达梦数据库怎么写shell脚本，怎么通过shell脚本调用sql脚本

如题所述

通过shell脚本调用sql脚本：
1、shell脚本调用sql脚本
#首先编辑sql文件
oracle@SZDB:~> more dept.sql
connect scott/tiger
spool /tmp/dept.lst
set linesize 100 pagesize 80
select * from dept;
spool off;
exit;

#编辑shell脚本文件，在shell脚本内调用sql脚本
oracle@SZDB:~> more get_dept.sh
#!/bin/bash

# set environment variable

if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi

export ORACLE_SID=CNMMBO
sqlplus -S /nolog @/users/oracle/dept.sql #注意此处执行sql脚本的方法 -S 表示以静默方式执行
exit

#授予脚本执行权限
oracle@SZDB:~> chmod 775 get_dept.sh

-->执行shell脚本
oracle@SZDB:~> ./get_dept.sh

DEPTNO DNAME LOC
---------- -------------- -------------
10 ACCOUNTING NEW YORK
20 RESEARCH DALLAS
30 SALES CHICAGO
40 OPERATIONS BOSTON

2、shell脚本调用rman脚本
#首先编辑RMAN脚本
oracle@SZDB:~> more rman.rcv
RUN {
CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 7 DAYS;
CONFIGURE BACKUP OPTIMIZATION ON;
CONFIGURE CONTROLFILE AUTOBACKUP ON;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/users/oracle/bak/%d_%F';
ALLOCATE CHANNEL CH1 TYPE DISK MAXPIECESIZE=4G;
ALLOCATE CHANNEL CH2 TYPE DISK MAXPIECESIZE=4G;
SET LIMIT CHANNEL CH1 READRATE=10240;
SET LIMIT CHANNEL CH1 KBYTES=4096000;
SET LIMIT CHANNEL CH2 READRATE=10240;
SET LIMIT CHANNEL CH2 KBYTES=4096000;
CROSSCHECK ARCHIVELOG ALL;
DELETE NOPROMPT EXPIRED ARCHIVELOG ALL;
BACKUP
DATABASE FORMAT '/users/oracle/bak/%d_FULL__%U';
SQL 'ALTER SYSTEM ARCHIVE LOG CURRENT';
BACKUP ARCHIVELOG ALL FORMAT '/users/oracle/bak/%d_LF_%U' DELETE INPUT;
DELETE NOPROMPT OBSOLETE;
RELEASE CHANNEL CH1;
RELEASE CHANNEL CH2;
}

#编辑shell脚本文件，在shell脚本内调用rman脚本
oracle@SZDB:~> more rman_bak.sh
#!/bin/bash

# set environment variable

if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
export ORACLE_SID=CNMMBO
$ORACLE_HOME/bin/rman target / cmdfile=/users/oracle/rman.rcv log=/users/oracle/bak/rman.log
exit

#授予脚本执行权限
oracle@SZDB:~> chmod 775 rman_bak.sh
#执行shell脚本
