恢复
首先看参数:
C:\Users\XCL>C:\dmdbms\bin\dmrestore.exe help
格式: DMRESTORE KEYWORD=value 或 KEYWORD=(value1,value2,...,valueN)
例程: DMRESTORE INI_PATH=c:\dm7data\dameng\dm.ini FILE=c:\dm7data\backup\test.bak
必选参数: FILE
关键字 说明(默认)
--------------------------------------------------------------------------------
INI_PATH 服务器的ini文件路径
FILE 备份文件
MAPPED_FIL 当指定res_type为4时,输出备份文件的映射信息到该文件
TIME 恢复到的时间点
ARCHIVE_DIR 备份时的归档目录 格式 (dir1,dir2,dir3,...)
BACKUP_DIR 备份文件存放路径,用于搜索备份文件 格式 (dir1,dir2,dir3,...)
DATAFIL_PATH 恢复时指定文件路径 (id1,path1,id2,path2,id3,path3,...)
MIRROR_PATH 恢复时指定镜像文件路径 (id1,path1,id2,path2,id3,path3,...)
PARALLEL_DIR 并行映射文件所在的完整目录名
RES_TYPE 还原类型(0,1,2,3,4) 0:备份文件还原,1:备份文件显示,2:归档文件还原,3:单步增量还原,4:输出备份映射文件。
END_LSN 还原到指定的LSN
LOG 还原的日志输出文件
HELP 打印帮助信息
然后,发现要保留下面文件,然后运行恢复命令才能恢复出来,否则老是提示少文件,这个和Oracle之类还真不一样。
就是说能删的只有 BOOKSHOP.DBF DAMENG目录 trace目录 arch目录
这有啥用?
删得只剩下这些文件,少一个恢复时都会报错,文档没解释,真不解
