$ORACLE_HOME、GRID_HOME下oracle文件权限问题

原文链接： https://blog.csdn.net/wang_san_shi/article/details/44587385

1 涉及实例之间内部链接报错问题，大多数为oracle文件权限得问题。

2 /var/tmp/.oracle/目录权限得重要性，这个目录是所有进程socket文件所在目录，异常可以重启集群重建文件。

2、手动启动两个资源报错

[grid@rac1 ~]$ srvctl start asm -node rac1
PRCR-1013 : Failed to start resource ora.asm
PRCR-1064 : Failed to start resource ora.asm on node rac1
CRS-2674: Start of 'ora.asm' on 'rac1' failed

[grid@rac1 ~]$ srvctl start instance -d orarac -i orarac2
PRCR-1013 : Failed to start resource ora.orarac.db
PRCR-1064 : Failed to start resource ora.orarac.db on node rac2
CRS-5017: The resource action "ora.orarac.db start" encountered the following error:
ORA-01078: failure in processing system parameters
ORA-01565: error in identifying file '+DATA/orarac/spfileorarac.ora'
ORA-17503: ksfdopn:2 Failed to open file +DATA/orarac/spfileorarac.ora
ORA-01034: ORACLE not available
ORA-27123: unable to attach to shared memory segment
Linux-x86_64 Error: 13: Permission denied
Additional information: 2
Additional information: 12255236
. For details refer to "(:CLSN00107:)" in "/u01/app/grid/12.1.0/grid/log/rac2/agent/crsd/oraagent_oracle/oraagent_oracle.log".

CRS-2674: Start of 'ora.orarac.db' on 'rac2' failed

3、原因分析

查看权限设置发现：

[root@rac1 u01]# ll
total 36
drwxrwxr-x 4 oracle oinstall  4096 Mar 10 09:39 app
drwxr-xr-x 3 oracle oinstall  4096 Mar 23 15:55 backup
drwxrwxr-x 9 oracle oinstall  4096 Mar 13 08:34 gridbase
drwxrwxr-x 2 oracle oinstall 16384 Mar 10 09:13 lost+found
drwxrwxr-x 6 oracle oinstall  4096 Mar 12 10:42 oraInventory
drwxrwxr-x 3 oracle oinstall  4096 Mar 12 10:01 software

[root@rac2 u01]# ll
total 44
drwxrwxr-x 4 root   oinstall  4096 Mar 10 09:39 app
drwxr-xr-x 3 oracle oinstall  4096 Mar 23 15:57 backup
-rwxrwxr-x 1 oracle oinstall  8827 Mar 10 10:00 cvuqdisk-1.0.9-1.rpm
drwxrwxr-x 6 grid   oinstall  4096 Mar 11 15:59 gridbase
drwxrwxr-x 2 oracle oinstall 16384 Mar 10 09:35 lost+found
drwxrwxr-x 5 grid   oinstall  4096 Mar 12 10:42 oraInventory

由于大意修改了权限，导致问题的发生。

4、解决rac1上ASM无法启动的问题

修改rac1节点的文件夹权限，便可以启动ASM。

5、解决rac2上db无法启动的问题

CRS-5017: The resource action "ora.orarac.db start" encountered the following error:
ORA-01078: failure in processing system parameters
ORA-01565: error in identifying file '+DATA/orarac/spfileorarac.ora'
ORA-17503: ksfdopn:2 Failed to open file +DATA/orarac/spfileorarac.ora
ORA-01034: ORACLE not available
ORA-27123: unable to attach to shared memory segment
Linux-x86_64 Error: 13: Permission denied

从上面能看出是权限的问题，搜索ora-17503，找到解决办法（重设$GRID_HOME/bin/oracle文件的权限），分别在两个节点上执行：

[root@rac1 grid]# cd bin
[root@rac1 bin]# ls -la oracle
-rwxrwxrwx 1 oracle oinstall 263068997 Mar 11 15:21 oracle
[root@rac1 bin]# chown grid:oinstall oracle
[root@rac1 bin]# chmod 6751 oracle

[root@rac2 u01]# cd /u01/app/grid/12.1.0/grid
[root@rac2 grid]# cd bin
[root@rac2 bin]# ls -la oracle
-rwxrwxrwx 1 grid oinstall 263068997 Mar 11 15:22 oracle
[root@rac2 bin]# chmod 6751 oracle

之后启动正常。

最后还需要在两个节点确认权限(否则通过tns连接时可能出现ora-12537):

chmod 6751 /u01/app/oracle/product/12.1.0/dbhome_1/bin/oracle
