Oracle错误日志：11gR2 RAC升级后启动报ORA-01565,ORA-17503,ORA-

AIX平台下，Oracle 11G RAC，从11.2.0.2升级到11.2.0.3后，数据库启动失败，报错如下：

[Oracle@p520]$sqlplus "/as sysdba"
SQL*Plus: Release 11.2.0.3.0 Production on Fri Apr 6 12:04:52 2012
Copyright (c) 1982, 2011, Oracle.  All rights reserved.-
 

Connected to an idle instance.
SQL> startup;
ORA-01078: failure in processing system parameters
ORA-01565: error in identifying file '+SYSTEMDG/racdb/spfileracdb.ora'
ORA-17503: ksfdopn:2 Failed to open file +SYSTEMDG/racdb/spfileracdb.ora
ORA-12547: TNS:lost contact

经检查，ASM实例启动正常，diskgroup mount正常。

最终确定这个问题是因为bin/Oracle权限引起，解决方法如下：

Oracle binary should have permission of 6751. To correct the permission, as owner of oracle binary:
cd $GRID_HOME/bin
chmod 6751 Oracle
cd $Oracle_HOME/bin
chmod 6751 Oracle
After the change, permission should show:
[Oracle@p520]/oracle/app/oracle/product/11.2.0/dbs $ls -al $ORACLE_HOME/bin/oracle
-rwsr-s--x    1 Oracle   asmadmin  300821572 Apr 06 11:00 /oracle/app/oracle/product/11.2.0.3/bin/oracle
Once the permission is fixed, if database still fails to come up, restart Grid Infrastructure.
