Nebackup and Rac one node

remsma
Level 2

We  use netbackup version 8 to backup Oracle Rac Onde Node (include 3 nodes) version 12.2.0 Cluster database on linux, we have configured the netbackup policies to backup

 We use vip adress not scan adress. The database is relocated at the moment  on node1.

When we excute rman command netbackup we get failed on node2 and nod3

 RUN {

 ALLOCATE CHANNEL A01 TYPE 'SBT_TAPE' PARMS 'ENV=(NB_ORA_CLIENT=nod1-vip.xx.se)' CONNECT 'yz/yz@PVIP1 as sysbackup';

You should probably change this to be unique for node two and three.

CONNECT 'yz/yz@PVIP1

eg

CONNECT 'yz/yz@PVIP2
CONNECT 'yz/yz@PVIP3

Hi

Thanks. I changed to be unique for node two and there. I get the same errors.

Ensure /etc/hosts on all three nodes have correct IP address of master & media server and you can ping through the interface that is being used for the backups (if you are not using primary interface for backup).

Please run following command from master and media server for each of the nodes

bptestbpcd -client node_name -verbose

Please run following command from all three nodes

bpclntcmd -pn

I am not Oracle RAC expert, but this statement says to be backup is probably not load balanced? 

 The database  relocated at the moment  on node1. 
When we excute rman command netbackup we get failed on node2 and nod3

Maybe this section of the manual might help?

The backup script should be customized so that it starts RMAN on exactly one
of the clients. If the script is executed on the primary, then start RMAN and
perform the backup. If the script is executed on the secondary and the primary
is up, then exit with status 0 so the NetBackup scheduler doesn't retry this client.
If the script is executed on the secondary and the primary is down, then start
RMAN and perform the backup. You can build the script customization around
a tnsping to the primary or even a query of the database. Use this customization
to see if the other instance is open and able to perform the backup.

(See NBU for Oracle manual for more info... )

Hi
Thanks very much for your response. We will try to apply your suggestion if we will not be applicable to use scan adress instead.

We use scan adress for connecting to database, when we try to use backup script using allocate channne disk and scan adress, we get no errors, everything executed succeffully.

When we use netbackup. However when trying to connect, the connection to the node is random due to the nature of RAC. When the backup starts, the check is failing, resulting in a somewhat wrong error message of the client. Netbackup version 8.

Is something missing.... In netbackupVersion 8 or  we need to complete some api...?????

connect target xxx/yyyy@SCAN_ADRESS as sysdba
connect catalog xyxy/xyxx@RMAN

RUN {

ALLOCATE CHANNEL A01 TYPE 'SBT_TAPE' PARMS 'ENV=(NB_ORA_CLIENT=scan_adress.xx.se)' ;

ALLOCATE CHANNEL A02 TYPE 'SBT_TAPE' PARMS 'ENV=(NB_ORA_CLIENT=scan_adress.xx.se)' ;

SEND 'NB_ORA_SERV=netbackup-master1,NB_ORA_POLICY=hot_policy';

Hi,

There are 5 different way you can configure the policy for RAC in NBU.
