RHEL 7.X 或CentOS 7 安装 11.2.0.4 RAC碰到的问题
随着Linux 7 版本的普及,但Oracle数据库主流版本仍是11gR2,11.2.0.4 是生产安装首选。由于11.2.0.4对Linux 7 的支持不很完美,在Linux 7 上安装会遇到几处问题,以此记录下来。

1.安装GI执行root.sh脚本时,ohasd 进程无法正常启动
ohasd failed to start
Failed to start the Clusterware. Last 20 lines of the alert log follow:
2018-04-19 09:54:30.897:
[client(19244)]CRS-2101:The OLR was formatted using version 3.
alert:
Oracle High Availability Service has timed out waiting for init.ohasd to be started.
因为Oracle Linux 7(和Redhat 7)使用systemd而不是initd来启动/重新启动进程,并将它们作为服务运行,所以当前的11.2.0.4和12.1.0.1的软件安装不会成功,因为ohasd进程没有正常启动。
解决方法一:
在root.sh执行之前先打上补丁:18370031。
解决方法二:手动在systemd中添加ohasd服务
(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
查看运行状态:
[root@rac1 system]# systemctl status ohasd.service
● ohasd.service - Oracle High Availability Services
Loaded: loaded (/usr/lib/systemd/system/ohasd.service; enabled; vendor preset: disabled)

Apr 19 14:10:19 bms-75c8 systemd[1]: Starting Oracle High Availability Services...
(4).重新执行root.sh脚本
注意: 为了避免其余节点遇到这种报错,可以在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。
2.安装database软件,在执行root.sh脚本的时候会报错:
Error in invoking target 'agent nmhs' of makefile '/u01/app/oracle/product/11.2.0/db_1/sysman/lib/ins_emagent.mk'
解决方法一: 选择 继续,然后打上补丁:19692824 解决方法二: 编辑文件 $ORACLE_HOME/sysman/lib/ins_emagent.mk
vi /u01/app/oracle/product/11.2.0/db_1/sysman/lib/ins_emagent.mk
找到 $(MK_EMAGENT_NMECTL) 这一行,在后面添加 -lnnz11 如下:
$(MK_EMAGENT_NMECTL) -lnnz11 然后点击retry 即可
报错信息

BEGIN failed--compilation aborted at /u01/app/11.2.0/grid/crs/install/rootcrs.pl line 305.
解决方法
根据提示信息Can't locate Env.pm 可以知道找不到这玩意了。所以cp一份过去
[root@rac2 ~]#cp -p /u01/app/11.2.0/grid/perl/lib/5.10.0/Env.pm /usr/lib64/perl5/vendor_perl/
就OK了!记录一下
