Changing a buffer pool

Select the cache icon, then select File | Properties.
Select the Buffer Pool tab.
In the list box, select the buffer pool that you want to change.
Click the Change button. The Add/Change Memory Pool dialog box opens. You can change the size of the pool or the wash size.
To change the size of the pool, edit the number in the Amount In Pool text box.
To change the wash size, change the number in the Wash Size box. The wash area is a portion of each memory pool used to ensure that queries that need clean pages in a data cache can find them. When the number of dirty pages (pages that have been changed in cache) fills the rest of the buffers and begins to enter the wash area, Adaptive Server writes the data in the wash area to disk. When this write completes, the wash area is marked clean and is available for queries needing clean pages.

The minimum wash size is 10 times the I/O size for the pool. For example in a 4K pool, the minimum size is 40KB. The maximum wash size is 80% of the pool size.
Click OK.
