1.在线物理全备脚本

脚本里面的路径，用户密码需要根据实际情况调整,压缩一定要开启，并行度根据实际环境设置：
vi full_bak.sh

#!/bin/bash
cd /home/dmdba/dmdbms/bin/
./disql  SYSDBA/SYSDBA<<EOF
set serveroutput on
DECLARE
SQL_ VARCHAR;
begin
print sysdate;
SQL_='backup database  backupset ''/dmbak/DB_FULL_'||to_char(sysdate,'YYYY_MM_DD')||''' compressed level 1 parallel 4';
EXECUTE IMMEDIATE  SQL_;
print sql_;
print sysdate;
end;
/
exit;
EOF

2.物理增备脚本

vi increment_bak.sh

#!/bin/bash
cd /home/dmdba/dmdbms/bin/
./disql  SYSDBA/SYSDBA<<EOF
set serveroutput on
DECLARE
SQL_ VARCHAR;
begin
print sysdate;
SQL_='backup database INCREMENT WITH BACKUPDIR ''/dmbak'' backupset ''/dmbak/DB_INC_'||to_char(sysdate,'YYYY_MM_DD')||''' compressed level 1 parallel 4';
EXECUTE IMMEDIATE  SQL_;
print sql_;
print sysdate;
end;
/
exit;
EOF
