@ @-109, 109, 109, 10, 10, 10, 10, 10, 10, 10.

Iftest "$#"-eq0

Then

Nohup$ledir/mysqld--basedir=$MY_BASEDIR_VERSION--datadir=$DATADIR

-skip-locking > > $err_log2 > & 1

+-- skip-locking-Omax_connections=1000 > > $err_log2 > & 1

Else

Nohup$ledir/mysqld--basedir=$MY_BASEDIR_VERSION--datadir=$DATADIR
