We are running several older applications using Rdb/VMS 4.1 under VMS 5.5-2. Up until now, we have not had to worry about the amount of disk space that the Rdb snapshot files were taking up. Now, this is no longer the case.

How do you trim the Rdb snapshot files back to their originally specified size? I already looked in the Rdb/VMS 4.1 Guide to Database Maintenance and several other Rdb/VMS 4.1 reference manuals and I could not find any information about how to perform this operation.

I would like to trim the snapshot files back to 100 blocks per file on a weekly basis, as part of the weekly full backup job.

Sincerely,
