BRRESTORE from Networker software: ORACLE DATABASE.

BRRESTORE from Networker software: ORACLE DATABASE.

https://wrongcodes.blogspot.com/2018/04/brrestore-from-emc-networker-and.html

Scenario explaining how to restore using backup from EMC DD& Netwroker using BRrestore. Database should be backed up using backnit tools from EMC. The backup should be completed successfully at the application level as well as database level. User can check the backup status using TXN db12 and verify the status.

Source system and target system should be the same database and patch level as well OS also. (recommended) try to keep the same drive as source system.

On the target machine EMC networker backup should be configure and backed up before restoring the source.

STEP1:

initSID.utl File must be created while configuring the backup to the target machine. Edit the “initSID.utl” file and add the following parameter. Normally the file located in to % ORACLE_HOME% database folder

NSR_NWPATH = C:\Program Files\EMC NetWorker\nsr\bin\

NSR_DEVICE_INTERFACE=DATA_DOMAIN

NSR_RECOVER_POOL = GEP2018

client = eccsapgrp.TEST.local

server = backupsrvr.TEST.local

debug_level=9

verbose=TRUE

#NSR_DPRINTF=TRUE

Above parameter details:

NSR_NWPATH= networker installed path in target machine

NSR_RECOVER_POOL = source system data backup pool

Client= sources system hostname FQN if configured.

Server = networker backup server(media server)

Save the file after adding the parameter, in to same location.File should have read and write access to the ora_dba user and sapSIDadm user.

TOTAL FILE details below.

###########################################################################

#

# This is the .utl file.

#

# This file contains settings for the NetWorker Module for SAP with

# Oracle (a.k.a. NMSAP).

#

# Note: Comments have a “#” in the first column.

#

###########################################################################

# Default Value: 8

# Valid Values: > 0 integer

# Number of simultaneous savesets/savestreams to send to server.

# Be sure your server and devices are configured to support at least

# as many streams.

#

# parallelism = 8

parallelism = 30

# Default Value: no

# Valid Values: no/yes

# Group saveset by file system

# If set to ‘yes’, savesets parameter will be ignored

#

# ss_group_by_fs = yes

ss_group_by_fs = FALSE

# Additional configuration options.

# These are optional fields.

#

NSR_NWPATH = C:\Program Files\EMC NetWorker\nsr\bin\

NSR_DEVICE_INTERFACE=DATA_DOMAIN

NSR_RECOVER_POOL = GEP2018

client = eccsapgrp.geepas.local

server = backupsrvr.geepas.local

debug_level=9

verbose=TRUE

#NSR_DPRINTF=TRUE

STEP 2:

Copy xxx.anf file to the %sapdata_home%\sapbackup. .anf file either located in to source system %sapdata_home%\sapbackup – folder or into the backup location where you backed up last backup.

Brrestore will perform the restore based on .anf file.

Once place the .anf file into the sapbackup folder open cmd with administrative right and run the below scrip:

You must edit the script based on the file location and .anf file name.

brrestore -p C:\oracle\GEP\102\database\initGEP.sap -d util_file -r C:\oracle\GEP\102\database\initGEP.utl -m full -b beybvnzl.anf -m full -m all=X:\restore -c force

Above script I am restoring all 6TB database data file in to the X: drive\restore folder. In this scenario all data file will be restored into the X:\restore folder without parent and subfolder. Once restore complete you can see the logs into the same sapbackup folder with file extension .rsb.

Once all data file completely restored into the drive you need to restore archive logs from the backup location.

STEP3:

After that create control file using control file script.
