GOAL:

When using Type 2 storage areas, do whole area clusters load into the buffer pool?

GOAL:

Do Type II storage areas cause entire clusters to load into memory?

GOAL:

Do single blocks load into memory when using Type 2 storage areas?

FACT(s) (Environment):

OpenEdge 10.x

FIX:

The database engine will only load the blocks containing the data and indexes required, not the entire cluster of blocks.

For example, if an area had a 512 cluster size and the following command was run:

FIND FIRST orderline NO-LOCK.

It would read into memory maybe 2 or 3 blocks (index & data blocks), not 1024 blocks (2 clusters).
