Using unix host command within plsql on aix

On an aix platform Im trying to host out of a plsql procedure to
use mail. I can only get the host command to work inside a blank
.sql file. ie. first line must have the host command on it. If
you try to imbed the host command within a procedure, the file
will just sit there and nothing happens.

Run like Host command in plsql

Hi,
We are using Host command in sql*plus , but i need to implement like host command in Plsql. I refered previous post and some other links , that most of them are prefered only java stored procedure, And even that restricted previllage.
Can you give some sample example launchiing Win OS command in plsql
venki

To run a batch file, you need to use the Command Shell (and please do not call it a DOS shell like some people tend to do as it is not DOS). E.g.
c:\windows\system32\cmd.exe /c c:\temp\test.bat
We're running cmd.exe with switch /c that tells cmd to execute the command we're passing it, and then to terminate.
Note that we cannot interact with the shell from the PL/SQL side - we cannot answer prompts and so on. The script run, must be a proper batch/non-interactive script.
Also, the Oracle Server process (Win32 thread actually) that is servicing our Oracle client connection, is running the command for us. This thread itself is a background service process. It could run in Windows configured environment (VM/Virtual Machine) that is not allowed to interact with the desktop - or have limited or no access to certain files, folders and programs.
Technically speaking, this is what happens:
1) we pass the command to execute from our client to the Oracle server session servicing us
2) this Oracle thread uses the Java VM to make a Win32 call called CreateProcess()
3) the Win32 kernel executes that process
4) the process starts, runs and terminates
5) the Java VM inside the Oracle Server process regains control and pass the exit code and standard output of that process to PL/SQL
6) PL/SQL in turns, returns that very same data to our client
If you for example run a program that pauses and expects input, or hangs.. it will cause the above series of steps to stop at step 4. With the Java VM waiting on it to complete, and we waiting for the Java VM and PL/SQL call to complete.

Using the Host command

Hi,
I'm running windows 2000 O/S on my desktop to connect to an IBM AIX server to run Forms6. If you call the host command from within forms, does it go to the my desktop (client) or to AIX (server). Also, if I need a username and password to log onto AIX will I be prompted to for the username and password by the OS after issuing the host command? Please provide example if you can.
Thanks,
Leonard905

When you execute a HOST command the code is executed on the machine on which your Forms engine is running.
In client server this will be the client.
In Web deployed Forms this will be the middle tier application server.

Using unix 'diff' command to publish iweb to non .mac server

It is a common problem that you can't upload incremental changes to a website a web server that is not a .mac. Recently I found that the unix (shell) 'diff -qr' works nicely for this.
However I can't seem to get this to work in automator. That is where I need some help.
What I did :
I have an iweb website in my directory
Documents/website
I made a second directory where I store my uploaded version of the website:
Documents/websiteonserver
Using a shell script I want to compare the differences between these two directories using the diff command in a shell script. When I run 'diff -qr websiteonserver website' in a terminal window, it gives a nice overview of which files are changed and which ones are new. When workin with iWeb this saves me a lot of time uploading my homepage to a non .mac server. I can only upload the changed files, which is usually only a few. Diff does not look at timestamps (which are useless in the iweb case) but it actually looks into a file and with the -q option it stops when it finds a difference. With the -r added (-qr) it also looks through all subdirectories and compares files with the same name.
I like to automate this process so that my wife can update our family homepage with just one mouseclick (or as few as possible)
Unfortunately the diff command in automator gives an error, and there's no info on why it does this.
The commands I gave:
cd Documents
diff -qr websiteonserver website
(using PWD i verified that the path is correct like this). The only stumbling block for automator seems to be the diff command. Anybody any suggestions on this?
The next challenge is to take the diff output and use that to upload only changed/new files to a ftp server.
Any help / ideas are welcome
Greetings,
Adriaan

Dear Cyclosaurus,
I used a single command as us specified. It really helped to add the path to the directories I wanted to compare. So now at least I got it two work partly:
It seems to work only if I compare two files. Comparing directories still does not work. Maybe diff generates some kind of error code when doing this??? It does not do that in the shell.
If I compare all files in directories + subdirectories , the workflow does not work. It seems as if it only accepts a single output line or so from the diff function. If there is more output (or maybe some newline character) the workflow halts. Very peculiar.
mmm.... I will try to make a shell script which I can run in automator. In the script file I will then generate a txt file. Then the automator can run the script and then it can open the resulting file in a text editor. See if that works.
mmm nope. I made a script like this:
#!/bin/bash
diff -qr ~/Documents/websiteon_theserver/ ~/Documents/website/ > ~/Documents/logfile.txt
I modified the atributes to executable and I could run it from the command line. The logfile.txt was created and has the correct info. I could not run it from automator...
I did copy the last line from the script into automator. And also there it does create the logfile, but the automator still says there was an error and stops.
maybe I should try Applescript, were it not that I am totally clueless on that language...

Accessing tape device from Terminal program using UNIX tar command

I am trying to create some tape backups of very large files (.dmg images) using the UNIX tar command.
I have a 72GB HP 4mm DAT USB drive, which shows up in the system profiler as:
DAT72 USB Tape:
Version: 30.30
Bus Power (mA): 500
Speed: Up to 480 Mb/sec
Manufacturer: Hewlett Packard
Product ID: 0x0125
Serial Number: 4855310528334645
Vendor ID: 0x03f0
But I do not see the device in the /dev/ directory (see below).
Is there a way I can determine the UNIX device name?
Or must I locate and load a driver for this DAT drive?
Thank you
Jeff Cameron

I downloaded the BRU LE 30 day evaluation, and my first impression is favorable. I still need to perform a bit of testing. The HP drive I have does 36 GB per tape (72 at 50% hardware compression). My first attempt was to back up a single 22 GB .dmg file. Even with no compression it should have fit on one DAT tape, but after backing up 90% of the 22 GB it asked for a second tape. I still have to do more testing, but I very much appreciate the point in the very promising direction.
I will reply again to this thread with my results.

Opening a file using Webutil_Host.Host Command

Dear Gurus
I'm trying to open a file using following command behind a button on my form:
Webutil_Host.Host('x:\03\03\39920000023.gif');
I expected from this command to open the given gif file in default image viewer but it takes no action when I press the push button. So should I try something else???

try this

What's use of HOST command

Urgent please
In PL/SQL how can I call notepad ?? is the command HOST useful here ? If yes, how ?
Regards

We can use a java stored procedure to run OS commands. This is the most common use of java in the database. You can find the estimable Mr Kyte's implementation at AskTom.
I assume Notepad is just a random example, because PL/SQL is not interactive and I would guess that you won't actually be able to do anything useful by calling notepad from the database. Although if you do manage to do something useful let us know!

Expdb using Unix pipe command for max compression

I think the answer to this is NO, but I thought I'd ask the questions anyway, in case some of the Oracle geniuses on this site have figured out a way around this.
We have been using the existing exp/imp commands for years, due to the fact that we can pipe the output through a pre-setup file that will compress the data as it is written. Since we have moved onto the 10g and now the v11 software, we are starting to what to utilize the parallelism that is afforded in expdp, but don't want to deal with the space required for non-fully compressed exports that occurs with expdp.
So the question is, has anyone figured out a way to use expdp and using 'on the fly' compression like you could do with the old exp utility on Unix boxes??
Any help would be appreciated....

Unfortunately, no--it has to do with the parallel nature of the file ops that prevents compression through a pipe. However, if you buy the Compression option in 11--you can compress on the fly.
See this white paper.

How to run Unix Host commands from Database Triggers?

Hi
I need to create few directories in the Unix O/s under a specific directory (From a Database Trigger). And the directory names will be determined in the DB Trigger based on the data.
I hope someone would have come across a requirement like this and will be able to help me out.
Thanks.

Hi Christopher
How is it possible to use System calls from Triggers. Is it possible to use Runtime Libraries in DB Triggers.
Thanks

Running an SQR using HOST command

We are using Forms 10g and want to call sqr using the host command. The only way we can get this to work is to put the sqr call in a shell script which also contains all of the necessary environment variables and then use host to run that shell script.
I've tried putting the environment variables in default.env to no avail.
(This is a UNIX environment).
Is it possible to run an sqr directly using the host command?
host('sqr .....')
Thanks in advance!

nope. You can use host command. And modify the shell script in such
a way that the results are written to a text file and read the result using
text io
Best regards

How can I use unix commands from oracle report

Hi,
It's because .bat (or .cmd) files are scripts and not executables and are interpreted using the command line executable - which is normally cmd.exe (although you can buy others).
So you need to call cmd.exe passing the bat file name as a parameter, something like
cmd.exe /c batchfilename
Without the /c you will never get a response.
However, this brings us to the bizarre conclusion that you are going to:
call cmd.exe (a shell interpreter)
to launch a batch file
that calls cygwin (another shell interpreter)
which then runs ls
When shouldn't that just be:
call cmd.exe to run the dir command
Or better yet, If you are just after a file name listing and you seem to understand Java stored procs, why not just write a JSP to list the contents of a directory? No problems with OS dependant commands, scripts and 3rd party interpreters. Plenty of examples of that out on the internet as well.

How to run a HOST command from Report 2.5

Hello everybody,
I want to pass an unix command from a Report. I am running the report (Report 2.5) on an Unix server and I want to pass a unix host command inside the Before Report Trigger of the report. But Report2.5 is not recognising the HOST built-in. Is there is any way around?
Thank in advance.

First off is that openssl command correct? Should it be this instead:
openssl pkcs8 -inform der -nocrypt -in test.der -out result.pem
Try out your openssl command within a command prompt so that you know that it works ok. I think the command line you specified waits on stdin (well it does for me).
After that.....
runtime.exec creates a Process object. If you do this:
Process openssl = runtime.exec("....")
then you can examine the return code from openssl to see the exit code - for instance if the input file does not exist then exit = 1. You can test for this with Java
Alternatively you could get the stderr from the process and look inside it - if it is 0 length then all is good, if it has some text in there then it has likely failed. You could then throw an exception and include the stderr output in the exception messgae. You may need to experiment with this, runnig it first when openssl is happy then running it again when openssl is upset.

Host command in forms/reports

Is there a host command in reports 6i? I used this in forms 6i. When I tried to use in Reports 6i, I received a compile error.
basically all I need to do is to get directory information. This can be easily done in forms using the host command. Is there any built in package or function to achieve this in reports?
thanks

there is no "host" command in reports 6i (or earlier versions). you might want to consider using forms+reports combination (calling the report from within a form, in which you can execute the host command and do whatever you want to do, then pass the related parameters to the report). I am using this approach to handle some complex end user reporting requirements.
hope this proves useful
