9.12 To Show <strong>the</strong> Lock Statistic of an OM Using plockstat<br />
1. The syntax is: plockstat [ -o outfile ] -p pid. The program grabs a<br />
process and shows <strong>the</strong> lock statistics up<strong>on</strong> exit or interrupt.<br />
2. The following shows <strong>the</strong> lock statistics of an OM during <strong>on</strong>e of <strong>the</strong> 4600 user runs<br />
with large latch values and double ramp up time:<br />
$> plockstat -p 4027<br />
