使用11gDNFS建立基於DNFS的tablespace

使用11gDNFS建立基於DNFS的tablespace

使用11g DNFS建立基於DNFS的tablespace

參考自：
Step by Step - Configure Direct NFS Client (DNFS) on Linux (11g) (文檔 ID 762374.1)

注意：
主機名p18的ip地址為192.168.80.18，是nfs的server
主機名為test179的為nfs的client

如下時操作過程：
一、在nfs server上的操作：

[root@p18 ~]# service nfs status
rpc.mountd is stopped
nfsd is stopped
rpc.rquotad is stopped
[root@p18 ~]# mkdir -p /u02/nfsdata
[root@p18 ~]# chown oracle:oinstall /u02/nfsdata
[root@p18 ~]# ls -ld /u02/nfsdata/
drwxr-xr-x 2 oracle oinstall 4096 Aug 17 07:22 /u02/nfsdata/

二、在nfs server上的操作：

[root@p18 nfsdata]# cat /etc/exports 
/u02/nfsdata *(rw,sync,all_squash,anonuid=500,anongid=502)
[root@p18 nfsdata]# 

三、在nfs server上的操作：

[root@p18 ~]# chkconfig --level 345 nfs on

四、啟動nfs server：

[root@p18 ~]# service nfs start
Starting NFS services:  [  OK  ]
Starting NFS quotas: [  OK  ]
Starting NFS daemon: [  OK  ]
Starting NFS mountd: [  OK  ]
[root@p18 ~]# exportfs -v
/u02/nfsdata    (rw,wdelay,root_squash,all_squash,no_subtree_check,anonuid=500,anongid=502)

五、在nfs client上操作：

[root@test179 ~]# mkdir -p /u02/nfsdata
[root@test179 ~]# ls -ld /u02/nfsdata
drwxr-xr-x 2 root root 4096 Aug 17 07:27 /u02/nfsdata

[root@test179 ~]# cat /etc/fstab
