sybsystemdb device and database

For new installations the master device also contains the sybsystemdb database. The sybsystemdb device stores the sybsystemdb database, which stores information about transactions in progress, and which is also used during recovery.

The sybsystemdb database is required to support distributed transaction management (DTM) features. Before installation, make sure you have enough space available on the default segment to support sybsystemdb.

See Chapter 8, “Upgrading Sybase Servers” for instructions on how to create the sybsystemdb device and sybsystemdb database.

NoteFor recovery purposes, Sybase recommends that you do not create other system or user databases or user objects on the master device.
