Synopsis
[Startup] DBSizesAllowed=n[n,n...]
n can be 8192, 16384, 32768, or 65536. The default value is 8192.
Description
DBSizesAllowed lists the database block sizes (in bytes) that you can select when creating a database.
For more information about creating and managing databases, see Configuring Databases.
Examples
DBSizesAllowed=8192,16384
DBSizesAllowed=8192,65536
Changing This Parameter
On the Startup page of the Management Portal (System Administration > Configuration > Additional Settings > Startup), in the DBSizesAllowed row, select Edit. Select each desired database block size. You cannot clear 8192.
When you enable an additional database block size, you must allocate memory for that block size using the globals parameter. This allows InterSystems IRIS® data platform to create the needed pool of global buffers for that size.
Instead of using the Management Portal, you can change DBSizesAllowed in the Config.StartupOpens in a new tab class (as described in the class reference) or by editing the CPF in a text editor (as described in Editing the Active CPF file).
