oracle 23ai（23.5.0.24.07）完整功能版安装体验

发表于 2024 年 7 月 26 日 由 惜分飞

最近oracle 发布了for exadata、oda以及云端的oracle 23ai版本,今天在x86环境中进行了安装测试,安装环境非常顺利,基本上按照安装需求配置好,然后一路下一步(注意选择不创建库)即可
ORA23AI-install

dbca创建库会遭遇到ORA-27350
ora-27350
由于我这是普通的x86环境,需要设置_exadata_feature_on参数来骗过数据库,参考:ORA-12754: Feature ‘startup’ is disabled due to missing capability ‘Runtime Environment’
最终效果

根据官方描述这个问题（Bug 21452473 – Windows: INS-30131 while Installing 12.1.0.2 Database/Client on Windows (Doc ID 21452473.8)）是由于c盘没有被共享的原因,解决方案:
1)启用c盘共享；2)使用ignorePrereq 参数跳过检测

Symptoms:
 While performing 12.1.0.2 Database or Client installations on windows install will fail with following error:
 
 [INS-30131] Initial setup required for the execution of installer validations failed and unable to proceed 
 
 At the command prompt net use will return the following error :
 
  net use \\hostname\c$ 
  ^
  System error 53 has occurred
  The network path was not found. 
 
Cause :
 The error is caused due to Administrative share disabled . If they cannot be enabled perform the following workaround.
 
Workaround :
 For client software  installations, run the installer with following args:
 
 setup.exe -ignorePrereq -J"-Doracle.install.client.validate.clientSupportedOSCheck=false" 
 
 For Database Installation, run the installer with following args:
 
 setup.exe -ignorePrereq -J"-Doracle.install.db.validate.supportedOSCheck=false"
