使用rman備份到掛載的NFS目錄,提示ORA-19504-27054報錯
一、在AIX下掛載NFS後,手動運行rman備份腳本
報錯信息如下:
RMAN-03009: failure of backup command on ch1 channel at 05/05/2014 19:07:05
ORA-19504: failed to create file "/sapbackup/orabak/rman_bak/bak_20140505_7fp7hu6o_1_1"
ORA-27054: NFS file system where the file is created or resides is not mounted with correct options
Additional information: 6
然後檢查目錄權限,發現有讀寫和可執行的權限,並且嘗試在目錄裏面新建和刪除文件操作,均未發現異常。
二、查詢oracle官方資料,說可能是一個早期的bug
如是根據官方給的提示進行操作:
vim /etc/filesystems
#添加如下內容:
/sapbackup/orabak:
dev = /volume1/sap_db
vfs = nfs
nodename = 10.203.20.67
mount = true
options = rw,bg,hard,rsize=32768,wsize=32768,vers=3,cio,intr,timeo=600,proto=tcp
account = false
官方參考資料:
mount -o hard,bg,proto=tcp,suid,rsize=32768,wsize=32768,noac 10.203.20.67:/volume1/sap_db /sapbackup/orabak
直接使用umount /sapbackup/orabak,提示“umount: device is busy”,如是使用下面的命令進行卸載操作(Linux下通常是使用fuser -km /mnt/cdrom 查詢當前使用的進程,並kill掉)
AIX下umount命令:
fuser -kxuc /sapbackup/orabak
umount /sapbackup/orabak #如果卸載但提示設備正被使用的話,可以使用umount -f參數
mount -v nfs -o rw,bg,hard,rsize=32768,wsize=32768,vers=3,cio,intr,timeo=600,proto=tcp 10.203.20.67:/volume1/sap_db /orabak
# startsrc -g nfs
# nfso -a | grep nfs_use_reserved_ports
# nfso -o nfs_use_reserved_ports=1
# mount -v nfs -o rw,bg,hard,rsize=32768,wsize=32768,vers=3,cio,intr,timeo=600,proto=tcp 10.203.20.67:/volume1/sap_db /orabak
# mount 10.203.10.157:/SAP /nfs
# df -g
三、嘗試使用下面的備份腳本:
# cat sapprd_bak.sh
rman nocatalog target / <<EOF
run{
configure retention policy to recovery window of 31 days;
allocate channel ch1 device type disk;
crosscheck backup;
crosscheck archivelog all;
sql 'alter system archive log current';
backup database format "/sapbackup/orabak/rman_bak/bak_%T_%U";
sql 'alter system archive log current';
backup archivelog all format '/sapbackup/orabak/rman_bak/arch_bak_%T_%U' delete all input;
backup current controlfile format '/sapbackup/orabak/rman_bak/con_bak_%T_%U';
crosscheck backup;
crosscheck archivelog all;
delete noprompt expired backup;
delete noprompt obsolete;
delete noprompt backup of database completed before 'sysdate - 31';
release channel ch1;
}
exit
EOF
測試備份成功!

方案二:
生產系統需要導出數據到一個NFS目錄下報錯
bash-3.00$ expdp \'/ as sysdba\' directory=bak_data_pump_dir schemas=epm_ha dumpfile=epm_ha.dmp logfile=epm_ha.log

網上搜索資料,解決方法包括設置事件10298 level 32,alter system set event='10298 trace name context forever, level 32' scope = spfile;打補丁:5146667,或者在mount的時候設置參數:rw,bg,hard,nointr,rsize=32768,wsize=32768,tcp,vers=3,timeo=600,actimeo=0。在solaris系統上tcp參數不可用。
由於是生產系統,盡量采用不停數據庫來解決,重新mount。
1 umount目錄
umount /epmhis
2 mount目錄加一些參數
mount -F nfs -o rw,hard,nointr,noac,vers=3,rsize=32768,wsize=32768 IP地址:/epmhis /20100521
3 重新expdp導出文件到NFS目錄
