pmerge.exe runs automatically to merge pre-existing product tables with any<br />
new product tables distributed with the latest <strong>TT</strong> <strong>Gateway</strong> software.<br />
The only time you must use pMerge manually is if <strong>TT</strong> distributes updated product<br />
information in a customer advisory. <strong>TT</strong> distributes this product information in a file<br />
named <strong>CME</strong>.pmg.<br />
Note: If you run pmerge.exe as part of receiving an updated <strong>CME</strong>.pmg from a Customer<br />
Advisory, <strong>TT</strong> recommends running it during non-trading hours; the Price Server has to be<br />
stopped and restarted in order to see the new product table changes.<br />
You can run pMerge in two different ways:<br />
• From Window Explorer<br />
• From the Command Window<br />
