我如何使用 python 子进程模块将 sqlplus 作为 sudo 连接到 oracle 用户？

Question

我有一个由 root 用户拥有的 python 脚本，我正在尝试运行 sqlplus 命令作为 sudo 到 oracle user.But 遇到 oracle_home not set 之类的问题

import os,subprocess
query = '''
WHENEVER SQLERROR EXIT FAILURE
SET FEEDBACK OFF
SET HEAD OFF
SET EMB ON PAGES 0 NEWP
SET LINE 10000
SELECT * from dual;
EXIT;
'''
dbsession = subprocess.Popen(["/usr/bin/sudo","-u","oracle","/orahome/Database/db12c/bin/sqlplus", "-S", "/ as sysdba"], stdin=subprocess.PIPE,stdout=subprocess.PIPE, stderr=subprocess.PIPE,env={"ORACLE_SID": "EMREP", "ORACLE_HOME": "/orahome/Database/db12c"})
dbsession.stdin.write(query)
query_result = dbsession.communicate()
print(query_result, dbsession.returncode

输出

(('', 'Error 6 initializing SQL*Plus\nSP2-0667: Message file sp1<lang>.msb not found\nSP2-0750: You may need to set ORACLE_HOME to your Oracle software directory\n'), 1)

dbsession.stdin.write(query)
query_result = dbsession.communicate()
print(query_result, dbsession.returncode)
