The PRODUCT REGISTER PRODUCT command only updates the product database; it does not copy any files ' to your system. You can use this command to add information to the product database about products that have been installed by a mechanism other than PCSI, such as VMSINSTAL. You can also use this command to store information about products previously installed by the PCSI utility if the product database needs to be rebuilt due to file corruption or deleted database files. To register a product, you need to have a file in the source directory to supply details about the product being registered. This file can be one of the following: o A complete product kit o The product description file (PDF) extracted from the product kit or database o A special transition kit that identifies files installed by a mechanism other than the PCSI utility. If you do not have a kit available to provide detailed information about a product, you can use the command procedure SYS$UPDATE:PCSI$REGISTER_PRODUCT.COM to register the name of the product and its version, producer, and base system in the product database. After you register a product using the command procedure, other products can reference it, and the PRODUCT SHOW PRODUCT command displays it as an installed product.
