In storeBackupCheckBackup, a block begins with "unless ($parJobs)," and this blog figures out how many jobs to run in parallel. This code is Linux specific, and yields an uninitialized value error when run on OpenSolaris because there is no file /proc/cpuinfo for the program to examine. Instead, on Solaris, you need to run psrinfo -v. Here is a new version of the block that can work properly in Solaris, and will at least issue a warning if it doesn't recognize the OS.


unless ($parJobs)
{
    local *FILE;
    $os = $^O;
    if ($os =~ /linux/)
    {
        if (open(FILE, "/proc/cpuinfo"))
        {
            my $l;
            $parJobs = 1;
            while (<FILE>)
            {
                $parJobs++ if /processor/;
            }
            close(FILE);
            $parJobs *= 3;
        }
    }
    elsif ($os =~ /solaris/)
    {

        # Look for "virtual processor". This doesn't check if it is online or not.
        my $returncode = `psrinfo -v`;
        my @array = split/\n/.$returncode;
        $parJobs = 1;
        foreach (@array)
        {
            $parJobs++ if /virtual processor/;
        }
        $parJobs *= 3;
    }
    else
    {
        $prLog->print('-kind' => 'W',
              '-str' => ["Can't find # of processors in operating system $os"])
        $parJobs = 1;
    }
    $parJobs = 3 if $parJobs < 3;
}
