Resource definition for data tables
You define a data table in the same way as a CICS® file, except that you also need to specify the type of data table to be used, and the maximum number of records that can be held in the data table.
The VSAM KSDS definition supplies the maximum record length and the key length.
You can define a file as a data table by using the CEDA DEFINE FILE command, described in The DEFINE FILE command defines data tables.
Also, to change or check the data table attributes of an existing
file you can use:
- EXEC CICS SET FILE and INQUIRE FILE commands (see EXEC CICS commands for data tables)
- CEMT SET FILE and INQUIRE FILE commands (see CEMT commands for data tables)
