Hi All,
is it possible to find out the size of an array of structures ( without using 'sizeof' operator). The condition is we have the array of structure instant but we are not aware of the elements inside the structure.
Can someone help me out?
Thanks in advance. (18 Replies)

I'm brand new to AIX and I looked up how to print this file and it was working but now I'm not able to do it all of a sudden. the file name is rom1.txt so this is what i wrote in the command line and I know I'm in the right directory. In bold is what I seem to be messing up with.

dbd::gofer::transport::stream
DBD::Gofer::Transport::stream(3) User Contributed Perl Documentation DBD::Gofer::Transport::stream(3)NAME
DBD::Gofer::Transport::stream - DBD::Gofer transport for stdio streaming
SYNOPSIS
DBI->connect('dbi:Gofer:transport=stream;url=ssh:username@host.example.com;dsn=dbi:...',...)
or, enable by setting the DBI_AUTOPROXY environment variable:
export DBI_AUTOPROXY='dbi:Gofer:transport=stream;url=ssh:username@host.example.com'
DESCRIPTION
Without the "url=" parameter it launches a subprocess as
perl -MDBI::Gofer::Transport::stream -e run_stdio_hex
and feeds requests into it and reads responses from it. But that's not very useful.
With a "url=ssh:username@host.example.com" parameter it uses ssh to launch the subprocess on a remote system. That's much more useful!
It gives you secure remote access to DBI databases on any system you can login to. Using ssh also gives you optional compression and many
other features (see the ssh manual for how to configure that and many other options via ~/.ssh/config file).
The actual command invoked is something like:
ssh -xq ssh:username@host.example.com bash -c $setup $run
where $run is the command shown above, and $command is
. .bash_profile 2>/dev/null || . .bash_login 2>/dev/null || . .profile 2>/dev/null; exec "$@"
which is trying (in a limited and fairly unportable way) to setup the environment (PATH, PERL5LIB etc) as it would be if you had logged in
to that system.
The ""perl"" used in the command will default to the value of $^X when not using ssh. On most systems that's the full path to the perl
that's currently executing.
PERSISTENCE
Currently gofer stream connections persist (remain connected) after all database handles have been disconnected. This makes later
connections in the same process very fast.
Currently up to 5 different gofer stream connections (based on url) can persist. If more than 5 are in the cache when a new connection is
made then the cache is cleared before adding the new connection. Simple but effective.
TO DO
Document go_perl attribute
Automatically reconnect (within reason) if there's a transport error.
Decide on default for persistent connection - on or off? limits? ttl?
