oracle 数据库启动失败，报下面的错误

srvctl start database -d ora11g
PRCR-1079 : Failed to start resource ora.ora11g.db
ORA-12547: TNS:lost contact
CRS-5017: The resource action "ora.ora11g.db start" encountered the following error:

. For details refer to "(:CLSN00107:)" in "/u01/app/11.2.0/grid/log/x3850/agent/ohasd/oraagent_grid/oraagent_grid.log".

CRS-2674: Start of 'ora.ora11g.db' on 'x3850' failed

请检查oracle执行文件的权限

[root@x3850 ~]# which oracle
/u01/app/11.2.0/grid/bin/oracle
[root@x3850 ~]# ls -al /u01/app/11.2.0/grid/bin/oracle
-rwsr-s--x 1 grid oinstall 209914513 Nov 6 13:41 /u01/app/11.2.0/grid/bin/oracle
[root@x3850 ~]# su - oracle
[oracle@x3850 ~]$ which oracle
/u01/app/oracle/11.2.0/db/bin/oracle
[oracle@x3850 ~]$ ls -al /u01/app/oracle/11.2.0/db/bin/oracle
-rwxr-s--x 1 oracle asmadmin 228335347 Nov 6 14:04 /u01/app/oracle/11.2.0/db/bin/oracle

正常情况下oracle目录下的oracle的权限应该是和-rwsr-s--x 一样的

修改权限，启动成功

[oracle@x3850 ~]$ chmod 6751 /u01/app/oracle/11.2.0/db/bin/oracle
[oracle@x3850 ~]$ exit
logout
[root@x3850 ~]# srvctl start database -d ora11g
[root@x3850 ~]# crs_stat -t
