I have a requirement where i need to execute a unix shell script "a.sh" having permissions user1,group1 and no access to public. This should be executed from Oracle function.
So i wrote a routine in Java and it works fine when i execute a command like Date etc.
But when i execute "a.sh" from oracle client, its returning error that "could not be executed-permission denied". This is because once login happened through the "sqlplus" the shell takes user as "oracle" and group as "dba" but the script "a.sh" having only permissions user1,group1. Unfortunately we are not allowed to change the permission for "a.sh" to give execute permission to all(public).
After searching in internet, i understand that one way is to make the password (/etc/passwd) for the user "user1" as no password and can use "su" command so that it wont ask password while invoking it.
Is there any other way apart from this doing changes in password file at UNIX level when executing a script from oracle client?
if further information is required.
Oracle: version: 11.2.0.1
UNIX : AIX -5.9

An application uses one user as a container of objects(this user is stripped of ALL privileges), and other users that can access objects in this unique schema depending on their privileges.
There can be multiple installations of the application in one database, therefore many such schemes. An environment variable APP_UNIQUE_SCHEMA points to a current unique schema.
So instead of typing
select * from my_unique_schema.my_table I want to set a current schema for sqlplus session in glogin.sql.
It would have been nice if I could have entered in glogon.sql the following line
alter session set current_schema=$APP_UNIQUE_SCHEMA;
BUT it does not work. sqlplus does not resolve the reference to an environment variable. I cannot figure out how to get the value of an environment variable in sqlplus.

I am having issues passing variables to a separate sqlplus script invoked by the shell script, e.g.
#!/bin/sh
DB_NAME=TEST
PWD1=PA55W0rd
echo exit | sqlplus / as sysdba @${DB_NAME}.sql ${DB_NAME} $PWD1 >> ${DB_NAME}.sql
exit 0
The script picks up the $DB_NAME variable fine, and therefore invokes the required sql script. However, when I pass the variable $PWD1 to the sql script I get an error. The script creates a database link:
create or replace procedure new.link
is
begin
execute immediate 'create database link TEST
connect to TESTSCH identified by '$PWD1'
using ''TEST''';
end;
/
exec new.link;
/
output is:
ERROR at line 1: ORA-00911: invalid character ORA-06512: at "NEW.LINK", line 4 ORA-06512: at line 1

I am using Oracle 9i and Unix on my system and trying to execute a UNIX shell command through external procedure in C.I created a shared lib (libextproc.so) for the following function.
int sysrun(char *command)
{
return system(command);
}
This function runs fine when caled through a driver function in C, meaning that the shared lib is fine.In PL/SQL, I have used the following method to invoke a UNIX command:-
create or replace library shell_lib as '/home/ECETRAonsite/oracle/OraHome1/lib/libextproc.so';
/
create or replace function sysrun (syscomm in varchar2)
return binary_integer
as language C
name "sysrun"
library shell_lib
parameters(syscomm string);
/
Now when I call this PL/SQL function to invoke the command, it is run succesfully but does not create the file.
SQL>
1 declare
2 rc number;
3 begin
4 rc := sysrun('/bin/touch /home/ECETRAonsite/oracle/OraHome1/test/sach');
5 dbms_output.put_line('Return Code='||rc);
6* end;
SQL> /
Return Code=0
PL/SQL procedure successfully completed.I have verified that the path for 'touch' is correct.Following are my configuration files.

Which of the below is considered a bind variable. In example one proc. Test the parameter p1 is directly used in the query, so this can be considered as a bind variable.
Is that true about the second proc. where p1 is assigned to a local variable v1 , or this needs hard parsing because v1 is not a bind variable ?
Create or replace procedure test(p1 IN VARCHAR2,p_refcursor OUT SYS_REFCURSOR) IS
BEGIN
OPEN p_refcursor FOR select * from Test_tab WHERE item=p1;
END;
------------
Create or replace procedure test1(p1 IN VARCHAR2,p_refcursor OUT SYS_REFCURSOR) IS
v1 varchar2(100):=p1;
BEGIN
OPEN p_refcursor FOR select * from Test_tab WHERE item=v1;
END;

I've a requirement of running shell script in pl/sql procedure. I thought of doing this by using dbms_scheduler package. I believe while executing the jobs using dbms_scheduler the owner has to be part of DBA group, but as per my company policy (security issue) only DBA users has to be part of this group and i'm not able to . So is there anyway i can execute shell script in pl/sql procedure other than using dbms_scheduler.

I created a procedure with cursor to inquiry a table. There is more than 1 million records on the table. For each record, I would like to transfer two columns on table as parameter to shell and feedback to procedure as varcahr2.
This is my sample(I only use 10 records for the testing).
create or replace procedure task_file(task_check in varchar2,file_name out varchar2) is
k number :=0;
v_task_number number :=0;
v_task_filename varchar2(30) := null;
cursor jobchk is select task_number,task_filename into v_task_number,v_task_filename from my.tasktable
where task_filename=task_check and rownum <=10;

I have a procedure that checks in the table if the daily refresh was successful or not for the previous day. If it failed I would like to receive an email, which I accomplish with calling my EMAIL() procedure. Otherwise call my program_scheduler that will run a shell script.
Below is my procedure:
create or replace
PROCEDURE RD_ODS_REFRESH_LOG
IS
BEGIN
FOR i IN
(
SELECT RESULT FROM RD_REFRESH_LOG
[code].....
And here is CALL_SHELL job that my procedure calls:
BEGIN
SYS.dbms_scheduler.create_job (
job_name => 'CALL_SHELL',
job_type => 'EXECUTABLE',
job_action => '/home/oracle/load_semantic.sh',
[code].....
My ELSE statement never gets executed, why?

I have to write a script to do the following requirement. There is a file called BUSINESS_DATE.TXT. This file get updated once the oracle partition created. In Oracle, artition will be created every day. There is a seperate script scheduled to take care ORACLE partition creation. The above file will have only one row. i.e. 03092012
If Oracle partition creation job failed, the above file won't be updated. My requirement is, I have to check whether the BUSINESS_DATE file is updated today or not. If yes, I will have to move the files from common area to input file directory to process those files. All file name will amend with current date. i.e .
LIDDIFD03092012.TXT
The key part is to check the BUSINESS_DATE.TXT file is updated properly or not. We don't know what time the file will get updated. So we are planning to schedule the new script to run for every 15 mins to check whether the file is updated or not
But...I just thought instead of writing a shell script to do the above one, Why shouldn't I capture the date in a table (New table needs to be created) and use ORACLE TRIGGER to run the shell script to move the files from common area to input file directory to process those files?
My Proposal in ORACLE :
Create table business_date
(
rep_date varchar(15),
curr_timestamp timestamp
)
Once the oracle partition created , one row will be inserted into the above table. This adjustment needs to be implemented partition script. Once this table get record, TRIGGER should call SHELL SCRIPT to move the files from common area to input area.
If I implement ORACLE TRIGGER, The script which will check whether the file got updated or not for 15 mins is not required.

I am trying to call a shell script through external procedure. To summarize the steps that I followed:
Placed the library file,i.e., the .so file in bin folder of the database server. I have not compiled the .c file and created this. I have taken this from another application.
Then I logged into the sqlplus. Created one library pointing this .so file.
create or replace library ext_proc as '/ngs/app/ivndrptd/bin/execute_cmdlib.so';
After this created the external procedure. This got compiled without any errors.
SQL> create or replace procedure ext_proc_wrapper(in_script IN varchar2)
as external
library ext_proc
NAME "execute_cmd"
parameters (in_script string);
/
Procedure created.
I am trying to execute a script test.ksh which contains a touch command to create a test.txt file.
However irrespective of the procedure running successfully the script is not getting called. I tried several ways of calling the script which are as follows
SQL> exec ext_proc_wrapper('sh /ngs/app/ivndrptd/test.sh');
PL/SQL procedure successfully completed.
SQL>
SQL> exec ext_proc_wrapper('/ngs/app/ivndrptd/test.sh');
PL/SQL procedure successfully completed.
SQL>
SQL> exec ext_proc_wrapper('/ngs/app/ivndrptd/test.ksh');
PL/SQL procedure successfully completed.

I'm working on trying to write a shell script to parse a parameter file, but at the same time I want to be able to overwrite the parameter file settings with other command line settings. For instance if my par file had export/import settings for the username, password, schema, etc;
I wanted to run the same export/import with those settings for a different schema. I want to be able to put the schema=<different_than_par_file> after the parfile=<parfile.par and have the parfile be read and applied for everything except the different schema.
Right now I'm storing the cmd line and parsing it again looking for other parameters besides the parfile.
