達夢數據庫常用操作命令
1.1 基礎操作
1.1.1 登陸dameng數據庫
我的服務部署在 /opt/dmdbms下面
cd /opt/dmdbms/bin
./disql SYSDBA/SYSDBA:5236 #登陸達夢數據庫
#如果密碼中有@符號，會登陸失敗，可以用下面這種方式登陸
#./disql 'SYSDBA/"K9uhb6qazMp1b@noah"'@localhost:5236
1.1.2 創建用戶
./disql SYSDBA/SYSDBA:5236
create user FSSC_V20_HW identified by "DEa_Q4r_rEW8+zwK7xp+0Dt+Y9uV_nZlFg3_TpAY" limit failed_login_attemps unlimited;
grant dba to FSSC_V20_HW;
2.1 導出達夢數據庫
./dexp CONSOLE_V20_HW/123456789@192.168.0.66:5236 FILE=dexp03.dmp LOG=dexp03.log DIRECTORY=/opt/ SCHEMAS=CONSOLE_V20_SJS
#CONSOLE_V20_HW/123456789 賬號密碼
#FILE 導出的dmp文件名稱
#LOG 導出日志的名稱
#DIRECTORY 導出到哪個目錄下
#SCHEMAS 指定導出哪個schema
eg2:
./dexp "FUSION_EAM_V20_HW"/'"123456789"'@LOCALHOST:5236 DIRECTORY=/home/dmdba/backup FILE=FUSION_EAM_V20_HW.dmp OWNER=FUSION_EAM_V20_HW TABLESPACE=Y DROP=N LOG=FUSION_EAM_V20_HW_exp.log LOG_WRITE=N
2.2 導入達夢數據庫
./dimp CONSOLE_V20_HW/123456789@192.168.0.66:5236 FILE=/opt/dexp03.dmp LOG=db_str1.log DIRECTORY=/opt/ remap_schema=CONSOLE_V20_SJS:CONSOLE_V20_HW
#remap_schema 跟oracle倒庫一樣，重命名schema，否則導入的schema是導出的schema名稱
eg2:
./dimp "FUSION_EAM_V20_HW"/'"DEa_Q4r_rEW8+zwK7xp+0Dt+Y9uV_nZlFg3_TpAY"'@LOCALHOST:32141 DIRECTORY=/home/dmdba/backup FILE=FUSION_EAM_V20_HW.dmp LOG=FUSION_EAM_V20_HW.log LOG_WRITE=N
