Customizing the FM/Db2 Primary Option Menu

This customization step is optional. Review this information to determine if you need to perform this step.

The FM/Db2 Primary Option Menu panel (FMN2ST00) provides an option to select Db2® Interactive. If the DB2I option is selected, the exec FMN2DB2I is called.

If you have customized the method used to start DB2I, for example, if your site displays a Db2® authorization panel before starting DB2I, you may need to modify the FMN2ST00 panel or the FMN2DB2I exec.

Owing to the wide range of possible customizations the information provided here is not specific to any particular method.

Panel FMN2ST00, as supplied, includes the following: 
&ZSEL = TRANS(TRUNC(&ZCMD,'.')
  0,'PANEL(&FMN2STSC)'
  1,'CMD(FMNDB2 D2B) MODE(FSCR)'
  2,'CMD(FMNDB2 D2E) MODE(FSCR)'
  3,'PANEL(FMN2STUT)'
  4,'PANEL(FMN2STSS)'
  5,'CMD(FMN2DB2I SSID(&FMN2SSIS)) MODE(FSCR)'    ◄ DB2I
  X,'EXIT'
  ' ',' '
DB2I indicates where FMN2DB2I is called when Option 5, DB2I, is selected.
The exec FMN2DB2I, as supplied, allocates a data set to DDNAME DSNETBLS, before invoking DB2I using the following ISPF SELECT statement: 
"SELECT CMD(DSNECPRI SSID("ssid")) NEWAPPL(DSNE) PASSLIB MODE(FSCR)"

You may need to customize either the panel FMN2ST00, or the exec FMN2DB2I, if your site has a customized exec or panels called prior to starting DB2I.

Note:
  1. FM/Db2 provides two methods for allocating the File Manager libraries. See Modifying the TSO logon procedure for further information. You must ensure that any processing in your site's Db2® invocation procedure does not de-allocate the FM/Db2 libraries.
  2. If your site's Db2® customization uses LIBDEF statements to allocate the required Db2® libraries, FM/Db2 allocates the required Db2® libraries (as defined in the FMN2SSDM macro for the connected Db2® system) at connect time: that is, when FM/Db2 is first started, or whenever the Db2® SSID is changed. FM/Db2 is connected to the Db2® system shown against "Db2® SSID" on the Primary Option Menu panel, FMN2ST00. This means that it is unnecessary for the DB2I invocation procedure to allocate the Db2® libraries prior to starting DB2I. You can determine the current LIBDEF allocation by starting FM/Db2 and issuing the ISPLIBD command on the command line.
  3. FMN2ST00 is distributed in FMN.SFMNPENU. FMN2DB2I is distributed in FMN.SFMNEXEC. If you decide to modify these or any other FM/Db2 parts to complete your customization for invoking DB2I, create a usermod to do this, to keep track of the changes to SMP/E controlled parts.
