CA Dynam for VSE User Guide

Physical Files
Physical Files
The following physical files are supported by CA Dynam/FI:
• Disk (DTFSD and DTFDA)
• Tape (DTFMT)
• VSAM (ACB/RPL)
VSAM files may not be changed to disk or tape using FI. Disk or tape files,
however, may be changed to VSAM files by FI.
Restrictions on DTF Types
Special Considerations
DTFSD DTFs that specify the following:
• UPDATE=YES (which includes COBOL files opened as I/O) may not be
converted to tape files using CA Dynam/FI.
• BLKSIZE=MAX can only be used for fixed blocked records. When used with
other record formats, it causes all CA Dynam/FI functions to be
suppressed.
Supported DTFDA files are converted to DTFPH files and imperative macros are
converted to Physical IOCS channel program sequences.
Control characters for DTFCN (console) files (SYSLOG support) are always
removed.
Unsupported DTFs
The following DTF types are not supported by CA Dynam/FI:
• DTFCD DTFs that specify a device type of 2560 or 5425 are not supported
by CA Dynam/FI.
• ASCII tape DTFs are not supported.
• Spanned record format is not supported.
• Diskette DTFs (DTFDU) are not supported.
