Adaptive Server versions 15.7 ESD #2 and later store information about database devices in the dump header. This information, along with segment maps, are used to generate a sequence of disk init, sp_cacheconfig and disk init, create database, and alter database commands for the target database during dump image creation.
Information for each database device in the dump header block includes:
Device number
Logical name
Actual device size
Physical path
Device type
Database device size
Device options
In-memory database devices are configured using caches, and information about these caches is necessary to generate disk init and sp_cacheconfig commands to create the images. Cache-specific information is therefore stored in the dump header and includes:
Cache ID
Cache name
Database cache size
Actual cache size
Device type
Cache options
