RMAN是Oracle数据库备份管理中必须用到的管理工具。它的操作方式有很多种，我整理了一些常用的操作命令，汇总起来，以方便工作。
1 、备份数据库操作命令
简洁版
backup database plus archivelog format '/backup/rman/xx_%U.%T';
正规版
run {
allocate channel t1 type disk;
backup database format '/backup/rman/xx_%U.%T';
backup archivelog all delete input format '/backup/rman/xx_%U.%T';
sql 'alter system archive log current';
backup current controlfile format '/backup/rman/xx_%U.%T';
release channel t1;
}
加强版
run
{
delete noprompt obsolete;
allocate channel ch01 type disk rate 40M;
backup database filesperset 3 format '/backup/servdb_rman/db_%U.%T';
sql 'alter system archive log current';
backup archivelog like '+%' filesperset 20 format '/backup/servdb_rman/archivelog_%U.%T';
delete noprompt archivelog until time 'sysdate -1';
backup current controlfile format '/backup/servdb_rman/ctl_%U.%T' ;
release channel ch01;
}
