运行shell脚本以root用户身份连接到Oracle时出错

Question

I have a shell script file(Oracle_UserData.sh) on my ubuntu VM (shows below),

#!/bin/bash
echo "login to oracle 11g as sys"
chmod -R 755 /u01/app/oracle/product/11.2.0/xe
/u01/app/oracle/product/11.2.0/xe/bin/sqlplus -S sys/password as sysdba <<EOF
        create user $USER identified by $PASSWORD;
        grant all privileges to $USER;
        exit;
EOF

and I have another script file that runs as root, which would trigger the previous script file to run. (It runs as root because I'm passing the script as part of the Amazon EC2 user data).

#!/bin/bash
export USER=root
export PASSWORD=password

cd "/home/ubuntu/"
sh Oracle_UserData.sh
output: {all: '| tee -a /var/log/cloud-init-output.log'}

I am trying to create a new db user by running the these scripts, but it failed. I'm not sure if it's because the root user cannot access the environment variable or some other issue? I got the error

Error 6 initializing SQL*Plus

I tried to make those environment variable as a local variable by exporting them (ORACLE_HOME, ORACLE_BASE, ORACLE_SID), and I got the error that

ORA-12547: TNS:lost contact

(If I just make this script as a local file, and run it locally as Ubuntu, it works fine. User can be created with no issue.)

Can anyone help?

I got the problem solved by following the link below, http://www.dadbm.com/how-to-fix-ora-12547-tns-lost-contact-when-try-to-connect-to-oracle/

cd $ORACLE_HOME/bin

ls -ltr oracle
-rwxr-xr-x    1 oracle   oinstall       136803483 Mar 16 20:32 oracle

chmod 6751 oracle

ls -ltr oracle
-rwsr-s--x    1 oracle   oinstall       136803483 Mar 16 20:32 oracle
