1.报错信息：

cnsh281177:t3fxqdb > sqlplus '/as sysdba'

2.修改config.c为正确属组并重编译：

cd $ORACLE_HOME/rdbms/lib

cp config.c config.c.bak

vi config.c

.section .rodata.str1.4, "aMS",@progbits,1

.align 4

.Ldba_string: .string "dba"

.Loper_string: .string "oinstall"

.Lasm_string: .string ""

.Lbkp_string: .string "dba"

.Ldgd_string: .string "dba"

.Lkmt_string: .string "dba"

#define SS_DBA_GRP "dba"

#define SS_OPER_GRP "oinstall"

#define SS_ASM_GRP ""

#define SS_BKP_GRP "dba"

#define SS_DGD_GRP "dba"

#define SS_KMT_GRP "dba"

rm config.o

make -f ins_rdbms.mk $ORACLE_HOME/rdbms/lib/config.o

relink all

3.确认oracle二进制文件权限

ls -al /paic/stg/oracle/rdbms/12c/12.1.0.2.170418_p32667073/bin/oracle

chown toracle:asmadmin /paic/stg/oracle/rdbms/12c/12.1.0.2.170418_p32667073/bin/oracle
