How to call a shell script from a java code

Hello can any one suggest me how to call a shell script from a java program that takes three parameters.
i have a shell script (msp_restore_gui) when i run this script in the command line in a RHEL5 ,SUSE10 and Debian machine it works fine .I even tested to call it from a java program and it also worked fine but when i used the same in a J2ee application where the user when clicks the restore button in a webserver this inturn sends the request to a java file named BackupManager.java where i call the shell script.But here it fails.Waiting for your suggestions.If you want i can put the code also here

yes the script is in /usr/local/mss/tools/backup and the script (msp_restore_gui) is as follows
#!/bin/sh

Shell script for executing java program

i want to write a shell script which will export the classpath and compile & run the java program.
any references from where i can get that?

Try typing "man sh" at the command prompt.
Ultimately it'll end up looking a lot like this:
#!/bin/sh
CLASSPATH=/path/to/a.jar:/path/to/anther.jar
JAVA_HOME=/path/to/where/you/installed/java
$JAVA_HOME/bin/java your.classes.package.YourClass

How do I set proxy settings for a Java app behind a corporate server?

I have the source code of a Download Manager program written in Java. It has to be run within my college network in which we use the "Corporate Client" server to access the internet. The HTTP proxy is 172.16.68.6 and Port number is 3128. How do I define these parameters in my java program so that it can download files from the internet?
The source code for the program is:
There are four classes:
1. DownloadManager.java
2. Download.java
3. DownloadTable.java
4. ProgressRenderer.java

Thank you for the quick reply! But the solution provided by you, it seems, has still not been able to address my issue. I ran the program at command prompt with your said parameters, but the download still gave an error in the App window.
Also, is there some way of defining these parameters in the source code? I am keen in using NetBeans to run the program.
Cheers!

Running UNIX shell scripts from a Java app

I want to build a GUI in Java as a front-end to a collection of UNIX shell scripts I have written. Is this possible?

It is possible, but it kinda defeats the purpose of shell scripts no?

Shell script for below pl/sql script dbms_file_transfer

Please let me know how tt write the shell script for below pl/sql script dbms_file_transfer it is

end;What database version?
What are you trying to do exactly?
It's working but you have to put it in a loop. Fine, what's the problem you are having?
begin
loop
    exit when ... whatever the exit condition is ...
    dbms_file_transfer.copy_file(
      source_directory_object => 'src',
      source_file_name => 'ncsn',
      destination_directory_object => 'dest',
      destination_file_name => 'ncsn');
end loop;
end;

Hi all,
I have migrated database from 8i to 10gr2.For Backup in 8i, we used a RMAN shell script (scheduled uding cron tab) to backup the database to Tape.(VERITAS BACKUP).
I am new to 10G.I checked out the options to backup the database using Oracle Enterprise manager DB console.
http://www.oracle.com/technology/obe/10gr2_db_single/ha/rman/rman_otn.htm#t1d
I am planning to take a test backup using the steps mentioned inthe above url.Could any one suggest whcih is the best option for database backup,eiether to use Oracle Enterprise manager DB console or thru RMAN shell script for backup..?

I woudn't suggest you to work with EM if you want to be a professional DBA. Start learning RMAN and use CLI instead of GUI

How to do multiple shell scripts in AppleScript

I got some solutions from previous posts on how to run sudo in Applescript, but there is still some minor syntax issues when I try to get to the destination directory. Usually in shell script I just type
cd directory-destination
in several lines to batch process those commands, but when I work with applescript, if I do do shell script for every "cd" command, instead of getting an overall result, I would get intermediate results individually.
I read doc and learned that there might be a way to put commands together by using the & sign?
Message was edited by: ttback

An individual do shell script command runs in its own shell, so to perform multiple commands within that shell you need to combine them into a single statement. You can use the ampersand '&' operator to concatenate text strings, and the semicolon ';' to separate the commands, for example:set theFolder to "/Applications"
do shell script "cd " & theFolder & "; ls -l ."See the technical note do shell script in AppleScript.

How to call a shell script via ODI

Hi,
I need suggestion on following issues:
1) How to call a shell script via ODI?.. I tried using OSCommand utility .inspite of the execution being successful the data is not written into the new file in the desired format. After processing new file is created in the mentioned location but its empty.
2) I'm calling a procedure in ODI to load data into my fact. But once the fact gets loaded i want to update the log details (num of rows processed,num of rows inserted,num of rows rejected etc) in my log table. I'm planning to use a proc for updating but need to know from where can i find these details. Is there a table in work rep which gives me these info like how we get if we execute an interface.?
Please help me out.. Its urgent
Regards
Surabhi

Hello,
Question 1 appears a little vague, please elaborate. If you're looking to capture a return value from the command execution, you will need to pipe the return value to a file, then read from there.
The execution information is stored in the SNP_STEP_LOG table in the Work Repository. You will need to do a series of joins to retrieve the exact table that was updated. Good luck with this...

Shell script for export backup in oracle 11g

Hi,
Oracle version 11.2.0..
O/S-AIX
How to write shell script for export full backup in oracle 11g and also need to remove 2 days of old backup.
Regards,
Raju

How to write shell script for export full backup in oracle 11g
Do you mean that export is your backup strategy ? is your database running in noarchivelog mode ? if so, then why ? if not so, then why not RMAN ?
need to remove 2 days of old backup.
If that mean remove files older than 2 days, you can use something like this :
$ find <absolute directory path> -mtime +2 -exec rm {} \;

Shell script for DB

Hi,
I have written shell script for below scenarios, can you please guide me to write this as correct way, requirment is,
1. i need to connect the database which is on unix server , but before connecting the DB some of the files needs to be removed from \tmp directory.
2. once removed the script need to connect the database and call the sql file which is in \tmp directory.
3. the output files will be stored in \tmp directory start with DB name.
4. finally csv files needs to be transferred to local windows with help of FTP. please find below the script
#!/bin/sh
rm -f /tmp/dbmon/DB1*
CONNSTRING=username/PASSWORD@service
sqlplus -s $CONNSTRING @/tmp/STATS.sql << EOF
EXIT;
EOF
HOST='xxxxx'
USER='xxxxx'
PASSWD='xxxxxx'
FILE='E:\STATS\DB1.*'
cd /tmp/dbmon
ftp -n -v $HOST << EOT
user $USER $PASSWD
prompt
mput $FILE
bye
EOT
EXIT;
EOF
Thanks

Hi ASP
It's always a good idea to write entries to timestamped log file without which you will never know where the script went wrong or failed.
This is not tested but just a small example
#!/bin/sh
export LOG_DIR=/tmp/log
export LOGFILE=$LOG_DIR/`basename $0`_${TIMESTAMP}.log
if [ ! -d $LOG_DIR ]
then
mkdir $LOG_DIR
fi
echo "Removing the temporary files from /tmp/dbmon at `date +%Y%m%d_%H:%M:%S`" | tee -a $LOG_FILE
rm -f /tmp/dbmon/DB1*
CONNSTRING=username/PASSWORD@service
echo "Run SQLPlus file" | tee -a $LOG_FILE
sqlplus -s $CONNSTRING @/tmp/STATS.sql << EOF
EXIT;
EOF
echo "Now FTP the files to windows box " | tee -a $LOG_FILE
HOST='xxxxx'
USER='xxxxx'
PASSWD='xxxxxx'
cd /tmp/dbmon
ftp -vn $HOST <<EOF
quote USER $USER
quote PASS $PASSWD
ascii
cd E:\STATS
mput DB1.*
bye
EOF

Shell Script for Startup and Shutdown the database

Hi,
i want Shell Script for Startup and Shutdown the database in Solaries.
could any one can hep me where i can get this script. or send to me to [email protected]
Thanks & Regards,

SHUTDOWN
SHUTDOWN ABORT]
Shuts down a currently running Oracle instance, optionally closing and dismounting a database.
Terms
Refer to the following list for a description of each term or clause:
ABORT
Proceeds with the fastest possible shutdown of the database without waiting for calls to complete or users to disconnect.
Uncommitted transactions are not rolled back. Client SQL statements currently being processed are terminated. All users currently connected to the database are implicitly disconnected and the next database startup will require instance recovery.
You must use this option if a background process terminates abnormally.
IMMEDIATE
Does not wait for current calls to complete or users to disconnect from the database.
Further connects are prohibited. The database is closed and dismounted. The instance is shutdown and no instance recovery is required on the next database startup.
NORMAL
NORMAL is the default option which waits for users to disconnect from the database.
Further connects are prohibited. The database is closed and dismounted. The instance is shutdown and no instance recovery is required on the next database startup.
TRANSACTIONAL [LOCAL]
Performs a planned shutdown of an instance while allowing active transactions to complete first. It prevents clients from losing work without requiring all users to log off.
No client can start a new transaction on this instance. Attempting to start a new transaction results in disconnection. After completion of all transactions, any client still connected to the instance is disconnected. Now the instance shuts down just as it would if a SHUTDOWN IMMEDIATE statement was submitted. The next startup of the database will not require any instance recovery procedures.
The LOCAL mode specifies a transactional shutdown on the local instance only, so that it only waits on local transactions to complete, not all transactions. This is useful, for example, for scheduled outage maintenance.
Usage
SHUTDOWN with no arguments is equivalent to SHUTDOWN NORMAL.
You must be connected to a database as SYSOPER, or SYSDBA. You cannot connect via a multi-threaded server. For more information about connecting to a database, see the CONNECT command earlier in this chapter.

reefish

Ree,
1. Find SSH client for windows, then execute SSH with Runtime.exec() on local host with arguments like remote host, auth, command to execute etc.
2. Get SSH client in Java and execute SSH commands on remote host using pure Java API.
Don't ask me for links, Google works today, I checked this
