Change the Maximum Number of Tblspaces
Change the Maximum Number of Tblspaces
The maximum number of active tblspaces permitted by OnLine is specified
as
TBLSPACES
 in the configuration file.
You can make this change while OnLine is in online mode but the change
does not take effect until you reinitialize shared memory (take OnLine offline
and then to quiescent or online mode).
The maximum number of tblspaces is 32,000. The minimum is 10 per user
process (
USERS
). This minimum also must be greater than the maximum
number of tables in any one database, including the system catalog tables,
plus 2. (This minimum is required to permit OnLine to execute a
DROP
DATABASE
 statement.)
Refer to
 for further information about this limit.
If you are logged in as user informix, you can make this change from within

use the command-line option.
