Issue with running multiple commands withing su command
RHEL 6.2/Bash shell

root user will be executing the below script. It switches to oracle user and expect to do the following things

A. Source the environment variables for BATGPRD Database (the file used for sourcing is shown below after the script)
B. Shutdown the DB from sqlplus -- The section between EOF takes care of this
C. execute ps command and grep for the string pmon
D. Execute srvctl start command to start the database

Commands for A,B,C and D and enclosed in a single quote delimited by colons.

Issue description:
DB is shutdown succesfully from sqlplus (A & B ). But ps command and srvctl commands shown in red are not executed.
The exit command shown below (in green below) is actually the exit from sqlplus. I don't if this affecting the execution of remaining
sections of the script.


Code:
# cat test1.sh
su - oracle -c 'source /home/oracle/BATGPRD1_oracle_env;sqlplus -s / as sysdba <<EOF
spool /home/oracle/SCRIPTS/Clone/mytestSQL.log
set echo off
set heading off

select sysdate from dual;
shutdown immediate;
select name, open_mode from v$database;
exit
EOF; ps -ef | grep pmon ; srvctl start database -d BATGPRD'
#
#

#
The file which I am sourcing above
Code:
# cat /home/oracle/BATGPRD1_oracle_env
export ORACLE_SID=BATGPRD1
export ORACLE_HOME=/db/product/oracle/11.2
export PATH=$PATH:$ORACLE_HOME/bin
#

#


### Script execution
Code:
# ./test1.sh
-bash: line 9: warning: here-document at line 0 delimited by end-of-file (wanted `EOF')

Database closed.
Database dismounted.
ORACLE instance shut down.
select name, open_mode from v

EOF needs to be on it's own, try this:
Code:
EOF
ps -ef | grep pmon ; srvctl start database -d BATGPRD'

You can do it like this:

Code:
su - oracle -c "source /home/oracle/BATGPRD1_oracle_env;sqlplus -s / as sysdba <<EOF ; ps -ef | grep pmon ; srvctl start database -d BATGPRD
spool /home/oracle/SCRIPTS/Clone/mytestSQL.log
set echo off
set heading off

select sysdate from dual;
shutdown immediate;
select name, open_mode from v$database;
exit
EOF
"

Can I suggest putting the code in another script (like /usr/local/bin/o_info) and pass $database in as a parameter you can the call with su like this:

Code:
su - oracle -c "/usr/local/bin/o_info $database"

Thank you Subbeh. Your fix worked.

Hi Chubler,
Your idea of passing DB name as a parameter is great. Hope it won't treat $database as a literal because of the double quotes. Let me try to modify the script as per suggestion. If it works, it will make my script much more flexible. Thank you ChublerXL

Regarding Chubler's example

Code:
su - oracle -c "/usr/local/bin/o_info $database"

Is double quotes used when you need to pass a parameter ?

-c is for command.. that means a string, so to pass more than 1 string you will use double quotes making what is within considered as a single...

Hi vbe,
As you can see above, OP used just single quotes to enclose multiple commands. So double quotes are not actually needed when you have multiple commands. Right ?
