AUTOIDMS automatically creates Master Files and Access Files for the CA-IDMS network and LRF records, based on information stored in the IDMS Integrated Data Dictionary and user selections.
AUTOIDMS requires disk space to write the new file descriptions (and parameter log file, if applicable) to the MVS data sets specified on the initial input screen or to the disk accessed as file mode A in VM. In addition, sufficient disk space must be available for temporary work files created. The amount of temporary space depends on the size of the subschema being described.
For MVS execution, the Master Files IDMSIDD and AUTOIDMS must be members in the sequence of data sets assigned to the DDNAME MASTER. The IDMSIDD Access File must be a member in the sequence of data sets assigned to the DDNAME FOCIDMS. The AUTOIDMS FOCEXEC must be a member in the sequence of data sets assigned to the DDNAME FOCEXEC. These members should be located in your site's production FOCUS libraries as a result of the data adapter installation process.
For VM/CMS execution, the files AUTOIDMS FOCEXEC, AUTOIDMS MASTER, IDMSIDD MASTER, and IDMSIDD FOCIDMS should all be on a mini-disk available to the user. This is usually the FOCUS production disk, as a result of the data adapter installation process.
Before you begin, you should decide which record-types are appropriate for your Master File. Consider which record should be the root segment and which record/set relationships will be included as descendants. A review of the Entity Relationship diagram for the subschema will assist in these decisions. Since you can create several Master Files in the same AUTOIDMS session, with only one pass through the IDMS dictionary, you may want to prepare several views of the subschema before proceeding.
