Overview of New PULL method

The original “push” process is based on image copies.With Oracle Database 12c, a “pull” (or restore) process is based on backup sets. A connection is first established with the source database. The auxiliary instance then retrieves the required database files from the source database as backup sets. A restore operation is performed from the auxiliary instance instance. Therefore, fewer resources are used on the source database.

Both TNS connections are required on target and auxiliary instances.Based on the DUPLICATE clauses, RMAN dynamically determines which process to use (push or pull’. This ensures that existing customized scripts continue to function.

  • When you specify USING BACKUPSET, RMAN uses the pull method.

  • When you specify SET ENCRYPTION before the DUPLICATE command, RMAN

automatically uses the pull method and creates backup sets. The backups sent to the destination are encrypted.

  • The SECTION SIZE clause divides data files into subsections that are restored in parallel across multiple channels on the auxiliary database. For an effective use of parallelization, allocate more AUXILIARY channels.

  • With the USING COMPRESSED BACKUPSET clause, the files are transferred as compressed backup sets. RMAN uses unused block compression while creating backups,thus reducing the size of backups that are transported over the network.

NOOPEN

You might duplicate a database with RMAN for various reasons. In earlier versions a recovered duplicated database was automatically opened. By default, this functionality continues with the Oracle Database 12c.
What is new is that you have an option to finish the duplication process with the database in a mounted, but not opened state. This is useful when the attempt to open the database would produce errors and in all cases when you want to modify initialization settings, which are otherwise quite difficult to modify.
For example, you may want to move the location of the database to ASM. Also when you are performing an upgrade, where the database must not be open with resetlogs, prior to running upgrade scripts.
The NOOPEN option allows the duplication to create a new database as part of an upgrade procedure and leaves the database in a state ready for opening in upgrade mode and subsequent execution of upgrade scripts.

Multi-section now is available on image copy.

 

Active duplication step

Create init parameter file from source and change relevant parameters like control_file,db_name etc.I have provided below sample of init.ora.

[oracle@rac1 dbs]$ cat initrcat.ora
*._catalog_foreign_restore=FALSE
*.audit_file_dest=’/u01/app/product/admin/rcat/adump’
*.audit_trail=’db’
*.compatible=’12.1.0.2.0′

*.db_block_size=8192
*.db_create_file_dest=’+DATA’
*.db_domain=”
*.db_name=’rcat’
*.db_recovery_file_dest=’+DATA’
*.db_recovery_file_dest_size=4785m
*.diagnostic_dest=’/u01/app/product’
*.dispatchers='(PROTOCOL=TCP) (SERVICE=rcatXDB)’
*.enable_pluggable_database=true
*.open_cursors=300
*.optimizer_adaptive_features=FALSE
*.parallel_max_servers=8
*.parallel_min_servers=0
*.pga_aggregate_target=570m
*.processes=300
*.remote_login_passwordfile=’exclusive’
*.session_cached_cursors=1000
*.sga_target=1710m
*.shared_pool_size=629145600
*.undo_tablespace=’UNDOTBS1′

 

Create required audit directory in target

mkdir -p /u01/app/product/admin/rcat/adump

Add entry as static listener.ora under $GRID_HOME/network/admin

SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = rcat)
(ORACLE_HOME = /u01/app/product/ora12c/12.1.0/dbhome_1)
(GLOBAL_DBNAME = rcat)
)
)

Add corresponding entry in tnsnames.ora

[oracle@rac1 admin]$ cat tnsnames.ora
# tnsnames.ora Network Configuration File: /u01/app/product/ora12c/12.1.0/dbhome_1/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.

############Source###################

ORCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = rac-scan)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
)
)

 

#######Target#################
RCAT =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.56.101)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = rcat)
(UR=A)
)
)

 

The (UR=A) clause for TNS connect strings was created in response to an enhancement request.
This clause can be inserted into the “(CONNECT_DATA=” section of a TNS connect string and allow a privileged or administrative user to connect via the listener even when the service handler is blocking connections for non-privileged users. This feature is introduced since Oracle 10g

If UR=A is not added,you will get following error during connection to target in nomount state in next steps:-

ORA-12528: TNS:listener: all appropriate instances are blocking new connections

Create password file

cd $ORACLE_HOME/dbs

orapwd file=orapwrcat password=oracle

Now start target database in nomount

export ORACLE_SID=rcat

Create password file in ASM now

Create spfile.

Now add database in srvctl

srvctl add database -db rcat -oraclehome $ORACLE_HOME
srvctl modify database -db rcat -pwfile +DATA/pwdrcat.ora
srvctl modify database -db rcat -spfile +DATA/spfilercat.ora

Issue faced:-

RMAN-11003: failure during parse/execution of SQL statement: alter system set db_unique_name = ‘RCAT’ comment= ‘Modified by RMAN duplicate’ scope=spfile
ORA-32017: failure in updating SPFILE
ORA-65500: could not modify DB_UNIQUE_NAME, resource exists

Please remove the database from srvctl if already added before duplicate

[oracle@rac1 dbs]$ srvctl remove database -d rcat
