记录在linux 7中安装11.2.0.4 RAC遇到问题

发表于 2021 年 5 月 19 日由惜分飞

还有客户要求在linux 7平台中安装11.2.0.4的RAC,在这次的安装过程中,参考了Installation walk-through – Oracle Grid/RAC 11.2.0.4 on Oracle Linux 7 (Doc ID 1951613.1)文档,在安装grid的时候,执行root.sh执行,打上了patch 18370031,root.sh脚本非常顺利执行成功
打patch 18370031操作
一定要在gi安装执行root.sh之前打该patch

不安装该patch的,手动在systemd中添加ohasd服务
在root.sh执行过程中，待/etc/init.d/目录下生成了init.ohasd 文件后执行systemctl start ohasd.service 启动ohasd服务即可。若没有/etc/init.d/init.ohasd文件 systemctl start ohasd.service 则会启动失败,如果没有及时启动ohasd服务,导致root.sh执行失败,可以在启动ohasd服务之后,重新执行root.sh

(1).创建一个空服务文件：/usr/lib/systemd/system/ohasd.service
touch /usr/lib/systemd/system/ohasd.service

(2).编辑文件ohasd.service添加如下内容
vi /usr/lib/systemd/system/ohasd.service
[Unit]
Description=Oracle High Availability Services
After=syslog.target
[Service]
ExecStart=/etc/init.d/init.ohasd run >/dev/null 2>&1 Type=simple
Restart=always
[Install]
WantedBy=multi-user.target

(3).添加和启动服务
systemctl daemon-reload
systemctl enable ohasd.service
systemctl start ohasd.service

安装db软件时无法发现节点

通过参考mos文档 Database runInstaller “Nodes Selection” Window Does Not Show Cluster Nodes (Doc ID 1327486.1),应该是在安装过程中inventory信息异常导致,采用一下方法解决

[grid@ptdb1 bin]$ pwd
/u01/app/11.2.0/grid/oui/bin
[grid@ptdb1 bin]$ ./runInstaller -silent -ignoreSysPrereqs -updateNodeList 
>ORACLE_HOME=$ORACLE_HOME LOCAL_NODE="ptdb1" CLUSTER_NODES="{ptdb1,ptdb2}" CRS=true

'UpdateNodeList' was successful.

INS-35423错误解决

通过查询mos发现Window: Prerequisite Error INS-35423 And Warnings When Installing RAC Database Software (Doc ID 2164220.1)文章,虽然该文章描述的是windows环境,根据经验,我这个情况类似,按照该方法处理后正常

./runInstaller -jreLoc /etc/alternatives/jre_1.8.0 ORACLE_HOSTNAME="ptdb1"

安装db遇到Error in invoking target ‘agent nmhs’ of makefile ‘
这个是一个特别常见的错误,如果不使用dbcontrol,该错误可以直接忽略,或者采用类似方法处理
对$ORACLE_HOME/sysman/lib/ins_emagent.mk文件中的$(MK_EMAGENT_NMECTL)修改为$(MK_EMAGENT_NMECTL) -lnnz11,然后重试

如果要使用db console,如果在数据库安装完成之后打上patch 19692824
参考mos文档Installation of Oracle 11.2.0.4 Database Software on OL7 fails with ‘Error in invoking target ‘agent nmhs’ of makefile ‘ & “undefined reference to symbol ‘B_DestroyKeyObject’” error (Doc ID 1965691.1)
