I have a problem with a bash script on an Ubuntu system. I need to program a script which connects to oracle an spool some queries to text files.
Almost all of this tasks are acomplished but the script doesn't run as it should be.
To generate the connection to oracle I use the following lines inside my script:
su oracle
export ORACLE_SID=DB_SID
export ORACLE_HOME=[ORACLE_PATH]
export TWO_TASK=[HOSTNAME:PORT]
export PATH=$ORACLE_HOME/bin:$PATH
sqlplus -s usr/pass << EOF
In the subsequent lines I make all the spooling of the data and finally for exiting from sqlplus I use the following lines:
quit;
To diconnect from sqlplus
exit
To exit from the su oracle session
EOF
And after the EOF tag I put some other commands to be executed.
Problem is when I run my script:
user# sh MyScript.sh
Instead of doing all the tasks, the script only executes the lines to the point of the << EOF and returns to me the control of the terminal still logged as the oracle user.
oracle#user#
If I type 'exit' and press enter then the rest of the script is executed.
I need the script to execute from start to finish without this middle step but I don't know how.
Thanks in advance.
In the end it's not neccesary to use the [su oracle] to make the export of the environment variables so I simply deleted the line:
su oracle
And the process worked like a charm.
Thanks for all who helped.

I've tried to create a bash script for connecting to my Oracle 19C database using sqlplus, I added the following code (which works also) :
#! /bin/sh.
connectsqlplus(){
sqlplus "'"sys/mypassword as sysdba"'"
EOF
}
connectsqlplus
The main problem is that I want to use this bash script to start the database, what I've created seems to only let me open the sqlplus terminal, I just want to add the SQL> startup so that the database starts but I'm not really sure how to add this command in the SQL terminal by using bash scripting.
Any help would be much appreciated ! Thank you .
#start_oracle_db.sh
ORACLE_SID=nameofyourdatabaseasrecordedinoratabfile
ORAENV_ASK=NO
source oraenv
sqlplus << EOF
connect / as sysdba
startup
exit
EOF
I have a script lying into a Unix server which looks like this:
mainScript.sh
#some stuff here
emailScript.sh $PARAM_1 $PARAM_2
#some other stuff here
As you can see, mainScript.sh is calling another script called emailScript.sh.
The emailScript.sh is supposed to perform a query via sqlplus, then parse the results and return them via email if any.
The interesting part of the code in emailScript.sh is this:
DB_SERVER=$1
USERNAME=$2
PASSWORD=$3
EVENT_DATE=$4
LIST_AUTHORIZED_USERS=$5
ENVID=$6
INTERESTED_PARTY=$7
RAW_LIST=$(echo "select distinct M_OS_USER from MX_USER_CONNECTION_DBF where M_EVENT_DATE >= to_date('$EVENT_DATE','DD-MM-YYYY') and M_OS_USER is not null and M_OS_USER not in $LIST_AUTHORIZED_USERS;" | sqlplus -s $USERNAME/$PASSWORD#$DB_SERVER)
As you can see, all I do is just creating the variable RAW_LIST executing a query with sqlplus.
The problem is the following:
If I call the script mainScript.sh via command line (PuTTy / KiTTy), the sqlplus command works fine and returns something.
If I call the script mainScript.sh via an external job (a ssh connection opened on the server via a Jenkins job), the sqlplus returns nothing and takes 0 seconds, meaning it doesn't even try to execute itself.
In order to debug, I've printed all the variables, the query itself in order to check if something wasn't properly set: everything is correctly set.
It really seems that the command sqlplus is not recognized, or something like this.
Would you please have any idea on how I can debug this? Where should I look the issue?
You need to consider few things here. While you are running the script, from which directory location you are executing the script? And while you are executing the script from your external application from which directory location it is executing the script. Better use full path to the script like /path/to/the/script/script.sh or use cd /path/to/the/script/ command to go to the script directory first and execute the script. Also check execute permission for your application. You as an user might have permission to execute the script or sql command but your application does not have that permission. Check the user id for your application and add that into the proper group.
I am trying to connect to an Oracle db using a ksh script. When I run this directly from the prompt, it works. But when I put it inside a script (abc.sh) it fails. Below is what I've put in the script (edited to make it shorter):
Here abc is the username, while abc$123 is the password of the user which has access on database DBNAME.
#!/usr/bin/ksh
sqlplus -s /nolog << EOF > output
connect abc/abc$123#DBNAME;
set echo off
set heading off
select table_name from dba_tables;
exit;
EOF
This works if typed directly, but run as ./abc.sh, gives error -
ERROR ORA-01017: invalid username/password; logon denied
I'm sure I'm missing something simple, but can't figure this out. Thanks for your help.
You cannot just write code like this and expect it to be passed to the relevant program. Your SQL lines are being executed by KSH instead of your SQL server. Instead you need to do something more along the lines of:
echo "SQL CODE HERE" | sqlplus ....
i have a problem with sqlplus on windows batch.
I have SQLPLUS 10.2
i'm trying to connect to a database through a windows script.cmd
script.cmd only launches : sqlplus test/Test#mydatabase #script.sql
The problem is when the database is not available, the sqlplus says
ERROR:
ORA-12541: TNS:no listener
Enter user-name :
and waits for input .. and blocks the .cmd
How can i adapt the script to stop immediately when the database is not avaliable or just to avoid waiting for user prompts ?
Thanks
You can do sqlplus -l test/Test#mydatabase #script.sql; the -l flag means it will only try to connect once, and if it fails for any reason will exit instead of prompting. Look at the output of sqlplus -?, or see the documentation.
may be you should think about using TNSPING utility. You can use it within CMD script before trying to connect to db with sqlplus. In this case you should analyse its output.
You can try with 2 connects.
First one will spool result to a file.
In the second one check what is in that file. If you don't encounter ORA-12541 or any other error messages then call the second script.
You can make all these commands inside one batch script and call it with
SQLPLUS #script.sql
and inside use
connect test/Test#mydatabase
I have a file to execute in Ksh written by someone. It has a set of commands to execute in sqlplus.
It starts with,
sqlplus -s $UP <<- END
followed by a set of ddl commands such as create,drop,etc.,
When I execute the file in the shell, I get the error in the starting line quoted above.
I understand "-s" starts the sqlplus in silent mode and $UP is the connection string with username/password. But I couldn't make heads or tails of "<<- END" part(Many sites from google says input redirection is "<<" not "<<-"). So I presumed the error must be in that part and removed it from the file.
Now it reads,
sqlplus -s $UP
But once I execute the file, It waits for input from the shell, instead of reading the rest of the lines from the file. How would I make sqlplus to execute the ddl commands in the rest of the file?. Thanks in advance.
Here "END" is a block marker and "-" is not required.
For running sqls from a shell script , One simple example is given below.
sqlplus system/manager << ENDOFSQL
whenever sqlerror exit sql.sqlcode;
select sysdate from dual;
exit;
ENDOFSQL
