For the purposes of this post, the following environment is used as an example to describe the procedure:
Primary db_name and db_unique_name: BOSTON Standby db_name: BOSTON (same as primary db_name) Standby db_unique_name: CHICAGO Directory: /u01/app/oracle
Note: We cannot create a physical standby at PDB(plugable Database) level. It should be at CDB(Container Database) level i.e entire primary CDB should be cloned/created as physical Standby.
Steps includes:
- Create necessary Directory on standby server.
- Create pfile and password.
- Make static listener entry on standby server.
- Use RMAN Duplicate ..from Active Database to clone Primary CDB.
- Configure primary for remote log shipping and verify MRP progress on standby.
1. Create addition Directory on standby server:
$ mkdir -p /u01/app/oracle/admin/chicago/adump $ mkdir -p /u01/app/oracle/oradata/chicago $ mkdir -p /u01/app/oracle/fast_recovery_area/chicago $ mkdir -p /u01/app/oracle/oradata/chicago1/pdbseed $ mkdir -p /u01/app/oracle/oradata/chicago/db1
NOTE: Direcories like pdbseed,chicago1 are specific to 12c.
2. Create pfile:
$ echo 'db_name=boston' > /u01/app/oracle/product/12.1.0/dbhome_1/dbs/initchicago.ora
3. Create Password file or copy from primary:
$ orapwd file=/u01/app/oracle/product/12.1.0/dbhome_1/dbs/orapwchicago password=[password]
4. Make static listener entry:
$ cd $ORACLE_HOME/network/admin
$ vi listener.ora
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC=
(GLOBAL_DBNAME = chicago)
(ORACLE_HOME=/u01/app/oracle/product/12.1.0/dbhome_1)
(SID_NAME = chicago)
)
)
reload or restart listener.
$ lsnrctl stop $ lsnrctl start
5. Start the AUX instance at standby side.
$ sqlplus / as sysdba sql> startup nomount pfile='$ORACLE_HOME/dbs/initchicago.ora';
6. Initiate RMAN DUPLICATE from.. active database to create standby with target connected to primary instance.
$ rman target sys/[password]@boston auxiliary sys/[password]@chicago
run
{
allocate channel c1 type disk;
allocate channel c2 type disk;
allocate channel c3 type disk;
allocate channel c4 type disk;
allocate channel prim type disk;
allocate auxiliary channel aux type disk;
duplicate target database for standby from active database spfile
parameter_value_convert 'boston','chicago'
set db_file_name_convert='boston','chicago'
set log_file_name_convert='boston','chicago'
set log_archive_max_processes='10'
set db_unique_name='chicago'
set standby_file_management='AUTO'
set log_archive_config='dg_config=(boston,chicago)'
set log_archive_dest_1='location=USE_DB_RECOVERY_FILE_DEST valid_for=(all_logfiles,all_roles) db_unique_name=chicago'
set log_Archive_dest_2='service=boston async noaffirm reopen=15 valid_for=(all_logfiles,primary_role) db_unique_name=boston'
set log_archive_config='dg_config=(boston,chicago)';
sql channel aux "alter database add standby logfile ''/u01/app/oracle/oradata/chicago/stdbyredo1.log'' size 50M";
sql channel aux "alter database add standby logfile ''/u01/app/oracle/oradata/chicago/stdbyredo2.log'' size 50M";
sql channel aux "alter database add standby logfile ''/u01/app/oracle/oradata/chicago/stdbyredo3.log'' size 50M";
sql channel aux "alter database add standby logfile ''/u01/app/oracle/oradata/chicago/stdbyredo4.log'' size 50M";
sql channel prim "alter system archive log current";
sql channel aux "alter database recover managed standby database disconnect";
}

7. Prepare Primary database to ship REDO to standby.
a. Define log_archive_config value.
This parameter should have all the participating databases in the same DG configuration. Lets say this parameter tells about primary and all the participating standby(physical,logical,far sync) in DG configuration.
SQL> ALTER SYSTEM SET log_archive_config='dg_config=(boston,Chicago)' SCOPE=BOTH; System altered.
NOTE: log_archive_config value is not case sensitive.
b. Set remote log shipping.
@primary:
SQL>alter system set log_archive_dest_6='service=chicago async valid_for=(all_logfiles,primary_role) db_unique_name=chicago'; System altered.
NOTE: Here primary use ASYNC redo transport method to ship REDO to standby.
c. Verify redo log shipping,
SQL> alter system switch logfile; System altered.
SQL> col error for a30
SQL> select dest_id,error,status,log_sequence,applied_scn from v$archive_dest where dest_id=2;
DEST_ID ERROR STATUS LOG_SEQUENCE APPLIED_SCN
---------- ------------------------------ --------- ------------ -----------
2 VALID 63 2133221
8. Verify Standby is applying.
NOTE: MRP already started after the RMAN duplicate.
SQL> select process,status,thread#,sequence#,blocks from v#managed_standby where process like '%MRP%'; process status thread# sequence# blocks ------------- ---------------------- -------------- ------------- -------- MRP WAITING_FOR_LOG 1 64 0
