使用rman备份到挂载的NFS目录，提示ORA-19504-27054报错-优快云博客

本文链接：https://blog.youkuaiyun.com/zhrzhl/article/details/120796955

本文详细描述了在AIX 5.3环境中，如何解决Oracle 10g备份脚本因NFS挂载问题报错，以及如何修复expdp导出数据到NFS时的权限和配置错误。通过添加NFS配置、调整挂载选项和应用补丁，成功解决了数据备份和导出过程中的技术难题。

一、在AIX5.3下挂载NFS后，手动运行Oracle10g rman备份脚本

1、报错信息如下：

RMAN-03009: failure of backup command on ch1 channel at 05/08/2021 14:07:05

ORA-19504: failed to create file "/rmbackup/bak_20140505_7fp7hu6o_1_1"

ORA-27054: NFS file system where the file is created or resides is not mounted with correct options

NAS端检查共享目录，拥有读写及root权限，并且尝试在目录里面新建和删除文件操作，均未发现异常。

2、查询oracle相关论坛知悉可能是一个早期的bug，建议的操作如下

2.1、先在/etc/filesystems里面添加要挂在的nas共享目录信息条目

vi /etc/filesystems

#添加如下内容：

/rmbackup:

dev = /fs/gen3dbbackup/g3dbbackup

vfs = nfs

nodename = 192.192.5.159

mount = true

options = rw,bg,hard,rsize=32768,wsize=32768,vers=3,cio,intr,timeo=600,proto=tcp

account = false

2.2、再手动挂载nas共享目录，如下

mount -o hard,bg,proto=tcp,rsize=32768,wsize=32768,noac 192.192.5.159: /fs/gen3dbbackup/g3dbbackup /rmbackup

卸载目录注意事项：

直接使用umount /rmbackup，提示“umount: device is busy”，使用下面的命令进行卸载操作（Linux下通常是使用fuser -km /rmbackup 查询当前使用该目录的进程，并kill掉）

AIX下umount命令：

fuser -kxuc /rmbackup

umount /rmbackup #如果卸载但提示设备正被使用的话，可以使用umount -f参数

aix下启停nfs：

启动nfs

# startsrc -g nfs

关闭nfs

#stopsrc -g nfs

查看nfs

#lssrc -g nfs

2.3、备份脚本可以参考下面的

# cat oradb_bak.sh

rman nocatalog target / <<EOF

run{

configure retention policy to recovery window of 30 days;

CONFIGURE DEVICE TYPE DISK PARALLELISM 4;

allocate channel ch0 device type disk;

allocate channel ch1 device type disk;

allocate channel ch2 device type disk;

allocate channel ch3 device type disk;

crosscheck backup;

crosscheck archivelog all;

sql 'alter system archive log current';

backup database format '/rmbackup/FULLBAK_%T_%U';

sql 'alter system archive log current';

backup archivelog all format '/rmbackup/arch_bak_%T_%U' delete all input;

backup current controlfile format '/rmbackup/con_bak_%T_%U';

backup spfile format '/rmbackup/spfile_bak_%T_%U';

crosscheck backup;

crosscheck archivelog all;

delete noprompt expired backup;

delete noprompt obsolete;

delete noprompt backup of database completed before 'sysdate - 30';

release channel ch0;

release channel ch1;

release channel ch2;

release channel ch3;

}

exit

EOF

二、Aix5.3系统Oracle10g 使用expdp导出数据到NFS目录下报错处理

$ expdp backup/******** directory=exp_dir dumpfile=vhfs_full_%U.dmp logfile=vhfs_full.log full=y parallel=4

网络论坛博客上搜索了下资料，解决方法包括设置事件10298 level 32，alter system set event='10298 trace name context forever, level 32' scope = spfile;打补丁：5146667，或者在mount的时候设置参数：rw,bg,hard,nointr,rsize=32768,wsize=32768,tcp,vers=3,timeo=600,actimeo=0。

重新mount共享nas目录。

1、umount目录

umount /gen3

2、mount目录加一些参数

mount -o hard,bg,vers=3,proto=tcp,rsize=32768,wsize=32768,noac 192.192.5.159: /fs/gen3/gen3 /gen3

3、重新expdp导出文件到NFS目录
