File Management Table

Mandatory Control Table

The file management table is a mandatory control table. One FMT is required for each VSAM data set used, regardless of the processing environment (batch or CICS).

Contents

The FMT includes the following information:

• The table name
• The VSAM data set type
• The CA IDMS/DB record name that corresponds to the VSAM record
• The CA IDMS/DB set name that will contain the CA IDMS/DB records

The FMT can also include key length, key position, relative-record number, record length, buffer size, and erase options.
