oracle - 对于 db recovery 进程测试，无法使用 shell 脚本获取查询 o/p

Question

我将shell脚本编写为：

#!/bin/bash
#shell script for recovery testing
$ORACLE_HOME/bin/rman target/ <<EOF >rman.log
        shutdown immediate;
        startup mount;
        run
        {
                recover database;
        }
        sql 'alter database open read only';
exit;
EOF

$ORACLE_HOME/bin/sqlplus '/as sysdba' <<_EOF1_ >sql.log
        spool '/home/oracle/test1.log'
        select * from hr.employees;
        spool off;
exit;
_EOF1_

，但是无法从sql查询中获取spool输出，如何解决这个问题？

Answer 1

我不知道你的代码有什么问题。它应该工作。我测试了它：

$ sqlplus '/as sysdba' <<_EOF1_ >sql.log
        spool '/home/oracle/test1.log'
        select * from dual;
        spool off;
exit;
_EOF1_

输出

$ cat sql.log

SQL>         spool off;

有两种选择可以实现您的目标。您将两者合二为一。有什么理由吗？

选项1

$ sqlplus / as sysdba << EOF > /dev/null
spool test.out
select * from dual;
spool off
EOF

输出

$ cat test.out 
SQL> select * from dual;

D                                                                               
-                                                                               
X                                                                               

SQL> spool off

选项 2

$ sqlplus / as sysdba << EOF > test.out 
> select * from dual;
> EOF

输出

$ cat test.out
