License keys for MFX and MFX’s value-added products can be maintained either in the SYNCMAC installation options macro or in a separate data set. To maintain the keys in SYNCMAC, use the SYNCMAC KEY option. To maintain the keys in a separate data set, specify the name of the data set in the KEYDSN option of SYNCMAC. Using a data set eliminates the need to assemble and link modules each time a key is added or replaced, and avoids SMP/E involvement. The data set option is recommended for sites that have many license keys and experience frequent key changes.
The data set can also be used to tell MFX to suppress key-related warning messages. As a license nears expiration, or if there has been a change to a machine on which MFX is executed, WER901I and WER903I messages may be issued. If you want to suppress these messages, you can do so by using a PARMS statement in the key data set.
For more information on the SYNCMAC options, see KEY-Related Options (KEY, KEYDSN, KEYMSG, and KEYWARN) in the guide itself. The remainder of this appendix deals with the key data set.
