I have code that executes an external command, vis:
eval {
local $SIG{ALRM} = sub { die "alarm\n" };
alarm $TIMEOUT;
$text = `$pre_command$host $post_command` || ( $connectOk = 0 );
alarm 0;
$errStr = $^E;
};
The command hangs for a reason I don't understand (its a PsExec of opmnctl
@cluster status -app on a windows oracle server). Unfortunately, the block
above never exits.
Is there a way I can protect my routine from hanging system calls?
