CRS-5017: The resource action "ora.cdb1.db start" encountered the following error:
ORA-01017: invalid username/password; logon denied
. For details refer to "(:CLSN00107:)" in "/u01/app/grid/diag/crs/multisrv1/crs/trace/ohasd_oraagent_grid.trc".

CRS-2674: Start of 'ora.cdb1.db' on 'multisrv1' failed
ORA-01017: invalid username/password; logon denied

Cause:

grid user is not under dba group.

[root@multisrv1 ~]# id grid
uid=54323(grid) gid=54321(oinstall) groups=54321(oinstall),492(vboxsf),54323(asmadmin),54324(asmdba)

Solution:

Add grid user to dba group and relink the oracle binary

 
[root@multisrv1 ~]# usermod -a -G dba grid
[root@multisrv1 ~]# id grid
uid=54323(grid) gid=54321(oinstall) groups=54321(oinstall),54322(dba),492(vboxsf),54323(asmadmin),54324(asmdba)

[oracle@multisrv1 bin]$ ./relink all
writing relink log to: /u01/app/oracle/product/12.2.0.1/db_1/install/relink.log
[oracle@multisrv1 bin]$
