在RAC的安装配置过程中虽然是严格仔细按照文档来实施但还是出现不少问题现整理出来。
现象一
在节点一安装数据库的时候出现以下错误
[oraclerac1 dbs]$ sqlplus /nologSQL*Plus: Release 9.2.0.4.0 - Production on Thu Feb 23 14:09:08 2006Copyright (c) 1982, 2002, Oracle Corporation. All rights reserved.SQL connect / as sysdba
Connected to an idle instance.
SQL startup nomount pfile/home/oracle/9.2.0.4/dbs/init.ora
ORA-00444: background process LMD0 failed while starting
ORA-07446: sdnfy: bad value for parameter .
SQL exit
Disconnected
查找了错误原因
[oraclerac1 dbs]$ oerr ora 444
00444, 00000, background process %s failed while starting
// *Cause: Usually due to a bad (or non-existent) background process image.
// *Action: Get a good background process image.
竟然是LMD0进程有问题重新分析了一下参数文件没有发现有错误的地方于是怀疑在安装的过程中出现问题。 尝试在节点二创建数据库
[oraclerac2 dbs]$ sqlplus /nologSQL*Plus: Release 9.2.0.4.0 - Production on Thu Feb 23 14:20:32 2006Copyright (c) 1982, 2002, Oracle Corporation. All rights reserved.SQL connect / as sysdba
Connected to an idle instance.
SQL startup nomount pfile/home/oracle/9.2.0.4/dbs/init.ora
ORACLE instance started.Total System Global Area 319923400 bytes

使用一样的参数文件在节点二却是可以的这说明推断还是正确的。
现象二
从节点二创建数据库成功然后在节点一启动数据库
SQL startup mount pfile/home/oracle/9.2.0.4/dbs/init.ora
ORACLE instance started.Total System Global Area 319923400 bytes
Fixed Size 451784 bytes
Variable Size 201326592 bytes
Database Buffers 117440512 bytes
Redo Buffers 704512 bytes
ORA-00439: feature not enabled: Real Application Clusters
以上错误我平台是RH AS3.2DB是企业版的9204所以不会是版本出现问题。在节点一安装的过程中发现 $ srvconfig -init 这个命令不能使用应该是某些组件还没有安装好删除后重装保留共享磁盘上节点一的REDO和UNDO数据文件然后直接在节点一进行startup mount pfile/home/oracle/9.2.0.4/dbs/init.ora这下成功了。
小插曲在节点一MOUNT的过程中还出现报控制文件出错的很纳闷节点二和节点一用的是同样的参数文件后来发现是参数文件中控制文件部分有换行的错误重新整理后错误就解决了。
现象三 监听的配置
监听的配置耗了一个上午的时间折腾按照文档去配置就是不行。。其间有时候监听可以起来但是建了TEST用户执行sqlplus test/testrac 报错
[oraclerac2 admin]$ sqlplus test/testrac2SQL*Plus: Release 9.2.0.4.0 - Production on Fri Feb 24 14:09:13 2006Copyright (c) 1982, 2002, Oracle Corporation. All rights reserved.ERROR:
ORA-12514: TNS:listener could not resolve SERVICE_NAME given in connect
descriptor
说明监听还是配置不正确监听配置的成功必须辅以tnsping rac 这个命令成功执行为准下面是最后我两个节点的配置参数

在监听配置的过程中还出现这样一个现象发现在节点二上无论怎么配置都出现以下故障
[oraclerac2 admin]$ lsnrctl startLSNRCTL for Linux: Version 9.2.0.4.0 - Production on 24-FEB-2006 14:40:20Copyright (c) 1991, 2002, Oracle Corporation. All rights reserved.Starting /home/oracle/9.2.0.4/bin/tnslsnr: please wait...TNSLSNR for Linux: Version 9.2.0.4.0 - Production

起初以为是端口的问题更改了监听的端口监听是成功了。但是后来想想两台不同的机器怎么会可能存在地址占用呢于是又去搜索故障原因检查配置文件最后 netstat -lpn发现有个1521的端口一直开着却什么事情也不干于是强制把这个进程给KILL掉再重新配置成功
