FMN2SSDM
In particular, before you can use FM/Db2, you must specify the Db2® subsystems, or Db2® data sharing groups, which FM/Db2 will use. To do this you must provide FMN2SSDM macro statements in FMN2POPT. For information about specifying Db2® subsystems and Db2® data sharing groups, and FMN2SSDM, see Defining all Db2 systems that FM/Db2 will access in FMN2POPT (required).
You must code at least one FMN2SSDM macro entry in FMN2POPT. When there is only one entry it should specify SSID=DEFAULT (see the description of the SSID option). When there are multiple entries, the final FMN2SSDM macro entry must specify SSID=DEFAULT. If this entry is omitted an assembler error will occur.
