Oracle user cannot write to ASM DATA diskgroup after succesful installation of grid infra in 11.2

Problem:

While restoring controlfile to test environment, from filesystem or tape environment after installing grid infrastructure.

I got following errors from both RMAN  and DBCA, despite the fact that I could create directory alias in asmcmd.

RMAN> run {

2> allocate channel t1 device type 'SBT_TAPE'

3> parms 'ENV=(NSR_SERVER=bcksrv1, NSR_CLIENT=mydb, NSR_DATA_VOLUME_POOL=JB10)';

4> RESTORE controlfile to '+DATA' FROM '/tmp/ctl01.dbf';

5> release channel t1 ;

6> }

allocated channel: t1

channel t1: SID=386 device type=SBT_TAPE

channel t1: NMO v5.0.0.0

Starting restore at 29-MAY-12

released channel: t1

ORA-19600: input file is control file  (/tmp/ctl01.dbf)

ORA-19601: output file is control file  (+DATA)

Cause:

Access rights to oracle disk.

Solution:

I checked the asm disks. /dev/rdsk/disk * has grid:oinstall ownership.

Grid infra home and bin has grid:oinstall, while the oracle home and bin has oracle:oinstall, as told in the MOS.

In our case, access rights on disk device files, are not 77x. As the second 7 means access to group oinstall.

I changed the access rights to 777 and it worked.
