oracle 18c 安装报ora-12754问题的解决

目前oracle发布的18c,只能安装在云上,若是咱们安装在本身机器上,使用dbca建立实例时,会报ora-12754的错误,有办法解决没有呢?
答案是确定的,有两种办法,一是上oracle 云上拷贝libserver18.a文件来解决,二是,直接修改参数_exadata_feature_on=true,以后,也能够启动:

Instead of changing lib file one can get the database running as follows -
1. instead of creating database using dbca, use dbca to get the scripts.
2. there will be 3 init* files. Modify all of them just place _exadata_feature_on=true.
3. execute xxxx.sh script to run and build database.

后面应该很快应该就有本地的安装介质出来,我选择了后者来解决.

而后,开启防火墙,就能够访问了.

[root@desktop0 ~]# firewall-cmd --permanent --add-port=5501/tcp
success
[root@desktop0 ~]# firewall-cmd --permanent --add-port=1521/tcp
success
[root@desktop0 ~]# firewall-cmd --reload
success

以上测试在centos 7.4上经过.
