Client name is same. bplist listing backups with root user but not with oracle user.

I have taken backup with "oratest" user & trying to restore as "oracle"

How we can restore with different user?

Please advice.

Regards.

Try adding the "oratest" GID to the "oracle" user.

Most of my experiences with lack of permissions in Oracle restores were solved by giving the restore user permissions similar to the backup user. Adding the restore user to the same group the backup user uses in the Oracle directories worked for me.

Hello,

Run the below command on client server. This command will list all control, archive and databasse files.

#/usr/openv/netbackup/bin/bplist -C (source client name) -t 4 -R -l /

The default control file name e.g /cntrl_624_1_77000xxxx

Run the below command with correct control file. /cntrl_624_1_770006541

RMAN> run
2> {
3> ALLOCATE CHANNEL aux1 DEVICE TYPE SBT_TAPE PARMS="SBT_LIBRARY=/usr/openv/netbackup/bin/libobk.so64.1, ENV=(NB_ORA_CLIENT=edwdrac1,NB_ORA_SERV=HPLIB)";
4> restore controlfile from cntrl_624_1_xxxxxx.;
5> }

The mount the database and the perform backup and recovery.

User permissions to backup images are set at time of backup.
It cannot be changed afterwards. 
If not explicitly set, then the default permissions are 660.
This means that same user and anyone belonging to same group can read the backups.

This is covered in NBU for Oracle manual: 

Options for the SEND command
BKUP_IMAGE_PERM
Lets you set the permissions on a backup image at backup
time. Possible values are the following:
USER - set the permissions to 600. Only the original user
who backed up the data has access to the backup images.
GROUP - set the permissions to 660. Anyone from the
same group as the original user who backed up the data
has access to the backup images.
ANY - set the permissions to 664. Anyone has access to
the backup images.

So, as per @Alexis_Jeldrez you need to add oracle user to same group as oratest. (A user can belong to more than one group.)
bplist  with -l option will show user and group.
