I'm trying to remsh to another server and then execute a for loop command there but I'm getting unexpected errors and would appreciate any suggestions.
Ideally what I want to do is this:
Now my understanding is that you can't use new lines for remsh logic so the code would have to look like this:
Unfortunately I get the following error:
So clearly I'm doing something wrong. I've tried chaning the placement of the semi colons but to no avail.
Help!
I'm would like to log in su - within a script an contuine to run the commands within the script. Every time I log in as su - I have to exit for the rest of the script to run! e.g.
#!/bin/ksh
su - oracle
ps -ef |grep som <--- doesn't excute command until I log out su

Hi,
In ksh how can I execute something like this:

I cannot pass the contrl J or enter in th above line which is required by the for loop.
Thanks... (1 Reply)
I have a space delimited file containing: hostname OracleSID connectstring
I want to loop through the file and execute remsh to check the database processes.

Boy I hope someone can answer this question. I've been beating my head against the wall all day trying to come up with a solution.
I have a carrot delimited file that looks like this:

Sorry for such a dreadful title, but I'm not sure how to be more descriptive. I'm hoping some of the more gurutastic out there can take a look at a solution I came up with to a problem, and advice if there are better ways to have gone about it.

event::rpc::loop
Event::RPC::Loop(3pm) User Contributed Perl Documentation Event::RPC::Loop(3pm)NAME
Event::RPC::Loop - Mainloop Abstraction layer for Event::RPC
SYNOPSIS
use Event::RPC::Server;
use Event::RPC::Loop::Glib;
my $server = Event::RPC::Server->new (
...
loop => Event::RPC::Loop::Glib->new(),
...
);
$server->start;
DESCRIPTION
This modules defines the interface of Event::RPC's mainloop abstraction layer. It's a virtual class all mainloop modules should inherit
from.
INTERFACE
The following methods need to be implemented:
$loop->enter ()
Enter resp. start a mainloop.
$loop->leave ()
Leave the mainloop, which was started with the enter() method.
$watcher = $loop->add_io_watcher ( %options )
Add an I/O watcher. Options are passed as a hash of key/value pairs. The following options are known:
fh The filehandle to be watched.
cb This callback is called, without any parameters, if an event occured on the filehandle above.
desc
A description of the watcher. Not necessarily implemented by all modules, so it may be ignored.
poll
Either 'r', if your program reads from the filehandle, or 'w' if it writes to it.
A watcher object is returned. What this exactly is depends on the implementation, so you can't do anything useful with it besides
passing it back to del_io_watcher().
$loop->del_io_watcher ( $watcher )
Deletes an I/O watcher which was added with $loop->add_io_watcher().
$timer = $loop->add_timer ( %options )
This sets a timer, a subroutine called after a specific timeout or on a regularly basis with a fixed time interval.
Options are passed as a hash of key/value pairs. The following options are known:
interval
A time interval in seconds, may be fractional.
after
Callback is called once after this amount of seconds, may be fractional.
cb The callback.
desc
A description of the timer. Not necessarily implemented by all modules, so it may be ignored.
A timer object is returned. What this exactly is depends on the implementation, so you can't do anything useful with it besides passing
it back to del_io_timer().
$loop->del_timer ( $timer )
Deletes a timer which was added with $loop->add_timer().
DIRECT USAGE IN YOUR SERVER
You may use the methods of Event::RPC::Loop by yourself if you like. This way your program keeps independent of the actual mainloop module
in use, if the simplified interface of Event::RPC::Loop is sufficient for you.
In your server program you access the actual mainloop object this way:
my $loop = Event::RPC::Server->instance->get_loop;
Naturally nothing speaks against making your program to work only with a specific mainloop implementation, if you need its features. In
that case you may use the corresponding API directly (e.g. of Event or Glib), no need to access it through Event::RPC::Loop.
