环境介绍：
Linux5，OracleRAC 11.2.0.1 to 11.2.0.3
AIX6.1，，OracleRAC 11.2.0.1 to 11.2.0.3
升级DB HOME到11.2.0.3后，启动Oracle遇到ORA-00600报错：
ORA-00600: internal error code, arguments: [kfioTranslateIO03]
ORA-00600: internal error code, arguments: [17090]
原因是由权限引起，解决方法 [ID 1336846.1]，如下：
Applies to:
Oracle Server - Enterprise Edition - Version: 11.2.0.2 and later [Release: 11.2 and later ]
Information in this document applies to any platform.
Symptoms
In 11.2.0.2 where role separation between GRID and RDBMS is implemented, the following ORA-600 error prevents database from starting up.
ORA-00600: internal error code, arguments: [kfioTranslateIO03]
ORA-00600: internal error code, arguments: [17090]
Cause
group permission of "oracle" executable from RDBMS home should have the same group information for ASM devices according to note 1084186.1.
$ ls -l $GRID_HOME/bin/oracle
-rwsr-s--x 1 grid oinstall 228954465 Jul 1 13:37 /oh1/grid/product/11.2.0/bin/oracle
$ ls -l $RDBMS_HOME/bin/oracle
-rwsr-s--x 1 oracle asmadmin 228954465 Jul 1 13:37 /oh1/oracle/product/11.2.0/bin/oracle
$ ls -l $ASM_DEVICE/*
brw-rw---- 1 grid asmadmin 8, 33 Feb 15 08:11 /dev/oracleasm/disks/ASMD1
brw-rw---- 1 grid asmadmin 8, 49 Feb 15 08:11 /dev/oracleasm/disks/ASMD2
brw-rw---- 1 grid asmadmin 8, 17 May 4 22:30 /dev/oracleasm/disks/CRSD1
But in this case, "oracle" executable from RDBMS shows different group information which is different from group information for ASM devices.
ORA-600[kfioTranslateIO03] and [17090] occurrs due to the permission issue.
$ ls -l $RDBMS_HOME/bin/oracle
-rwsr-s--x 1 oracle oinstall 228954465 Jul 1 13:37 /oh1/oracle/product/11.2.0/bin/oracle
^^^^^^^ it should be "asmadmin" or at least should be the same group of all ASM devices.
Solution
group information for $RDBMS_HOME/bin/oracle should be changed to the group that can read/write to ASM devices.
Please execute the following action plan from note 1084186.1.
$ su - grid
$ cd /bin
$ ./setasmgidwrap o=/bin/oracle
