一. 故障描述

使用一个已经安装了AIX 6.1+HACMP+ORACLE RAC 10.2.0.5 环境创建备份,然后在一个新的POWER 5上使用这个备份进行操作系统全恢复.系统恢复后,ORACLE的环境已经有了,现在需要在这个环境下建立一个single db(单实例DB).

笔者尝试通过手工建立单实例DB的方法,启动数据库实例到nomount状态时,报错:

SQL> startup nomount;

ORA-29702: error occurred in Cluster Group Service operation

无法进行下面的数据库创建工作.

二. 故障分析

首先查看数据库警告日志文件,内容如下:

$ more alert_test1.log

数据库警告日志中涉及了/oracle/admin/test1/udump/test1_ora_2425116.trc,查看改trace文件,内容如下:

在metalink上搜索了ORA-29702,找到了一个非常有价值的文章,内容如下:

Starting Instance Fails with ORA-29702 [ID 216030.1]

修改时间 16-SEP-2010 类型 PROBLEM 状态 PUBLISHED

fact: Oracle Server Enterprise Edition 8

fact: Oracle Parallel Server (OPS)

fact: AIX-Based Systems

symptom: Starting database fails

symptom: ORA-29702: error occurred in Cluster Group Service operation

symptom: Mounting database in Non-OPS (exclusive) mode

symptom: Environment not configured for OPS

cause: Oracle in IBM RS6000 SP installs the Parallel Server Option as the

default option. As a result, Oracle tries to communicate with GMS or Cluster

Manager during startup, but the environment is not configured to work in

Parallel Server mode.

fix:

Relink Oracle to disable Parallel Server Option:

$ cd $ORACLE_HOME/rdbms/lib

$ make -f ins_rdbms.mk no_parropt

$ make -f ins_rdbms.mk install

这个文档说的情况与本问题的情况吻合,需要解决的问题就是取消并行模式(创建单节点DB,而非RAC DB).

三. 解决方法

执行metalink文档中的fix的命令，取消并行服务器模式。

$ cd $ORACLE_HOME/rdbms/lib

$ make -f ins_rdbms.mk no_parropt

rm -f /oracle/product/10.2.0/db/lib/libskgxp10.a

到此，问题得到解决，数据库可以启动到nomount状态，可以进行下面的手工创建数据库的操作了。
