Access to storage spaces
The database server allows a user to define a method for accessing
either of the following types of storage spaces:
- A smart large object, which is in an sbspace
The database server can log, back up, and recover smart large objects.
- An external table, which is in an extspace
An extspace refers to a storage location that the HCL Informix® database server does not manage. For example, an extspace might call a path and file name that the operating system manages or another database that a different database manager controls.
The database server does not provide transaction, backup, or recovery services for data that is in an extspace.
