当前环境:

数据库备份在磁带中，备份软件EMC NETWORKER，备份server端和client端均为Solaris

先使用如下RMAN脚本恢复控制文件到/oracle/X01/nfsdata/目录下，该目录为nfs，当前mount没有使用任何参数，查看状态如下：

root@r3mok01 # mount |grep nfsdata

/oracle/X01/nfsdata on 10.8.5.218:/oracle/X01/datafile20140930 remote/read/write/setuid/devices/rstchown/xattr/dev=5f4000d on Tue Oct 28 16:24:58 2014

现在，执行RMAN脚本进行恢复

run

{ALLOCATE CHANNEL t1 DEVICE TYPE sbt_tape

PARMS='ENV=(NSR_SERVER=BKSRV01,NSR_GROUP=SAP_ECC,

NSR_CLIENT=r3prddb01,NSR_DATA_VOLUME_POOL=ECCPRD)';

RESTORE CONTROLFILE TO '/oracle/X01/nfsdata/cntrlP011.dbf.20140929'

FROM 'P011_beovwuge.273781_1' ;

release channel t1;

}

using target database control file instead of recovery catalog

allocated channel: t1

channel t1: SID=267 device type=SBT_TAPE

channel t1: NMO v4.5.0.0

Starting restore at 29-OCT-14

出现如下错误。

channel t1: restoring control file

released channel: t1

解决方法：

使用如下参数进行mount

mount -F nfs -o rw,hard,nointr,noac,vers=4,rsize=32768,wsize=32768 10.8.5.218:/oracle/X01/datafile20140930 /oracle/X01/nfsdata
