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

 [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 :

 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"

配置win环境ssh和sftp并实现免密登录

发表于 2024 年 7 月 21 日 由 惜分飞

在某些情况下,需要在win环境中安装ssh,sftp等服务,可以考虑通过安装OpenSSH,下载地址:https://github.com/PowerShell/Win32-OpenSSH/releases,下载最新版OpenSSH-Win64.zip并解压
openssh安装服务

C:\Windows\system32>cd E:\OpenSSH-Win64

C:\Windows\system32>e:

E:\OpenSSH-Win64>powershell.exe -ExecutionPolicy Bypass -File install-sshd.ps1
  [*] E:\OpenSSH-Win64\moduli
Inheritance is removed from 'E:\OpenSSH-Win64\moduli'.
'NT AUTHORITY\Authenticated Users' now has Read access to 'E:\OpenSSH-Win64\moduli'.
'BUILTIN\Users' now has Read access to 'E:\OpenSSH-Win64\moduli'.
      Repaired permissions

  [*] C:\ProgramData\ssh
      looks good

[SC] SetServiceObjectSecurity 成功
[SC] ChangeServiceConfig2 成功
[SC] ChangeServiceConfig2 成功
sshd and ssh-agent services successfully installed
Updated Machine PATH to include OpenSSH directory, restart/re-login required to take effect globally

E:\OpenSSH-Win64>net start sshd
OpenSSH SSH Server 服务正在启动 ..
OpenSSH SSH Server 服务已经启动成功。

E:\OpenSSH-Win64>ssh -V
OpenSSH_for_Windows_9.5p1, LibreSSL 3.8.2

设置服务为自动启动
openssh

也可以可以通过cmd命令设置:sc config sshd start= auto

配置免密登录
1)修改C:\ProgramData\ssh\ssh_config文件

PubkeyAuthentication yes
AuthorizedKeysFile %programdata%/ssh/administrators_authorized_keys

2)拷贝C:\ProgramData\ssh\ssh_host_rsa_key为C:\ProgramData\ssh\administrators_authorized_keys
3)下载ssh_host_rsa_key和ssh_host_rsa_key.pub文件，放到其他机器的C:\Users\用户名\.ssh目录中并重命名为id_rsa和id_rsa.pub

测试其他机器免密ssh/sftp登录
