如何为sudo来oracle用户使用python子模块，我连接的sqlplus？

Question

我有root用户拥有的python脚本，我试图运行sqlplus的命令，sudo来甲骨文user.But越来越像ORACLE_HOME没有设置问题

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

output

(('', '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)

The below code worked

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;
'''
db_home=/orahome/Database/db12c
dbsession = subprocess.Popen(["/usr/bin/sudo","su","-","oracle","-c",""""""""+db_home+"""/bin/sqlplus -S / as sysdba"""""], stdin=subprocess.PIPE,stdout=subprocess.PIPE, stderr=subprocess.PIPE,env={"ORACLE_SID": "EMREP", "ORACLE_HOME": "+db_home+"})
dbsession.stdin.write(query)
query_result = dbsession.communicate()
print(query_result, dbsession.returncode)
