因工作需要，informix的數據庫是初次接觸
且工作單位使用的版本比較老，現於2019年於官網下載的最早版本爲iif.12.10.FC9DE
現記錄一下關於informix的安裝，命令操作，以及信息解讀
安裝使用的是開頭提到的12版
操作的系統是win10
在win10 的安裝過程中，涉及的密碼都統一輸入
採用默認安裝模式
未新建單獨的informix用戶
數據庫服務啓動需要使用管理員權限打開 ol_informix1210
（C:\Windows\System32\cmd.exe /k "C:\Aprograms\Bsystem\informix12\ol_informix1210.cmd"）
如果使用普通用戶從cmd打開，會提示
Message 71578 not found.
這是因爲沒有運行指定的cmd文件（缺少環境變量設置）
如果使用普通用戶打開-ol_informix1210-，會提示
Only members of IXDBSA group (Informix-Admin, by default) can start IBM
Informix Dynamic Server.
使用管理員啓動 ol_informix1210

提示實例正在運行
輸入 onmode -ky 停止服務
C:\WINDOWS\system32>onmode -ky
<EOM>
在停止服務情況下，分別輸入 onstat -p 或者 onstat -l 或者 onstat -d 三個查詢狀態的語句
C:\WINDOWS\system32>onstat -d
shared memory not initialized for INFORMIXSERVER 'ol_informix1210'
而輸入 onstat -m 則會在最後提示服務狀態
C:\WINDOWS\system32>onstat -m
