change the current kernel parameters.

    /sbin/sysctl -p

Add the following lines to the "/etc/security/limits.conf" file.

    *               soft    nproc   2047
    *               hard    nproc   16384
    *               soft    nofile  1024
    *               hard    nofile  65536

Add the following line to the "/etc/pam.d/login" file, if it does not already exist.

    session    required     pam_limits.so

Disable secure linux by editing the "/etc/selinux/config" file, making sure the SELINUX flag is set as follows.

    SELINUX=disabled

Alternatively, this alteration can be done using the GUI tool (System > Administration > Security Level and Firewall). Click on the SELinux tab and disable the feature.
Setup

Install the following packages.

    # From RedHat AS5 Disk 1
    cd /media/cdrom/Server
    rpm -Uvh setarch-2*
    rpm -Uvh make-3*
    rpm -Uvh glibc-2*
    rpm -Uvh libaio-0*
    cd /
    eject

    # From RedHat AS5 Disk 2
    cd /media/cdrom/Server
    rpm -Uvh compat-libstdc++-33-3*
    rpm -Uvh compat-gcc-34-3*
    rpm -Uvh compat-gcc-34-c++-3*
    rpm -Uvh gcc-4*
    rpm -Uvh libXp-1*
    cd /
    eject

    # From RedHat AS5 Disk 3
    cd /media/cdrom/Server
    rpm -Uvh openmotif-2*
    rpm -Uvh compat-db-4*
    cd /
    eject

Create the new groups and users.

    groupadd oinstall
    groupadd dba
    groupadd oper

    useradd -g oinstall -G dba oracle
    passwd oracle

Create the directories in which the Oracle software will be installed.

    mkdir -p /u01/app/oracle/product/10.2.0/db_1
    chown -R oracle.oinstall /u01

Login as root and issue the following command.

    xhost +<machine-name>

Edit the "/etc/redhat-release" file replacing the current release information (Red Hat Enterprise Linux Server release 5 (Tikanga)) with the following:

    redhat-4

Login as the oracle user and add the following lines at the end of the ".bash_profile" file.

    # Oracle Settings
    TMP=/tmp; export TMP
    TMPDIR=$TMP; export TMPDIR

    ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE

    CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib; export CLASSPATH

    if [ $USER = "oracle" ]; then
      if [ $SHELL = "/bin/ksh" ]; then
        ulimit -p 16384
        ulimit -n 65536
      else
        ulimit -u 16384 -n 65536
      fi
    fi

Installation

Log into the oracle user. If you are using X emulation then set the DISPLAY environmental variable.

    DISPLAY=<machine-name>:0.0; export DISPLAY

Start the Oracle Universal Installer (OUI) by issuing the following command in the database directory.

    ./runInstaller
