Passing arguments to main method from a shell script
The main method of my class accept more than 10 arguments so my shell script execute this class like this :
java -cp xxxx mypackage.MyClass $*
The problem is that some of those arguments allows spaces. When i execute this script like this :
myscript.sh firstparam secondparam ...... tenthparm "eleventh param"
or
myscript.sh firstparam secondparam ...... tenthparm 'eleventh param'
the java class consider that my eleventh param is 'eleven' and not 'eleventh param'
The same class works well with an equivalent dos script.
I had this problem once also, and I found there are several ways to fix it. One way is to replace all of the spaces in the arguments with _ characters, or you can concantate all of the arguments into one String at runtime (with spaces in between) and use code to separate the arguments out. With the quotation marks, this code would be simple. If the spaces in one argument are used to divide different parts of the argument, just make them spearate arguments.

How to pass argument in main function ?
How to pass arguments in main function of one class from another class ?
I don't want to pass argument from command prompt.
I want to try something like this -
class Test{
public static void main(String args[]){
for(int i=0;i<args.length;i++)
System.out.println(args);
class Fun{
public static void main(String args[]){
Test t=new Test("Hello","good bye");
when i run Fun class it gives error.
Suggest me how can i do that.In Fun class main method does not take arguments that is fine. In Test class instead of main method you can have constructor to take input parameters as suggested by BalusC
However, if you want to make your existing code work, you can call (though not appropriate) main() method of Test class from main() method of Fun class (As main() method is static object is not required to invoke this):
Test.main(new String[]{"Hello","good bye"});Here is your code:
class Test{
public static void main(String args[]){
for(int i=0;i<args.length;i++)
System.out.println(args);
public class Fun{
public static void main(String args[]){
//Test t=new Test("Hello","good bye");
Test.main(new String[]{"Hello","good bye"});
} Thanks,

clas2.java:42: main(java.lang.String[]) in class1 cannot be applied to () c1.main();
any ideas on how to do this correctly
thanks in advance,
DonalHi thanks for the replies,
tried just passing a string earlier and that just gave errors too, I should have been more specific and pass a string array.
Its working now thanks again.

Passing Multiple Parameters to SQL Script from a Shell Script
Hi Friends,
I have SQL script which accepts 6 parameters.
I am calling this from a shell script as shown below:
sqlplus -s ${ORACLE_ID} @${SQLPATH}KORONT_041.sql ${USER_ID} ${PDC} ${item_number} ${KORDC} ${PDCSET} ${last_Updated_in_hours} Out of the six parameters, item_number is not a mandatory parameter.
When i pass all six parameters, there is no issue.
But when i leave item_number blank, i am getting the below error
Enter value for 6:
User requested Interrupt or EOF detected.Based on the error, it seems that the NULL values for item_number is ignored and SQL*PLUS is waiting for one more input from user.
How can i overcome this issue?
Regards,

Is it possible to pass a variable from a shell script back to an Automator action?
Is it possible to pass a variable from a shell script back to an Automator action?
For instance, if I assign a value of foo to $var1 in my shell script how would I retrieve/pass that value in the next Automator action. I see that there is a variable called "Shell Script" but I can't any information on how to use it.red_menace,
Thanks but I still don't understand how to pass a single value that was set in the UNIX scipt back to Automator has a variable. Take the example below, I write 4 varables to STDOUT and all 4 are stored in a variable named "storage". How do I assign 1 of these values to the Automator "storage" variable? For instance if I wanted to assign the value of $var2 to "storage" , how would I do that? -
Passing parameters to query called through a shell script
I have a file called getInfo.sql that contains a query like:
spool ./myInfo.txt
select *
from myTable
where col1 = '&val1'
and col2 = '&val2';
spool off
I would like to call SQLPLUS from a shell script and pass this file in as a parameter. How would I pass in the values for
&val1 and &val2 ?
Any help would be appreciated.
Thanks
RajanYes, you put a line in the script that looks like this:java classname parameter1 parameter2 parameter3 ...Then the JVM will call the static main(String[] args) method of "classname" and put those parameters into the "args" array.
If you are asking how to generate such a script, or how to call it from your COBOL program, sorry, I don't know how to do that. -
Debugging a program being called from a shell script
hi All,
i want to know how debug a C program being called from A Shell Script,
my script looks like the following :
ecReqProcMain $Cfg/ecReq.g $TotCnt 2>> $ErrFilei also have to pass some arguments to the script itsellft, which in trun going to pass it to the program,
also in some cases i may be required to Pipe some data to the program, like the folowing
cat DataFile | myProgramThanks ,You can also use ss_attach with the scheme that Anton
suggested above. Instead of inserting "dbx" into your
script, insert "ss_attach" into your script.
It's also possible to change your script to something like this:
cat DataFile | ${DEBUG} myProgram
Then you can run your script like this:
setenv DEBUG ss_attach
ecReqProcMain $Cfg/ecReq.g $TotCnt 2>> $ErrFile

Calling a report from unix shell script
Hi,
I had to call a report from unix shell script.
May i know the procedure to accomplish this
Thanks in Advance
A.GopalFirst you should not include the whole path to your report in the call ...
Use like this:
/ora/u01/oracle/v101/as2/bin/rwrun.sh report=an_stati destype=file desname=/ora/u01/oracle/v101/as2/test.pdf desformat=pdf
In $ORACLE_HOME/bin/reports.sh:
1) Verify that you have updated the REPORTS_PATH variable to include your folder where you have the report in question
REPORTS_PATH=/ora/u20/app/qits/env1/run:$ORACLE_HOME/reports/templates:$ORACLE_HOME/reports/samples/demo: ....
2) Verify that the REPORTS_TMP variable is pointing to a valid location and that the oracle user has access to write on it.
After that, post the content of the tracefile located at $ORACLE_HOME/reports/logs/{in-process report server name folder}/rwserver.trc
If no file is present then it means that you need to enable trace in your reports's conf file.... go to the $ORACLE_HOME/reports/conf folder and and locate the .conf file that correspond to your in-process reports server name (as specified in the rwservelet.properties file)... open/edit the file to enable trace logs ..
i.e.
Change the following line:
<!--trace traceOpts="trace_all"/-->
to <trace traceOpts="trace_all"/>
Bounce the reports server and try to run the report again, this time the .trc file should be generated, post the content so that we can take a look. -
Calling stored procedure from unix shell script
Hello,
I am facing a problem while calling a stored procedure from UNIX shell script. I want to return a output variable from the stored procedure to the UNIX environment.
Here is the code-
#!/bin/sh
OUTPUT=`sqlplus cmag/magnum@dw <<ENDOFSQL
set serveroutput on;
var prd_out varchar2(100);
exec create_pm_window(:prd_out);
exit;
ENDOFSQL`
echo " output is - $OUTPUT"
The problem is :prd_out is not getting copied to shell variable OUTPUT.
I have a dbms_output.put_line in the stored proc create_pm_window and I can see that prd_out is getting populated.
Any help is really appreciated.
Thanks'
RakheeFirst step :
make sure the PL/SQL works as expected.
Does the following display the expected output executed from SQL*Plus ?
set serverout on
declare
prd_out varchar2(100);
begin
create_pm_window(prd_out);
dbms_output.put_line('output is '||prd_out);
end;
I don't have your procedure, but using a dummy procedure like :
Scott@my10g SQL>create procedure foo(p_out in out varchar2)
2 is
3 begin
4 select 'Hello '||instance_name into p_out from v$instance;
5 end;
6 /
Procedure created. and a toto.sh script as :OUTPUT=`sqlplus -s scott/tiger <<EOF
set pages 0 lines 120 trimout on trimspool on tab off echo off verify off feed off serverout on
var mavar varchar2(100);
exec foo(:mavar);
print mavar;
exit;
EOF`
echo "OUT = ${OUTPUT}"
exitIt works fine :[oracle@Nicosa-oel ~]$ ./toto.sh

VinayHi Kamal and kanakam kolla,
This is just to let you know that,I solved my problem little differently by creating a new location and deployed the process flow.Now my process flow is working fine when i call from the shell script.What i see is that, it does not update properly when we update and redeploy the process flow.So far this is the work arround i could think off and i succesfully tested this.
Thank you Kamal and kanakam kolla,for giving a thought towards my problem.
Thanks

Return codes from sqlldr command from unix shell script

Eventhough, there are errors while executing sqlldr, it is always returing recode zero. What could be the possible reason
Please adviceIs there a typo in your code ?
sqlldr parfile=sdb.par control=$cntlfile data=$infile bad=$badFile log=$logFile rows=10000

Reading variables from a shell script
i was wondering if it is possible to enter variables from a shell script that an sql file can use:
ex:
shell script file
#!/bin/ksh
stty -echo
read pwd?"Enter password for user: "
echo
stty echo
read var?"Please enter value for variable: "
echo
$ORACLE_HOME/bin/sqlplus user/$pwd @TEST.sql
sql file TEST.sql
set serveroutput on
set verify off
spool out.log
update table set parameter_value = '$var' where parameter_name = 'X';
commit;
exit;
spool off;
i tried that and it seems its updating my table with "var" and not what the user entered that is the bind variable $var
am i missing something?if user hits enter (which means null) can the program
not end and ask the user to enter another value?Try this way :
while :
do
echo -n "Please enter value for variable: "
read VAR
if [ "$VAR" ]; then
break
else
continue
fi

Starting tomcat from a shell script

I want to start Tomcat from a shell script that is called by an application on a web page. Problem is, the app that calls the script runs as user nobody.

You don't want people to be able to start (or.. stop !) services on your server from a web page... That would present a gaping security hole.
