Description |
Command / Details / Screenshots |
|
1 |
Login to Source Database Srver and set oracle environment. |
. oraenv → TESTDB |
|
2 |
Create passwordfile if not already created. |
orapwd file=$ORACLE_HOME/dbs/orapw$ORACLE_SID password=”abc123″ format=12 force=y ls -1 $ORACLE_HOME/dbs/orapw$ORACLE_SID |
|
3 |
Send Passwordfile to destination server. |
scp orapwTESTDB oracle@192.168.0.198:/data/app/oracle/product/19C/dbhome/dbs/orapwTESTDB
|
|
4 |
Update tnsnames.ora file with both source and database connection string |
cd $ORACLE_HOME/network/admin vi tnsnames.ora TESTDB = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.197)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = TESTDB) ) ) CLONEDB = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.198)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = CLONEDB) ) ) |
|
5 |
Verify connection string |
tail -4 tnsnames.ora tnsping TESTDB tnsping CLONEDB |
On Destination Server:
|
6 |
Putty to Destination server with credentials |
|
|
7 |
Add CLONEDB database entry in oratab |
cat >> /etc/oratab << EOF CLONEDB:/data/app/oracle/product/19C/dbhome:N EOF # Verify ORACLE_SID is available in /etc/oratab file grep $ORACLE_SID /etc/oratab |
|
8 |
Add Static server in listener.ora file |
cd $ORACLE_HOME/network/admin vi listener.ora SID_LIST_LISTENER = (SID_LIST = (SID_DESC= (GLOBAL_DBNAME = CLONEDB) (ORACLE_HOME = /data/app/oracle/product/19C/dbhome) (SID_NAME = CLONEDB) ) ) |
|
9 |
Reload listener |
lsnrctl reload listener # Verify Service is registered lsnrctl status listener |grep $ORACLE_SID |
|
10 |
Set oracle environment to destination database. |
. oraenv → CLONEDB |
|
11 |
Update tnsnames.ora file with both source and database connection string cd $ORACLE_HOME/network/admin vi tnsnames.ora TESTDB = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.197)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = TESTDB) ) ) CLONEDB = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.198)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = CLONEDB) ) ) |
|
|
12 |
Verify connection string |
tail -4 tnsnames.ora tnsping TESTDB tnsping CLONEDB |
|
13 |
Make changes in init.ora to reflect new database name.Replace TESTDB to CLONEDB |
cd $ORACLE_HOME/dbs vi init$ORACLE_SID.ora DB_NAME=CLONEDB ESC :wq! |
|
14 |
Create all database directories for . |
[oracle@stand dbs]$ mkdir -p /data/app/oracle/admin/CLONEDB/adump [oracle@stand dbs]$ mkdir-p/data/app/oracle/oradata/CLONEDB [oracle@stand dbs]$ mkdir -p /data/app/oracle/oradata/CLONEDB [oracle@stand dbs]$ mkdir -p /data/app/oracle/oradata/CLONEDB [oracle@stand dbs]$ mkdir -p /data/app/oracle [oracle@stand dbs]$ mkdir -p /data/app/oracle/product/19C/dbhome/dbs/arch |
|
15 |
Startup database in nomount mode |
sqlplus / as sysdba startup nomount; exit; |
|
16 |
Connect to auxiliary instance with rman and start duplicating database rman target sys/abc123@TESTDB auxiliary sys/abc123@CLONEDB duplicate target database to CLONEDB from active database SPFILE parameter_value_convert (‘TESTDB’,’CLONEDB’) set log_archive_dest_1=’location=/data/app/oracle/product/19C/dbhome/dbs/arch’ NOFILENAMECHECK; exit; |
|
|
17 |
Verify database is up and running |
. oraenv → CLONEDB sqlplus / as sysdba col db_unique_name format a14 col created format a20 Select name, dbid, db_unique_name, to_char(created,’DD-MON-YY HH24:MI:SS’) as created from v$database; Select instance_name, status from v$instance; exit; |
