iSeries CL considerations

Besides the information in this topic collection, consider these topics when using iSeries™ CL commands to access VSAM data sets on a remote CICS^® system.

• ALCOBJ (Allocate Object)
  Unless the CICS system programmer replaces the CICS/DDM-supplied exclusive file lock program with a special version of the program, a lock condition value of *SHRRD or *SHRUPD must be used when using the Allocate Object (ALCOBJ) command to allocate a remote VSAM data set. All other lock condition values result in a server message on the iSeries server.
• CLRPFM (Clear Physical File Member)
  The Clear Physical File Member (CLRPFM) command cannot clear a VSAM data set on a remote CICS system.
• CPYF (Copy File)
  The Copy File (CPYF) command can access remote VSAM data sets defined to a CICS system.
• CPYTOTAP, CPYFRMTAP and CPYSPLF commands
  The Copy to Tape (CPYTOTAP), and the Copy from Tape (CPYFRMTAP) commands access remote VSAM data sets defined to a CICS system.
• DLCOBJ (Deallocate Object)
  The Deallocate Object (DLCOBJ) command can release any lock successfully acquired for a remote VSAM data set.
• DSPFD and DSPFFD commands
  The Display File Description (DSPFD) and Display File Field Description (DSPFFD) commands can display information about a remote VSAM data set.
• DSPPFM (Display Physical File Member)
  The Display Physical File Member (DSPPFM) command can be used to access remote relative record data set (RRDS). It does not work for other types of VSAM data sets.
• OPNDBF (Open Database File)
  The Open Database File (OPNDBF) command can open a remote VSAM data set.
• OVRDBF (Override with Database File)
  The Override with Database File (OVRDBF) command can override a local database file with a remote VSAM data set.
• RCVNETF (Receive Network File)
  The Receive Network File (RCVNETF) command can access a VSAM data set defined to a remote CICS system. However, the MBROPT parameter must have a value of *ADD.
