IDMS VSAM database files on multiple volumes


Article ID: 186773


Updated On:


IDMS IDMS - Database


If a "normal" IDMS database area using EXCP is too large for one disk pack (volume), then the area must be mapped to multiple files.
With EXCP processing, IDMS database files cannot span multiple volumes.

Is the same true for files using VSAM as the underlying file access method (note this is NOT Native VSAM). 


Release : All supported releases.

Component : CA IDMS


An IDMS VSAM database file can span multiple volumes as long as it is less than 4GB in size, otherwise multiple files must be used.
See Placing Areas in Files.
