5 8 System Partition Definitions

A system partition is a means of 'dividing up' or 'partitioning' one LANSA system. Each partition is completely separate from other partitions.

Points to note about partitions:

There is very little 'inter-partition' communication. Files, fields and processes defined in one partition are not directly accessible from another partition.

Each partition has a separate dictionary. Having too many partitions violates the concept of a corporate dictionary and increase maintenance.

Each partition has a separate security system. If you have too many partitions or too many users accessing multiple partitions this can become a maintenance problem.

Generally partitions should only be used to:

Separate large classes of users from one another (e.g.: production from development).

Generally partitions should NOT be used to:

Divide up applications or software packages unless they are (and will remain) completely independent from one another.

Satisfy a developer's urge to start new applications with a 'blank page'. The downstream effect of satisfying such an urge may be poor reuse of existing objects and unnecessary and avoidable maintenance and deployment issues.
