Batch Storage Requirements

CA IDMS Extractor batch storage requirements depend on the following factors:

• The size of the source and target subschemas.
• The size of the largest database record included in a database path.
• The sort storage requirements.
• Whether the components are run under a central version (CV) or in local mode.

The tables in the Batch Storage Requirements--EXTRACT Step and Batch Storage Requirements--LOAD Step sections show the amount of batch storage that is required for the Database Extract and Database Load Components, respectively, when executing the components under a CV. If the components are to run in local mode, additional storage is required for:

• CA IDMS runtime system modules
• Journal and database buffers.
