Increases in Limits
Limits in TurboIMAGE/iX
Limits in TurboIMAGE/iX

Overview
Customers have often expressed the need for increased capacity for some of the elements
in TurboIMAGE/iX such as, number of items, number of datasets, number of paths,
capacities, etc. This article describes the limits in TurboIMAGE/iX that have been
increased.
The following sections describe which elements have increased limits and by how much.
Current Limitations
1. Number of items that the user can currently define in a database - 1023
2. Number of sets per database - 199
3. Number of paths for each master to detail - 16
New Limits
IMAGE and IMAGE/SQL have been enhanced so that the new limits for the above
elements are as follows:.
1. Number of items - 1200
2. Number of sets-240
Naming the datasets: Each database can contain up to 240 datasets. Each dataset is
referenced by a unique dataset name. If the root file name is XXXX, the first dataset
defined in schema will be XXXX01, the second dataset will be XXXX02, etc. up to
XXXXO0. As earlier, any of these datasets can be a Jumbo dataset and any of these
datasets can be expanded by using the capacity expansion in the schema, (if it is not
Jumbo).
3. Number of paths for master - 64
The number of paths per master has been extended from 16 to 64. Note that this is
only for master data sets.
Compatibility
Any new databases created will have the benefit of these increased limits. However the
new limits will not be applicable for databases created prior to this version of
TurboIMAGE/iX. Databases created prior to this will continue to function the same, as
there is full forward compatibility.
DBSCHEMA changes:
A database with any one of the above new limits will have the 'root version' as C5.
DBSchema has been enhanced to support the new limits.
