Linux/Unix shell脚本中调用或执行SQL，RMAN 等为自动化作业以及多次反复执行提供了极大的便利，因此通过Linux/Unix shell来完成Oracle的相关工作，也是DBA必不可少的技能之一。本文针对Linux/Unix shell脚本调用sql， rman 脚本给出了相关示例。
一、由shell脚本调用sql，rman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
oracle@SZDB:~> ./rman_bak.sh |
