關(guān)于達(dá)夢(mèng)數(shù)據(jù)庫(kù)一些疑難雜癥的解決

1.在用root用戶時(shí)開(kāi)啟了./manage 或 ./console 工具后，用其他用戶開(kāi)啟顯示No protocol specified
具體的報(bào)錯(cuò)：

問(wèn)題原因：用root用戶登錄后Display變量改變
解決辦法：將ROOT用戶下和普通用戶下的 Display變量值改成一致，并分別運(yùn)行 xhost+命令關(guān)閉用戶訪問(wèn)權(quán)限
ROOT用戶這里改成DISPLAY =: 0

普通用胡也改成DISPLAY =: 0
運(yùn)行xhost+


大功告成

2.安裝數(shù)據(jù)運(yùn)行命令時(shí)提醒No protocol Specified
其實(shí)這個(gè)問(wèn)題和第一個(gè)一樣

問(wèn)題原因：當(dāng)前操作系統(tǒng)的登錄用戶應(yīng)該為非dmdba用戶，如果在當(dāng)前會(huì)話中啟用圖形界面需要將圖形界面權(quán)限放開(kāi)。

[dmdba@localhost mnt]$

解決方法 切換到root用戶后在命令行中輸入xhost +，可以使得dmdba可以調(diào)用圖形界面進(jìn)行安裝。

利用DMRMAN備份時(shí)出現(xiàn)“管道連接失敗”的錯(cuò)誤信息現(xiàn)象描述備份時(shí)出現(xiàn) 故障“管道連接失敗”
問(wèn)題原因
遇到這種問(wèn)題時(shí)的場(chǎng)景，一般是安裝時(shí)在完成安裝之前沒(méi)有注冊(cè)dmap服務(wù)，這樣的情況下需要去注冊(cè)并啟動(dòng)dmap服務(wù)；也有可能是dmap服務(wù)被意外關(guān)閉，這種情況下啟動(dòng)dmap服務(wù)即可。

解決方法

1、重啟dmap服務(wù)

若沒(méi)有注冊(cè)dmap服務(wù)，有三種啟動(dòng)方式可供參考：

1.前臺(tái)啟動(dòng)dmap

前臺(tái)啟動(dòng)dmap，在安裝路徑下的bin目錄下，用./dmap即可啟動(dòng)dmap服務(wù)，但在前臺(tái)啟動(dòng)的方式下，關(guān)閉啟動(dòng)的當(dāng)前窗口，dmap即會(huì)被關(guān)閉。

2.后臺(tái)啟動(dòng)dmap

以這種方式啟動(dòng)dmap，在關(guān)閉當(dāng)前窗口后dmap服務(wù)不會(huì)被關(guān)閉。

3.通過(guò)腳本注冊(cè)dmap服務(wù)，用服務(wù)方式啟動(dòng)

利用腳本進(jìn)行dmap服務(wù)注冊(cè)并啟動(dòng)，在完整的軟件安裝過(guò)程中，在完成安裝前原本應(yīng)該以root身份運(yùn)行腳本來(lái)注冊(cè)啟動(dòng)dmap的。腳本在$DM_HOME/root目錄下。
