ORA-27054错误处理

2024-07-09 15:30:18   226人阅读

今天在虚拟机环境下做实验，在将rac环境修改为flashback on时，报出了ORA-27054错误，错误代码如下：

Errors in file /u01/app/oracle/admin/racdb/udump/racdb2_ora_25551.trc:
ORA-38701: Flashback database log 2 seq 1 thread 2: "/u01/flashback/RACDB/flashback/o1_mf_%u_.flb"
ORA-27054: NFS file system where the file is created or resides is not mounted with correct options

从错误描述可以看出，闪回目录是通过nfs文件系统来实现的，而系统挂载nfs时，采用了错误的参数选项，导致oracle报错。上网查资料，通过文档359515.1顺利解决问题。整理部分内容如下：

RAC  

In the table below

  • Binaries is the shared mount points where the Oracle Home and CRS_HOME is installed.
  • Datafiles includes Online Logs, Controlfile and Datafiles

* NFS mount option “forcedirectio” is required on Solaris platforms when mounting the OCR/CRS files when using Oracle 10.1.0.4 or 10.2.0.2 or later (Oracle unpublished bug 4466428) 
** AIX is only supported with NAS on AIX 5.3 TL04 and higher with Oracle 10.2.0.1 and later (NetApp) 
*** NAS devices are only supported with HPUX 11.23 or higher ONLY 

# These mount options are for Linux kernels 2.6 and above for older kernels please check Note 279393.1

Due to Unpublished bug 5856342, it is necessary to use the following init.ora parameter when using NAS
with all versions of RAC on Linux (x86 & X86-64 platforms) until 10.2.0.4. This bug is fixed and included in 10.2.0.4 patchset.

* actime=0 or noac can be used

参照上文，修改mount参数如下：

[root@node2 bdump]# cat /etc/rc.d/rc.local
#!/bin/sh
#
# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don't
# want to do the full Sys V style init stuff.

touch /var/lock/subsys/local

service iscsi restart
#start_udev

modprobe hangcheck-timer
mount -t nfs -o rw,bg,noac,hard,nointr,rsize=32768,wsize=32768,nolock,proto=tcp,actimeo=0,vers=3,timeo=600 192.168.2.31:/u01/flashback/ /u01/flashback/

问题成功解决！


另外，在网上查到资料，还可以使用如下方式解决

1：设置事件10298 level 32

alter system set event=‘10298 trace name context forever,level 32‘ scope=spfile;

重新启动数据库后生效.


2：打补丁:5146667

 我没有试验，有兴趣的朋友可以试试，
