Process 1--Defining the New Areas

Follow any of the procedures below that apply to the database you are reorganizing.

Create new COPY area--If you are creating a new area, the area must be defined in both the old and new subschemas in order for CA IDMS/DB Reorg to execute the COPY statement. Therefore, in the existing (old) database you must allocate and format an area having the new name, using IDMSBCF. The area can be of minimum size (one page is sufficient). This formatting must be done before the OPTALLOC step.

Allocate and format COPY areas--Database areas which are being copied must be allocated and formatted in the new subschema with IDMSBCF, before initiating the STORE step of CA IDMS/DB Reorg. Here are two suggested alternate times to allocate and format these areas:

1. Before initiating any steps of CA IDMS/DB Reorg.
2. Immediately before the STORE step. Use STOPAFTER=UPDLINK.
