Thanks for the suggestion with regards to using a global variable. I am not opposed to doing this. I hope that it doesn't get lost on the poor DBAs here who will have to maintain these scripts when I eventually have to move on.
I started working on a proof of concept and hit an unexpected snag using eval. My thought is that I would pass a handle (just a string really) to my database functions and build variables based on the handle. When I try to redirect stdout and stdin to some open file descriptors, I get an error.
eval exec ${TESTVAR_stdout}>&p <==== results in "t[13]: 3: not found"
The previous lines work fine, I am scratching my head on why TESTVAR_stdout isn't expanding properly.
What is more perplexing is If I manually execute the lines with numeric literals, it works. If I manually execute the lines using variable and no "eval", KSH indicates that I have running jobs for stdout and closes my session for stdin.
If I can get past this hurdle, I can implement the concept easily.
Hi,
I have written a daemon process, to perform certain operations in the background.
For this I have to close, the open file descriptors,
Does anybody know how to find out the number of open file descriptors ?
Thanks in Advance,

Hi All,
This thread is going to be a discussion basically bringing out more information from the experts on cron jobs and the associated file handles.
So, here is the question.
There is definitely a constant ' n ' as the maximum number of file handles alloted to a process ' p '.

What is the difference between a file descriptor and a semaphore?
My basic understanding is:
- a file descriptor is a small positive integer that the system uses instead of the file name to identify an open file or socket.
- a semaphore is a variable with a value that indicates the... (1 Reply)

Apache::Session::Oracle(3pm) User Contributed Perl Documentation Apache::Session::Oracle(3pm)NAME
Apache::Session::Oracle - An implementation of Apache::Session
SYNOPSIS
use Apache::Session::Oracle;
#if you want Apache::Session to open new DB handles:
tie %hash, 'Apache::Session::Oracle', $id, {
DataSource => 'dbi:Oracle:sessions',
UserName => $db_user,
Password => $db_pass,
Commit => 1
};
#or, if your handles are already opened:
tie %hash, 'Apache::Session::Oracle', $id, {
Handle => $dbh,
Commit => 1
};
DESCRIPTION
This module is an implementation of Apache::Session. It uses the Oracle backing store and no locking. See the example, and the
documentation for Apache::Session::Store::Oracle for more details.
USAGE
The special Apache::Session argument for this module is Commit. You MUST provide the Commit argument, which instructs this module to
either commit the transaction when it is finished, or to simply do nothing. This feature is provided so that this module will not have
adverse interactions with your local transaction policy, nor your local database handle caching policy. The argument is mandatory in order
to make you think about this problem.
This module also respects the LongReadLen argument, which specifies the maximum size of the session object. If not specified, the default
maximum is 8 KB.
AUTHOR
This module was written by Jeffrey William Baker <jwbaker@acm.org>.
